 3.6  Demobilization. During the Option, Donner agrees that should the Parties elect to demobilize the project at the end of the first field season and the Firm Commitment has been completed through Expenditures in the field, then the demobilization costs will be borne by Donner in addition to the Firm Commitment. In each subsequent year of the earn-in, demobilization will form part of the work program budget proposed by the Operator unless the parties mutually agree in writing to waive demobilization. In such event, should demobilization occur after the initial budget is spent, then Donner will bear the cost. Notwithstanding the above, either Party may elect not to demobilize the camp. In such case, the party that so elects will assume all costs for the demobilization. During the Option, any costs related to the demobilization can be applied towards Expenditures.

 11.11  Condition Precedent. Submission to arbitration under this section 11 shall be a condition precedent to bringing any action with respect to this Agreement.
 
 SECTION 12. - AREA OF INTEREST.
 
 12.1  Area of Interest. If either Party acquires, directly or indirectly, any interest in any property which is all or partly within an area of interest, as described in coordinates identified in Schedule A (the  Area of Interest ) and shown for illustrative purposes only on a map attached hereto as Schedule B, the acquiring Party must disclose this acquisition (including all costs) promptly to the other Party. The other Party will then have 30 days to elect to make that portion of the property which is within such Area of Interest part of the Property. During the Option Period, if the other party elects to include such portion as part of the Property, the acquisition costs shall be paid by Donner and shall be credited to its earn-in Expenditures. During the Joint Venture, each party shall pay acquisition costs in proportion to its Joint Venture Interest if the parties elect to include such new property as part of the Property. If the other Party fails to make such election or payment within such 30 day period, such property shall not form part of the Property. The Area of Interest shall expire six months after the term of this Agreement. Should Donner withdraw from the Agreement, the Area of Interest will immediately terminate, provided that Donner shall be prohibited from making any acquisition in the Area of Interest for a period of six months after withdrawal.
 
 12.2  Under the Area of Interest of this Agreement, Inuit Owned Lands (IOL) type two lands may be acquired by Falconbridge through the negotiation of agreements with Nunavut Tunngavik Incorporated (NTI).  In any such case, prior to Falconbridge entering into negotiations with NTI, it shall consult with Donner and Donner shall have 10 days after such consultation to elect in writing whether it wishes to participate and following such election, to have the subject IOL area of lands included as Property should Falconbridge be successful in concluding an agreement with NTI under terms acceptable to Donner. Falconbridge shall make every reasonable effort to avoid including committed expenditures within an NTI agreement.  Should Donner elect to participate:
 
 14
  (a)  the IOL lands will be included under the terms of this Agreement and Donner shall
 participate at its proportion of Participating Interest.
 
 (b) During an IOL option, all expenditures and payments made in connection with the NTI and
 IOL lands shall be included as Expenditures under this Agreement.
 
 (c) Should Donner elect to participate in an NTI agreement and a component of that agreement
 is committed expenditures then,
 In the first year of this Agreement, any committed expenditures under any NTI agreement will be included under the Firm Commitment expenditures under this Agreement.If committed expenditures arise under any NTI agreement after Donner has met its Firm Commitment under this Agreement, then by electing to participate in an IOL agreement, Donner so commits the additional funds in addition to the Firm Commitment. These funds will qualify under Donners earn-in requirements or its Participating Interest as the case may be.
(d)Any expenditures under an agreement with NTI that are committed expenditures shall be
advanced from Donner to Falconbridge for the year in which they occur through a specific
Cash Call in advance of signing a definitive agreement with NTI.

(e)Upon the formation of a Joint Venture, any obligations under a NTI agreement shall be
funded in accordance with Participating Interests.

In the event that Donner elected to participate in an NTI agreement and the Option is terminated prior to any firm commitments on expenditures or payments under NTI agreements being fully satisfied, notwithstanding that Donner shall no longer have any interest in the Property, except for the NTI lands under agreement, Donner shall pay to Falconbridge upon termination an amount equal to the outstanding amount of firm expenditures or payments that would be due and payable under NTI agreements on or before December 31, 2006.  (For greater certainty, if the Option is terminated in the first year of the Agreement, any payment due under section 3.2(1) shall credited to the payment due under this section).

In the event that Donner elects not to participate in the acquisition of the IOL area of lands, Falconbridge shall be entitled to proceed to acquire such area of lands on its own account and behalf without any obligation to Donner and such land shall be excluded from the meaning of Property and Area of Interest.

15

SECTION 13. - GENERAL.

13.1No Obligations.No term of this Agreement and no act or omission of Donner shall oblige Donner:

(a)to fund any Expenditure referred to in section 3.2 other than the Firm Commitment and any commitments including costs arising under section 3.6, under section 4.3 or under section 12.2;

(b)to exercise the Option;

(c)to bring the Property, or any part thereof, into Commercial Production; or

(d)to take any action, other than those actions expressly required by this Agreement.

13.2Right of First Refusal.During the Option Period, Falconbridge, and once the Joint Venture is exercised and provided Donner has at least a 50% Joint Venture Interest, Donner as well, has the right of first refusal to purchase all or any part of the other party's interest in the Property or under this Agreement, including a party's Joint Venture Interest or Royalty interest. If Donner or Falconbridge (the "Offeror") wishes to sell, or receives any good faith offer which the Offeror is prepared to accept to purchase, all or any part of such interest (the "Offered Interest"), the Offeror shall give written notice to the other party (the "Offeree") of all the material terms of such proposed sale (the "Sale Terms"). The Sale Terms must contain a sale price stated in cash. The Offeree shall then have 30 days, calculated from the date of receipt of the notice by the Offeror, within which to elect to purchase the Offered Interest on terms not less favourable to the Offeree than the terms contained in the Sale Terms. If the Offeree does not make an election within such 30 day period, the Offeree shall be deemed to have elected not to purchase the Offered Interest. If the Offeree does not elect to purchase the Offered Interest, then the Offeror may sell the Offered Interest to any good faith third party on terms no more favourable to such third party than the terms contained in the Sale Terms within the 45 day period immediately following the Offeree's 30 day election period. If the Offeror does not complete the sale of the Offered Interest within such 45 day sale period, then the Offeree shall once again have the right of first refusal to purchase all or any part of the Offered Interest not sold by the Offeror. Notwithstanding any term in this section 13.2, no party with a Royalty interest has any rights under this section 13.2, including the right to be the Offeree. For greater certainty, the right of first refusal shall not apply to a corporate merger, consolidation, amalgamation or reorganization of a Party, provided the surviving entity will assume the right, obligations and liabilities of such Party.


13.3Assignment and Benefit of Agreement.Notwithstanding section 13.2, Donner may not assign this Agreement or any rights hereunder or in the Property without the prior written consent of Falconbridge,such consent not to be unreasonably withheld, except that Donner may assign this Agreement to an affiliate (as that term is defined in theBusiness Corporations Act(Ontario)) by delivering notice to that effect to Falconbridge. Any assignee must agree in writing to be bound by the terms of this Agreement. Any such assignment to such an affiliate shall not release the assigning party from any liability under this Agreement. This Agreement enures to the benefit of and binds the parties and their respective successors and permitted assigns.

16

13.4Notwithstanding any other term in this Agreement, during the Option Period Falconbridge may assign, without the consent of Donner, this Agreement (including all of Falconbridge's rights and obligations) if the purchaser delivers to Donner a written undertaking of the purchasing party to be bound by the terms of the Agreement relating to Falconbridge. Upon such an assignment, Falconbridge shall be relieved of all its obligations under this Agreement. Once Donner has exercised the option and has at least a 50% Joint Venture Interest, section 13.3 shall apply to Falconbridge as well, notwithstanding this section.

13.5Independent Legal Advice.Donner acknowledges that Falconbridge advised Donner to seek independent legal advice in respect of this Agreement. Donner has either obtained such advice or waived its right to obtain such advice. Donner acknowledges that Donner has received no legal advice from Falconbridge's legal counsel.

13.6Government Assistance.Any grant or other form of governmental financial assistance received by a Party with respect to Mining Operations shall be shared by the Parties, in the proportion of their respective Expenditures at the time that such grant or financial assistance applies.

13.7Further Assurances.Each party shall from time to time promptly execute and deliver all further documents and take all further action reasonably necessary or desirable to give effect to the terms and intent of this Agreement.

13.8Waivers.No waiver of any term of this Agreement by a party is binding unless such waiver is in writing and signed by the party entitled to grant such waiver. No failure to exercise, and no delay in exercising, any right or remedy under this Agreement shall be deemed to be a waiver of that right or remedy. No waiver of any breach of any term of this Agreement shall be deemed to be a waiver of any subsequent breach of that term.

13.9Amendments.No amendment, supplement or restatement of any term of this Agreement is binding unless it is in writing and signed by each party.

13.10Force Majeure.Notwithstanding any term in this Agreement, if a party is at any time delayed from carrying out any action under this Agreement due to circumstances beyond the reasonable control of such party (aside from circumstances arising from the financial difficulty of such party), acting diligently, the period of any such delay shall be excluded in computing, and shall extend, the time within which such party may exercise its rights and/or perform its obligations under this Agreement.

17

13.11Notice.Any notice or other communication required or permitted to be given under this Agreement must be in writing and shall be effectively given if delivered personally or by overnight courier or if sent by fax, addressed in the case of notice to Donner or Falconbridge, as the case may be, as follows:

SCHEDULE C- JOINT VENTURE TERMS


SECTION1. - RELATIONSHIP OF PARTIES.

The relationship of the Parties in the Joint Venture shall not be, and shall not be construed to be, a partnership relationship, an agency or legal representative relationship or a fiduciary relationship. Except as otherwise expressly provided in this Agreement, the rights, privileges, powers, duties, liabilities and obligations of the Parties shall be as joint venturers and shall be several and not joint or joint and several.

The Parties acknowledge and agree that separate Joint Ventures shall be formed in the event Falconbridge exercises its 15% bump-up right in respect of a portion of the Property or in respect of any Property held under a NTI agreement., where NTI exercises a back-in right or where a Party so elects in the event the management committee decides to proceed with the commercial development of a portion of the Property.

SECTION2. - CALCULATION OF JOINT VENTURE INTERESTS.

2.1Initial Calculation.On the date that the Joint Venture is formed, Donner and Falconbridge are deemed to have made the following initial Expenditures:

Falconbridge
Donner
TotalDeemed Expenditures:
$ 4,950,000
$ 4,950,000
$ 9,900,000Joint Venture Interest
50%
50%
100%

2.2Non-Participation.If the non-Operator elects not to participate in any Program or fails to notify the Operator of its election within the said sixty (60) day period referred to in paragraph 5.2 hereof (in which event the non-Operator shall be deemed to have elected not to participate in and contribute its proportionate share of Expenditures), its undivided Joint Venture Interest shall abate in favour of the Operator in the ratio that its actual and deemed Expenditures in the Joint Venture is of the total actual and deemed Expenditures of both Parties.

2.3Calculation on Ongoing Basis.Donner's and Falconbridge's, as the case may be, Joint Venture Interest, calculated at any time and from time to time, shall be determined in accordance with the formula:

1

A =Bx 100%, where
C

(a)A is Donner's or Falconbridge's, as the case may be, Joint Venture Interest;

(b)B is an amount equal to Donner's or Falconbridge's, as the case may be, deemed Expenditures under section 2.1 of this Schedule C, plus all of Donner's or Falconbridge's, as the case may be, Expenditures made after the formation of the Joint Venture; and

(c)C is an amount equal to the Parties' total deemed Expenditures under section 2.1 of this Schedule C plus all of the Parties' Expenditures made after the formation of the Joint Venture.

2.4Extinguishing Joint Venture Interest.If Donner's or Falconbridge's Joint Venture Interest is reduced to 10% or less, then Donner's or Falconbridge's, as the case may be, Joint Venture Interest shall be automatically extinguished and converted to the Royalty, if the Property is brought into Commercial Production by Donner or Falconbridge, as the case may be. The Joint Venture is automatically terminated upon such conversion, and the surviving Party shall become the sole owner of a 100% interest in the Property (subject to any terms and conditions of a NTI agreement including lesser ownership interest).

2.5A separate Project Area Joint Venture shall be formed in respect of any portion of theProperty (Project Area) that is subject to:

(a)Falconbridges election to exercise its rights to acquire an additional 15% interest in a Project Area under section 6;

(b)NTI electing to back-in for a undivided 20% or other interest in respect of IOL lands under a NTI agreement; and/or

(c)a decision by the Management Committee to proceed with commercial development of a Project Area.

2.6The area of Property pertaining to such Project Area shall be removed from the meaning of Property of the Joint Venture and provisions of this Schedule C shall applymutatis mutandisto such Project Area and Project Area Joint Venture.  For greater certainty, deemed and actual Expenditures pertaining to the remaining Property shall not be adjusted as a consequence of the creation of new Joint Venture for the Project Area and further Expenditures incurred on the Project Area shall not be included in any calculation in the remaining Property and Joint Venture.

2

2.7Each Partys Participating Interest in the new Project Area Joint Venture upon its formation shall be initially equal to its Participating Interest in the Joint Venture at such time.   The denominator C under section 2.3 for a new Project Area Joint Venture at it formation shall be the same as the denominator C for the Joint Venture at such time.   Under Falconbridges 15% bump-up right, the Participating Interests shall not be adjusted upwards by 15% for Falconbridge and downwards by 15% for Donner until such time that Falconbridge has delivered the Feasibility Study as set out in section 6.  Upon such delivery the denominator C shall be increased by the Expenditures incurred by Falconbridge in carrying-out the Feasibility Study, with the deemed expenditures of each party adjusted to take into account the 15% bump-up of interest by Falconbridge and resulting Participating Interests.

2.8In the case of NTI exercising a back-in right in respect of a Project Area comprised of IOL lands, its interest shall be taken pro-rata from Falconbridge and Donner.   For example, if Falconbridge exercised its bump-up right and the resulting Participating Interests were 65/35 Falconbridge/Donner respectively, upon NTI exercising it back-in right, the Participating Interests would be 52/28/20 Falconbridge/Donner/NTI, respectively.   In the event that NTI had exercised its back-in rights to a Project Area and the resulting Participating Interests were 40/40/20 and subsequently Falconbridge exercised its15% bump-up right (15% of 80% - 12%), Falconbridges bump-up right pertains to 15% of aggregate Participating Interest of Falconbridge and Donner and the Participating Interests would be 52/28/20 Falconbridge/Donner/NTI, respectively.  Subject to any provisions of the applicable NTI agreement, the denominator C would calculated as set out in section 2.7 and the deemed expenditures of each Party adjusted accordingly to take into account the resulting Participating Interests.

SECTION3. - MANAGEMENT COMMITTEE.

3.1Establishment.Promptly upon the formation of the Joint Venture, the Parties shall establish the Management Committee. One Representative and one alternate shall be appointed in writing by each Party and re-appointed from time to time.

3.2Powers and Obligations.Except as expressly provided otherwise in this Agreement, the Management Committee is empowered to make all strategic and planning decisions regarding the Joint Venture. Accordingly, the Management Committee is responsible for revising, as deemed appropriate, Programs submitted by the Operator, for approving all Programs and for evaluating the results of all Programs.

3

3.3Calling of Meetings.Meetings of the Management Committee shall be held at such time, date and place as may be determined by the Operator on at least 20 days notice or as may be determined by the non-Operator on at least 30 days notice. The Representatives may waive the notice period required for any meeting. Any notice must include the time, date, place and agenda of each meeting. On receipt of any such notice, the receiving Party may add any item to the agenda, if the receiving Party notifies the other party of the addition at least 10 days before the meeting. No item which is not on the agenda may be discussed without the consent of the Representatives. Individuals other than the Representatives may attend meetings of the Management Committee with the consent of the Representatives.

3.4Attendance at Meeting by Phone.Any Representative may attend a meeting of the Management Committee by telephone or video conference call and such Representative is deemed to be present at such meeting.

3.5Quorum at Meetings.The quorum for any meeting of the Management Committee is the one Representative from each of the Parties. If a quorum is not present at the time and place set for a meeting, then the meeting shall be adjourned to the same place and time of the next week. At the continuation of the adjourned meeting the Management Committee may conduct business, if a notice regarding the continuation of the adjourned meeting was sent to the Party whose Representative did not attend the first portion of the meeting. In no other circumstance may business be transacted at a meeting of the Management Committee without a quorum being present.

3.6Secretary of Meetings.The Representatives shall appoint a secretary to act as a secretary of the Management Committee at the beginning of each meeting of the Management Committee. Such secretary shall carry out the duties of the secretary of the Management Committee until such secretary's replacement is appointed. The secretary shall prepare and maintain minutes of each meeting of the Management Committee. The secretary shall distribute to the Representatives such minutes, as soon as practicable following each meeting. The secretary shall also maintain, and distribute to the Representatives, copies of all correspondence and instruments received, sent or signed by the Management Committee or the Representatives (when acting in the capacity of a Representative).

3.7Making Decisions.All decisions of the Management Committee shall be by majority vote by the two voting Representatives, who shall each have the number of votes equal to such Representative's respective Party's Joint Venture Interest from time to time. In the event of an equality of votes, the Operator's Representative shall have an additional and casting vote. Alternatively, the Management Committee may transact any business by a written instrument signed by a Representative of each Party. Each decision of the Management Committee shall be final and binding on the Parties.

4

3.8Consent of Management Committee Required.Notwithstanding any term in this Agreement, the Operator shall not take any of the following actions without obtaining the prior written unanimous consent of the Management Committee:

(a)create, or permit to remain, any Liens, upon any Joint Venture Asset, except for any Liens which are customary in the circumstances of a mining exploration joint venture;

(b)abandon, sell or otherwise dispose of the Property, or any part thereof; or

(c)settle any suit, claim or demand with respect to the Joint Venture involving an amount in excess of $50,000.

Notwithstanding section 3.8(b), the Operator may unilaterally dispose of any part of the Property by giving the non-Operator 60 days written notice of the proposed disposal. On receipt of such notice, the non-Operator may elect to acquire all of that part of the Property subject to the proposed disposal by delivering a notice to the Operator to this effect at least 15 days before the expiry of such 60 day notice period. On receipt of the notice from the non-Operator, the Operator shall promptly transfer the part of the Property subject to the proposed disposal to the non-Operator. The non-Operator shall pay for all transfer costs. Upon completion of the transfer of the part of the Property subject to the proposed disposal to the non-Operator, the part of the Property subject to the proposed disposal will no longer be subject to this Agreement, except that the non-Operator shall indemnify and save harmless the Operator on its own behalf and as trustee for its shareholders, directors, officers, employees, agents, contractors and representatives from and against all suits and other proceedings, claims, demands, damages, liabilities, losses, costs and expenses (including lawyers' fees and disbursements) which the Operator may suffer or incur in respect of the part of the Property subject to the proposed disposal.

SECTION4. - THE OPERATOR, ITS POWERS AND OBLIGATIONS.

4.1Initial Operator.Upon the formation of the Joint Venture, Falconbridge shall automatically become the first Operator.

4.2Resignation and Replacement.The Operator may resign as Operator upon notifying the non-Operator in writing of its resignation at any time after a Program has been approved by the Management Committee but before the commencement of the implementation of such Program, or at any time if no Program is being carried out at that time. The Management Committee shall have the right to appoint a new Operator if:

5

(a)the Operator defaults in its obligations as operator hereunder and fails to commence and diligently prosecute measures to remedy such default within thirty (30) days after the non-Operator shall have given written notice to the Operator of such default specifying in such notice the nature of the default;

(b)the Joint Venture Interest of the Operator becomes less than fifty percent (50%); or

(c)pursuant to section 5.1 of this Schedule C, the Operator fails to submit a Program requiring minimum Expenditures of at least Fifty Thousand Dollars ($50,000) to the Management Committee within six (6) months of the completion of the previous Program.

Provided however that in the event of the occurrence of (c) above, the non-Operator shall have the right within a period of ninety (90) days of the occurrence of such event to prepare and deliver to the Operator and the Management Committee a copy of a Program requiring minimum Expenditures of at least Fifty Thousand Dollars ($50,000) and to carry out and complete such a Program within a period of one (1) year. Upon fulfillment of the foregoing, the provisions of this section 4.2 and section 5 shall for all purposes of this Agreement apply mutatis mutandis as if for such Program the Operator was the non-Operator and the non-Operator was the Operator. Provided further that notwithstanding the foregoing, Donner so long as it retains at least a fifty percent (50%) interest in the Joint Venture, shall continue to have the right to retain its position as Operator in accordance with this paragraph 4.2 following completion of a Program by the non-Operator.

On any change or replacement of the Operator, the retiring Operator shall transfer all data, documents, reports, records, accounts, samples and assays in its possession or control, and relating to the Mining Operations or the Property, to the incoming Operator.

4.3Powers and Obligations.Subject to the approval of each Program by the Management Committee, the powers and obligations of the Operator shall be as follows:

The Management Committee must approve each Program prior to implementation. Each Program shall cover a period of up to 12 months or such other period as the Parties may agree. Each Program must contain:

(1)a reasonably detailed outline of all Mining Operations which the Operator contemplates carrying out on the Property and detailing the areas on the Property to be subject to such Mining Operations and the time frame for each of the major elements of the Mining Operations;

(2)a reasonably itemized budget, broken down by month, of the projected Expenditures under the Program; and

(3)the estimated amount and date of each payment that the non-Operator would have to make to the Operator.

5.2Election by non-Operator.The non-Operator may elect, on delivering notice in writing to the Operator within 60 days of the approval of each Program by the Management Committee, to participate in the Program to the extent of the non-Operator's then Joint Venture Interest (but not to any lesser extent).

5.3Expenditures Made Proportionately.The Operator shall carry out each Program approved by the Management Committee. The Operator will contribute its proportionate share towards the Expenditures to be made under each Program as set out in section 5.4 of this Schedule C. Each payment by the Operator in respect of an Expenditure will be deemed to be made in proportion to the Parties' Joint Venture Interests, so long as each of the Parties has provided its proportionate share of the funding in respect of the Program.

5.4Payments to Operator.If the non-Operator elects to participate in a Program, the Operator may submit a cash call invoice to the non-Operator up to 90 days preceding each three month period in which Expenditures are to be made under a Program. The invoice must set out the estimated Expenditures under the Program for such three month period, multiplied by the non-Operator's Joint Venture Interest. Within 30 days of receipt of such invoice, the non-Operator shall pay the Operator the invoice amount. The Operator may also submit other invoices relating to reconciliations, bills, accounts or other requests for payment in respect of any Expenditures made by the Operator under a Program or otherwise in accordance with this Agreement. Such invoice must set out the total amount involved, multiplied by the non-Operator's Joint Venture Interest. Within 30 days of receipt of such invoice, the non-Operator shall pay the Operator the invoice amount. If the non-Operator fails to make any payment to the Operator under this section 5.4 of this Schedule C within any applicable 30 day payment period, the non-Operator shall make such payment together with an interest payment, calculated at the rate equal to the annual rate of interest announced from time to time by the Canadian Imperial Bank of Commerce as its reference rate then in effect for determining interest rates on Canadian dollar commercial loans in Canada (commonly known as its prime rate), plus 10%, for the period commencing on the expiry of such 30 day payment period and terminating on the date that full payment is made. If the non-Operator fails to make full payment, including in respect of interest, to the Operator within 60 days of the expiry of the applicable 30 day payment period, section 5.6 of this Schedule C applies.

5.5Failure to Participate.If either Party does not elect to participate in a Program, its interest shall be diluted in accordance with section 2.2 of this Schedule C.

5.6Failure to Make Payment by non-Operator.If the non-Operator fails to make a required payment within the 60 day period referred to in section 5.4 of this Schedule C, the non-Operator's Joint Venture Interest shall be automatically extinguished and converted to a 1% Royalty if the Property is brought into Commercial Production by the Operator. The Joint Venture is automatically terminated upon such conversion.

5.7Failure to Spend at Least 80% of Budget.If the non-Operator does not elect to participate in a Program and the Operator does not make Expenditures under the Program at least equal to 80% of budgeted Expenditures, the non-Operator shall not have its Joint Venture Interest reduced in accordance with section 2.2 of this Schedule C if the non-Operator promptly pays the Operator, following the completion of such Program, an amount equal to the total Expenditures made under such Program, multiplied by the non-Operator's Joint Venture Interest, determined at the commencement of such Program.

5.8Expenditures More Than 20% Above Budget.Expenditures made by the Operator exceeding the Expenditures contemplated by the Program by less than 20% will be funded by the Parties in proportion to their Joint Venture Interests. Expenditures made by the Operator exceeding the Expenditures contemplated by the Program by more than 20% will be funded solely by the Operator, unless otherwise agreed by the Parties in writing. Unless otherwise agreed by the Parties in writing, any such payments exceeding the Expenditures contemplated by the Program by more than 20% which are made by either the Operator or the non-Operator will not form part of the calculations used to determine the Joint Venture Interests of the Parties in accordance with section 2.2 of this Schedule C.

10

5.9Return of Surplus Monies.If, after completion of any Program, the Operator is in possession of any moneys contributed by the non-Operator and which, in the Operator's opinion, are not required for the discharge of obligations relating to such Program, the Operator shall repay such moneys to the non-Operator.

5.10Failure to Submit Program to Management Committee.If the Operator does not submit a Program for Mining Operations involving Expenditures of at least $50,000 to the Management Committee for approval within a period of at least 12 months from the date of completion of the last Program, then the non-Operator may propose a Program for Mining Operations to the Management Committee for an amount not less than $50,000. If the non-Operator makes such a proposal and the Program is approved by the Management Committee, the Operator shall carry out such Program and fund its proportionate share. If the Management Committee does not approve such Program, the non-Operator may, notwithstanding section 4.2 of this Schedule C, become the Operator and carry out the Program. Following the completion of such Program section 4.2 of this Schedule C shall apply once again.

SECTION6. - FALCONBRIDGES BUMP-UP RIGHT.

Provided Falconbridge has at least a 35% interest in the Joint Venture, it shall have the right to earn an additional 15% interest in a Project Area within the Property at any time by electing to be responsible for and carrying out a Feasibility Study. Expenditures relating to the Feasibility Study shall be the responsibility of Falconbridge. Upon delivery of the Feasibility Study to Donner, Falconbridge shall have earned its additional 15% Joint Venture Interest. Falconbridge may elect not to continue with its bump-up right, provided that Falconbridge will not receive any credit for its Expenditures related to the Feasibility Study.

SECTION 7. - DEALINGS WITH AFFILIATES.

Any Joint Venture Assets that the Operator may purchase, lease or rent from an Affiliate shall be purchased, leased or rented at fair market value. The cost of all work which the Operator may contract to an Affiliate shall be equal to the fair market value of such work. Any Joint Venture Assets that the Operator may sell or otherwise dispose of to an Affiliate shall be sold or otherwise disposed of at fair market value. The Operator shall pay the net proceeds received in respect of such Joint Venture Assets, if any, to the Parties in proportion to their respective Joint Venture Interests. The Operator shall give the non-Operator written notice of any significant transaction with an Affiliate and the non-Operator may, at any time within 12 months after it has received such notice, dispute whether such transaction was at fair market value.

SECTION 8. - USE OF SURPLUS JOINT VENTURE ASSETS.

The Operator may use any Joint Venture Assets which are no longer required for the Joint Venture for such other purposes and on such terms as the Operator may from time to time determine. The Operator shall pay the net proceeds received in respect of such Joint Venture Assets, if any, to the Parties in proportion to their respective Joint Venture Interests. If such surplus Joint Venture Assets are used by the Operator, outside the scope of the Joint Venture, or are used by an Affiliate of the Operator, outside the scope of the Joint Venture, then the net proceeds in respect of such use shall be deemed to be an amount equal to what could be obtained from an arms-length third party.

SECTION 9. - DISPOSITION OF SURPLUS JOINT VENTURE ASSETS.

Subject to section 13.2, the Operator may from time to time sell or otherwise dispose of such part of the Joint Venture Assets as are no longer required for Joint Venture operations.

SECTION 10. - INSURANCE PROCEEDS.

The Operator shall apply, to the extent determined by the Operator, any insurance proceeds received by the Operator in respect of any loss or damage to Joint Venture Assets towards the repair or replacement of the lost or damaged Joint Venture Assets. The Operator shall pay the remaining proceeds received in respect of such Joint Venture Assets, if any, to the Parties in proportion to their respective Joint Venture Interests.

SECTION 11. - SETTLEMENT PAYMENTS.

All losses, costs, expenses, claims or damages, including legal fees and disbursements, net of any insurance proceeds, incurred and paid by the Operator in settlement of any loss, cost, expense, claim, damage, judgment or similar matter (including a payment made, or an action taken, by the Operator as a result of an action of a governmental agency) shall constitute an Expenditure made by the Operator under the applicable Program. In addition, the non-Operator, in proportion to its Joint Venture Interest calculated on the date that the initial liability was incurred which gives rise to this indemnification obligation, shall indemnify and hold harmless the Operator for any loss, cost, expense, claim or damage, including legal fees and disbursements, suffered or incurred by the Operator in respect of a third party claim (including an action of a governmental agency which results in a payment made, or an action taken, by the Operator), except to the extent that such claim arose from the gross negligence or willful misconduct of the Operator.

12

SECTION 12. - LIABILITY OF OPERATOR.

The Operator shall not be liable to the non-Operator for any loss, cost, expense, claim or damage, including legal fees and disbursements, (including a payment made, or an action taken, by the Operator as a result of an action of a governmental agency) except to the extent that such loss, cost, expense, claim or damage is attributable to the gross negligence or willful misconduct of the Operator. In no event (including fundamental breach) shall the Operator be liable to the non-Operator for any indirect, special or consequential damages (including for loss of goodwill, loss of actual or anticipated profits or other economic loss), even if the Operator has been advised of the potential for such damages.

SECTION 13. - NO PARTITION.

No Party may seek or obtain partition of any of the Joint Venture Assets, including the Property, or any interest therein whether by way of physical partition, sale or otherwise. No statute, regulation or law providing for partition, or partition and sale, shall apply to any of the Joint Venture Assets.

SECTION 14. - NO RESTRICTION ON OTHER ACTIVITIES.

Each Party has the unrestricted right to engage in, and receive the full benefit of, any activity outside the scope of the Joint Venture, without consulting with, or accounting to, the other party, or permitting the other party to participate in such activity.

SECTION 15. - TERMINATION.

If the Parties agree to terminate the Joint Venture, the Operator may take any actions necessary or desirable to wind up the Joint Venture. All costs, charges and expenses of winding up the Joint Venture (including in respect of any reclamation) shall be for the account of the Joint Venture and the Parties shall divide the Joint Venture Assets in proportion to their Joint Venture Interests, although any loans advanced to the Joint Venture by a Party shall be satisfied before any other distribution of assets is made to the Parties. Once the said costs, charges and expenses have been paid in full, the Operator may sell the Joint Venture Assets (with the prior approval of the non-Operator, where Joint Venture Assets are sold for a total amount of in excess of $100,000) or distribute the Joint Venture Assets to the Parties in kind.
