7.0 EXPLORATION PROGRAMS

7.1 The Operator shall prepare draft Programs for consideration by the Management Committee. Unless otherwise agreed to by a Special Majority, each Program shall cover a calendar year. The draft Program shall contain a statement in reasonable detail of the proposed Mining Operations, estimates of all Exploration Costs to be incurred and an estimate of the time when they will be incurred, and shall be delivered to each Participant by no later than 60 days (unless otherwise agreed by the parties) prior to the date of the meeting of the Management Committee at which the Program is to be approved. Each draft Program shall be accompanied by such reports and data as are reasonably necessary for each Participant to evaluate and assess the results from the Program for the then current year and, to the extent not previously delivered, from earlier Programs.

7.2 The Management Committee shall review the draft Program prepared and, if it deems fit, adopt the Program with such modifications, if any, as the Management Committee deems necessary. The Operator shall be entitled to an allowance for a Cost overrun of 10% in addition to any budgeted Exploration Costs and any Costs so incurred shall be deemed to be included in the Program, as adopted.

7.3 The Operator shall forthwith submit the adopted Program to the Participants. Each Participant may, within 30 days of the date on which the Program is adopted, give notice to the Operator committing to contribute Exploration Costs for that Program in one of the following manners:

(a)

in proportion to its Interest by committing its Proportionate Share;

(b)

in some lesser proportion to its Interest by committing an amount less than its Proportionate Share; or

(c)

not at all, in which case the Participant elects not to contribute to the Program.

-13-

A Participant which fails to give that notice within the 30-day period shall be deemed to have elected not to contribute to that Program.

7.4 If any Participant elected to contribute less than its Proportionate Share or elected not to contribute to a Program, the amounts to be contributed by the Participants who elected to contribute their Proportionate Share shall be increased pro rata, subject to the right of any of them to elect, prior to the commencement of the Program, not to contribute more than its Proportionate Share. If one or more Participants so elect to contribute no more than its Proportionate Share and the other Participants do not elect to contribute pro rata to the resulting shortfall, the Operator shall in good faith revise the Program and Budget such that the technical objectives of the original Program are retained to the extent that is reasonably practicable given the reduced contributions to Costs. The Operator shall, within 15 days following the end of the 30-day period set out in Section 7.3, deliver to each Participant a copy of the said revised Program which, if the budget contemplates Costs of at least 80% of those contemplated in the original adopted Program, shall then be deemed for all purposes under this Agreement to be the adopted Program. If the budget for the revised Program contemplates Costs of less than 80% of those contemplated in the original adopted Program, the revised Program shall be re-submitted to the Management Committee as a draft Program pursuant to Section 7.1, and the procedure set out in Sections 7.1 to 7.4 inclusive shall be repeated.

7.5 The Operator shall be entitled to invoice each Participant:

(a)

no more frequently than monthly, for its Elected Participation Share of Exploration Costs incurred and paid by the Operator in carrying out a Program; or

(b)

not more than 60 days in advance of requirements, for an advance of that Participant’s Elected Participation Share of Exploration Costs estimated to be incurred and paid by the Operator in carrying out a Program.

Each invoice shall be signed by an officer of the Operator. Each Participant shall pay to the Operator the amount invoiced within 30 days of receipt of the invoice. If a Participant protests the correctness of an invoice it shall nevertheless be required to make the payment.

7.6 If any Participant, after having committed to contribute pursuant to Section 7.3, fails to pay an invoice within the 30-day period referred to in Section 7.5 the Operator may by

-14-

notice demand payment. If no payment is made within the period of 30 days next succeeding the receipt of the demand notice, that Participant shall be in default of this Agreement and the other Participant may, but is not obligated to, contribute the Costs that should have been paid by the defaulting Participant, the amount of which Costs shall be treated as a demand loan bearing interest at an annual rate of the Prime Rate plus 5%. If the defaulting Participant fails to repay the aforementioned loan (including all accrued interest thereon) within 10 days of demand, the Participant that is the lender (in this Section, the “Covering Participant”) may, as reasonable liquidated damages, convert any or all of the amount of shall the indebtedness (including interest) as a contribution of Costs by the Covering Participant, in which case the respective Interests of the Participants will be adjusted in accordance with Section 7.9, except that the Covering Participant will be deemed to have expended Costs equal to 200% of the amount of the indebtedness of the defaulting Participant. The Participants further acknowledge that if a Participant defaults under this Section 7.6 three times prior to any Production Notice, it shall be deemed to have forfeited its right to contribute to any further Costs under this Agreement and shall be deemed to have elected not to contribute to each Program subsequently conducted and to any Production Notice.

7.7 The Operator shall expend all monies advanced by a Participant ratably with the advances of the other Participants. If the Operator suspends or prematurely terminates a Program, any funds advanced by a Participant in excess of that Participant’s Elected Participation Share of Exploration Costs incurred prior to the suspension or premature termination shall be refunded within 60 days of the suspension or premature termination. Unless approved unanimously by the Management Committee, the Operator shall curtail the Program if it incurred Costs exceeding 110% of the amount of budgeted Exploration Costs for such Program. If the Operator fails to curtail the Program, it will be exclusively liable for the payment of all Costs incurred in excess of 110% of any budgeted Exploration Costs.

7.8 Unless otherwise directed by the Management Committee, the Operator may suspend or terminate prematurely any Program when the Operator, in good faith, considers that conditions are not suitable for the proper continuation or completion of the Program or the results obtained to that time eliminate or substantially impair the technical rationale on which the Program was based. If any Program is altered, suspended or terminated prematurely so that the Exploration Costs incurred on that Program as altered, suspended or terminated are less than 80% of the Exploration Costs set out in the adopted Program, any Participant which elected to contribute less than its Proportionate Share or elected not to contribute to that Program shall be given notice of the alteration, suspension or termination by the Operator and shall be entitled to

-15-

contribute up to its Proportionate Share of the Exploration Costs incurred on that Program by payment thereof to the Operator within 30 days after receipt of the notice, but shall not be entitled to review the results of the Program until it has made full payment. If payment is not made by that Participant within the 30 days aforesaid it shall forfeit its right to contribute to that Program without a demand for payment being required to be made thereafter by the Management Committee. If payment is made by that Participant within the 30 days as aforesaid, the Operator shall distribute the payment to the original Participants pro rata according to their respective contributions to the Program, and shall deliver to the new Participant copies of all data previously delivered to the other Participants with respect to that Program.

7.9 If a Participant elected to contribute less than its Proportionate Share or elected not to contribute to the Exploration Costs of any Program, the Interest of that Participant shall be decreased and the Interest of each Participant contributing in excess of its Proportionate Share of the Exploration Costs shall be increased so that, subject to Section 7.10, at all times during the Exploration Period the Interest of each Participant will be that percentage which is equivalent to its Exploration Costs and Prior Exploration Costs expressed as a percentage of the Exploration Costs and Prior Exploration Costs of all Participants. Notwithstanding the foregoing but subject to Section 7.10 hereof, the Participant whose Interest has been reduced (other than a party who has forfeited the right to contribute pursuant to Section 7.6) shall be entitled to receive details of and to contribute to future Programs to the extent of its then Interest. On the Operative Date, the parties’ respective Interests and Prior Exploration Costs shall be deemed to be as follows:

(a)

if Evanachan did not exercise the Second Option (as defined in the Option Agreement):

	Deemed Prior Exploration Costs	Interest
Evanachan	$4,800,000	60%
Rimfire	$3,200,000	40%

(b)

if Evanachan has exercised the Second Option (as defined in the Option Agreement):

	Deemed Prior Exploration Costs	Interest
Evanachan	$4,800,000 plus the costs incurred by Evanachan to complete the Feasibility Report to exercise the Second Option	70%
Rimfire	$2,057,143 plus 3/7 of the Costs incurred by Evanachan to complete the Feasibility Report to exercise the Second Option	30%

(c)

if Evanachan has exercised the Financing Option in accordance with the Option Agreement prior to the Operative Date:

	Deemed Prior Exploration Costs	Interest
Evanachan	$4,800,000 plus the costs incurred by Evanachan to complete the Feasibility Report to exercise the Second Option and any Maintenance Costs incurred following completion of the Feasibility Report	75%
Rimfire	$2,057,143 plus 1/3 of the Costs incurred by Evanachan to complete the Feasibility Report to exercise the Second Option and any Maintenance Costs incurred following completion of the Feasibility Report	25%

7.10 If the effect of the application of Section 7.9 is to reduce the Interest of any Participant to less than 10%, such Participant shall then be deemed to have assigned and conveyed its Interest to the Participants, if more than one then in proportion to their respective Interests, and shall be entitled to receive as its sole remuneration and benefit in consideration of that assignment and conveyance, by way of royalty, 1% of Net Smelter Returns, subject to adjustment as provided in Section 7.12, in accordance with the terms set out in Schedule C.

7.11 If the Operator fails to submit a draft Program or a revised Program by the relevant dates set out in Section 7.1 and 7.4 of this Agreement and fails to cure such default within 30 days of receiving notice of the default from a Participant, the following shall apply:

(a)

the Operator shall not be entitled to submit a draft Program or revised Program for the subject period;

(b)

any Participant other than the Operator whose Interest is more than 10% may, within 15 days following the date by which the Operator’s draft Program or revised Program was due, submit a draft Program (the “Non-Operator’s Program”) for the subject period for consideration by the Management Committee;

-16-

(c)

the Management Committee shall review the Non-Operator’s Program and, if it deems fit (the Operator not being entitled to vote with respect thereto), adopt the Non-Operator’s Program with such modifications, if any, as the Management Committee deems necessary; the adopted Program shall then be submitted to the Participants pursuant to Section 7.3;

(d)

if the Operator is a Participant and elects to contribute to the Non-Operator’s Program, it shall remain as the Operator for the duration of the Non-Operator’s Program;

(e)

if the Operator is a Participant and elects not to contribute to the Non-Operator’s Program, it shall cease to be the Operator for the duration of the Non-Operator’s Program, and the Management Committee shall appoint another Participant as Operator (the former Operator not being entitled to vote with respect thereto);

(f)

following the completion of the Non-Operator’s Program the former Operator shall, subject to the provisions of Section 5.1, automatically become the Operator.

7.12 Each of Rimfire and Evanachan hereby agrees that the maximum royalty to which it and its assigns may be collectively entitled pursuant to this Agreement is 1% of Net Smelter Returns. For example, if:

(a)

Rimfire assigns a part of its Interest to a third party pursuant to this Agreement, and

(b)

Rimfire then becomes entitled to receive 1% of Net Smelter Returns pursuant to Section 7.10 or Section 11.2(b); and

(c)

the said third party then also becomes entitled to receive a royalty of 1% of Net Smelter Returns pursuant to Section 7.10 or Section 11.2(b),

then Rimfire and such third party shall collectively be entitled to receive 1% of Net Smelter Returns, allocated between them on a proportionate basis based upon the respective Prior Exploration Costs and Exploration Costs of each of Rimfire and such third party at the time that the assignment and conveyance of its Interest took place.

-17-

8.0 FEASIBILITY REPORT

8.1 Except as provided in Section 8.2, a Feasibility Report shall only be prepared with the approval of the Management Committee. The Operator shall provide copies of the completed Feasibility Report to each of the Participants forthwith upon receipt, together with copies of all of the latest technical data and information generated or received by the Operator from the immediately preceding Program and not contained in the Feasibility Report.

8.2 Notwithstanding the provisions of Section 8.1, if a Participant (the “Proponent”) is of the view that a Feasibility Report should be prepared, such Participant shall give notice thereof to the Operator and the Operator shall call a Management Committee meeting to consider the matter. If the Management Committee fails to approve the preparation of the Feasibility Report supported by the Proponent, the Proponent may, either alone or with other Participants, at its or their sole cost, prepare a Feasibility Report. If such Feasibility Report indicates that production from the Property would be profitable to the Proponent, the Proponent shall deliver the Feasibility Report to the Operator who shall then call a Management Committee meeting to consider the Proponent’s Feasibility Report. If the Management Committee adopts the Feasibility Report, the non-contributing Participants may either pay the Proponent an amount equal to 150% of their respective proportionate costs of the preparation of the Feasibility Report, or shall suffer reduction of their respective Interests pursuant to Section 7.9. Upon the adoption by the Management Committee of the Proponent’s Feasibility Report, it shall become a Feasibility Report for all purposes hereunder.

8.3 The Participants shall meet at reasonable intervals and times to review the Feasibility Report and discuss whether the establishing and bringing of a Mine into commercial production in conformity with the Feasibility Report is feasible or desirable.

9.0 PRODUCTION NOTICE

9.1 The Operator shall call a Management Committee meeting to consider the Feasibility Report for a date no sooner than three months and no later than six months (unless otherwise agreed by the parties) after the Feasibility Report was provided to each of the Participants.

9.2 The Management Committee shall consider the Feasibility Report prepared and may by Special Majority, approve the Feasibility Report, with such modifications, if any, as it considers necessary or desirable, together with an estimate of Construction Costs. If a Feasibility Report is approved as aforesaid the Management Committee shall forthwith cause a Production

-18-

Notice to be given to each of the Participants by the Operator stating that the Management Committee has approved that a Mine be established and brought into production in conformity with the Feasibility Report and estimated Construction Costs as so approved.

10.0 FINANCING OPTION

10.1 Within 75 days of receiving a Production Notice, Rimfire may request that Evanachan arrange project financing required for Mine Costs (the “Financing Option”), in return for an additional undivided 5% legal and beneficial Interest in the Property on the terms and conditions described in this Section 10.0.

10.2 In order to exercise the Financing Option, Evanachan shall:

(a)

have delivered the Production Notice to Rimfire; and

(b)

arrange project financing for the Mine Costs as set out in the Feasibility Report, with Rimfire’s portion of the project financing to be recovered solely from 80% of Rimfire’s share of free cash flow from the Mining Operations and which Evanachan will use best efforts to arrange (for both Participants based on prevailing market conditions).

10.3 Upon Evanachan having arranged project financing, Evanachan shall have exercised the Financing Option and Rimfire shall transfer to Evanachan an additional undivided 5% legal and beneficial Interest in the Property, free and clear of any liens, charge, encumbrances or underlying agreements or interests, subject only to the applicable terms of the Underlying Royalties. In addition, the respective Costs attributed to each Participant shall be adjusted so that, subject to Section 7.10, the Interest of each Participant will be that percentage which is equivalent to its Costs expressed as a percentage of the Costs of all Participants.

10.4 If Evanachan fails to arrange project financing and does not exercise the Financing Option, Evanachan will retain its then current Interest.

11.0 ELECTION TO CONTRIBUTE

11.1 Unless Evanachan has exercised the Financing Option contemplated in Section 10.0, each Participant with an Interest may, within 120 days of the receipt of the Production Notice, give the Operator notice committing to contribute its Proportionate Share of Construction Costs. A Participant which fails to give that notice within the 120-day period shall be deemed to have elected not to contribute to Construction Costs.

-19-

11.2 If any Participant elects not to contribute to Construction Costs that Participant, subject to its rights under Section 11.4, shall forfeit the right to contribute to any further Costs under this Agreement, and those Participants which elected to contribute as aforesaid may thereupon elect to increase their contribution to Construction Costs, if more than one Participant then in proportion to their respective Interests, by the amount which any Participant has declined to contribute. If elections are made so that Construction Costs are fully committed:

(a)

the Interest of each Participant shall be increased and that of each non-Participant shall be decreased as Costs are incurred so that the Interest of each Participant at all times is that percentage which is equivalent to:

(i)

the sum of its Exploration Costs, its Prior Exploration Costs and its contribution to Construction Costs;

divided by:

(ii)

the sum of the total Exploration Costs, total Prior Exploration Costs and the total Construction Costs of all the Participants;

multiplied by:

(iii)

100;

(b)

then, at the Completion Date, each non-Participant shall be deemed to have assigned and conveyed its Interest to the Participants, if more than one then in proportion to their respective Interests, and shall be entitled to receive as its sole remuneration and benefit in consideration of that assignment and conveyance, by way of royalty, subject to adjustment as provided in Section 7.12, 1% of Net Smelter Returns, as and when available, which is equivalent to the Interest, calculated at the Completion Date;

(c)

each Participant shall severally calculate and cause to be paid to each non-Participant any Net Smelter Returns derived from the Property in the manner provided in Schedule C; and

(d)

notwithstanding the provisions of Sections 11.2(b) and (c), if the effect of the application of Section 11.2(a) reduces any party’s Interest to less than 1% it shall forfeit its Interest to the Participants, if more than one then in proportion to their respective Interests, and that party shall have no further right or interest under this Agreement.

-20-

11.3 If, after the operation of Section 11.2, Construction Costs are not fully committed the Production Notice shall be deemed to be withdrawn, and shall not be resubmitted, either in the same or a revised form, for a period of at least six months following such withdrawal.

11.4 If, after the operation of Section 11.2, Construction Costs are fully committed, the Participants shall diligently proceed with bringing a Mine into production in substantial conformity with the Feasibility Report. If the Participants fail to commence the implementation of the Feasibility Report within 12 months of Construction Costs being fully committed, for reasons other than general economic conditions in the mining industry, any party which forfeited the right to contribute to Construction Costs pursuant to Section 11.2 shall have the right, exercisable in the 30 days following the expiration of such 12-month period, to reacquire from the Participants not less than all of its Interest as last held, by paying its Proportionate Share of Construction Costs incurred to the end of such 12-month period (together with interest at the Prime Rate plus 3%) to the Participants in proportion to their respective Interests.

11.5 During the 12-month period referred to in Section 11.4, neither the Operator nor any Participant shall be obliged to provide any non-Participant with the results of any work carried out on the Property, the Participants’ sole obligation during such period being to provide any non-Participant, on the written request of such non-Participant made only once during the said 12 months, with a summary of the nature of the work carried out and the total Costs thereof.

12.0 OPERATOR’S FEE

12.1 The Operator may charge the following sums in return for its head office overhead functions which are not charged directly:

(a)

with respect to Programs 10% of all Costs (excluding Maintenance Costs);

(b)

with respect to Construction: 4% of all other such Costs (excluding Maintenance Costs); and

(c)

subsequent to the Completion Date: 2.5% of all Operating Costs(excluding Maintenance Costs).

13.0 MINE FINANCING

13.1 Subject to Section 10.0, the contributions of the Participants toward the Mine Costs shall be individually and separately provided by them.

-21-

13.2 Subject to the Financing Option not being exercised or fulfilled pursuant to Section 10.0, each Participant hereby covenants and agrees with the other to cooperate fully in connection with any project financing for the Mine Costs which is presented on reasonable commercial terms for projects of a similar nature, size and financial risk and to hold its Interest in the Property free and clear of all liens, charges and encumbrances including any floating charge (except liens for taxes not yet due and other inchoate liens arising from operations on the Property being contested in good faith) and each Participant shall, if so required by the terms of such project financing, issue to any lender providing such financing, bonds, debentures or other security instruments charging its Interest in the Property, inter alia, by way of a specific first mortgage and charge limited to its Interest in the Property. No such project financing shall require either Participant to give any guarantee to any third Participant on behalf of the other Participant, to be jointly and severally liable for the repayment of such financing or to give security to any lenders in respect of such financing in an amount greater than its Interest in the Property.

13.3 If Evanachan exercises the Financing Option or if the Participants jointly arrange for financing of Mine Costs as contemplated by Section 13.2, the Operator shall have the sole right, on behalf of all Participants having an Interest in the Property, the Assets and any Mine, to pledge, mortgage, charge or otherwise encumber all or a portion of the Property, the Assets or any Mine in order to secure moneys borrowed and used to finance the exploration, development and the placing of the Property into commercial production, provided that the agreement provides that the pledgee, mortgagee, holder of the charge or encumbrance (in this Section 13.0 called the “Chargee”) shall hold the same subject to the provisions of this Agreement and that if the Chargee realizes upon any of its security it will comply with this Agreement. If requested by the Operator, any party hereto, shall pledge, mortgage or charge or otherwise encumber all or a portion of its Interest to facilitate the financing of exploration, development or the placing of the Property into commercial production. The Agreement between the party hereto, as borrower, and the Chargee shall contain specific provisions to the same effect as the provisions of this Section. Subject to the forgoing, a party hereto does not have the right to pledge, mortgage, charge or otherwise encumber all or a portion of its Interest.

13.4 If a joint financing for the Mine Costs is not arranged as contemplated in Section 13.3, then for the purpose of financing its share of Mine Costs a Participant may, at any time, mortgage, charge or otherwise encumber the whole or any part of its interest in the Property but only upon the condition that the Chargee first enters into a written agreement with

-22-

the other Participant in form satisfactory to counsel for such other Participant, binding upon the Chargee, to the effect that:

(a)

the Chargee will not enter into possession or institute any proceedings for foreclosure or partition of the encumbering Participant’s interest in the Property and that such encumbrance shall be subject to the provisions of this Agreement;

(b)

the Chargee’s remedies under the encumbrance shall be limited to the sale of the whole (but only of the whole), of the encumbering Participant’s interest in the Property to the other Participant in accordance with Section 34.0, or failing such disposition, at a public auction to be held after 90 days’ prior notice to the other Participant, such sale to be subject to the purchaser entering into a written agreement with the other Participant whereby such purchaser assumes all obligations of the encumbering Participant under the terms of this Agreement; and

(c)

if the interest of a Participant in the Property is forfeited, the right of such Participant to act as Operator for the Property will cease.

14.0 CONSTRUCTION

14.1 Subject to Sections 11.2 and 11.3, the Management Committee shall cause the Operator to, and the Operator shall, proceed with Construction with all reasonable dispatch after a Production Notice has been given. Construction shall be substantially in accordance with the Feasibility Report subject to any variations proposed in the Production Notice, and subject also to the right of the Management Committee to cause such other reasonable variations in Construction to be made as the Management Committee, by Special Majority, deems necessary and advisable.

15.0 OPERATION OF THE MINE

15.1 Commencing on the Completion Date, all Mining Operations shall be planned and conducted and all estimates, reports and statements shall be prepared and made on the basis of a calendar year.

-23-

15.2 With the exception of the year in which the Completion Date occurs, an Operating Plan for each calendar year shall be submitted by the Operator to the Participants not later than November 1 in the year immediately preceding the calendar year to which the Operating Plan relates. Each Operating Plan shall contain the following:

(a)

a description of the proposed Mining Operations;

(b)

a detailed estimate of all Mine Costs plus a reasonable allowance for contingencies;

(c)

an estimate of the quantity and quality of the ore to be mined and the concentrates or metals or other products and by-products to be produced; and

(d)

such other facts as may be necessary to reasonably illustrate the results intended to be achieved by the Operating Plan.

Upon request of any Participant the Operator shall meet with that Participant to discuss the Operating Plan and shall provide such additional or supplemental information as that Participant may reasonably require with respect thereto.

15.3 The Management Committee shall make a decision regarding each Operating Plan, with such changes as it deems necessary, by November 30 in the year immediately preceding the calendar year to which the Operating Plan relates; provided, however, that the Management Committee, by Special Majority, may from time to time and any time amend any Operating Plan.

15.4 The Operator shall include in the estimate of Mine Costs referred to in Section 15.2(b) hereof the establishment of a trust or escrow fund providing for the reasonably estimated costs of satisfying continuing obligations that may remain after the permanent termination of Mining Operations, in excess of amounts actually expended. Such continuing obligations are or will be incurred as a result of the Joint Operation and shall include such things as monitoring, stabilization, reclamation or restoration obligations, severance and other employee benefit costs and all other obligations incurred or imposed as a result of the Joint Operation which continue or arise after the permanent termination of Mining Operations and the termination of this Agreement and settlement of all accounts. The payment of such continuing obligations shall be made on the basis of units of production, and shall be in amounts reasonably estimated to provide over the lifetime of proven and probable reserves funds adequate to pay for

-24-

such reclamation and long term care and monitoring. The Participants shall contribute to the trust or escrow fund cash (or provide letters of credit or other forms of security readily convertible to cash in form approved by the Management Committee). The amount contributed from time to time for the satisfaction of such continuing obligations shall be classified as Costs hereunder but shall be segregated into a separate account.

15.5 If the Interest of a Participant is converted to a Net Smelter Returns royalty interest pursuant to Section 7.10 or 11.2(b), the Participant whose Interest was converted shall remain liable for its share of all amounts chargeable to it in respect of the Property as of the date of such conversion as well as all liabilities and obligations relating to the Property in an amount equal to its Interest at the time such liabilities and obligations arose. If the remaining Participants require it to do so, the party whose Interest was so converted shall secure to the satisfaction of the remaining Participants its share of the Costs of reclamation of the surface lands to the Property and other environmental rehabilitation as may be required, such share to be determined on the basis of the Interest of the party whose Interest was converted to a Net Smelter Returns royalty interest at the time the events giving rise to such liabilities occurred.

16.0 PAYMENT OF MINE COSTS

16.1 The Operator may invoice each Participant, from time to time, for that Participant’s Proportionate Share of Construction Costs or Operating Costs incurred to the date of the invoice, or at the beginning of each month for an advance equal to that Participant’s Proportionate Share of the estimated cash disbursements to be made during the month. Each Participant shall pay its Proportionate Share of the Construction Costs or Operating Costs or the estimated cash disbursements aforesaid to the Operator within 30 days after receipt of the invoice. If the payment or advance requested is not so made, the amount of the payment or advance shall bear interest calculated monthly not in advance from the 30^th day after the date of receipt of the invoice thereof by that Participant at a rate equivalent to the weighted average Prime Rate for the month plus 3% until paid. The Operator shall have a lien on each Participant’s Interest in order to secure that payment or advance together with interest which has accrued thereon.

16.2 If any Participant fails to pay an invoice contemplated in Section 16.1 within the 30-day period aforesaid, the Operator may, by notice, demand payment. If no payment is made within 30 days of the Operator’s demand notice, the Operator may, without limiting its other rights at law, enforce the lien created by Section 16.1 by taking possession of all or any part of

-25-

that Participant’s Interest. The Operator may sell and dispose of the Interest which it has so taken into its possession by:

(a)

first offering that Interest to the other Participants, if more than one then in proportion to the respective Interests of the Participants who wish to accept that offer, for that price which is the fair market value stated in the average of two appraisals obtained by the Operator from independent, well recognized appraisers competent in the appraisal of mining properties; and

(b)

if the Participants have not purchased all or part of that Interest as aforesaid, then by selling the balance, if any, either in whole or in part or in separate parcels at public auction or by private tender (the Participants being entitled to bid) at a time and on whatever terms the Operator shall arrange, having first given notice to the defaulting Participant of the time and place of the sale.

As a condition of the sale as contemplated in Section 16.2(b), the purchaser shall agree to be bound by this Agreement and, prior to acquiring the Interest, shall deliver notice to that effect to the parties, in form acceptable to the Operator. The proceeds of the sale shall be applied by the Operator in payment of the amount due from the defaulting Participant and interest as aforesaid, and the balance remaining, if any, shall be paid to the defaulting Participant after deducting reasonable costs of the sale. Any sale or disposal made as aforesaid shall be a perpetual bar both at law and in equity by the defaulting Participant and its successors and assigns against all other Participants.

17.0 DISTRIBUTION IN KIND

17.1 It is expressly intended that, upon implementation of any Production Notice hereunder, the association of the Participants hereto shall be limited to the efficient production of Minerals from the Property and related activities, and that each of the Participants shall be entitled to use, dispose of or otherwise deal with its Proportionate Share of Minerals as it sees fit. Each Participant shall take in kind, f.o.b. truck or railcar on the Property, and separately dispose of its Proportionate Share of the Minerals produced from the Mine. From the time of delivery, each Participant shall have ownership of and title to its Proportionate Share of Minerals separate from, and not as tenant in common with, the other Participants, and shall bear all risk of loss of Minerals. Extra costs and expenses incurred by reason of the Participants taking in kind and making separate dispositions shall be paid by each Participant directly and not through the Operator or Management Committee.

-26-

17.2 Each Participant shall construct, operate and maintain, all at its own cost and expense, any and all facilities which may be necessary to receive and store and dispose of its Proportionate Share of the Minerals at the rate the same are produced.

17.3 If a Participant has not made the necessary arrangements to take in kind and store its share of production as aforesaid the Operator shall, at the sole cost and risk of that Participant store, in any location where it will not interfere with Mining Operations, the production owned by that Participant. The Operator and the other Participants shall be under no responsibility with respect thereto. All of the Costs involved in arranging and providing storage shall be billed directly to, and be the sole responsibility of the Participant whose share of production is so stored. The Operator’s charges for such assistance and any other related matters shall be billed directly to and be the sole responsibility of the Participant. All such ▇▇▇▇▇▇▇▇ shall be subject to the provisions of Sections 16.1 and 16.2 hereof.

18.0 SURRENDER OF INTEREST

18.1 Any party not in default hereunder may, at any time upon notice, surrender its entire Interest to the other parties by giving those parties notice of surrender. The notice of surrender shall:

(a)

indicate a date for surrender not less than three months after the date on which the notice is given; and

(b)

contain an undertaking that the surrendering party will:

(i)

satisfy its Proportionate Share, based on its then Interest, of all obligations and liabilities which arose at any time prior to the date of surrender;

(ii)

if the Operator has not included in Mine Costs the costs of continuing obligations as set out in Section 15.4 hereof, pay on the date of surrender its reasonably estimated Proportionate Share, based on the surrendering party’s then Interest, of the Costs of rehabilitating the Mine site and of reclamation based on the Mining Operations completed as at the date of surrender; and

(iii)

will hold in confidence, for a period of two years from the date of surrender, all information and data which it acquired pursuant to this Agreement.

-27-

18.2 Upon the surrender of its entire Interest as contemplated in Section 18.1 and upon delivery of a release in writing, in form acceptable to counsel for the Operator, releasing the other parties from all claims and demands hereunder, the surrendering party shall be relieved of all obligations or liabilities hereunder except for those which arose or accrued or were accruing due on or before the date of the surrender.

18.3 A party to whom a notice of surrender has been given as contemplated in Section 18.1 may elect, by notice within 90 days to the party which first gave the notice to accept the surrender, in which case Sections 18.1 and 18.2 shall apply, or to join in the surrender. If all of the parties join in the surrender the Joint Operation shall be terminated in accordance with Section 19.0

19.0 TERMINATION OF MINING OPERATIONS

19.1 The Operator may, at any time subsequent to the Completion Date, on at least 30 days’ notice to all Participants, recommend that the Management Committee approve that the Mining Operations be suspended. The Operator’s recommendation shall include a plan and budget (in this Section 19.0 called the “Mine Maintenance Plan”), in reasonable detail, of the activities to be performed to maintain the Assets and Property during the period of suspension and the Costs to be incurred. The Management Committee may, by Special Majority, at any time subsequent to the Completion Date, cause the Operator to suspend Mining Operations in accordance with the Operator’s recommendation with such changes to the Mine Maintenance Plan as the Management Committee deems necessary. The Participants shall be committed to contribute their Proportionate Share of the Costs incurred in connection with the Mine Maintenance Plan. The Management Committee, by Special Majority, may cause Mining Operations to be resumed at any time.

19.2 The Operator may, at any time following a period of at least 90 days during which Mining Operations have been suspended, upon at least 30 days’ notice to all Participants, or in the events described in Section 19.1, recommend that the Management Committee approve the permanent termination of Mining Operations. The Operator’s recommendation shall include a plan and budget (in this Section 19.0 called the “Mine Closure Plan”), in reasonable detail, of the activities to be performed to close the Mine and reclaim and rehabilitate the Property, as required by applicable law, regulation or contract by reason of this Agreement. The Management Committee may, by unanimous approval of the representatives of all Participants, approve the Operator’s recommendation with such changes to the Mine Closure Plan as the Management Committee deems necessary.

-28-

19.3 If the Management Committee approves the Operator’s recommendation as aforesaid, it shall cause the Operator to:

(a)

implement the Mine Closure Plan, whereupon the Participants shall be committed to pay, in proportion to their respective Interests, such Costs as may be required to implement that Mine Closure Plan;

(b)

remove, sell and dispose of such Assets as may reasonably be removed and disposed of profitably and such other Assets as the Operator may be required to remove pursuant to applicable environmental and mining laws; and

(c)

sell, abandon or otherwise dispose of the Assets and the Property.

The disposal price for the Assets and the Property shall be the best price reasonably obtainable and the net revenues, if any, from the removal and sale shall be credited to the Participants in proportion to their respective Interests.

19.4 If the Management Committee does not approve the Operator’s recommendation contemplated in Section 19.2, the Operator shall maintain Mining Operations in accordance with the Mine Maintenance Plan as pursuant to Section 19.1.

20.0 THE PROPERTY

20.1 Title to the Property shall be held in the name of the Operator in trust for the parties in proportion to their respective Interests as adjusted from time to time. Each of the parties shall have the right to receive, forthwith upon making demand therefor from the Operator, such documents as it may reasonably require to confirm its Interest.

20.2 This Agreement, or a memorandum of this Agreement, shall, upon the written request of any party, be recorded in the office of any governmental agency so requested, in order to give notice to third parties of the respective interests of the parties in the Property and this Agreement. Each party hereby covenants and agrees with the requesting party to execute such documents as may be necessary to perfect such recording.

21.0 AREA OF COMMON INTEREST

21.1 The area of common interest shall be deemed to comprise any mineral interest staked after the date of the Option Agreement and located wholly or partly within one mile of the

-29-

boundaries of the Property as they existed on the date of the Option Agreement and as shown on the map attached in Schedule A to this Agreement (the “Area of Interest”).

21.2 If at any time during the subsistence of this Agreement any party or the Affiliate of any party (in this Section only called in each case the “Acquiring Party”) stakes any mining claim, licence, lease, grant, concession, permit, patent, or other mineral property located wholly or partly within the Area of Interest referred to in Section 21.1, the Acquiring Party shall forthwith give notice to the other parties of that staking, the total cost thereof and all details in the possession of that party with respect to the details of the staking, the nature of the property and the known mineralization.

21.3 The Management Committee (the representative of the Acquiring Party not being entitled to vote with respect thereto) may, within 30 days of receipt of the Acquiring Party’s notice, elect, by notice to the Acquiring Party, to require that the mineral properties and the right or interest acquired be included in and thereafter form part of the Property for all purposes of this Agreement.

21.4 If the election aforesaid is made, all the other parties shall reimburse the Acquiring Party for that portion of the cost of staking which is equivalent to their respective Interests.

21.5 If the Management Committee does not make the election aforesaid within that period of 30 days, the right or interest acquired shall not form part of the Property and the Acquiring Party shall be solely entitled thereto.

21.6 Notwithstanding Section 6.4(e), the Operator shall be entitled, at any time and from time to time to surrender all or any part of the Property or to permit the same to lapse, but only upon first either obtaining the unanimous consent of the Management Committee, or giving 60 days’ notice of its intention to do so to the other parties. In this latter event, the parties, other than the Operator, shall be entitled to receive from the Operator, on request prior to the date of the surrender or lapse, pro rata in accordance with their respective Interests, a conveyance of that portion of the Property intended for surrender or lapse, together with copies of any plans, assay maps, diamond drill records and factual engineering data in the Operator’s possession and relevant thereto. Any part of the Property so acquired shall cease to be subject to this Agreement and shall not be subject to Section 21.2. Any part of the Property which has not been so acquired by any of the parties shall remain subject to Section 21.2.

34.0 ASSIGNMENT ¾ RIGHT OF FIRST REFUSAL

34.1 If a party (hereinafter in this Section referred to as the “Owner”):

receives a bona fide offer from an independent third party (the “Proposed Purchaser”) dealing at arm’s length with the Owner to purchase all or any part all of the Owner’s Interest or its interest in this Agreement (which for certainty shall include the Owner’s right to receive Net Smelter Returns), which offer the Owner desires to accept; or

-35-

(b)

if the Owner intends to sell all or any part of its Interest or its interest in this Agreement,

the provisions of Section 34.2 shall apply.

34.2 The Owner shall first offer (the “Offer”) such interest in writing to the other party upon terms no less favourable than those offered by the Proposed Purchaser or intended to be offered by the Owner, as the case may be. The Offer shall specify the price and terms and conditions of such sale, the name of the Proposed Purchaser (which term shall, in the case of an intended offer by the Owner, mean the person or persons to whom the Owner intends to offer its interest) and, if the offer received by the Owner from the Proposed Purchaser provides for any consideration payable to the Owner otherwise than in cash, the Offer shall include the Owner’s good faith estimate of the cash equivalent of the non-cash consideration. If within a period of 60 days of the receipt of the Offer, the other party notifies the Owner in writing that it will accept the same, the Owner shall be bound to sell such interest to the other party (subject as hereinafter provided with respect to price) on the terms and conditions of the Offer. If the Offer so accepted by the other party contains the Owner’s good faith estimate of the cash equivalent consideration as aforesaid, and if the other party disagrees with the Owner’s best estimate, the other party shall so notify the Owner at the time of acceptance and the other party shall, in such notice, specify what it considers, in good faith, the fair cash equivalent to be and the resulting total purchase price. If the other party so notifies the Owner, the acceptance by the other party shall be effective and binding upon the Owner and the other party and the cash equivalent of any such non-cash consideration shall be determined by binding arbitration under the Commercial Arbitration Act (British Columbia) and shall be payable by the other party, subject to prepayment as hereinafter provided, within 60 days following its determination by arbitration. The other party shall in such case pay to the Owner, against receipt of an absolute transfer of clear and unencumbered title to the interest of the Owner being sold, the total purchase price which it specified in its notice to the Owner and such amount shall be credited to the amount determined following arbitration of the cash equivalent of any non-cash consideration. If the other party fails to notify the Owner before the expiration of the time limited therefor that it will purchase the interest offered, the Owner may sell and transfer such interest to the Proposed Purchaser at the price and on the terms and conditions specified in the Offer for a period of 60 days, provided that the terms of this Section shall again apply to such interest if the sale to the Proposed Purchaser is not completed within the said 60 days. Any sale hereunder shall be conditional

-36-

upon the Proposed Purchaser delivering a written undertaking to the other party, in form and content satisfactory to its counsel, to be bound by the terms and conditions of this Agreement.

34.3 For greater certainty, nothing contained in the provisions of this Section 34.0 shall prevent any party from entering into any corporate reorganization, merger, amalgamation, takeover bid, plan of arrangement, or any other such corporate transaction which has the effect of, directly or indirectly, selling, assigning, transferring, or otherwise disposing of all or a part of the Interest to a Proposed Purchaser.

35.0 SUCCESSORS AND ASSIGNS

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

36.0 GOVERNING LAW

36.1 This Agreement shall be governed by and interpreted in accordance with the laws of the Province of British Columbia.
