Item 5.  Other Events

     On February 4, 1997, USMX, Inc. (the "Company" or
"USMX") entered into an Agreement and Plan of Merger (the
"Merger Agreement") with Dakota Mining Corporation
("Dakota") and Dakota Merger Corporation, a wholly owned
subsidiary of Dakota.  Pursuant to the Merger Agreement,
each holder of 1.1 outstanding shares of USMX common stock
will receive one share of Dakota common stock in a tax-free
reorganization to be effected as a reverse triangular merger
in which Dakota Merger Corporation will merge into the
Company and the Company would become an indirect wholly
owned subsidiary of Dakota at the effective time of the
Merger.  The consummation of the Merger is subject to
various conditions, including completion of a $5 million
loan by Dakota to the Company, stockholder and creditor
approval, review by regulatory authorities and other
conditions.  The Merger Agreement is included as Exhibit 2
to this Report.

     In connection with the Merger, USMX granted an option
to Dakota to purchase up to 810,000 shares of USMX common
stock at US$1.75 per share, which would be exercisable in
the event that USMX determines not to engage in the Merger
with Dakota due to a transaction with another entity.  The
Option Agreement is included as Exhibit 10(a) to this
Report.

     In connection with the Merger, Pegasus Gold Inc.,
holder of approximately 30% of USMX's common stock, entered
into a Support Agreement with USMX and Dakota.  Subject to
certain conditions, Pegasus Gold Inc. has agreed in the
Support Agreement to support the proposed Merger.  The
Support Agreement is included as Exhibit 10(b) to this
Report.

NOW, THEREFORE, in consideration of the mutual benefits to be
derived and the representations and warranties, conditions and
promises herein contained, and intending to be legally bound
hereby, the Parties agree as follows:


ARTICLE I
                            GENERAL

I.1  Merger.  In accordance with the terms and provisions of this
Agreement, the GCL, and other applicable Law, Merger Corp shall
be merged with and into USMX (the "Merger"), and USMX shall be,
and is hereinafter sometimes referred to as, the "Surviving
Corporation." Merger Corp and USMX shall be, and are hereinafter
sometimes referred to as, the "Constituent Corporations."

I.2  Charter and By-laws; Directors and Officers.  From and after
the Effective Time:

     (a)  the Certificate of Incorporation and the By-laws of
Merger Corp shall continue in full force and effect as the
Certificate of Incorporation and the By-laws of the Surviving
Corporation; and

     (b)  the directors and officers of Merger Corp shall be the
directors and officers of the Surviving Corporation.

I.3  No Separate Identity.  Except as hereinafter specifically
set forth, the identity, existence, corporate organization,
purposes, powers, objects, franchises, privileges, rights and
immunities of Merger Corp shall be merged with and into USMX, and
USMX, as the Surviving Corporation, shall be fully vested
therewith.  The separate existence and the corporate organization
of Merger Corp, except insofar as they may continue by statute,
shall cease as of the Effective Time.

I.4  Effectiveness.  The Merger shall not become effective until,
and shall become effective at, the point in time at which
Certificate of Merger (the "Certificate of Merger") in accordance
with the terms of this Agreement and in substantially the form
attached as Exhibit 1.4, and in accordance with Section 251 of
the GCL, shall have been executed by the Constituent Corporations
and filed with the Secretary of State of the State of Delaware.
The time when the Merger shall become effective as aforesaid is
herein called the "Effective Time." The Parties shall cause the
Certificate of Merger to be executed and filed as aforesaid on
the Closing Date upon the satisfaction or waiver of the
conditions contained in Articles VIII, IX, and X.

I.5  Conversion of Shares.  As of the Effective Time, all
outstanding USMX Shares shall be converted automatically into the
right to receive Dakota Shares in the ratio of 1.10 USMX Shares
to one Dakota Share; and each share of the common stock of Merger
Corp shall be converted automatically into the right to receive
one share of common stock of the Surviving Corporation.

I.6  Treasury Shares, Etc.  Each USMX Share which, immediately
prior to the Effective Time, is held by (a) USMX as treasury
stock, (b) any other member of the USMX Group, or (c) any member
of the Dakota Group, shall be canceled and no consideration shall
be delivered with respect thereto.

I.7  Warrants, Options, Etc.  Each warrant, option, or other
right to acquire USMX Shares as of the Effective Time shall be
converted into a warrant, option, or other right to acquire
Dakota Shares based on the conversion ratio set forth in
Section 1.5, with the exercise price associated therewith, if
any, being adjusted proportionately.

I.8  No Fractional Shares.  Fractional Dakota Shares shall not be
issued in exchange for USMX Shares.  Except for operation of this
Section, if the conversion of shares pursuant to Section 1.5
would result in any stockholder of USMX being entitled to receive
a fractional interest in a Dakota Share, such stockholder shall
receive a single whole Dakota Share in lieu of such fractional
interest.

I.9  Stock Transfer Books.  The stock transfer books of USMX
shall be closed as of the Effective Time, and no transfer of USMX
Shares shall be made or consummated thereafter except by the
Surviving Corporation.

I.10 Exchange of Certificates.

     (a)  Dakota and USMX shall authorize Montreal Trust Company
of Canada (or such other Person as shall be reasonably acceptable
to Dakota and USMX) to act as Exchange Agent hereunder (the
"Exchange Agent").  As soon as practicable after the Effective
Time, Dakota shall deposit with the Exchange Agent for the
benefit of the holders of certificates which immediately prior to
the Effective Time represented USMX Shares (the "Certificates")
certificates representing Dakota Shares (together with any
dividends or distributions with respect thereto payable as
provided in Section 1.10(c), the "Exchange Fund") issuable
pursuant to Section 1.5 in exchange for outstanding USMX Shares.

     (b)  As soon as practicable after the Effective Time, the
Exchange Agent shall mail to each holder of record of a
Certificate whose shares were converted pursuant to Section 1.5
into Dakota Shares a letter of transmittal (which shall specify
that delivery shall be effected, and risk of loss and title to
the Certificates shall pass, only upon actual and proper delivery
of the Certificates to the Exchange Agent, shall contain
instructions for use in effecting the surrender of the
Certificates in exchange for certificates representing Dakota
Shares, and shall be in such form and contain such other
provisions as Dakota and USMX may reasonably specify).  Upon
surrender of a Certificate for cancellation to the Exchange
Agent, together with such letter of transmittal, duly executed,
the holder of such Certificate shall be entitled to receive in
exchange therefor a certificate representing that number of whole
Dakota Shares which such holder has the right to receive pursuant
to this Article, and the Certificate so surrendered shall
forthwith be canceled.  Until surrendered as contemplated by this
Section, each Certificate shall, at and after the Effective Time,
be deemed to represent only the right to receive, upon surrender
of such Certificate, the certificate representing the appropriate
number of Dakota Shares and certain dividends and other
distributions as contemplated by Section 1.10(c).

     (c)  No dividends or other distributions that are declared
on or after the Effective Time on Dakota Shares or are payable to
the holders of record thereof on or after the Effective Time will
be paid to persons entitled by reason of the Merger to receive
certificates representing Dakota Shares until such persons
surrender their Certificates, as provided in Section 1.10(b).
Subject to the effect of applicable Law, there shall be paid to
such record holders of the certificates representing such Dakota
Shares (1) at the time of such surrender or as promptly as
practicable thereafter, the amount of any dividends or other
distributions theretofore paid with respect to whole Dakota
Shares and having a record date on or after the Effective Time
and a payment date prior to such surrender and (2) at the
appropriate payment date or as promptly as practicable
thereafter, the amount of dividends or other distributions
payable with respect to whole Dakota Shares and having a record
date on or after the Effective Time but prior to surrender and a
payment date subsequent to surrender.  In no event shall the
person entitled to receive such dividends or other  distributions
be entitled to receive interest on such dividends or other
distributions.  If any cash or certificate representing Dakota
Shares is to be paid to or issued in a name other than that in
which the Certificate surrendered in exchange therefor is
registered, it shall be a condition of such exchange that the
Certificate so surrendered shall be properly endorsed and
otherwise in proper form for transfer and that the person
requesting such exchange shall pay to the Exchange Agent any
transfer or other taxes required by reason of the issuance of
certificates for such Dakota Shares in a name other than that of
the registered holder of the Certificate surrendered, or shall
establish to the satisfaction of the Exchange Agent that such tax
has been paid or is not applicable.

     (d)  Any portion of the Exchange Fund which remains
undistributed to the former stockholders of USMX for one year
after the Effective Time shall be delivered to Dakota, upon
demand of Dakota, and any former stockholders of USMX who have
not theretofore complied with this Section shall thereafter look
only to Dakota for payment of their claim for Dakota Shares and
any dividends or distributions with respect to Dakota Shares.
Neither Dakota nor  USMX shall be liable to any holder of USMX
Shares for Dakota Shares (or dividends or distributions with
respect thereto) delivered to a public official pursuant to any
applicable abandoned property, escheat, or similar Law.

I.11 Directors of Dakota.  Immediately following the Effective
Time, Dakota shall increase the number of directors comprising
its Board of Directors to nine; Dakota shall allow USMX to
designate three directors and Pegasus Gold Inc. to designate one
director to fill the vacancies created by increasing the board
size, subject to Dakota's approval, with Donald P. Bellum as one
of the three USMX designated directors and the Chairman of the
Board.

each USMX Group Member to, refrain from doing, or causing to be

on such date (except to the extent that such representations and
warranties are, by their terms, made expressly as of the date of
this Agreement).

Transactions as required by the GCL and, to the extent
applicable, the Nasdaq National Market System.  USMX shall use
its best efforts to obtain its stockholders' approval of the

shall not permit the respective officers, employees,
representatives, and other Advisors of the USMX Group to,
directly or indirectly, (1) solicit, initiate, or engage in
discussions or negotiations with any person, encourage submission
of any inquiries, proposals, or offers by, or take any other
action intended or designed to facilitate the efforts of any
person, other than Dakota, relating to the possible acquisition
of, or business combination with, USMX or any of its Subsidiaries
(whether by way of merger, consolidation, take-over bid, tender
offer, purchase of shares, purchase of assets, or otherwise) or
any material portion of its or their shares of capital stock or
assets (with any such efforts by any such person, including a
firm proposal to make such an acquisition or combination, herein
referred to as a "Competing Transaction"), (2) provide non-public
information with respect to USMX or any USMX Group Member, or
afford any access to the properties, books, or records of the
same, to any Person, other than Dakota, relating to a possible
Competing Transaction by any person other than Dakota, (3) make
or authorize any statement, recommendation, or solicitation in
support of any possible Competing Transaction by any Person other

to any of the foregoing.

     (b)  Notwithstanding paragraph (a) above, prior to the
approval of the Merger by the holders of USMX Shares, nothing
contained in this Section shall prevent the Board of Directors of
USMX (or its agents pursuant to its instructions) from
(1) engaging in discussions or negotiations with (but not
soliciting or initiating such discussions or negotiations or
encouraging inquiries from) a party concerning an unsolicited
proposal for a Competing Transaction, (2) providing non-public
information with respect to the USMX Group that has previously
been provided to Dakota, or (3) making any statement or
recommendation in support of any Competing Transaction, in each
case if the USMX Board of Directors first determines in good
faith, after consultation with and receiving written advice from
its outside legal counsel (which advice need not constitute an
opinion), that such action is required by reason of the fiduciary
duties of the directors of USMX to the USMX stockholders under
applicable Law; provided that in each such event USMX first
notifies Dakota of such determination and provides Dakota with
the fact that it is furnishing information to, or entering into
discussions or negotiations with, a person or entity, and USMX
keeps Dakota informed of the status of any such discussions or
negotiations.  If USMX or any USMX Group Member receives any
unsolicited offer or proposal to enter negotiations relating to a
Competing Transaction, USMX shall immediately notify Dakota
thereof.  USMX shall be responsible for any breach of this
Section by any USMX Group Member or any of their respective
directors, officers, employees, representatives, or other
Advisors or Affiliates.

     (c)  Dakota may, in its sole discretion, prior to the
holding of USMX Stockholders' Meeting, amend the terms of this
Agreement to increase the consideration payable to holders of
USMX Shares pursuant thereto, by delivering such amended terms to
USMX before the holding of such meeting, provided that such
amendment shall not materially delay the consummation of the
Merger.

     (d)  Notwithstanding any other provisions hereof, USMX shall
not (1) enter into a Competing Transaction until at least (A) ten
Business Days following the first notification by USMX to Dakota
that it has entered into discussions with a third party in
respect of such Competing Transaction and (B) five Business Days
following delivery of written notice by USMX to Dakota of the
identity of the parties to and the terms and conditions of such
Competing Transaction or (2) for a period of ten Business Days
following termination of this Agreement pursuant to Section 11.2
hereof, grant or agree to grant to any third party, in connection
with a Competing Transaction, an option to purchase treasury
securities or assets of USMX or any USMX Group Member, pay or
agree to pay to any such third party, termination, expense
reimbursement, "topping" or similar fees in the event of non-
consummation of such Competing Transaction or otherwise commit to
any inducement to any such third party.

V.13 Cooperation.  USMX shall, and shall use its best efforts to
cause the USMX Group to, cooperate with Dakota in all reasonable
respects in connection with the transaction described in Section
10.10 (including preparation and filing of preliminary and final
prospectuses in Canada in connection therewith).

VI.3 Representations and Warranties.  Dakota shall, and shall
cause each Dakota Group Member to, refrain from doing, or causing
to be done, anything which would cause the representations and
warranties set forth in Article III from being true, complete,
and accurate in all material respects on the Closing Date as if
made on such date (except to the extent that such representations
and warranties are, by their terms, made expressly as of the date
of this Agreement).

Members to, refrain from doing any act or omitting to do any act,
or permitting any act or omission to act, which will cause a
material breach of any Contract or this Agreement.

days after the end of each fiscal month ending after the date
hereof an unaudited consolidated and consolidating balance sheet
and income statement of the Dakota Group for each such period.

for the purpose of voting on the adoption of this Agreement and
the Transactions as required by The Toronto Stock Exchange.
Dakota shall use its best efforts to obtain its shareholders'
approval of the foregoing, including without limitation
specifically recommending that its shareholders vote to approve

party offer (which Dakota shall not encourage or solicit), Dakota
shall be free, with respect to its recommendation, to exercise
its fiduciary duties to its shareholders.

VI.12     Employee Benefit Plans.  Each of the Parties agrees to
use its reasonable efforts to coordinate the conversion or merger
of any employee benefit plans of USMX into Dakota plans, to the
extent that such plans may exist, to provide any and all
employees of the USMX Group who become employees of the Dakota
Group with the same employee benefits uniformly offered to
employees of such Dakota Group Member.  Dakota shall use its best
efforts to ensure that any and all employees of the USMX Group
who become employees of the Dakota Group are not subject to any
pre-existing condition requirement under Dakota's medical

VI.13     Indemnification; Directors' and Officers' Insurance.

     (a)  In the event of any threatened or actual claim, action,
suit, proceeding, or investigation, whether civil, criminal or
administrative, including, without limitation, any such claim,
action, suit, proceeding, or investigation in which any person
who is now, or has been at any time prior to the date of this
Agreement, a director or officer of any USMX Group Member (for
purposes of this Section the "Indemnified Parties") is, or is
threatened to be, made a party based in whole or in part on, or
arising in whole or in part out of, or pertaining to (1) the fact
that he is or was a director or officer of any USMX Group Member
or any of their respective  predecessors or is or was serving at
the request of any such party as a director, officer, employee,
fiduciary, or agent of another corporation, partnership, trust or
other enterprise, or (2) this Agreement or any of the
transactions contemplated hereby, whether in any case asserted or
arising before or after the Effective Time, the appropriate
Dakota Group Member will after the Effective Time cooperate and
use its best efforts to defend against and respond thereto.  It
is understood and agreed that after the Effective Time, the
appropriate Dakota Group Member shall indemnify and hold harmless
(as and to the full extent permitted by applicable Law and to the
full extent USMX would have been required to indemnify such
Indemnified Party had such claim, action, suit, proceeding, or
investigation been finally determined prior to the Effective
Time) each such Indemnified Party against any Liability or
Penalty in connection with any such threatened or actual claim,
action, suit, proceeding, or investigation, and shall advance
reasonable litigation expenses incurred by Indemnified Parties,
and in the event of any such threatened or actual claim, action,
suit, proceeding, or investigation (whether asserted or arising
before or after the Effective Time), the Indemnified Parties may
retain counsel reasonably satisfactory to them after consultation
with Dakota; provided, however, (A) the indemnifying entity shall
have the right to assume the defense thereof and upon such
assumption the appropriate Dakota Group Member shall not be
liable to any Indemnified Party for any legal expenses of other
counsel or any other expenses subsequently incurred by any
Indemnified Party in connection with the defense thereof, except
that if the indemnifying entity elects not to assume such defense
or counsel for the Indemnified Parties reasonably advises that
there are issues which raise conflicts of interest between the
indemnifying entity and the Indemnified Parties, the Indemnified
Parties may retain counsel reasonably satisfactory to them after
consultation with Dakota, and the indemnifying entity shall pay
the reasonable fees and expenses of such counsel for the
Indemnified Parties, (B) the indemnifying entity shall be
obligated pursuant to this paragraph to pay for only one firm of
counsel for all Indemnified Parties, (C) the indemnifying entity
shall not be liable for any settlement effected without its prior
written consent, and (D) the indemnifying entity shall have no
obligation hereunder to any Indemnified Party when and if a court
of competent jurisdiction shall ultimately determine, and such
determination shall have become final and nonappealable, that
indemnification of such Indemnified Party in the manner
contemplated hereby is prohibited by applicable Law.  Any
Indemnified Party wishing to claim Indemnification under this
Section, upon learning of any such claim, action, suit,
proceeding or investigation, shall notify Dakota thereof,
provided that the failure to so notify shall not affect the
obligations of the indemnifying entity under this Section except
to the extent such failure to notify materially prejudices such
indemnifying entity.  The obligations under this Section shall
continue in full force and effect for a period of six years from
the Effective Time; provided, however, that all rights to
indemnification in respect of any claim asserted or made within
such period shall continue until the final disposition of such
claim.

     (b)  Dakota shall use commercially reasonable efforts to
cause the persons serving as officers and directors of USMX
immediately prior to the Effective Time to be covered for a
period of six years from the Effective Time by the directors' and
officers' liability insurance policy currently maintained by the
Dakota Group with respect to acts or omissions occurring prior to
the Effective Time which were committed by such officers and
directors in their capacity as such; provided that in no event
shall Dakota or any Dakota Group Member be required to obtain any
new or additional directors' and officers' liability insurance
policies to accomplish the foregoing.

     (c)  In the event Dakota or any of its successors or assigns
(1) consolidates with or merges into any other Person and shall
not be the continuing or surviving corporation or entity of such
consolidation or merger, or (2) transfers or conveys all or
substantially all of its properties and assets to any Person,
then, and in each such case, to the extent necessary to
effectuate the purposes of this Section, Dakota shall use
commercially reasonable efforts to make proper provision so that
the successors and assigns of Dakota assume the obligations set
forth in this Section.

     (d)  The provisions of this Section are intended to be for
the benefit of, and shall be enforceable by, each Indemnified
Party and his or her heirs and representatives.

VI.14     Assumption of Existing Agreements Relating to
Employment.

     (a)  Following the Effective Time, the Surviving Corporation
shall honor in accordance with their terms all employment,
severance, stock option, and other compensation agreements and
arrangements existing prior to the execution of this Agreement,
which are between any USMX Group Member and any director,
officer, or employee thereof and which have been disclosed to
Dakota, and to assume all duties, liabilities, and obligations
under such agreements as in effect at the date of this Agreement.

     (b)  The provisions of this Section are intended to be for
the benefit of, and shall be enforceable by, the directors,
officers, or employees who are parties to the agreements and
arrangements referred to in such section.

VI.15     USMX Stock Options.  At or prior to the Effective Time,
Dakota shall take all corporate action necessary to authorize and
reserve for issuance a sufficient number of Dakota Shares for
delivery upon exercise of options to purchase USMX Shares assumed
by it in accordance with Section 1.7.  As soon as practicable
after the Effective Time, Dakota shall file a registration
statement on Form S-8 (or any successor or other appropriate
forms), or another appropriate form with respect to the Dakota
Shares subject to such options and shall use its best efforts to
maintain the effectiveness of such registration statements (and
maintain the current status of the prospectus or prospectuses
contained therein) for so long as such options remain
outstanding.

warranties made by USMX and Dakota or Merger Corp, as applicable,
on the date of this Agreement (and as of the Closing Date) and to
have superseded any similarly numbered or named Exhibit hereto
delivered on the date hereof.  The foregoing shall not affect the

or Merger Corp contained in Articles V through X, as applicable,
as such conditions relate to such representations and warranties
prior to giving effect to the delivery of such new or additional
Exhibits (except, in the case of any representation and warranty
qualified by a reference to "Material Adverse Effect," to the

based on any breach of the representations and warranties
contained in Articles II and III, respectively, based upon the
disclosures made in such new or additional Exhibits pursuant to
Section 10.11(a) or if the non-breaching Party or its Affiliates
shall, prior to the Closing, have had knowledge of such breach.


ARTICLE XI
                    CLOSING AND TERMINATION

XI.1 Closing.  The Closing shall take place at the offices of
Parcel, Mauro, Hultin & Spaanstra, P.C., Suite 3600, 1801
California Street, Denver, Colorado 80202, at 9:00 o'clock a.m.
(Denver, Colorado time) (or at such other place and time as the
Parties may otherwise agree), on the Closing Date.

XI.2 Termination of this Agreement.

     (a)  In the event that the Closing shall not have occurred
on or before the Termination Date, then Dakota and Merger Corp or
USMX shall have the right (provided in each case that such person
or persons is not in material breach of its obligations under
this Agreement), exercisable at any time after such date by
notice in writing, to terminate this Agreement and its
obligations hereunder.

     (b)  In the event that, prior to the Termination Date, any
Party (the "Breaching Party") is in material breach of its or
their obligations under this Agreement (and such breach cannot
reasonably be expected to be cured by the Breaching Party prior
to the Termination Date, or the Breaching Party is not taking
reasonable efforts to cure such breach, and, in either event,
such breach is not waived), then, so long as any other Party (the
"Non-Breaching Party") entitled to the benefit of such
obligations is not in default of its or their obligations under
this Agreement, the Non-Breaching Party shall have the right to
terminate this Agreement (unless such breach is or has been cured
prior to the giving of such notice of termination).

     (c)  No termination of this Agreement, whether pursuant to
this Section or otherwise, shall terminate or impair any claim by
Dakota and Merger Corp against USMX, or by USMX against Dakota
and Merger Corp, based upon any breach by the other of its
obligations under this Agreement if such breach serves as the
principal reason for the failure of the conditions contained in
Article VIII, IX, or X to have been satisfied; subject to
Sections 10.11(c) and 11.3.

XI.3 Liquidated Damages.  If this Agreement is terminated
consistent with Section 11.2 for the following reasons:

     (a)  by Dakota, if the Board of Directors of USMX shall have
made any recommendation to the USMX stockholders against the
Merger or in support of a Competing Transaction, or if USMX shall
have entered into a Competing Transaction; or

     (b)  by USMX, if the Board of Directors of USMX determines
in good faith, after consultation with and receiving written
advice from its outside legal counsel (which advice need not be
an opinion), that it is required, by reason of the fiduciary
duties of the directors of USMX to the USMX stockholders under
applicable Law, to recommend to the USMX stockholders that they
vote against the Merger and approve instead a Competing
Transaction that the USMX Board of Directors, has determined in
good faith, after consultation with its outside financial
advisors, is financially more favorable to the USMX stockholders
than the Merger (including any adjustment to the terms and
conditions of the Merger proposed by Dakota in response to such
Competing Transaction, if any), is the subject of a firm written
offer from a third party that is capable of consummating such
Competing Transaction and is likely to be successful, taking into
account any adjustments proposed by Dakota and the conditions and
valid and binding character of such offer,

then USMX may pay to Dakota (by wire transfer of immediately
available funds) a fee (the "Termination Fee") of US$500,000
within thirty days after the delivery of the notice of
termination in exchange for cancellation of the option, dated
February 5, 1997, granted to Dakota  to purchase 810,000 USMX
Shares; provided that USMX shall not be permitted to make such
payment if at any time prior to the making of such payment,
Dakota shall have exercised such option and USMX shall have
issued to Dakota the USMX Shares issuable upon such exercise.

The obligations of USMX to pay the Termination Fee are in lieu of
any damages or any other payment which USMX might otherwise be
obligated to pay to Dakota as a result of any termination for
which payment is due hereunder.  USMX agrees that, in view of the
nature of the issues likely to arise in the event of such a
termination, it would be impracticable or extremely difficult to
fix the actual damages resulting from such termination and
proving actual damages, causation and foreseeability in the case
of such termination would be costly, inconvenient and difficult.
In requiring USMX to pay the Termination Fee as set forth herein,
it is in the intent of the parties to provide, as of the date
hereof, for a liquidated amount of damages to be paid by USMX to
Dakota.  Such liquidated amount shall be deemed full and adequate
damages for such termination and is not intended by either party
to be a penalty.


ARTICLE XII
                        INDEMNIFICATION

XII.1     Indemnification by USMX.

     (a)  USMX shall indemnify the Dakota Group against, and hold

pursuant to Section 10.11(a)), such representations and
warranties shall not be deemed to have been breached for purposes

Dakota Group under Section 12.1(a)(1) exceed US$100,000 (the
"Basket") in the aggregate, at which time all Indemnifiable
Claims of the Dakota Group under Sections 12.1(a)(1) may be
asserted;

          (2)  if the matter which is the basis of such claim for
indemnification under Section 12.1(a)(1) is subject to a reserve
established on the books of the USMX Group as of the Closing
Date, except to the extent that any Indemnifiable Claims based on
such matters exceed such reserves;

          (3)  in any case, in an aggregate amount in excess of
US$3,500,000.

Except as otherwise set forth herein, claims for indemnification
in respect of breaches of covenants by USMX may be made at any

subject to the limitations contained in the preceding sentence.

XII.2     Indemnification by Dakota and Merger Corp.

     (a)  Dakota and Merger Corp shall indemnify the USMX Group
against, and hold the USMX Group harmless from, at all times

following:

          (1)  any breach of any of the representations or
warranties made by Dakota or Merger Corp in Article III; provided
that to the extent exceptions or qualifications to such
representations and warranties are disclosed to USMX in or on the
Exhibits hereto prior to the Closing Date (including as disclosed
pursuant to Section 10.11(a)), such representations and
warranties shall not be deemed to have been breached for purposes
of these indemnification provisions;

          (2)  any breach of the covenants made by Dakota or
Merger Corp in or pursuant to this Agreement, including
Articles VI and VII.

     (b)  The USMX Group shall not be entitled to assert any
claim for indemnification in respect of a breach of any
representation and warranty under Section 12.2(a)(1):

          (1)  until such time as all Indemnifiable Claims of the
Dakota Group under Section 12.2(a)(1) exceed the Basket in the
aggregate, at which time all Indemnifiable Claims of the USMX
Group under Sections 12.2(a)(1) may be asserted;

          (2)  if the matter which is the basis of such claim for
indemnification under Section 12.2(a)(1) is subject to a reserve
established on the books of the Dakota Group as of the Closing
Date, except to the extent that any Indemnifiable Claims based on
such matters exceed such reserves;

          (3)  in any case, in an aggregate amount in excess of
US$3,500,000.

Except as otherwise set forth herein, claims for indemnification
in respect of breaches of covenants by Dakota or Merger Corp may
be made at any time and from time to time after the date hereof
and shall not be subject to the limitations contained in the
preceding sentence.

XII.3     Assertion of Claims; Etc.

     (a)  If a party entitled to be indemnified pursuant to this
Agreement (an "Indemnitee") receives notice of the assertion by a
third party of any claim or of the commencement by any such
person of any action or proceeding (a "Third-Party Claim") with
respect to which another Party (an "Indemnifying Party") is
obligated to provide indemnification, the Indemnitee shall give
the Indemnifying Party prompt notice thereof after becoming aware
of such Third-Party Claim in reasonable detail and shall indicate
the amount (estimated if necessary) of the Indemnifiable Claim
that has been or may be sustained by the Indemnitee.  The receipt
of such notice shall be a condition precedent to any Liability of
the Indemnifying Party for any Third-Party Claim under the
provisions for indemnification contained in this Agreement;
provided, however, that the rights of the Indemnitee to be
indemnified or compensated hereunder in respect of any Third-
Party Claim shall only be affected by its failure to give prompt
notice to the Indemnifying Party of such Third-Party Claim if and
to the extent that such failure prejudices that Indemnifying
Party in the defense of such Third-Party Claim.

     (b)  If the Indemnifying Party elects to compromise or
defend such Third-Party Claim, it shall within thirty days notify
the Indemnitee of its intent to do so, it shall consult with the
Indemnitee and keep the Indemnitee fully informed as to matters
concerning such Third-Party Claim during the course of such
compromise or defense and the Indemnitee shall cooperate, at the
expense (out-of-pocket expenses only) of the Indemnifying Party,
in the compromise of, or defense against, such Third-Party Claim.

     (c)  If the Indemnifying Party elects not to compromise or
defend against the Third-Party Claim, or fails to notify the
Indemnitee of its election as herein provided or fails to
diligently defend any such Third-Party Claim, the Indemnitee may
pay (without prejudice of any of its rights as against the
Indemnifying Party), compromise or defend such Third-Party Claim.
The Indemnifying Party shall give the Indemnitee thirty days
notice of its intent to cease defending the Indemnitee with
respect to such Third-Party Claim and the Indemnitee shall be
fully indemnified hereunder for any additional damages suffered
by the Indemnitee if the cessation of such defense prejudices the
Indemnitee in the continuing defense or compromise of such Third-
Party Claim; provided, that upon assuming such responsibility the
Indemnitee shall use its best efforts to diligently defend or
attempt to compromise such Third-Party Claim.

     (d)  Notwithstanding the foregoing, neither the Indemnifying
Party nor the Indemnitee may settle or compromise any claim over
the objection of the other, provided, however, that consent to
settlement or compromise shall not be unreasonably withheld.

     (e)  The Indemnitee and the Indemnifying Party may each
participate, at its own expense, in the defense of such Third-
Party Claim.

     (f)  Any Indemnifiable Claim which does not result from a
Third-Party Claim shall be asserted by written notice given by
the party claiming indemnity to the party from which indemnity is
claimed.

     (g)  To the extent an Indemnifiable Claim may be covered by
insurance carriers under applicable insurance policies covering
such Indemnifiable Claim, the Indemnitee shall use its best
efforts to seek recovery in good faith for such Indemnifiable
Claim from such insurers.  Notwithstanding the foregoing, the
Indemnitee shall not be obligated to exhaust its remedies against
such insurance carriers in the event such carriers fail to accept
responsibility for such Indemnifiable Claim and the Indemnitee
shall be able to fully assert its rights of indemnification
against the Indemnifying Party hereunder; provided, that in such
event the Indemnitee shall assign its right of recovery with
respect to such Indemnifiable Claim against such insurance
carrier to the Indemnifying Party.  Any Indemnifiable Claim
hereunder shall be reduced by the amounts actually recovered by
the Indemnitee from its insurance carriers and any amounts
recovered by the Indemnitee subsequent to the payment by the
Indemnitor with respect to the same claim shall be remitted to
the Indemnitor; provided that such remittance shall not exceed
the amount of such indemnification payment by the Indemnitor.

XII.4     Survival of Representations, Warranties and Covenants.

     (a)  No claim for indemnification under the representations
and warranties contained in Article II and Article III shall be
made following April 30, 1998.

     (b)  The expiration of any representation and warranty shall
not affect any claim timely and validly made prior to the date of
such expiration.

     (c)  Except as otherwise expressly set forth herein, all
covenants and agreements of USMX, Dakota, and Merger Corp
contained in this Agreement shall survive the Closing hereunder,
without limitation.  However, any claim by USMX, Dakota, or
Merger Corp against the other based on a breach of any covenant
of the other required to be performed on or prior to the Closing
Date ("Pre-Closing Covenants") shall not survive the Closing and
shall be deemed to have been waived by the Party for whose
benefit such covenant exists; unless the Party who has made such
Pre-Closing Covenant has taken actions to intentionally conceal
the existence of such breach from the Party for whose benefit
such Pre-Closing Covenant exists, but provided that the Party for
whose benefit such Pre-Closing Covenant exists has suffered a

in the name of Dakota, at its address sert forth above, a
definitive certificate or certificates registered in the

such delivery or sending of such notice and notwithstanding
that such notice may not have been received by USMX, the
Option shall forthwith expire and terminate as to such of
the Optioned Shares in respect of which the Option has not
then been exercised.

5.   Nothing herein contained or done pursuant hereto shall
obligate Dakota to purchase and/or pay for, or USMX to
issue, any Optioned Shares, except those Optioned Shares in
respect of which Dakota shall have exercised its option to
purchase hereunder in the manner hereinbefore provided.

6.   In the event of any subdivision or change of the Shares
at any time prior to the Expiry Time into a greater number
of Shares, USMX shall deliver in connection with any issue
of Optioned Shares occurring after the record date of the
subdivision or change such additional number of Shares as
would have resulted from such subdivision or change if such
issue of Optioned Shares had been made prior to the record
date of such subdivision or change.  In the event of any
consolidation or change of the Shares at any time prior to
the Expiry Time into a lesser number of Shares, the number
of Shares to be delivered by USMX on any exercise thereafter
of the Option shall be reduced to such number of Shares as
would have resulted from such consolidation or change if
such exercise of the Option had been made prior to the
record date of such consolidation or change.

7.   If USMX shall at any time prior to the Expiry Time pay
any dividend or make any distribution or issuance, whether
or not payable in cash, property or other assets or in
shares or other securities of USMX, or make any payment by
way of return of capital, Dakota shall be entitled to
receive upon any exercise thereafter of the Option (in
addition to the number of Optioned Shares that Dakota
otherwise would have been entitled to receive on the
exercise of the Option) such cash, property or other assets
or such additional number of shares or other securities of
USMX or such capital payment as would have been payable on
the Shares that would have been issuable on such exercise of
the Option if they had been outstanding on record date for
payment of such dividend or such issuance, distribution or
capital payment, and USMX covenants and agrees that in the
event of any such payment of any dividend or issuance or
distribution payable in any shares or other securities of
USMX, it will reserve and set asisde a sufficient number of
shares or other securities of the appropriate class in which
any such dividend, issuance or distribution shall be payable
to enable it to fulfil its obligations hereunder.

8.   USMX covenants that it has duly reserved, set aside and
allotted the Optioned Shares to and in favour of Dakota, its
successors and assigns, and that upon the exercise of the
Option in accordance with the terms hereof and payment of
the Exercise Price, the Optioned Shares in respect of which
Dakota shall have duly taken up and paid for hereunder shall
be duly issued and outstanding as fully paid and non-
asessable.

9.   Time shall be of the essence of this agreement.

10.  USMX acknowledges that Dakota will have no adequate
remedy at law if USMX fails to perform any of its
obligations under this agreement.  In such event, USMX
agrees that Dakota shall have the right, in addition to any
other rights it may have, to specific performance of this
agreement and that it will not take any action to impede
Dakota's efforts to enforce such right of specific
performance.

11.  USMX and Dakota severally convenant and agree to use
their respective reasonable best efforts to comply with,
satisfy and fulfil promptly any contions and requirements
imposed by or arising out of legal, regulatory, stock
exchange or administrative requirements applicable to the
rant of the Option hereunder, the issue of Optioned Shares
on the exercise of the Option and to lising and posting for
trading of Optioned shares issued on the exe4cise of the
Option on the TSE and on such other stock exchanges or
through such over-the-counter or other organized markets on
or through which the Shares may be listed or traded, and to
co-operate with each other concerning such matters.

12.  Dakota represents and warrants to USMX, as a continuing
representation and warranty, which shall be true and correct
on the date hereof and on each date that Dakota exercises
the Option as if made and given on and as of each such date,
that Dakota is acquiring the Option and will acquire
Optioned Shares pruchased by it upon any exercise of the
Option as principal.  Dakota acknowledtes that (i) the
Option has not been and the Optioned Shares will not be
registered under the United States Securities Act of 1933
(the "1933 Act"), as amended, or under any state securities
laws and therefore the Optioned Shares cannot be sold
without registration under the 1933 Act and the securities
laws of all applicable states in the United States unless an
exemption from registration is available, and (ii) Dakota is
an "accredited investor" as that term is defined under
Regulation D of the 1933 Act.

13.  This agreement shall enure to the benefit of and be
binding upon the successors and assigns of the parties
hereto.  All rights granted hereunder to Dakota are fully
assignable.

14.  This agreement shall be governed by and construed in
accordance with the laws of the State of Colorado.

15.  This agreement may be executed by the parties in one or
more counterparts and, if so executed and delivered, either
in original or facsimile form, such counterparts shall
together constitute a single instrument.

     IN WITNESS WHEREOF the parties hereto have executed
these presents as of the day and year first above written.
