                                        PART 2

                            SHARES AND SHARE CERTIFICATES

2.1.     Every member is entitled, without charge, to one certificate
representing the share or shares of each class held by him; provided that, in
respect of a share or shares held jointly by several persons, the Company shall
not be bound to issue more than one certificate, and delivery of a certificate
for a share to one of several joint registered holders or to his duly authorized
agent shall be sufficient delivery to all; and provided further that the Company

shares are to be redeemed within one month of the date on which they were
allotted. Any share certificate may be sent through the mail by registered
prepaid mail to the member entitled thereto at his address as recorded in the
register of members, and neither the Company nor any transfer agent shall be
liable for any loss occasioned to the member owing to any such share certificate
so sent being lost in the mail or stolen.

2.2.     If a share certificate

                   if any, as the Directors deem adequate being given, a new
                   share certificate in lieu thereof shall be issued to the
                   person entitled to such lost, stolen or destroyed
                   certificate; or

         (c)       represents more than one share and the registered owner
                   thereof surrenders it to the Company with a written request
                   that the Company issue in his name two or more certificates
                   each representing a specified number of shares and in the
                   aggregate representing the same number of shares as the
                   certificate so surrendered, the Company shall cancel the
                   Certificate so surrendered and issue in lieu thereof
                   certificates in accordance with such request.

Such sum as the Directors may from time to time fix, but not greater than the
amount prescribed under the Company Act from time to time, shall be paid to the
Company for each certificate to be issued under this Article.

2.3.     Every share certificate shall be signed manually by at least one
officer or Director of the Company, or by or on behalf of a registrar, branch
registrar, transfer agent or branch transfer agent of the Company and any
additional signatures may be printed or otherwise mechanically reproduced and,
in such event, a certificate so signed is as valid as if signed manually,
notwithstanding that any person whose signature is so printed or mechanically
reproduced shall have ceased to hold the office that he is stated on such
certificate to hold at the date of the issue of a share certificate.

2.4.     Except as required by law, statute or these Articles, no person shall
be recognized by the Company as holding any share upon any trust, and the
Company shall not be bound by or compelled in any way to recognize (even when
having notice thereof) any equitable, contingent, future or partial interest in
any share or in any fractional part of a share or (except only as by law,
statute or these Articles provided or as ordered by a court of competent
jurisdiction) any other rights in respect of any share except an absolute right
to the entirety thereof in its registered holder.

                                   ISSUE OF SHARES

3.1.     Subject to these Articles and the Memorandum and to any direction to
the contrary contained in a resolution passed at a general meeting authorizing
any increase or alteration of capital, the shares shall be under the control of
the Directors who may, subject to the rights of the holders of the shares of the
Company for the time being issued, issue, allot, sell or otherwise dispose of,
and/or grant options on or otherwise deal in, shares authorized but not
outstanding or which, having been previously issued, have been purchased or
redeemed by the Company and are available to be sold or reissued at such times,
to such persons (including Directors), in such manner, upon such terms and
conditions, and at such price or for such consideration, as they, in their
absolute discretion, may determine.

3.2.     If the Company is, or becomes, a company which is not a reporting
company and the Directors are required by the Company Act before allotting any
shares to offer them pro rata to the members, the Directors shall, before
allotting any shares, comply with the applicable provisions of the Company Act.

3.3.     Subject to the provisions of the Company Act, the Company, or the
Directors on behalf of the Company, may pay a commission or allow a discount to
any person in consideration of his subscribing or agreeing to subscribe, whether
absolutely or conditionally, for any shares in the Company, or procuring or
agreeing to procure subscriptions, whether absolutely or conditionally, for any
such shares, provided that, if the Company is not a specially limited company,
the rate of the commission and discount shall not in the aggregate exceed 25 per
centum of the amount of the subscription price of such shares.

3.4.     No share may be issued until it is fully paid and the Company shall
have received the full consideration therefor in cash, property or past services
actually performed for the Company. The value of property or services for the
purpose of this

circumstances of the transaction, no greater than fair market value.


                                        PART 4

                                   SHARE REGISTERS


4.1.     The Company shall keep or cause to be kept a register of members, a
register of transfers and a register of allotments within British Columbia, all
as required by the Company Act, and may combine one or more of such registers.
If the Company's capital shall consist of more than one class or series of
shares, a separate register of members, register of transfers and register of
allotments may be kept in respect of each class or series of shares. The
Directors on behalf of the Company may appoint a trust company registered under
the Trust Company Act to keep the register of members, register of transfers and
register of allotments or, if there is more than one class or series of shares,
the Directors may appoint a trust company, which need not be the same trust
company, to keep the register of members, the register of transfers and the
register of allotments for each class or series of share. The Directors on
behalf of the Company may also appoint one or more trust companies, including
the trust company which keeps the said registers of its shares or of a class or
series thereof, as transfer agent for its shares or such class or series
thereof, as the case may be, and the same or another trust company or companies
as registrar for its shares or such class thereof, as the case may be. The
Directors may terminate the appointment of any such trust company at any time
and may appoint another trust company in its place.

4.2.     Subject to the Company Act, the Company may keep or cause to be kept
one or more branch registers of members at such place or places, whether within
or outside the Province of British Columbia, as the Directors may from time to
time determine.

                         TRANSFER AND TRANSMISSION OF SHARES

5.1.     Subject to the provisions of the Memorandum and of these Articles that
may be applicable, any member may transfer any of his shares by instrument in
writing executed by or on behalf of such member. The instrument of transfer of
any share of the Company shall be in the form, if any, on the back of the
Company's share certificates or in such other form as the Directors may from
time to time approve. Except to the extent that the Company Act may otherwise
provide, the transferor shall be deemed to remain the holder of shares until the
name of the transferee is entered in the register of members or branch 
register of members in respect thereof.

5.2.     The signature of the registered owner of any shares, or of his duly
authorized attorney, upon an authorized instrument of transfer shall constitute
a complete and

<PAGE>


                                         -5-

sufficient authority to the Company, its directors, officers and agents to
register, in the name of the transferee as named in the instrument of transfer,
the number of shares specified therein or, if no number is specified, all the
shares of the registered owner represented by share certificates deposited with
the instrument of transfer. If no transferee is named in the instrument of
transfer, the instrument of transfer shall constitute a complete and sufficient
authority to the Company, its directors, officers and agents to register, in the
name of the person in whose behalf any certificate for the shares to be
transferred is deposited with the Company for the purpose of having the transfer
registered, the number of shares specified in the instrument of transfer or, if
no number is specified, all the shares represented by all share certificates
deposited with the instrument of transfer.

5.3.     Neither the Company nor any Director, officer or agent thereof shall 
be bound to inquire into the title of the person named in the form of 
transfer as transferee, or, if no person is named therein as transferee, of 
the person on whose behalf the certificate is deposited with the Company for 
the purpose of having the transfer registered or be liable to any claim by 
such registered owner or by any intermediate owner or holder of the 
certificate or of any of the shares represented thereby or any interest 
therein for registering the transfer, and the transfer, when registered, 
shall confer upon the person in whose name the shares have been registered a 
valid title to such shares.

5.4.      Every instrument of transfer shall be executed by the transferor and
left at the registered office of the company or at the office of its transfer
agent or branch transfer agent or registrar for registration together with the
share certificate for the shares to be transferred and such other evidence if
any, as the Directors or the transfer agent or branch transfer agent or
registrar or branch registrar may require to prove the title of the transferor
or his right to transfer the shares and the right of the transferee to have the
transfer registered. All instruments of transfer where the transfer is
registered shall be retained by the Company or its transfer agent or branch
transfer agent of registrar or branch/registrar and any instrument of transfer,
where the transfer is not registered, shall be returned to the person depositing
the same together with the share certificate which accompanied the same when
tendered for registration.

5.5.     There shall be paid to the Company in respect of the registration of
any transfer such sum, if any, as the Directors may from time to time determine.

5.6.     In the case of the death of a member, the survivor or survivors 
where the deceased was a joint registered holder, and the legal personal 
representative of the deceased where he was the sole holder, shall be the 
only persons recognized by the Company as having any title to his interest in 
the shares. Before recognizing any legal personal representative the 
Directors may require him to deliver to the Company the documents required by 
the Company Act to be produced by a person applying to effect transmission of 
shares and such other evidence as the Directors may require of the personal 
representative's appointment, and of the payment or satisfaction of all 
taxes, duties, fees and other similar assessments payable to any governmental 
authority in any applicable jurisdiction with respect to the shares arising 
out of the member's death.

5.7.     A guardian, committee, trustee, curator, tutor, personal
representative or trustee in bankruptcy of a member, although not a member
himself, shall have the same rights, privileges and obligations that attach to
the shares held by the member if the

documents required by the Company Act to be produced by a person applying to
effect transmission of shares shall have been deposited with the Company
together with such other evidence as the Directors may require of the person's
appointment. This Article does not apply on the death of a member with respect
to a share registered in his name and the name of another person in joint
tenancy.

                   applicable provision of its Memorandum or these Articles, to
                   vary or abrogate any special rights and restrictions
                   attached to any shares

and in each case by filing a certified copy of such resolution with the
Registrar but no right or special right attached to any issued shares shall be
prejudiced or interfered with unless all members holding shares of each class or
series whose right or special right is so prejudiced or interfered with consent
thereto in writing, or unless a resolution consenting thereto is passed at a
separate class or series meeting of the holders of the shares of each such class
or series by a majority of three-fourths of the votes cast, or such greater
majority as may be specified by the special rights attached to the class of
shares.

6.4.     If the Company is or becomes a reporting company, no resolution to
create, vary or abrogate any special right of conversion or exchange attaching
to any class or

required by the Company Act, the Superintendent of Brokers appointed pursuant to
the Securities Act of British Columbia shall have consented to the resolution.

6.5.     Subject to the Company Act and unless these Articles or the Memorandum
otherwise provide, the provisions of these Articles relating to general meetings
shall apply, with the necessary changes and so far as they are applicable, to a
class or series meeting of members holding a particular class or series of
shares but the quorum at a class or series meeting shall be one person holding
or representing by proxy one-third of the shares affected.

                                        PART 7

                          PURCHASE AND REDEMPTION OF SHARES

shares in accordance with the special rights and restrictions attaching thereto.
Unless the shares are to be purchased through a stock exchange or the Company is
purchasing the shares from dissenting members pursuant to the requirements of
the Company Act or from an employee or former employee of the Company or of an
affiliate of the Company or from his personal representatives, the Company shall
make its offer to purchase pro rata to every member who holds shares of the
class or series, as the case may be, to be purchased.

7.2.     If the Company proposes at its option to redeem some but not all of

         (a)       borrow money in such manner and amount, on such security,
                   from such sources and upon such terms, and conditions as

         (b)       issue bonds, debentures, and other debt obligations either
                   outright or as security for any liability or obligation of
                   the Company or any other person, and

                   whole or any part of the property and assets, of the Company
                   (both present and future).

8.2.     Any bonds, debentures or other debt obligations of the Company may be
issued at a discount, premium or otherwise, and with any special privileges as
to redemption, surrender, drawing, allotment of or conversion into or exchange
for shares or other securities, attending and voting at general meetings of the
Company, appointment or election of Directors or otherwise and may by their
terms be assignable free from any equities between the Company and the person to

subject to the provisions of the Company Act, may keep or cause to be kept one
or more branch registers of its debentureholders at such place or places as the
Directors may from time to time determine and the Directors may by resolution,
regulation or otherwise make such provisions as they think fit respecting the
keeping of such branch registers, provided that any such branch register kept
within British Columbia shall be kept by a Trust Company.

8.4.     Every bond, debenture or other debt obligation of the Company shall 
be signed manually by at least one Director or officer of the Company or by 
or on behalf of a trustee, registrar, branch registrar, transfer agent or 
branch transfer agents for the bond, debenture or other debt obligation

9.1.     Subject to any extensions of time permitted pursuant to the Company
Act, the first annual general meeting of the Company shall be held within
fifteen months from the date of incorporation, the date of amalgamation or the
effective date of a certificate of continuation, and thereafter an annual
general meeting shall be held once in every calendar year at such time (not
being more than thirteen months after the date that the last annual general
meeting was held or deemed to have been held) and place as may be determined by
the Directors.

9.2.     If the Company is, or becomes, a company which is not a reporting
company and all the members entitled to attend and vote at an annual general

9.3.      All general meetings other than annual general meetings are herein
referred to as and may be called extraordinary general meetings.

9.4.     The Directors may, whenever they think fit, convene an extraordinary
general meeting. An extraordinary general meeting, if requisitioned in
accordance with the Company Act, shall be convened by the Directors or, if not
convened by the Directors, may be convened by the requisitionists as provided in
the Company Act.

9.5.     If the Company is or becomes a reporting company, advance notice of
any general meeting at which any Director is to be elected shall be published in
the manner required by the Company Act.

9.6.     A notice convening a general meeting specifying the place, the date,

nature of that business, shall be given as provided in the Company Act and in
the manner hereinafter in these Articles mentioned, or in such other manner (if
any) as may be prescribed by ordinary resolution, whether previous notice
thereof has been given or not, to such persons as are entitled by law or under
these Articles to receive such notice from the Company. Accidental omission to
give notice of a meeting to, or the non-receipt of notice of a meeting, by any

9.7.     All the members of the Company entitled to attend and vote at a
general meeting may, by unanimous consent in writing given before, during or
after the meeting, waive or reduce the period of notice of such meeting and an

9.8.     Except as otherwise provided by the Company Act, where any special
business at a general meeting includes considering, approving, ratifying,
adopting or authorizing any document or the execution thereof or the giving of
effect thereto, the notice convening the meeting shall, with respect to such

                           PROCEEDINGS AT GENERAL MEETINGS

10.1.    All business shall be deemed special business which is transacted at

         (a)       an extraordinary general meeting other than the conduct of
                   and voting at, such meeting; and

         (b)       an annual general meeting, with the exception of the conduct
                   of, and voting at, such meeting, the consideration of the

                   Directors and Auditor, fixing or changing the number of
                   directors, the election of Directors, the appointment of the
                   Auditor, the fixing of the remuneration of the Auditor and
                   of the Directors and such other business as by these
                   Articles or the Company Act may be transacted at a general
                   meeting without prior notice thereof being given to the
                   members or any business which is brought under consideration
                   by the report of the Directors.

10.2.    No business, other than election of the chairman or the adjournment of
the meeting, shall be transacted at any general meeting unless a quorum of
members, entitled to attend and vote, is present at the commencement of the
meeting, but the quorum need not be present throughout the meeting.

10.3.    Save as herein otherwise provided, a quorum for the transaction of
business at a general meeting shall be two persons present and being, or
representing by proxy, members holding not less than one-twentieth of the issued
shares entitled to be voted at the meeting. If there is only one member the
quorum is one person present and being, or representing by proxy, such member.
The Directors, the Secretary or, in his absence, an Assistant Secretary, and the
solicitor of the Company shall be entitled to attend at any general meeting but
no such person shall be counted in the quorum or be entitled to vote at any
general meeting unless he shall be a member or proxyholder entitled to vote
thereat.

10.4.    If within half an hour from the time appointed for a general meeting,
a quorum is not present, the meeting, if convened by requisition of the members,
shall be dissolved; but otherwise it shall stand adjourned to a place on a date
and at a time, to be fixed by the chairman of the meeting before the
adjournment, which shall be not more than two weeks following the date for which
the meeting was called, or failing such designation then to the same day in the
second week following the meeting at the same time and place, in either case
without giving further notice. If at such adjourned meeting, a quorum is not
present within half an hour from the time appointed, the person or persons
present and being, or representing by proxy, a member or members entitled to
attend and vote at the meeting, shall be a quorum.

10.5.    The Chairman of the Board, if any, or in his absence the President of
the Company or in his absence a Vice-President of the Company, if any, shall be
entitled to preside as chairman at every general meeting of the Company.

10.6.    If at any general meeting neither the Chairman of the Board nor
President nor a Vice-President is present within fifteen minutes after the time
appointed for holding the meeting or is willing to act as chairman, the
Directors present shall choose some one of their number to be chairman or if all
the Directors present decline to take the chair or shall fail to so choose or if
no Director be present, the members present shall choose one of their number to
be chairman.

10.7.    The chairman may and shall, if so directed by the meeting, adjourn the
meeting from time to time and from place to place, but no business shall be
transacted at any adjourned meeting other than the business left unfinished at
the meeting from which the adjournment took place. When a meeting is adjourned
for thirty days or more, notice, but not "advance notice", of the adjourned
meeting shall be given as in the case of an original meeting or if so determined
by the Directors, by an advertisement published at least once in a daily
newspaper in Vancouver, British Columbia, or in the city where the meeting
commenced. Save as aforesaid, it shall not be necessary to give any notice of an
adjourned meeting or of the business to be transacted at an adjourned meeting.

10.8.    The chairman may propose or second a motion.

10.9.    Subject to the provisions of the Company Act, at any meeting a
resolution put to the vote of the meeting shall be decided on a show of hands,
unless (before or on the declaration of the result of the show of hands) a poll
is directed by the chairman or demanded by at least one member entitled to vote
who is present in person or by proxy. The chairman shall declare to the meeting
the decision on every question in accordance with the result of the show of
hands or the poll, and such decision shall be entered in the book of proceedings
of the Company. A declaration by the chairman that a resolution has been
carried, or carried unanimously, or by a particular majority, or lost or not
carried by a particular majority and an entry to that effect in the book of the
proceedings of the Company shall be conclusive evidence of the fact, without
proof of the number or proportion of the votes recorded in favour of, or
against, that resolution.

10.10.   In the case of an equality of votes, whether on a show of hands or on
a poll, the chairman of the meeting at which the show of hands takes place or at
which the poll is demanded shall not be entitled to a second or casting vote.

10.11.   No poll may be demanded on the election of a chairman. A poll demanded
on a question of adjournment shall be taken forthwith. A poll demanded on any
other question shall be taken as soon as, in the opinion of the chairman, is
reasonably convenient, but in no event later than seven days after the meeting
and at such time and place and in such manner as the chairman of the meeting
directs. The result of the poll shall be deemed to be the resolution of and
passed at the meeting at which the poll was demanded. Any business other than
that upon which the poll has been demanded may be proceeded with pending the
taking of the poll. A demand for a poll may be withdrawn. In any dispute as to
the admission or rejection of a vote the decision of the chairman made in good
faith shall be final and conclusive.

10.12.   Every ballot cast upon a poll and every proxy appointing a proxyholder
who casts a ballot upon a poll shall be retained by the Secretary for such
period and be subject to such inspection as the Company Act may provide.

10.13.   On a poll a person entitled to cast more than one vote need not, if he
votes, use all his votes or cast all the votes he uses in the same way.

10.14.   Unless the Company Act, the Memorandum or these Articles otherwise
provide, any action to be taken by a resolution of the members may be taken by
an ordinary resolution.

                                   VOTES OF MEMBERS

11.1.    Subject to any special voting rights or restrictions attached to any
class or series of shares and the restrictions on joint registered holders of
shares, on a show of hands every member who is present in person and entitled to
vote thereat shall have one vote and on a poll every member shall have one vote
for each share of which he is the registered holder and may exercise such vote
either in person or by proxyholder.

11.2.    Any person who is not registered as a member but is entitled to vote
at any general meeting in respect of a share, may vote the share in the same
manner as if he were a member; but, unless the Directors have previously
admitted his right to vote at that meeting in respect of the share, he shall
satisfy the directors of his right to vote the share before the time for holding
the meeting, or adjourned meeting, as the case may be, at which he proposes to
vote.

11.3.    Any corporation not being a subsidiary which is a member of the
Company may by resolution of its directors or other governing body authorize
such person as it thinks fit to act as its representative at any general meeting
or class meeting. The person so authorized shall be entitled to exercise in
respect of and at such meeting the same powers on behalf of the corporation
which he represents as that corporation could exercise if it were an individual
member of the Company personally present, including, without limitation, the
right, unless restricted by such resolution, to appoint a proxyholder to
represent such corporation, and shall, if present at the meeting, be counted for
the purpose of forming a quorum and be deemed to be a member present at the
meeting. Evidence of the appointment of any such representative may be sent to
the Company by written instrument, telegram, telex or any method of transmitting
legibly recorded messages. Notwithstanding the foregoing, a corporation being a
member may appoint a proxyholder.

11.4.    If a share is registered in the name of two or more persons, the vote
of the senior who exercises a vote, whether in person or by proxyholder, shall
be accepted to the exclusion of the votes of the other joint registered holders;
and for this purpose seniority shall be determined by the order in which the
names stand in the register of members.

Several legal personal representatives of a deceased member whose shares are
registered in his sole name shall for the purpose of this Article be deemed to
be two or more persons, as the case may be.

11.5.    A member of unsound mind entitled to attend and vote, in respect of
whom an order has been made by any court having jurisdiction, may vote, whether
on a show of hands or on a poll, by his committee, curator bonus, or other
person in the nature of a committee or curator bonus appointed by that court,
and any such committee, curator bonus, or other person may appoint a
proxyholder.

11.6.    Every member, including a member that is a corporation, entitled to
vote at a general meeting or a class meeting of the Company may, by proxy,
appoint a proxyholder as his nominee to attend and act at the meeting in the
manner, to the extent and with the power conferred by the proxy. A member may
also appoint one or more alternate proxyholders to act in the place and stead of
an absent proxyholder.

11.7.    A form of proxy shall be in writing under the hand of the appointor or
of his attorney duly authorized in writing, or, if the appointor is a
corporation either under the seal of the corporation or under the hand of a duly
authorized officer or attorney. A proxyholder need not be a member of the
Company if

         (a)       the Company is at the time a reporting company, or

         (b)       the member appointing the proxyholder is a corporation, or

         (c)       the Company shall have at the time only one member, or

         (d)       the persons present in person or by proxy and entitled to
                   vote at the meeting by resolution permit the proxyholder to
                   attend and vote; for the purpose of such resolution the
                   proxyholder shall be counted in the quorum but shall not be
                   entitled to vote 

and in all other cases a proxyholder must be a member.

11.8.    Unless otherwise ordered by the Directors, a form of proxy and the
         power of attorney or other authority, if any, under which it is
         signed, or a notarially certified copy thereof, shall be deposited at
         the registered office of the Company, or at such other place as is
         specified for that purpose in the notice convening the meeting or in
         the information circular relating thereto, not less than 48 hours
         (excluding Saturdays, Sundays and holidays) before the time for
         holding the meeting in respect of which the person named in the
         instrument is appointed. In addition to any other method of depositing
         proxies provided for in these Articles, the Directors may from time to
         time by resolution make regulations relating to the depositing of
         proxies at any place or places and fixing the time or times for
         depositing the proxies not exceeding 48 hours (excluding Saturdays,
         Sundays and holidays) preceding the meeting or adjourned meeting
         specified in the notice calling a meeting of members or in the
         information circular relating thereto and providing for particulars of
         such proxies to be sent to the Company or any agent of the Company in
         writing or by letter, telegram, telex or any method of transmitting
         legibly recorded messages so as to arrive before the commencement of
         the meeting or adjourned meeting at the office of the Company or of
         any agent of the Company appointed for the purpose of

receiving such particulars and providing that proxies so deposited may be acted
upon as though the proxies themselves were deposited as required by this Part
and votes given in accordance with such regulations shall be valid and shall be
counted.

11.9.    Unless the Company Act or any other statute or law which is applicable
to the Company or to any class or series of its shares requires any other form
of proxy, a proxy, whether for a specified meeting or otherwise shall be in the
form following, but may also be in any other form that the Directors or the
chairman of the meeting shall approve:

                                  (Name of Company)

         The undersigned, being a member of the above named Company, hereby
         appoints _________________ or failing him ____________________ as
         proxyholder for the undersigned to attend, speak and vote for and on
         behalf of the undersigned in respect of all (or ___________) shares

         the Company to be held on the day of _____________, 19__, and at any

         Signed this ___ day of _______________ 19__.

                                ______________________________
                                (Signature of Member)

11.10.   A vote given in accordance with the terms of a proxy is valid 
notwithstanding the previous death or incapacity of the member giving the 
proxy or the revocation of the proxy or of the authority under which the form 
of proxy was executed or the transfer of the share in respect of which the 
proxy is given, provided that no notification in writing of such death, 
incapacity, revocation or transfer shall have been received at the registered 
office of the Company or by the chairman of the meeting or adjourned meeting 
for which the proxy was given before the vote is taken.

11.11.   Every proxy may be revoked by an instrument in writing

         (a)       executed by the member giving the same or by his attorney
                   authorized in writing or, where the member is a corporation,
                   by a duly authorized officer or attorney of the corporation;
                   and

         (b)       delivered either at the registered office of the Company at
                   any time up to and including the last business day preceding
                   the day of the meeting, or any adjournment thereof at which
                   the proxy is to be used, or to the chairman of the meeting
                   on the day of the meeting or any adjournment thereof before
                   any vote in respect of which the proxy is to be used shall
                   have been taken

or in any other manner provided by law. A proxy shall cease to be valid one year
from its date.

                                      DIRECTORS



12.1.    The subscribers to the Memorandum of the Company are the first
Directors. The Directors to succeed the first Directors may be appointed in
writing by a majority of the subscribers to the Memorandum or at a meeting of
the subscribers, or if not so appointed, they shall be elected by the members
entitled to vote on the election of Directors and the number of Directors shall
be the same as the number of Directors so appointed or elected. The number of
Directors, excluding additional Directors, may be fixed or changed from time to
time by ordinary resolution, whether previous notice thereof has been given or
not, but notwithstanding anything contained in these Articles the number of
Directors shall never be less than one or, if the Company is or becomes a
reporting company, less than three.

12.2.    The remuneration of the Directors as such may from time to time be
determined by the Directors or, if the Directors shall so decide, by the
members. Such remuneration may be in addition to any salary or other
remuneration paid to any officer or employee of the Company as such who is also
a Director. The Directors shall be repaid such reasonable travelling, hotel and
other expenses as they incur in and about the business of the Company and if any
Director shall perform any professional or other services for the Company that
in the opinion of the Directors are outside the ordinary duties of a Director or
shall otherwise be specially occupied in or about the Company's business, he may
be paid a remuneration to be fixed by the Board, or, at the option of such
Director, by the Company in general meeting, and such remuneration may be either
in addition to, or in substitution for any other remuneration that he may be
entitled to receive. The Directors on behalf of the Company, unless otherwise
determined by ordinary resolution, may pay a gratuity or pension or allowance on
retirement to any Director who has held any salaried office or place of profit
with the Company or to his spouse or dependants and may make contributions to
any fund and pay premiums for the purchase or provision of any such gratuity,
pension or allowance.

12.3.    A Director shall not be required to hold a share in the capital of the
Company as qualification for his office but shall be qualified as required by
the Company Act, to become or act as a Director.



                                       PART 13

                          ELECTION AND REMOVAL OF DIRECTORS

13.1.    At each annual general meeting of the Company all the Directors shall
retire and the members entitled to vote thereat shall elect a Board of Directors
consisting of the number of Directors for the time being fixed pursuant to these
Articles. If the Company is, or becomes, a company that is not a reporting
company and the business to be transacted at any annual general meeting is
consented to in writing by all the members who are entitled to attend and vote
thereat such annual general meeting shall be deemed for the purpose of this Part
to have been held on such written consent becoming effective.

                                         -16-

13.2.    A retiring Director shall be eligible for re-election.

13.3.    Where the Company fails to hold an annual general meeting in
accordance with the Company Act, the Directors then in office shall be deemed to
have been elected or appointed as Directors on the last day on which the annual
general meeting could have been held pursuant to these Articles and they may
hold office until other Directors are appointed or elected or until the day on
which the next annual general meeting is held.

13.4.    If at any general meeting at which there should be an election of
Directors, the places of any of the retiring Directors are not filled by such
election, such of the retiring Directors who are not re-elected as may be
requested by the newly-elected Directors shall, if willing to do so, continue in
office to complete the number of Directors for the time being fixed pursuant to
these Articles until further new Directors are elected at a general meeting
convened for the purpose. If any such election or continuance of Directors does
not result in the election or continuance of the number of Directors for the
time being fixed pursuant to these Articles such number shall be fixed at the
number of Directors actually elected or continued in office.

13.5.    Any casual vacancy occurring in the Board of Directors may be filled
by the remaining Directors or Director. A vacancy resulting from an increase by
the members in the number of Directors may be filled by the members by ordinary
resolution or by the Directors.

13.6.    Between successive annual general meetings the Directors shall have 
power to appoint one or more additional Directors but not more than one-third 
of the number of Directors fixed pursuant to these Articles and in effect at 
the last general meeting at which Directors were elected, and the number of 
Directors shall be increased accordingly. Any Director so appointed shall 
hold office only until the next following annual general meeting of the 
Company, but shall be eligible for election at such meeting and so long as he 
is an additional Director the number of Directors shall be increased 
accordingly.

13.7.    Any Director may by instrument in writing delivered to the Company
appoint any person to be his alternate to act in his place at meetings of the
Directors at which he is not present unless the Directors shall have reasonably
disapproved the appointment of such person as an alternate Director and shall
have given notice to that effect to the Director appointing the alternate
Director within a reasonable time after delivery of such instrument to the
Company. Every such alternate shall be entitled to notice of meetings of the
Directors and to attend and vote as a Director at a meeting at which the person
appointing him is not personally present. A person may be appointed as an
alternate Director by more than one Director, and an alternate Director shall be
counted separately in determining the quorum for, and having a separate vote on
behalf of, each Director he is representing, in addition to being so counted
and voting where he is himself a Director. Every alternate Director, if
authorized by the instrument appointing them, may sign in place of the Director
who appointed him resolutions submitted to the Directors to be consented to in
writing as referred to in Article 16.9. Every alternate Director shall be deemed
not to be the agent of a Director appointing him. An alternate Director shall be
deemed to be a Director for all purposes of these Articles in the performance of
any function authorized under this Article 13.7, but shall not otherwise be
deemed to be a

Director or to have power to act as a Director. A Director may at any time by
instrument telegram, telex or any method of transmitting legibly recorded
messages delivered to the Company revoke the appointment of an alternate
appointed by him. An alternate Director may be repaid by the Company such
expenses as might properly be repaid to him if he were a Director and he shall
be entitled to receive from the Company such proportion, if any, of the
remuneration otherwise payable to the Director appointing him as such Director
may from time to time direct.

13.8.    The office of Director shall be vacated if the Director:

         (a)       resigns his office by notice in writing delivered to the
                   registered office of the Company; or

         (b)       is convicted of an indictable offence and the other
                   Directors shall have resolved to remove him; or

         (c)       ceases to be qualified to act as a Director pursuant to the
                   Company Act.

13.9.    The Company may by special resolution remove any Director before the
expiration of his period of office, and may by an ordinary resolution appoint
another person in his stead.

                            POWERS AND DUTIES OF DIRECTORS


14.1.    The Directors shall manage, or supervise the management of, the
affairs and business of the Company and shall have the authority to exercise all
such powers of the Company as are not, by the Company Act or by the Memorandum
or these Articles, required to be exercised by the company in general meeting.

14.2.     The Directors may from time to time by power of attorney or other
instrument under the seal, appoint any person to be the attorney of the Company
for such purposes, and with such powers, authorities and discretions (not
exceeding those vested in or exercisable by the Directors under these Articles
and excepting the powers of the Directors relating to the constitution of the
Board and of any of its committees and the appointment or removal of officers
and the power to declare dividends) and for such period, with such remuneration
and subject to such conditions as the Directors may think fit, and any such
appointment may be made in favour of any of the Directors or any of the members
of the Company or in favour of any corporation, or of any of the members,
directors, nominees or managers of any corporation, firm or joint venture and
any such power of attorney may contain such provisions for the protection or
convenience of persons dealing with such attorney as the Directors think fit.
Any such attorney may be authorized by the Directors to sub-delegate all or any
of the powers, authorities and discretions for the time being vested in him.

15.1.    A Director who is, in any way, directly or indirectly interested in a
proposed contract or transaction with the Company or who holds any office or
possesses any property whereby, directly or indirectly, a duty or interest might

case may be, in accordance with the provisions of the Company Act.

15.2.    A Director shall not vote in respect of any such contract or
transaction with the Company in which he is interested and if he shall do so his
vote shall not be counted, but he shall be counted in the quorum present at the
meeting at which such vote is taken. Subject to the provisions of the Company
Act, the foregoing prohibitions shall not apply to

         (a)       any such contract or transaction relating to a loan to the
                   Company, which a Director or a specified corporation or a
                   specified firm in which he has an interest has guaranteed or
                   joined in guaranteeing the

         (b)       any contract or transaction made or to be made with, or for

         (e)       the indemnification of any Director by the Company under
                   Section 152 of the Company Act.

These exceptions may from time to time be suspended or amended to any extent
approved by the Company in general meeting and permitted by the Company Act,
either generally or in respect of any particular contract or transaction or for
any particular period.

15.3.    A Director may hold any office or place of profit with the Company
(other than the office of auditor of the Company) in conjunction with his office
of Director for such period and on such terms (as to remuneration or otherwise)
as the Directors may determine and no Director or intended Director shall be
disqualified by his office from contracting with the Company either with regard
to his tenure of any such other office or place of profit or as vendor,
purchaser or otherwise, and, subject to compliance with the provisions of the
Company Act, no contract or transaction entered into by or on behalf of the
Company in which a Director is in any way interested shall be liable to be

Company for any remuneration or other benefits received by him as director,
officer or employee of, or from his interest in, such other corporation or firm,
unless the Company in general meeting otherwise directs.

                               PROCEEDINGS OF DIRECTORS

16.1.    The Chairman of the Board, if any, or in his absence, the
Vice-Chairman or in his absence, the President shall preside as chairman at
every meeting of the Directors, or if neither the Chairman of the Board nor the
Vice-Chairman nor the President is present within fifteen minutes of the time
appointed for holding the meeting or is willing to act as chairman, or, if the
Chairman of the Board, the Vice-Chairman, and the President have advised the
secretary that they will not be present at the meeting, the Directors present
shall choose one of their number to be chairman of the meeting.

16.2.    The Directors may meet together for the dispatch of business, adjourn
and otherwise regulate their meetings, as they think fit. Questions arising at
any meeting shall be decided by a majority of votes. In case of an equality of
votes the chairman shall not have a second or casting vote. Meetings of the
Board held at regular intervals may be held at such place, at such time and upon
such notice (if any) as the Board may by resolution from time to time determine.

16.3.    A meeting of the Directors or of any committee of the Directors may
take place by means of conference telephones or other communications facilities
by which means all Directors participating in the meeting can hear each other
and provided that all such Directors agree to such meeting being held in such

shall be deemed to be present at the meeting and to have so agreed and shall be
counted in the quorum therefor and be entitled to speak and vote thereat.

16.4.    A Director may, and the Secretary or an Assistant Secretary upon
request of a Director shall, call a meeting of the Board at any time. Reasonable
notice of such meeting specifying the place, day and hour of such meeting shall

alternate Directors at his address as it appears on the books of the Company or
by leaving it at his usual business or residential address or by telephone,
telegram, telex, or any method of transmitting legibly recorded messages. It
shall not be necessary to give notice of a meeting of Directors to any Director
or alternate Directors (a) who is at the time not in the Province of British


                                       Briant, Angus, McClellan & Rubenstein

Columbia or (b) if such meeting is to be held immediately following a general
meeting at which such Director shall have been elected or is the meeting of
Directors at which such Director is appointed. Accidental omission to give
notice of a meeting to or the nonreceipt of notice of a meeting by, any Director
or alternate Director shall not invalidate the proceedings at the meeting.

16.5.    Any Director of the Company may file with the Secretary a document 
executed by him waiving notice of any past, present or future meeting or
meetings of the Directors being, or required to have been, sent to him and may

filing such waiver with respect to future meetings and until such waiver
is withdrawn no notice need be given to such Director and, unless the Director
otherwise requires in writing to the Secretary, to his alternate Director of any
meeting of Directors and all meetings of the Directors so held shall be deemed
not to be improperly called or constituted by reason of notice not having been
given to such Director or alternate Director.

Directors may be fixed by the Directors and if not so fixed shall be two
Directors or, if the number of Directors is fixed at one, shall be one Director.

16.7.    The continuing Directors may act notwithstanding any vacancy in their
body, but, if and so long as their number is reduced below the number fixed
pursuant to these Articles as the necessary quorum of Directors, the continuing
Directors may act for the purpose of increasing the number of Directors to that
number, or of summoning a general meeting of the Company, but for no other
purpose.

16.8.    Subject to the provisions of the Company Act, all acts done by any
meeting of the Directors or of a committee of Directors, or by any person acting
as a Director, shall, notwithstanding that it be afterwards discovered that
there was some defect in the qualification, election or appointment of any such
Directors or of the members of such committee or person acting as aforesaid, or
that they or any of them were disqualified, be as valid as if every such person
had been duly elected or appointed and was qualified to be a Director.

16.9.    A resolution consented to in writing, whether by document, telegram,
telex or any method of transmitting legibly recorded messages or other means, by
all of the Directors shall be as valid and effectual as if it had been passed at
a meeting of the Directors duly called and held. Such resolution may be in two
or more counterparts which together shall be deemed to constitute one resolution
in writing. Such resolution shall be filed with the minutes of the proceedings
of the Directors and shall be effective on the date stated thereon or on the
latest date stated on any counterpart.

may exercise during the intervals between the meetings of the Board, all the
powers vested in the Board except the power to fill vacancies in the Board, the
power to change the membership of, or fill vacancies in, said Committee or any
other committee of the Board and such other powers, if any, as may be specified
in the resolution. The said Committee shall keep regular minutes of its
transactions and shall cause them to be recorded in books kept for that purpose,
and shall report the same to the Board of Directors at such times as the Board
of Directors may from time to time require. The Board shall have the power at
any time to revoke or override the authority given to or acts done by the
Executive Committee except as to acts done before such revocation or overriding
and to terminate the appointment or change the membership of such Committee and
to fill vacancies in it. The Executive Committee may make rules for the conduct
of its business and may appoint such assistants as it may deem necessary. A
majority of the members of said Committee shall constitute a quorum thereof.

17.2.    The Directors may from time to time by resolution constitute, dissolve
or reconstitute standing committees and other committees consisting of such
persons as the Board may determine. Every committee constituted by the Board
shall have the powers, authorities and discretions delegated to it by the Board
(which shall not include the power to fill vacancies in the Board and the power
to change the membership of or fill vacancies in any committee constituted by
the Board or the power to appoint or remove officers appointed by the Board) and
shall conform to the regulations which may from time to time be imposed upon it
by the Board.

17.3.     The Executive Committee and any other committee may meet and adjourn
as it thinks proper. Questions arising at any meeting shall be determined by a
majority of votes of the members of the committee present, and in case of an
equality of votes the chairman shall not have a second or casting vote. A
resolution approved in writing by all the members of the Executive Committee or
any other committee shall be as valid and effective as if it had been passed at
a meeting of such Committee duly called and constituted. Such resolution may be
in two or more counterparts which together shall be deemed to constitute one
resolution in writing. Such resolution shall be filed with the minutes of the
proceedings of the committee and shall be effective on the date stated thereon
or on the latest date stated in any counterpart.

                                       OFFICERS


18.1.    The Directors shall, from time to time, appoint a President and a
Secretary and such other officers, if any as the directors shall determine and
the Directors may, at any time, terminate any such appointment. No officer shall
be appointed unless he is qualified in accordance with the provisions of the
Company Act.

18.2.    One person may hold more than one of such offices except that the
offices of President and Secretary must be held by different persons unless the

tenure of office or employment shall from time to time be determined by the
Directors; such remuneration may be by way of salary, fees, wages, commission or
participation in profits or any other means or all of these modes and an officer
may in addition to such remuneration be entitled to receive after he ceases to
hold such office or leaves the employment of the Company a pension or gratuity.
The Directors may decide what functions and duties each officer shall perform

                                       PART 19

            INDEMNITY AND PROTECTION OF DIRECTORS, OFFICERS AND EMPLOYEES

19.1.    Subject to the provisions of the Company Act, the Directors shall
cause the Company to indemnify a Director or former Director of the Company and
the Directors may cause the Company to indemnify a director or former director
of a corporation of which the Company is or was a shareholder and the heirs and
personal representatives of any such person against all costs, charges and
expenses, including an amount paid to settle an action or satisfy a judgment,
actually and reasonably incurred by him or them including an amount paid to
settle an action or satisfy a judgment in a civil, criminal or administrative
action or proceeding to which he is or they are made a party by reason of his
being or having been a Director of the Company or a director of such
corporation, including any action brought by the Company or any such
corporation. The Company shall apply to the court for all approvals of the court
which may be required to make any indemnity referred to in this Part effective
and enforceable. Each Director of the Company on being elected or appointed
shall be deemed to have contracted with the Company on the terms of the
foregoing indemnity.

19.2.    Subject to the provisions of the Company Act, the Directors may cause
the Company to indemnify any officer, employee or agent of the Company or of a
corporation of which the Company is or was a shareholder (notwithstanding that
he is also a Director) and his heirs and personal representatives against all
costs, charges and expenses whatsoever incurred by him or them and resulting
from his acting as an officer, employee or agent of the Company or such
corporation. In addition the Company shall indemnify the Secretary or an
Assistant Secretary of the Company (if he shall not be a full time employee of
the Company and notwithstanding that he is also a Director) and his respective
heirs and legal representatives against all costs, charges and expenses
whatsoever incurred by him or then; and arising out of the functions assigned to
the Secretary by the Company Act or these Articles and each such Secretary and
Assistant Secretary shall on being appointed be deemed to have contracted with
the Company on the terms of the foregoing indemnity.

                                         -23-

19.3.    The failure of a Director or officer of the Company to comply with the
provisions of the Company Act or of the Memorandum or these Articles shall not
invalidate any indemnity to which he is entitled under this Part. 

19.4.    The Directors may cause the Company to purchase and maintain insurance 
for the benefit of any person who is or was serving as a Director, officer, 
employee or agent of the Company or as a director, officer, employee or agent 
of any corporation of which the Company is or was a shareholder and his heirs 
or personal representatives against any liability incurred by him as such 
Director, director, officer, employee or agent.

                                       PART 20

                                DIVIDENDS AND RESERVE

20.1.    The Directors may from time to time declare and authorize payment of
such dividends, if any, as they may deem advisable and need not give notice of
such declaration to any member. No dividend shall be paid otherwise than out of
funds and/or assets properly available for the payment of dividends and a
declaration by the Directors as to the amount of such funds or assets available
for dividends shall be conclusive. The Company may pay any such dividend wholly
or in part by the distribution of specific assets and in particular by paid up
shares, bonds, debentures or other securities of the Company or any other
corporation or in any one or more such ways as may be authorized by the Company
or the Directors and where any difficulty arises with regard to such a
distribution the Directors may settle the same as they think expedient, and in
particular may fix the value for distribution of such specific assets or any
part thereof, and may determine that cash payments in substitution for all or
any part of the specific assets to which any members are entitled shall be made
to any members on the basis of the value so fixed in order to adjust the rights
of all parties and may vest any such specific assets in trustees for the persons
entitled to the dividend as may seem expedient to the Directors.

20.2.    Any dividend declared on shares of any class or series by the
Directors may be made payable on such date as is fixed by the Directors.

20.3.    Subject to the rights of members (if any) holding shares with special
rights as to dividends, all dividends on shares of any class or series shall be
declared and paid according to the number of such shares held.

20.4.    The Directors may, before declaring any dividend, set aside out of the
funds properly available for the payment of dividends such sums as they think
proper as a reserve or reserves, which shall, at the discretion of the
Directors, be applicable for meeting contingencies, or for equalizing dividends,
or for any other purpose to which such funds of the Company may be properly
applied, and pending such application may, at the like discretion, either be
employed in the business of the Company or be invested in such investments as
the Directors may from time to time think fit. The Directors may also, without
placing the same in reserve, carry forward such funds, which they think prudent
not to divide.

20.5.    If several persons are registered as joint holders of any share, any
one of them may given an effective receipt for any dividend, bonuses or other
moneys payable in respect of the share.

20.6.    No dividend shall bear interest against the Company. Where the
dividend to which a member is entitled includes a fraction of a cent, such
fraction shall be disregarded in making payment thereof and such payment shall
be deemed to be payment in full.

20.7.    Any dividend, bonuses or other moneys payable in cash in respect of
shares may be paid by cheque or warrant sent through the post directed to the
registered address of the holder, or in the case of joint holders, to the
registered address of that one of the joint holders who is first named on the
register, or to such person and to such address as the holder or joint holders
may direct in writing. Every such cheque or warrant shall be made payable to the
order of the person to whom it is sent. The mailing of such cheque or warrant
shall, to the extent of the sum represented thereby (plus the amount of any tax
required by law to be deducted) discharge all liability for the dividend, unless
such cheque or warrant shall not be paid on presentation or the amount of tax so
deducted shall not be paid to the appropriate taxing authority.

20.8.    Notwithstanding anything contained in these Articles the Directors may
from time to time capitalize any undistributed surplus on hand of the Company
and may from time to time issue as fully paid and non-assessable any unissued
shares, or any bonds, debentures or debt obligations of the Company as a
dividend representing such undistributed surplus on hand or any part thereof.



                                       PART 21

                            DOCUMENTS, RECORDS AND REPORTS

21.5.    Every member shall be entitled to be furnished once gratis on demand
with a copy of the latest annual financial statement of the Company and, if so
required by the Company Act, a copy of each such annual financial statement and
interim financial statement shall be mailed to each member.

                                       NOTICES


22.1.    A notice, statement or report may be given or delivered by the Company
to any member either by delivery to him personally or by sending it by mail to
him to his address as recorded in the register of members. Where a notice,
statement or report is sent by mail, service or delivery of the notice,
statement or report shall be deemed to be effected by properly addressing,
prepaying and mailing the notice, statement or report and to have been given on
the day, Saturdays, Sundays and holidays excepted, following the date of
mailing. A certificate signed by the Secretary or other officer of the Company
or of any other corporation acting in that behalf for the Company that the
letter, envelope or wrapper containing the notice, statement or report was so
addressed, prepaid and mailed shall be conclusive evidence thereof.

22.2.    A notice, statement or report may be given or delivered by the Company
to the joint holders of a share by giving the notice to the joint holder first
named in the register of members in respect of the share.

22.3.     A notice, statement or report may be given or delivered by the
Company to the persons entitled to a share in consequence of the death,
bankruptcy or incapacity of a member by sending it through the mail prepaid
addressed to them by name or by the title of representatives of the deceased or
incapacitated person or trusted of the bankrupt, or by any like description, at
the address (if any) supplied to the Company for the purpose by the persons
claiming to be so entitled, or (until such address has been so supplied) by
giving the notice in a manner in which the same might have been given if the
death, bankruptcy or incapacity had not occurred.

22.4.    Notice of every general meeting or meeting of members holding a class
or series of shares shall be given in a manner hereinbefore authorized to every
member holding at the time of the issue of the notice or the date fixed for
determining the members entitled to such notice, whichever is the earlier,
shares which confer the right to notice of and to attend and vote at any such
meeting. No other person except the auditor of the Company and the Directors of
the Company shall be entitled to receive notices of any such meeting.

                                     RECORD DATES


23.1.    The Directors may fix in advance a date, which shall not be more than
the maximum number of days permitted by the Company Act preceding the date of

adjournment thereof, or entitled to receive payment of any such dividend or for
any other proper purpose and, in such case, notwithstanding anything elsewhere

provided in the preceding Article the date on which the notice is mailed or on
which the resolution declaring the dividend is adopted, as the case may be,

terminated for failure of KELMINE to pay the monthly minimum royalty of

that the lease has terminated.

               III.A.3.  Such rights as LESSOR has in all the above described
unpatented lode mining claims are hereinafter referred to as the "MINING
CLAIMS."

               III.A.4.  Such right to water available for use in processing
copper bearing ores from the property above described as the LESSOR has is
hereinafter referred to as the "WATER RIGHT".

               III.A.5.  LESSOR has acquired the rights of KELMINE in the SX-EW
under the BILL OF SALE.

               III.A.6.  COSTANZAS hold the STATE LEASE. COSTANZAS, in the
COSTANZA-KUNKEL DEED, intended to convey to RAY and CLEMONS the right to mine
copper on the STATE LEASE to a depth of 500 feet. The State of Utah did not
accept that deed and required that COSTANZAS make a separate assignment to RAY
and CLEMONS. Such an assignment was made by COSTANZAS and approved by the State
of Utah. LESSOR believes that it can acquire the interest of RAY, CLEMONS,
BROWN, GILLES, BURTON and DEARTH in the STATE LEASE.

               III.A.7.  All of the right, title, interest and expectancy of the

                                       19

<PAGE>

                    III.B.2.b.  LESSEE diligently commencing and continuing to
work on a copper processing facility to process copper ores from the LEASED
PREMISES.

                    III.B.2.c.  LESSEE commencing production from the LEASED
PREMISES in commercial quantities within five (5) years after such approval is
secured. 

                    III.B.2.d.  LESSOR using its best efforts to acquire all the
right, title and interest of RAY, CLEMONS, BROWN, GILLES, BURTON and/or DEARTH
in the STATE LEASE, including, but not limited to, the securing of the approval

               III.B.3.  Upon the execution of this NEW MINERALS LEASE by the
LESSOR, LESSEE shall immediately pay to LESSOR the sum of $1,500.00 which shall
not be recoverable by LESSEE out of the production royalty hereinafter provided.

               III.B.4.  LESSOR and LESSEE agrees to execute such additional
documents as are reasonably necessary to insure and confirm that the OTHER
PROPERTY is covered by this NEW MINERALS LEASE. Without limiting the foregoing,

execute, acknowledge and deliver to LESSEE, in recordable form, an amendment or
amendments to this MINERALS LEASE or any other documents which better describe
the LEASED PREMISES.


                                       20

<PAGE>

               III.B.5.  The rights of LESSOR as to some of the LEASED PREMISES
are in the form of an ownership of the copper and some other minerals and in
other parts of the LEASED PREMISES the rights are in the form of leases and
subleases so that while this instrument is characterized as a "lease" it is a
lease as to some portions of the LEASED PREMISES and a sublease as to the
balance.

               III.B.6.  This NEW MINERALS LEASE shall commence on the date
first above set forth in this instrument, run thereafter for a primary term of
ten (10) years and continue thereafter as long as minerals are being produced
from the LEASED PREMISES in commercial quantities, unless sooner terminated or
surrendered as hereinafter set forth; provided, however, that in the event
production of minerals in commercial quantities occurred during the primary term
and thereafter ceases because it is no longer commercially feasible to continue
the production of minerals from the LEASED PREMISES, this NEW MINERALS LEASE
shall continue beyond the expiration of the primary term without the necessity
of production of minerals and/or metals in commercial quantities as long as it
is not commercially feasible to continue production and as long as LESSEE
performs all the covenants it is obligated to perform hereunder including, but
not limited to, the covenant to pay the monthly minimum advance royalty
hereinafter


                                       21

<PAGE>

provided.

               III.B.7.  LESSEE shall pay LESSOR a royalty equal to the
percentage (hereinafter set forth) of the NET PROCEEDS (hereinafter defined)
received for all mineral, and/or metals, mined and removed from the LEASED
PREMISES and processed and sold in any chemical, mineral or metallic form,
hereinafter referred to as the "PRODUCT." The percent of the royalty shall be
determined by the amount of NET PROCEEDS per pound of PRODUCT sold during the
calendar month. If the NET PROCEEDS per pound of PRODUCT sold during the
calendar month is less than $1.00, the royalty percentage shall be five percent
(5%). If the NET PROCEEDS per pound of PRODUCT sold during the calendar month is
from $1.00 up to and including $1.20, the royalty percentage shall be five and
one-half percent (5 1/2%). If the NET PROCEEDS per pound of PRODUCT sold during
the calendar month is more than $1.20, the royalty percentage shall be six
percent (6%). The term "NET PROCEEDS" means the gross amount received by LESSEE,
after deducting freight and handling charges from the point of final treatment
to the point of final sale, from an arms-length bona fide sale of PRODUCT to a
purchaser which has no financial interest of any kind in the LESSEE or its
operations on the LEASED PREMISES or to a purchaser in which the LESSEE has no
financial interest of any kind. If the LESSEE makes a sale which


                                       22

<PAGE>

is not arms-length and bona fide and/or to a purchaser which has a financial
interest in the LESSEE or its operations on the LEASED PREMISES Or to a
purchaser in which the LESSEE has a financial interest, the NET PROCEEDS shall
be based upon the MARKET VALUE of the contained metals and/or minerals in the
PRODUCT. The term MARKET VALUE of contained metals and/or minerals shall mean
the average of U.S. Producer or major Suppliers prices, as quoted in Metals Week
and as published in Engineering and Mining Journal (E&MJ) for the month in
which the metals and/or minerals are sold.

               III.B.8.  LESSEE shall pay all royalties previously reserved and
all royalties due and owing on the underlying leases and subleases with respect
to the LEASED PREMISES. LESSEE shall perform all other obligations which LESSOR
and RAY, BROWN, GILLES, BURTON and DEARTH, and/or any of them, are obligated to
perform in those leases and subleases. Without in any way limiting the
foregoing, LESSEE shall pay all royalty on the STOCKPILE which may be owing the
State of Utah or any other person or entity. 


               III.B.9. LESSEE shall be entitled to deduct the royalty which 
it pays under Section III.B.8 (other than the royalty which it pays on the 
STOCKPILE for which it shall not be entitled to any deduction) on a 
particular PRODUCT from the

                                       23

<PAGE>

royalty due LESSOR under Section III.B.7. on that same PRODUCT, provided that
the percentage of the royalty due LESSORS on that particular PRODUCT shall not,
in any event, be reduced to less than one and one-half percent (1 1/2%) so that
irrespective of the amount of the underlying royalty paid by LESSEE on a
particular PRODUCT, LESSOR shall always receive a royalty of at least one and
one-half percent (1 1/2%) on that PRODUCT. As an example and by way of
illustration, the percentage of the underlying royalty on the FEE LAND is six
percent (6%) and based on net smelter returns. If the NET PROCEEDS from PRODUCT
from the FEE LAND for a calendar month is such that the underlying royalty under
Section III.B.S. is more than the amount of royalty due LESSOR under Section
III.B.7., LESSEE would be obligated to pay LESSOR on that PRODUCT, in addition
to the underlying royalty to be paid to the persons or entities entitled
thereto, a royalty of one and one-half percent (1 1/2%) under Section III.B.7.

               III.B.10.  LESSEE shall prepare and maintain such records as are
reasonably necessary to calculate the royalty due LESSORS hereunder and the
royalty due on the underlying leases and subleases. LESSEE shall, on written
request of LESSORS, furnish copies of such records to LESSOR.

               III.B.11.  Commencing with the month of April, 1988, LESSEE shall
pay LESSOR a monthly minimum advance


                                       24

<PAGE>

royalty, which shall be due and payable on the first day of each month, as
follows:

     For the months commencing with the month of April, 1988, and continuing
     through the month of March, 1989, the sum of $1,250.00 per month; 
     For the months commencing with the month of April, 1989, and continuing
     through the month of March, 1990, the sum of $1,500.00 per month; 
     For the months commencing with the Month of April, 1990, and continuing
     through the month of March, 1991, the sum of $2,000.00 per month; 
     For the months commencing with the month of April, 1991, and continuing
     through the month of March 1992, the sum of $2,500.00 per month; and 
     For each and every month after March, 1992, and continuing as long as this
     NEW MINERALS LEASE remains in effect, the sum of $3,000.00 per month.

LESSEE shall be entitled to credit this monthly minimum advance royalty against
the production royalty to which the LESSOR is entitled as set forth above.
LESSEE shall not be entitled to any credit for the minimum payments made by
KELMINE under the KUNKEL-KELMINE LEASE.

               III.B.12.  The following provisions shall be applicable to "WASTE
MATERIAL" which is defined as material mined or extracted from the LEASED
PREMISES which LESSEE in its sole discretion determines not to sell because of
its mineral content, and LESSEE'S determination shall be final and conclusive:

                    III.B.12.a.  LESSOR agrees that WASTE MATERIAL may be mined
or otherwise extracted without obligation upon LESSEE to replace the same. At no
time during the term of


                                       25

<PAGE>

this NEW MINERALS LEASE or at any time thereafter shall LESSEE be required to
remove any WASTE MATERIAL deposited by LESSEE on the LEASED PREMISES, except as
otherwise provided by applicable governmental laws, rules and regulations in
full force and effect on or before the termination of this NEW MINERALS LEASE.

                    III.B.12.b.  All WASTE MATERIAL on the LEASED PREMISES prior
to surrender or termination of this MINERALS LEASE shall be the property of
LESSEE, and LESSOR shall have no right, title or interest whatsoever therein and
thereto until this NEW MINERALS LEASE is surrendered or terminated.

                    III.B.12.c.  All WASTE MATERIAL on the LEASED PREMISES after
surrender or termination of this NEW MINERALS LEASE shall be the property of
LESSOR, and LESSEE shall have no right, title or interest whatsoever therein or
thereto after this MINING LEASE is surrendered or terminated.

               III.B.13.  With respect to taxes:

                    III.B.13.a.  LESSEE agrees to pay all taxes levied and
assessed against the SX-EW, all equipment of LESSEE on the LEASED PREMISES, and
any improvements placed on the LEASED PREMISES by LESSEE.

                    III.B.13.b.  The relationship (in terms of percentage) which
the total royalty which LESSOR receives hereunder during a given taxing period
bears to the total NET


                                       26

<PAGE>

PROCEEDS for the same period shall be established by dividing the total royalty
received by LESSOR by the total NET PROCEEDS. LESSOR agrees to pay that
established percentage and LESSEE agrees to pay the balance of such taxes,
assessments, or other governmental levies which are assessed, levied or imposed:

                         III.B.13.b.(1)  Against the LEASED PREMISES solely by
reason of LESSEE's operations on the LEASED PREMISES.

                         III.B.13.b.(2)  Against the minerals in or on the
LEASED PREMISES in an unsevered state.

                         III.B.13.b.(3)  Any occupation, severance, production
or net proceeds of mines taxes, if any, imposed for, resulting from or measured
by reference to the removal of ore and or minerals by the LESSEE.

                    III.B.13.c.  LESSEE shall not be obligated to pay any taxes
levied, imposed or assessed against, or measured by reference to operations upon
the LEASED PREMISES which are not conducted by or on behalf of LESSEE under the
terms of this NEW MINERALS LEASE. In the event LESSOR fails to pay when due any
taxes, assessments or other governmental levy against the LEASED PREMISES (which
LESSOR is obligated to pay under this NEW MINERALS LEASE) LESSEE may, but shall
not be obligated to, pay such taxes, assessments or levies, together


                                       27

<PAGE>

with any penalty that may be imposed for failure to pay such when due. LESSOR
agrees to reimburse LESSEE for any payments made for LESSOR hereunder, together
with interest at the rate of 10% per annum from the date such payment is made by
LESSEE, which reimbursement shall be made within ten (10) days after LESSEE has
given written notice to LESSOR that LESSEE has paid such taxes, assessments or
levies. LESSEE shall specify the amount of such taxes, assessments or levies in
its notice to LESSOR. If such reimbursement is not made as provided herein,
LESSEE shall have the right to withhold payment of and retain as its sole
property any and all royalty (including the monthly minimum advance royalty
provided above) thereafter due and payable to LESSOR until the amount of royalty
withheld equals the reimbursement due LESSEE.

               III.B.14.  LESSOR shall have the right to claim the depletion
allowance applicable to the royalty paid LESSORS hereunder.

               III.B.15.  With respect to liens, damages, liability and
insurance:

                    III.B.15.a.  LESSEE agrees to indemnify LESSORS against, and
hold LESSOR harmless from any and all claims or liability for injury to or death
of persons or for damages to property other than the LEASED PREMISES, resulting
from LESSEE's


                                       28

<PAGE>

ations hereunder. LESSEE further agrees to indemnify LESSOR 
nst and hold LESSOR harmless from any and all claims or
ility for materials or labor resulting from LESSEE's
ations hereunder on the LEASED PREMISES. LESSEE's
gations hereunder shall not apply to any claim unless LESSOR
fy LESSEE of the existence of such claim as soon as it
mes known to LESSOR, and further notifies LESSEE of the
itution of any action, suit or legal proceeding on such claim
oon as the institution of such action, suit, or other
eedings become known to LESSOR and LESSEE is given the sole

tain workmen's compensation and tenant liability insurance
ed by a company or companies acceptable to LESSOR, covering
operations by LESSEE under this NEW MINERALS LEASE, showing
limits of the insurers liability to be not less than:

                                BODILY INJURY:  

                    Each Person                $500,000
                    Each Accident            $1,000,000
                    Property Damage            $500,000
                    Combined Limit           $1,000,000

<PAGE>

LESSEE shall deliver to LESSOR certificates of all insurance required under this
insurance clause.

                    III.B.15.c.  If LESSOR shall fail to pay any and all amounts
due hereunder, or duly to satisfy and discharge any mortgage or lien on the
LEASED PREMISES, or shall suffer or permit any lien or encumbrance to be imposed
upon the LEASED PREMISES, LESSEE may, at its own option, but shall not be
obligated to, pay any or all unpaid amounts due and payable under, or satisfy
and discharge any such mortgage, lien or encumbrance which is unpaid and payable
and LESSEE may reimburse itself for any such payment of any such amount so paid
or for payments and costs of paying, satisfying and discharging any such
mortgage, lien or encumbrance, by withholding and retaining as its sole property
from royalties (including the monthly minimum advance royalty) due and payable
hereunder the amounts paid by LESSEE. In case of payment, discharge or
satisfaction of a mortgage, lien or encumbrance LESSEE shall have all the rights
and remedies against LESSOR which the mortgagee or lienor or the holder of such
encumbrance had against the LESSOR immediately prior to the time of such
payment, satisfaction or discharge. Upon the request of LESSEE, LESSOR shall
promptly make, execute, acknowledge and deliver to LESSEE any and all
instruments which LESSEE in its sole judgment shall deem necessary or desirable
to


                                       30

<PAGE>

effectuate fully the provisions of this Section.

               III.B.16.  LESSOR, or their representative, at their sole risk
and at their sole cost and expense, and subject to such reasonable safety
regulations as may be prescribed by LESSEE, may have access to the LEASED
PREMISES during regular business hours solely for the purpose of inspection of
LESSEE's operations on the LEASED PREMISES.

               III.B.17.  LESSEE will conduct its operations on the LEASED
PREMISES in accordance with applicable governmental laws, rules and regulations.
Without in any way limiting the foregoing, LESSEE will strictly comply with all
reclamation requirements and all MSHA requirements now in effect or which may
later become applicable and particularly those relating to safety training and
record keeping. LESSEE makes no express or implied warranty, covenant or
agreement relating to the exploration, development, mining or other operation of
or upon the LEASED PREMISES or the marketing of any ore or mineral therefrom.
The conduct of any such exploration, development, mining or other operations, or
marketing, and the nature, manner or extent thereof, shall be matters to be
determined within the sole discretion of LESSEE. LESSEE shall have no
obligation, liability or responsibility whatsoever to LESSOR for damages or
injury to the LEASED PREMISES arising out of, or caused by or in any way 


                                       31

<PAGE>

connected with the operations conducted by LESSEE upon, in and through the
LEASED PREMISES.

               III.B.18.  LESSEE may, at any time and from time to time during
the term of this Lease, execute and deliver to LESSORS, in accordance with the
notice provisions hereinafter set forth, or deliver for recording to the
RECORDER'S OFFICE a quitclaim deed, quitclaiming to LESSOR or its successors in
interest all or any part of the LEASED PREMISES and immediately upon such
delivery this NEW MINERALS LEASE shall terminate with respect to such part or
all, as the case may be, of the LEASED PREMISES, and LESSEE shall be relieved of
all obligations, liability or responsibility of every character whatsoever
thereafter accruing with respect to that part of all, as the case may be, of the
LEASED PREMISES. If such delivery is to the RECORDER'S OFFICE, LESSEE shall
deliver a copy of such quitclaim deed to LESSORS.

               III.B.19.  LESSOR shall have no right to terminate this NEW
MINERALS LEASE unless LESSEE shall fail to perform according to the terms of
this NEW MINERALS LEASE and LESSOR shall give written to LESSEE specifying the
nature of the default. If LESSEE shall not correct such default within thirty
(30) days after said notice is given, this NEW MINERALS LEASE shall terminate.


                                       32

<PAGE>

               III.B.20.  Surrender or termination of this NEW MINERALS LEASE as
provided herein shall not relieve the LESSEE of its obligations hereunder which
remain unperformed at the time of the surrender or termination including, but
not limited to, the obligation to pay all accrued royalties (including the
monthly minimum advance royalty) , to pay its share of the taxes as above
provided and to perform the reclamation work as above provided.

               III.B.21.  LESSEE shall make every reasonable effort to care for
the SX-EW and particularly to protect the electrical parts. In the event LESSEE
does not use the SX-EW, or any part thereof, for the purpose for which it was
acquired, that is, to process leach solutions from the LEASED PREMISES, within
five years of the date of this NEW MINERALS LEASE, at the sole discretion of
LESSOR the unused part shall no longer be a part of the LEASED PREMISES and
LESSOR may, at its sole discretion, remove and dispose of the same upon written
notice to the LESSEE. Subject to the above, LESSEE shall have the right at any
time within sixty (60) days following the surrender or termination of this NEW
MINERALS LEASE, with respect to all or any parts of the LEASED PREMISES to
remove any and all buildings, structures, plants, shops, mills, machinery
equipment, lines and facilities. 

               III.B.22.  LESSEE will maintain the DATA and


                                       33

<PAGE>

make available for examination and copying by LESSOR, or its duly authorized
representatives, the DATA, all additional survey maps, drill hole data,
including drill hole chip boards, ore reserve calculations, mining plans,
reclamation plans and supporting data used to obtain state and/or federal
environmental and operating or mining permits, assay, metallurgical and
feasibility reports relating to the LEASED PREMISES and any maps or diagrams or
mine workings upon the LEASED PREMISES which LESSEE has in its possession
or-control.

               III.B.23.  Any notice or communication to the parties hereto, or
quitclaim deed shall be deemed to have been sufficiently given for all purposes
hereof if mailed by U. S. Registered or Certified mail, postage prepaid, return
receipt requested, addressed as follows, and the date on the U. S. Post office
receipt shall be deemed to be the date of mailing:

          To LESSOR:                         To LESSEE:

          Lisbon Copper Ltd.                 MLP Associates, Ltd.

          33 Holiday Haven                   Golden, Colorado 80401
          Moab, Utah 84532

               III.B.24.  LESSEE agrees that it will not assign, sublease or
transfer all or any of its rights under this lease without first obtaining the
written consent of LESSOR. LESSOR agrees that it will not unreasonably withhold
that

                                       34

<PAGE>

consent.

               III.B.25.  LESSEE's failure to perform or comply with a
particular provision of this NEW MINERALS LEASE shall be excused if such failure
to perform or comply with that particular provision is caused by circumstances
or conditions beyond the reasonable control of LESSEE, including but not limited
to the following: severe weather, unusual mining casualty, civil or military
orders, regulations or authority, insurrections, riots, strikes, acts of God,
war or hostilities between any nations, embargoes, governmental orders or
regulations, fire accident, explosion, flood, lockouts, differences with
workman, delays of carriers, lack of transportation facilities, commandeering or
requisitioning by the government, inability to obtain raw materials or the
insurance required hereon, curtailment of or failure in obtaining sufficient
electrical power. Circumstances or conditions which prevent the performance of a
particular provision herein shall only excuse performance of the particular
provision, the performance of which is prevented by those circumstances or
conditions, and shall not excuse the performance of any of the other provisions
of this NEW MINERALS LEASE. No circumstances or conditions shall excuse LESSEE
from its obligation to pay the monthly minimum advance royalty under Section
III.B.11.

                      ARTICLE 1. MINERALS COVERED BY THIS LEASE

    This Mineral Lease covers the following-described leased mineral
substances with the boundaries of the above-described lands, to-wit:

    METALLIFEROUS MINERALS

    "Metalliferous Minerals" are herein defined to include any ore containing
any of the following minerals:  Aluminum, Antimony, Arsenic, Beryllium,
Bismuth, Cadmium, Chromium, Cecium, Columbium, Cobalt, Copper, Flourspar,
Gallium, Gold, Germanium, Hafium, Iron, Indium, Lead, Mercury, Manganese,
Molybdenum, Nickel, Platinum, Group Metals, Radium, Selenium, Scandium, Silver,
Rare Earth Metals, Rhenium, Tantalium, Tin, Thorium, Tungsten, Thallium,
Tellurium, Vanadium, Uranium, Zinc, together with other minerals which are found
in association with said specified minerals in such a manner that they cannot be
mined separately.

    In the event Lessee, or the operator or any contractor for Lessee, shall
discover within said lands some mineral or minerals other than the mineral or
leased substances covered by this lease, Lessee shall promptly notify the Lessor
of the kind or nature of such mineral or minerals not included in this lease.

           ARTICLE II. PRIMARY TERM AND POSSIBLE EXTENSION OF TERM OF LEASE

    This lease is granted for a primary term of TEN (10) years commencing on
the first day of January next succeeding the date hereinabove first written and
as long thereafter as the leased substances shall be produced in commercial
quantities from the above-described lands, on condition that Lessee shall
perform the terms and provisions required to be performed by Lessee including
payment of rents and royalties within the times required herein; provided
however, that it is expressly agreed that at the end of each period of ten (10)
years following the effective date of this lease, the State of Utah as Lessor
shall have the right to readjust the terms and conditions of this lease as may
then be determined to be in the best interest of the State of Utah as trustee-
owner of the mineral estate. In the event of failure or refusal of the Lessee to
accept and agree to the readjustment of the terms and conditions submitted by
Lessor at the end of such ten (10)-year period, such failure or refusal to
accept such readjustment of terms, conditions, or royalty shall operate to
forfeit any right to extension of the term of this Mineral Lease and terminate
this lease except for the rights of the State of Utah to recover any royalties
then owing the State and/or any damages for which Lessee may be liable. This
lease will not be extended beyond the end of the thirtieth year-except by the
production of the leased substances in commercial quantities from the leased
lands. If Lessee ceases production of leased substances in commercial quantities
this lease will terminate one (1) year from the date of last commercial
production, unless Lessee commences commercial production at least three (3)
months prior to the end of such year and such commercial production then
continues for at least six (6) months.

                       ARTICLE IV. RIGHTS TO THE SURFACE ESTATE

    If the surface estate of all or sane portion of the hereinabove-described
lands is owned by the Lessor, Lessee shall be entitled to use reasonably and
prudently such portions of the surface estate owned by Lessor as shall be
reasonably necessary to explore and prospect for, mine, drill, remove, and
dispose of the leased mineral substances, including permission to establish and
maintain in, a safe condition on the surface estate owned by Lessor, access
roads, communication lines, tanks, pipelines, reservoirs, mills, processing
plants, reduction works, dumps, and other essential structures, facilities,
machinery, and equipment, reasonably necessary and expedient for the
economic operation of the leasehold and in furtherance of production, treatment,
and disposition of the leased substances under this lease. Such surface uses
shall be exercised subject to the rights reserved to the State of Utah as
provided in Article V hereof, and without unreasonable interference with the
rights of any prior or subsequent lessee of the State of Utah under the program
of multiple use.

    If the surface estate of any portion of the described lands is not owned by
the State of Utah, except for a reserved right of entry to the mineral estate or
mineral estates, the Lessee may exercise such right of entry to the mineral
estate covered by this lease, at the sole cost and expense of Lessee herein and
without cost to the State of Utah. If any damage is caused directly or 
indirectly to the surface estate by the Lessee or by the contractor or operator
for Lessee, Lessee shall make proper restitution and indemnify the surface
owner or owners. Lessee also shall make proper rehabilitation as required by
the Utah Mined Land Reclamation Act and as required by all lawful rules and
regulations adopted thereunder.

    Lessor will require a bond to be posted or other security given to the
State to be filed with Lessor or any other State agency or officer in a
principal amount determined by Lessor to be adequate to assure appropriate
reclamation and restitution for and damage to the surface estate.

                   ARTICLE V. EXCEPTIONS AND EXCLUSIONS FROM LEASE

    Lessor hereby excepts and reserves from the operation of this lease the
following rights and privileges:

of said lands above described, Lessor retains the right to use, lease, sell, or
otherwise dispose of the surface estate in said lands or any part thereof, under
existing State laws or laws subsequently enacted, insofar as such surface is not
essential for the Lessee herein in exploration, prospecting for, mining,
drilling, removal, or disposal of the leased substances covered by this lease,
to the extent that such use, lease, or sale of the surface estate does not
unreasonably interfere with the rights granted to the Lessee herein. Lessor
shall notify Lessee herein of any such sale, lease, use, or other disposition of
the surface estate.

                     ARTICLE VI. PAYMENT OF RENTALS AND ROYALTIES

lease. All rentals paid shall be credited against actual Production Royalties
for the lease year in which they shall accrue, but such rentals shall not be
credited against the Minimum Royalties under subparagraph "Fourth" of this
ARTICLE VI.

    SECOND: "Lessee shall pay lessor a production royalty on the basis of 8% in

date of termination, surrender or expiration of this lease or from the date 
when Lessee shall specify in writing the acquisition costs of such other 
water rights, whichever date is the later date. Unless Lessor accepts such 
written offer to convey such rights at the actual acquisition costs within 
said period of 45 days, Lessor shall be deemed to have rejected the offer.

Division of Oil, Gas, and Mining, shall be entitled to a true and correct copy
thereof, together with the proposed plans of operation.

    After Lessor receives notice of intent to commence mining operations, 
upon request of the Lessor, the Lessee shall furnish a bond with an approved 
corporate surety company authorized to transact business in the State of 
Utah, or such other security acceptable to the Lessor, in an amount to be 
determined by Lessor, after taking into account the value of the land and the 
amount of potential damage which likely will result from such proposed mining 
operations, and which bond or other security shall be conditioned upon 
payment of all rentals and royalties from the leasehold and other sums which 
may become payable to the Lessor, and to assure full compliance with the 
terms and conditions of this lease and compliance with all Rules and 
Regulations of the Board of State Lands & Forestry and all Rules and 
Regulations of any other State agency having jurisdiction over mining 
operations, and also conditioned upon payment of all damages to the surface 
and improvements thereon if this lease covers surface estate or some portion 
of the surface estate which has been sold or otherwise leased, and any damage 
caused by Lessee to any other lessee of the State of Utah with respect to 
said land. Such bond or other security furnished prior to commencement of 
development of the leasehold may be increased in such reasonable amounts as 
the Lessor may require after discovery of any of the leased substances.

    If the plan of mining development or mining operations includes
core-drilling, the plan of operations shall disclose the locations of
core-drilling operations.

       ARTICLE XIII. ALL OPERATIONS TO BE CONDUCTED IN A LAWFUL, PRUDENT MANNER

    Lessee shall conduct all operations under this lease in a lawful, prudent,
and good workmanlike manner for the effective and safe production of the mineral
substances covered by this lease, and to avoid unnecessary damage and injury
to the leasehold estate, and also to avoid damage and wastage of other natural
resources not covered by this lease. All operations of Lessee, whether conducted
directly by Lessee or by operators or contractors, shall be at the sole cost
and expense of Lessee.

    It is expressly covenanted and agreed that Lessor does not grant Lessee or
any person dealing with Lessee any right to subject the property hereinabove
described, nor any leased substances, to any lien-rights for labor or
mechanic's liens, nor to any materialmen's liens, nor to any other lien for any
act, omission, neglect, or performance of Lessee or its agents, employees,
and contractors. In the event any one shall file any notice or claim of lien
against said property or any estate in said property, Lessee shall take all
necessary steps expeditiously to have such notice or claim released of record.
Lessee shall save Lessor harmless from any and all lien notices and claims
against said land arising from any act or neglect of Lessee and any contractor
or operator of Lessee in any operations on or relating to the hereinabove
described lands.

    Lessee shall not fence off or otherwise make inaccessible to livestock
lawfully on the surface of said premises any watering place without the written
consent of Lessor; provided, that Lessee shall not permit any livestock to come

available or capable of being made available for domestic use or irrigation. In
the operations of Lessee, Lessee shall comply with all laws and regulations for
control of water which might be

surface and underground waters as required by Chapter 14, Title 73, Utah Code
Annotated, 1953, as amended. Lessee shall comply with all valid laws and
regulations relating to prevention and suppression of fires, make all necessary
provisions for sanitary disposal of wastes, and in all operations connected with
said leasehold take appropriate measures for protection of human life and
prevention of injuries and disease.

        ARTICLE XIV. RIGHTS OF LESSOR FOR INSPECTIONS OF LEASEHOLD AND RECORDS

    Lessor, its officers, and agents have the right at all reasonable times 
to enter upon the leased lands and premises to inspect the conditions of the 
leasehold, the work done under the terms of this lease, and the production 
obtained from the leasehold, such entry and inspections to be done in such a 
manner as shall not unreasonably interfere with the lawful operations by the 
Lessee in performance of the terms and conditions of this lease.

    Lessor also shall have the right to examine all books and records
pertaining to operations under this lease whether such books and records are
located within a building on the leased premises or located in an office
elsewhere and to make copies and abstracts of such records if desired by Lessor.
Lessor, its officers, and agents shall have the right to post upon or within the
leasehold such notices deemed proper or expedient by Lessor.

    If Lessee maintains an office in another state or in a foreign country,
Lessee nevertheless shall maintain within the State of Utah proper and adequate
records relating to operations on this leasehold and also relating to production
of leased substances and payment of rentals and royalties. Lessee also shall
have a resident agent in the State of Utah to whom any and all notices may be
sent by Lessor and on whom process may be served. In the event of any change in
the address of Lessee's office in the State of Utah, Lessee shall promptly
furnish Lessor with written notice of such change of address within the State
of Utah. Examinations of records of Lessee by the Lessor shall be conducted at
reasonable times.

    In the event Lessee conducts core-drilling operations within the leasehold,
or by directional drilling from adjacent land, Lessor shall have a right of
inspection of core samples and any analysis made thereof and any assay;
provided, that any report obtained by Lessor of any core-drilling operations may
be declared confidential information by Lessee, in which event Lessor shall keep
such information in a separate confidential information file.  Such Information
shall not be disclosed to any competitor nor to any one except to a
representative of the Attorney General of the State of Utah until Lessee waives
confidentiality or upon surrender, expiration, or termination of this lease.

    After completion of any core drilling, Lessee shall notify Lessor; and
Lessee shall cause all core holes to be plugged or sealed as expeditiously as
possible after the need for keeping such core holes unplugged ceases, in
accordance with regulations and requirements of the Division of Oil, Gas, and
Mining.

           ARTICLE XV. OPERATIONS IN CONJUNCTION WITH MINING ON OTHER LANDS

    In the event Lessee, in the interest of economy in mining operations,
desires to conduct mining operations on or within the above-described lands in
conjunction with mining operations on or within any adjacent Federal, State, or
privately-owned land by

utilization of shafts, inclines, or tunnels within either the above-described
lands, or within adjacent lands, Lessee shall make application in writing to the
Board of State Lands & Forestry and submit with such application a detailed plan
of operations illustrating how leased substances mined from the above-
described lands can and will be mined, segregated, and separately accounted for
from leased substances mined from some adjacent land. No such operations shall
be conducted without written approval of the Board. Any approval granted by the
Board shall be conditioned upon proper segregation and proper accounting and
record keeping of leased substances mined from each property. Separate records
shall be required for accounting for leased substances mined from the above-
described lands.

    In the event Lessee desires to process or mill leased substances from the 
above-described land in conjunction with processing or milling of leased 
substances from adjacent or some other lands, whether such processing or 
milling is intended to be performed on the above-described land or on some 
other land, Lessee shall submit to the Board a written application detailing 
how the leased substances mined from the above-described lands shall be 
segregated and separately accounted for in computation of royalty payments 
from leased substances mined from other lands. Any Board approval for any 
such arrangements shall be conditioned upon segregation of leased substances 
produced from the above described lands from mineral substances produced from 
other lands with adequate safeguards to assure proper accounting for 
determination of royalty.

    If application is granted for either type of operation or for both, all
procedures for either production or milling of minerals shall be subjected to
examination by the Division of State Lands & Forestry and by the Division of
Oil, Gas, and Mining to determine whether either type of arrangement functions
satisfactorily without detriment to the State of Utah. If such inspection
results in an adverse report with recommendations for modification or
discontinuance of such operations, a copy of the report with recommendations
shall be submitted as expeditiously as possible to the Lessee. If any
objectionable condition is not promptly remedied to safeguard the rights of the
State as Lessor, the Board of State Lands & Forestry shall have the right to
order discontinuance of such arrangement; and failure to comply with such order
of the Board shall constitute a breach of this Lease Agreement.

              ARTICLE XVI. SPECIAL REQUIREMENTS IN EVENT OF STRIP-MINING

    In the event Lessee desires to conduct any strip-mining or open-pit mining
or operations which will materially disturb the surface of the above-described
lands or some portion thereof, at least sixty (60) days before commencing such
type of mining activities, Lessee shall submit to the Division of State Lands &
Forestry the proposed plan of operations together with a proposed plan of
surface rehabilitation in compliance with the Rules and Regulations adopted
thereunder.  A copy of such proposed plan of operations and proposed plan of
surface rehabilitation also shall be submitted to the Division of Oil, Gas, and
Mining.  No such operations shall be commenced until the Division of Oil, Gas,
and Mining approves the plan of operations and approves a program of
rehabilitation.  Security may be required of Lessee to assure appropriate
rehabilitation in accordance with the said statute and rules and regulations
adopted thereunder.

                             AMENDMENT TO LEASE AGREEMENT

                                       ML 20569



    WHEREAS, the State Land Board, acting in behalf of the State of Utah,
Lessor, and Joseph F. Costanza, Lessee, entered into that certain Metalliferous
Minerals Lease dated May 28, 1963, as amended by that certain agreement dated
November 5, 1984 ("ML 20569"); and

    WHEREAS, the School and Institutional Trust Lands Administration
(hereinafter referred to as "Lessee') is the successor in interest to the State
Land Board; and

    WHEREAS Summo USA Corporation (hereinafter referred to as "Lessee") is now
the Lessee of record and the record title owner as to ML 20569; and 

    WHEREAS, Lessor and Lessee desire to supplement certain terms, conditions 
and obligations under ML 20596.

    NOW THEREFORE, in consideration of the premises and other good and valuable
consideration, the receipt and sufficiency of which are hereby mutually
acknowledged, Lessor and Lessee do hereby agree as follows:

    1.   Lessor will extend the term of ML 20596 for ten (10) years from
January 1, 1995, and for so long thereafter as leased substances are being
produced in commercial quantities.

    2.   To maintain ML 20596 in force during such ten (10) year extension, 
Lessee shall pay to Lessor an annual rental of one dollar ($1.00) per acre, 
and for each fractional part of an acre, on or before January 1 of each year. 
Rental payments may be credited against actual production royalties only for 
the year in which they accrue.

    3. In furtherance of Lessee's obligation for diligent operations or
development activity under the terms of ML 20596, and to maintain ML 20596 in
force during such ten (10) year extension, Lessee shall also tender to Lessor an
additional payment of Seven Thousand Eight Hundred Seventy-five and No/100
dollars ($7,875.00), due annually on or before January 1 of each year beginning
January 1, 1996.  Such payment shall be considered evidence of Lessee's
commitment to diligent operations for the next ensuing year. Diligence payments
may be credited against actual production royalties only for the year in which
they accrue.

<PAGE>

    4.   Lessee shall pay Lessor a royalty of eight percent (8.0%) for
fissionable metalliferous minerals and four percent (4.0%) for non-fissionable
metalliferous minerals. The royalty shall be based on the gross value of the
ores produced from the leased lands and sold by the lessee under an arms-length
contract, except that if there is not an arms-length contract for the ore the
royalty shall be based on the gross value received by the lessee under an arms-
length contract for the processed product(s) produced from the leased lands less
actual processing and refining costs. Processing and refining deductions will
not include mining, transportation, administrative, or depreciation costs, or
deductions for property taxes. Should the processed products be sold under a
non-arms-length contract the royalty shall be based on the amount received under
the non-arms-length or the fair market value of the products whichever is
greater, less the allowable deductions as set forth above.

    5.   Lessor shall have the right to readjust any provision, term or
condition of ML 20596 at any time after January 1, 2005.

    6.   All terms, conditions and rights as to ML 20596 shall be subject to
current and all future State Statutes, Regulations and Rules governing the
management and use of school and institutional trust lands, and rules
promulgated by other governmental agencies, as appropriate.

    7.   This Amendment Agreement is supplemental to ML 20596 and does not
amend or supersede nor is it intended as an abrogation or waiver of any rights
Lessor may have under ML 20596, except those terms and conditions specifically
listed above.

    IN WITNESS WHEREOF, this Agreement is made and entered into this 15 day of
August, 1995.

                    ARTICLE I. MINERALS COVERED BY THIS LEASE

     This Mineral Lease covers the following-described leased mineral substances
with the boundaries of the above-described lands, to-wit:

     METALLIFEROUS MINERALS

     "Metalliferous Minerals" are herein defined to include any ore containing
any of the following minerals: Aluminum, Antimony, Arsenic, Beryllium, Bismuth,
Cadmium, Chromium, Cecium, Columbium, Cobalt, Copper, Flourspar, Gallium, Gold,
Germanium, Hafium, Iron, Indium, Lead, Mercury, Manganese, Molybdenum, Nickel,
Platinum, Group Metals, Radium, Selenium, Scandium, Silver, Rare Earth Metals,
Rhenium, Tantalium, Tin, Thorium, Tungsten, Thallium, Tellurium, Vanadium,
Uranium, Zinc, together with other minerals which are found in association with
said specified minerals in such a manner that they cannot be mined separately.

     In the event Lessee, or the operator or any contractor for Lessee, shall
discover within said lands some mineral or minerals other than the mineral or
leased substances covered by this lease, Lessee shall promptly notify the Lessor
of the kind or nature of such mineral or minerals not included in this lease.

        ARTICLE II. PRIMARY TERM AND POSSIBLE EXTENSION OF TERM OF LEASE

     This lease is granted for a primary term of TEN (10) years commencing on
the first day of January next succeeding the date hereinabove first written and
as long thereafter as the leased substances shall be produced in commercial
quantities from the above-described lands, on condition that Lessee shall
perform the terms and provisions required to be performed by Lessee including
payment of rents and royalties within the times required herein; provided
however, that it is expressly agreed that at the end of each period of ten (10)
years following the effective date of this lease, the State of Utah as Lessor
shall have the right to readjust the terms and conditions of this lease as may
then be determined to be in the best interest of the State of Utah as trustee-
owner of the mineral estate. In the event of failure or refusal of the Lessee to
accept and agree to the readjustment of the terms and conditions submitted by
Lessor at the end of such ten (10)-year period, such failure or refusal to
accept such readjustment of terms, conditions, or royalty shall operate to
forfeit any right to extension of the term of this Mineral Lease and terminate
this lease except for the rights of the State of Utah to recover any royalties
then owing the State and/or any damages for which Lessee may be liable. This
lease will not be extended beyond the end of the fortieth year except by the
production of the leased substances in commercial quantities from the leased
lands. If Lessee ceases production of leased substances in commercial quantities
this lease will terminate one (1) year from the date of last commercial
production, unless Lessee commences commercial production at least three (3)
months prior to the end of such year and such commercial production then
continues for at least six (6) months.

                  ARTICLE III. APPLICABLE LAWS AND REGULATIONS

regulations relating to safety, sanitation, and health whether under the
jurisdiction of the Division of Oil, Gas, and Mining with respect to operations
under this lease or under the jurisdiction of some other State agency.

                    ARTICLE IV. RIGHTS TO THE SURFACE ESTATE

     If the surface estate of all or some portion of the 
hereinabove-described lands is owned by the Lessor, Lessee shall be entitled 
to use reasonably and prudently such portions of the surface estate owned by 
Lessor as shall be reasonably necessary to explore and prospect for, mine, 
drill, remove, and dispose of the leased mineral substances, including 
permission to establish and maintain in a safe condition on the surface 
estate owned by Lessor, access roads, communication lines, tanks, pipelines, 
reservoirs, mills, processing plants, reduction works, dumps, and other 
essential structures, facilities, machinery, and equipment, reasonably 
necessary and expedient for the economic operation of the leasehold and in 
furtherance of production, treatment, and disposition of the leased 
substances under this lease. Such surface uses shall be exercised subject to 
the rights reserved to the State of Utah as provided in Article V hereof, and 
without unreasonable interference with the rights of any prior or subsequent 
lessee of the State of Utah under the program of multiple use. 

     If the surface estate of any portion of the described lands is not owned 
by the State of Utah, except for a reserved right of entry to the mineral 
estate or mineral estates, the Lessee may exercise such right of entry to the 
mineral estate covered by this lease, at the sole cost and expense of Lessee 
herein and without cost to the State of Utah. If any damage is caused 
directly or indirectly to the surface estate by the Lessee or by the 
contractor or operator for Lessee, Lessee shall make proper restitution and 
indemnify the surface owner or owners. Lessee also shall make proper 
rehabilitation as required by the Utah Mined Land Reclamation Act and as 
required by all lawful rules and regulations adopted thereunder.

     Lessor will require a bond to be posted or other security given to the
State to be filed with Lessor or any other State agency or officer in a
principal amount determined by Lessor to be adequate to assure appropriate
reclamation and restitution for any damage to the surface estate.

                ARTICLE V. EXCEPTIONS AND EXCLUSIONS FROM LEASE

     Lessor hereby excepts and reserves from the operation of this lease the
following rights and privileges:

     FIRST: The right to establish rights of way and easements on, through, 
or over the land above described, for utility corridors and for joint or 
joint and several uses, as may be necessary and appropriate for the 
management of the above-described lands and other lands of Lessor or lands 
administered by Lessor, and for the working of other deposits within said 
lands under mineral leases granted to others under the program of multiple 
use.

     SECOND: The right to issue mineral leases to other lessees covering 
minerals not included in this lease, under such terms and conditions which 
will not unreasonably interfere with operations under this lease in 
accordance with the principle of multiple use provided by law.

     THIRD: In the event Lessor owns the surface estate in said lands or
portions of said lands above described, Lessor retains the right to use, lease,
sell, or otherwise dispose of the surface estate in said lands or any part
thereof, under existing State laws or laws subsequently enacted, insofar as such
surface is not essential for the Lessee herein in exploration, prospecting for,
mining, drilling, removal, or disposal of the leased substances covered by this
lease, to the extent that such use, lease, or sale of the surface estate does
not unreasonably interfere with the rights granted to the Lessee herein. Lessor
shall notify Lessee herein of any such sale, lease, use, or other disposition of
the surface estate.

                  ARTICLE VI. PAYING OF RENTALS AND ROYALTIES

     For and in consideration of the leasehold rights granted to the Lessee, 
in addition to all other terms and conditions required to be performed by the 
Lessee, the Lessee hereby covenants and agrees with Lessor to pay rentals and 
royalties as follows:

     FIRST: Lessee agrees to pay Lessor as rental for the land covered by 
this lease the sum of One Dollar ($1.00) per acre and for each fractional 
part of an acre, each year in advance on or before January 1st of each year 
except the rental for the first year which has been paid with the application 
for this lease. All rentals paid shall be credited against actual Production 
Royalties for the lease year in which they shall accrue, but such rentals 
shall not be credited against the Minimum Royalties under subparagraph 
"Fourth" of this ARTICLE VI.

     SECOND: "Lessee shall pay lessor a production royalty on the basis of 8% in
the case of fissionable Metalliferous Minerals and 4% in the case of
non-fissionable Metalliferous Minerals of the market price, including all
bonuses and allowances received by Lessee, f.o.b. the nearest point of sale of
the first marketable product or products produced from the leased substances and
sold under a bonafide contract of sale, whether or not such product or products
are produced through chemical or mechanical treating or processing of the leased
substances raw material. It is expressly understood and agreed that none of
Lessee's mining or product cost, including but not limited, to material costs,
labor costs, overhead costs, distribution costs, or general and administrative
costs may be deducted from marketprice f.o.b. the point of sale in computing
Lessor's royalty. All such costs shall be entirely borne by Lessee and are
anticipated by the rate of royalty assigned in his agreement."

     THIRD: Payment of Production Royalty shall be made by Lessee to Lessor, 
as herein required, on or before the last day of the month next succeeding 
the month during which the minerals or leased substances shall have been 
shipped or sold or used. In connection with such payment of Production 
Royalty, the Lessee shall submit a certified statement of the production of 
all leased substances mined or extracted from the hereinabove-described 
lands, according to the foregoing royalty schedule together with such 
information required by the Board of State Lands & Forestry to verify 
production and disposition of mineral substances produced and disposed of 
from the leased premises.

                                                               Met. Min. - 1282d

                                       -5-

     FOURTH: Lessee may maintain this lease in force beyond the primary term 
of ten (10) years from the effective date of the original lease by paying 
Lessor, in addition to rentals and production royalties as hereinabove 
required, an annual minimum royalty of three (3) times the annual rental, 
providing the lessee is engaged in diligent operations, exploration, 
research, or development activity which is reasonably calculated to advance 
development or production of the mineral covered by the lease from the leased 
premises or lands pooled or unitized with or constituting an approved mining 
or drilling unit in respect to the leased premises.

     Said annual minimum royalty shall be paid each year in advance, commencing
with the eleventh year of the lease, along with the regular annual rental
required to be paid under the terms of this lease. Said rental per acre and said
Minimum Royalty shall be paid on each and every acre in this lease to extend
the term of this lease and to keep this lease in force and effect.

     Rentals and Minimum Royalties paid annually shall be credited against
actual Production Royalties for the year in which they accrue during the
original term, or any extension thereof; but annual rentals shall not be
credited against Minimum Royalties.

                      ARTICLE VII. MINERAL TITLE OF LESSOR

     Lessor claims title to the mineral estate covered by this lease. Lessor 
does not warrant title nor represent that no one will dispute the title 
asserted by Lessor. It is expressly agreed that Lessor shall not be liable to 
Lessee for any alleged deficiency in title to the mineral estate, nor shall 
Lessee or any assigns of the Lessee become entitled to any refund for any 
rentals, bonuses, or royalties paid under this lease.

                           ARTICLE VIII. WATER RIGHTS

     In the event Lessee shall initiate any water rights on the leased premises,
such right shall become an appurtenance to the leased premises; and upon
surrender, cancellation, or termination of this lease, Lessee or assigns of
Lessee shall assign and convey such water rights and any application for
appropriation of water to beneficial use relating to the land or the mineral
estate covered by this lease to Lessor.

     If the Lessee shall purchase or otherwise acquire any water rights on 
some other land and file with the State Engineer appropriate application for 
change of use onto the premises covered by this lease, the Lessor herein 
shall have an option for 45 days after the expiration, surrender, or 
termination of this lease to purchase said otherwise acquired water rights at 
the acquisition costs of the Lessee. Such option shall begin to run from the 
date of termination, surrender, or expiration of this lease or from the date 
when Lessee shall specify in writing the acquisition costs of such other 
water rights, whichever date is the later date. Unless Lessor accepts such 
written offer to convey such rights at the actual acquisition costs within 
said period of 45 days, Lessor shall be deemed to have rejected the offer. 
Upon payment of the said acquisition costs by the Lessor, Lessee herein shall 
assign and transfer such acquired water rights to the Lessor.

        ARTICLE IX.  WRITTEN CONSENT REQUIRED FOR ASSIGNMENT OR SUBLEASE

     Lessee shall not assign this lease nor any portion thereof, nor any rights
or privileges herein granted, without the prior written consent of Lessor. Nor

Lessee issue any sublease without the prior written consent of Lessor. Any
assignment of lease and any sublease issued without prior written consent of
Lessor shall be void ab initio.

     In the event Lessor shall approve an assignment of this lease or of any
part hereof, such assignment shall be subject to all of the terms, conditions,
and obligations of the Lessee herein set forth. All of the terms, covenants,
conditions, and obligations of the Lessee shall be binding upon the heirs,
executors, administrators, successors, and assigns of the Lessee. This provision
also shall apply to any sublease issued by Lessee and approved by Lessor.

                    ARTICLE X. OVERRIDING ROYALTY LIMITATION

     Neither the Lessee nor the assignee of Lessee shall create or grant any
overriding royalty except as permitted by law and by the Rules and Regulations
of the Board of State Lands & Forestry. Overriding royalty assignments shall not

                ARTICLE XI. SURRENDER OR RELINQUISHMENT OF LEASE

     Lessee may surrender this lease  for cancellation by Lessor as to all or
any part of the leased lands, but not for less than a quarter-quarter section or
surveyed lot, upon payment of all rentals, royalties, and other amounts then
due and owing to the Lessor, by filing with Lessor a written relinquishment. As
to rental, such relinquishment shall be effective on the date of filing, but
otherwise on the date of cancellation by the Lessor.

     ARTICLE XII. NOTICE OF COMMENCEMENT OF OPERATIONS, PLANS, PLATS, BOND

     Not less than sixty (60) days before commencement of exploration, drilling,
or mining operations, Lessee shall give written notice hereof to the Division
of State Lands & Forestry and the Division of Oil, Gas, and Mining, together
with a plan of operation and a topographic map showing every proposed shaft,
tunnel, open pit, drill site, and access road to be used. Lessor shall make an
assessment of such plan of operation and either endorse or stipulate changes in
Lessee's plan of operation, or request additional information within the sixty
(60) day notification period. Lessee shall not proceed with the execution of
any such plan of operation without first receiving the written approval of
Lessor. Lessee shall maintain at the mine office clear, accurate, and detailed
maps of all actual and planned operations on a scale of not more than 50 feet to
the inch, with points coordinated with public land surveys showing distance to
the nearest public survey monument or reestablished survey corner. Such maps and
plats shall be on tracing cloth or other material which is substantially
permanent and of which clear and distinct photo copies or blueprints can be
readily made without unreasonable delay. Such maps or plats shall show the
workings from time to time, as the same are extended. In the event that the
operations on the above-described leasehold are intended to be conducted in
conjunction with adjacent lands, whether Federal, State, or privately-owned
lands, the map and plats shall clearly show how the operations are to be
coordinated. All surveys shall be conducted by a licensed surveyor or engineer
qualified to practice in Utah. All such maps or plats shall be certified by the
surveyor or engineer

preparing the same. The State or any agency of the State of Utah, including the
Division of Oil, Gas, and Mining, shall be entitled to a true and correct copy
thereof, together with the proposed plans of operation.

     After Lessor receives notice of intent to commence mining operations, 
upon request of the Lessor, the Lessee shall furnish a bond with an approved 
corporate surety company authorized to transact business in the State of 
Utah, or such other security acceptable to the Lessor, in an amount to be 
determined by Lessor, after taking into account the value of the land and the 
amount of potential damage which likely will result from such proposed mining 
operations, and which bond or other security shall be conditioned upon 
payment of all rentals and royalties from the leasehold and other sums which 
may become payable to the Lessor, and to assure full compliance with the 
terms and conditions of this lease and compliance with all Rules and 
Regulations of the Board of State Lands & Forestry and all Rules and 
Regulations of any other State agency having jurisdiction over mining 
operations, and also conditioned upon payment of all damages to the surface 
and improvements thereon if this lease covers surface estate or some portion 
of the surface estate which has been sold or otherwise leased, and any damage 
caused by Lessee to any other lessee of the State of Utah with respect to 
said land. Such bond or other security furnished prior to commencement of 
development of the leasehold may be increased in such reasonable amounts as 
the Lessor may require after discovery of any of the leased substances.

     If the plan of mining development or mining operations includes 
core-drilling, the plan of operations shall disclose the locations of 
core-drilling operations.

    ARTICLE XIII. ALL OPERATIONS TO BE CONDUCTED IN A LAWFUL, PRUDENT MANNER

     Lessee shall conduct all operations under this lease in a lawful, 
prudent, and good workmanlike manner for the effective and safe production of 
the mineral substances covered by this lease, and to avoid unnecessary damage 
and injury to the leasehold estate, and also to avoid damage and wastage of 
other natural resources not covered by this lease. All operations of Lessee, 
whether conducted directly by Lessee or by operators or contractors, shall be 
at the sale cost and expense of Lessee.

     It is expressly covenanted and agreed that Lessor does not grant Lessee or
any person dealing with Lessee any right to subject the property hereinabove
described, nor any leased substances, to any lien-rights for labor or mechanic's
liens, nor to any materialmen's liens, nor to any other lien for any act,
omission, neglect, or performance of Lessee or its agents, employees, and
contractors. In the event any one shall file any notice or claim of lien against
said property or any estate in said property, Lessee shall take all necessary
steps expeditiously to have such notice or claim released of record. Lessee
shall save Lessor harmless from any and all lien notices and claims against said
land arising from any act or neglect of Lessee and any contractor or operator of
Lessee in any operations on or relating to the hereinabove described lands.

     Lessee shall not fence off or otherwise make inaccessible to livestock 
lawfully on the surface of said premises any watering place without the 
written consent of Lessor; provided, that Lessee shall not permit any 
livestock to come upon any portion of the leasehold to pollute any surface or 
subsurface water available or capable of being made available for domestic 
use or irrigation. In the operations of Lessee, Lessee shall comply with all 
laws and regulations for control of water which might be

                                       -8-

encountered or which might seep into any formation, to avoid pollution of
surface and underground waters as required by Chapter 14, Title 73, Utah Code
Annotated, 1953, as amended. Lessee shall comply with all valid laws and
regulations relating to prevention and suppression of fires, make all necessary
provisions for sanitary disposal of wastes, and in all operations connected with
said leasehold take appropriate measures for protection of human life and
prevention of injuries and disease.

     ARTICLE XIV. RIGHTS OF LESSOR FOR INSPECTIONS OF LEASEHOLD AND RECORDS

     Lessor, its officers, and agents have the right at all reasonable times to
enter upon the leased lands and premises to inspect the conditions of the
leasehold, the work done under the terms of this lease, and the production
obtained from the leasehold, such entry and inspections to be done in such a
manner as shall not unreasonably interfere with the lawful operations by the
Lessee in performance of the terms and conditions of this lease.

     Lessor also shall have the right to examine all books and records
pertaining to operations under this lease whether such books and records are
located within a building on the leased premises or located in an office
elsewhere and to make copies and abstracts of such records if desired by Lessor.
Lessor, its officers, and agents shall have the right to post upon or within the
leasehold such notices deemed proper or expedient by Lessor.

     If Lessee maintains an office in another State or in a foreign country,
Lessee nevertheless shall maintain within the State of Utah proper and adequate
records relating to operations on this leasehold and also relating to production
of leased substances and payment of rentals and royalties. Lessee also shall
have a resident agent in the State of Utah to whom any and all notices may be
sent by Lessor and on whom process may be served. In the event of any change in
the address of Lessee's office in the State of Utah, Lessee shall promptly
furnish Lessor with written notice of such change of address within the State of
Utah. Examinations of records of Lessee by the Lessor shall be conducted at
reasonable times.

     In the event Lessee conducts core-drilling operations within the leasehold,
or by directional drilling from adjacent land, Lessor shall have a right of
inspection of core samples and any analysis made thereof and any assay;
provided, that any report obtained by Lessor of any core-drilling operations
may be declared confidential information by Lessee, in which event Lessor shall
keep such information in a separate confidential information file. Such
information shall not be disclosed to any competitor nor to any one except to a
representative of the Attorney General of the State of Utah until Lessee
waives confidentiality or upon surrender, expiration, or termination of this
lease.

     After completion of any core drilling, Lessee shall notify Lessor; and 
Lessee shall cause all core holes to be plugged or sealed as expeditiously as 
possible after the need for keeping such core holes unplugged ceases, in 
accordance with regulations and requirements of the Division of Oil, Gas, and 
Mining.

        ARTICLE XV. OPERATIONS IN CONJUNCTION WITH MINING ON OTHER LANDS

     In the event Lessee, in the interest of economy in mining operations,
desires to conduct mining operations on or within the above-described lands in
conjunction with mining operations on or within any adjacent Federal, State, or
privately-owned land by


<PAGE>

                                                                 Met. Min. 1282d

                                       -9-

utilization of shafts, inclines, or tunnels within either the above-described
lands or within adjacent lands, Lessee shall make application in writing to the
Board of State Lands & Forestry and submit with such application a detailed
plan of operations illustrating how leased substances mined from the above-
described lands can and will be mined, segregated, and separately accounted
for from leased substances mined from some adjacent land. No such operations
shall be conducted without written approval of the Board. Any approval
granted by the Board shall be conditioned upon proper segregation and proper
accounting and record keeping of leased substances mined from each property.
Separate records shall be required for accounting for leased substances mined
from the above-described lands.

     In the event Lessee desires to process or mill leased substances from the
above-described land in conjunction with processing or milling of leased
substances from adjacent or some other lands, whether such processing or milling
is intended to be performed on the above-described land or on some other land,
Lessee shall submit to the Board a written application detailing how the leased
substances mined from the above-described lands shall be segregated and
separately accounted for in computation of royalty payments from leased
substances mined from other lands. Any Board approval for any such arrangements
shall be conditioned upon segregation of leased substances produced from the
above-described lands from mineral substances produced from other lands with
adequate safeguards to assure proper accounting for determination of royalty.

     If application is granted for either type of operation or for both, all 
procedures for either production or milling of minerals shall be subjected to 
examination by the Division of State Lands & Forestry and by the Division of 
Oil, Gas, and Mining to determine whether either type of arrangement 
functions satisfactorily without detriment to the State of Utah. If such 
inspection results in an adverse report with recommendations for modification 
or discontinuance of such operations, a copy of the report with 
recommendations shall be submitted as expeditiously as possible to the 
Lessee. If any objectionable condition is not promptly remedied to safeguard 
the rights of the State as Lessor, the Board of State Lands & Forestry shall 
have the right to order discontinuance of such arrangement; and failure to 
comply with such order of the Board shall constitute a breach of this Lease 
Agreement.

           ARTICLE XVI. SPECIAL REQUIREMENTS IN EVENT OF STRIP-MINING

     In the event Lessee desires to conduct any strip-mining or open-pit 
mining or operations which will materially disturb the surface of the 
above-described lands or some portion thereof, at least sixty (60) days 
before commencing such type of mining activities, Lessee shall submit to the 
Division of State Lands & Forestry the proposed plan of operations together 
with a proposed plan of surface rehabilitation in compliance with the Utah 
Mined Land Reclamation Act and in compliance with the Rules and Regulations 
adopted hereunder. A copy of such proposed plan of operations and proposed 
plan of surface rehabilitation also shall be submitted to the Division of 
Oil, Gas, and Mining. No such operations shall be commenced until the 
Division of Oil, Gas, and Mining approves the plan of operations and approves 
a program of rehabilitation. Security may be required of Lessee to assure 
appropriate rehabilitation in accordance with the said statute and rules and 
regulations adopted thereunder.

to grant a reasonable extension of time beyond the period of two (2) months 
for removal of any and all equipment which may be removed by Lessee or 
operator or contractor as herein provided. At the end of such period, Lessor 
may consider abandoned and lay claim to any or all equipment or stockpiles 
remaining on the premises.

     Upon expiration, surrender, forfeiture, or termination of this
lease or abandonment of the leasehold by Lessee, the Lessee shall cause to be

     NOW THEREFORE, in consideration of the premises and other good and valuable

acknowledged, Lessor and Lessee do hereby agree as follows:

     1. Lessor will extend the term of ML 17661 for ten (10) years from January
1, 1995, and for so long thereafter as leased substances are being produced in
commercial quantities.

     2. To maintain ML 17661 in force during such ten (10) year extension,
Lessee shall pay to Lessor an annual rental of one dollar ($1.00) per acre, and
for each fractional part of an acre, on or before January 1 of each year. Rental
payments may be credited against actual production royalties only for the year
in which they accrue.

     3. In furtherance of Lessee's obligation for diligent operations or 
development activity under the terms of ML 17661, and to maintain ML 17661 in 
force during such ten (10) year extension, Lessee shall also tender to Lessor

produced from the leased lands less actual processing and refining costs. 
Processing and refining deductions will not include mining, transportation, 
administrative, or depreciation costs, or deductions for property taxes.

allowable deductions as set forth above.

     5. Lessor shall have the right to readjust any provision, term or condition
of ML 17661 at any time after January 1, 2005.

               1.   For and in consideration of the mutual covenants and

<PAGE>

               2.     This MINERALS LEASE is conditioned upon LESSEE proceeding
diligently and with all reasonable dispatch to explore and develop minerals on
the LEASED PREMISES, and to seek to place the subject property in production.
with a minimum requirement that LESSEE cause to be drilled no less than 300 feet
of core hole or reverse circulation hole within the first 18 months of this
Mineral Lease.

               3.     LESSOR and LESSEE agrees to execute such additional
documents as are reasonable and necessary in recordable form, and amendment or
amendments to this MINERALS LEASE or any other documents which better describe
the LEASED PREMISES.

               4.     This MINERALS LEASE shall commence on the date first 
above set forth in this instrument, run thereafter for a primary term of six 
(6) years and continue thereafter as long as production royalties are being 
paid provided, however, that in the event production of minerals in 
commercial quantities occurred during the primary term and thereafter ceases 
because it is no longer commercially feasible to continue the production of 
minerals from the LEASED PREMISES, this MINERAL LEASE shall continue beyond 
the expiration of the primary term without the necessity of production of 
minerals and/or metals in commercial quantities as long as it is not 
commercially feasible to continue production and as long as LESSEE performs 
all the covenants it is obligated to perform hereunder including, but not 
limited to, the covenant to pay the minimum advance royalty hereinafter 
provided.

               5.     LESSEE shall pay LESSOR a royalty equal to the percentage
(hereinafter set forth) of the NET PROCEEDS (hereinafter defined) received for
all ores, mineral, and/or metals, mined and removed from the LEASED PREMISES and
processed and sold in any chemical, mineral or metallic form, hereinafter
referred to as the "PRODUCT."  The percent of the royalty shall be determined by
the amount of NET PROCEEDS per pound of PRODUCT sold during the calendar month.
The royalty percentage shall be two and one half percent (2.5%).  The term "NET
PROCEEDS" means the gross amount received by LESSEE, after deducting freight and
handling charges from the point of final treatment to the point of final sale.
The term MARKET VALUE of contained metals and/or minerals shall mean the average
of U.S. Producer or major Suppliers prices, as quoted in Metals Week and as
published in Engineering and Mining Journal (E&MJ) for the month in which the
metals and/or minerals are sold.

               6.     LESSEE shall prepare and maintain such records as are
reasonable necessary to calculate the royalty due LESSOR hereunder and LESSEE
shall, on written request of LESSOR, furnish copies of such records to LESSOR.

               7.     Commencing with the date of this Mineral Lease, and on 
each anniversary thereafter, LESSEE shall pay LESSOR an annual minimum 
advance royalty.  The amount of said royalty shall be seven hundred dollars 
($700.00) upon execution and $700.00 upon the first anniversary thereof, then 
$1400.00 on the 2nd anniversary, $2100.00 on the 3rd anniversary, and 
$2800.00 on the 4th and subsequent anniversaries so long as this lease shall 
remain in effect.  LESSEE shall be entitled to

                                        2

<PAGE>

credit this minimum advance royalty against the production royalty to which the
LESSOR is entitled as set forth above.

               8.     The following provisions shall be applicable to "WASTE
MATERIAL" which is defined as material mined or extracted from the LEASED
PREMISES which LESSEE in its sole discretion determines not to sell because of
its mineral content, and LESSEE'S determination shall be final and conclusive:

               8.a.   LESSOR agrees that WASTE MATERIAL may be mined or
otherwise extracted without obligation upon LESSEE to return same to the place
from which extracted.  At no time during the term of this MINERAL LEASE or at
any time thereafter shall LESSEE be required to remove any WASTE MATERIAL
deposited by LESSEE on the LEASED PREMISES, except as otherwise provided by
applicable governmental laws, rules and regulations, including those governing
toxic or hazardous waste, in full force and effect on or before the termination
of this MINERAL LEASE.

               8.b.   All WASTE MATERIAL on the LEASED PREMISES prior to
surrender or termination of this MINERALS LEASE shall be the property of LESSEE,
and LESSOR shall have no right, title or interest whatsoever therein and thereto
until this MINERAL LEASE is surrendered or terminated.

               9.     With respect to taxes on the LEASED PREMISES:

               9.a.   LESSEE agrees to pay all taxes levied and assessed against
any improvements placed on the LEASED PREMISES by LESSEE.

               9.b.   The relationship (in terms of percentage) which the total
royalty which LESSOR receives hereunder during a given taxing period bears to
the total NET PROCEEDS for the same period shall be established by dividing the
total royalty received by LESSOR by the total NET PROCEEDS. LESSOR agrees to pay
that established percentage and LESSEE agrees to pay the balance of such taxes,
assessments, or other governmental levies which are assessed, levied or imposed
on sales or production, as per paragraph 5. LESSEE shall not be obligated to pay
any taxes levied, imposed or assessed against, or measured by reference to
operations upon the LEASED PREMISES which are not conducted by or on behalf of
LESSEE under the terms of this MINERALS LEASE. In the event LESSOR fails to pay
when due any taxes, assessments or other governmental levy against the LEASED
PREMISES (which LESSOR is obligated to pay under this MINERALS LEASE) LESSEE
may, but shall not be obligated to, pay such taxes, assessments or levies,
together with any penalty that may be imposed for failure to pay such when due.
LESSOR agrees to reimburse LESSEE for any payments made for LESSOR hereunder,
together with interest at the rate of 10% per annum from the date such payment
is made by LESSEE, which reimbursement shall be made within ten (10) days after
LESSEE has given written notice to LESSOR that LESSEE has paid such taxes,
assessments or levies. LESSEE shall specify the amount of such taxes,
assessments or levies in its notice to LESSOR. IF


                                        3

<PAGE>

SUCH REIMBURSEMENT IS NOT MADE AS PROVIDED HEREIN, lessee SHALL HAVE THE 
RIGHT TO WITHHOLD PAYMENT OF AND RETAIN AS ITS SOLE PROPERTY ANY AND ALL 
ROYALTY (including the minimum advance royalty provided above) thereafter due 
and payable to LESSOR until the amount of royalty withheld equals the 
reimbursement due LESSEE.

               10.    LESSOR shall have the right to claim the depletion
allowance applicable to the royalty paid LESSOR hereunder.

               11.    With respect to liens, damages, liability and insurance:

               11.a.  LESSEE agrees to indemnify LESSOR against, and hold 
LESSOR harmless from any and all claims or liability for injury to or death 
of persons or for damages to property resulting from LESSEE'S operations 
hereunder. LESSEE further agrees to indemnify LESSOR against and hold LESSOR 
harmless from any and all claims or liability for materials or labor 
resulting from LESSEE'S operations hereunder on the LEASED PREMISES. LESSOR 
agrees to notify LESSEE of the existence of such claim as soon as it becomes 
known to LESSOR, and further to notifies LESSEE of the institution of any 
action, suit or legal proceeding on such claim as soon as the institution of 
such action, suit, or other proceedings become known to LESSOR and LESSEE is 
given the sole right to defend and/or settle any such claim with attorneys of 
its own selection.

               11.b.  LESSEE further agrees to maintain workman's compensation
as required by Utah State law.

               11.c.  If LESSOR shall fail to pay any and all amounts due
hereunder, or duly to satisfy and discharge any mortgage or lien on the LEASED
PREMISES, or shall suffer or permit any lien or encumbrance to be imposed upon
the LEASED PREMISES, LESSEE may, at its own option, but shall not be obligated
to, pay any or all unpaid amounts due and payable under, or satisfy and
discharge any such amount so paid or for payments and costs of paying,
satisfying and discharging any such mortgage, lien or encumbrance, by
withholding and retaining as its sole property from royalties (including the
monthly minimum advance royalty) due and payable hereunder the amounts paid by
LESSEE. In case of payment, discharge or satisfaction of a mortgage, lien or
encumbrance LESSEE shall have all the rights and remedies against LESSOR which
the mortgage or lien or the holder of such encumbrance had against the LESSOR
immediately prior to the time of such payment, satisfaction or discharge.

               12.    LESSOR, or their representative, at their sole risk and at
their sole cost and expense, and subject to such reasonable safety regulations
as may be prescribed by LESSEE, may have access to the LEASED PREMISES during
regular business hours solely for the purpose of inspection of LESSEE'S
operations on the LEASED PREMISES.

               13.    LESSEE will conduct its operations on the LEASED 
PREMISES in accordance with applicable governmental laws, rules and 
regulations LESSEE makes no express or implied warranty, covenant or 
agreement relating to the exploration, development, mining or other

                                        4

<PAGE>

operation of or upon the LEASED PREMISES or the marketing of any ore or mineral

execute, acknowledge and deliver to LESSEE, in recordable form, and amendment or
amendments to this MINERALS LEASE or any other documents which better describe

                    4.    This MINERALS LEASE shall commence on the date first
above set forth in this instrument, run thereafter for a primary term of six (6)
years and continue thereafter as long as minerals are being produced from the
LEASED PREMISES in commercial quantities, unless sooner terminated or
surrendered as hereinafter set forth; provided, however, that in the event
production of minerals in commercial quantities occurred during the primary term
and thereafter ceases because it is no longer commercially feasible to continue
the production of minerals from the LEASED PREMISES, this MINERAL LEASE shall
continue beyond the expiration of the primary term without the necessity of
production of minerals and/or metals in commercial quantities as long as it is
not commercially feasible to continue production and as long as LESSEE performs

mean the average of U.S. Producer or major Suppliers prices, as quoted in 
Metals Week and as published in Engineering and Mining Journal (E&MJ) for the 
month in which the metals and/or minerals are sold.

                                        3

                    6.    LESSEE shall pay all royalties previously reserved and
all royalties due and owing on the underlying leases and subleases with respect
to the LEASED PREMISES.

                    7.    LESSEE shall prepare and maintain such records as are
reasonably necessary to calculate the royalty due LESSOR hereunder and the
royalty due on the underlying leases and subleases. LESSEE shall, on written
request of LESSOR, furnish copies of such records to LESSOR.

                    8.    The following provisions shall be applicable to "WASTE
MATERIAL" which is defined as material mined or extracted from the LEASED
PREMISES which LESSEE in its sole discretion determines not to sell because of
its mineral content, and LESSEE'S determination shall be final and conclusive:

                    8.a.  LESSOR agrees that WASTE MATERIAL may be mined or
otherwise extracted without obligation upon LESSEE to replace the same. At no
time during the term of this MINERALS LEASE or at any time thereafter shall
LESSEE be required to remove any WASTE MATERIAL deposited by LESSEE on the
LEASED PREMISES, except as otherwise provided by applicable governmental laws,
rules and regulations in full force and effect on or before the termination of

against LESSEE on the LEASED PREMISES, and any improvements placed on the LEASED
PREMISES by LESSEE.

                    9.b.  The relationship (in terms of percentage) which the
total royalty which LESSOR receives hereunder during a given taxing period bears
to the total NET PROCEEDS for the same period shall be established by dividing
the total royalty received by LESSOR by the total NET PROCEEDS. LESSOR agrees to
pay that established percentage and LESSEE agrees to pay the balance of such
taxes, assessments, or other governmental levies which are assessed, levied or
imposed:

                    9.b.(l)   Against the LEASED PREMISES solely by reason of
LESSEE'S operations on the LEASED PREMISES.

                    9.b.(2)   Against the minerals in or on the LEASED PREMISES
in all unsevered state.

proceeds of mines taxes, if any, imposed for, resulting from or measured by
reference to the removal of ore and or minerals by the LESSEE.

                    9.c.  LESSEE shall not be obligated to pay any taxes 
levied, imposed or assessed against, or measured by reference to operations 
upon the LEASED PREMISES which are not conducted by or on behalf of LESSEE 
under the terms of this MINERALS LEASE. In the event LESSOR fails to pay when 
due any taxes, assessments or other governmental levy against the LEASED 
PREMISES (which LESSOR is obligated to pay under this MINERALS LEASE) LESSEE 
may, but shall not be obligated to, pay such taxes, assessments or levies, 
together with any penalty that may be imposed for failure to pay such when 
due. LESSOR agrees to reimburse LESSEE for any payments made for LESSOR 
hereunder, together with interest at the rate of 10% per annum from the date 
such payment is made by LESSEE, which reimbursement shall be made within ten 
(10) days after LESSEE has given written notice to LESSOR that LESSEE has 
paid such taxes, assessments or levies. LESSEE shall specify the amount of 
such taxes, assessments or levies in its notice to LESSOR. IF SUCH 
REIMBURSEMENT IS NOT MADE AS PROVIDED HEREIN, lessee SHALL HAVE THE RIGHT TO 
WITHHOLD PAYMENT OF AND RETAIN AS ITS SOLE

                                        5

provided above) thereafter due and payable to LESSOR until the amount of royalty
withheld equals the reimbursement due LESSEE.

                    10.   LESSOR shall have the right to claim the depletion
allowance applicable to the royalty paid LESSOR hereunder.

                    11.   With respect to liens, damages, liability and
insurance:

                    11.a. LESSEE agrees to indemnify LESSOR against, and hold
LESSOR harmless from any and all claims or liability for injury to or death of
persons or for damages to property other than the LEASED PREMISES, resulting
from LESSEE'S operations hereunder. LESSEE further agrees to indemnify LESSOR
against and hold LESSOR harmless from any and all claims or liability for
materials or labor resulting from LESSEE'S operations hereunder on the LEASED
PREMISES. LESSEE'S obligations hereunder shall not apply to any claim unless
LESSOR notify LESSEE of the existence of such claim as soon as it becomes known
to LESSOR, and further notifies LESSEE of the institution of any action, suit or
legal proceeding on such claim as soon as the institution of such action, suit,
or other proceedings become known to LESSOR and LESSEE is given the sole right
to defend and/or settle any such claim with attorneys of its own selection.

                    11.b. LESSEE further agrees to maintain workman's
compensation as required by Utah State law.

                    11.c. If LESSOR shall fail to pay any and all amounts due 
hereunder, or duly to satisfy and discharge any mortgage or lien on the 
LEASED PREMISES, or shall suffer or permit any lien or encumbrance to be 
imposed upon the LEASED PREMISES, LESSEE may, at its own option, but shall 
not be obligated to, pay any or all unpaid amounts due and payable under, or 
satisfy and discharge any such amount so paid or for payments and costs of 
paying, satisfying and discharging any such mortgage, lien or encumbrance, by 
withholding and retaining as its sole property from royalties (including the 
monthly minimum advance royalty) due and payable hereunder the amounts paid 
by LESSEE. In case of payment, discharge or satisfaction of a mortgage, lien 
or encumbrance LESSEE shall have all the rights and remedies against LESSOR 
which the

                                        6
<PAGE>


mortgage or lien or the holder of such encumbrance had against the LESSOR
immediately prior to the time of such payment, satisfaction or discharge. Upon
the request of LESSEE, LESSOR shall promptly make, execute, acknowledge and
deliver to LESSEE any and all instruments which LESSEE in its sole judgment

                             Containing 55.25 acres

    TO HAVE AND TO HOLD for a term of Sixteen (16) years, beginning as of
August 1, 1986, subject to any and all existing valid rights in said land and
subject also to the following terms and conditions. LESSOR and LESSEE enter into
this Special Use Lease Agreement for the purpose that LESSEE develop the land in
the manner hereinafter described and consistent with the principles and
objectives of land development expressed and implicit in the Enabling Act of
Utah (Act of July 16, 1894, Ch. 138, 28 Stat. 107) and Article X of the
Constitution of the State of Utah.

    1.   The subject tract shall be used by LESSEE for the purpose of a copper
ore processing plant. All improvements constructed on the subject tract shall
comply with the applicable provisions of the Uniform Building Code, Current
Edition, International Conference of Building Officials.

    2.   LESSEE shall pay, to the LESSOR as rental, for the subject tract the 
sum of $1000.00 per annum for the first year period of this lease. LESSOR 
acknowledges the receipt of $1000.00 which is payment of this rental for the 
year August 1, 1986 through July 31, 1987, plus the $50.00 application fee. 
Failure to pay the rental for a period of one month from the date such rent 
is due, and upon expiration of a written notice from LESSOR to LESSEE

    3.   LESSEE agrees that LESSOR shall have the right to adjust the annual
rentals as provided for in PARAGRAPH 2 at the end of each one (1) year period as
LESSOR shall deem to be reasonably necessary in the best interest of the State.

    LESSEE also agrees that at the end of five (5) years from the date of this
lease, and, if necessary, for each two (2) year period thereafter, LESSEE has
not developed the land as proposed in Paragraph (1), LESSEE shall then be
required to appear before the Board of State Lands and show that it has
exercised due diligence toward development of the land. If LESSEE fails to show
due diligence, then LESSEE agrees that LESSOR may at its option, terminate this
lease agreement as to any or all the land leased hereunder. In the event LESSOR
so terminates, LESSEE's interest in the land shall revert to the State.

    4.   LESSEE, in exercising the privileges granted by this lease, shall
comply with the provisions of all valid Federal, State, County, and Municipal
laws, ordinances, and regulations which are applicable to the subject tract and
operations covered by this lease.

    5.   The acquisition or assumption by another party under an agreement with
the LESSEE of any right or obligation of the LESSEE under this lease shall be
ineffective as to the LESSOR unless and until LESSOR shall have been notified of
such agreement and shall have recognized and approved the same in writing, and
in no case shall such recognition or approval: (i) operate to relieve the LESSEE
of the responsibilities or liabilities assumed to LESSOR as hereunder; or (ii)
be given unless such other party is acceptable to LESSOR as a lessee, and
assumes in writing all of the obligations of the LESSEE under the terms of this
lease as to the balance of the term thereof, or acquires the rights in trust as
security and subject to such conditions as be necessary for protection of the
public interests.

    6.   LESSEE shall be bound by all of the provisions, conditions, and
prohibitions of Chapter 14 of Title 73, Utah Code Annotated (1953) as amended.
No waste or by-products shall be discharged which contain any substance in
concentrations which will result in substantial harm to fish and wildlife, or to
human water supplies. Storage facilities for materials capable of causing water
pollution, if accidentally discharged, shall be located so as to prevent any
spillage into waters, or channels leading into water, that would result in
substantial harm to fish and wildlife or to human water supplies.

    7.   LESSEE shall take reasonable precautions to protect, in place, all
public land survey monuments and private property corners.

                                     EXHIBIT 10.8


                                     MINING LEASE


    THIS MINING LEASE made and entered into this 15th day of October, 1973, by
and between TINTIC URANIUM COMPANY, a Utah corporation, having its principal
office at 1112 Walker Bank Building, Salt Lake City, Utah (hereinafter
referred to as "Lessor") and CENTENNIAL DEVELOPMENT COMPANY, a Utah
corporation, whose principal office and place of business is located at 34
Century Park-Way, Salt Lake City, Utah (hereinafter referred to as "Lessee"),

                           W I T N E S S E T H :

    1.   LEASED PREMISES AND TERM. Lessor, in consideration of the royalties
hereinafter reserved and the performance of the duties and agreements
hereinafter expressed, does hereby lease to Lessee the mineral rights, exclusive
of oil and gas, and such surface rights as Lessor owns, to the following
described lands located in San Juan County, State of Utah, to wit:

         Lots One, Two, Three and Four of Section 1, in Township 31 South, of
         Range 25 East, of the Salt Lake Meridian.

which mineral rights and such surface rights are hereinafter referred to as the
"Leased Premises". It is the responsibility of the Lessee to obtain from the
surface owners, permission for surface use not clearly granted to Lessor.
Documents establishing Lessor's rights in the Leased Premises are attached
hereto and by reference are made a part hereof, to wit:

              1.   Conveyance and Agreement dated April 3, 1954, between G. 0. 
         Patterson and Edna L. Patterson, and T-U Uranium Company.

              2.   Agreement dated April 3, 1954, between G. 0. Patterson and
         Edna L. Patterson and T-U Uranium Company.

              3.   Conveyance, dated January 10, 1955, by T-U Uranium Company
         to Tintic Uranium Company.

              4.   Letter of opinion, dated October 28, 1959, by Ray, Rawlings,
         Jones & Henderson to Tintic Uranium Company.

    TO HAVE AND TO HOLD the Leased Premises unto the Lessee for mining
purposes, including prospecting, development, mining, extraction, benefication,
milling, processing, removal and sale of ores, metals and other materials of
commercial value, except oil and gas, and for all uses reasonably incidental
thereto, for a term commencing on the date hereof for a period of ten (10)
years, with the right of renewal for like TERMS THEREAFTER, upon written


<PAGE>

                                         -2-


notice to Lessor 90 days before the lease expiration date, as long as minimum
work requirements or better or minimum royalties or better, as specified below
are satisfied.

    2.   WORK REQUIREMENTS AND MINIMUM ROYALTIES. Lessee shall have two (2)
years from the date hereof to enter upon the Leased Premises to explore, drill,
conduct geological, geophysical and geochemical surveys, and otherwise
investigate the property, with the requirement that at least $12,000.00 be
expended on such work during the two-year period.

    Thereafter, Lessee shall continue diligently to explore, develop and mine
the Leased Premises, with an annual minimum expenditure of $3,000.00.
Expenditures to be credited against minimum work requirements shall include all
expenditures made by Lessee in connection with any and all investigations,
exploration, development, mining, extraction, benefication, milling, processing,
removal and sale of ores, metals-minerals and other materials within and from
the Leased Premises, except royalties paid to Lessor, income and franchise
taxes, home office expenses and supervisory salaries not directly related to
operations on the Leased Premises, the acquisition costs of depreciable items
and allowance for depletion.

    Beginning with the third year of the lease, Lessee shall pay a minimum
royalty of $250.00 per month. At the option of the Lessee, the minimum royalty
may be paid in an annual sum at the end of said lease year. Minimum royalties
paid shall be applied as a credit against actual royalties becoming due and
payable under this lease.

    3.   ROYALTIES. Lessor reserves to itself a royalty of six percent (6%) of
net smelter returns for all minerals, exclusive of uranium ores, thorium ores
and other ores containing fissionable materials, in recoverable amounts of 0.01%
or more.

    For the purposes of computation of the royalty hereunder, "net smelter
returns" shall mean all sums received by Lessee for ores or other products from
the Leased Premises, less all transportation and treatment charges not deducted
by the purchaser. In the event that the mill or smelter to which such ores or
products are delivered is owned, operated or controlled by Lessee or its
assigns, the charges of such mill or smelter shall not be greater than those of
comparable mills or smelters for milling or smelting similar materials. Haulage
from the mine to the mill site is to be part of the mining cost and not part of
the transportation cost.

    The term "net smelter return per ton", as used in this lease, shall mean, 
as to any shipment, the net smelter return for that shipment divided by the 
number of dry tons of ore in the shipment or the number of tons of ore 
yielding the concentrate in that shipment.

    On uranium ores, thorium ores, and ores containing fissionable materials, 
Lessee shall pay a twenty-five percent (25%) royalty or a twenty-five percent 
(25%)

<PAGE>

                                         -3-


net profit, as the case may be, from such ores sold or marketed, to the Grantors
or their assigns of the Conveyance and Agreement dated April 3, 1954, and the
Agreement dated April 3, 1954, copies of both of which are attached hereto and
by reference made a part hereof. A six percent (6%) royalty shall be paid to
Lessor on the proceeds from the sale of uranium ore, thorium ore, and ores
containing fissionable materials, containing a recoverable 0.01% or more of U3O8
or other fissionable materials, free of all development, mining and operating
costs.

    4.   ORES FROM THE LEASED PREMISES. Ores from the Leased Premises shall not
be co-mingled with ores from other operations without permission of Lessor.
Engineering, sampling and assaying procedures used in the determination of
grades and tonnages shall be established by agreement between Lessor and Lessee.

    5.   PAYMENT OF AND REPORTS RELATING TO ROYALTIES. Before the end of each
month following a month in which any net smelter returns or other proceeds have
been received, or as soon thereafter as possible, Lessee shall pay the royalties
due hereunder and furnish to Lessor a report of the net smelter returns or other
proceeds received, which report shall be accompanied by copies of the mill or
smelter settlement sheets.

    6.   REPORTS TO LESSOR. Lessee shall furnish to Lessor within thirty (30)
days after the end of each calendar quarter, while this lease is in force:

              a.   A report describing Lessee's operations or activities on the
         Leased Premises for the quarterly period.

              b.   Copies of the results of geological, geophysical and
         geochemical surveys including maps, drill logs, and assays pertaining
         thereto.

              c.   Copies of mine maps showing the current status of mine
         workings on the Leased Premises.

              d.   In all drilling and sampling on the Leased Premises, the
         Lessee shall check for the presence and content of uranium, vanadium,
         thorium, and other fissionable materials, regardless of whether or not
         such material is mined and sold. Assay and sampling data on these
         materials shall be included in the quarterly reports.

    7.   INSPECTION BY LESSOR. Lessee shall permit duly authorized
representatives of Lessor at all reasonable times to enter into the workings in
the Leased Premises for the purpose of examining, inspecting, surveying or
taking such samples as such representatives may desire and for the purpose of
ascertaining whether the terms and conditions of this lease are being performed
by Lessee. Lessee's agent may accompany such representative of Lessor, but such
representative shall enter upon the premises


<PAGE>

                                         -4-


at his own risk. Lessor or its representatives authorized in writing, shall at

occupational disease compensation insurance covering all of Lessee's employees,
and Lessee shall pay any taxes required and/or make any deductions required
under the Federal Social Security Act and/or the Utah Employment Security Act
for which Lessee may become obligated and shall comply with all Utah laws, rules
and regulations or any governmental authority affecting Lessee's operations on
the Leased Premises and shall furnish to Lessor evidence of such compliance.

    9.   INSURANCE. Lessee will maintain public liability and property damage
insurance, with an endorsement in favor of Lessor, covering the working of the

less than $25,000 for property damage.

    10.  POSTING ON LEASED PREMISES. The Lessee shall forthwith post and
thereafter keep posted in conspicuous places on the Leased Premises as many
written notices as may be necessary to adequately notify all persons who may
come within or upon the Leased Premises that the same are held by Lessee under
lease from Lessor and that Lessee, and not Lessor, is liable for the payment of
all labor performed and supplies and/or materials furnished to or used by Lessee

<PAGE>

                                         -5-


thereof, without the written consent of the Lessor, which consent shall not

hereto to take or hold said premises, or any part thereof, under any pretense
whatsoever.

    13.  PROPER OPERATIONS REQUIRED. Lessee shall conduct all operations and
work on the Leased Premises in good miner-like fashion and in such a manner as
to develop the premises for the realization of the maximum economical return
therefrom and shall comply with all of the applicable mining laws and
regulations of federal, state and local authorities.

    14.  TAX PAYMENTS.

         a.   Lessor's Taxes. Lessor shall pay all Federal, state and county
    taxes of any kind assessed against it on account of the receipt of
    royalties paid to it by Lessee hereunder.

         b.   Personal Property Tax. Lessee shall pay all state and county
    taxes assessed to it or to Lessor upon any improvements, machinery,
    equipment, tools, supplies and other property placed in or upon the Leased
    Premises by Lessee.

         c.   Property Tax. Lessee shall pay all state and county property tax
    assessments upon the Leased Premises, except as provided in Paragraph 13e
    hereof.

         d.   Severence Tax. "Severence" or "Production" taxes, if any, shall
    be prorated among and shall be paid by Lessee and Lessor in proportion to
    their respective participation in the proceeds thereof. The words
    "severence" or "production" taxes, as used herein, shall not be construed
    as including the tax referred to in Paragraph 13e or any tax resulting from
    a valuation based upon "net annual proceeds", nor the "mining occupation
    tax" referred to in Paragraph 13f.

         e.   Net Proceeds Tax. Taxes resulting from assessed valuation of the
    Leased Premises based upon "net annual proceeds", as provided in Section
    59-5-57, U.C.A. 1953, as amended, or any valuation method which may be
    substituted therefor, shall, except as otherwise provided in this
    paragraph, be prorated among and be paid by Lessee and Lessor in proportion
    to their respective participation in such "net annual proceeds".

         If for any calendar year after the termination of this lease (including
    the calendar year during which the lease is terminated) the assessed
    valuation of the Leased Premises based upon "net annual proceeds", shall
    exceed the assessed valuation which would otherwise have resulted




<PAGE>

                                         -6-


    but for "net annual proceeds" from Lessee's operations conducted upon this
    lease, then notwithstanding the termination of this lease, any additional
    taxes which result from such difference (increase) in assessed valuation
    shall be prorated among and shall be paid by Lessee and Lessor in
    proportion to their respective participation in such "net annual proceeds"
    which resulted in such increased valuation.

         f.   Mining Occupation Tax. Lessee shall be solely responsible for and
    agrees to pay any operations conducted under this lease.

    15.  TERMINATION BY LESSOR FOR CAUSE. If there shall be a violation by 
Lessee of any covenant or agreement herein contained, and Lessor shall send 
by registered mail to Lessee written notice specifying such violation and 
demanding possession of the premises covered by the Lease, and if at the 
expiration of 90 days after the date of mailing said notice of demand, the 
violation still continues, the term of this lease shall then at the option of 
Lessor terminate and expire and the leasehold rights of Lessee in the Leased 
Premises shall become forfeited, and this agreement shall be terminated in 
its entirety; and without further demand or notice, Lessor, by its agents or 
attorneys, may enter upon and into the Leased Premises and dispossess all 
persons occupying the same, with or without force, and with or without 
process of law, or at Lessor's option, Lessee and all persons found in 
occupation of such leased premises may be proceeded against as guilty of 
unlawful detainer. Failure of Lessor to exercise for any length of time any 
right of forfeiture for such cause shall in no event operate as a waiver of 
such right of forfeiture for such cause still continuing, or for any 
reoccurrence thereof or for any different cause.

    16.  SURRENDER OF PREMISES ON TERMINATION. Lessee will deliver to Lessor
the premises leased herein, with the appurtenances and improvements, in good
order and condition, reasonable wear and tear and damage by natural causes and
the mining operations herein authorized except, without demand or further
notice, on the last day of the term hereof, or of any extended term, or at any
time previous upon termination hereof, provided however:

         a.   BROKEN ORES. That all broken ores on or in the leased premises
    not shipped prior to such expiration or earlier termination may be removed
    by Lessee within 90 days after termination and accounted for as herein
    provided as if shipped and sold prior to termination, but if not so removed
    within said 90-day period such ores shall become the property of Lessor.

         b.   TRACK, PIPE, ETC. All tracks, pipe and ventilating tubing on or
    in the leased premises shall remain in place at the termination of the
    lease and become the property of Lessor.



<PAGE>

                                         -7-


         c.   REMOVAL OF EQUIPMENT. Upon termination of this lease and
    agreement, Lessee shall have the right, within 120 days from the date of
    such termination, to remove from the Leased Premises and sell sufficient
    fixtures and equipment (other than track, pipe and ventilating tubing)
    constructed or installed by it either on the surface or underground and not
    necessary for access to shafts, main levels and adits and main haulageways
    as will fully reimburse it for any undepreciated portion of the cost of
    such fixtures and equipment, provided that Lessor shall have the option to
    purchase, at as favorable a price and upon as favorable terms as can be
    obtained by Lessee from any other person, by giving Lessee written notice
    of its election to purchase such fixtures or equipment within 30 days after
    the date of such termination. All such fixtures and equipment not required
    to be disposed of to so reimburse Lessee and any such equipment remaining
    on the Leased Premises 120 days after the date of termination of the lease
    shall become the property of Lessor.

    17.  DELAY DUE TO CAUSES BEYOND CONTROL OF LESSEE. If Lessee shall be 
delayed, or interrupted in, or prevented from, performing its obligations as 
herein provided, by acts of God, fires, floods, strikes, insurrection or mob 
violence, injunction, regulations or orders or requirements of government, 
then and in all such cases Lessee shall for the time being, and without 
liability, be excused from performance of its obligations as herein provided, 
for the period of such prevention, delay or interruption; and all provisions 
of this lease and agreement shall again come into full force and effect 
immediately upon the termination of the period of prevention, delay or 
disability resulting from any of the causes aforesaid.

    18.  TERMINATION BY LESSEE. Notwithstanding anything herein to the
contrary, continuance of this lease and agreement shall be optional with Lessee,
and no penalty shall accrue or be asserted against Lessee by reason of
termination by Lessee or for failure thereafter to perform any of the
conditions, terms and agreements hereof; and Lessee may terminate this lease and
agreement at any time upon giving to Lessor 60 days written notice of intention
to terminate. Thereupon any liability of Lessee hereunder shall immediately
cease and terminate, except liability on account of any obligation arising out
of its operations in the Leased Premises incurred and owing at the time of such
termination.

    19.  MANNER OF GIVING NOTICE. Any written notice or other writing
contemplated herein shall be sufficiently served when the same has been

rents, royalties, and any other financial consideration paid or required to 
be paid by Lessee, and the terms and conditions to be performed by Lessee as 
hereinafter set forth, does hereby GRANT AND LEASE to the Lessee the

     TOWNSHIP 30 SOUTH, RANGE 26 EAST, SLB&M.
     Section 32: W 1/2

     This Mineral Lease is granted for and in consideration of and subject to
all of the terms, provisions, and conditions hereinafter set forth:

<PAGE>




                                       -2-

                    ARTICLE I. MINERALS COVERED BY THIS LEASE

     This Mineral Lease covers the following-described leased mineral substances
with the boundaries of the above-described lands, to-wit:

     METALLIFEROUS MINERALS

     "Metalliferous Minerals" are herein defined to include any ore containing
any of the following minerals: Aluminum, Antimony, Arsenic, Beryllium, Bismuth,
Cadmium, Chromium, Cecium, Columbium, Cobalt, Copper, Flourspar, Gallium, Gold,
Germanium, Hafium, Iron, Indium, Lead, Mercury, Manganese, Molybdenum, Nickel,
Platinum, Group Metals, Radium, Selenium, Scandium, Silver, Rare Earth Metals,
Rhenium, Tantalium, Tin, Thorium, Tungsten, Thallium, Tellurium, Vanadium,
Uranium, Zinc, together with other minerals which are found in association with
said specified minerals in such a manner that they cannot be mined separately.

     In the event Lessee, or the operator or any contractor for Lessee, shall
discover within said lands some mineral or minerals other than the mineral or
leased substances covered by this lease, Lessee shall promptly notify the Lessor
of the kind or nature of such mineral or minerals not included in this lease.

        ARTICLE II. PRIMARY TERM AND POSSIBLE EXTENSION OF TERM OF LEASE

     This lease is granted for a primary term of TEN (10) years commencing on
the first day of the month following the date hereinabove first written and as
long thereafter as the leased substances shall be produced in commercial
quantities from the abovedescribed lands, on condition that Lessee shall perform
the terms and provisions required to be performed by Lessee including payment of
rents and royalties within the times required herein; provided however, that it
is expressly agreed that at the end of each period of ten (10) years following
the effective date of this lease, the State of Utah as Lessor shall have the
right to readjust the terms and conditions of this lease as may then be
determined to be in the best interest of the State of Utah as trustee-owner of
the mineral estate. In the event of failure or refusal of the Lessee to accept
and agree to the readjustment of the terms and conditions submitted by Lessor at
the end of such ten (10)-year period, such failure or refusal to accept such
readjustment of terms, conditions, or royalty shall operate to forfeit any right
to extension of the term of this Mineral Lease and terminate this lease except
for the rights of the State of Utah to recover any royalties then owing the
State and/or any damages for which Lessee may be liable. This lease will not be
extended beyond the end of the twentieth year except by the production of the
leased substances in commercial quantities from the leased lands. If Lessee
ceases production of leased substances in commercial quantities this lease will
terminate one (1) year from the date of last commercial production, unless
Lessee commences commercial production at least three (3) months prior to the
end of such year and such commercial production then continues for at least six
(6) months.

                  ARTICLE III.  APPLICABLE LAWS AND REGULATIONS

     This lease is issued pursuant to the provisions of Title 65, Utah Code
Annotated, 1953, as amended, and subject to all valid Rules and Regulations and
requirements adopted by the Board of State Lands & Forestry, and of the Board of
Oil, Gas, and Mining, applicable to the subject matter of this lease, together
with all requirements of the Utah Mined Land Reclamation Act, all requirements
of the State Antiquities Act, Title 63, Chapter 18, and all valid rules and
regulations relating to safety, sanitation, and health whether under the
jurisdiction of the Division of Oil, Gas, and Mining with respect to operations
under this lease or under the jurisdiction of some other State agency.

                    ARTICLE IV.  RIGHTS TO THE SURFACE ESTATE

     If the surface estate of all or some portion of the hereinabove-described
lands is owned by the Lessor, Lessee shall be entitled to use reasonably and
prudently such portions of the surface estate owned by Lessor as shall be
reasonably necessary to explore and prospect for, mine, drill, remove, and
dispose of the leased mineral substances, including permission to establish and
maintain in a safe condition on the surface estate owned by Lessor, access
roads, communication lines, tanks, pipelines, reservoirs, mills, processing
plants, reduction works, dumps, and other essential structures, facilities,
machinery, and equipment, reasonably necessary and expedient for the economic
operation of the leasehold and in furtherance of production, treatment, and
disposition of the leased substances under this lease. Such surface uses shall
be exercised subject to the rights reserved to the State of Utah as provided in
Article V hereof, and without unreasonable interference with the rights of any
prior or subsequent lessee of the State of Utah under the program of multiple
use.

     If the surface estate of any portion of the described lands is not owned by
the State of Utah, except for a reserved right of entry to the mineral estate or
mineral estates, the Lessee may exercise such right of entry to the mineral
estate covered by this lease, at the sole cost and expense of Lessee herein and
without cost to the State of Utah. If any damage is caused directly or
indirectly to the surface estate by the Lessee or by the contractor or operator
for Lessee, Lessee shall make proper restitution and indemnify the surface owner
or owners. Lessee also shall make proper rehabilitation as required by the Utah
Mined Land Reclamation Act and as required by all lawful rules and regulations
adopted thereunder.

     Lessor will require a bond to be posted or other security given to the
State to be filed with Lessor or any other State agency or officer in a
principal amount determined by Lessor to be adequate to assure appropriate
reclamation and restitution for any damage to the surface estate.

                 ARTICLE V. EXCEPTIONS AND EXCLUSIONS FROM LEASE

     Lessor hereby excepts and reserves from the operation of this lease the
following rights and privileges:

     FIRST: The right to establish rights of way and easements on, through, or
over the land above described, for utility corridors and for joint or joint and
several uses, as may be necessary and appropriate for the management of the
above-described lands and other lands of Lessor or lands administered by Lessor,
and for the working of other deposits within said lands under mineral leases
granted to others under the program of multiple use.

     SECOND: The right to issue mineral leases to other lessees covering
minerals not included in this lease, under such terms and conditions which will
not unreasonably interfere with operations under this lease in accordance with
the principle of multiple use provided by law.

     THIRD: In the event Lessor owns the surface estate in said lands or
portions of said lands above described, Lessor retains the right to use, lease,
sell, or otherwise dispose of the surface estate in said lands or any part
thereof, under existing State laws or laws subsequently enacted, insofar as such
surface is not essential for the Lessee herein in exploration, prospecting for,
mining, drilling, removal, or disposal of the leased substances covered by this
lease, to the extent that such use, lease, or sale of the surface estate does
not unreasonably interfere with the rights granted to the Lessee herein. Lessor
shall notify Lessee herein of any such sale, lease, use, or other disposition of
the surface estate.

                  ARTICLE VI. PAYMENT OF RENTALS AND ROYALTIES

     For and in consideration of the leasehold rights granted to the Lessee, in
addition to all other terms and conditions required to be performed by the
Lessee, the Lessee hereby covenants and agrees with Lessor to pay rentals and
royalties as follows:

     FIRST: Lessee agrees to pay Lessor as rental for the land covered by this
lease the sum of One Dollar ($1.00) per acre and for each fractional part of an
acre, each year in advance on or before the first day of the month following the
anniversary date of this lease, except the rental for the first year which has
been paid with the application for this lease. All rentals paid shall be
credited against actual Production Royalties for the lease year in which they
shall accrue, but such rentals shall not be credited against the Minimum
Royalties under subparagraph "Fourth" of this ARTICLE VI.

     SECOND: Lessee shall pay lessor a royalty of eight percent for fissionable
metalliferous minerals and four percent for non-fissionable metalliferous
minerals. The royalty shall be based on the gross value of the ores produced
from the leased lands and sold by the lessee under an arms-length contract,
except that if there is not an arms-length contract for the ore the royalty
shall be based on the gross value received by the lessee under an arms-length
contract for the processed product(s) produced from the leased lands less actual
processing and refining costs. Processing and refining deductions will not
include mining, administrative, or depreciation costs, or deductions for
property taxes. Should the processed products be sold under a non-arms-length
contract the royalty shall be based on the amount received under the
non-arms-length contract or the fair market value of the products whichever is
greater, less the allowable deductions as set forth above.

<PAGE>


                                       -5-

     THIRD: Payment of Production Royalty shall be made by Lessee to Lessor, as
herein required, on or before the last day of the month next succeeding the
month during which the minerals or leased substances shall have been shipped or
sold or used. In connection with such payment of Production Royalty, the Lessee
shall submit a certified statement of the production of all leased substances
mined or extracted from the hereinabove-described lands, according to the
foregoing royalty schedule together with such information required by the Board
of State Lands & Forestry to verify production and disposition of mineral
substances produced and disposed of from the leased premises.

     FOURTH: Lessee may maintain this lease in force beyond the primary term of
ten (10) years from the effective date of the lease by paying Lessor, in
addition to rentals and production royalties as hereinabove required, an annual
minimum royalty of three (3) times the annual rental, providing the lessee is
engaged in diligent operations, exploration, research, or development activity
which is reasonably calculated to advance development or production of the
mineral covered by the lease from the leased premises or lands pooled or
unitized with or constituting an approved mining or drilling unit in respect to
the leased premises.

     Said annual minimum royalty shall be paid each year in advance, commencing
with the eleventh year of the lease, along with the regular annual rental
required to be paid under the terms of this lease. Said rental per acre and 
said Minimum Royalty shall be paid on each and every acre in this lease to
extend the term of this lease and to keep this lease in force and effect.

     Rentals and Minimum Royalties paid annually shall be credited against
actual Production Royalties for the year in which they accrue during the
original term, or any extension thereof, but annual rentals shall not be
credited against Minimum Royalties.

                      ARTICLE VII. MINERAL TITLE OF LESSOR

     Lessor claims title to the mineral estate covered by this lease. Lessor
does not warrant title nor represent that no one will dispute the title asserted
by Lessor. It is expressly agreed that Lessor shall not be liable to Lessee for
any alleged deficiency in title to the mineral estate, nor shall Lessee or any
assigns of the Lessee become entitled to any refund for any rentals, bonuses, or
royalties paid under this lease.

                           ARTICLE VIII. WATER RIGHTS

     In the event Lessee shall initiate any water rights on the leased premises,
such right shall become an appurtenance to the leased premises; and upon
surrender, cancellation, or termination of this lease, Lessee or assigns of
Lessee shall assign and convey such water rights and any application for
appropriation of water to beneficial use relating to the land or the mineral
estate covered by this lease to Lessor.

<PAGE>

                                                             
                                       -6-

     If the Lessee shall purchase or otherwise acquire any water rights on some
other land and file with the State Engineer appropriate application for change
of use onto the premises covered by this lease, the Lessor herein shall have an
option for 45 days after the expiration, surrender, or termination of this lease
to purchase said otherwise acquired water rights at the acquisition costs of the
Lessee. Such option shall begin to run from the date of termination, surrender,
or expiration of this lease or from the date when Lessee shall specify in
writing the acquisition costs of such other water rights, whichever date is the
later date. Unless Lessor accepts such written offer to convey such rights at
the actual acquisition costs within said period of 45 days, Lessor shall be
deemed to have rejected the offer. Upon payment of the said acquisition costs by
the Lessor, Lessee herein shall assign and transfer such acquired water rights
to the Lessor.

         ARTICLE IX. WRITTEN CONSENT REQUIRED FOR ASSIGNMENT OR SUBLEASE

     Lessee shall not assign this lease nor any portion thereof, nor any rights
or privileges herein granted, without the prior written consent of Lessor. Nor
shall the Lessee issue any sublease without the prior written consent of Lessor.
Any assignment of lease and any sublease issued without prior written
consent of Lessor shall be void ab initio.

     In the event Lessor shall approve an assignment of this lease or of any 
part hereof, such assignment shall be subject to all of the terms, 
conditions, and obligations of the Lessee herein set forth. All of the terms, 
covenants, conditions, and obligations of the Lessee shall be binding upon 
the heirs, executors, administrators, successors, and assigns of the Lessee. 
This provision also shall apply to any sublease issued by Lessee and approved 
by Lessor.

                     ARTICLE X. OVERRIDING ROYALTY LOCATION

     Neither the Lessee nor the assignee of Lessee shall create or grant any
overriding royalty except as permitted by law and by the Rules and Regulations
of the Board of State Lands & Forestry. Overriding royalty assignments shall not
become effective, even if otherwise valid, until filed with the Lessor.

                ARTICLE XI. SURRENDER OR RELINQUISHMENT OF LEASE

     Lessee may surrender this lease for cancellation by Lessor as to all or any
part of the leased lands, but not for less than a quarter-quarter section or
surveyed lot, upon payment of all rentals, royalties, and other amounts then due
and owing to the Lessor, by filing with Lessor a written relinquishment. As to
rental, such relinquishment shall be effective on the date of filing, but
otherwise on the date of cancellation by the Lessor.

      ARTICLE XII. NOTICE OF COMMENCEMENT OF OPERATIONS, PLANS, PLATS, BOND

     Not less than sixty (60) days before commencement of exploration, 
drilling, or mining operations, Lessee shall give written notice hereof to the 
Division of State Lands & Forestry and the Division of Oil, Gas, and Mining, 
together with a plan of operation and a topographic map showing every 
proposed shaft, tunnel, open pit, drill site, and access road to be used. 
Lessor shall make an assessment of such plan of operation and either endorse 
or stipulate changes in Lessee's plan of operation, or request additional 
information within the sixty (60) day notification period. Lessee shall not 
proceed with the execution of any such plan of operation without first 
receiving the written approval of Lessor. Lessee shall maintain at the mine 
office clear, accurate, and detailed maps of all actual and planned 
operations on a scale of not more than 50 feet to the inch, with points 
coordinated with public land surveys showing distance to the nearest public 
survey monument or reestablished survey corner. Such maps and plats shall be 
on tracing cloth or other material which is substantially permanent and of 
which clear and distinct photo copies or blueprints can be readily made 
without unreasonable delay. Such maps or plats shall show the workings from 
time to time, as the same are extended. In the event that the operations on 
the above-described leasehold are intended to be conducted in conjunction 
with adjacent lands, whether Federal, State, or privately-owned lands, the 
map and plats shall clearly show how the operations are to be coordinated. All 
surveys shall be conducted by a licensed surveyor or engineer qualified to 
practice in Utah. All such maps or plats shall be certified by the surveyor 
or engineer preparing the same. The State or any agency of the State of Utah, 
including the Division of Oil, Gas, and Mining, shall be entitled to a true 
and correct copy thereof, together with the proposed plans of operation.

     After Lessor receives notice of intent to commence mining operations, 
upon request of the Lessor, the Lessee shall furnish a bond with an 
approved corporate surety company authorized to transact business in the 
State of Utah, or such other security acceptable to the Lessor, in an amount 
to be determined by Lessor, after taking into account the value of the land 
and the amount of potential damage which likely will result from such 
proposed mining operations, and which bond or other security shall be 
conditioned upon payment of all rentals and royalties from the leasehold and 
other sums which may become payable to the Lessor, and to assure full 
compliance with the terms and conditions of this lease and compliance with 
all Rules and Regulations of the Board of State Lands & Forestry and all 
Rules and Regulations of any other State agency having jurisdiction over 
mining operations, and also conditioned upon payment of all damages to the 
surface and improvements thereon if this lease covers surface estate or some 
portion of the surface estate which has been sold or otherwise leased, and 
any damage caused by Lessee to any other lessee of the State of Utah with 
respect to said land. Such bond or other security furnished prior to 
commencement of development of the leasehold may be increased in such 
reasonable amounts as the Lessor may require after discovery of any of the 
leased substances.

     If the plan of mining development or mining operations includes
core-drilling, the plan of operations shall disclose the locations of
core-drilling operations.

    ARTICLE XIII. ALL OPERATIONS TO BE CONDUCTED IN A LAWFUL, PRUDENT MANNER

     Lessee shall conduct all operations under this lease in a lawful, prudent,
and good workmanlike manner for the effective and safe production of the mineral
substances covered by this lease, and to avoid unnecessary damage and injury to
the leasehold estate, and also to avoid damage and wastage of other natural
resources not covered by this lease. All operations of Lessee, whether conducted
directly by Lessee or by operators or contractors, shall be at the sole cost and
expense of Lessee.

     It is expressly covenanted and agreed that Lessor does not grant Lessee or
any person dealing with Lessee any right to subject the property hereinabove
described, nor any leased substances, to any lien-rights for labor or mechanic's
liens, nor to any materialmen's liens, nor to any other lien for any act,
omission, neglect, or performance of Lessee or its agents, employees, and
contractors. In the event any one shall file any notice or claim of lien against
said property or any estate in said property, Lessee shall take all necessary
steps expeditiously to have such notice or claim released of record. Lessee
shall save Lessor harmless from any and all lien notices and claims against said
land arising from any act or neglect of Lessee and any contractor or operator of
Lessee in any operations on or relating to the hereinabove described lands.

     Lessee shall not fence off or otherwise make inaccessible to livestock
lawfully on the surface of said premises any watering place without the written
consent of Lessor; provided, that Lessee shall not permit any livestock to come
upon any portion of the leasehold to pollute any surface or subsurface water
available or capable of being made available for domestic use or irrigation. In
the operations of Lessee, Lessee shall comply with all laws and regulations for
control of water which might be encountered or which might seep into any
formation, to avoid pollution of surface and underground waters as required by
Chapter 14, Title 73, Utah Code Annotated, 1953, as amended. Lessee shall comply
with all valid laws and regulations relating to prevention and suppression of
fires, make all necessary provisions for sanitary disposal of wastes, and in all
operations connected with said leasehold take appropriate measures for
protection of human life and prevention of injuries and disease.

     ARTICLE XIV. RIGHTS OF LESSOR FOR INSPECTIONS OF LEASEHOLD AND RECORDS

     Lessor, its officers, and agents have the right at all reasonable times to
enter upon the leased lands and premises to inspect the conditions of the
leasehold, the work done under the terms of this lease, and the production
obtained from the leasehold, such entry and inspections to be done in such a
manner as shall not unreasonably interfere with the lawful operations by the
Lessee in performance of the terms and conditions of this lease.

     Lessor also shall have the right to examine all books and records
pertaining to operations under this lease whether such books and records are
located within a building on the leased premises or located in an office
elsewhere and to make copies and abstracts of such records if desired by Lessor.
Lessor, its officers, and agents shall have the right to post upon or within the
leasehold such notices deemed proper or expedient by Lessor.

<PAGE>

                                                              
                                       -9-

     If Lessee maintains an office in another State or in a foreign country,
Lessee nevertheless shall maintain within the State of Utah proper and adequate
records relating to operations on this leasehold and also relating to production
of leased substances and payment of rentals and royalties. Lessee also shall
have a resident agent in the State of Utah to whom any and all notices may be
sent by Lessor and on whom process may be served. In the event of any change in
the address of Lessee's office in the State of Utah, Lessee shall promptly
furnish Lessor with written notice of such change of address within the State of
Utah. Examinations of records of Lessee by the Lessor shall be conducted at
reasonable times.

     In the event Lessee conducts core-drilling operations within the leasehold,
or by directional drilling from adjacent land, Lessor shall have a right of
inspection of core samples and any analysis made thereof and any assay;
provided, that any report obtained by Lessor of any core-drilling operations may
be declared confidential information by Lessee, in which event Lessor shall keep
such information in a separate confidential information file. Such information
shall not be disclosed to any competitor nor to any one except to a
representative of the Attorney General of the State of Utah until Lessee waives
confidentiality or upon surrender, expiration, or termination of this lease.

     After completion of any core drilling, Lessee shall notify Lessor; and
Lessee shall cause all core holes to be plugged or sealed as expeditiously as
possible after the need for keeping such core holes unplugged ceases, in
accordance with regulations and requirements of the Division of Oil, Gas, and
Mining.

        ARTICLE XV. OPERATIONS IN CONJUNCTION WITH MINING ON OTHER LANDS

     In the event Lessee, in the interest of economy in mining operations,
desires to conduct mining operations on or within the above-described lands in
conjunction with mining operations on or within any adjacent Federal, State, or
privately-owned land by utilization of shafts, inclines, or tunnels within
either the above-described lands or within adjacent lands, Lessee shall make
application in writing to the Board of State Lands & Forestry and submit with
such application a detailed plan of operations illustrating how leased
substances mined from the above-described lands can and will be mined,
segregated, and separately accounted for from leased substances mined from some
adjacent land. No such operations shall be conducted without written approval of
the Board. Any approval granted by the Board shall be conditioned upon proper
segregation and proper accounting and record keeping of leased substances mined
from each property. Separate records shall be required for accounting for leased
substances mined from the above-described lands.

     In the event Lessee desires to process or mill leased substances from the
abovedescribed land in conjunction with processing or milling of leased
substances from adjacent or some other lands, whether such processing or milling
is intended to be performed on the above-described land or on some other land,
Lessee shall submit to the Board a written application detailing how the leased
substances mined from the above-described lands shall be segregated and
separately accounted for in computation of royalty payments from leased
substances mined from other lands. Any Board approval for any such arrangements
shall be conditioned upon segregation of leased substances produced from the
above-described lands from mineral substances produced from other lands with
adequate safeguards to assure proper accounting for determination of royalty.

<PAGE>

                                                              
                                      -10-

     If application is granted for either type of operation or for both, all
procedures for either production or milling of minerals shall be subjected to
examination by the Division of State Lands & Forestry and by the Division of
Oil, Gas, and Mining to determine whether either type of arrangement functions
satisfactorily without detriment to the State of Utah. If such inspection
results in an adverse report with recommendations for modification or
discontinuance of such operations, a copy of the report with recommendations
shall be submitted as expeditiously as possible to the Lessee. If any
objectionable condition is not promptly remedied to safeguard the rights of the
State as Lessor, the Board of State Lands & Forestry shall have the right to
order discontinuance of such arrangement; and failure to comply with such order
of the Board shall constitute a breach of this Lease Agreement.

           ARTICLE XVI. SPECIAL REQUIREMENTS IN EVENT OF STRIP-MINING

     In the event Lessee desires to conduct any strip-mining or open-pit mining
or operations which will materially disturb the surface of the above-described
lands or some portion thereof, at least sixty (60) days before commencing such
type of mining activities, Lessee shall submit to the Division of State Lands &
Forestry the proposed plan of operations together with a proposed plan of
surface rehabilitation in compliance with the Utah Mined Land Reclamation Act
and in compliance with the Rules and Regulations adopted thereunder.  A copy of
such proposed plan of operations and proposed plan of surface rehabilitation
also shall be submitted to the Division of Oil, Gas, and Mining. No such
operations shall be commenced until the Division of Oil, Gas, and Mining
approves the plan of operations and approves a program of rehabilitation.
Security may be required of Lessee to assure appropriate rehabilitation in
accordance with the said statute and rules and regulations adopted thereunder.

          ARTICLE XVII. EQUIPMENT OR FACILITIES TO REMAIN WITH THE LAND

     Upon surrender, forfeiture, expiration, or termination of this lease, 
any and all underground timbering supports, shaft linings, rails, and other 
installations necessary for the support of underground tunnels, shafts, 
inclines, or other underground mine supports, together with all rails or head 
frames and all other underground construction and safety equipment annexed to 
the ground (excluding detachable motor-driven machinery) which cannot be 
removed without creating a danger to any shaft, tunnel, incline, or other 
underground improvements annexed to the mine, and including equipment 
installed underground to provide for ventilation of the mine or some portion 
thereof, shall be left within said land above described by the Lessee, 
operator, and contractor of Lessee and shall remain a part of the realty. 
Lessor shall acquire all rights thereto without indemnification of Lessee or 
operator or contractor for Lessee. Except as herein specifically excepted,

tools, and stockpiles of leased substances for which royalty has been paid 
shall remain the property of Lessee or operator or contractor for Lessee and 
Lessee or operator or contractor for Lessee may remove the same at the sole 
expense of Lessee or operator or contractor within two (2) months following

                                      -11-

of State Lands & Forestry for good cause shown shall have the right to grant a
reasonable extension of time beyond the period of two (2) months for removal of
any and all equipment which may be removed by Lessee or operator or contractor
as herein provided. At the end of such period, Lessor may consider abandoned and
lay claim to any or all equipment or stockpiles remaining on the premises.

     Upon expiration, surrender, forfeiture, or termination of this lease or
abandonment of the leasehold by Lessee, the Lessee shall cause to be sealed or

reasonable requirements of the Director of the Division of Oil, Gas, and Mining.

             ARTICLE XVIII. CONSENT TO SUIT IN STATE DISTRICT COURT

     It is agreed that if there arises any controversy between lessor and Lessee
or any successor in interest of Lessee which needs to be litigated, Lessee or
any one claiming by or under the Lessee shall bring such action in the District
Court of Salt Lake County, State of Utah, after compliance with the requirements
of State statutes for bringing suit, including compliance with the requirements
of the State Governmental Immunity Act, Title 63, Chapter 30, Utah Code

District Court for the District of Utah, nor in any other United States District
Court in some other state, nor in the District of Columbia.

             ARTICLE XIX. REMEDIES FOR DEFAULT BY LESSEE OR ASSIGNS

     This Mineral Lease and the terms and conditions of this lease agreement
issued by the State of Utah are made with the Lessee herein on condition that
Lessee and any lawful successor in interest to Lessee shall perform all

such default or breach given to Lessee or successor in interest addressed to
Lessee or successor in interest at the last address furnished by Lessee or
successor in interest by United States mail, then at the expiration of said
period of thirty (30) days immediately following such notice if the default or
breach has not been remedied, then at the expiration of said period of thirty
(30) days, at the option of the Lessor, Lessor may issue written notice of

                                      -12-

     In the event that the leasehold estate shall have been damaged or injured
by the acts or neglect of the Lessee or operator, contractor, or assigns of
Lessee, Lessor also shall have a right of action for damages and for restitution

materials, Lessee agrees to pay Lessor a Production Royalty on the materials
consistent with the prevailing State of Utah royalty for materials or minerals
of like kind.

The SELLER and BUYER agree that the following terms and conditions govern the
sale of the Product:

1.   TAXES:  All Federal, State or local taxes (except income taxes) now or
hereafter imposed in respect to this order, or any transaction involved herein
and/or the Production sale, use consumption, delivery, transportation of the
Product shall be for account of the BUYER, and if paid or required to be paid by
the SELLER, the amount thereof shall be added to and become a part of the price
payable to the BUYER hereunder.

2.   FINANCIAL RESPONSIBILITY:  If, in the reasonable opinion of SELLER, the
credit or financial responsibility of BUYER is, or becomes, impaired or
unsatisfactory, SELLER reserves the right to demand cash or satisfactory
security before making shipment.  If BUYER fails to provide cash or satisfactory
security to fully satisfy SELLER's demands, such failure shall constitute a
breach of the Agreement, and SELLER shall have the right to withhold further
shipments and/or to cancel this Agreement or any part of this Agreement at the
option of SELLER, without any liability or obligations on the SELLER.  Such
withholding of shipments and/or cancellation, however, shall not affect the
BUYER's liability for damages, including the costs associated with reshipment of
tank railcars or tank trucks due to BUYER's failure to meet its financial
responsibilities.  Additionally, SELLER reserves the right to possession of the
Product and the right to stop Product in transit.  The acceptance by SELLER of
any payment less than the full amount due shall not be a waiver of any rights of
SELLER.

3.   PAYMENT:  Payment of the price shall be made in lawful money of the United
States, as per the Payment Terms specified on the front of this document.  If
payment is not made when due, or in the manner herein provided, SELLER may at
its option, without notice, cancel this Agreement as to all or any part of the
unfilled quantity.  Sales and use taxes paid or required to be paid by the
SELLER, which are part of the price pursuant to Paragraph 1, shall be included
in the billing for the Product delivery.  All other taxes which become part of
the price pursuant to Paragraph 1, the amount of which cannot be determined on
the invoice date, will be billed when they become known and will be payable
within thirty (30) days of billing date.

4.   TITLE:  Unless otherwise specified, title to and risk of loss of any
shipment of Product shall pass from SELLER to BUYER FOB railroad tank car or
tank truck at the destination point unless BUYER supplies the equipment to
transport the Product, in which case title and risk of loss shall pass FOB
railroad tank car or tank truck at loading point.

5.   LIABILITY: SELLER assumes no responsibility for the condition of trucks,
tank cars and related equipment supplied by BUYER.  SELLER is not responsible
for, and BUYER agrees to indemnify, defend, and save harmless the SELLER against
any, and all liabilities, claims, investigations, suits, causes of action,
judgments, losses, penalties, costs or expenses (including, without limitation,
reasonable attorneys fees) (collectively, "Liabilities"), arising out of or in
consequence of, or alleged to have arisen out of or in consequence of, in whole
or in part 1) any breach or default by the BUYER of the terms or conditions of
this Agreement, 2) any and all negligent acts by the BUYER, 3) any and all civil
or criminal breaches or violations or statutes, regulations, ordinances, or
otherwise by the BUYER, 4) any and all Liabilities predicated on theories of
strict liability, whether imposed or arising under a statute, ordinance,
regulation, or at common law or otherwise by the BUYER, 5) any and all improper
acts of loading, transporting, storage, handling, or application of the Product
by the BUYER, or, 5) any subsequent resale of the Product or other disposal by
the BUYER, including, but not limited to, any and all representations or
warranties that the BUYER makes to a third party in the course of the resale or
other disposal of the Product, or 7) any and all other acts or omissions of
BUYER, whether arising under this contract or otherwise, which result in
Liabilities to the SELLER.  BUYER hereby assumes liability for, and shall
reimburse SELLER for, all damage to, and all loss or description of, any private
tank car or tank truck (including the fittings and appurtenances thereto)
occurring while said tank car or tank truck is in the possession of BUYER,
except when such damage, loss or destruction does not result from the negligence
or default of BUYER.  BUYER's reimbursement of SELLER hereunder shall be limited
to the lessor of: (a) the actual cost to SELLER of repairing, reconditioning or
replacing said tank car or tank truck, or (b) the actual depreciated cash value
of said tank car or tank truck at the time of such damage, loss or destruction.
BUYER shall report promptly to SELLER all damage to, or loss or destruction of,
any such tank car or tank truck, howsoever arising, occurring while such tank
car or tank truck is in the possession or under the control of BUYER.

6.   WARRANTY:  Attached to this Agreement is a Composite Analysis, for the
dates indicated, of the Product.  SELLER OR PRODUCER MAKE NO EXPRESS OR IMPLIED
WARRANTIES OF ANY KIND, INCLUDING WHETHER THE PRODUCT CONFORMS TO THE ATTACHED
COMPOSITE ANALYSIS.  NO WARRANTY BY SELLER OR PRODUCER (OTHER THAN WARRANTY OF
TITLE AS PROVIDED IN THE UNIFORM COMMERCIAL CODE) SHALL BE IMPLIED OR OTHERWISE
CREATED UNDER THE UNIFORM COMMERCIAL CODE INCLUDING, BUT NOT LIMITED TO,
WARRANTY OF MERCHANTABILITY OR WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE.

7.   NOTICE:  The BUYER shall give written notice of any claim for any cause
whatsoever within ten (10) days after arrival of any shipment at destination,
and failure to do so shall constitute a waiver by the BUYER of all claims with
respect to such shipment.  For any defect of quality established, SELLER's
liability shall be limited to replacing any defective acid delivered hereunder
and in no event shall SELLER incur liability for defects or damage to Products
in which acid delivered hereunder is used or for any other kind of
consequential, nominal, or incidental damages.

8.   INVOICE: SELLER shall invoice BUYER for each delivery on the basis of price
provided herein, and each such delivery shall constitute a separate and
independent sale.  SELLER's weights and analyses shall govern unless proven to
be in error.

9.   MUTUALLY AGREED PRODUCER: BUYER agrees that SELLER may meet its commitments
under this Agreement by having a mutually agreed producer deliver Product on
behalf of SELLER, so long as the agreed producer otherwise agrees to meet the
terms and conditions of this Agreement.

10.  FORCE MAJEURE: This Agreement is subject to the following conditions of
force majeure.  Any strike, lockout, difference with workmen, accident, fire,
explosion, flood, earthquake, storm, unavoidable accident, mechanical breakdown
(including shutdowns for maintenance and inventorying) mobilization, war
(whether declared or undeclared), riot, rebellion, revolution, requirement,
regulation, restriction, or other act of any government, whether legal or
otherwise, the elements, inability to secure or delay in securing fuel, or other
supplies or materials, or power, necessary for the operation of the mines and
plants where the Product sold hereunder is produced or consumed, economic
shutdown of SELLER's or BUYER's mine or plant facilities, delays or interruption
to, or destruction of mines or plants of SELLER or BUYER, or any other acts
beyond the control of the parties, whether or not of the nature or character
hereinabove specifically enumerated which delays or interferes with the
performance of this Agreement shall be considered sufficient justification for
delay in making shipments, delivery or performance hereunder, in whole or in
part, until such cause ceases to exist; and this Agreement shall be deemed
suspended as long as such cause prevents or delays its execution.  Neither party
shall be responsible for or liable to the other for damages or expenses incurred
or sustained because of any delay or failure to perform because of a condition
of force majeure.  If under any of the conditions set forth in this Paragraph,
supplies of sulfuric acid available to SELLER are insufficient to complete
delivery of orders accepted by SELLER prior to the occurrence of the condition
or to SELLER's nominated long term regular contract customers.  SELLER shall
allocate available supplies pro rata to such long term customers until such
customers' contractual requirements are met by SELLER, and then SELLER may, at
its option, allocate available supplies (having first satisfied the long term
customers' contractual requirements) in a manner it deems suitable, without
liability for any damages sustained by BUYER.  A nominated long term regular
contract customer is a minimum annual tonnage commitment of 50,000 sl or more
and five (5) years or longer in original contract duration.  BUYER shall
allocate purchased supplies pro rata to such long term suppliers until such
suppliers' contractual requirements are met by BUYER, and then BUYER may at its
option allocate purchases (having first satisfied the long term suppliers
contractual requirements) in a manner it deems suitable without liability for
damages sustained by supplier.  If deliveries are interrupted or delayed for any
condition of force majeure, the amount of Product which is not delivered at the
regular order rate during the period of any such suspension or reduction shall,
at the option of SELLER, be deducted from the full amount which otherwise would
have been delivered under this order in which event SELLER shall not be
obligated to make up such omitted deliveries either during the order period or
after termination thereof.  It is understood and agreed that SELLER shall be
under no obligation to operate its copper smelters nor will it be under any
obligation to operate its sulfuric acid plants except as, and to the extent
that, it shall have available for that purpose sulfurous cases of commercial
grade, produced in the course of operating its smelter and lack of such gases
shall be deemed a cause beyond SELLER's control and subject to the Force Majeure
provision and, notwithstanding paragraph 9 of this Agreement, SELLER is not
obligated to find another producer to meet its obligations under a condition of
force majeure.

11.  HAZARDS: BUYER acknowledges that there are hazards associated with the use
of the Product.  BUYER agrees to make its personnel concerned with the Product
aware of the hazards and assumes all responsibility for the warning of its
employees and independent contractors of all hazards to persons and property in
any way connected with Product.  BUYER also assumes all responsibility for the
risks of using Product in combination with other articles or substances and in
any manufacturing process.  The SELLER shall not be liable to the BUYER for any
consequential, nominal, or incidental damages, including lost profits, arising
out of the use, handling, storage, or any application or activity related to the
Product.  The SELLER shall not be liable to the BUYER for compensation,
reimbursement or damages on account of loss of prospective profits or
anticipated sales or on account of expenditures, investments or commitments in
connection with the business or good will of the BUYER caused by failure of
Product to conform to the specifications herein set forth.

12.  CLAIMS: The BUYER will promptly notify the SELLER in writing of any
claims, demands, suit, action, or proceeding with respect to the Product.

13.  GOVERNING LAW: This Agreement shall be deemed to be made under and shall be
governed by the laws of the Sale of Utah in all respects, including matters of
construction, validity, and performance.

14.  ENTIRE AGREEMENT: This Agreement constitutes the entire Agreement between
the parties as to the subject matter hereof and may not be changed or modified
except by signed writing by the SELLER and BUYER.

15.  AFFILIATES: This Agreement inures to the benefit of affiliates,
subsidiaries, or parents of the parties.

16.  SURVIVAL: The provisions of paragraphs 2, 3, 5 and 11 above survive
termination of this Agreement.

17.  PRICE PROTECTION: If, after the interval designated in the contract, BUYER
is offered material of equal quality by a responsible domestic manufacturer for
delivery to the same destination on like terms and conditions as herein provided
in quantities adequate to fulfill the entire commitment to deliver product
during the entire remaining term (time left) of this contract at a lower
delivered cost to BUYER than the delivered cost hereunder.  SELLER, within
thirty days of receipt of written evidence of same, shall either meet such lower
delivered cost or release BUYER from their obligation to purchase by cancelling
this contract.  The written evidence shall be in the form of a signed proposal
to sell sulfuric acid to BUYER on the corporate stationery of the manufacturer
or distributor.  It must contain the price for sulfuric acid delivered to
BUYER's facilities, the provision for changing the price, the volume offered,
the term (dates the supply is to commence and end), and the product
specifications.

                              PURCHASE OPTION AGREEMENT

         THIS PURCHASE OPTION AGREEMENT made effective as of the 1st day
of May, 1995 (the "Effective Date"), by and between those persons whose names
and addresses are shown on EXHIBIT A attached hereto and incorporated herein
(individually an "Owner" and collectively the "Owners") and SUMMO USA
CORPORATION, a Colorado corporation, whose address is 1776 Lincoln Street,
Denver, Colorado 80203, ("Summo").

                                       PREAMBLE

         1.   Owners are the owners of two parcels of real property. One of the
parcels contains approximately 320 acres; the other contains approximately 80
acres. The 320 acre parcel is hereafter referred to as the "Plant Parcel" and
the 80 acre parcel is hereafter referred to as the "Exploration Parcel." Both
parcels are hereafter collectively called the "Properties." They are located in
San Juan County, Utah, and are more particularly described on EXHIBIT B attached
hereto and incorporated herein.

         2.   Subject to the Petrotech oil and gas lease hereafter discussed in
Section 4(e) (the "Petrotech Matter"), Summo desires to carry out certain
mineral exploration work on the Properties and certain survey and site
evaluation work on the Plant Parcel. Summo also wishes to acquire the option to
purchase the Properties.


         3.   Owners desire to make the Properties available for the conduct by
Summo of such exploration and survey-site evaluation work thereon and to grant
Summo the option to purchase the Properties.


         NOW THEREFORE, in consideration of Twenty Thousand Dollars
($20,000.00) in hand paid to Owners (the "Signing Bonus"), the receipt and
sufficiency of which is hereby acknowledged, and further in consideration of the
mutual covenants, agreements, and promises herein contained, the parties agree
as follows:

    expressly excluded, all water and water rights incident thereto and all
    improvements and personal property thereon, free and clear of all liens and
    encumbrances, for a total purchase price of Two Hundred Forty Thousand
    Dollars ($240,000.00) (the "Purchase Price). Summo shall be entitled to a
    credit against the purchase price for all costs and expenses incurred by

    are placed into commercial production at any time during the term of the
    Option (the "Term") as hereafter defined, Summo shall exercise the option
    by providing written notice of exercise to Owners within ten (10) days of
    the date of first shipment for sale of ores, concentrates, metals and other
    mineral products. Within thirty (30) days after such notice Summo shall pay
    the Purchase Price to Owners in the manner provided in Section 6(c) 
    hereof. "Commercial production" shall mean the processing and sale of ores,
    concentrates, metals and other mineral products which have been mined on
    either of the Properties but which shall not include processing for the
    purpose of testing or milling by a pilot plant. Whether or not either of
    the Properties are placed into commercial production during the Term of the
    Option, Summo shall also have the right to exercise the Option as hereafter
    provided.

         (b) The Option shall NOT include any rights in and to any oil, gas
    distillate, other hydrocarbons or sulfur appurtenant to the Properties (the

         (a) Subject to the Petrotech Matter, Summo shall have the exclusive
    possession of and surface rights priority in and to the Properties during
    the Term of the Option and thereafter if the Option is exercised.

         (b) In the event during the Term of the Option that the Owners shall

<PAGE>

    portion of the Properties, the surface rights to the Properties of any
    lessees or third parties thereunder shall at all times be subordinate to
    the surface rights to the Properties herein granted to Summo (the "Surface
    Rights Priority"), which shall be specifically designated in the Short Form
    of Agreement to be executed by Owners and Summo pursuant to Section 23
    hereof.



4.       TITLE.

         (a) Lisbon Land & Livestock Company ("Lisbon L&L"), a Colorado general
    partnership, is record owner of the Properties. The Owners warrant that
    Warren J. Wood, Wilbur L. Wood, Wesley 0. Wood, Wm. H. Wood and Willard G.
    Wood constitute all of the general partners of Lisbon L&L. Except for the
    Petrotech Matter, Owners warrant that they are in sole possession of the
    Properties, that they have the right to enter into this Agreement, that
    they know of no other person claiming any interest in the Properties or the
    ground covered thereby, and that the Properties are free from all liens,
    encumbrances leases, claims of leasehold interests, restrictions, easements
    and any other limitations on the rights granted Summo hereunder, except
    liens for property taxes not yet due and payable. Subject to the Petrotech
    Matter, Owners further warrant to Summo the quiet enjoyment of the
    Properties and the right to explore, develop and mine the same in accordance
    with the rights herein granted to Summo.

         (b) Owners warrant and will defend title of the Properties against all
    persons whomsoever except for the Petrotech Matter.

         (c) At Summo's request, Owners shall take all action necessary
    (including judicial proceedings) to remove any cloud from or cure any
    defect in their title to the Properties or the ground covered thereby,
    including the Petro-Tech Oil & Gas Lease as hereafter defined and obtaining
    the Petro-Tech Sign-Off as hereafter defined. If Owners fail or refuse to
    take any such action, Summo may take any such action in Owners' names and
    at Owners' expense. In the event Owners are unable to obtain the requisite
    Petro-Tech Sign-Off within the time frame required under Section 4(e)(iv),
    then any expenses or costs thereafter so incurred by Summo, including any

                                          4


<PAGE>

    cost incurred by Summo to obtain the Petro-Tech Sign-off, shall be credited
    against the Purchase Price. Owners agree to cooperate with Summo in any
    such action.

         (d)  Summo shall not be estopped to deny the validity of Owners'
    title.

         (e)  (i)  On or about January 4, 1993, Owners leased the Plant Parcel
    to Petrotech Corp. ("Petrotech") pursuant to a certain Oil and Gas Lease
    that was recorded in the Recorder's Office of San Juan County, Utah as
    Entry No. 005355 (the "Petrotech Oil-Gas Lease"), a true, correct and
    complete copy of which is attached hereto and made a part hereof as EXHIBIT
    E.

              (ii)  To the best of Owners' actual knowledge, Petrotech has not
    conducted any testing, prospecting or drilling activities on the Plant
    Parcel nor has Petrotech installed or constructed any pipelines, tanks,
    roads, buildings or other structures thereon.

              (iii)   Owners acknowledge that during the term of the Option,
    Summo intends to conduct exploratory investigations, mineral prospecting,
    soil testing, survey and geophysical surveys, core drilling and other
    studies on the Plant Parcel to determine, among other things, the
    feasibility of constructing a plant facillity thereon for use in
    conjunction with Summo's copper exploration and mining activities in the
    Lisbon Valley and that extensive acreage is required for such a facility.
    Owners further acknowledge that conflicts might arise between Summo and
    Petrotech regarding the use of the surface of the Plant Parcel during the
    Term of the Option and thereafter if the Option is exercised by Summo.


              (iv)  Owners accordingly agree to use their best efforts to
    obtain at their sole expense on or before July 31, 1995 a recordable
    document executed by Petrotech or its successors and assigns (the
    "Petro-Tech Sign-off") which either wholly terminates the Petrotech Oil-Gas
    Lease or which subordinates the rights of Petrotech or its successors and
    assigns to utilize the surface of the Plant Parcel to the rights of Summo
    as herein granted as well as the rights of Summo as owner of the Plant
    Parcel if the Option is exercised. The terms of such subordination must be
    satisfactory to Summo as evidenced by a written approval executed by Summo.
    If the  Petro-Tech Sign-off approved by Summo is received by Escrow Agent
    by August 7,


                                          5


<PAGE>

    1995, promptly upon receipt thereof Escrow Agent shall distribute the
    $20,000 Signing Bonus Balance to Owners. If the Petro-Tech Sign-off is not
    received by Escrow Agent by August 7, 1995, (i) Escrow Agent shall return
    the $20,000 Signing Bonus Balance to Summo and (ii) this Agreement/Option
    shall continue in full force and effect in accordance with its terms and
    conditions unless terminated by Summo as hereafter provided.

5.       UNDIVIDED INTEREST. If the interest claimed by any Owner in any
    portion of the Properties is less than one hundred percent, the interest
    claimed by such Owner is set forth in EXHIBIT A. Any representation or
    warranty of title made by any Owner shall apply only to the interest set
    forth in EXHIBIT A.

6.       OPTION EXERCISE, TERM OF OPTION AND PAYMENT OF PURCHASE PRICE.

         (a)  OPTION EXERCISE. Subject to the provisions of Section 1(a), the
    Option may be exercised by Summo at any time during the term of the Option
    by providing written notice of Option exercise to Owners.

         (b)  TERM OF OPTION. The Term of the Option shall be for the period
    commencing with the Effective Date hereof and ending September 30, 1995.

         (c)  PAYMENT OF PURCHASE PRICE. Within thirty (30) days after notice
    of Option exercise is given, Summo shall pay the Purchase Price by check
    which shall be made payable to and shall be transmitted to the Escrow
    Agent. The amount of Purchase Price shall be reduced by the amount of any
    credit to which Summo is entitled under Section 1(a) and 4(c) hereof. The
    Escrow Instructions will instruct the Escrow Agent how the payment shall
    be disbursed. Upon making such payment to the Escrow Agent, Summo shall be
    deemed to have paid the Purchase Price to Owners, their heirs,
    representatives, successors, and assigns, and thereupon Summo shall be
    discharged to the extent thereof as if the payment had been made directly
    to Owners, or to any person, firm or corporation entitled thereto, and
    Summo shall not be liable for the ultimate distribution or receipt of any
    payment or payments.

          (c)  No assignment by Summo of the whole or an undivided interest in
     this Agreement or the Option shall relieve Summo of liability for any
     subsequent breach by the assignee of any of Summo's obligations hereunder.
     If this Agreement/Option is assigned as to a segregated portion of the
     Properties, default by the holder hereunder of that portion shall not
     affect the rights of holders hereunder of any other portion.

          (d)  If Owners or any of them receive and propose to accept a bona 
     fide written offer from an unrelated third party to purchase, subject to 
     the terms of this Agreement, and purpose to accept all or any part of 
     Owners' interest in the Properties or in this Agreement, such Owners 
     shall first offer the interest to Summo stating the interest proposed to 
     be sold or otherwise disposed of, the offering price from such third 
     party and the other terms and conditions of sale. Summo may accept the 
     offer on the same terms and conditions as such third party offer by 
     notice to Owners given within 60 days following the date of Owners' 
     offer. If Summo does not accept Owners' offer, Owners may sell or 
     otherwise dispose of the interest offered to Summo at a price and upon 
     terms and conditions equal to or less favorable to the third party than 
     those offered to Summo provided that the sale or other disposition is 
     effectuated within 120 days from the effective date of Owners' offer. 
     Any sale or other disposition shall be subject to the terms of this 
     Agreement, including this subsection (d), all of which shall survive the 
     closing of any such sale in full force and effect. If Owners do not sell 
     or otherwise dispose of the interest offered within such 120 day period, 
     the provisions of this subsection (d) shall apply to any subsequent 
     offer received by Owners.

21.      NO TRANSFER OR ENCUMBRANCE.  Without Summo's prior written
     consent, neither Owners nor any Owner during Term of this 
     Agreement/Option shall (a) sell, transfer, assign or convey any interest 
     in the Properties without Summo's prior written consent or otherwise in 
     accordance with the provisions of Section 20(d) hereof; (b) do or fail 
     to do any act or thing which would cause or permit any part of the 
     Properties to be pledged, collateralized or stand as security for any 
     matter whatsoever; (c) enter into any leases or other agreements 
     concerning the Properties or any part thereof except in connection with

     Purchase Price), the failure of performance shall be excused and the period
     for performance and the Term of the Option and this Agreement shall be
     extended for an additional period equal to the duration of the Force
     Majeure. Upon the occurrence and upon the termination of any Force Majeure,
     Summo shall promptly notify Owners. Summo shall use reasonable diligence to
     remedy a Force Majeure but shall not be required against its better
     judgment to settle any labor dispute or contest the validity of any law or
     regulation or any action or inaction of civil or military authority.

          (b)  "Force Majeure" means any cause beyond Summo's reasonable
     control, including law or regulation, action or inaction of civil or
     military authority, inability to obtain any license, permit, or other
     authorization that may be required to conduct operations on or in
     connection with the Properties in connection with this Agreement; unusually
     severe weather, mining casualty, fire, explosion, flood, insurrection,
     riot, labor dispute, inability after diligent effort to obtain workmen or

                            SHORT FORM OF OPTION AGREEMENT

    This short Form of Option Agreement is between those persons whose names 
and addresses are shown on EXHIBIT A attached hereto and made a part hereof 
(individually an "Owner" and collectively the "Owners") and Summo USA 
Corporation, a Colorado corporation, whose address is 1776 Lincoln Street, 
Denver, Colorado 80203 (hereinafter referred to as "Summo").

                                       RECITALS

    Effective _________________, 1995 (the "Effective Date"), the Owners and 
Summo entered into a Purchase Option Agreement ("Option Agreement") by which 
Summo has been granted an exclusive option (the "Option") to purchase certain 
real properties located in San Juan County, Utah (the "Properties") more 
particularly described on EXHIBIT B attached hereto and made a part hereof. 
The Option does not include any rights in and to any oil, gas distillate, 
other hydrocarbons or sulphur appurtenant to the Properties (the "Oil and Gas 
Rights"), which shall remain the property of Owners. The parties hereby 
execute this Short Form of Option Agreement (the "Short Form") to summarize 
for recording purposes certain features of the Option as follows:

         1.   TERM AND PAYMENT. The term of the Option is from the Effective
Date through September 30, 1995 within which Summo has the right to exercise
the Option and then to pay the purchase price for the Properties within thirty
days after such exercise of the Option.

         2.   OPERATIONS. During the term of the Option, Summo has the right to
conduct exploratory investigations, mineral prospecting, soil testing, survey
and geological


<PAGE>

surveys, core drilling, shaft sinking, tunnel and mine buildings, the removal of
ore for testing purposes, the right to erect and maintain on the Properties any
improvements, structures or facilities including mines and buildings, for
example, that may be necessary or convenient to Summo.

         3. EXCLUSIVE POSSESSION. Subject to the rights granted under a certain
Oil & Gas Lease dated on or about January 4, 1993 that was recorded in the
Recorder's Office of San Juan County, Utah as Entry No. 005355, Summo shall
have exclusive possession of and surface rights priority in and to the
Properties during the term of the Option.

         4. CONFIDENTIALITY. During the term of the Option all information
obtained by Owners or their representatives from Summo or rising out of Summo's
activities on the Properties shall be kept strictly confidential by Owners.

         5. TERMINATION. Summo has the right at any time to terminate the
Option.

         6. RIGHT OF FIRST REFUSAL. If Owners receive a bona fide written offer
from an unrelated third party to purchase all or any part of Owners' interest in
the Properties or in the Option, Owners shall first offer the interest to Summo
on the same terms and conditions. Summo has 60 days to accept such offer. If
Summo does not accept such offer, the Owners may dispose of the interest
offered to Summo at a price and upon such terms and conditions equal to or less
favorable to the third party than those offered to Summo provided that the sale
or other disposition must be effected within 120 days from the date of the
offer to Summo. Any sale or other disposition shall be subject to the terms of
the Option, including the right of first refusal, all of which shall survive the
closing of any such sale in full force and effect. If Owners do not sell or
otherwise dispose of the interest


                                          2


<PAGE>

offered to Summo within such 120-day period, the right of first refusal
continues to apply  to any subsequent third party offer or offers received by
Owners.

         7. NO TRANSFER OR ENCUMBRANCE. Without Summo's prior written consent,
neither the Owners nor any Owner during the term of the Option shall:

              (a) sell, transfer, assign or convey any interest in the
Properties without Summo's prior written consent or otherwise in accordance
with the right of first refusal provisions contained in the Option;

              (b) do or fail to do any act or thing which would cause or permit
any part of the Properties to be pledged, collateralized or stand as security
for any matter whatsoever; or

              (c) enter into any leases or other agreements concerning the
Properties or any part thereof except in connection with the Oil & Gas Rights.
In the event, however, that any leases or other agreements are entered into
with respect to the Oil & Gas Interests in the Properties, the surface rights
to the Properties or any part thereof granted in connection with any such
leases or agreements shall be subordinate in all respects to the Surface Rights
Priority granted to Summo under the Option.

              8. SUMMO RIGHTS UPON TERMINATION OR EXPIRATION OF OPTION.
Notwithstanding the expiration of the Option or Summo's failure to exercise the
Option, Summo shall have the right of access to and across the Properties
following the expiration or termination of the Option as follows:

                   (1) for a period of six months thereafter to enable Summo to
remove from the Properties all buildings, structures, machinery, equipment,
personal


                                          3


<PAGE>

property, fixtures and improvements owned by Summo or erected or placed on or 
in the Properties by Summo except mine timbers in place;

              (2) for as long as is necessary after termination or failure to
exercise  the Option Summo shall have the right of access to and across the
Properties for reclamation purposes.

         9. COUNTERPARTS. This Short Form may be executed in any number of
counterparts, each of which shall be deemed to be an original and all of which
together shall constitute one and the same agreement.

         10. ADDITIONAL TERMS. Additional terms and conditions of the Option
are contained in the Option Agreement between the parties. This Short Form of
Option Agreement shall not limit, decrease, increase or in any manner affect
any of the terms and conditions of the Option or any rights, interests or
obligations of the parties thereunder. This Short Form is being recorded for
the purpose, INTER ALIA of serving notice of the interests held by Summo in the
Properties.

    IN WITNESS WHEREOF, the parties have executed this Short Form of Option
Agreement as of the       day of                1995.

    be payable within thirty (30) days after St. Mary gives notice that it
    elects to exercise the Option.

2.       OPTION EXERCISE.  St. Mary's option to purchase the Property shall be
    exercisable by delivery to Owners of notice of its option exercise.  Within
    thirty (30) days of such notice, Owners shall deliver one or more general
    warranty deeds conveying the Property to St. Mary, and St. Mary shall pay
    to Owners the unpaid balance of the purchase price.  The deeds shall be in
    the form of Exhibit C attached hereto.  Owners agree to execute such other
    documents and perform such other acts as St. Mary may reasonably require to
    affect the transfer of complete title of the Property to St. Mary.  All
    recording fees shall be paid by St. Mary.

3.       SPECIFIC PERFORMANCE.  In addition to the standard remedies
    available by law to any party in the event of a breach of this agreement,
    Owners and St. Mary hereby agree that St. Mary shall be entitled to the
    remedy of specific performance with respect to its option exercise rights.
    The availability of the remedy of specific performance is expressly
    provided in lieu of escrow provisions, originally proposed by St. Mary but
    deleted at the request of Owners, pursuant to which Owners would have
    executed and delivered general warranty deeds to an escrow agent at the
    time this agreement was made.


4.       EXCLUSIVE POSSESSION.  St. Mary shall have the exclusive possession of
    the Property during the term of this Agreement.

5.       TITLE.

         (a)  Owners warrant that they are in possession of the Property, that
    they have the right to enter into this Agreement, that they know of no
    other person claiming any interest in the Property or the ground covered
    thereby, and that the Property is free from all liens and encumbrances,
    except liens for property taxes not yet due and payable.


                                          2

    Owners further warrant to St. Mary the quiet enjoyment of the Property and
    the right to explore, develop, and mine the same.

         (b)  Owners warrant and will defend title of the property against all
    persons whomsoever.

         (c)  At St. Mary's request, Owners shall take all action necessary
    (including judicial proceedings) to remove any cloud from or cure any title
    defect to the Property.  (Note: Owners shall have no obligation to St. Mary
    to cure surface disturbances resulting from prior mining activities.) If
    Owners fail or refuse to take any such action, St. Mary may take any such
    action in Owners' name.  Owners agree to cooperate with St. Mary in any
    such action taken.  If the United States or any third person attacks the
    validity of any of the patented mining claims included in the Property for
    any reason, St. Mary shall have no obligation to defend the validity of the
    claim.

         (d)  St. Mary shall not be estopped to deny the validity of Owners'
    title.

6.       UNDIVIDED INTEREST.  The interest in the Property claimed by each
    Owner is set forth in Exhibit A.  Any representation or warranty of title
    made by any Owner shall apply only to the interest set forth in Exhibit A.

7.       OPTION PAYMENTS.

         (a)  Concurrent with the execution of this Agreement by Owners, St.
    Mary has made an option payment to Owners in the amount of $ 10,000,
    receipt of which is hereby acknowledged by Owners.

         (b)  St. Mary shall pay to Owners further option payments on or before
    the dates and in the amounts as follows:

    to Owners in the percentage shares set forth in Exhibit A and mailed to the
    respective addresses shown in Exhibit A.

9.       OPERATIONS.

         (a)  SCOPE.  During the term of this Agreement, St. Mary shall have
    free and unrestricted access to the Property, and shall have the right and
    privilege of conducting exploratory investigations and prospecting for
    mineral deposits on the Property, effective during the life of the Option,
    and that prospecting shall include, but not be limited to, soil testing,
    geophysical surveys, core drilling, shaft sinking, tunnel and mine building
    and the removal of ore for testing purposes but not removal of ore for
    sale.  St. Mary shall have the right to erect and maintain upon the
    Property any improvements, structures or facilities including mines, shafts
    and tunnels as may be necessary or convenient for the conduct of its
    operations.

         (b)  STANDARDS OF OPERATION.  St. Mary shall conduct all operations on
    the Property in a good and workmanlike manner and in accordance with
    accepted mining practice.

         (c)  COMPLIANCE WITH LAW; RECLAMATION:  St. Mary shall endeavor in good
    faith to comply with applicable provisions of federal, state and local laws
    and regulations, as required by the operating permits issued to St. Mary by
    these agencies under which St. Mary shall conduct its operations.  If this
    Agreement is terminated, St. Mary shall reclaim only those portions of the
    Property disturbed by its operations, and in compliance with all applicable
    governmental laws, regulations and orders.  St. Mary shall have the right,
    without payment of any additional consideration to Owners, to enter upon
    the Property subsequent to termination of this Agreement for purposes of
    performing such reclamation work.  Owners shall be notified prior to St.
    Mary re-entering the Property for reclamation purposes.


                                          4

<PAGE>

10.      NO IMPLIED COVENANTS.  No covenants or conditions relating to the
    exploration or related operations on or in connection with the Property, or
    the timing thereof, other than those expressly provided in this Agreement,
    shall be implied.  After commencing any exploration or related operations
    on or in connection with the Property and so long as this Agreement has not
    been terminated before the expiration of its term, St. Mary may in its sole
    discretion curtail or cease such operations so long as it continues to make
    any payments due Owners under this Agreement subject to the provisions of
    Section 17 hereof.

11.      PROTECTION FROM LIENS AND DAMAGES.  St. Mary shall keep the Property
    free of liens for labor performed or materials or merchandise furnished for
    use on the Property under this Agreement, and shall hold Owners harmless
    from all costs, loss, or damage which may result from any work or
    operations of St. Mary or its occupancy of the Property.

12.      TAXES.  Owners shall pay all taxes levied against the Property prior
    to the date of this Agreement.  St. Mary shall pay or reimburse Owners for
    all taxes levied against the Property during the term of this Agreement.
    In the case of taxes for the calendar year in which this Agreement
    commences, and for the calendar year in which this Agreement ends, there
    shall be an apportionment between the parties, St. Mary to bear the
    proportion of taxes upon the Property applicable to the part of the
    calendar year included hereunder, and Owners to bear the balance of the
    taxes.  St. Mary shall pay all taxes levied during the term of this
    Agreement against all buildings, structures, machinery, equipment, personal
    property, fixtures, and improvements placed upon the Property by St. Mary,
    and all taxes levied against St. Mary as an employer of labor.  All taxes
    shall be paid when due and before delinquent, but St. Mary shall be under
    no obligation to pay any tax so long as the tax is being contested in good
    faith and by appropriate legal proceedings and the nonpayment thereof does
    not adversely affect any right, title, or interest of Owners in or to the
    Property.

13.      INSURANCE.  St. Mary shall carry at all times during the term of this
    Agreement worker's compensation and other insurance required by state laws
    and mining regulations.

14.      INSPECTION.

         (a)  Owners or their authorized representative may enter on the
    Property at any reasonable time for the purpose of inspection, but shall
    enter at Owners' own risk and so as not to hinder unreasonably the
    operations of St. Mary.  Owners shall indemnify and hold St. Mary harmless
    from any damage, claim, or demand by reason of injury to or the presence of
    Owners, their agents or representatives on the Property.

         (b)  Owners or their authorized representative may, at any reasonable
    time, inspect any records pertinent and necessary for substantiating the
    compliance of St. Mary with the provisions of this Agreement.

15.      DATA.

         (a)  Upon the execution of this Agreement, Owners shall deliver to St.
    Mary all drill core, all geological, geophysical, and engineering data and
    maps, logs of drill holes, results of assaying and sampling, and similar
    data concerning the Property (or copies thereof) which are in Owners'
    possession or control.

         (b)  Upon the surrender or other termination of this Agreement (except
    upon exercise of the Option and payment of the full purchase price as
    provided in Section 6 hereof), St. Mary shall, within sixty days after
    termination, (i) return to Owners all drill core and original data
    delivered by Owners to St. Mary which are then in St. Mary's possession or
    control, and (ii) make available for inspection by Owners all factual
    geological and geophysical data and maps (not including interpretive data),
    logs of drill holes, drill core or cuttings and results of assaying and
    sampling pertaining to the Property which St. Mary has obtained as a result
    of its exploration work under this Agreement and which are then in St.
    Mary's possession or control.  Upon Owners' request made within ninety (90)
    days after termination of this Agreement, St. Mary shall at Owners' expense
    provide Owners with the drill core or cuttings designated by Owners


                                          6

<PAGE>

    and with copies of any portion of the factual geological and geophysical
    data and maps (not including interpretive data), logs of drill holes, and
    results of assaying and sampling, designated by Owners.  St. Mary makes no
    representation or warranty as to the accuracy or completeness of any such
    data or information, and shall not be liable on account of any use by
    Owners or any other person of any such data or information.  St. Mary shall
    not be liable for the loss or destruction of any drill core or cuttings.


16.      CONFIDENTIALITY.  During the term of this Agreement all information
    obtained by Owners or their authorized representatives from St. Mary or
    arising out of St. Mary's activities on the Property pursuant to this
    Agreement shall be kept strictly confidential by Owners and shall not be
    released to any third party except with the prior written consent of St.
    Mary.

17.      TERM, TERMINATION AND SURRENDER.

         (a) The term of this Agreement shall be for a period of four (4) years
    from the date hereof unless sooner surrendered or otherwise terminated, or
    until the earlier exercise of the Option.

         (b) It is also agreed that a failure by St. Mary to make an option
    payment within 30 days of the due date therefor as provided in Section 7(b)
    hereof shall also constitute a termination of this Agreement effective upon
    the expiration of such 30 day period.  Upon the effective date of such
    termination, all rights of St. Mary under this Agreement except as provided
    in Sections 18 and 19 hereof shall terminate and all liabilities and
    obligations of St. Mary hereunder (including the obligation of making any
    further payments under Section 7(b) hereof) shall likewise thereupon
    terminate except as provided in Sections 9(c) and 15(b) hereof.

         (c) St. Mary may also at any time terminate this Agreement as to all
    or any part of the Property by delivering to Owners or by filing for record
    in the appropriate office (with a copy to Owners) a good and sufficient
    Surrender of this Agreement.  Upon mailing, the Surrender to Owners or to
    the appropriate office, all rights of St. Mary under this Agreement shall
    terminate except as provided in Sections 18 and 19 hereof, and all


                                          7

<PAGE>

    liabilities and obligations of St. Mary under this Agreement shall likewise
    terminate except as provided in Sections 9(c) and 15(b) hereof and except
    liability for payments under Section 7(b) hereof that became due prior to
    the date of such termination.

18.      REMOVAL OF PROPERTY.  For a period of six months after the termination
    of this Agreement St. Mary shall have the right (but not the obligation
    except to the extent set forth in Section 9(c) hereof) to remove from the
    Property all buildings, structures, machinery, equipment, personal
    property, fixtures, and improvements owned by St. Mary or erected or placed
    on or in the Property by St. Mary, except mine timbers in place.  St. Mary
    may keep one or more watchmen on the Property during the six- month period.

19.      ACCESS.  For as long as necessary after termination of this Agreement,
    St. Mary shall have the right of access to and across the Property for
    reclamation purposes.

20.      NOTICES.  All notices and other communications to either party shall
    be in writing and shall be sufficiently given if delivered in person or
    sent by certified or registered mail, return receipt requested, addressed

21.      ASSIGNMENT.

         (a)  The rights of either party hereunder may be assigned in whole or
    in part without the consent of the other party hereto, subject to the
    provisions hereinafter set forth.  However, no such assignment shall be
    effective unless and until the assigning party delivers to the
    non-assigning party a written assumption by assignee of all of the
    assignor's duties under this Agreement.

         (b)  No change or division in the ownership of the Property or the
    payments provided for herein, however accomplished, shall enlarge the
    obligations or diminish the rights of St. Mary hereunder.  Owners covenant
    that any change in their ownership shall be accomplished in such a manner
    that St. Mary shall be required to make payments and to give notices to but
    one person, firm, or corporation, and upon breach of this covenant, St.
    Mary may retain all monies otherwise due to Owners until the breach has
    been cured.  No change or division in ownership shall be binding on St.
    Mary until thirty days after Owners have given St. Mary a certified copy of
    the recorded instrument evidencing the change or division.

         (c)  If St. Mary assigns the whole of or an undivided interest in this
    Agreement, liability for breach of any obligation hereunder shall rest
    exclusively upon the holder of the Agreement or of an undivided interest
    herein who commits the breach.  If this Agreement is assigned as to a
    segregated portion of the Property, default by the holder hereunder of that
    portion shall not affect the rights of holders hereunder of any other
    portion.

         (d)  If Owners receive a bona fide written offer from an unrelated
    third party to purchase all or any part of Owners' interest in the Property
    or in this Agreement, Owners shall first offer the interest to St. Mary
    stating the interest proposed to be sold or otherwise disposed of, the
    offering price from such third party and other terms and conditions of
    sale.  St. Mary may accept the offer on the same terms and conditions as
    such third party offer by notice to Owners given within sixty days
    following the effective date Owners' offer.  If St. Mary does not accept
    Owners' offer, Owners may sell or otherwise dispose of the interest offered
    to St. Mary at a price and upon terms and conditions equal to or less
    favorable to the third party than those offered to St. Mary


                                          9

<PAGE>

    provided that the sale or other disposition is effectuated within 120 days
    from the effective date of Owners' offer.  Any sale or other disposition
    shall be subject to the terms of this Agreement, including this subsection
    (d), all of which shall survive the closing, of any such sale in full force
    and effect.  If Owners do not sell or otherwise dispose of the interest
    offered within 120 days, the provisions of this subsection (d) shall apply
    to any subsequent third party offer received by Owners.


22.      NO TRANSFER OR ENCUMBRANCE.  Without St. Mary's prior written consent,
    neither the Owners nor any Owner during term of this Agreement shall (a)
    sell, transfer, assign or convey any interest in the Property except in
    accordance with the provisions of Section 21 (d) hereof; (b) do or fail to
    do any act or thing which would cause or permit any part of the Property to
    be pledged, collateralized or stand as security for any matter whatsoever;
    or (c) enter into any leases or other agreements concerning the Property or
    any part thereof.

23.      FORCE MAJEURE.

         (a)  If St. Mary shall be prevented by Force Majeure from timely
    performance of any of its obligations hereunder (except the payment of
    money to Owners), the failure of performance shall be excused and the
    period for performance and the term of this Agreement shall be extended for
    an additional period equal to the duration of the Force Majeure.  Upon the
    occurrence and upon the termination of any Force Majeure, St. Mary shall
    promptly notify Owners.  St. Mary shall use reasonable diligence to remedy
    a Force Majeure, but shall not be required against its better judgment to
    settle any labor dispute or contest the validity of any law or regulation
    or any action or inaction of civil or military authority.

         (b)  "Force Majeure" means any cause beyond St. Mary's reasonable
    control, including law or regulation; action or inaction of civil or
    military authority; inability to obtain any license, permit, or other
    authorization that may be required to conduct operations on or in
    connection with the Property; unusually severe weather, mining casualty;
    fire; explosion; flood; insurrection; riot; labor dispute; inability after
    diligent


                                          10

<PAGE>

    effort to obtain workmen or material; delay in transportation; acts of God;
    unavailability of a suitable market for the ores, minerals, concentrates,
    or other products from the Property; and excessive costs of mining,
    milling, processing or marketing, or insufficient prices available for the
    ores, minerals, concentrates, or other products produced from the Property,
    which render St. Mary's operations uneconomic.

24.      SHORT FORM.  Contemporaneously herewith, St. Mary and Owners have
    executed and delivered a Short Form of Agreement.  St. Mary may record the
    Short Form or this Agreement, or both, as it may elect.

25.      INUREMENT.  All covenants, conditions, limitations, and provisions
    herein contained apply to and are binding upon the parties hereto, their
    heirs, representatives, successors, and assigns.

26.      MODIFICATION.  No modification, variation, or amendment of this
    Agreement shall be effective unless the modification, variation, or
    amendment is in writing and is signed by Owners and St. Mary.

27.      WAIVER.  No waiver of any breach or default under this Agreement shall
    be effective unless the waiver is in writing and signed by the party
    against whom the waiver is claimed.  No waiver of any breach or default
    shall be deemed to be a waiver of any other or subsequent breach or
    default.

28.      ENTIRE AGREEMENT.  This Agreement sets forth the entire agreement of
    the parties and, except as herein expressly provided, supersedes all
    previous and contemporaneous agreements, representations, warranties, or
    understandings, written or oral.

29.      CONSTRUCTION.  The paragraph headings are for convenience only, and
    shall not be used in the construction of this Agreement.

30.      GOVERNING LAW.  The formation, interpretation, and performance of this
    Agreement shall be governed by the law of the state of Colorado.

31.      TIME OF ESSENCE.  Except as set forth in Section 23 hereof, time is of
    the essence in the performance of each and every term, condition, and
    covenant of this Agreement.

32.      TIME COMPUTATIONS.  In computing the time permitted or required for
    performance or payment as provided hereunder, the first day shall be
    excluded and the last day shall be included.  If the last day of any such
    period is a Saturday, Sunday or legal holiday, the period shall extend to
    include the next day which is not a Saturday, Sunday, or legal holiday.
    Any performance or payment which must be taken or made under this Agreement
    must be taken or made prior to 5:00 p.m. (Denver, Colorado time) of the
    last day of the applicable period provided hereunder for such action,
    unless another time is expressly specified.  All references to time shall be
    Denver, Colorado time.  If a date for performance or payment falls on a
    holiday or weekend, the time for performance or payment shall be extended
    to the next business day, and if performance or payment has occurred on
    such weekend or holiday, it shall be deemed to have occurred on the next
    business day.

33.      INVALIDITY.  The invalidity of any provision of this Agreement shall
    not affect the enforceability of any other provision of this Agreement.

34.      COUNTERPARTS.  This Agreement may be executed in any number of
    counterparts, each of which shall be deemed to be an original and all of
    which together shall constitute one and the same agreement.  If any person
    named as one of the Owners does not execute this Agreement, it nevertheless
    shall be binding upon those persons executing it.

35.      ADDITIONAL DOCUMENTS.  Owners will provide St. Mary with such
    additional documents as may be necessary to carry out the purposes of this
    Agreement.  If conditions change by reason of conveyances, assignments, or
    other matters relating to


                                          12

    the title to or description of the Property, Owners and St. Mary shall
    execute amendments of this Agreement and the Short Form of Agreement, and
    any other documents which may be necessary to reflect such changed
    conditions.


         IN WITNESS WHEREOF, the parties have executed this Agreement as of the
date first above written.

assessment year sending September 1, 1992. For every assessment year 
thereafter in which St. Mary continues this Agreement beyond the 1st day of 
August of any year, St. Mary shall perform assessment work or pay any rental 
fee required by the Department of the Interior. If any court or governmental 
agency decides that the work performed by St. Mary does not constitute the 
kind of work required by federal or state law, St. Mary shall nevertheless be 
deemed to have complied with the terms of this Agreement if the work done by 
St. Mary is the kind generally accepted in the mining industry as assessment 
work under existing law.

     (b) St. Mary shall be relieved of its obligation to perform assessment 
work for any period in which assessment work is not required or is suspended, 
and St. Mary shall have the benefit of subsequent laws enacted which relate 
to assessment work, including any laws extending the time within which to 
perform assessment work. For each year in which St. Mary performs assessment 
work, it will record in the office where the location notice or location 
certificate is recorded, and in any other proper office in the county (or 
recording

                                       10

district) in which the claims are located, and in the proper office of the 
Bureau of Land Management, an affidavit of assessment work or other documents 
complying with the requirements of state law and the Federal land Policy and 
Management Act of 1976 and the regulations implementing and supplementing the 
Act.

     (c) Owners represent that the Property is one contiguous group of mining 
claims, and agree that work on any one or more of the claims will be for the 
benefit of all of the claims. 

     (d) Owners represent that no report of geological, geophysical, and 
geochemical work (30 U.S.C. Sections 28-1 and 28-2) on the Property has been 
filed for assessment years commencing September 1, 1990 and thereafter.

24. ASSIGNMENT.

     (a) The rights of either party hereunder may be assigned in whole or in 
part without the consent of the other party hereto, subject to the provisions 
hereinafter set forth.

     (b) No change or division in the ownership of the Property or the 
payments provided for herein, however accomplished, shall enlarge the 
obligations or diminish the rights of St. Mary hereunder. Owners covenant 
that any change in their ownership shall be

                                       11

<PAGE>

accomplished in such a manner that St. Mary shall be required to make payments 
and to give notices to but one person, firm or corporation, and upon breach of 
this covenant, St. Mary may retain all monies otherwise due to Owners until 
the breach has been cured. No change or division in ownership shall be 
binding on St. Mary until 30 days after Owners have given St. Mary a 
certified copy of the recorded instrument evidencing the change or division.

     (c) If St. Mary assigns the whole of or an undivided interest in this 
Agreement, liability for breach of any obligation hereunder shall rest 
exclusively upon the holder of the Agreement or of an undivided interest 
herein who commits the breach. If this Agreement is assigned as to a 
segregated portion of the Property, default by the holder hereunder of that 
portion shall not affect the rights of holders hereunder of any other portion.

     (d) If Owners receive and propose to accept a bona fide written offer 
from an unrelated third party to purchase, subject to the terms of this 
Agreement, and purpose to accept all or any part of Owners' interest in the 
Property or in this Agreement, Owners shall first offer the interest to St. 
Mary stating the interest proposed to be sold or otherwise disposed of, the 
offering price from such third party and other terms and conditions of sale. 
St. Mary may accept the offer on the same terms and conditions as such third 
party offer by notice to Owners given within 60 days following the date of 
Owners' offer. If St. Mary does not accept Owners' offer, Owners may sell or 
otherwise dispose of the interest offered to St. Mary at a price and upon 
terms and conditions equal to or less favorable to the third party than those 
offered to St. Mary provided that the sale or other disposition is 
effectuated within 120 days from the effective date of Owners' offer. Any 
sale or other disposition shall be subject to the terms of this Agreement, 
including this subsection (d), all of which shall survive the closing of any 
such sale in full force and effect. If Owners do not sell or otherwise 
dispose of the interest offered within 120 days, the provisions of this 
subsection

     (d) shall apply to any subsequent offer received by Owners.

25. NO TRANSFER OR ENCUMBRANCE. Without St. Mary's prior written consent, 
neither Owners nor any Owner during term of this Agreement shall (a) sell, 
transfer, assign or convey any interest in the Property without St. Mary's 
prior written consent or otherwise in

                                       12

<PAGE>

accordance with the provisions of Section 25(d) hereof; (b) do or fail to do 
any act or thing which would cause or permit any part of the Property to be 
pledged, collateralized or stand as security for any matter whatsoever; or 
(c) enter into any leases or other agreements concerning the Property or any 
part thereof.

26. FORCE MAJEURE.

     (a) If St. Mary shall be prevented by Force Majeure from timely 
performance of any of its obligations hereunder (except the payment of money 
to Owners), the failure of performance shall be excused and the period for 
performance and the term of this Agreement shall be extended for an 
additional period equal to the duration of the Force Majeure. Upon the 
occurrence and upon the termination of any Force Majeure, St. Mary shall 
promptly notify Owners. St. Mary shall use reasonable diligence to remedy a 
Force Majeure, but shall not be required against its better judgment to 
settle any labor dispute or contest the validity of any law or regulation or 
any action or inaction of civil or military authority.

     (b) "Force Majeure" means any cause beyond St. Mary's reasonable 
control, including law or regulation, action or inaction of civil or military 
authority, inability to obtain any license, permit, or other authorization 
that may be required to conduct operations on or in connection with the 
Property, unusually severe weather, mining casualty, fire, explosion, 
insurrection, riot, labor dispute, inability after diligent effort to obtain 
workmen or material, delay in transportation and acts of God.

27. SHORT FORM. Contemporaneously herewith, St. Mary and Owners have executed 
and delivered a Short Form of Agreement. St. Mary may record the Short Form 
or this Agreement, or both, as it may elect.

28. INUREMENT. All covenants, conditions, limitations and provisions herein 
contained apply to and are binding upon the parties hereto, their heirs, 
representatives, successors and assigns.

29. MODIFICATION. No modification, variation, or amendment of this Agreement 
shall be effective unless the modification, variation or amendment is in 
writing and is signed by Owners and St. Mary.

30. WAIVER. No waiver of any breach or default under this Agreement shall be 
effective unless the waiver is in writing and signed by the party against 
whom the waiver is claimed. No waiver of any breach or default shall be 
deemed to be a waiver of any other or subsequent breach or default.

parties and, except as herein expressly provided, supersedes all previous and 
contemporaneous agreements, representations, warranties or understandings, 
written or oral.

this Agreement.

35. TIME COMPUTATIONS. In computing the time permitted or required for 
performance or payment as provided hereunder, the first day shall be excluded 
and the last day shall be included. If the last day of any such period is a 
Saturday, Sunday or legal holiday, the period shall extend to include the 
next day which is not a Saturday, Sunday, or legal holiday. Any performance 
or payment which must be taken or made under this Agreement must be taken or 
made prior to 5:00 p.m. (Denver, Colorado time) of the last day of the 
applicable period provided hereunder for such action, unless another time is 
expressly specified. All

<PAGE>

references to time shall be Denver, Colorado time. If a date for performance 
or payment falls on a holiday or weekend, the time for performance or payment 
shall be extended to the next business day, and if performance or payment has 
occurred on such weekend or holiday, it shall be deemed to have occurred on 
the next business day.

36. INVALIDITY. The invalidity of any provision, of this Agreement shall not 
affect the enforceability of any other provision of this Agreement.

37. COUNTERPARTS. This Agreement may be executed in any number of 
counterparts, each of which shall be deemed to be an original and all of 
which together shall constitute one and the same agreement. If any person 
named as one of the Owners does not execute this Agreement, it nevertheless 
shall be binding upon those persons executing it.

38. ADDITIONAL DOCUMENTS. Owners will provide St. Mary with such additional 
documents as may be necessary to carry out the purposes of this Agreement. If 
conditions change by reason of conveyances, assignments or other matters 
relating to the title to or description of the Property, Owners and St. Mary 
shall execute amendments of this Agreement, the Short Form of Option 
Agreement and any other documents which may be necessary to reflect such 
changed conditions.

     IN WITNESS WHEREOF, the parties have executed this Agreement as of
the date first above written.

Mr. Greg Hahn, VP, Minerals Exploration
St. Mary Minerals, Inc.
1776 Lincoln Street, Suite 110
Denver, CO 80203-5400

Dear Greg:

As per our recent phone call, I am herein describing terms of an Agreement, 
which if affirmed by your signature, will result in our passing onto you and 
your company information on an interesting "copper-oxide" prospect 
(prospect), located on claimed land in New Mexico.

The prospect was encountered during a comprehensive review of leachable 
copper reserves in the Southwestern U.S. The prospect was explored during the 
porphyry copper era by a couple of majors, however, was not in itself big 
enough for their further interest. We estimate that there may be upward to 
20-25 million tons of low-grade exotic copper with a possible core area of 
0.5% or better. According to a call made to the owner last year, the 
prospect was open for option negotiations.

Agreement to the following terms would make this prospect and our in-house 
data available to you.

1. St. Mary Minerals, Inc. (St. Mary) would have 60 days from date of 
disclosure of prospect data to accept or reject the prospect. If rejected, 
St. Mary shall submit in writing this rejection and agrees that it and any of 
its officers, employees, agents, representatives or consultants for a period 
of three (3) years from the date of rejection letter, shall not acquire or 
attempt to acquire any interest in the prospect or any property within a mile 
limit outside the boundaries of the prospect (Area to be defined on map with 
data). Furthermore, St. Mary shall keep all data on the prospect strictly 
confidential for the 3-year period.

2. If the prospect is accepted, St. Mary agrees to pay Applied Geologic 
Studies, Inc. (AGS) a discovery bonus amounting to $100,000. The bonus shall 
be paid as follows:

    a. $5,000 at time of land acquisition in prospect area, or in any area 
within a mile limit outside the prospect's boundaries.

<PAGE>

    b. Five percent (5%) of total direct exploration expenditures made for 
benefit of the prospect, exclusive of land costs. Expenditures would include 
geologic work, geochemistry, geophysics, assay, drilling and costs related to 
mine feasibility studies or mine development. These payments would be made 
annually.

    c. Any balance (not to exceed $100,000), shall be paid at time of 
decision to put the prospect into mine production.

3. In the event that St. Mary conveys its interest in the prospect to another 
party, it will require such party to expressly assume in writing St. Mary's 
obligation to make the above payments; whereupon, St. Mary's further 
obligations under this Agreement shall cease. If St. Mary surrenders its 
interest in the prospect, or if St. Mary's rights in the property expire or 
terminate in any other way, it's obligations to make further payments under 
this Agreement shall immediately cease.

If you are in agreement with the terms set forth above, please indicate by 
executing both copies of the Agreement and returning one signed copy to me.

Sincerely,

  William A. Rehrig

Dr. William A. Rehrig
Pres. AGS INC.

                                   SCHEDULE "E"


                   TO THAT CERTAIN AGREEMENT (THE "AGREEMENT")
                MADE AS OF THE 16TH DAY OF NOVEMBER, 1994 BETWEEN
                   SUMMO MINERALS CORPORATION OF THE FIRST PART
                   AND SUMMO USA CORPORATION OF THE SECOND PART
                      (COLLECTIVELY, THE "PAYOR") AND ST. MARY
                    MINERALS INC. OF THE THIRD PART (THE "PAYEE")

                            NET SMELTER RETURNS ROYALTY

1.       In this Agreement, the term "Net Smelter Returns" shall mean the 
gross revenue from the sale by the Payor of all ore, concentrate and metal 
produced from the Property, after deduction of the following:

     (a) all smelting, and refining costs (excluding the cost of SX-EW 
         processing), treatment charges and penalties including but not 
         limited to metal losses, penalties for impurities and charges for 
         refining, selling and handling by the smelter, refinery or other 
         purchaser;

     (b) costs of marketing, handling, transporting and insuring such ore, 
         concentrate or metal from the Property or from a concentrator, 
         whether situated on or off the Property, to a smelter, refinery or 
         other place of treatment or to the purchaser thereof.

2.       Payments of Net Smelter Returns shall be made within 30 days after 
the end of each fiscal quarter in which Net Smelter Returns, as determined on 
the basis of final adjusted invoices, are received by the Payor. All such 
payments shall be made in U.S. dollars.

3.       For the purposes of determining Net Smelter Returns, all receipts 
and disbursements in currency other that U.S. dollars shall be converted into 
U.S. currency on the day of receipt or disbursement, as the case may be.

4.       Each payment of Net Smelter Returns shall be accompanied by a 
statement indicating the calculation of Net Smelter Returns paid. The Payee 
shall be entitled to audit, during normal business hours, such books and 
records as are necessary to determine the correctness of the payments, 
provided however, that such audit shall be made only on an annual basis and 
within 12 months of the end of the fiscal period in respect of which such 
audit is made.

5.       Payment of Net Smelter Returns shall be made to the Payee at such 
place or places in the United States as they shall advise the Payor from 
time to time.

6.       The determination of the Net Smelter Returns hereunder is based on 
the premise that production will be developed solely on the Property. If 
other properties are incorporated with the Property in a single mining 
project and ores pertaining to each cannot be readily

<PAGE>

segregated on a practical or equitable basis, the Payor shall have the right 
to commingle with ore from the Property ore produced from other properties 
owned or controlled by the Payor provided that the Payor will adopt and 
employ generally accepted practices and procedures for weighing, sampling and 
assaying in order to determine the amount of metals or concentrate derived 
from the Property. The Payee, or the representative of the Payee authorized 
in writing, will be permitted to examine at all reasonable times the Payor's 
records pertaining to commingling of ores.

7.       If metal, concentrates or ore shipped from the Property are lost or 
destroyed under circumstances in which the Payor receives payment under an 
insurance policy, such payments will be be deemed Net Smelter Returns.

8.       The Payor shall not sell, assign, transfer or in any other manner 
deal with the Property or any interest therein without the purchaser, 
transferee or assignee acquiring the Property or such interest therein first 
agreeing with the Payor in writing to be bound by the terms of this 
agreement. The Payor's covenant to pay a 1.5% Net Smelter Return Royalty to 
the Payee hereunder shall be a covenant running with the Property.

9.       No error in accounting or in interpretation of this Agreement shall 
be the basis for a claim of breach of fiduciary duty, or the like, or give 
rise to a claim for exemplary or punitive damages or for termination or 
rescission of the Agreement or the estate and rights acquired and held by the 
Payor under the terms of the Agreement.

2.       ESCROW.  Contemporaneously with the execution of this Agreement,
    Owners shall execute, acknowledge, and deliver to the Escrow Agent one or

    action in Owners' name.  Owners agree to cooperate with St. Mary in any
    such action taken.  If the United States or any third person attacks the
    validity of any of the unpatented mining claims included in the Property
    for any reason, St. Mary shall have no obligation to defend the validity of
    the claim.

         (d)  St. Mary shall not be estopped to deny the
    validity of Owners' title.

5.       UNDIVIDED INTEREST.  If the interest claimed by any Owner in any
    portion of the Property is less than one hundred percent, the interest
    claimed by such Owner is set forth in Exhibit A.  Any representation or
    warranty of title made by any Owner shall apply only to the interest set
    forth in Exhibit A.

6.       OPTION PAYMENTS.

    Mary has made an option payment to Owners in the amount of $5,000, receipt
    of which is hereby acknowledged by Owners.

    option payments due Owners hereunder by check which shall be made payable
    to and shall be made payable to and shall be transmitted to the Escrow
    Agent.  The Escrow Instructions to be executed contemporaneously herewith
    will instruct the Escrow Agent how the payments shall be disbursed.  Upon
    making the payments to the Escrow Agent, St. Mary shall be deemed to have
    made the payments to Owners, their heirs, representatives, successors, and
    assigns, and thereupon St. Mary shall be discharged to the extent thereof
    as if the payments had been made directly to Owners, or to any person, firm
    or corporation entitled thereto, and St. Mary shall not be liable for the
    ultimate distribution or receipt of any payment or payments.

8.       OPERATIONS.

         (a)  SCOPE.  During the term of this Agreement, St. Mary shall have
    free and unrestricted access to the Property, and shall have the right and
    privilege of conducting exploratory investigations and prospecting for
    mineral deposits on the Property, effective during the life of the Option,
    and that prospecting shall include, but not be limited to, soil testing,
    geophysical surveys, core drilling, shaft sinking, tunnel and mine building
    and the removal of ore for testing purposes but not removal of ore for
    sale.  St. Mary shall have the right to erect and maintain upon the
    Property any improvements, structures or facilities including mines, shafts
    and tunnels as may be necessary or convenient for the conduct of its
    operations.

         (b)  STANDARDS OF OPERATION.  St. Mary shall conduct all operations on
    the Property in a good and workmanlike manner and in accordance with
    accepted mining practice.

         (c)  COMPLIANCE WITH LAW: RECLAMATION: St. Mary shall endeavor in good
    faith to comply with applicable provisions of federal, state and local laws
    and regulations, as required by the operating permits issued to St. Mary by
    these agencies under which St. Mary shall conduct its operations.  If this
    Agreement is terminated, St. Mary shall reclaim only those portions of the
    Property disturbed by its operations, and in compliance with all applicable
    governmental laws, regulations and orders.  St. Mary shall have the right,
    without payment of any additional consideration to Owners, to enter upon
    the Property subsequent to termination of this Agreement for purposes of
    performing such reclamation work.

9.       NO IMPLIED COVENANTS.  No covenants or conditions relating to the
    exploration or related operations on or in connection with the Property, or
    the timing thereof, other than those expressly provided in this Agreement,
    shall be implied.  After commencing any exploration or related operations
    on or in connection with the Property and so long as this Agreement has not
    been terminated before the expiration of its term, St. Mary may in its sole
    discretion curtail or cease such operations so long as it continues to make
    any payments due Owners under this Agreement subject to the provisions of
    Section 16 hereof.

10.      PROTECTION FROM LIENS AND DAMAGES.  St. Mary shall keep the Property
    free of liens for labor performed or materials or merchandise furnished for
    use on the Property under this Agreement, and shall hold Owners harmless
    from all costs, loss, or damage which may result from any work or
    operations of St. Mary or its occupancy of the Property.

11.      TAXES.  Owners shall pay all taxes levied against the Property prior
    to the date of this Agreement.  St. Mary shall pay or reimburse Owners for
    all taxes levied against the Property during the term of this Agreement.
    In the case of taxes for the calendar year in which this Agreement
    commences, and for the calendar year in which this Agreement ends, there
    shall be an apportionment between the parties, St. Mary to bear the
    proportion of taxes upon the Property applicable to the part of the
    calendar year included hereunder, and Owners to bear the balance of the
    taxes.  St. Mary shall pay all taxes levied during the term of this
    Agreement against all buildings, structures, machinery, equipment, personal
    property, fixtures, and improvements placed upon the Property by St. Mary,
    and all taxes levied against St. Mary as an employer of labor.  All taxes
    shall be paid when due and before delinquent, but St. Mary shall be under
    no obligation to pay any tax so long as the tax is being contested in good
    faith and by appropriate legal proceedings and the nonpayment thereof does
    not adversely affect any right, title, or interest of Owners in or to the
    Property.

12.      INSURANCE.  St. Mary shall carry at all times during the term of this
    Agreement worker's compensation and other insurance required by state laws
    and mining regulations, or St. Mary may self-insure as to such matters if
    it qualifies as a self-insurer under the appropriate laws and regulations.

13.      INSPECTION.

         (a)  Owners or their authorized representative may enter on the
    Property at any reasonable time for the purpose of inspection, but shall
    enter at Owners' own risk and so as not to hinder unreasonably the
    operations of St. Mary.  Owners shall indemnify and hold St. Mary harmless
    from any damage, claim, or demand by reason of injury to or the presence of
    Owners, their agents or representatives on the Property.

         (b)  Owners or their authorized representative may, at any reasonable
    time, inspect any records pertinent and necessary for substantiating the
    compliance of St. Mary with the provisions of this Agreement.

    of its exploration work under this Agreement and which are then in St.
    Mary's possession or control.  Upon Owners' request made within ninety (90)
    days after termination of this Agreement, St. Mary shall at Owners'
    expense, provide Owners with the drill core or cuttings designated by
    Owners and with copies of any portion of the factual geological and
    geophysical data and maps (not including interpretive data), logs of drill
    holes, and results of assaying and sampling designated by Owners.  St. Mary
    makes no representation or warranty as to the accuracy or completeness of
    any such data or information, and shall not be liable on account of any use
    by Owners or any other person of any such data or information.  St. Mary
    shall not be liable for the loss or destruction of any drill core or
    cuttings.

15.      CONFIDENTIALITY.  During the term of this Agreement all information
    obtained by Owners or their authorized representatives from St. Mary or
    arising out of St. Mary's activities on the Property pursuant to this
    Agreement shall be kept strictly confidential by Owners and shall not be
    released to any third party except with the prior written consent of St.
    Mary.

    (21) years from the date hereof unless sooner surrendered or otherwise

         (b)  It is also agreed that a failure by St. Mary to make an option
    payment within 60 days of the due date therefor as provided in Section 6(b)
    hereof shall constitute also a termination of this Agreement effective upon
    the expiration of such 60 day period.  Upon the effective date of such

    facilities necessary or convenient for St. Mary's operations on the
    Property or on other property.

20.      AMENDMENT RELOCATIONS AND PATENTS.  During the term of this Agreement,
    St. Mary shall have the right (but not the obligation), in the name of
    Owners, to amend or relocate any or all of the unpatented mining claims
    included in the Property, to locate placer claims on ground theretofore
    covered by lode claims and vice versa, and to locate any millsites on
    ground theretofore covered by mining claims and vice versa, and to locate
    any fractions resulting from the location, amendment or relocations of
    mining claims or millsites.  At the request of St. Mary, Owners shall apply
    for a patent for any or all of the unpatented mining claims and millsites.
    For purposes of implementing the provisions of the Section, Owners do
    hereby nominate, constitute and appoint St. Mary as their true and lawful
    attorney-in-fact to execute, deliver and record on behalf of the Owners and

    the assessment year ending September 1, 1992, and that the rental fee
    required by the Department of the Interior was paid for the assessment year
    ending September 1, 1993.  For every assessment year thereafter in which
    St. Mary continues this Agreement beyond the 1st day of August of any year,
    St. Mary shall perform assessment work or pay any rental fee required by
    the Department of the Interior.  If any court or governmental agency
    decides that the work performed by St. Mary does not constitute the kind of
    work required by federal or state law, St. Mary shall nevertheless be
    deemed to have complied with the terms of this Agreement if the work done
    by St. Mary is the kind generally accepted in the mining industry as
    assessment work under existing law.

         (b)  St. Mary shall be relieved of its obligation to perform
    assessment work for any period in which assessment work is not required or
    is suspended, and St. Mary shall have the benefit of subsequent laws

    time within which to perform assessment work.  For each year in which St.
    Mary performs assessment work, it  will record in the office where the
    location notice or location certificate is recorded, and in any other
    proper office in the county (or recording district) in which the claims are
    located, and in the proper office of the Bureau of Land Management, an
    affidavit of assessment work or other documents complying with the
    requirements of state law and the Federal land Policy and Management Act of
    1976 and the regulations implementing and supplementing the Act.

                        Attn: Gregory A. Hahn

24.      ASSIGNMENT.

         (a)  The rights of either party hereunder may be assigned in whole or
    in part without the consent of the other party hereto, subject to the
    provisions hereinafter set forth.

         (b)  No change or division in the ownership of the Property or the
    payments provided for herein, however accomplished, shall enlarge the
    obligations or diminish the rights of St. Mary hereunder.  Owners covenant
    that any change in their ownership shall be accomplished in such a manner
    that St. Mary shall be required to make payments and to give notices to but
    one person, firm, or corporation, and upon breach of this covenant,


                                          11

<PAGE>

    St. Mary may retain all monies otherwise due to Owners until the breach has
    been cured.  No change or division in ownership shall be binding on St.
    Mary until thirty days after Owners have given St. Mary a certified copy of
    the recorded instrument evidencing the change or division.

         (c)  If St. Mary assigns the whole of or an undivided interest in this
    Agreement, liability for breach of any obligation hereunder shall rest
    exclusively upon the holder of the Agreement or of an undivided interest
    herein who commits the breach.  If this Agreement is assigned as to a
    segregated portion of the Property, default by the holder hereunder of that
    portion shall not affect the rights of holders hereunder of any other
    portion.

         (d)  If Owners receive a bona fide written offer from an unrelated
    third party to purchase all or any part of Owners' interest in the Property
    or in this Agreement, Owners shall first offer the interest to St. Mary
    stating the interest proposed to be sold or otherwise disposed of, the
    offering price from such third party and other terms and conditions of
    sale.  St. Mary may accept the offer on the same terms and conditions as
    such third party offer by notice to Owners given within sixty days
    following the effective date Owners' offer.  If St. Mary does not accept
    Owners' offer, Owners may sell or otherwise dispose of the interest offered
    to St. Mary at a price and upon terms and conditions equal to or less
    favorable to the third party than those offered to St. Mary provided that
    the sale or other disposition is effectuated within 120 days from the
    effective date of Owners' offer.  Any sale or other disposition shall be
    subject to the terms of this Agreement, including this subsection (d), all
    of which shall survive the closing of any such sale in full force and
    effect.  If Owners do not sell or otherwise dispose of the interest offered
    within 120 days, the provisions of this subsection (d) shall apply to any
    subsequent third party offer received by Owners.


25.      NO TRANSFER OR ENCUMBRANCE.  Without St. Mary's prior written consent,
    neither the Owners nor any Owner during term of this Agreement shall (a)
    sell, transfer, assign or convey any interest in the Property without St.
    Mary's prior written consent or otherwise in accordance with the provisions
    of Section 21(d) hereof; (b) do or fail to do


                                          12

<PAGE>

    any act or thing which would cause or permit any part of the Property to be
    pledged, collateralized or stand as security for any matter whatsoever; or
    (c) enter into any leases or other agreements concerning the Property or
    any part thereof.

26.      FORCE MAJEURE.

         (a)  If St. Mary shall be prevented by Force Majeure from timely
    performance of any of its obligations hereunder (except the payment of
    money to Owners), the failure of performance shall be excused and the
    period for performance and the term of this Agreement shall be extended for
    an additional period equal to the duration of the Force Majeure.  Upon the
    occurrence and upon the termination of any Force Majeure, St. Mary shall
    promptly notify Owners.  St. Mary shall use reasonable diligence to remedy
    a Force Majeure, but shall not be required against its better judgment to
    settle any labor dispute or contest the validity of any law or regulation
    or any action or inaction of civil or military authority.

         (b)  "Force Majeure" means any cause beyond St. Mary's reasonable
    control, including law or regulation; action or inaction of civil or
    military authority; inability to obtain any license, permit, or other
    authorization that may be required to conduct operations on or in
    connection with the Property; unusually severe weather; mining casualty;
    fire; explosion; flood; insurrection; riot; labor dispute; inability after
    diligent effort to obtain workmen or material; delay in transportation;
    acts of God; unavailability of a suitable market for the ores, minerals,
    concentrates, or other products from the Property; and excessive costs of
    mining, milling, processing or marketing, or insufficient prices available
    for the ores, minerals, concentrates, or other products produced from the
    Property, which render St. Mary's operations uneconomic.

27.      SHORT FORM.  Contemporaneously herewith, St. Mary and Owners have
    executed and delivered a Short Form of Agreement.  St. Mary may record the
    Short Form or this Agreement, or both, as it may elect.

         WHEREAS, Owners are the owners of certain unpatented mining claims

more particularly described on EXHIBIT B attached hereto and made a part 
hereof; and

         WHEREAS, St. Mary desires to carry out exploration work and to acquire
an option to purchase the Property,

         WHEREAS, Owners desire to make the Property available for the conduct
by St. Mary of certain mineral exploration work thereon and to grant St. Mary
the option to purchase the Property,

         NOW THEREFORE, in consideration of Ten Dollars ($10.00) in hand paid
to Owners, the receipt and sufficiency of which are hereby acknowledged, and
further in consideration of the mutual covenants, agreements, and promises
herein contained, the parties agree as follows:


1.       OPTION. Owners grant to St. Mary during the term of this Agreement the
    sole and exclusive option (the "Option") to purchase the Property, together
    with all appurtenances and water rights incident thereto and all
    improvements and personal property thereon, free and clear of all liens and
    encumbrances, for a total purchase price of Five Hundred Thousand Dollars
    ($500,000.00). St. Mary shall be entitled to a credit against the purchase

    hereof.  If the Property is


<PAGE>

    placed in commercial production at any time during the term of this
    Agreement, St. Mary shall exercise the option by providing written notice
    of exercise to Owners.  Within three (3) years after such notice, but no
    later than August 1, 2015, St. Mary shall deliver the balance of the
    purchase price to Owners. "Commercial production" shall mean the processing
    and sale of ores, concentrates, metals and other mineral products which
    have been mined on the Property but which shall not include processing for
    the purpose of testing or milling by a pilot plant.

2.       ESCROW. Contemporaneously with the execution of this Agreement, Owners
    shall execute, acknowledge, and deliver to the Escrow Agent one or more
    general warranty deeds conveying the Property to St. Mary in the form
    (without legal descriptions) of Exhibit C attached hereto and incorporated
    herein.
         Owners and St. Mary hereby appoint CB&S Nominee Corporation, 1800 One

    Instructions executed contemporaneously herewith.

3.       EXCLUSIVE POSSESSION. St. Mary shall have the exclusive possession of
    the Property during the term of this Agreement.


4.       TITLE.

         (a)  Owners warrant that they are in possession of the Property, that
    they have the right to enter into this Agreement, that they know of no
    other person claiming any interest in the Property or the ground covered
    thereby, and that the Property is free from all liens and encumbrances,
    except liens for property taxes not yet due and payable.  Owners further
    warrant to St. Mary the quiet enjoyment of the Property and the right to
    explore, develop, and mine the same.

         (b)  Owners warrant and will defend title of the property against all
    persons whomsoever.

<PAGE>


         (c)  At St. Mary's request, Owners shall take all action necessary
    (including judicial proceedings) to remove any cloud from or cure any
    defect in their title to the Property or the ground covered thereby.  If
    Owners fail or refuse to take any such action, St. Mary may take any such
    action in Owners' name.  Owners agree to cooperate with St. Mary in any
    such action taken.  If the United States or any third person attacks the
    validity of any of the unpatented mining claims included in the Property
    for any reason, St. Mary shall have no obligation to defend the validity of
    the claim.

         (d) St. Mary shall not be estopped to deny the validity of Owners'
    title.

5.       UNDIVIDED INTEREST. If the interest claimed by any Owner in any
    portion of the Property is less than one hundred percent, the interest
    claimed by such Owner is set forth in Exhibit A. Any representation or
    warranty of title made by any Owner shall apply only to the interest set
    forth in Exhibit A.

6.       OPTION PAYMENTS.

    Mary has made an option payment to Owners in the amount of $5,000, receipt
    of which is hereby acknowledged by Owners.

24.      ASSIGNMENT.

         (a)  The rights of either party hereunder may be assigned in whole or
    in part without the consent of the other party hereto, subject to the
    provisions hereinafter set forth.

         (b)  No change or division in the ownership of the Property or the
    payments provided for herein, however accomplished, shall enlarge the
    obligations or diminish the rights of St. Mary hereunder.  Owners covenant
    that any change in their ownership shall be accomplished in such a manner
    that St. Mary shall be required to make payments and to give notices to but
    one person, firm, or corporation, and upon breach of this covenant,


                                          11

<PAGE>

    St. Mary may retain all monies otherwise due to Owners until the breach has
    been cured.  No change or division in ownership shall be binding on St.
    Mary until thirty days after Owners have given St. Mary a certified copy of
    the recorded instrument evidencing the change or division.

         (c)  If St. Mary assigns the whole of or an undivided interest in this
    Agreement, liability for breach of any obligation hereunder shall rest
    exclusively upon the holder of the Agreement or of an undivided interest
    herein who commits the breach.  If this Agreement is assigned as to a
    segregated portion of the Property, default by the holder hereunder of that
    portion shall not affect the rights of holders hereunder of any other
    portion.

         (d)  If 0wners receive a bona fide written offer from an unrelated
    third party to purchase all or any part of Owners' interest in the Property
    or in this Agreement, Owners shall first offer the interest to St. Mary
    stating the interest proposed to be sold or otherwise disposed of, the
    offering price from such third party and other terms and conditions of
    sale. St. Mary may accept the offer on the same terms and conditions as
    such third party offer by notice to Owners given within sixty days
    following the effective date Owners' offer.  If St. Mary does not accept
    Owners' offer, Owners may sell or otherwise dispose of the interest
    offered to St. Mary at a price and upon terms and conditions equal to or
    less favorable to the third party than those offered to St. Mary provided
    that the sale or other disposition is effectuated within 120 days from the
    effective date of Owners' offer.  Any sale or other disposition shall be
    subject to the terms of this Agreement, including this subsection (d), all
    of which shall survive the closing of any such sale in full force and
    effect.  If Owners do not sell or otherwise dispose of the interest offered
    within 120 days, the provisions of this subsection (d) shall apply to any
    subsequent third party offer received by Owners.



25.      NO TRANSFER OR ENCUMBRANCE.  Without St. Mary's prior written consent,
    neither the Owners nor any Owner during term of this Agreement shall (a)
    sell, transfer, assign or convey any interest in the Property without St.
    Mary's prior written consent or otherwise in accordance with the provisions
    of Section 21(d) hereof; (b) do or fail to do


                                          12

<PAGE>

    any act or thing which would cause or permit any part of the Property to
    be pledged, collateralized or stand as security for any matter whatsoever;
    or (c) enter into any leases or other agreements concerning the Property or
    any part thereof.


26.      FORCE MAJEURE.

         (a) If St. Mary shall be prevented by Force Majeure from timely
    performance of any of its obligations hereunder (except the payment of
    money to Owners), the failure of performance shall be excused and the
    period for performance and the term of this Agreement shall be extended
    for an additional period equal to the duration of the Force Majeure. Upon
    the occurrence and upon the termination of any Force Majeure, St. Mary
    shall promptly notify Owners.  St. Mary shall use reasonable diligence to
    remedy a Force Majeure, but shall not be required against its better
    judgment to settle any labor dispute or contest the validity of any law or
    regulation or any action or inaction of civil or military authority.

         (b) "Force Majeure" means any cause beyond St. Mary's reasonable
    control, including law or regulation; action or inaction of civil or
    military authority; inability to obtain any license, permit, or other
    authorization that may be required to conduct operations on or in
    connection with the Property; unusually severe weather; mining casualty; 
    fire; explosion; flood; insurrection; riot; labor dispute; inability after
    diligent effort to obtain workmen or material; delay in transportation;
    acts of God; unavailability of a suitable market for the ores, minerals,
    concentrates, or other products from the Property; and excessive costs of
    mining, milling, processing or marketing, or insufficient prices available
    for the ores, minerals, concentrates, or other products produced from the
    Property, which render St. Mary's operations uneconomic.

27.      SHORT FORM. Contemporaneously herewith, St. Mary and Owners have
    executed and delivered a Short Form of Agreement. St. Mary may record the
    Short Form or this Agreement, or both, as it may elect.

   November 16, 1994


                      EXPLORATION AND PURCHASE OPTION AGREEMENT



         THIS OPTION AGREEMENT ("Agreement") made effective as of the 1st day

shown on EXHIBIT A attached hereto and made a part hereof (individually an
"Owner" and collectively the "Owners") and ST. MARY MINERALS INC., a Colorado
corporation, whose address is 1776 Lincoln Street, Denver, Colorado 80203
(hereinafter referred to as "St. Mary");

         WHEREAS, Owners are the owners of certain patented mining claims and
millsites situate in Taos County, New Mexico, herein referred to as "the
Property," and more particularly described on EXHIBIT B attached hereto and made
a part hereof; and

         WHEREAS, St. Mary desires to carry out exploration work and to acquire
an option to purchase the Property,

         WHEREAS, Owners desire to make the Property available for the conduct
by St. Mary of certain mineral exploration work thereon and to grant St. Mary
the option to purchase the Property,

         NOW THEREFORE, in consideration of Ten Dollars ($10.00) in hand paid
to Owners, the receipt and sufficiency of which are hereby acknowledged, and 
further in consideration of the mutual covenants, agreements, and promises 
herein contained, the parties agree as follows:

1.       OPTION. Owners grant to St. Mary during the term of this Agreement the
    sole and exclusive option (the "Option") to purchase the Property, together
    with all appurtenances and water rights incident thereto and all 
    improvements and personal property thereon, free and clear of all 
    liens and encumbrances, for a total purchase price of Five Hundred 
    Thousand Dollars ($500,000.00). St. Mary shall be entitled to a credit 
    against the purchase price for all amounts paid under the provisions of 
    Section 6. hereof and for all costs and expenses incurred under the 
    provisions of Section 4 hereof. If the Property is


<PAGE>

    placed in commercial production at any time during the term of this
    Agreement, St. Mary shall exercise the option by providing written notice
    of exercise to Owners.  Within three (3) years after such notice, but no
    later than August 1, 2015, St. Mary shall deliver the balance of the
    purchase price to Owners.  "Commercial production" shall mean the
    processing and sale of ores, concentrates, metals and other mineral
    products which have been mined on the Property but which shall not include
    processing for the purpose of testing or milling by a pilot plant.


2.       ESCROW.  Contemporaneously with the execution of this Agreement,
    Owners shall execute, acknowledge, and deliver to the Escrow Agent one or
    more general warranty deeds conveying the Property to St. Mary in the form
    (without legal descriptions) of Exhibit C attached hereto and
    incorporated herein.
         Owners and St. Mary hereby appoint CB&S Nominee Corporation, 1800 One
    Norwest Center Building, 1700 Lincoln Street, Denver, Colorado 80203 as
    their Escrow Agent to receive and distribute all payments and to hold the
    deed and deliver it to the party entitled hereunder to receive the same.
    The parties hereto agree that the Escrow Agent shall act pursuant to Escrow
    Instructions executed contemporaneously herewith.


3.       EXCLUSIVE POSSESION.  St. Mary shall have the exclusive possession of
    the Property during the term of this Agreement.


4.       TITLE.

         (a) Owners warrant that they are in possession of the Property, that
    they have the right to enter into this Agreement, that they know of no
    other person claiming any interest in the Property or the ground covered
    thereby, and that the Property is free from all liens and encumbrances,
    except liens for property taxes not yet due and payable.  Owners further
    warrant to St. Mary the quiet enjoyment of the Property and the right to
    explore, develop, and mine the same.

         (b)  Owners warrant and will defend title of the property against all
    persons whomsoever.


                                          2

<PAGE>

         (c)  At St. Mary's request, Owners shall take all action necessary
    (including judicial proceedings) to remove any cloud from or cure any
    defect in their title to the Property or the ground covered thereby.  If
    Owners fail or refuse to take any such action, St. Mary may take any such
    action in Owners' name.  Owners agree to cooperate with St. Mary in
    any such action taken.  If the United States or any third person attacks
    the validity of any of the patented mining claims included in the Property
    for any reason, St. Mary shall have no obligation to defend the validity of
    the claim.

         (d)  St. Mary shall not be estopped to deny the validity of Owners'
    title.


5.       UNDIVIDED INTEREST.  If the interest claimed by any Owner in any
    portion of the Property is less than one hundred percent, the interest
    claimed by such Owner is set forth in Exhibit A.  Any representation or
    warranty of title made by any Owner shall apply only to the interest set
    forth in Exhibit A.

    Mary has made an option payment to Owners in the amount of $5,000, receipt

<PAGE>

            (b)      STANDARDS OF OPERATION.  St. Mary shall conduct all 
    operations on the Property in a good and workmanlike manner and in 
    accordance with accepted mining practice.

            (c)      COMPLIANCE WITH LAW; RECLAMATION:  St. Mary shall 
    endeavor in good faith to comply with applicable provisions of federal, 
    state and local laws and regulations, as required by the operating

    conduct its operations.  If this Agreement is terminated, St. Mary shall 
    reclaim only those portions of the Property disturbed by its operations, 
    and in compliance with all applicable governmental laws, regulations and 
    orders. St. Mary shall have the right, without payment of any additional 
    consideration to Owners, to enter upon the Property subsequent to 
    termination of this Agreement for purposes of performing such 
    reclamation work.


9.       NO IMPLIED COVENANTS.  No covenants or conditions relating to the
    exploration or related operations on or in connection with the Property, or
    the timing thereof, other than those expressly provided in this Agreement,
    shall be implied.  After commencing any exploration or related operations
    on or in connection with the Property and so long as this Agreement has not
    been terminated before the expiration of its term, St. Mary may in its sole
    discretion curtail or cease such operations so long as it continues to make
    any payments due Owners under this Agreement subject to the provisions of 
    Section 16 hereof.



10.      PROTECTION FROM LIENS AND DAMAGES.  St. Mary shall keep the Property
    free of liens for labor performed or materials or merchandise furnished for
    use on the Property under this Agreement, and shall hold Owners harmless

    operations of St. Mary or its occupancy of the Property.

11.      TAXES.  Owners shall pay all taxes levied against the Property prior
    to the date of this Agreement.  St. Mary shall pay or reimburse Owners for
    all taxes levied against the Property during the term of this Agreement. 
    In the case of taxes for the calendar year in which this Agreement
    commences, and for the calendar year in which this Agreement ends, there
    shall be an apportionment between the parties, St. Mary to bear the
    proportion of taxes upon the Property applicable to the part of the
    calendar year included hereunder, and Owners to bear the balance of the
    taxes.  St. Mary shall pay all taxes levied during the term of this
    Agreement against all buildings, structures, machinery, equipment, personal
    property, fixtures, and improvements placed upon the Property by St. Mary,
    and all taxes levied against St. Mary as an employer of labor.  All taxes
    shall be paid when due and before delinquent, but St. Mary shall be under
    no obligation to pay any tax so long as the tax is being contested in good
    faith and by appropriate legal proceedings and the nonpayment thereof does
    not adversely affect any right, title, or interest of Owners in or to the
    Property.


12.      INSURANCE.  St. Mary shall carry at all times during the term of this
    Agreement worker's compensation and other insurance required by state laws
    and mining regulations, or St. Mary may self-insure as to such matters if
    it qualifies as a self-insurer under the appropriate laws and regulations.


13.      INSPECTION.

         (a)  Owners or their authorized representative may enter on the
    Property at any reasonable time for the purpose of inspection, but shall
    enter at Owners' own risk and so as not to hinder unreasonably the
    operations of St. Mary.  Owners shall indemnify and hold St. Mary harmless
    from any damage, claim, or demand by reason of injury to or the presence of
    Owners, their agents or representatives on the Property.

         (b)  Owners or their authorized representative may, at any reasonable
    time, inspect any records pertinent and necessary for substantiating the
    compliance of St. Mary with the provisions of this Agreement.

    data concerning the Property (or copies thereof) which are in Owners'
    possession or control.

         (b)  Upon the surrender or other termination of this Agreement (except

    provided in Section 6 hereof), St. Mary shall, within sixty days after
    termination, (i) return to Owners all drill core and original data

    provide Owners with the drill core or cuttings designated by Owners and
    with copies of any portion of the factual geological and geophysical data
    and maps (not including interpretive data), logs of drill holes, and
    results of assaying and sampling designated by Owners.  St. Mary makes no
    representation or warranty as to the accuracy or completeness of any such
    data or information, and shall not be liable on account of any use by
    Owners or any other person of any such data or information.  St. Mary shall
    not be liable for the loss or destruction of any drill core or cuttings.


15.      CONFIDENTIALITY.  During the term of this Agreement all information
    obtained by Owners or their authorized representatives from St. Mary or
    arising out of St. Mary's activities on the Property pursuant to this
    Agreement shall be kept strictly confidential by Owners and shall not be
    released to any third party except with the prior written consent of St.
    Mary.

         (a)  The term of this Agreement shall be for a period of twenty-one
    (21) years from the date hereof unless sooner surrendered or otherwise
    terminated, or until the earlier exercise of the Option.

         (b)  It is also agreed that a failure by St. Mary to make an option
    payment within 60 days of the due date therefor as provided in Section 6(b)
    hereof shall constitute a termination of this Agreement effective upon the
    expiration of such 60 day period.  Upon the effective date of such
    termination, all rights of St. Mary under this Agreement except as provided
    in Sections 17 and 18 hereof shall terminate and all liabilities and
    obligations of St. Mary hereunder (including the obligation of making any
    further payments under Section 6(b) hereof) shall likewise thereupon
    terminate except as provided in Sections 8(c) and 14(b) hereof.

         (c)  St. Mary may also at any time terminate this Agreement as to all
    or any part of the Property by delivering to Owners or by filing for record
    in the appropriate office (with a copy to Owners) a good and sufficient
    Surrender of this Agreement.  Upon mailing the Surrender to Owners or to
    the appropriate office, all rights of St. Mary under this Agreement shall
    terminate except as provided in Sections 17 and 18 hereof, and all
    liabilities and obligations of St. Mary under this Agreement shall likewise
    terminate except as provided in Sections 8(c) and 14(b) hereof and except
    liability for payments under Section 6(b) hereof that became due prior to
    the date of such termination.


17.      REMOVAL OF PROPERTY.  For a period of six months after the termination
    of this Agreement St. Mary shall have the right (but not the obligation
    except to the extent set forth in Section 8(c) hereof) to remove from the
    Property all buildings, structures, machinery, equipment, personal
    property, fixtures, and improvements owned by St. Mary or erected or placed
    on or in the Property by St. Mary, except mine timbers in place.  St. Mary
    may keep one or more watchmen on the Property during the six-month period.


18.      ACCESS.  For as long as necessary after termination of this Agreement,
    St. Mary shall have the right of access to and across the Property for
    reclamation purposes.

                             Attn: Gregory A. Hahn


21.      ASSIGNMENT.

         (a)  The rights of either party hereunder may be assigned in whole or
    in part without the consent of the other party hereto, subject to the
    provisions hereinafter set forth.

         (b)  No change or division in the ownership of the Property or the
    payments provided for herein, however accomplished, shall enlarge the
    obligations or diminish the rights of St. Mary hereunder.  Owners covenant
    that any change in their ownership shall


                                          9

<PAGE>

    be accomplished in such a manner that St. Mary shall be required to
    make payments and to give notices to but one person, firm, or corporation,
    and upon breach of this covenant, St. Mary may retain all monies otherwise
    due to Owners until the breach has been cured.  No change or division in
    ownership shall be binding on St. Mary until thirty days after Owners have
    given St. Mary a certified copy of the recorded instrument evidencing the
    change or division.

         (c) If St. Mary assigns the whole of or an undivided interest in this
    Agreement, liability, for breach of any obligation hereunder shall rest
    exclusively upon the holder of the Agreement or of an undivided interest
    herein who commits the breach.  If this Agreement is assigned as to a
    segregated portion of the Property, default by the holder hereunder of that
    portion shall not affect the rights of holders hereunder of any other
    portion.

         (d)  If Owners receive a bona fide written offer from an unrelated 
    third party to purchase all or any part of Owners' interest in the 
    Property or in this Agreement, Owners shall first offer the interest to 
    St. Mary stating the interest proposed to be sold or otherwise disposed 
    of, the offering price from such third party and other terms and 
    conditions of sale.  St. Mary may accept the offer on the same terms and 
    conditions as such third party offer by notice to Owners given within 
    sixty days following the effective date Owners' offer. If St. Mary does 
    not accept Owners' offer, Owners may sell or otherwise dispose of the 
    interest offered to St. Mary at a price and upon terms and conditions 
    equal to or less favorable to the third party than those offered to St. 
    Mary provided that the sale or other disposition is effectuated within 
    120 days from the effective date of Owners' offer.  Any sale or other 
    disposition shall be subject to the terms of this Agreement, including 
    this subsection (d), all of which shall survive the closing of any such 
    sale in full force and effect.  If Owners do not sell or otherwise 
    dispose of the interest offered within 120 days, the provisions of this 
    subsection (d) shall apply to any subsequent third party offer received 
    by Owners.
    
22.      NO TRANSFER OR ENCUMBRANCE.  Without St. Mary's prior written consent,
    neither the Owners nor any Owner during term of this Agreement shall 
    (a) sell, transfer, assign


                                          10

<PAGE>

    or convey any interest in the Property without St. Mary's prior
    written consent or otherwise in accordance with the provisions of Section
    21(d) hereof; (b) do or fail to do any act or thing which would cause or
    permit any part of the Property to be pledged, collateralized or stand as
    security for any matter whatsoever; or (c) enter into any leases or other
    agreements concerning the Property or any part thereof.


23.      FORCE MAJEURE.

         (a)  If St. Mary shall be prevented by Force Majeure from timely
    performance of any of its obligations hereunder (except the payment of
    money to Owners), the failure of performance shall be excused and the
    period for performance and the term of this Agreement shall be extended for
    an additional period equal to the duration of the Force Majeure.  Upon the
    occurrence and upon the termination of any Force Majeure, St. Mary shall
    promptly notify Owners.  St. Mary shall use reasonable diligence to remedy
    a Force Majeure, but shall not be required against its better judgment to
    settle any labor dispute or contest the validity of any law or regulation
    or any action or inaction of civil or military authority.

         (b) "Force Majeure" means any cause beyond St. Mary's reasonable
    control, including law or regulation; action or inaction of civil or
    military authority; inability to obtain any license, permit, or other
    authorization that may be required to conduct operations on or in
    connection with the Property; unusually severe weather; mining casualty;
    fire; explosion; flood; insurrection; riot; labor dispute; inability after
    diligent effort to obtain workmen or material; delay in transportation;
    acts of God; unavailability of a suitable market for the ores, minerals,
    concentrates, or other products from the Property; and excessive costs of
    mining, milling, processing or marketing, or insufficient prices available
    for the ores, minerals, concentrates, or other products produced from the
    Property, which render St. Mary's operations uneconomic.


24.      SHORT FORM.  Contemporaneously herewith, St. Mary and Owners have
    executed and delivered a Short Form of Agreement.  St. Mary may record the
    Short Form or this Agreement, or both, as it may elect.


                                          11

    herein contained apply to and are binding upon the parties hereto, their

    Agreement shall be effective unless the modification, variation, or
    amendment is in writing and is signed by Owners and St. Mary.

27.      WAIVER.  No waiver of any breach or default under this Agreement shall
    be effective unless the waiver is in writing and signed by the party
    against whom the waiver is claimed.  No waiver of any breach or default
    shall be deemed to be a waiver of any other or subsequent breach or
    default.


28.      ENTIRE AGREEMENT.  This Agreement sets forth the entire agreement of
    the parties and, except as herein expressly provided, supersedes all
    previous and contemporaneous agreements, representations, warrantees, or
    understandings, written or oral.

    shall not be used in the construction of this Agreement.

    Agreement shall be governed by the law of the state of Colorado.


31.      TIME OF ESSENCE.  Except as set forth in Section 23 hereof, time is of
    the essence in the performance of each and every term, condition, and
    covenant of this Agreement.


32.      TIME COMPUTATIONS.  In computing the time permitted or required for
    performance or payment as provided hereunder, the first day shall be
    excluded and the last day shall be included.  If the last day of any such
    period is a Saturday, Sunday or legal holiday, the period shall extend to
    include the next day which is not a Saturday,


                                          12

<PAGE>

    Sunday, or legal holiday.  Any performance or payment which must be
    taken or made under this Agreement must be taken or made prior to 5:00 p.m.
    (Denver, Colorado time) of the last day of the applicable period provided
    hereunder for such action, unless another time is expressly specified.  All
    references to time shall be Denver, Colorado time.  If a date for
    performance or payment falls on a holiday or weekend, the time for
    performance or payment shall be extended to the next business day, and if
    performance or payment has occurred on such weekend or holiday, it shall be
    deemed to have occurred on the next business day.


33.      INVALIDITY.  The invalidity of any provision of this Agreement shall
    not affect the enforceability of any other provision of this Agreement.


34.      COUNTERPARTS.  This Agreement may be executed in any number of
    counterparts, each of which shall be deemed to be an original and all of
    which together shall constitute one and the same agreement.  If any person
    named as one of the Owners does not execute this Agreement, it nevertheless
    shall be binding upon those persons executing it.


35.      ADDITIONAL DOCUMENTS.  Owners will provide St. Mary with such
    additional documents as may be necessary to carry out the purposes of this
    Agreement.  If conditions change by reason of conveyances, assignments, or
    other matters relating to the title or description of the Property, Owners
    and St. Mary shall execute amendments of this Agreement and the Short Form
    of Agreement, and any other documents which may be necessary to reflect
    such changed conditions.


         IN WITNESS WHEREOF, the parties have executed this Agreement as of the
    date first above written.

Schedule "D" to the
Acquisition Agreement
dated for reference
November 16, 1994

May 20, 1994


Mr. Greg Hahn, VP, Minerals Exploration
St. Mary Minerals, Inc.
1776 Lincoln Street, Suite 110
Denver, CO 80203-5400

Dear Greg:

As per our recent phone call, I am herein describing terms of an Agreement,
which if affirmed by your signature, will result in our passing onto you and
your company information on an interesting "copper-oxide" prospect (prospect),
located on claimed land in New Mexico.  

The prospect was encountered during a comprehensive review of leachable 
copper reserves in the Southwestern U.S.  The prospect was explored during 
the porphyry copper era by a couple of majors, however, was not in itself big 
enough for their further interest.  We estimate that there may be upward to 
20-25 million tons of low-grade exotic copper with a possible core area of 
0.5% or better.  According to a call made to the owner last year, the 
prospect was open for option negotiations.  

Agreement to the following terms would make this prospect and our in-house 
date available to you.

l.  St. Mary Minerals, Inc. (St. Mary) would have 60 days from date of
disclosure of prospect data to accept or reject the prospect.  If rejected, St.
Mary shall submit in writing this rejection and agrees that it and any of its
officers, employees, agents, representatives or consultants for a period of
three (3) years from the date of rejection letter, shall not acquire or attempt
to acquire any interest in the prospect or any property within a mile limit
outside the boundaries of the prospect (Area to be defined on map with data). 
Furthermore, St. Mary shall keep all data on the prospect strictly confidential
for the 3-year period.

2.  If the prospect is accepted, St Mary agrees to pay Applied Geologic Studies,
Inc. (AGS) a discovery bonus amounting to $100,000.  The bonus shall be paid as
follows:

    a.  $5,000 at time of land acquisition in prospect area, or in any area
within a mile limit outside the prospect's boundaries.


<PAGE>

    b.  Five percent (5%) of total direct exploration expenditures made for
benefit of the prospect, exclusive of land costs. Expenditures would include
geologic work, geochemistry, geophysics, assay, drilling and costs related to
mine feasibility studies or mine development.  These payments would be made
annually.

    c.  Any balance (not to exceed $100,000), shall be paid at time of
decision to put the prospect into mine production.

3.  In the event that St. Mary conveys its interest in the prospect to another
party, it will require such party to expressly assume in writing St. Mary's
obligation to make the above payments; whereupon, St. Mary's further obligations
under this Agreement shall cease.  If St. Mary surrenders its interest in the
prospect, or if St. Mary's rights in the property expire or terminate in any
other way, it's obligations to make further payments under this Agreement shall
immediately cease.

If you are in agreement with the terms set forth above, please indicate by
executing both copies of the Agreement and returning one signed copy to me.

Sincerely,

/s/ William A. Rehrig

                             NET SMELTER RETURNS ROYALTY



1.       In this Agreement, the term "NET SMELTER RETURNS" shall mean the gross
revenue from the sale by the Payor of all ore, concentrate and metal produced
from the Property, after deduction of the following:

    (a)  all smelting and refining costs (excluding the cost of SX-EW
         processing), treatment charges and penalties including but not limited
         to metal losses, penalties for impurities and charges for refining,
         selling and handling by the smelter, refinery or other purchaser;

    (b)  costs of marketing, handling, transporting and insuring such ore,
         concentrate or metal from the Property or from a concentrator, whether
         situated on or off the Property, to a smelter, refinery or other place
         of treatment or to the purchaser thereof.

2.       Payments of Net Smelter Returns shall be made within 30 days after 
the end of each fiscal quarter in which Net Smelter Returns, as determined on 
the basis of final adjusted invoices, are received by the Payor.  All such 
payments shall be made in U.S. dollars.

3.       For the purposes of determining Net Smelter Returns, all receipts and
disbursements in currency other that U.S. dollars shall be converted into U.S.
currency on the day of receipt or disbursement, as the case may be.

4.       Each payment of Net Smelter Returns shall be accompanied by a
statement indicating the calculation of Net Smelter Returns paid.  The Payee
shall be entitled to audit, during normal business hours, such books and records
as are necessary to determine the correctness of the payments, provided however,
that such audit shall be made only on an annual basis and within 12 months of
the end of the fiscal period in respect of which such audit is made.

5.       Payment of Net Smelter Returns shall be made to the Payee at such
place or places in the United States as they shall advise the Payor from time to
time.

6.       The determination of the Net Smelter Returns hereunder is based on the
premise that production will be developed solely on the Property.  If other
properties are incorporated with the Property in a single mining project and
ores pertaining to each cannot be readily

segregated on a practical or equitable basis, the Payor shall have the right 
to commingle with ore from the Property ore produced from other properties 
owned or controlled by the Payor provided that the Payor will adopt and 
employ generally accepted practices and procedures for weighing, sampling and 
assaying in order to determine the amount of metals or concentrate derived 
from the Property.  The Payee, or the representative of the Payee authorized 
in writing, will be permitted to examine at all reasonable times the Payor's 
records pertaining to commingling of ores.

7.       If metal, concentrates or ore shipped from the Property are lost or
destroyed under circumstances in which the Payor receives payment under an
insurance policy, such payments will be deemed Net Smelter Returns.

8.       The Payor shall not sell, assign, transfer or in any other manner deal
with the Property or any interest therein without the purchaser, transferee or
assignee acquiring the Property or such interest therein first agreeing with the
Payor in writing to be bound by the terms of this agreement.  The Payor's
covenant to pay a 1.5% Net Smelter Return Royalty to the Payee hereunder shall
be a covenant running with the Property.

9.       No error in accounting or in interpretation of this Agreement shall be
the basis for a claim of breach of fiduciary duty, or the like, or give rise to
a claim for exemplary or punitive damages or for termination or rescission of
the Agreement or the estate and rights acquired and held by the Payor under the
terms of the Agreement.

                             NET SMELTER RETURNS ROYALTY

     1.   The term "Net Smelter Returns" means the gross revenue from the sale
by Assignee, its successors and assigns (hereinafter, "Payor") , of all ore,
concentrate, and metal produced from the property, after deduction of the
following:

          (a) all smelting and refining costs (excluding the cost of SX-EW
     processing), treatment charges and penalties including but not limited to
     metal losses, penalties for impurities and charges for refining, selling,
     and handling by the smelter, refinery, or other purchaser, and

          (b) costs of marketing, handling, transporting, and insuring such
     ore, concentrate, or metal from the Property or from a concentrator,
     whether situated on or off the Property, to a smelter, refinery, or other
     place of treatment or to the purchaser thereof.


     2.   Payments of Net Smelter Returns shall be made within thirty (30) days
after the end of each fiscal quarter in which Net Smelter Returns, as
determined on the basis of final adjusted invoices, are received by Payor. All
such payments shall be made in U.S. dollars.

     3.   For the purposes of determining Net Smelter Returns, all receipts and
disbursements in currency other than U.S. dollars shall be converted into U.S.
currency on the day of receipt or disbursement, as the case may be.

     4.   Each payment of Net Smelter Returns shall be accompanied by a
statement indicating the calculation of Net Smelter Returns paid. The payee
shall be entitled to audit, during normal business hours, such books and
records as are necessary to determine the correctness of the payments, provided
however, that such audit shall be made only on an annual basis and within twelve
(12) months of the end of the fiscal period in respect of which such audit is
made.

     5.   Payment of Net Smelter Returns shall be made to the payee at such
place or places in the United States as payee shall advise Payor from time to
time.

     6.   The determination of the Net Smelter Returns hereunder is based on the
premise that production will be developed solely on the Property. If other
properties are incorporated with the Property in a single mining project and
ores pertaining to each cannot be readily segregated on a practical or
equitable basis, the Payor shall have the right to commingle with ore from the


                                         C-1

<PAGE>

Property ore produced from other properties owned or controlled by the Payor
provided that the Payor will adopt and employ generally accepted practices and
procedures for weighing, sampling, and assaying in order to determine the amount
of metals or concentrate derived from the Property. The payee, or the
representative of the payee authorized in writing, will be permitted to
examine at all reasonable times the Payor's records pertaining to commingling
of ores.

     7.   If metal, concentrates, or ore shipped from the Property are lost or
destroyed under circumstances in which Payor receives payment under an insurance
policy, such payments will be deemed Net Smelter Returns.

     8.   The Payor shall not sell, assign, transfer, or in any other manner 
deal with the Property or any interest therein without the purchaser, 
transferee, or assignee acquiring the Property or such interest therein first 
agreeing with the Payor in writing to be bound by the terms hereof. The 
Payor's covenant to pay a One and One-Half Percent (1 1/2%) Net Smelter 
Return Royalty hereunder shall be a covenant running with the Property.

     9.   No error in accounting or in interpretation hereof shall be the basis
for a claim of breach of fiduciary duty, or the like, or give rise to a
claim for exemplary or punitive damages or for termination or rescission
hereof or the estate and rights acquired and held by the Payor under the terms
hereof.

Dear Greg:



As per our recent phone call, I am herein describing terms of an Agreement, 
which if affirmed by your signature, will result in our passing onto you and 
your company information on an interesting "copper-oxide" prospect 
(prospect), located on claimed land in New Mexico.

The prospect was encountered during a comprehensive review of leachable 
copper reserves in the Southwestern U.S. The prospect was explored (luring 
the porphyry copper era by a couple of majors, however, was not in itself big 
enough for their further interest. We estimate that there may be upward to 
20-25 million tons of low-grade exotic copper with a possible core area of 
0.5% or better. According to a call made to the owner last year, the prospect 
was open for option negotiations.

Agreement to the following terms would make this prospect and our in-house 
data available to you.

1.  St. Mary Minerals, Inc. (St. Mary) would have 60 days from date of 
disclosure of prospect data to accept or reject the prospect. If rejected, 
St. Mary shall submit in writing this rejection and agrees that it and any of 
its officers, employees, agents, representatives or consultants for a period 
of three (3) years from the date of rejection letter, shall not acquire or 
attempt to acquire any interest in the prospect or any property within a mile 
limit outside the boundaries of the prospect (Area to be defined on map with 
data). Furthermore, St. Mary shall keep all data on the prospect strictly 
confidential for the 3-year period.

2.  If the prospect is accepted, St. Mary agrees to pay Applied Geologic 
Studies, Inc (AGS) a discovery bonus amounting to $100,000. The bonus shall 
be paid as follows:

    a.  $5,000 at time of land acquisition in prospect area, or in any area 
within a mile limit outside the prospect's boundaries.

<PAGE>



    b.  Five percent (5%) of total direct exploration expenditures made for 
benefit of the prospect, exclusive of land costs. Expenditures would include 
geologic work, geochemistry, geophysics, assay, drilling and costs related to 
mine feasibility studies or mine development. These payments would be made 
annually.

    c.  Any balance (not to exceed $100,000), shall be paid at time of 
decision to put the prospect into mine production.

3.  In the event that St. Mary conveys its interest in the prospect to 
another party, it will require such party to expressly assume in writing St. 
Mary's obligation to make the above payments; whereupon, St. Mary's further 
obligations under this Agreement shall cease. If St. Mary surrenders its 
interest in the prospect, or if St. Mary's rights in the property expire or 
terminates in any other way, it's obligations to make further payments under 
this Agreement shall immediately cease.

If you are in agreement with the terms set forth above,
please indicate by executing both copies of the Agreement and
returning one signed copy to me.



Sincerely,


/s/ William A. Rehrig

Dear Bob:


     This letter confirms your engagement as Vice President and General 
Manager of Summo USA Corporation, a wholly-owned subsidiary of Summo Minerals 
Corporation.

     Your annual salary will be $ 100,000.00 and we will provide a standard 
benefits package. We anticipate introducing a cash bonus scheme which you 
will both help design and participate in once the scheme is adopted. You will 
receive options to purchase 100,000 shares of Summo Minerals Corporation. The 
options will have a 5 year term and be priced in accordance with the 
requirements of the Vancouver Stock Exchange where Summo Minerals Corporation 
is currently listed.

     Your engagement will commence on April 24, 1995. We recognize that the 
development of the Lisbon Valley Project is critical to the ongoing success 
of the Corporation.  We have agreed that should this project not proceed 
and your services no longer be required as a consequence, we will pay you one 
year's salary as a severance in these circumstances.

                                                  Very truly yours,

                             EMPLOYMENT AGREEMENT

     This Agreement is entered into this 31st day of December, 1995 between 
Summo Minerals Corporation ("Summo"), a British Columbia corporation, and 
Gregory A. Hahn ("Hahn").  This Agreement shall become effective upon the 
earlier of the employment termination of Hahn by St. Mary Minerals Inc. or 
the date of this Agreement (the "Effective Date").

     1.   EMPLOYMENT.  On the terms and conditions set forth herein, Summo 
hereby agrees to employ Hahn as President and Chief Executive Officer of 
Summo Minerals Corporation and Summo USA Corporation, and Hahn hereby agrees 
to be so employed and located in Denver, Colorado, for a minimum of one year 
from the Effective Date of this Agreement.  Hahn shall utilize his full-time 
good faith efforts to perform such duties and discharge such responsibilities 
as are customarily undertaken by such an officer of a corporation, together 
with such other appropriate duties as may be assigned to him by the Board of 
Directors of Summo.

     2.   COMPENSATION.  Summo shall compensate Hahn for his services 
hereunder at an initial rate of $120,000 per annum payable in semi-monthly 
installments.  Such compensation shall be subject to review and increase, as 
approved by the Board of Directors of Summo, in July of each year beginning 
with July, 1996.  Hahn shall participate in the fringe benefits and benefit 
plans of Summo in the same manner and to the same comparable extent as other 
senior executives of Summo, including three weeks of vacation, retirement 
benefits, life insurance, disability benefits and insurance and health and 
hospitalization benefits and insurance.  Hahn shall also be entitled to 
additional bonus or incentive compensation, as determined by the Board of 
Directors of Summo, pursuant to any plans or programs established therefore, 
to an extent comparable with other senior executives of Summo and dependent 
upon the nature of the accomplishment of his employment duties and 
responsibilities including those described in paragraph 1 above.

     3.   TERM.  

          (1)  The term of employment of Hahn by Summo shall commence as of 
the above-mentioned Effective Date.  This Agreement shall continue in effect 
for at least one year and then until terminated by Hahn or Summo upon not 
less than thirty days prior written notice to the other.  Upon any 
termination of this Agreement by Summo for any reason other than the 
occurrence of an event described in subparagraph (2) below, Summo shall

                                 Schedule "A"
- --------------------------------------------------------------------------------

                         SUMMO MINERALS CORPORATION
                    EMPLOYEE INCENTIVE STOCK OPTION PLAN

1.  PURPOSE

    The purpose of the Employee Incentive Stock Option Plan (the "Plan") is 
to promote the profitability and growth of SUMMO MINERALS CORPORATION 
("Summo") by facilitating the efforts of Summo and its subsidiaries to obtain 
and retain key individuals. The Plan provides an incentive for and encourages 
ownership of Summo's shares by its key individual so that they may increase 
their stake in Summo and benefit from increases in the value of Summo's 
shares.

2.  ADMINISTRATION

    The Plan will be administered by a committee (the "Committee") of Summo's 
Board of Directors (the "Board"), which will consist of two or more members. 
All members of the Committee shall be non-employee directors who a 
"Disinterested Persons" with regard to Plan administration, within the 
meaning of Rule 16b-3 as promulgated and amended from time to time by the 
United States Securities and Exchange Commission.

    The Committee will be authorized, subject to the provisions of the Plan, 
to adopt such rules and regulations which it deems consistent with the Plan's 
provisions and, in its sole discretion, to designate options ("Options") to 
purchase shares of Summo pursuant to the Plan. The Committee may authorize 
one or more individuals of Summo to execute, deliver and receive documents on 
behalf of the Committee.

3.  ELIGIBILITY

    All directors and officers and employees of Summo and its subsidiaries 
will be eligible to receive Options. The term "subsidiaries" for the purpose 
of the Plan will include Summo U.S.A. Corporation, which definition may be 
varied by the Committee to conform with the changing interests of Summo.

    Nothing in the Plan or in any option shall confer any right on any 
individual to continue in the employ of or association with Summo or its 
subsidiaries or will interfere in any way with the right of Summo or 
subsidiaries to terminate at any time the employment of a person who is an 
optionee ("Optionee") under an Option.

4.  SHARES SUBJECT TO OPTION

    The shares to be optioned under the Plan will be authorized but unissued 
Common Shares without par value ("Shares") of Summo.

     At no time will more than 2,000,000 Shares be under option either 
pursuant to the Plan or pursuant to other incentive stock options issued by 
Summo. The number of Shares under option at any specific time to any one 
Optionee shall not exceed 5% of the issued and outstanding common share 
capital of Summo, subject to adjustment under Section 12 below.

    Shares subject to and not delivered under an Option which expires or 
terminates shall again be available for option under the Plan. The maximum 
number of Shares which may be issued pursuant to

<PAGE>

                                       2

the Plan shall not however exceed 2,000,000 Shares.

5.  GRANTING OF OPTIONS

    The Committee may from time to time at its discretion, subject to the 
provisions of the Plan, determine those eligible individuals to whom Options 
will be granted, the number of Shares subject to such Options, the dates on 
which such Options are to be granted and the expiration of such Options.

    The Committee may, at its discretion, with respect to any Option, impose 
additional terms and conditions which are more restrictive on the optionee 
than those provided for in the Plan.

    Each Option will be evidenced by a written agreement between, and 
executed by, Summo and the individual containing such terms and conditions 
established by the Committee with respect to such Option and will be 
consistent with the provisions of the Plan.

    Options shall be granted to directors only according to the following 
formula:

      (i)  Each director who was a member of the Board of Directors prior to 
           January 1, 1996, shall upon adoption of this Plan be issued 
           Options for that number of Shares necessary to bring the aggregate 
           number of Shares underlying incentive options issued to such 
           director to 150,000 Shares. The exercise price of such Options 
           shall be determined as provided in Section 6 hereof.

     (ii)  Each director who becomes a member of the Board of Directors after 
           January 1, 1996, shall be granted Options for 50,000 Shares upon 
           his or her election or appointment to the Board. The exercise 
           price shall be determined as provided in Section 6 hereof.

    (iii)  Upon the expiration date of any Options issued to a director 
           (regardless of whether such Options were exercised on or prior to 
           the expiration date), such director shall be issued Options for an 
           additional 50,000 Shares. The exercise price shall be determined 
           as provided in Section 6 hereof. The provisions of this paragraph 
           (iii) shall also apply upon the expiration date of any other 
           incentive stock options issued to a director if at the time of 
           such expiration date, the director holds incentive options, 
           including Options, for fewer than an aggregate of 50,000 Shares 
           underlying such options, in which case the director shall be 
           issued that number of Options necessary to bring the aggregate 
           number of Shares underlying incentive options issued to such 
           director at such time to 50,000 Shares. The calculation of 
           incentive options held by any director shall not include any 
           warrants to purchase Summo shares held by a director provided such 
           warrants were issued by Summo in connection with securities 
           offered by Summo.

     (iv)  The foregoing formulas shall not be amended more than once every 
           six months other than to comport with changes in the Internal 
           Revenue Code, the Employee Retirement Income Security Act, or the 
           rules thereunder.

      (v)  Additional options may be granted to directors at the discretion 
           of the Committee,

<PAGE>

                                       3

           provided that no director may receive additional options while 
           serving on the Committee if the receipt of such options would 
           cause him to cease to be a Disinterested Person.

6.  OPTION PRICE

    The price per Share at which Shares may be purchased upon the exercise of 
an Option (the "Option Price") will not be lower that the "market price" of 
the Shares on The Toronto Stock Exchange (the "TSE") at the time of grant. In 
the context of the Plan, "market price" means the closing price of Summo's 
shares on the TSE at the close of trading which immediately preceded the time 
that the option was granted. If the shares of Summo do not trade on such day, 
the "market price" shall be the average of the bid and ask prices on the 
previous trading day.

7.  TERM OF OPTION

    The maximum term of any Option will be 10 years.

    The Option Price will be paid in full at the time of exercise of the 
Option and no Shares will be delivered until full payment is made.

    An Optionee will not be deemed the holder of the Shares subject to his 
Option until the Shares are delivered to him.

8.  TRANSFERABILITY OF OPTIONS

    An Option may not be assigned. During the lifetime of an Optionee, the 
Option may be exercised only by the Optionee.

9.  TERMINATION OF EMPLOYMENT

Upon termination of employment for any reason except death or retirement or 
failure of re-election as a director or failure to be re-appointed an 
officer of Summo, an Optionee may, at any time within 30 days after the date 
of termination but not later than the date of expiration of the Option, 
exercise the Option to the extent the Optionee was entitled to do so on the 
date of termination. Any option or portions of Options of terminated 
individuals not so exercised will terminate and again be available for future 
Options under the Plan. A change of employment will not be considered a 
termination so long as the Optionee continues to be employed by Summo or its 
subsidiaries.

10. DEATH

    Notwithstanding any other provision of this Plan other than the maximum 
of 10 years provided for in Section 7, if any Optionee shall die holding an 
Option which has not been fully exercised, his personal representative, heirs 
or legatees may, at any time within 60 days of grant of probate of the will 
or letters of administration of the estate of the decedent or within one year 
after the date of such death, whichever is the lesser time, exercise the 
Option with respect to the unexercised balance of the Shares subject to the 
Option.


<PAGE>

                                       4

11. RETIREMENT

    Notwithstanding any other provision of this Plan, if any Optionee shall 
retire or terminate his employment with the consent of the Board under 
circumstances equating retirement, while holding an Option which has not been 
fully exercised, such Optionee may exercise the Option at any time during the 
unexpired term of the Option.

12. CHANGE IN SHARES

    In the event the authorized common share capital of Summo as presently 
constituted is consolidated into a lesser number of Shares or subdivided into 
a greater number of Shares, the number of Shares for which Options are 
outstanding will be decreased or increased proportionately as the case may be 
and the Option Price will be adjusted accordingly and the Optionee will have 
the benefit of any stock dividend declared during the period within which the 
said Optionee held his Option. Should Summo amalgamate or merge with any 
other Company or companies (the right to do so being expressly reserved) 
whether by way of arrangement, sale of assets and undertakings or otherwise, 
then and in each such case the number of shares of the resulting corporation 
to which an Option relates will be determined as if the Option has been fully 
exercised prior to the effective date of the amalgamation or merger and the 
Option Price will be correspondingly increased or decreased, as applicable.

13. CANCELLATION AND RE-GRANTING OF OPTIONS

    The Committee may, with the consent of the Optionee, cancel any existing 
Option, and re-grant the Option at an Option Price determined in the same 
manner as provided in Section 6 hereof, subject to the prior approval of the 
TSE.

14. AMENDMENT OR DISCONTINUANCE

    The Board may alter, suspend or discontinue the Plan, but may not, 
without the approval of the shareholders of Summo and the TSE, may any 
alteration which would (a) increase the aggregate number of Shares subject to 
Option under the Plan except as provided in Section 12 or (b) decrease the 
Option Price except as provided in Section 12. Notwithstanding the foregoing, 
the terms of an existing Option may not be altered, suspended or discontinued 
without the consent in writing of the Optionee.

15. INTERPRETATION

    The Plan will be construed according to the laws of the Province of 
British Columbia,

16. LIABILITY

    No member of the Committee or any director, officer or employee of Summo 
will be personally liable for any act taken or omitted in good faith in 
connection with the Plan.

securities of the Issuer;

     AND WHEREAS in furtherance of complying with the requirements of the 
Exchange, the security holders are desirous of depositing in escrow certain 
securities of the Issuer owned or to be received by them;

     AND WHEREAS the Trustee has agreed to undertake and perform its duties 
according to the terms and conditions hereof;

     NOW THEREFORE this Agreement witnesseth that in consideration of the 
aforesaid agreements, and of the sum of one dollar ($1.00) now paid by the 
parties hereto, each to the other (receipt of which sum the parties do hereby 
respectively acknowledge each to the other) the Security Holders jointly and 
severally covenant and agree with the Issuer and with the Trustee and the 
Issuer and the Trustee covenant and agree each with the other and with the 
Security Holders jointly and severally as follows:

1.   Each of the Security Holders hereby places and deposits in escrow those 
of its securities of the Issuer which are represented by the certificates 
described or referred to in Schedule "A" hereto with the Trustee and, 
inasmuch as he is legally able to do so, in respect of existing restrictions 
on the delivery of such certificates (such as R.R.S.P. restrictions) hereby 
undertakes and agrees forthwith to deliver those certificates (including any 
replacement securities or certificates if and when such are issued or 
allotted) to the Trustee for deposit in escrow.

2.   The parties hereby agree that the securities and the beneficial 
ownership of or any interest in them and the certificates representing them 
(including any replacement certificates) shall not be sold, assigned, 
hypothecated, alienated, released from escrow, transferred within escrow, or 
otherwise in any manner dealt with, without the express consent, order or 
direction in writing of the Exchange being first had and obtained or except 
as may be required by reason of the death or bankruptcy of any Security Holder,
in which cases the Trustee shall hold the said certificates subject to this 
agreement, for whatever person, firm or corporation shall be legally entitled 
to be or become the registered owner thereof. It is understood that the 
Exchange has consented to a release from escrow of the securities on a PRO 
RATA basis as follows:

     (a)  one-third on the first anniversary of the date of listing of the 
          Issuer's common shares on the Exchange;

     (b)  an additional one-third on the second anniversary of the date of 
          listing of the Issuer's common shares on the Exchange; and

     (c)  the remaining one-third on the third anniversary of the date of 
          listing of the Issuer's common shares on the Exchange.

<PAGE>
                                       3 

3.   The Security Holders hereby direct the Trustee to retain their 
respective securities and the certificates (including any replacement 
securities or certificates) representing the same and not to do or cause 
anything to be done to release the same from escrow or to allow any transfer, 
hypothecation or alienation thereof except with and as directed by the 
written consent, order or direction of the Exchange. The Trustee hereby 
accepts the responsibilities placed on it hereby and agrees to perform the 
same in accordance with the terms hereof and the written consents, orders or 
directions of the Exchange.

4.   If during the period in which any of the said securities are retained in 
escrow pursuant hereto, any dividend is received by the Trustee in respect of 
the escrowed securities, any such dividend shall be forthwith paid or 
transferred to the respective Security Holders entitled thereto.

5.   All voting rights attached to the escrowed securities shall at all times 
be exercised by the respective registered owners thereof.

agreement and agrees to take all reasonable steps to facilitate its

writing appoint another Trustee in its place and such appointment shall be 
binding on the Security Holders and the new Trustee shall assume and be bound 
by the obligations of the Trustee hereunder.

9.   The written consent, order or direction of the Exchange as to a release 
from escrow of all or part of the said securities shall terminate this 
agreement only in respect to those securities so released. For greater 
certainty, this clause does not apply to securities transferred within escrow.

10.  If the Issuer is delisted by the Exchange, thereafter any consent, order 
or direction of the Exchange herein required will, instead, require the 
consent, order or direction of the Ontario Securities Commission.

11.  This agreement may be executed in several parts in the same form and 
such parts as so executed shall together form one original agreement, and 
such parts if more than one shall be read together and construed as if all 
the signing parties hereto had executed one copy of this agreement.

    greater number of shares, the number of shares in respect of which the 
    Option remains unexercised shall be decreased or increased 
    proportionately as the case may be, and the then prevailing purchase 
    price to be paid by the Optionee for each such share shall be 
    correspondingly decreased or increased as applicable. In the event the 
    Company shall determine to amalgamate or merge with any other company or 
    companies (and the right to do so is hereby expressly reserved) whether 
    by way of statutory amalgamation, sale of its assets and undertaking, or 
    otherwise howsoever, then and in each such event the number of shares in 
    the corporation resulting from such amalgamation or merger in respect of 
    which the Option remains unexercised shall be such number of shares in 
    that corporation as would have been acquired by the Optionee pursuant to 
    the amalgamation or merger had the Option been fully exercised immediately
    prior to the date of such amalgamation or merger and the then prevailing
    purchase price of the shares to be paid by the Optionee shall be 
    correspondingly decreased or increased as applicable.
    
TERMINATION OF OPTION

    30th day following the date upon which the Optionee ceases to be an       
    Insider of the Company; provided, however, that if such cessation is due  
    to the death of the Optionee, the personal representative of the Optionee 
    shall have the right to exercise any unexercised part of the Option for a 
    period of one year following the date of death of the Optionee.
    
AMENDMENT OF MATERIAL TERMS

13. Any amendment to the Option is subject to approval by ordinary resolution
    of the members of the Company entitled to vote at a general meeting of 
    the Company.

[LETTERHEAD ILLEGIBLE]

                                 January 29, 1996


James D. Frank
7773 S. Oneida Court
Englewood, CO 80112

FAX: (303) 290-9165

Dear Jim:

This letter confirms our offer to you for employment as Vice President - 
Finance and Chief Financial Officer for Summo Minerals Corporation and Summo 
USA Corporation, a wholly-owned subsidiary, beginning February 1, 1996.

Your initial annual salary will be US$110,000.00.  Summo offers a standard 
health benefits package and a 401(k) plan for its employees, which you would 
be eligible to participate in.  You will be awarded a stock option by the 
Board of Directors to purchase 100,000 shares of Summo Minerals Corporation 
common stock.  The option price will be set by the market price at the date 
the option is issued.  The option will have a 5-year term.  You will be 
vested in 25% of the option immediately, with additional vesting accruing at 
25% increments annually; you will be fully vested after 3 years.

The Compensation Committee of the Board will be establishing a bonus plan for 
Executive Management to reward executives for outstanding performance in 
accomplishing key milestones which bear significantly on the Corporation's 
future.  Milestones for 1996 include obtaining the requisite operating 
permits for Lisbon Valley and securing project financing.  Anticipated 
milestones for 1997 include completion of construction on time and within 
budget and successful start-up and operation at Lisbon Valley.  You can 
expect to participate in this bonus plan as one of the key executives in the 
Corporation.  The bonus package will likely take the form of additional stock 
options, and/or cash.

We recognize that the permitting and financing of the Lisbon Valley project 
is critical to the ongoing success of the Corporation.  We have agreed that 
should this project not proceed and your services are no longer required as a 
consequence, or in the event of a change of control of the company whereby 
you are asked to resign or to perform in a reduced capacity to the position 
being offered, Summo will continue your salary and benefits for one year as a 
severance.

<PAGE>

If these terms are acceptable to you, please accept by signing below.  I trust 
you find the opportunity to join Summo and contribute to building a solid 
mining company exciting.  I believe together we would constitute a solid core 
management team that can fulfill the vision of becoming a multiple-mine 
operator within the next 5-10 years, with a targeted mine output of 100 
million pounds of cathode copper by the end of this period.  I look forward 
to working with you and having your input on the financial and business 
issues the Company will address as it grows.


                                       Sincerely,

                                       /s/ GREGORY A. HAHN

         SECTION 3: DELIVERY OF AND CHARGES FOR FIRM POWER AND ENERGY

     3.1 SCOPE OF DELIVERIES: The Contract Demand for deliveries under this 
Agreement is 7,500 kW. PacifiCorp shall deliver such amounts of Firm Power 
and Energy SUMMO requires to meet its load requirements up to, but not in 
excess of, such Contract Demand; PROVIDED, that if the Measured Demand 
exceeds the Contract Demand as a result of SUMMO's operations, the Measured 
Demand shall establish a new Contract Demand if PacifiCorp has capacity 
available adequate to supply such Demand on a firm basis. PacifiCorp shall 
notify SUMMO within sixty (60) days of the billing covering the period in 
which Measured Demand exceeded the Contract Demand whether such capacity is 
available. In such event, the new Contract Demand shall continue in effect 
until either (1) the new Demand is in turn exceeded by a Contract Demand, or 
(2) the eleventh billing

                                       2
<PAGE>

month following the billing month in which such Demand was established;
PROVIDED, in the latter event the Contract Demand shall then become the maximum
actual Measured Demand established in any of the preceding eleven (11) billing
months.

     3.2 REQUEST FOR ADDITIONAL CONTRACT DEMAND: Upon PacifiCorp's receipt of 
SUMMO's written request for additional power and energy, PacifiCorp shall 
attempt to supply such additional power and energy under terms and conditions 
acceptable to both parties. Within 15 days of the request PacifiCorp shall 
advise SUMMO in writing whether the additional power and energy is or can be

the date of this Agreement SUMMO expects to obtain all necessary permits and 
financing for its copper mining facilities in Lisbon Valley, Utah. Summo 
shall notify PacifiCorp when it obtains such permits and financing. If SUMMO 
provides such notice after December 24, 1996, PacifiCorp may recalculate the 
cost of the line extension and adjust the line extension payment and 
guaranteed minimum payments in a manner to compensate PacifiCorp fully for 
any decreased value of the dollar from the date of this Agreement to the date 
PacifiCorp receives such notice. Until it gives notice to PacifiCorp, 
SUMMO shall owe no financial obligation to PacifiCorp except the payment 
of $35,000 required upon execution of this Agreement pursuant to section 4.4. 
SUMMO shall make the first payment required under section 4.4 when it 
notifies PacifiCorp that it has obtained the necessary permits and financing. 
PacifiCorp shall complete construction of the facilities necessary to provide 
service to SUMMO in accordance with the terms of this agreement within eight 
(8) months of its receipt of such notice.

     3.4 POINT OF DELIVERY: The Point of Delivery for all Firm Power and 
Energy delivered to SUMMO shall be at the terminus of PacifiCorp's 69 kV 
power line at SUMMO's copper mine.

     3.5 DELIVERY VOLTAGE: PacifiCorp shall deliver Firm Power and Energy at 
the Point of Delivery in the form of alternating current at a nominal 
frequency of 60 Hertz, and at a nominal voltage of 69,000 volts.

     3.6 REACTIVE REQUIREMENTS:

          3.6.1 SUMMO'S OBLIGATIONS: SUMMO shall control and limit the flow 
     of reactive power between PacifiCorp's and SUMMO's system so as to 
     maintain a Power Factor of between ninety five percent (95%) lagging and 
     ninety percent (90%) leading at all times. If SUMMO's Power Factor 
     adversely affects operation of PacifiCorp's facilities or adversely 
     affects PacifiCorp's other customers, SUMMO shall install at SUMMO's 
     expense switched capacitors, synchronous condensers, or such other 
     devices and

                                       3
<PAGE>

     equipment as PacifiCorp may reasonably require to eliminate that portion
     of unscheduled reactive power flow which causes the Power Factor to 
     exceed the limits established herein. Should SUMMO fail to take
     corrective action requested by PacifiCorp within six (6) months after 
     written notice from PacifiCorp, PacifiCorp may perform such services or 
     supply and install such equipment as it deems necessary to provide 
     corrective action, whereupon SUMMO shall compensate PacifiCorp for all 
     sums expended and all services contracted or performed, including 
     PacifiCorp's standard overhead costs, plus ten percent (10%) of all 
     expenditures. SUMMO shall pay such sums within thirty (30) days after 
     PacifiCorp has mailed to SUMMO an itemized statement of its charges 
     therefor.

           3.6.2 ADJUSTMENT TO BILLING DEMAND: In the event SUMMO's Power 
     Factor drops below either 95% lagging or 90% leading, PacifiCorp's 
     Billing Demands shall be increased as specified for Power Factor that 
     drops below 90% lagging in Electric Service Schedule 9.

           3.6.3 HARMONICS: SUMMO shall operate its facilities on harmonic
     distortion within the guideline of the Agreement.

                     3.6.3. 1 The total harmonic voltage distortion (THD) 
          shall be less than five percent (5%), and the maximum individual 
          frequency voltage harmonic shall be less than three percent (3%) of 
          the fundamental. The voltage notch depth shall be less than twenty 
          percent (20%) and the notch area shall be less than 22,800 
          microseconds-volts.

                3.6.3.2 The total demand distortion (TDD) or harmonic current 
          distortion shall be less than eight percent (8%) of the maximum 
          demand load current. Individual odd current harmonics shall be less 
          than the following percentage of the fundamental (60 hertz) current.

                               3rd through 9th      7.0%
                               11th through 15th    3.5%
                               17th through 21st    2.5%
                               23rd through 35th    1.5%
                               35th and higher      0.5%

          Individual even harmonics shall be limited to twenty-five percent 
          (25%) of the odd harmonic limits specified above.

                     SECTION 4: PAYMENT FOR POWER AND ENERGY

     4.1 STATEMENTS: All billing statements shall show the amount due for 
Firm Power and Energy purchased.

     4.2 PAYMENT FOR POWER AND ENERGY: PacifiCorp shall serve SUMMO under 
Electric Service Schedule No.9. All bills shall be paid by the due date of 
the bill.

     4.3 GUARANTEED MINIMUM PAYMENT: In consideration of the special 
investment by PacifiCorp to supply service hereunder, SUMMO shall make 
minimum annual total payments for service of $281,664 in each year for a 
period of five years, beginning six months from the commencement of 
deliveries. The guaranteed minimum payments shall be in the amount of $23,472 
per month for sixty (60) consecutive months. PacifiCorp shall calculate and 
bill the guaranteed minimum at intervals of every twelve (12) months 
beginning one year from commencements of deliveries. Where the actual billed 
service is less than $281,664, PacifiCorp shall bill SUMMO for the difference 
between actual billed service and the required stated minimum. In the event 
actual use as determined by meter readings exceeds the monthly minimum 
guaranteed payment, SUMMO shall pay the higher amount.

      AVAILABILITY: At any point on the Company's interconnected system where 
there are facilities of adequate capacity.

     APPLICATION: This Schedule is for alternating current, three-phase 
electric service supplied at approximately 46,000 volts or 69,000 volts or 
greater, through a single point of delivery. Seasonal service will be 
available only under other appropriate schedules.

     MONTHLY BILL: (Computer Codes 9, 115, 116)

            CUSTOMER SERVICE CHARGE: 
                 $100.00 per service connection

            MINIMUM: The monthly customer charge plus appropriate power and 
            energy charges.

     POWER FACTOR: This rate is based on the Customer maintaining at all 
times a Power factor of 90% lagging, or higher, as determined by measurement. 
If the average Power factor is found to be less than 90% lagging the Power as 
recorded by the Company's meter will be increased by 3/4 of 1% for every 1% 
that the Power factor is less than 90%.

     CONTRACT PERIOD: One year or longer.

     CONTRACT DEED: This provision does not apply to any General Service 
Customers who contracted prior to July 29, 1982, for service except for those 
Customer's whose Electric Service Agreements already contain this 
specification. However, in the event that Customer makes any material changes 
or increases in his installation which amount to at least 25% of Customer's 
greatest historical actual demand, Company, under the provisions of Paragraph 
6, Electric Service Regulation No. 5, will require a new Contract containing 
this provision. "Contract Demand" as used herein shall mean the maximum Power 
contracted for by Customer and in excess of which the Company is under no 
obligation to supply, as set forth in the Electric Service Agreement executed 
by

                 ELECTRIC SERVICE SCHEDULE NO. 9 - CONTINUED

     and action of Customer but are not the result of Customer's usual and 
     ordinary operations, shall be excluded from determination of new 
     Contract Demands. Upon prior arrangement with Company, Customer may 
     test, repair or start-up equipment at mutually acceptable and scheduled 
     off-peak periods and any demands in excess of the Contract Demand 
     established during such test, repair or start-up shall be excluded from 
     determination of new Contract Demands.

     FORCE MAJEURE: Neither Company or Customer shall be subject to any 
liability or damages for inability to provide or receive service to the 
extent that such failure shall be due to causes beyond the control of 
either Company or Customer, including, but not limited to the following: 
(a) the operation and effect of any rules, regulations and orders 
promulgated by any Commission, municipality, or governmental agency of 
the United States, or subdivision thereof; (b) restraining order, 
injunction or similar decree of any court; (c) war; (d) flood; (e) 
earthquake; (f) act of God; (g) sabotage; or (h) strikes or boycotts. 
Should any of the foregoing occur, the minimum billing demands that 
would otherwise be applicable under this Schedule shall be waived and 
Customer will have no liability for service until such time as Customer 
is able to resume service.

     The party claiming Force Majeure under this provision shall make 
every reasonable attempt to remedy the cause thereof as diligently and 
expeditiously as possible.

     Should Customer find it necessary to shut down operations because 
of market or economic conditions for a period of at least thirty (30) 
days, the 65% minimum billing demands that would otherwise be 
applicable under this Schedule shall be waived; provided, however, that 
in this event, 65% minimum billing demands shall not be waived for more 
than two (2) billing months in any contract year.

     TERMINATION: This provision does not apply to any Customers who 
contracted prior to July 29, 1982, for service except for those 
Customers whose Electric Service Agreements contain Contract Demand 
provisions with 65% minimum demand payment obligations. Termination of 
electric service by the Customer prior to the expiration date of the 
Electric Service Agreement (or any extension thereof) will not relieve 
the Customer of his obligations under this Rate Schedule and the 
Electric Service Agreement, including all 65% minimum payment 
obligations. In the event of termination, the 65% minimum payment 
amounts as stated herein, shall remain in full force and effect for the 
remaining unexpired term of the Electric Service Agreement; provided, 
however, that Company upon written request of Customer, shall attempt to 
sell Customer's Contract Demand obligations, or any portion thereof, to 
other parties and, upon such sale, Customer shall be relieved of the 
equivalent 65% minimum Contract Demand payment obligation. Company shall 
determine the priority of Customer's request to sell any Portion of its 
Contract Demand obligations by the date upon which Company receives 
Customer's written request. A sale is deemed to have occurred on the 
date Company executes an Electric Service Agreement for service with 
another party, and Customer, in order of priority, shall be relieved of 
its equivalent 65% minimum Contract Demand payment obligation as of that 
date.

     Termination prior to the expiration date of the Electric Service 
Agreement (or any extensions thereof) shall not relieve Customer of any 
non-contract demand minimum payment obligations incurred as a result of 
Company investments in special facilities

The SELLER and BUYER agree that the following terms and conditions govern the
sale of the Product:

1.   TAXES:  All Federal, State or local taxes (except income taxes) now or
hereafter imposed in respect to this order, or any transaction involved herein
and/or the Production sale, use consumption, delivery, transportation of the
Product shall be for account of the BUYER, and if paid or required to be paid by
the SELLER, the amount thereof shall be added to and become a part of the price
payable to the BUYER hereunder.

2.   FINANCIAL RESPONSIBILITY:  If, in the reasonable opinion of SELLER, the
credit or financial responsibility of BUYER is, or becomes, impaired or
unsatisfactory, SELLER reserves the right to demand cash or satisfactory
security before making shipment.  If BUYER fails to provide cash or satisfactory
security to fully satisfy SELLER's demands, such failure shall constitute a
breach of the Agreement, and SELLER shall have the right to withhold further
shipments and/or to cancel this Agreement or any part of this Agreement at the
option of SELLER, without any liability or obligations on the SELLER.  Such
withholding of shipments and/or cancellation, however, shall not affect the
BUYER's liability for damages, including the costs associated with reshipment of
tank railcars or tank trucks due to BUYER's failure to meet its financial
responsibilities.  Additionally, SELLER reserves the right to possession of the
Product and the right to stop Product in transit.  The acceptance by SELLER of
any payment less than the full amount due shall not be a waiver of any rights of
SELLER.

3.   PAYMENT:  Payment of the price shall be made in lawful money of the United
States, as per the Payment Terms specified on the front of this document.  If
payment is not made when due, or in the manner herein provided, SELLER may at
its option, without notice, cancel this Agreement as to all or any part of the
unfilled quantity.  Sales and use taxes paid or required to be paid by the
SELLER, which are part of the price pursuant to Paragraph 1, shall be included
in the billing for the Product delivery.  All other taxes which become part of
the price pursuant to Paragraph 1, the amount of which cannot be determined on
the invoice date, will be billed when they become known and will be payable
within thirty (30) days of billing date.

4.   TITLE:  Unless otherwise specified, title to and risk of loss of any
shipment of Product shall pass from SELLER to BUYER FOB railroad tank car or
tank truck at the destination point unless BUYER supplies the equipment to
transport the Product, in which case title and risk of loss shall pass FOB
railroad tank car or tank truck at loading point.

5.   LIABILITY: SELLER assumes no responsibility for the condition of trucks,
tank cars and related equipment supplied by BUYER.  SELLER is not responsible
for, and BUYER agrees to indemnify, defend, and save harmless the SELLER against
any, and all liabilities, claims, investigations, suits, causes of action,
judgments, losses, penalties, costs or expenses (including, without limitation,
reasonable attorneys fees) (collectively, "Liabilities"), arising out of or in
consequence of, or alleged to have arisen out of or in consequence of, in whole
or in part 1) any breach or default by the BUYER of the terms or conditions of
this Agreement, 2) any and all negligent acts by the BUYER, 3) any and all civil
or criminal breaches or violations or statutes, regulations, ordinances, or
otherwise by the BUYER, 4) any and all Liabilities predicated on theories of
strict liability, whether imposed or arising under a statute, ordinance,
regulation, or at common law or otherwise by the BUYER, 5) any and all improper
acts of loading, transporting, storage, handling, or application of the Product
by the BUYER, or, 5) any subsequent resale of the Product or other disposal by
the BUYER, including, but not limited to, any and all representations or
warranties that the BUYER makes to a third party in the course of the resale or
other disposal of the Product, or 7) any and all other acts or omissions of
BUYER, whether arising under this contract or otherwise, which result in
Liabilities to the SELLER.  BUYER hereby assumes liability for, and shall
reimburse SELLER for, all damage to, and all loss or description of, any private
tank car or tank truck (including the fittings and appurtenances thereto)
occurring while said tank car or tank truck is in the possession of BUYER,
except when such damage, loss or destruction does not result from the negligence
or default of BUYER.  BUYER's reimbursement of SELLER hereunder shall be limited
to the lessor of: (a) the actual cost to SELLER of repairing, reconditioning or
replacing said tank car or tank truck, or (b) the actual depreciated cash value
of said tank car or tank truck at the time of such damage, loss or destruction.
BUYER shall report promptly to SELLER all damage to, or loss or destruction of,
any such tank car or tank truck, howsoever arising, occurring while such tank
car or tank truck is in the possession or under the control of BUYER.

6.   WARRANTY:  Attached to this Agreement is a Composite Analysis, for the
dates indicated, of the Product.  SELLER OR PRODUCER MAKE NO EXPRESS OR IMPLIED
WARRANTIES OF ANY KIND, INCLUDING WHETHER THE PRODUCT CONFORMS TO THE ATTACHED
COMPOSITE ANALYSIS.  NO WARRANTY BY SELLER OR PRODUCER (OTHER THAN WARRANTY OF
TITLE AS PROVIDED IN THE UNIFORM COMMERCIAL CODE) SHALL BE IMPLIED OR OTHERWISE
CREATED UNDER THE UNIFORM COMMERCIAL CODE INCLUDING, BUT NOT LIMITED TO,
WARRANTY OF MERCHANTABILITY OR WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE.

7.   NOTICE:  The BUYER shall give written notice of any claim for any cause
whatsoever within ten (10) days after arrival of any shipment at destination,
and failure to do so shall constitute a waiver by the BUYER of all claims with
respect to such shipment.  For any defect of quality established, SELLER's
liability shall be limited to replacing any defective acid delivered hereunder
and in no event shall SELLER incur liability for defects or damage to Products
in which acid delivered hereunder is used or for any other kind of
consequential, nominal, or incidental damages.

8.   INVOICE: SELLER shall invoice BUYER for each delivery on the basis of price
provided herein, and each such delivery shall constitute a separate and
independent sale.  SELLER's weights and analyses shall govern unless proven to
be in error.

9.   MUTUALLY AGREED PRODUCER: BUYER agrees that SELLER may meet its commitments
under this Agreement by having a mutually agreed producer deliver Product on
behalf of SELLER, so long as the agreed producer otherwise agrees to meet the
terms and conditions of this Agreement.

10.  FORCE MAJEURE: This Agreement is subject to the following conditions of
force majeure.  Any strike, lockout, difference with workmen, accident, fire,
explosion, flood, earthquake, storm, unavoidable accident, mechanical breakdown
(including shutdowns for maintenance and inventorying) mobilization, war
(whether declared or undeclared), riot, rebellion, revolution, requirement,
regulation, restriction, or other act of any government, whether legal or
otherwise, the elements, inability to secure or delay in securing fuel, or other
supplies or materials, or power, necessary for the operation of the mines and
plants where the Product sold hereunder is produced or consumed, economic
shutdown of SELLER's or BUYER's mine or plant facilities, delays or interruption
to, or destruction of mines or plants of SELLER or BUYER, or any other acts
beyond the control of the parties, whether or not of the nature or character
hereinabove specifically enumerated which delays or interferes with the
performance of this Agreement shall be considered sufficient justification for
delay in making shipments, delivery or performance hereunder, in whole or in
part, until such cause ceases to exist; and this Agreement shall be deemed
suspended as long as such cause prevents or delays its execution.  Neither party
shall be responsible for or liable to the other for damages or expenses incurred
or sustained because of any delay or failure to perform because of a condition
of force majeure.  If under any of the conditions set forth in this Paragraph,
supplies of sulfuric acid available to SELLER are insufficient to complete
delivery of orders accepted by SELLER prior to the occurrence of the condition
or to SELLER's nominated long term regular contract customers.  SELLER shall
allocate available supplies pro rata to such long term customers until such
customers' contractual requirements are met by SELLER, and then SELLER may, at
its option, allocate available supplies (having first satisfied the long term
customers' contractual requirements) in a manner it deems suitable, without
liability for any damages sustained by BUYER.  A nominated long term regular
contract customer is a minimum annual tonnage commitment of 50,000 sl or more
and five (5) years or longer in original contract duration.  BUYER shall
allocate purchased supplies pro rata to such long term suppliers until such
suppliers' contractual requirements are met by BUYER, and then BUYER may at its
option allocate purchases (having first satisfied the long term suppliers
contractual requirements) in a manner it deems suitable without liability for
damages sustained by supplier.  If deliveries are interrupted or delayed for any
condition of force majeure, the amount of Product which is not delivered at the
regular order rate during the period of any such suspension or reduction shall,
at the option of SELLER, be deducted from the full amount which otherwise would
have been delivered under this order in which event SELLER shall not be
obligated to make up such omitted deliveries either during the order period or
after termination thereof.  It is understood and agreed that SELLER shall be
under no obligation to operate its copper smelters nor will it be under any
obligation to operate its sulfuric acid plants except as, and to the extent
that, it shall have available for that purpose sulfurous cases of commercial
grade, produced in the course of operating its smelter and lack of such gases
shall be deemed a cause beyond SELLER's control and subject to the Force Majeure
provision and, notwithstanding paragraph 9 of this Agreement, SELLER is not
obligated to find another producer to meet its obligations under a condition of
force majeure.

11.  HAZARDS: BUYER acknowledges that there are hazards associated with the use
of the Product.  BUYER agrees to make its personnel concerned with the Product
aware of the hazards and assumes all responsibility for the warning of its
employees and independent contractors of all hazards to persons and property in
any way connected with Product.  BUYER also assumes all responsibility for the
risks of using Product in combination with other articles or substances and in
any manufacturing process.  The SELLER shall not be liable to the BUYER for any
consequential, nominal, or incidental damages, including lost profits, arising
out of the use, handling, storage, or any application or activity related to the
Product.  The SELLER shall not be liable to the BUYER for compensation,
reimbursement or damages on account of loss of prospective profits or
anticipated sales or on account of expenditures, investments or commitments in
connection with the business or good will of the BUYER caused by failure of
Product to conform to the specifications herein set forth.

12.  CLAIMS: The BUYER will promptly notify the SELLER in writing of any
claims, demands, suit, action, or proceeding with respect to the Product.

13.  GOVERNING LAW: This Agreement shall be deemed to be made under and shall be
governed by the laws of the Sale of Utah in all respects, including matters of
construction, validity, and performance.

                               SURFACE AGREEMENT

     This Agreement, effective as of the 10th day of June, 1996, is between Joe 
Henry Pacheco and Susie Pacheco, husband and wife: James Pacheco and Libbie

("SUMMO"), whose address is 1776 Lincoln St., Suite 900, Denver, Colorado 80203.

RECITALS

     Surface Owner represents that he is the owner of and is in possession of 
the surface estate in certain lands in Taos County, New Mexico (the 
"Property"), more particularly described in Exhibit A attached hereto and 
incorporated by reference herein.

     SUMMO is the owner of certain unpatented mining claims (the "Claims") 
located on the reserved mineral estate underlying the Property.

     NOW THEREFORE, in consideration of Ten Dollars ($10.00) in hand paid to 
Surface Owner, the receipt and sufficiency of which are hereby acknowledged, 
and further in consideration of the mutual covenant, agreements, and promises 
herein contained, the parties hereto agree as follows:

     RIGHT TO USE SURFACE:  Surface Owner grants to SUMMO the sole and 
     exclusive right to use the Property for the purpose of exploring, 
     developing, and mining the Claims.

     TERM:  The term of this Agreement shall be for twenty (20) years from the 
     date hereof and so long thereafter as SUMMO holds any interest in the 
     Claims, unless SUMMO sooner surrenders this Agreement.

     OPERATIONS:  (a)  During the term of this Agreement, SUMO shall have 
     unrestricted access to the Property, and shall have the right (i) to 
     explore, develop, and mine from the Claims by means of operations on the 
     Property, (ii) to deposit ores, water, waste, and materials from the 
     Claims or from other mining properties within a two-mile perimeter of the 
     Property, and to use any part of the Property for waste dumps and tailings 
     disposal areas, (iii) to conduct on the Property general mining,


                                       1
<PAGE>

     milling, processing, and related operations respecting the Claims and other
     mining properties, and to use any part of the Property for any purposes 
     incident to such operation, and (iv) to erect, construct, use, and maintain
     on the Property such roads, buildings, structures, machinery, equipment, 
     personal property, fixtures, and improvements as may be necessary or 
     convenient for the conduct of SUMMO's operations.

     (b)  SUMMO shall conduct all operations on the Property in a good and 
     workmanlike manner and in accordance with accepted mining practice.

     (c)  SUMMO may use any mining method, whether or not the method is in 
     general use at the time of the execution of this Agreement, including, 
     without limitation, underground mining (including methods, such as block 
     caving, which result in the disturbance or subsidence of the surface), 
     surface mining (including strip mining, open pit mining, and dredging), 
     and in situ mining (including solution mining, leaching, gasification, and 
     liquification).  Surface Owner shall be notified within ten (10) days if 
     SUMMO decides to use solution mining, leaching, gasification, and 
     liquification methods.

     (d)  SUMMO shall comply with all laws and regulations governing its 
     operations on the property.  If this Agreement is inconsistent with or 
     contrary to any law or regulation, the law or regulation shall control and 
     this Agreement shall be deemed to be modified accordingly.

     (e)  SUMMO may use existing roads, if any, on the Property, and may 
     construct and maintain at its own expense any additional roads reasonably 
     necessary or convenient for the conduct of SUMMO's operations on the 
     Claims or on other mining properties.  SUMMO will endeavor to construct 
     any such additional roads on the Property at a location agreeable to 
     Surface owner and SUMMO. All additional roads shall be constructed and 
     maintained in such manner to bear the traffic necessary to SUMMO's 
     operations.  Surface Owner may use any additional road so long as his use 
     does not interfere with SUMMO's use.  Upon notice to SUMMO given within 
     thirty (30) days after the termination of this Agreement, Surface Owner 
     may require that all or any part of any additional road be reclaimed.

     (f)  If SUMMO finds it necessary to cut any fence on the Property for the 
     purpose of passage, SUMMO shall, prior to cutting the fence, install and 
     brace heavy "corner-type" posts at each end of the opening to be made, to 
     which the fence wire shall be securely fastened in such manner as to 
     prevent sagging.  Summo shall install a gate of a quality acceptable to 
     Surface Owner in each opening.  If SUMMO desires that opening provide 
     uninterrupted ingress and egress, it may in the alternative install


                                       2
<PAGE>

     cattle guards of sufficient size and substance to bear the type of traffic 
     necessary for its operations and capable of turning all domestic livestock.

     (g)  SUMMO shall conduct no surface operations within three hundred (300) 
     feet of the main dwelling house, if any, now located on the Property 
     without first obtaining the written consent of Surface Owner.

     (h)  Neither SUMMO nor its agents, employees, contractors, or 
     subcontractors, nor their agents or employees, shall hunt or fish on the 
     Property, nor shall any of them carry onto the property firearms or other 
     equipment designed or adapted for such purposes.

     (i)  SUMMO shall advise Surface Owner prior to final mailing facility site 
     selections in order that Surface Owner may clear timber from the area 
     before construction commences.

     COMPENSATION:  SUMMO shall pay compensation to Surface Owner on the dates 
     and in the amounts as follows:

          Signing bonus:     $8,000.00, payable at signing.

<PAGE>

                                        2


       NOW THEREFORE THIS AGREEMENT WITNESSES that in consideration of the 
premises and of the covenants and agreements herein contained the parties 
hereto covenant and agree as follows:

1.     From the date hereof, and for so long as the Optionee shall be an 
employee of the Company, the Optionee shall have and be entitled to and the 
Company hereby grants to the Optionee, on the terms and conditions 
hereinafter set out, an option to purchase all or any portion of an aggregate 
of ONE HUNDRED AND TWENTY THOUSAND (120,000) fully paid and non-assessable 
common shares of the Company from the treasury on or before MARCH 25, 2001 at 
the price of ONE DOLLAR AND TEN CENTS ($1.10) per share.

2.     The right to exercise the option herein granted is based upon the 
progress of permitting, financing and completion of construction of the 
Company's principal mining property situated near Moab, Utah, and known as 
the Lisbon Valley Project (the "PROJECT"), since the Optionee is part of 
senior management of the Company and in such position is materially 
responsible for bringing the Project into commercial production as a mine.

3.     The Optionee shall have the right to purchase 30,000 shares of the 
Company subject to this agreement (the "FIRST TRANCHE") only if, on or before 
December 31, 1996, all material permits have been issued by the applicable 
federal, state, county and other regulatory bodies to allow the commencement 
of construction for the Project.

4.     Whether or not the Optionee becomes entitled to purchase the First 
Tranche, the Optionee shall have the right to purchase an additional 40,000 
shares of the Company subject to this agreement (the "SECOND TRANCHE") only 
if, on or before June 30, 1997, agreements have been entered into between the 
Company and third parties which, on completion, will provide financing for 
the completion of construction for the Project.

5.     Whether or not the Optionee becomes entitled to purchase the First 
Tranche and/or the Second Tranche, the Optionee shall have the right to 
purchase an additional 50,000 shares of the Company subject to this agreement 
(the "THIRD TRANCHE") only if, on or before the first anniversary of the 
production of cathode copper at the Project, the Company has substantially 
satisfied all of the conditions established for the commercial completion of 
the Project by the senior lending institutions providing the financing.

6.     The determination as to whether the conditions have been met for the 
purchase by the Optionee of each of the First Tranche, the Second Tranche and 
the Third Tranche shall be made by the directors of the Company, and prompt 
notice of such determination shall be given to the Optionee.

7.     Notwithstanding that none or only some of the conditions set out in 
paragraphs 3, 4 and 5 hereof have been met, the Optionee shall become 
immediately entitled to purchase any unexercised part of the 120,000 shares 
subject to this agreement in the event that the Company undergoes a "Change 
of Control" (as that term is hereinafter defined). For the purposes of this 
Agreement, a "CHANGE OF CONTROL" shall be deemed to have occurred at any time 
following the effective date of this agreement when:

       (a)   a person becomes a new control person (as that term is defined in 
             the SECURITIES ACT of British Columbia) of the Company; or

<PAGE>

                                        3


       (b)   a majority of the directors elected at any annual or special 
             general meeting of shareholders of the Company are not individuals
             nominated by the Company's then-incumbent board of directors.

8.     The right to take up shares pursuant to the option herein granted is 
exercisable by notice in writing to the Company accompanied by a certified 
cheque in favour of the Company for the full amount of the purchase price of 
the shares being then purchased. When such payment is received, the Company 
covenants and agrees to issue and deliver to the Optionee share certificates 
in the name of the Optionee for the number of shares so purchased.

9.     This is an option agreement only and does not impose upon the Optionee 
any obligation to take up and pay for any of the shares under option.

10.    Subject to paragraph 11 hereof, the option herein granted shall cease 
and become null and void following the tenth day after which the Optionee 
ceases to act as a director of the Company.

11.    The Optionee hereby acknowledges that in the event the Optionee is an 
insider of the Company, the option herein granted may not be exercised in 
full or in part until this agreement has been approved by the members at a 
general meeting of the Company.

12.    The Company hereby covenants that it will seek the approval of the 
members to the incentive stock option herein granted, together with any 
amendments thereto, at the next general meeting of the Company prior to 
exercise thereof by the Optionee, in accordance with the requirements of The 
Toronto Stock Exchange, and the Optionee warrants that he will not exercise 
all or any portion of the subject option until such approval is obtained.

13.    The Company hereby covenants and agrees to and with the Optionee that 
it will reserve in its treasury sufficient shares to permit the issuance and 
allotment of shares to the Optionee upon full exercise of the option herein 
granted.

14     If at any time during the continuance of this agreement, the parties 
hereto deem it necessary or expedient to make any alteration or addition to 
this agreement, they may do so by means of a written agreement between them 
which will be supplemental hereto and form part hereof and which may be 
subject to the approval of the securities regulatory bodies having 
jurisdiction.

15.    This agreement may be executed in several parts in the same form and 
such parts as so executed will together constitute one original agreement, 
and such parts, if more than one, will be read together as if all the signing 
parties hereto had executed one copy of this agreement.

16.    This agreement shall enure to the benefit of and be binding upon the 
parties hereto and their respective heirs, executors, administrators, and 
successors.

17.    Wherever the plural or masculine are used throughout this agreement, 
the same shall be construed as meaning singular or feminine or neuter or the 
body politic where the context of the parties thereto require.

18.    The Optionee hereby acknowledges and confirms that he has obtained 
independent legal advice with respect to this agreement and understands and 
is aware that the securities of the

<PAGE>

                                  Schedule "A"

- --------------------------------------------------------------------------------

                           SUMMO MINERALS CORPORATION
                      EMPLOYEE INCENTIVE STOCK OPTION PLAN

1.     PURPOSE

       The purpose of the Employee Incentive Stock Option Plan (the "Plan") 
is to promote the profitability and growth of SUMMO MINERALS CORPORATION 
("Summo") by facilitating the efforts of Summo and its subsidiaries to obtain 
and retain key individuals. The Plan provides an incentive for and encourages 
ownership of Summo's shares by its key individual so that they may increase 
their stake in Summo and benefit from increases in the value of Summo's 
shares.

2.     ADMINISTRATION

       The Plan will be administered by a committee (the "Committee") of 
Summo's Board of Directors (the "Board"), which will consist of two or more 
members. All members of the Committee shall be non-employee directors who a 
"Disinterested Persons" with regard to Plan administration, within the 
meaning of Rule 16b-3 as promulgated and amended from time to time by the 
United States Securities and Exchange Commission.

       The Committee will be authorized, subject to the provisions of the 
Plan, to adopt such rules and regulations which it deems consistent with the 
Plan's provisions and, in its sole discretion, to designate options 
("Options") to purchase shares of Summo pursuant to the Plan. The Committee 
may authorize one or more individuals of Summo to execute, deliver and 
receive documents on behalf of the Committee.

3.     ELIGIBILITY

       All directors and officers and employees of Summo and its subsidiaries 
will be eligible to receive Options. The term "subsidiaries" for the purpose 
of the Plan will include Summo U.S.A. Corporation, which definition may be 
varied by the Committee to conform with the changing interests of Summo.

       Nothing in the Plan or in any option shall confer any right on any 
individual to continue in the employ of or association with Summo or its 
subsidiaries or will interfere in any way with the right of Summo or 
subsidiaries to terminate at any time the employment of a person who is an 
optionee ("Optionee") under an Option.

4.     SHARES SUBJECT TO OPTION

       The shares to be optioned under the Plan will be authorized but 
unissued Common Shares without par value ("Shares") of Summo.        

       At no time will more than 2,000,000 Shares be under option either 
pursuant to the Plan or pursuant to other incentive stock options issued by 
Summo. The number of Shares under option at any specific time to any one 
Optionee shall not exceed 5% of the issued and outstanding common share 
capital of Summo, subject to adjustment under Section 12 below.

       Shares subject to and not delivered under an Option which expires or 
terminates shall again be available for option under the Plan. The maximum 
number of Shares which may be issued pursuant to

<PAGE>

                                        2

the Plan shall not however exceed 2,000,000 Shares.



5.     GRANTING OF OPTIONS

       The Committee may from time to time at its discretion, subject to the 
provisions of the Plan, determine those eligible individuals to whom Options 
will be granted, the number of Shares subject to such Options, the dates on 
which such Options are to be granted and the expiration of such Options.

       The Committee may, at its discretion, with respect to any Option, 
impose additional terms and conditions which are more restrictive on the 
optionee than those provided for in the Plan.

       Each Option will be evidenced by a written agreement between, and 
executed by, Summo and the individual containing such terms and conditions 
established by the Committee with respect to such Option and will be 
consistent with the provisions of the Plan.

       Options shall be granted to directors only according to the following 
formula:

       (i)    Each director who was a member of the Board of Directors prior to
              January 1, 1996, shall upon adoption of this Plan be issued 
              Options for that number of Shares necessary to bring the aggregate
              number of Shares underlying incentive options issued to such 
              director to 150,000 Shares. The exercise price of such Options 
              shall be determined as provided in Section 6 hereof.

       (ii)   Each director who becomes a member of the Board of Directors after
              January 1, 1996, shall be granted Options for 50,000 Shares upon 
              his or her election or appointment to the Board. The exercise 
              price shall be determined as provided in Section 6 hereof.

       (iii)  Upon the expiration date of any Options issued to a director 
              (regardless of whether such Options were exercised on or prior to
              the expiration date), such director shall be issued Options for an
              additional 50,000 Shares. The exercise price shall be determined 
              as provided in Section 6 hereof. The provisions of this 
              paragraph (iii) shall also apply upon the expiration date of any 
              other incentive stock options issued to a director if at the time
              of such expiration date, the director holds incentive options, 
              including Options, for fewer than an aggregate of 50,000 Shares 
              underlying such options, in which case the director shall be 
              issued that number of Options necessary to bring the aggregate 
              number of Shares underlying incentive options issued to such 
              director at such time to 50,000 Shares. The calculation of 
              incentive options held by any director shall not include any 
              warrants to purchase Summo shares held by a director provided 
              such warrants were issued by Summo in connection with securities 
              offered by Summo.

       (iv)   The foregoing formulas shall not be amended more than once every 
              six months other than to comport with changes in the Internal 
              Revenue Code, the Employee Retirement Income Security Act, or the
              rules thereunder.

       (v)    Additional options may be granted to directors at the discretion 
              of the Committee,

<PAGE>

                                        3

              provided that no director may receive additional options while 
              serving on the Committee if the receipt of such options would 
              cause him to cease to be a Disinterested Person.

6.     OPTION PRICE

       The price per Share at which Shares may be purchased upon the exercise 
of an Option (the "Option Price") will not be lower that the "market price" 
of the Shares on The Toronto Stock Exchange (the "TSE") at the time of grant. 
In the context of the Plan, "market price" means the closing price of Summo's 
shares on the TSE at the close of trading which immediately preceded the time 
that the option was granted. If the shares of Summo do not trade on such day, 
the "market price" shall be the average of the bid and ask prices on the 
previous trading day.

7.     TERM OF OPTION

       The maximum term of any Option will be 10 years.

       The Option Price will be paid in full at the time of exercise of the 
Option and no Shares will be delivered until full payment is made.

       An Optionee will not be deemed the holder of the Shares subject to his 
Option until the Shares are delivered to him.

8.     TRANSFERABILITY OF OPTIONS

       An Option may not be assigned. During the lifetime of an Optionee, the 
Option may be exercised only by the Optionee.

9.     TERMINATION OF EMPLOYMENT

       Upon termination of employment for any reason except death or 
retirement or failure of reelection as a director or failure to be 
re-appointed an officer of Summo, an Optionee may, at any time within 30 days 
after the date of termination but not later than the date of expiration of 
the Option, exercise the Option to the extent the Optionee was entitled to do 
so on the date of termination. Any option or portions of Options of 
terminated individuals not so exercised will terminate and again be available 
for future Options under the Plan. A change of employment will not be 
considered a termination so long as the Optionee continues to be employed by 
Summo or its subsidiaries.

10.    DEATH

       Notwithstanding any other provision of this Plan other than the 
maximum of 10 years provided for in Section 7, if any Optionee shall die 
holding an Option which has not been fully exercised, his personal 
representative, heirs or legatees may, at any time within 60 days of grant of 
probate of the will or letters of administration of the estate of the 
decedent or within one year after the date of such death, whichever is the 
lesser time, exercise the Option with respect to the unexercised balance of 
the Shares subject to the Option.

<PAGE>

                                        4

11.     RETIREMENT

        Notwithstanding any other provision of this Plan, if any Optionee 
shall retire or terminate his employment with the consent of the Board under 
circumstances equating retirement, while holding an Option which has not been 
fully exercised, such Optionee may exercise the Option at any time during the 
unexpired term of the Option.

12.     CHANGE IN SHARES

        In the event the authorized common share capital of Summo as 
presently constituted is consolidated into a lesser number of Shares or 
subdivided into a greater number of Shares, the number of Shares for which 
Options are outstanding will be decreased or increased proportionately as the 
case may be and the Option Price will be adjusted accordingly and the 
Optionee will have the benefit of any stock dividend declared during the 
period within which the said Optionee held his Option. Should Summo 
amalgamate or merge with any other company or companies (the right to do so 
being expressly reserved) whether by way of arrangement, sale of assets and 
undertakings or otherwise, then and in each such case the number of shares of 
the resulting corporation to which an Option relates will be determined as if 
the Option has been fully exercised prior to the effective date of the 
amalgamation or merger and the Option Price will be correspondingly increased 
or decreased, as applicable.

13.     CANCELLATION AND RE-GRANTING OF OPTIONS

        The Committee may, with the consent of the Optionee, cancel any 
existing Option, and re-grant the Option at an Option Price determined in the 
same manner as provided in Section 6 hereof, subject to the prior approval of 
the TSE.

14.     AMENDMENT OR DISCONTINUANCE

        The Board may alter, suspend or discontinue the Plan, but may not, 
without the approval of the shareholders of Summo and the TSE, may any 
alteration which would (a) increase the aggregate number of Shares subject to 
Option under the Plan except as provided in Section 12 or (b) decrease the 
Option Price except as provided in Section 12. Notwithstanding the foregoing, 
the terms of an existing Option may not be altered, suspended or discontinued 
without the consent in writing of the Optionee.

15.     INTERPRETATION

        The Plan will be construed according to the laws of the Province of 
British Columbia.

16.     LIABILITY

        No member of the Committee or any director, officer or employee of 
Summo will be personally liable for any act taken or omitted in good faith in 
connection with the Plan.

                                 Schedule "A"
- --------------------------------------------------------------------------------

                         SUMMO MINERALS CORPORATION
                    EMPLOYEE INCENTIVE STOCK OPTION PLAN

1.  PURPOSE

    The purpose of the Employee Incentive Stock Option Plan (the "Plan") is 
to promote the profitability and growth of SUMMO MINERALS CORPORATION 
("Summo") by facilitating the efforts of Summo and its subsidiaries to obtain 
and retain key individuals. The Plan provides an incentive for and encourages 
ownership of Summo's shares by its key individual so that they may increase 
their stake in Summo and benefit from increases in the value of Summo's 
shares.

2.  ADMINISTRATION

    The Plan will be administered by a committee (the "Committee") of Summo's 
Board of Directors (the "Board"), which will consist of two or more members. 
All members of the Committee shall be non-employee directors who a 
"Disinterested Persons" with regard to Plan administration, within the 
meaning of Rule 16b-3 as promulgated and amended from time to time by the 
United States Securities and Exchange Commission.

    The Committee will be authorized, subject to the provisions of the Plan, 
to adopt such rules and regulations which it deems consistent with the Plan's 
provisions and, in its sole discretion, to designate options ("Options") to 
purchase shares of Summo pursuant to the Plan. The Committee may authorize 
one or more individuals of Summo to execute, deliver and receive documents on 
behalf of the Committee.

3.  ELIGIBILITY

    All directors and officers and employees of Summo and its subsidiaries 
will be eligible to receive Options. The term "subsidiaries" for the purpose 
of the Plan will include Summo U.S.A. Corporation, which definition may be 
varied by the Committee to conform with the changing interests of Summo.

    Nothing in the Plan or in any option shall confer any right on any 
individual to continue in the employ of or association with Summo or its 
subsidiaries or will interfere in any way with the right of Summo or 
subsidiaries to terminate at any time the employment of a person who is an 
optionee ("Optionee") under an Option.

4.  SHARES SUBJECT TO OPTION

    The shares to be optioned under the Plan will be authorized but unissued 
Common Shares without par value ("Shares") of Summo.

     At no time will more than 2,000,000 Shares be under option either 
pursuant to the Plan or pursuant to other incentive stock options issued by 
Summo. The number of Shares under option at any specific time to any one 
Optionee shall not exceed 5% of the issued and outstanding common share 
capital of Summo, subject to adjustment under Section 12 below.

    Shares subject to and not delivered under an Option which expires or 
terminates shall again be available for option under the Plan. The maximum 
number of Shares which may be issued pursuant to

<PAGE>

                                       2

the Plan shall not however exceed 2,000,000 Shares.

5.  GRANTING OF OPTIONS

    The Committee may from time to time at its discretion, subject to the 
provisions of the Plan, determine those eligible individuals to whom Options 
will be granted, the number of Shares subject to such Options, the dates on 
which such Options are to be granted and the expiration of such Options.

    The Committee may, at its discretion, with respect to any Option, impose 
additional terms and conditions which are more restrictive on the optionee 
than those provided for in the Plan.

    Each Option will be evidenced by a written agreement between, and 
executed by, Summo and the individual containing such terms and conditions 
established by the Committee with respect to such Option and will be 
consistent with the provisions of the Plan.

    Options shall be granted to directors only according to the following 
formula:

      (i)  Each director who was a member of the Board of Directors prior to 
           January 1, 1996, shall upon adoption of this Plan be issued 
           Options for that number of Shares necessary to bring the aggregate 
           number of Shares underlying incentive options issued to such 
           director to 150,000 Shares. The exercise price of such Options 
           shall be determined as provided in Section 6 hereof.

     (ii)  Each director who becomes a member of the Board of Directors after 
           January 1, 1996, shall be granted Options for 50,000 Shares upon 
           his or her election or appointment to the Board. The exercise 
           price shall be determined as provided in Section 6 hereof.

    (iii)  Upon the expiration date of any Options issued to a director 
           (regardless of whether such Options were exercised on or prior to 
           the expiration date), such director shall be issued Options for an 
           additional 50,000 Shares. The exercise price shall be determined 
           as provided in Section 6 hereof. The provisions of this paragraph 
           (iii) shall also apply upon the expiration date of any other 
           incentive stock options issued to a director if at the time of 
           such expiration date, the director holds incentive options, 
           including Options, for fewer than an aggregate of 50,000 Shares 
           underlying such options, in which case the director shall be 
           issued that number of Options necessary to bring the aggregate 
           number of Shares underlying incentive options issued to such 
           director at such time to 50,000 Shares. The calculation of 
           incentive options held by any director shall not include any 
           warrants to purchase Summo shares held by a director provided such 
           warrants were issued by Summo in connection with securities 
           offered by Summo.

     (iv)  The foregoing formulas shall not be amended more than once every 
           six months other than to comport with changes in the Internal 
           Revenue Code, the Employee Retirement Income Security Act, or the 
           rules thereunder.

      (v)  Additional options may be granted to directors at the discretion 
           of the Committee,

<PAGE>

                                       3

           provided that no director may receive additional options while 
           serving on the Committee if the receipt of such options would 
           cause him to cease to be a Disinterested Person.

6.  OPTION PRICE

    The price per Share at which Shares may be purchased upon the exercise of 
an Option (the "Option Price") will not be lower that the "market price" of 
the Shares on The Toronto Stock Exchange (the "TSE") at the time of grant. In 
the context of the Plan, "market price" means the closing price of Summo's 
shares on the TSE at the close of trading which immediately preceded the time 
that the option was granted. If the shares of Summo do not trade on such day, 
the "market price" shall be the average of the bid and ask prices on the 
previous trading day.

7.  TERM OF OPTION

    The maximum term of any Option will be 10 years.

    The Option Price will be paid in full at the time of exercise of the 
Option and no Shares will be delivered until full payment is made.

    An Optionee will not be deemed the holder of the Shares subject to his 
Option until the Shares are delivered to him.

8.  TRANSFERABILITY OF OPTIONS

    An Option may not be assigned. During the lifetime of an Optionee, the 
Option may be exercised only by the Optionee.

9.  TERMINATION OF EMPLOYMENT

Upon termination of employment for any reason except death or retirement or 
failure of re-election as a director or failure to be re-appointed an 
officer of Summo, an Optionee may, at any time within 30 days after the date 
of termination but not later than the date of expiration of the Option, 
exercise the Option to the extent the Optionee was entitled to do so on the 
date of termination. Any option or portions of Options of terminated 
individuals not so exercised will terminate and again be available for future 
Options under the Plan. A change of employment will not be considered a 
termination so long as the Optionee continues to be employed by Summo or its 
subsidiaries.

10. DEATH

    Notwithstanding any other provision of this Plan other than the maximum 
of 10 years provided for in Section 7, if any Optionee shall die holding an 
Option which has not been fully exercised, his personal representative, heirs 
or legatees may, at any time within 60 days of grant of probate of the will 
or letters of administration of the estate of the decedent or within one year 
after the date of such death, whichever is the lesser time, exercise the 
Option with respect to the unexercised balance of the Shares subject to the 
Option.


<PAGE>

                                       4

11. RETIREMENT

    Notwithstanding any other provision of this Plan, if any Optionee shall 
retire or terminate his employment with the consent of the Board under 
circumstances equating retirement, while holding an Option which has not been 
fully exercised, such Optionee may exercise the Option at any time during the 
unexpired term of the Option.

12. CHANGE IN SHARES

    In the event the authorized common share capital of Summo as presently 
constituted is consolidated into a lesser number of Shares or subdivided into 
a greater number of Shares, the number of Shares for which Options are 
outstanding will be decreased or increased proportionately as the case may be 
and the Option Price will be adjusted accordingly and the Optionee will have 
the benefit of any stock dividend declared during the period within which the 
said Optionee held his Option. Should Summo amalgamate or merge with any 
other Company or companies (the right to do so being expressly reserved) 
whether by way of arrangement, sale of assets and undertakings or otherwise, 
then and in each such case the number of shares of the resulting corporation 
to which an Option relates will be determined as if the Option has been fully 
exercised prior to the effective date of the amalgamation or merger and the 
Option Price will be correspondingly increased or decreased, as applicable.

13. CANCELLATION AND RE-GRANTING OF OPTIONS

    The Committee may, with the consent of the Optionee, cancel any existing 
Option, and re-grant the Option at an Option Price determined in the same 
manner as provided in Section 6 hereof, subject to the prior approval of the 
TSE.

14. AMENDMENT OR DISCONTINUANCE

    The Board may alter, suspend or discontinue the Plan, but may not, 
without the approval of the shareholders of Summo and the TSE, may any 
alteration which would (a) increase the aggregate number of Shares subject to 
Option under the Plan except as provided in Section 12 or (b) decrease the 
Option Price except as provided in Section 12. Notwithstanding the foregoing, 
the terms of an existing Option may not be altered, suspended or discontinued 
without the consent in writing of the Optionee.

15. INTERPRETATION

    The Plan will be construed according to the laws of the Province of 
British Columbia,

16. LIABILITY

    No member of the Committee or any director, officer or employee of Summo 
will be personally liable for any act taken or omitted in good faith in 
connection with the Plan.

be exercised during the lifetime of the Optionee only by the Optionee.

5.   If the Optionee should die while he is either a director or an employee of
the Company the option herein granted may then be exercised by his legal heirs
or personal representatives to the same extent as if the Optionee were alive and
either a director or an employee of the Company for a period of six (6) months
after the death of the Optionee, but only for such shares as the Optionee was
entitled to at the date of the death of the Optionee.

6.   The Optionee represents and warrants that he is either a director or an
employee of the Company or an affiliate thereof. Subject to paragraph 5 hereof,
the option herein granted shall cease and become null and void following the
tenth day after which the Optionee ceases to act as an employee of the Company.

7.   The provisions of this agreement and the exercise of the rights 
hereinbefore granted to the Optionee are subject to the approvals of the 
British Columbia Securities Commission or, if listed thereon, the TSE and the

then this agreement shall from that date be null and void and of no further 
force and effect.

Re: Commitment - Lisbon Valley Copper Project (the "Project") $45 Million 
Financing

Dear Mr. Hahn: 


We are pleased to inform you that we have received credit approval for the 
above referenced $45 million project financing facility (the "Facility"). 
This letter will serve as ING (US) Capital Corporation's ("ING Capital") 
commitment to underwrite $27.5 million of the Facility, subject to the terms 
and conditions set forth in the attached Definitive Term Sheet and completion 
of ING Capital's legal and technical due diligence. It is our understanding 
that the Facility's co-underwriter, Heller Financial, Inc. has also received 
the requisite credit approvals and will, under separate cover, confirm to you 
their firm commitment to underwrite $17.5 million of the Facility.

As discussed, the attached Definitive Term Sheet incorporates the revisions 
agreed to by ING Capital, including the following:

1.  The Ore Reserves will be increased to permit at least two additional      
    years of production as a condition of Commercial Completion.

2.  The Economic Test for Commercial Completion will require achieving the    
    following Debt Coverage Ratios:

              Life of Loan                            at least 1.50 
              Life of Reserves                        at least 1.75

3.  Following Commercial Completion, distributions of Cash Flow              
    Participation will be permitted so long as there exist no events of       
    default and the Debt Coverage Ratio is at least 1.50.

We are at this time not able to commit to the $7.0 million hedging facility. 
We see this facility as being in the best long term interest of the Borrower. 
We propose to revisit this matter and to give it consideration within the 
next twelve months.

FINAL             No later than December 31, 2005. 
MATURITY:

SCHEDULED         Facility repayments shall be in quarterly installments      
REPAYMENTS:       commencing six months after Commercial Completion, but not  
                  later than March 31, 1999. The anticipated repayment        
                  schedule (Exhibit I) is structured in recognition of the    
                  Project's currently projected Cash Available for Debt       
                  Service.

MANDATORY         Mandatory Repayments equal to the Prescribed Percentage of  
REPAYMENTS:       Excess Cash Flow will be made quarterly within 45 days of   
                  quarter-end. Mandatory Repayments will be applied to        
                  Scheduled Repayments in their inverse order of maturity.    
                  Following achievement of Commercial Completion, the        
                  Prescribed Percentage will be 50%, except that, if the then 
                  Ore Reserves provide for a mine life of 24 months or more   
                  beyond Final Maturity, then, if the lower of the Debt       
                  Coverage Ratio and Historic Debt Coverage Ratio is between  
                  1.5 and 2.0, the Prescribed Percentage for that quarter     
                  will be 25%, and if it is greater than 2.0, then 0%.

VOLUNTARY         The Borrower may prepay all or a portion of outstandings    
REPAYMENTS:       without penalty, such prepayments to be applied in their    
                  inverse order of maturity. The Borrower will reimburse      
                  Lenders for funding costs associated with making repayments 
                  on non-interest rollover dates.

EXCESS CASH       Cash Available for Debt Service less Debt Service. 
FLOW:

CASH AVAILABLE    Gross revenue less all associated royalties, cash           
FOR DEBT          production costs, taxes, non-discretionary capital          
SERVICE:          expenditures, and working capital changes. 

DEBT SERVICE:     Scheduled principal and interest payments.

ORE RESERVES:     Those ore reserves certified by the Independent Engineer as 
                  being proven and probable.

CAPITAL           Those expenses necessary for the development of the Project 
EXPENDITURES:     and which will be more fully described in the Development   
                  Plan.

DEBT COVERAGE     Debt Coverage Ratio shall be the ratio of Cash Available    
RATIO:            For Debt Service plus the balance in the Debt Service       
                  Reserve to Debt Service through the Facility's Final        
                  Maturity as projected under the Development and Operating   
                  Plan. Gross revenue will be calculated using the actual     
                  hedged price for all future hedged production, and the      
                  unhedged price for the balance. The unhedged price will be  
                  the lesser of (1) the average of the historic 12 monthly    
                  spot price, (2) the then spot price and (3) the average of  
                  the future 12 month LME forward price.

                         PHYSICAL COMPLETION EXAMPLE

1.  The plant, equipment, and related infrastructure have been completed and  
    installed essentially as described in the Feasibility Study               
    [Development and Operating Plan and/or EPCM Contract] and shall have been 
    commissioned.

2.  All construction costs have been paid in full and the Project shall be    
    free and clear of any lien, charge or encumbrance of any kind not         
    permitted under the loan documents and free and clear of any              
    materialmen's liens arising in connection with the construction of the    
    Project.

3.  All governmental, regulatory and third party permits, licenses, consents  
    and approvals necessary for a continuous operation of the Project in      
    accordance with the Feasibility Study are in full force and effect.

4.  Management and a work force in appropriate numbers and with the           
    appropriate qualifications are on the job in accordance with good mine    
    operating practice.

5.  The required insurance is in full force and effect as certified by the    
    Independent Insurance Advisor.
                                       
                      COMMERCIAL COMPLETION TEST EXAMPLES

Commercial Completion shall occur on the date on which (a) there is no Default
or Event of Default and (b) the Independent Engineer submits to the Agent a
certificate stating that (i) the conditions set forth below have occurred and
are correct and (ii) the conditions required for Physical Completion continue to
be satisfied by the Borrower.

1.  For 30 consecutive days, after pregnant leach solution ("PLS")            
    strengths and flows have been built up to permit the continuous, full     
    operation of the solvent extraction and electrowinning plants, the        
    Project has produced at least [xx] tons of Class I copper cathodes        
    meeting LME "A" Grade specifications ("Product") during which period such 
    production has totaled at least [yy] tons for 10 consecutive days.

2.  For 90 consecutive days following satisfaction of the test set forth in   
    paragraph 1 above, cumulative production of Product has been no less than 
    90% of cumulative copper cathode production calculated in accordance with 
    the Feasibility Study to be recoverable from the actual ore placed and    
    leached on the heap leach pad since Physical Completion.
                                       
                                  page 8 of 9

<PAGE>

3.  The Ore Reserve as defined in the Feasibility Study has been increased in 
    an amount sufficient to allow at least an additional two years of full    
    production;

4.  The cumulative grade, tonnage and contained copper of at least [X,000,000]
    consecutive tons measured by the plant head sampling systems have each    
    been no less than 90 percent of the cumulative grade, tonnage and         
    contained copper of Ore Reserves fed to the plant, such Ore Reserves,     
    together with Ore Reserves within stockpiles and planned open pits, being 
    sufficient to sustain no less than 90% of the ore and Product production  
    forecasted by the Feasibility Study.

5.  For 30 consecutive days within the test period referenced in paragraph 2  
    above, aggregate operating costs per ton of ore mined and processed and   
    per pound of Product produced have each been less than 110% of the        
    Feasibility Study's unescalated unit operating costs projected for the    
    Ore Reserves mined and processed. Operating costs shall include all       
    direct and indirect cash costs incurred by the Project toward the         
    production and sale of Product.

6.  For 30 consecutive days within the test period referenced in paragraph 3  
    above, at least (Y,000,000) tons of ore and waste have been mined and     
    delivered to their respective crusher, stockpile and waste disposal areas 
    during which time such mining rate has exceeded (Z,000) ton per day for   
    10 days.

7.  For 30 consecutive days within the test period referenced in paragraph 3  
    above, at least (A,000) tons of ore has been crushed to 100% at minus (P) 
    in. during which time such crushing rate has exceeded (B,000) tons per    
    day for 10 days.

8.  For 30 consecutive days within the test period referenced in paragraph 3  
    above, at least (C,000) tons of crushed ore has been conveyed and stacked 
    on the heap leach pads during which time such delivery rate has exceeded  
    (D,000) tons per day for 10 days.

9.  For 30 consecutive days within the test period referenced in paragraph 3  
    above, the flowrate of PLS to the solvent extraction circuit shall        
    average the equivalent of at least (H,000) kilograms per hour of copper   
    contained in PLS.

ECONOMIC TEST

In lieu of the tests set forth in paragraphs 5 through 8 above, the Borrower 
may elect to satisfy an economic test to be agreed between the Borrower and 
the Lenders. For example, to meet the Economic Test, the Debt Coverage Ratio 
shall be shown to be in excess of 1.50 for the period remaining to Final 
Maturity and 1.75 for the period to end of reserve life.
