Leader will also grant to Kores the option to  acquire,  on or before the second
anniversary, 500,000 common shares of Leader at a price of $1.00 per share.

The  Effective  Date  will  occur  when  certain  conditions  precedent  are met
including  the receipt by Kores of approval from the Korean  government  and the
Korean  central  bank,  and the receipt by Leader of  approval  from the Alberta
Stock Exchange.

2. Vesting

     (a)  If Kores  fails to either make the  initial  $300,000  payment or fund
          expenditures  of $1,000,000 on or before the first  anniversary of the
          Joint Venture Agreement, then the Agreement will terminate, Kores will
          earn  no   interest,   and  neither   party  shall  have  any  further
          obligations.

     (b)  If on or after  the first  anniversary  date  Kores  fails to make any
          payment required or fails to fund the  expenditures  prior to the next
          anniversary  date,  then Kores will be deemed to have  terminated  its
          earn-in option and will retain only that interest which is relevant to
          the cumulative amount it has spent as described above.

3. Joint Venture

     (a)  A Joint Venture will be formed with Leader  contributing its interests
          in the  Property.  The Joint  Venture will be governed by a management
          committee  on which  Kores will have the  controlling  vote during the
          earn-in  period.  Thereafter,  voting  will  be in  proportion  to the
          parties' participating interests.

     (b)  After the earn-in period,  a standard  dilution  formula will apply to
          either  party who  elects  not to  contribute  its  pro-rata  share of
          expenditures in the Joint Venture.

     (c)  If either  party's  interest  falls to 15% then its  interest  will be
          converted to a 1% Net Smelter Return Royalty (NSR) and thereafter such
          party will have no further  rights or interest in the Property  except
          for the NSR.

          The non-reduced party will have the  right  to  purchase  the  NSR for
          $1,000,000.

     (d)  If either party having at least a 25% interest declines to participate
          in the development of a mineral deposit  recommended for  development,
          then its  interest  will  convert  to a 25%  carried  interest  in the
          Property  which will entitle it to receive 25% of  production  (net of
          operating cost) after exploitation

<PAGE>


          begins,  subject  to the contributing parties first recovering 200% of
          the incurred development costs.

     (e)  Within 30 days after the start of  commercial  production,  Kores will
          pay to Leader a completion bonus of $300,000.

4. Operatorship

     (a)  Leader will be the  Operator  during the earn-in  period.  Leader will
          resign  as  Operator  in favour  of Kores at Kores  request  after the
          second anniversary of the Joint Venture Agreement.

     (b)  Leader will provide office space and general  office support  services
          for up to 2 Kores  representatives  at no cost to  Kores  (except  for
          telephone,  facsimile,  and all other out of  pocket  expenses)  for a
          period  of 2  years  from  the  date  of  signing  the  Joint  Venture
          Agreement.

     (c)  Kores may assign up to two qualified  representatives  to perform work
          for the Operator  and shall be entitled to record  $25,000 per quarter
          as exploration expenditures for these personnel.

5. Records

Leader agrees to make available to Kores all pertinent  records and  exploration
work  pertaining  to the Property  upon signing the  contemplated  Joint Venture
Agreement.

6. Pre-Emptive Rights

Each of the parties  will have a  pre-emptive  right to purchase any interest of
the other party that the other party wishes to sell.

7. Area of Mutual Interest

If  either  Kores  or  Leader  acquires  any  properties  or lands  for  mineral
exploration  within 50 kilometers of the Property  boundary,  at the election of
the other party such property or lands shall become part of the Property subject
to the Joint Venture Agreement.

8. Joint Venture Agreement

The parties will diligently prepare a formal Joint Venture Agreement by November
15, 1999.  The Agreement will supercede  this  Memorandum of  Understanding  and
fully describe the Joint Venture relationship between Kores and Leader.

          (ii) any such  removal or remedial  action  shall be  undertaken  in a
               manner so as to minimize any impact on Leader's  operation on the
               Property;

     (b)  it will at all times retain any and all  liabilities  arising from the
          handling,   treatment,   storage,   transportation   or   disposal  of
          environmental  or  similar  contaminants  on or near the  Property  by
          Leader or by any of Leader's contractors or agents;

     (c)  it will, during the currency of the Option, keep the Property free and
          clear of all liens,  charges and  encumbrances,  save and except those
          arising from Joint Venture activities on the Property; and

     (d)  in the event of an adverse claim or claims (i) respecting the Property
          which does not arise from Kores'  activities on the Property,  or (ii)
          respecting  defects  of  title  affecting  all  or a  portion  of  the
          Property,  Leader shall, all at its sole expense, take immediate steps
          to defend against any such claim or claims or to cure any such default
          of title until such adverse  claim or claims is or are  judicially  or
          otherwise  fully settled and  determined or such defects are otherwise
          cured, and Kores

          plus  interest  at the Prime  Rate plus 3% from the date the Costs are
          incurred,  and until reimbursed (and without limitation as to exercise
          of other remedies) Kores may recover the Costs of such cure, including
          legal  fees and court  costs,  from  amounts  otherwise  due to Leader
          hereunder.

limitation, lawyer's fees and disbursements).

Report on Expenditures

3.6

     (1)  While the  Option  remains  outstanding  and  Leader is the  Operator,
          within 60 days following each Anniversary Date Leader shall deliver to
          Kores a  statement  showing  in  reasonable  detail  the  Expenditures
          incurred by Leader for the 12 month period  ending on the  Anniversary
          Date.  Kores  shall  have 90 days  from  the time of  receipt  of such
          statement  to  question  the  accuracy  thereof  by notice to  Leader,
          failing  which  such  statement  shall be  deemed  to be  correct  and
          unimpeachable thereafter.

     (2)  If the statement  delivered pursuant to subparagraph (a) is questioned
          by Kores,

          (a)  Kores  shall  have 12  months  from the time of  delivery  of the

               Venture Account as compared to the amount of Expenditures  stated
               to have been incurred and paid out of such account by Leader,  or
               that cost and expenses that do not qualify as  Expenditures  have
               been  paid out of funds  from the  Joint  Venture  Account,  then
               Leader will  restore to the Joint  Venture  Account the amount of
               such  deficiency or payment within 30 days  following  receipt of
               notice of such audited results; and

          (d)  the  costs of the  audit  shall be borne by  Leader  if  Leader's
               statement understated or overstated  Expenditures by more than 3%
               and otherwise shall be borne by Kores.

Payments to Leader

Dominion Bank in Calgary (Bank no. 004,  Branch no.  80609),  or such other bank
account in Canada as Leader  may  specify at least 15 days prior to the due date
for any payment.

price of $1.00 per share.  Kores may  exercise  the share option at any time and
from  time  to time  during  its  currency  with  respect  to some or all of the
optioned  shares.  To exercise the share option Kores must give notice to Leader
specifying  the number of shares in  respect of which the share  option is being
exercised,  accompanied  by full payment (in cash or by  certified  cheque or by
electronic  funds transfer) in the amount of the purchase price for such shares.

obligation assumed by it hereunder but, subject to Article 14:

     (a)  each  Participant  shall be at liberty to engage in any other business

          nature  similar  to  the  business  or  activity   undertaken  by  the
          Participants hereunder;

     (c)  the  legal   doctrines  of   "corporate   opportunity"   or  "business
          opportunity"  sometimes  applied to persons  occupying a  relationship
          similar to that of the  Participants  shall not apply with  respect to
          participation by any Participant in any business activity or endeavour
          outside  the  Joint  Venture,  and,  without  implied  limitation,   a
          Participant  shall not be accountable to the others for  participation
          in any such business  activity or endeavour  outside the Joint Venture
          which  is  in  direct   competition  with  the  business  or  activity
          undertaken by the Joint Venture; and

or  liabilities  on  behalf  of  the  other  Participant   except  such  as  are
specifically  authorized  pursuant to and in  accordance  with the terms of this

and its officers,  employees  and agents,  harmless from and against any and all
losses, claims, damages and liabilities arising out of any act or any assumption
of any  obligations by it done or undertaken on behalf of the other  Participant
other than as provided herein.

Bankruptcy of a Participant

4.8 If a  Participant  (a  "bankrupt  Participant")  concurs  in or  suffers  an
assignment for the benefit of its creditors,  the  appointment of a receiver for
all or substantially  all of its assets,  the filing of a petition in bankruptcy
or for  reorganization  or  protection  from  creditors  pursuant to  applicable
legislation,  or if it is otherwise  adjudicated bankrupt or insolvent,  with or
without its consent (an "event of bankruptcy"), then:

     (a)  if the event of  bankruptcy  occurs prior to the  commencement  of any
          Production  Program,  the bankrupt  Participant will be deemed to have
          withdrawn from this  Agreement and its Interest will be  automatically
          converted to the Net Smelter  Return  Royalty as of the  occurrence of
          such  event  and  thereafter  the  bankrupt  Participant  will have no
          further  rights or  interest  in  respect  of the Assets or under this
          Agreement, save and except the right to receive its Net Smelter Return
          Royalty; or

     (b)  if the event of bankruptcy occurs after a Production Program but prior
          to Commercial  Production,  the bankrupt Participant will be deemed to
          have offered to sell its Interest to the other  Participants  pro rata
          according  to  their  relative  Interests,  at a  price  equal  to the
          cumulative amount that the bankrupt  Participant has paid for its Cost
          Share to the date of such event which,  for these purposes,  is deemed
          to be the aggregate of its base costs as contemplated  under paragraph
          5.2 and all of its contributions  towards  Expenditures and Production
          Program  Costs  subsequent to the Final Vesting Date plus, in the case
          of Kores, all payments made to Leader under paragraph 3.3; or

     (c)  if the event of  bankruptcy  occurs after  Commercial  Production  has
          commenced,  the bankrupt Participant will be deemed to have offered to
          sell its  Interest to the other  Participants  pro rata  according  to
          their relative Interests, at a price equal to the fair market value of
          such Interest, discounted by 20%.

                           INTERESTS OF PARTICIPANTS

Interests

5.1 On the  Effective  Date,  Leader shall have an undivided  100%  Interest and
Kores shall have 0% Interest.  On the Final Vesting  Date,  Kores shall have the
Interest that it has earned  pursuant to paragraph 3.3 and Leader shall have the
Interest  equal to the  percentage  which when added to Kores'  Interest  totals
100%.  Thereafter,  each  Participant  shall have such Interest as is determined
from time to time in accordance with the provisions of this Agreement.

Dilution Formula

5.2 After the Final Vesting Date the  respective  Interests of the  Participants
shall be determined from time to time as being equal to the product  obtained by
multiplying  100% by a fraction of which the  numerator is the  aggregate of (i)
$5,200,000  (the "Leader base costs"),  or (ii) the  cumulative  amount spent by
Kores according to the table set forth in paragraph 3.3 for Kores to have earned
the  Interest  which it  acquired  on the Final  Vesting  Date (the  "Kores base
cost"),  plus  (iii)  the  amount  of  the  relevant  Participant's   subsequent
contributions to Expenditures  and Production  Program Costs and the denominator
is the  aggregate of the Leader base costs,  the Kores base costs and the amount
of  all  contributions  to  Expenditures  and  Production   Program  Costs  made
subsequent to the Final Vesting Date by all Participants.

Multiple Participants

5.3 If there are more than two  Participants  the dilution  formula in paragraph
5.2 will be applied mutatis mutandis as required, provided that an assignment by
a Participant of all or part of its Interest will carry with it an assignment of
that  proportion  of  the  aggregate  of  the  Participant's   base  costs,  its
Expenditures  and its Production  Program Costs to the time of assignment  which
equals the percentage of the Participant's Interest which is being assigned.

Dilution and Conversion to a Net Smelter Return Royalty

5.4 After the Final Vesting Date the  respective  Interests of the  Participants
shall not change so long as they each contribute their respective Cost Shares of
every  Program  as set out in  Article 7 and  Production  Program  as set out in
Article 8. Subject to  paragraph  8.2, at any time and from time to time after a
Participant  elects or is deemed to have elected not to  contribute to a Program
or Production Program,  its respective Interest shall be reduced, and each other
Participant's  Interest shall be proportionately  increased,  in accordance with
the formula set out in paragraph 5.2. If, as a result of such  calculation,  the
Interest of a  Participant  is reduced to or below 15%,  its  Interest  shall be
deemed to be converted to the Net Smelter  Return  Royalty and  thereafter  such
party shall have no further rights or Interest in respect of the Assets or under
this  Agreement,  save and  except  for the Net  Smelter  Return  Royalty.  If a
Participant  assigns part of its Interest the  percentage  Interest to which the
Participant's and the assignee's  Interest must be diluted prior to its Interest
being  converted to the Net Smelter  Return Royalty shall remain at 15% for each
of them and the Net Smelter Return Royalty to which the assigning  Participant's
or the  assignee's  Interest  will be converted  shall be pro rata  according to
their respective Interests.

          normal  business hours,  and without undue  disruption of the work and
          operations of the Operator hereunder;

     (h)  to obtain and maintain,  or cause any contractor  engaged hereunder to
          obtain and maintain, during any period in which active work is carried
          out hereunder,  such insurance as the Operator reasonably considers to

its  duties  and  responsibilities  under this  Agreement,  then the  Management
Committee shall give to the Operator written notice setting forth particulars of
the Operator's default.  The Operator will, as soon as possible after receipt of
such notice commence to remedy the default.  Failure of the Operator promptly to
commence to remedy the default or to cure the default (and thereafter to proceed

On any  termination of the Operator's  appointment  hereunder,  a meeting of the
Management  Committee  shall  forthwith be convened to appoint another party who
consents to act as Operator, and determine its terms of engagement.  An Operator
in default  hereunder  shall not be  entitled to vote as a  Participant  for the

the  successor  Operator  custody  of all  Assets  and  any  books  and  records

accordance with their Interests.  Each Participant  shall be responsible for its
Cost  Share  of  all  costs  and  expenses   related  to  such  termination  and
liquidation.  If the Operator has voluntarily resigned, then the party which was
the Operator  may, if it consents to act,  continue to act as Operator to effect
such  termination and liquidation and it shall have a lien on the  Participants'
respective  Interests in the Assets and any  proceeds  therefrom as security for
their respective Cost Shares of all costs,  expenses and other liabilities owing
in respect of or as of the date of such termination.

6.7 Subject to paragraph  6.8,  each  Participant  shall  indemnify and save the
Operator harmless from and against any loss, liability,  claim, demand,  damage,
expense,  injury and death  (including,  without  limiting the generality of the
foregoing,  legal fees)  resulting from any acts or omissions of the Operator or
its officers, employees or agents.

Leader and Kores and for the purposes of the Joint Venture:

     (a)  from the Effective Date for a period of two years, Leader will provide
          to Kores at no charge office space and use of general office equipment

Expenditures to Be Incurred Under Programs

7.1 Expenditures  shall only be incurred under and pursuant to Programs prepared
by the  Operator and  approved by the  Management  Committee as provided in this
Article.  Any  Feasibility  Report  shall be  prepared  pursuant  to a  separate
Program.

Election To Participate in Programs

7.2 Within 30 days after the approval by the  Management  Committee of a Program
to be carried out after the Final Vesting Date, the Participants shall each give
written notice to the Operator  stating  whether or not they elect to contribute
their  respective Cost Shares of such Program.  Failure by a Participant to give
notice  pursuant to this paragraph  within such 30-day period shall be deemed to
be an election by that Participant not to contribute to such Program.

Effect of Election to Not Contribute

7.3 If a Participant (for the purposes hereof a "Non-Contributor")  elects or is
deemed to have elected not to contribute its Cost Share of a Program, each other
Participant  (for the  purposes  hereof a  "Contributor")  that has  elected  to
contribute  its Cost  Share of the  Program  may give  notice in  writing to the
Operator stating that it will contribute, in addition to its own Cost Share, the
Cost  Share of the Non-  Contributor.  If more than one  Participant  gives such
notice,  they  shall  contribute  pro  rata to  their  Interests  or as they may
otherwise  agree.  In such event,  subject to paragraph  7.4, the Operator  will
proceed with such Program and, on completion  of such Program,  the Interests of
the parties shall be adjusted in accordance  with paragraph 5.4;  provided that,
if such Program is  completed  to the extent of less than 80% of the  originally
estimated  Expenditures  thereunder,  the  Interests  of the parties will not be
adjusted  unless notice is first given to the  Non-Contributor  that the Program
was  abated,  together  with  notice of the  amount of the  actual  Expenditures
thereunder,  and the  Non-contributor  does  not,  within  20  days  thereafter,
reimburse  the  Contributor  or  Contributors  to the  extent of its Cost  Share
thereof  (being the amount which the respective  Contributor  elected to and did
contribute instead of the Non- Contributor), together with interest thereon from
the date contributed by the contributor,  at a per annum rate equal to the Prime
Rate  plus  2%.  If  the   Non-Contributor  so  reimburses  the  Contributor  or
Contributors  within such 20-day  period,  it shall be deemed to have elected to
contribute its Cost Share of such Program and the Interests of the  Participants
shall not be adjusted.  A  Participant  that elects or is deemed to have elected
not to contribute to a Program may,  subject to paragraph  5.4,  participate  in
future Programs.

Operator Not to Proceed Unless Program Is Fully Funded

7.4 After the Final  Vesting Date the Operator will not proceed with any Program
which is not fully  subscribed  except that the  Operator  shall at all times be
entitled to incur such expenditures as are necessary  pursuant to paragraph 6.12
or to maintain  the  Property in good  standing  and the  Participants  shall be
liable for their Cost Share thereof,  regardless of any election  hereunder.  If
the  Participants  fully subscribe to a Program,  the Operator will proceed with
such Program.

Obligation To Pay Expenditures and Overruns

7.5 An election by a  Participant  to  contribute  to a Program  shall make that
Participant liable to pay its respective share of Expenditures actually incurred
under or pursuant to the Program  including  Program  Overruns,  as  hereinafter
defined of up to but not exceeding 10%.

Procedures For Payment

7.6 After  having  elected to  contribute  to a Program  which  proceeds or if a
Participant  is  otherwise  obligated to pay its Cost Share of  Expenditures,  a
Participant  shall,  within  15 days  after  receipt  of a Cash  Call  from  the
Operator,  pay such  portion of its share of  Expenditures  as the Cash Call may
require.

Meeting Required to Approve Excess Program Overruns

7.7 If it appears to the Operator that  Expenditures will exceed those estimated
under a Program,  the Operator  shall  immediately  give  written  notice to the
Participants contributing to that Program outlining the nature and extent of the
additional costs and expenses (herein called "Program Overruns") and the reasons
therefore.  If Program  Overruns are  estimated to exceed by 10% those  approved
under the Program (herein called "Excess Program  Overruns"),  the notice of the
Operator shall contain a notice of a meeting of the Management Committee,  to be
held no sooner  than 5 Business  Days after the date of  delivery of the notice,
for the purpose of considering,  and if deemed  advisable,  approving the Excess
Program Overruns.  If the Excess Program Overruns are approved by the Management
Committee,  the Participants  contributing to that Program shall, within 15 days
after the receipt of a written  request from the Operator,  provide the Operator
with their Cost Share of such Excess  Program  Overruns.  If such Excess Program
Overruns are not approved by the  Management  Committee,  the Operator  shall be
responsible for them unless it curtails or abandons such Program.

Effect of Default in Paying Expenditures

7.8 If a  Participant  at any time fails to pay its Cost  Share of  Expenditures
(including  Program  Overruns and approved Excess Program  Overruns) as required
under  paragraphs  7.4, 7.5 or 7.7, then the Operator may give written notice to
that  Participant  demanding  payment and, if that Participant has not paid such
amount,  together with  interest  thereon at Prime Rate plus 6% from the date on
which payment was due, within 15 days after receipt of such notice, the Interest
of that  Participant  shall be deemed to be converted to the Net Smelter  Return
Royalty  and  thereafter  that party will have no further  rights or interest in
respect of the Assets or under this  Agreement,  save and except its Net Smelter
Return  Royalty.   Any  interest  paid  by  or  recovered  from  the  defaulting
Participant  shall be for the account of the  Participants  that provided  funds
required of them as a result of the default, pro rata to their contributions, or
otherwise shall be paid to the  Participants  not in default,  pro rata to their
Interests. If, upon the default of a Participant pursuant to this paragraph 7.8,
the other Participant or Participants, if more than one, do not thereafter elect
to contribute  pro rata to their  Interests or as otherwise  agreed by them, the
defaulting Participant's Cost Share of the remaining Expenditures,  the Operator
shall have the right to curtail or abandon the Program.

Program For a Feasibility Report

7.9  Any of the  Participants  holding  in the  aggregate  not  less  than a 25%
Interest,  shall  be  entitled  to  request,  by  written  notice  to the  other
Participants for consideration at any meeting of the Management Committee,  that
the Operator propose a Program for the preparation of a Feasibility  Report.  If
the Management  Committee fails to approve such Program within 60 days following
receipt  of such  notice,  then the  Participant  giving  such  notice  shall be
entitled to prepare a Feasibility Report at its own expense.  The preparation of
a Feasibility Report by a Participant or Participants under this paragraph shall
not affect the  rights of the  Operator  to  continue  to propose  and carry out
Programs as otherwise set forth in this Article.

Participant's Feasibility Report

7.10 In the event that a feasibility report prepared by one or more Participants
does not qualify as a Feasibility Report hereunder, then no further action shall
be taken in respect thereof and any expenses  incurred by the Participant  which
prepared such  feasibility  report shall be for its own account and shall not be
considered Expenditures made under this Agreement.

Favourable Feasibility Report

7.11 In the event  that a  feasibility  report  prepared  by the  Operator  as a
Program or by one or more Participants  pursuant to paragraph 7.9 qualifies as a
Feasibility  Report  hereunder,   then  it  shall  be  delivered  to  the  other
Participants and the provisions of Article 8 shall apply.

Provision of Security

7.12 To the  extent  that  security  (whether  in the form of  cash,  negotiable
securities, letters of guarantee, irrevocable letters of credit or otherwise) is
required  to be  posted  with  or in  favour  of  any  regulatory  authority  or
government in connection with Programs,  a Production Program or Operating Plan,
each of the Participants will lodge security,  in such form as may be acceptable
to the particular  authority,  in an amount proportionate to its Interest at the
time and to the total amount of security then required by the authority,  and if
the security  will expire at a  particular  time a  Participant  will replace or
renew its security before that time if required by the authority.

Delivery of Proposed Production Program

8.1 At any time after  delivery  to the  Participants  of a  Feasibility  Report
pursuant to  paragraph  7.11,  the  Operator  may,  and shall within 120 days of
receipt by it from  Participants  holding in the  aggregate  not less than a 25%
Interest  of a  request  in  writing  to do  so,  prepare  and  deliver  to  the
Participants  a  Production  Program  which  shall be based on such  Feasibility
Report. The preparation of the Production Program shall be deemed to be pursuant
to a Program  in which  each  Participant  has  elected to pay its Cost Share of
Expenditures  incurred  thereunder.  Within  180  days  of the  receipt  by each
Participant  from the Operator of a Production  Program,  each such  Participant
shall  give  written  notice  to the  Operator  stating  whether  it  elects  to
contribute its Cost Share of the Production Program. Failure to

give such notice within such 180-day period shall be deemed to be an election by
such Participant not to contribute to the Production Program.

Production Program to Proceed

8.2  (1) If all of the  Participants  elect to contribute  their respective Cost
Shares of a Production  Program,  then such Production Program will be deemed to
have been  adopted by the Joint  Venture  and,  subject to  paragraph  8.3,  the
Operator will proceed with such Production Program.

     (2) If  Participants  whose Interests total 75% or more elect to contribute
their  respective  Cost Shares of a  Production  Program,  then such  Production
Program  will be deemed to have been  adopted by the Joint  Venture.  Subject to
paragraph 8.3, the Operator will forthwith proceed with such Production  Program
and, on completion of such Production Program, the Interests of the Participants
shall be adjusted in accordance with paragraph 5.4.

     (3) If  Participants  whose  Interests  total 50% or more but less than 75%
elect to contribute their respective Cost Shares of a Production  Program,  then
such  Production  Program  will be  deemed  to have  been  adopted  by the Joint
Venture. Subject to paragraph 8.3, the Operator will forthwith proceed with such
Production  Program and the Interest of any Participant  (the  "non-contributing
Participant")  who  has  elected  not to  contribute  its  Cost  Share  of  such
Production  Program, if such Interest is greater than 25%, will automatically be
reduced to the Carried Interest  effective upon the election of the contributing
Participants.  Thereafter, the contributing Participants will be obliged to bear
and pay pro rata the 25% Cost  Share of the  non-contributing  Participant,  but
following the Completion  Date will have the right to receive pro rata according
to their relative  Interests the 25% share of Mineral Products to which the non-
contributing Participant would be entitled, until such time as each has received
an amount of Mineral Products, valued in accordance with paragraph 11.2, at 200%
of the  additional  Cost  Share  borne  by the  contributing  Participant.  If a
Participant  assigns part of its Interest then the Carried  Interest to which it
and its assignee may become  entitled  will be in the same  proportion  as their
respective Interests after such assignment. The Interest of any non-contributing
Participant  who has elected not to contribute  its Cost Share  pursuant to this
paragraph  8.2(3),  if such  Interest  is 25% or  less,  shall  be  adjusted  in
accordance  with  paragraph  5.4,  along with the Interests of the  contributing
Participants, upon completion of the Production Program.

     (4) If  Participants  whose  Interests  total  more  than 50%  elect not to
contribute  their  respective  Cost Shares of a  Production  Program,  then such
Production Program will be deemed to have been withdrawn.

     (5) If the  Feasibility  Report on which a Production  Program is based was
prepared by one or more Participants pursuant to paragraph 7.9, then 125% of the
costs  thereof as  incurred by such  Participants  and as  supported  by written
evidence  shall be deemed to be  Expenditures  and,  within 15 days  following a
written demand therefor  (together with such evidence),  the other  Participants
shall reimburse the Participant or Participants  that prepared such  Feasibility
Report to the  extent of their  respective  Cost  Shares  thereof.  Failure by a
Participant  to reimburse its Cost Share thereof shall result in dilution of its
Interest  under  paragraph  5.4,  with the  non-reimbursed  portion as aforesaid
deemed to have  been  contributed  (in  addition  to its own Cost  Share) by the
Participant  that  prepared  the  Feasibility  Report,  or,  if  more  than  one
Participant,  such  shall be  apportioned  among them in  accordance  with their
respective contributions to the Costs of preparing the Feasibility Report.

     (6)  Production  Program Costs shall only be incurred under and pursuant to
Production Programs deemed to be adopted pursuant to this paragraph 8.2.

Obligation to Pay Production Program Costs and Overruns

8.3 An election to contribute  to a Production  Program shall make a Participant
liable to pay its Cost Share of all of the  Production  Program  Costs  actually
incurred  under or pursuant to such  Production  Program,  including  Production
Program  Overruns (as  hereinafter  defined) of up to but not exceeding 10%. The
Operator need not proceed with a Production  Program until each  Participant has
delivered proof,  satisfactory to the Operator,  of the Participant's ability to
pay its Cost Share of such  Production  Program  including,  if  required by the
Operator from any Participant  whose net worth  (according to its last available
balance  sheet) is less than 300% of its Cost  Share of  anticipated  Production
Program Costs, letters of credit or other reasonable  guarantees of availability
of funds.

Procedures For Payment

8.4 After having elected to contribute to a Production  Program which  proceeds,
each Participant  shall,  within 15 days after a Cash Call by the Operator,  pay
such portion of its Cost Share of the Production  Program Costs as the Cash Call
may require,  and provide such  security or  additional  security as may then be
required as contemplated in paragraph 7.12.

Meeting Required To Approve Excess Production Program Cost Overruns

8.5 If it appears to the  Operator  that  Production  Program  Costs will exceed
those estimated  under the Production  Program,  the Operator shall  immediately
give written notice to the  Participants  outlining the nature and extent of the
additional costs and expenses (herein called "Production  Program Overruns") and
the reasons therefor.  If Production Program Overruns are estimated to exceed by
10%  those  estimated  under  the  Production  Program  (herein  called  "Excess
Production Program Overruns"), the notice of the Operator shall contain a notice
of a meeting of the Management  Committee,  to be held no sooner than 5 Business
Days after the date of delivery of the notice,  for the purpose of  considering,
and if deemed advisable,  approving the Excess Production  Program Overruns.  If
the Excess Production Program Overruns are approved by the Management Committee,
each  Participant  shall,  within 15 days after the receipt of a written request
from the  Operator,  provide  the  Operator  with its Cost Share of such  Excess
Production Program Overruns.

Curtailment of Production Program

8.6 If Excess  Production  Program  Overruns are not approved by the  Management
Committee,  as provided in paragraph 8.5, the Operator shall be responsible  for
them but shall  have the right to  curtail or  abandon  the  Production  Program
unless a Participant that has approved such Excess  Production  Program Overruns
has advanced the amount of such Excess Production Program Overruns. On so doing,
such  Participant  shall be entitled to recover the amount of such  advance from
the sale of Mineral Products of the other Participant or Participants,  together
with  interest  thereon from the date  advanced at a per annum rate equal to the
Prime Rate plus 5%,  and the  provisions  of  paragraph  11.3  shall  apply with
respect thereto.

Effect of Default in Paying Production Program Costs

8.7 If a  Participant  at any time  fails to pay its  Cost  Share of  Production
Program Costs  (including  Production  Program  Overruns  and  approved  Excess
Production  Program  Overruns)  in  accordance  with  paragraph  8.4 or 8.5, the
Operator may give written notice to such Participant  demanding  payment and, if
such  Participant  has not paid such amount,  together with interest  thereon at
Prime Rate plus 6% from the date on which payment was due,  within 15 days after
receipt  of such  notice,  such  Participant  shall be deemed  to be in  default
hereunder and either, as the Management  Committee (excluding the Participant in
default)  may  determine,  (a) its Interest  shall be deemed  converted to a Net
Smelter Return Royalty,  or (b) its Interest shall be diluted in accordance with
paragraph 5.4 and, in addition, it shall be liable for all damages occasioned to
the other Participants by its default  hereunder,  unaffected by the dilution in
its Interest.  If the Management  Committee adopts alternative (a),  thereafter,
such defaulting  Participant shall have no further rights or interest in respect
of the Assets or under  this  Agreement,  save and  except for such Net  Smelter
Return Royalty,  and such conversion  shall otherwise not relieve the defaulting
Participant  of any  liability  or  obligation  incurred  up to the time of such
default and  conversion.  Any interest paid by or recovered  from the defaulting
Participant  shall be for the account of the  Participants  that provided  funds
required of them as a result of the default pro rata to their contributions,  or
otherwise shall be paid to the  Participants  not in default,  pro rata to their
Interest.

Operator's Right to Curtail Production Program Upon Default

8.8 If, upon the default of a Participant  pursuant to paragraph  8.7, the other
Participant  or  Participants,  if more than  one,  do not  thereafter  elect to
contribute  pro rata to their  Interests  or as  otherwise  agreed by them,  the
defaulting  Participant's Cost Share of remaining  Production Program Costs, the
Operator shall have the right to curtail or abandon the Production Program.

Completion Bonus

8.9 Within 30 days after the Completion  Date,  Kores will pay to Leader a bonus
of  $300,000  to reflect  the  achievement  of  Commercial  Production  from the
Property contributed by Leader to the Joint Venture.

                                OPERATING PLANS

Obligation to Pay Operating Costs and Overruns

9.1 Following the Completion Date, each  Participant  shall be liable to pay its
Cost Share of all Operating  Costs  incurred  under  approved  Operating  Plans,
including  Operating  Cost  Overruns (as  hereinafter  defined) of up to but not
exceeding  10%.  Operating  Costs shall only be incurred  under and  pursuant to
Operating  Plans  prepared  by the  Operator  and  approved  by  the  Management
Committee as provided in this Article.

Operating Plans

9.2 At least 90 days prior to the date the Operator  anticipates  the Completion
Date will occur,  the Operator will propose and deliver to the  Participants  an
Operating Plan for the first Operating Year.

Subsequently,  at least  90 days  before  the  commencement  of each  succeeding
Operating Year, the Operator shall propose an Operating Plan by delivery of such
to each  Participant  for such  succeeding  Operating  Year.  Within  30 days of
delivery of a proposed  Operating  Plan  hereunder,  a meeting of the Management
Committee shall be convened to review, amend (if deemed appropriate) and approve
same.

Excess Operating Cost Overruns

9.3 Except as herein  provided,  the Operator shall have the power and authority
to deviate from or make  modifications  to Operating Plans from time to time, in
accordance  with good  engineering  and mining  practices.  If it appears to the
Operator that  Operating  Costs will exceed those  estimated  under an Operating
Plan, the Operator  shall  immediately  give written notice to the  Participants
outlining  the nature and extent of the  additional  costs and expenses  (herein
called  "Operating Cost Overruns") and the reasons  therefor.  If Operating Cost
Overruns are estimated to exceed by 10% those estimated under the Operating Plan
(herein called "Excess  Operating  Cost  Overruns"),  the notice of the Operator
shall contain a notice of a meeting of the Management  Committee,  to be held no
sooner than 5 Business  Days after the date of delivery of the notice,  together
with a proposed  amendment to the Operating  Plan. The meeting of the Management
Committee shall be convened to review, amend (if deemed appropriate) and approve
same.  Excess  Operating Cost Overruns not approved by the Management  Committee
will be the responsibility of the Operator.

No Agreement on Operating Plan

9.4 If a proposed  Operating  Plan or  amendment  thereto is not approved by the
Management  Committee,  then  the  Operating  Plan  or  its  amendment  will  be
determined  by a special  arbitration  according to the  procedures  established
under article 16 and this paragraph 9.4. In such  arbitration,  each Participant
will be entitled to submit to the arbitrator its proposal for the Operating Plan
or amendment  thereto and the  arbitrator  will be entitled to choose from among
the submissions  received the Operating Plan or amendment  thereto which, in the
circumstances, provides the optimal return for the Participants over the life of
the mine  having  regard to the  nature of the  deposit,  the  condition  of the
Facilities and current and projected market conditions, but will not be entitled
to make any other award.  The Operating Plan or amendment  thereto chosen by the
arbitrator  will be deemed to be an  Operating  Plan or amended  Operating  Plan
approved by the Management Committee for the Operating Year in question.

Payment of Operating Costs

9.5 Following the  Completion  Date, a Participant  shall,  within 15 days after
receipt  of a Cash  Call from the  Operator,  pay such  portion  of its share of
Operating Costs (including Operating Cost Overruns and approved Excess Operating
Cost Overruns) as the Cash Call may require.

Effect of Default in Paying Operating Costs

9.6 If a Participant  fails to pay all or any part of its Cost Share pursuant to
paragraph 9.5, the other  Participant or Participants if more than one, shall be
entitled, pro rata to their Interests or as otherwise agreed by them, to pay all
or a portion of the  unpaid  Cost Share of the  defaulting  Participant.  If the
other  Participants pay such unpaid share, then they will be entitled to recover
the  amount  so paid  from the  sale of the  defaulting  Participant's  share of
Mineral Products,  together with interest thereon from the date so paid at a per
annum rate equal to the Prime Rate plus 6%,  and the  provisions  of  paragraphs
11.3 and 15.4 will apply.

Participant May Require Operations To Be Shut Down

9.7 Any Participant shall be entitled,  by notice in writing to the Operator and
the other  Participant,  to require that  Operation of the Property as a mine be
suspended if for a period of 6 consecutive months:

     (a)  such  Participant  can  demonstrate (as set forth in such notice) that
          its Cost Share of Operating  Costs has exceeded the proceeds  from the
          sale of its share of Mineral Products; and

     (b)  within 30 days after receipt of such notice, the other Participant has
          not  demonstrated  to the Operator  that the proceeds from the sale of
          its share of Mineral Products have equalled or exceeded its Cost Share
          of Operating Costs during such six month period.

If such notice is given to the Operator it shall  prepare an Operating  Plan for
placing  the mine on care and  maintenance  and shall  convene a meeting  of the
Management Committee to approve such Operating Plan.

Resumption of Operations

9.8 If at any time after the suspension of operations pursuant to paragraph 9.7,
the  Operator  determines  that the  mine can be  placed  back  into  Commercial
Production with the  Participants'  Cost Share of Operating Costs being not more
than 80% of the proceeds which they should realize on the sale of their share of
Mineral  Products,  the  Operator  shall  prepare  an  Operating  Plan  for  the
resumption of Operation of the Property as a mine and shall convene a meeting of
the Management Committee to approve such Operating Plan.

Committee  shall consist of a member or members  representing  each  Participant
whose  Interest is 25% or more  provided  that prior to the Final Vesting Date a

alternates)  are  present.  The  Management  Committee  shall decide all matters
coming before it at a meeting by the affirmative vote of a majority of the votes
entitled  to be  cast by  members  at the  meeting.  The  representative  of the
Operator shall act as Chair for each meeting of the Management Committee and, as
such,  shall have an  additional  or casting  vote in the case of an equality of
votes on any matter. Notwithstanding any other provision of this paragraph 10.6,

kind and  separately  dispose of its share (in  proportion  to its  Interest) of
Mineral Products.

Valuing Mineral Products

kind,  Mineral  Products  shall be valued  and  accounted  for as of the time of
delivery to or  settlement  with the  purchaser  or  purchasers  thereof,  after

limitation:

     (a)  all costs of storage and transportation, including insurance;

Right to Share of Production

11.3 If a  Participant  makes any payment on behalf of a defaulting  Participant
pursuant  to  paragraph  9.6, or if a  Participant  advances  Excess  Production
Program Overruns pursuant to paragraph 8.6, then such Participant shall have the
prior and first right to receive the share of Mineral Products of the defaulting
Participant or the Participant which did not advance Excess  Production  Program
Overruns,  as the case may be,  until  such  Participant  has  received  Mineral
Products  in kind of a value,  determined  under  paragraph  11.2,  equal to the
amount  advanced  together  with  interest  thereon  at the  rate  specified  in
paragraph 8.6 or 9.6, as the case may be.

11.4 The accounts and records of the paying or advancing  Participants  relating
to Mineral  Products  taken in kind or to the  calculation  of proceeds from the
sale  thereof as  contemplated  in paragraph  11.3 may, at the  direction of the
defaulting or non-advancing Participant,  be audited annually at the end of each
Operating Year. Any  adjustments  required by such audit shall be made forthwith
and a copy  of  the  audited  statements  shall  be  delivered  to the  relevant
Participants.  All such  accounts and records  shall be deemed to be correct and
accurate unless  questioned by a Participant  within 12 months following the end
of the Operating Year to which the accounts relate.  The Participants shall make
all  reasonable  efforts to conduct  audits in a manner,  which will result in a
minimum of inconvenience to the Participant subject to the audit.

Non-Arm's Length Sale of Product

11.5 If a Participant or an Affiliate of a Participant is a purchaser of Mineral
Products  hereunder,  and if the  value  of  such  Mineral  Products  is used to
determine any matter arising under this Article,  then the Participant  shall be

replaces  and  supersedes  all  prior  agreements,   memoranda,   correspondence
communications,  negotiations  and  representations,  whether  oral or  written,

Smelter  Return  Royalty  and  Schedule  2 may be made by the  Participants  and
without  the  execution  thereof by any party that  holds a Net  Smelter  Return

or  default  by any  other  party of any or all of its  obligations  under  this
Agreement will:

     (a)  be valid  unless it is in writing and stated to be a consent or waiver
          hereunder;

     (b)  be  relied  upon as a consent  or waiver to or of any other  breach or
          default of the same or any other obligation;

     (c)  constitute a general waiver under this Agreement; or

19.4 Except as otherwise  provided herein,  all payments to be made to any party
hereunder  may be made by cheque or draft  mailed or  delivered to such party at
its address for notice as provided  herein,  or for the account of such party at
such bank or banks in Canada as such  party may  designate  from time to time by
written notice.  Such bank or banks shall be deemed the agent of the designating
party for the purpose of receiving, collecting and receipting such payment.

Termination

19.5  (1) In  addition  to  provisions  for its  termination  elsewhere  in this
Agreement, the Joint Venture will terminate:

     (a)  when  there  are  only two  Participants,  upon  the  conversion  of a
          Participant's  Interest to the Net Smelter Return  Royalty,  or to the
          Carried  Interest as  contemplated in paragraph 8.2, or otherwise when
          there is only one Participant remaining;

     (b)  if the Participants have agreed to wind up the Joint Venture or it has
          been  terminated  pursuant to paragraph  6.6, then following the sale,
          abandonment or  liquidation of all of the Assets and the  distribution
          of the proceeds  therefrom and any other Joint Venture  funds,  net of
          any Joint Venture obligations and liabilities, to the Participants pro
          rata according to their  Interests,  but only if all  reclamation  and
          closure  obligations  of the Joint  Venture have been paid or provided
          for.

Upon any termination  which results from there being only one Participant,  such
Participant will continue to have and bear all of the  Participant's  rights and
obligations in relation to any Net Smelter Return  Royalty  (including,  without
limitation,  the purchase  option  described  in paragraph  5.6) and any Carried
Interest remaining at the time of such termination.

     (2) This Agreement will terminate upon the occurrence of the earliest of:

     (a)  the  Effective  Date or the first  Anniversary  Date,  as described in
          paragraph 3.4;

     (b)  the termination of the Joint Venture pursuant to paragraph 19.5(l)(b);

     (c)  after the Joint Venture has been  terminated  and only the Net Smelter
          Return  Royalty  remains,  upon the  exercise of the  purchase  option
          described in paragraph 5.6.

Joint Venture Agreement                     Leader Mining International Inc. and
                                                              Kores Canada Corp.


Default

19.6 Except for the  provisions  of this  Agreement  providing  for elections to
contribute and  contributions to Programs and Production  Programs and Operating
Costs, with which the Participants must strictly comply, and except as otherwise
provided in this Agreement,  if any Participant is in default of any requirement
herein  set  forth,  any  other  Participant  may  give  written  notice  to the
defaulting  Participant specifying the default. The defaulting Participant will,
as soon as possible after receipt of such notice commence to remedy the default.
Failure to  promptly  to  commence  to remedy the default or to cure the default
(and thereafter to proceed  continuously and diligently to complete all required
remedial  action) within the 30-day period after such notice will be grounds any
non-defaulting  Participant  to seek any remedy to which it may be  entitled  on
account of such default;  provided that if there is any disagreement between the
defaulting  Participant  and any other  Participant  as to whether a default has
occurred,  then the matter may be submitted to arbitration under Article 16, and
the Participant in question shall not be considered in default of any obligation
determined  by the  arbitration  so long as it  commences  to remedy the default
within 10 days after the  arbitration  decision or within such longer  period as
may be fixed in the arbitration award.

Time of The Essence

Time shall be of the essence in the performance of this Agreement.

Enurement

19.8 This  Agreement  shall  enure to the  benefit  of and be  binding  upon the
parties hereto and their respective successors and permitted assigns.

Rule Against Perpetuities

19.9 If any right,  power or  interest of any party in any  property  under this
Agreement would violate the rule against  perpetuities,  then such right, power,
or interest shall terminate at the expiration of 20 years after the death of the
last survivor of all the lineal  descendants of Her Majesty,  Queen Elizabeth II
of England, living on the date of execution of this Agreement.

Remedies

19.10  Each of the  Participants  agrees  that its  failure  to comply  with the
covenants and  restrictions  set out in Articles 12, 13 and 14, could constitute
an injury and damage to the other Participants  impossible to measure monetarily
and, in the event of any such failure, the other Participants shall, in addition
and without  prejudice to any other rights and remedies at law or in equity,  be
entitled to injunctive relief restraining,  enjoining or specifically  enforcing
any acquisition,  sale, transfer,  charge or encumbrance save in accordance with
or as  required  by the  provisions  of  Articles  13 or 14, or  restraining  or
enjoining any breach of Article 12, as the case may be, and any party  intending
to breach the  provisions  of said  Articles  12, 13, or 14,  hereby  waives any
defence it might have in law to such injunctive or other equitable relief.

to an Agreement between Leader Mining  International Inc. and Kores Canada Corp.
dated as of the 10th day of November, 1999.

                           NET SMELTER RETURN ROYALTY

Interpretation

1.1 Where used herein:

     "Agreement" means the above-referenced agreement,  including any amendments
     thereto or renewals or extensions thereof;

     "Deductions"  means the  deductions  from Gross Sales that are permitted in
     determining the Royalty under the Agreement;

     "Gross Sales" means the gross revenues from sales of Mineral Products;

     "Holder" means the person or persons that are from time to time entitled to
     be paid the Royalty under the Agreement;

     "Royalty" means the Net Smelter Return Royalty payable under the Agreement;

     and all other  defined terms used in this  Schedule,  which are not defined
     herein, have the meanings ascribed thereto in the Agreement.

1.2 All calculations  and computations  relating to the Royalty shall be carried
out in accordance with Canadian generally accepted accounting  principles to the
extent that such  principles  are not  inconsistent  with the  provisions of the
Agreement and this Schedule 2.

Calculation and Payment of Royalty

2.1 The Royalty shall be:

     (a)  calculated by each  Participant as to its respective share of Royalty.
          and

     (b)  calculated and paid on a quarterly  basis within 45 days after the end
          of each quarter of the  Operating  Year,  based on the Gross Sales and
          Deductions for such quarter which relate to the Participant's share of
          Mineral Products sold during the quarter.

2.2 The Royalty shall be payable by each Participant as follows:

     (a)  each payment of Royalty will be accompanied by an unaudited  statement
          indicating  the  calculation  of the Royalty  hereunder in  reasonable
          detail and the Holder will receive, within 3 months of the end of each
          Operating  Year,  an annual  summary  unaudited  statement (an "Annual
          Statement")  showing  in  reasonable  detail  the  calculation  of the
          Royalty for the last completed Operating Year;

Joint Venture Agreement                     Leader Mining International Inc. and
                                                              Kores Canada Corp.


     (b)  the  Holder  will have 45 days from the time of  receipt of the Annual
          Statement  to question the  accuracy  thereof in writing and,  failing
          such objection,  the Annual Statement will be deemed to be correct and
          unimpeachable thereafter;

     (c)  if the Annual  statement  is  questioned  by the  Holder,  and if such
          questions  cannot be resolved  between the Holder and the  Participant
          that  prepared  the Annual  Statement,  then the  Holder  will have 12
          months  from the time of receipt of the  Annual  Statement  to have it
          audited, which will initially be at the expense of the Holder;

     (d)  the audited Annual  Statement will be final and  determinative  of the
          calculation  of the Royalty for the audited period and will be binding
          on the Holder and the Participant  that prepared the Annual  Statement
          and any  overpayment of Royalty will be deducted from future  payments
          of Royalty and any  underpayment of Royalty will be paid to the Holder
          forthwith;

     (e)  the costs of the audit will be borne by the Participant  that prepared
          it  if  the  Annual  Statement   overstated  the  Royalty  payable  or
          understated  the Royalty payable by more than 1% and otherwise will be
          borne  by the  Holder,  and if the  party  that  prepared  the  Annual
          Statement  is  obligated  to pay  for  the  audit  it  will  forthwith
          reimburse the Holder for any of the audit costs which it has paid; and

     (f)  the Holder  will be  entitled to  examine,  on  reasonable  notice and
          during normal business hours, such books and records as are reasonably
          necessary  to verify  the  payment  of the  Royalty to it from time to
          time,  provided  however that such  examination  shall not  reasonably
          interfere with or hinder the Participant's operations or procedures.

Inclusion of Income Taxes in Costs

3.1 Notwithstanding  anything to the contrary herein contained,  if there is any
tax  ("Tax") on income  paid or payable by a  Participant  by reason of the fact
that the  Royalty,  in whole or in part,  is or  becomes  non-deductible  to the
Participant for the purposes of calculating its taxable income:

     (a)  if the  Royalty is not  required to be  included  in  determining  the
          taxable  income of the  Holder,  the  Participant  may deduct from the
          amount of Royalty otherwise  payable by it hereunder,  the full amount
          of the Tax; and

     (b)  if the  Royalty is in whole or in part  required to be included by the
          Holder in its  taxable  income,  the  Participant  may deduct from the
          amount of Royalty otherwise  payable by it hereunder,  that percentage
          of such Tax that equals the  percentage  of the  Royalty  which is not
          required to be included by the Holder in its taxable income,  in order
          for the Tax to be shared pro rata by the Participant and the Holder.

Segregation of Royalty

4.1 The  determination  of  Royalty  hereunder  is  based  on the  premise  that
production will be developed solely on the Property. Other mining properties may
be  incorporated  with the Property into a single mining project and the metals,
ores or concentrates  pertaining to each may be blended at the time of mining or
at any time thereafter,  provided however, that the respective mining properties
(including the

Property)  shall bear and have  allocated  to them their  proportionate  part of
expenditures  relating  to the  bringing  of such  single  mining  project  into
Commercial Production and thereafter operating the same and shall have allocated
to them  the  proportionate  part of the  revenues  realized  from  such  single
operation all as determined in accordance  with  generally  accepted  accounting
principles  and from records  maintained by the Operator.  The Holder shall have
the  right,  during  reasonable  business  hours  and upon  prior  notice to the
operator and Participant, to enter upon the mining properties and to inspect the
plant and  procedures  followed  with  respect  to  allocations  made under this
paragraph  provided  that such  entry  shall be at the sole risk and cost of the
Holder.  If the parties  disagree on the allocation of actual proceeds  received
and  deductions  therefrom,  such shall be referred to arbitration in the manner
provided in Article 16 of the Agreement and the arbitrator  shall have reference
first to the  Agreement,  and then,  if necessary,  to practices  used in mining
operations  that are of a similar  nature.  The arbitrator  shall be entitled to
retain  such  independent  mining  consultants  and  financial  advisors  as  he
considers  necessary.  The decision of the arbitrator shall be final and binding
on the parties.

1.6 Not less than 15 days prior to the first day of each month the  Operator may
bill each  Non-Operator by way of a Cash Call, in which it will credit or deduct
an amount equal to any adjustment in the Costs  recorded in any previous  month.
Not later than the first day of the month to which the advance  relates,  or, if
the first day of the month is not a Business  Day,  then on the next  succeeding
day that is a Business Day, each Non-Operator will remit its Proportionate Share
of the advance so requested.

1.7 The amount of any Cash Call billed in accordance  with  paragraph 1.7 may be
increased to include a special advance if authorized by the Management Committee
or if the Costs for the  relevant  month are  expected by the Operator to exceed
the  forecast  Costs  for the  month  as a  result  of the  acceleration  in the
incidence of Costs provided for in any Program,  Production Program or Operating
Plan but previously forecast to arise in a subsequent month.

1.8 Each Non-Operator will pay Cash Calls from the Operator within 15 days after
receipt thereof.

1.9 All advances from the parties  (including the Operator) will be deposited in
the Joint Venture Account maintained pursuant to the Agreement.

Unpaid Accounts

1.10 If  payment  of any Cash Call is not made  within  the time  stipulated  in
paragraph 4.3 of these Accounting Procedures,  then the provisions of paragraphs
7.9, 8.7 and 9.6 of the Agreement, as applicable, will apply.

Right to Protest Cash Calls

1.11 Payment of any Cash Calls will not prejudice the right of  Non-Operator  to
protest or question the  correctness  thereof.  Subject to paragraph  3.6 of the
Agreement,  all  statements  rendered to a  Non-Operator  will  conclusively  be
presumed to be true and correct after 90 days  following the end of the calendar
year to which the statement  relates,  unless within the said 90-day period, the
Non-Operator takes written exception thereto and makes claim on the Operator for
adjustment in accordance  with the  provisions of paragraph 3.6 of the Agreement
mutatis mutandis.  The provisions of this paragraph will not prevent adjustments
resulting from physical inventory of Material.

Audits

of the Joint Operation on a calendar year basis and within 90 days after the end
of each calendar year.

1.13 In addition,  each  Non-Operator,  upon notice in writing to the  Operator,
will have the right to audit the Operator's  accounts and records maintained for
the Operating  Account for any  Operating  Year within the six month period next
following  the end of the  Operating  Year.  A request for such an audit will be
reasonable  so as to minimize  administrative  problems  for the  Operator.  Any
claims of  discrepancies  disclosed  by an audit  will be made in writing to the
Operator  within the nine month period next  following  the end of the Operating
Year. Cost of such an audit will be borne by the requesting Non-Operator.

Records

enable an effective  reconciliation of any physical inventory with the Operating

Dear Sirs:

Re: Joint Venture Agreement ("Agreement") dated November 10,1999 between Kores
Canada Corp. and Leader Mining International Inc.

In  connection  with our joint  venture  pursuant  to the  Agreement,  this will
evidence  our agreed  arrangements  with  respect to the  marketing  and sale of
certain  of the  Production  from  the  joint  venture  property  if any of such
Property should achieve Commercial Production as contemplated in the Agreement.

If Leader  intends from time to time to market and sell in the Republic of Korea
any of its share of Production  from the  Property,  then it will first offer to
conduct such marketing and sales utilizing Kores as its agent in the Republic of
Korea for such purposes.  Provided that any commission that Kores then quotes in
response to Leader for carrying out such services is competitive in the industry
at such time for  comparable  services  and a  comparable  quantity  of  mineral
products,  then Leader will engage Kores as its agent entitled to the commission
quoted or as may be  otherwise  agreed for its  services  and  otherwise  on the
customary terms and conditions in the industry.

Capitalized  terms used herein and not defined herein have the meanings ascribed
to those terms in the Agreement.

                                      -2-

Please  indicate  your  agreement  with the  foregoing by signing the  duplicate
original of this letter in the space indicated below and return it to us.

Yours very truly,

KORES CANADA CORP.
