8. EXPLORATION PROGRAMS

8.1 Draft Programs submitted by the Operator to the Management Committee shall contain a statement in reasonable detail of the proposed Program and estimates of all Exploration Costs to be incurred.

8.2 The Management Committee shall review the draft Program prepared and, if it deems fit, adopt the same 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% of a Program budget (the “Overrun”)and any Costs so incurred shall be deemed to be included in the Program. In the event of a Cost overrun of greater than 10% of the Program budget, the Operator shall pay all Costs in excess of the Overrun unless such Costs are unanimously approved by the Management Committee.

8.3 The Operator shall forthwith submit the approved Program to the Parties. Each Party may, within 60 days of receipt of the Program, give notice to the Operator committing to contribute its Proportionate Share of the Exploration Costs on that Program. A Party which fails to give notice within the 60 day period shall be deemed to have elected not to contribute.

8.4 If any party elects or is deemed to have elected not to contribute to an approved Program the amounts to be contributed by the Participants who elected to contribute to that Program shall be increased pro rata, subject to the right of any of them to elect not to contribute more than the amount initially committed by them. If a Participant elects not to contribute more than the amount initially committed the Operator may elect not to proceed with the approved Program or may prepare an amended Program and the provisions of this Article shall apply to such amended Program.

8.5 The Operator shall be entitled to invoice each Participant:

	(a)	no more frequently than monthly for its Proportionate Share of Exploration Costs incurred and paid by the Operator; or

	(b)	in advance of requirements but not more than 30 days for an advance of that Participant's Proportionate Share of Exploration Costs.

Each invoice shall be signed by some responsible official 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 subject to later adjustment if such protest is sustained.

8.6 If after electing to participate any Participant (the "Defaulting Party") fails to pay its Proportionate Share within the 30 day period referred to in Paragraph 8.5 the Operator may by notice demand payment. If no payment is made within the period of 30 days next succeeding the receipt of the demand notice the Interest of the Defaulting Party shall be deemed to be less than 20% and that interest will be converted to a 5% Net Profits Royalty to be calculated and paid in accordance with Appendix II hereto, and that Party shall have no further Interest. The Interests of the other Parties shall be increased pro rata.

8.7 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 Proportionate Share of Exploration Costs incurred prior to the suspension or premature termination shall be refunded forthwith.

8.8 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 originally proposed, any Party which elected or which is deemed to have elected not to contribute its Proportionate Share of the Exploration Costs incurred on that Program shall be given notice of the alteration, suspension or termination by the Operator and shall be entitled to contribute 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. If payment is not made by that Party within the 30 days aforesaid it shall, without a demand for payment being required to be made thereafter by the Management Committee, forfeit its right to contribute to that Program.

8.9 If a Party elects or is deemed to have elected not to contribute to the Exploration Costs of any Program the Interest of that Party 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 at all times during the Exploration Period the Interest of each Party will be equal to its Exploration Costs and Prior Exploration Costs expressed as a percentage of the Exploration Costs and Prior Exploration Costs of all Parties. The party whose Interest has been reduced shall be entitled to receive details of and to contribute to future Programs to the extent of its then Interest.

8.10 If a Party's Interest is reduced to 20% or less, that Interest will be converted to a 5% Net Profits Royalty to be calculated and paid in accordance with Appendix II hereto, and that Party shall have no further Interest. The Interests of the other Parties shall be increased pro rata.

8.11 If the Operator fails to submit a draft Program for an Operating Year by December 31 of the year preceding such Operating Year:

(a)

the Operator shall not be entitled to submit a draft Program for the Operating Year;

	(b)	the other Party, and if there is more than one, the Party with the greatest Interest, may submit a draft Program (the "Non-Operator's Program") for the Operating Year for consideration by the Management Committee;

	(c)	the Management Committee shall review the Non-Operator's draft Program and, if it deems fit (the Operator not being entitled to vote with respect thereto), adopt the Program with such modifications, if any, as the Management Committee deems necessary and the adopted Program shall then be submitted to the parties according to this Article;

	(d)	if the Operator is a Party and elects not to contribute to the Program it shall cease to be the Operator and the Management Committee shall appoint a new Operator (the former Operator not being entitled to vote with respect thereto).

8.12 If the Management Committee for any reason fails to adopt a Program for an Operating Year by December 31 of the preceding year, the Operator shall, subject to direction to the contrary by the Management Committee and the receipt of the necessary funds, carry out such work and make such disbursements as to meet the minimum requirements to maintain the Property in good standing.

9. FEASIBILITY REPORT

9.1 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 Parties forthwith upon receipt.

9.2 The Management Committee shall meet at reasonable intervals and times to review the Feasibility Report and discuss whether the establishing of a Mine and bringing the Property into Commercial Production in accordance with the Feasibility Report is feasible or desirable.

9.3 If the Operator has not provided copies of a completed Feasibility Report to each of the Parties with an Interest by the fifth anniversary of this Agreement, any Party whose Interest is not less than 20% and if there is more than one, the Party with the greatest Interest, may prepare a Feasibility Report at its own expense (the "Non-Operator's Feasibility Report") and submit it to the Management Committee.

10. PRODUCTION NOTICE

10.1 The Operator shall call a meeting of the Management Committee to consider the Feasibility Report for a date no sooner than six months after the Feasibility Report was provided to each of the Parties.

10.2 The Management Committee shall consider each Feasibility Report prepared and may approve any Feasibility Report with such modifications, if any, as it considers necessary or desirable. Such approval by the Management Committee must be given by Participants holding aggregate Interests of not less than 51%. If the Feasibility Report is a Non-Operator's Feasibility Report the Operator is not entitled to vote with respect to the approval thereof. If a Feasibility Report is approved as aforesaid the Management Committee shall forthwith cause a Production Notice to be given to each of the Parties with an Interest by the Operator stating that the Management Committee intends to establish and bring a Mine into production pursuant to the Feasibility Report as so approved.

11. ELECTION TO CONTRIBUTE

11.1 Each Party with an Interest may, within 120 days of receipt of the Production Notice, give the Operator notice committing to contribute its Proportionate Share of the Mine Costs. A Party which fails to give notice within the 120 day period shall be deemed to have elected not to contribute.

11.2 If any such Party fails to give such notice, that Party (a "non-Participant") shall forfeit the right to contribute to Mine Costs and shall suffer dilution and conversion of its Interest as provided in this paragraph. Those Parties which elected to contribute as aforesaid may thereupon elect to increase their contribution to the Mine Costs, if more than one Party then in proportion to their respective Interests, by the amount which any Party has declined to contribute. If elections are made so that Mine Costs are fully committed the Interest of each Participant shall be increased and that of each non-Participant shall be decreased so that the Interest of each Party at all times is equal to:

	(a)	the sum of its Exploration Costs, its Prior Exploration Costs and its contribution to Mine Costs;

		divided by

	(b)	the sum of the total Exploration Costs, total Prior Exploration Costs and the total Mine Costs of all the Parties;

		multiplied by

	(c)	100.

If any Party's Interest is thereby less than 20% it shall forfeit its Interest to the Participants, if more than one then in proportion to their respective Interests, and that Party shall be entitled to receive as its sole remuneration and benefit in consideration of that assignment and conveyance, a 5% Net Profits Royalty calculated in accordance with Appendix II. Each Participant shall severally cause to be paid to each non-Participant any Net Profits Royalty derived from the Property in the manner provided in Appendix II.

11.3 If Mine Costs are not fully committed the Production Notice shall be deemed to be withdrawn.

11.4 If Mine Costs are fully committed, the Operator shall diligently proceed to implement the Feasibility Report in accordance with normal standards in the mining industry. If the Operator fails to so implement the Feasibility Report within 12 months of the issuance of the Production Notice for reasons other than general economic conditions in the mining industry, any Party which forfeited the right to contribute to Mine Costs pursuant to section 11.2 shall have the right, exercisable during the 30 days following the expiration of such 12 month period, to re-acquire from the Participants all of its Interest as last held, by paying its Proportionate Share of Mine Costs together with interest at the Prime Rate plus 2% to the Participants in proportion to their Interests.

11.5 During the 12 month period referred to in section 11.4 the Participants shall not be obligated 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, but only once during the said 12 months, with a summary of the nature of the work carried out and the total Costs thereof.

14. OPERATION OF THE MINE

14.1 Commencing with 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 an Operating Year.

14.2 With the exception of the first Operating Year an operating plan for each Operating Year shall be submitted by the Operator to the Participants not later than the end of the third quarter in the year immediately preceding the Operating Year to which the Operating Plan relates. Each Operating Plan shall contain the following:

	(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 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,

and 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. PAYMENT OF MINE COSTS

15.1 The Operator may invoice each Participant, from time to time, for that Participant's Proportionate Share of Mine 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 Mine 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 30th 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 2% per annum 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.

15.2 If any Participant (in this section 15.2 called a "Defaulting Participant") fails to pay an invoice within the 30 day period as 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 15.1 by taking possession of all or any part of the Defaulting 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 non-Defaulting Participants, and if there is 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 lower of two appraisals obtained by the Operator from independent, well recognized appraisers competent in the appraisal of mining properties; and

	(b)	if the non-Defaulting 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 (neither the Participants nor the Defaulting Participant 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 subsection 15.2(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 and the Operator.

16. DISTRIBUTION IN KIND

16.1 It is expressly intended that, upon implementation of any Production Notice hereunder, the association of the parties shall be limited to the efficient production of Minerals from the Property and that each of the parties 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. 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.

16.2 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 they are produced.

16.3 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 parties 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 an be the sole responsibility of the Participant. All such billings shall be subject mutatis mutandis to the provisions of sections 15.1 and 15.2 thereof.

	(iii)	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.

17.2 Upon the surrender of its entire Interest as contemplated in section 17.1 and upon delivery of a release in writing in form acceptable to counsel for the Operator releasing the other parties from all claims and demand 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.

17.3 A Party to whom a notice of surrender has been given may elect, by notice within 90 days to the Party which first gave the notice, to accept the surrender, in which case the provisions of this Article shall apply, or to join in the surrender.

NET PROFITS ROYALTY

Pursuant to the attached Agreement, a party (the "Royalty Holder") may be entitled to a royalty equal to a percentage of Net Profits (the "Net Profits Royalty"). The Party or Parties who are not a Royalty Holder (the "Owner") shall be entitled to a 100% beneficial interest in the Property subject to the Net Profits Royalty.

	(d)	Post-production Capital Expenditures;

	(e)	Interest Charges; and

	(f)	Reserve Charges.

2. The Operator shall apply Net Profits first to reduce the amounts debited to the Royalty Account. While there is any debit balance in the Royalty Account, the Owner shall retain all Product or Net Profits (in proportion to their Interests if more than one Owner). Whenever the Royalty Account shows no debits, Net Profits in an amount equal to the credit balance in the Royalty Account shall be distributed to the Royalty Holder in an amount equal to the applicable Net Profits Royalty, and the balance to the Owner.

3. The Operator shall debit or credit amounts to the Royalty Account, whichever is applicable, on a monthly basis and distribution of Net Profits shall be made on an interim basis within 20 days of the end of each month. A final settlement of the distribution of Net Profits shall be made within 90 days of the end of each calendar year. The Owner shall be entitled to deduct any overpayment of Net Profits as revealed in the annual calculation for purposes of the final settlement from future payments due to the Royalty Holder. Any underpayment shall be paid by the Owner to the Royalty Holder forthwith.

4. The Owner shall at all times maintain adequate records which shall be made available to the Royalty Holder in order that the Royalty Holder may verify the correctness of any entries in the Royalty Account or in the determination of Net Profits. The Owner shall utilize methods of weighing and sampling ore which are generally accepted within the industry.

5. The terms which are defined in the Agreement shall have the same defined meanings in this Appendix, the provisions of this Appendix are subject to the provisions of the Agreement and the following words, phrases and expressions shall have the following meanings:

	(b)	Net Profits means, in any month after the Completion Date, the amount by which Revenue exceeds Operating Costs.

	(c)	Operating Costs means all costs of Commercial Production categorized as "operating" costs by generally accepted accounting practice including all taxes, royalties and other levies except for federal and provincial corporate income taxes but not including any charges for depreciation, depletion or amortization. Operating Costs shall also include a reasonable charge for administration and management not to exceed 10% of all other Operating Costs.

	(d)	Operating Losses means the amount by which Operating Costs exceed Revenue in any month after the commencement of Commercial Production.

	(e)	Post-production Capital Expenditures means all expenditures made by the Owner after the Completion Date to acquire or construct assets having a useful life of more than one year or on development or expansion of a mine or other production facilities the cost of which would be charged on a unit of production basis in accordance with generally accepted accounting principles.

	(f)	Pre-production Expenditures means all money provided and spent by the Owner on the Property prior to the commencement of Commercial Production including, without limiting the generality of the foregoing, all money provided and spent by the Owner exploring, developing and equipping the Property for production, completing Feasibility Reports, maintaining the Property in good standing, constructing all facilities necessary to commence Commercial Production on the Property, constructing or acquiring infrastructure or facilities off of the Property but required for Commercial Production, and on making any other expenditures related to the achievement of Commercial Production.

	(g)	Reserve Charges means an amount to be established by estimating the cost of rehabilitation which will have to be spent after Commercial Production has terminated and a portion of that cost will be charged monthly to the Royalty Account over a reasonable period of time commencing no sooner than five years prior to the termination of Commercial Production.
