- 14 -

(a)	the Offeror shall promptly notify the Offeree of its intentions. The Notice shall state the price in cash or cash equivalent in the form of marketable securities (the “Purchase Price”) and all other pertinent terms and conditions of the intended transfer.

8.2

Section 8.1 shall not apply to the following:

(a)	a transfer by the Offeror of all or any part of its interest in this Agreement and the Property to an Affiliate; provided that:

	(i)	the transferee remains an Affiliate indefinitely thereafter;

	(ii)	the subsequent transfer of Control of such Affiliate, other than to an Affiliate of the original Offeror, whether through the issuance or transfer of shares in the capital of the Affiliate or otherwise (such that it no longer conforms to the definition of an Affiliate) shall be subject to Section 8.1;

2.3 Relationship of parties.

(1) After the Participation Date the rights and obligations of the Participants shall be, in each case, several, and shall not be or be construed to be either joint or joint and several. Nothing contained in this agreement shall, except to the extent specifically authorized under this agreement, be deemed to constitute a Participant a partner, an agent or legal representative of any other party. It is intended that this agreement shall not create the relationship of a partnership between the Participants and that no act done by any Participant pursuant to the provisions of this agreement shall operate to create such a relationship.

(2) Claims by third parties arising out of the activities of the Joint Venture shall be borne by the Participants in proportion to their ownership interest in and to the Property, and the other party or parties to this agreement shall have a right of contribution therefor against one another.

(3) The right of each party to mine and market production from other sources in competition with the other parties and of each Participant to market its share of any Mineral Product in competition with any other Participant is confirmed.

2.5 Continuing Interests. Each Participant shall have an Interest as is determined in accordance with the provisions of this agreement, and any legal title to any of the Assets or Property held by any Participant shall be subject to this agreement.

2.6 Term. Unless earlier terminated by agreement of all parties having an Interest or as a result of one party acquiring a 100% Interest and the other party a 2% Net Smelter interest (see Appendix I), the joint operation and this agreement shall remain in full force and effect for so long as any party has any right, title or interest in the Property. Termination of the agreement shall not, however, relieve any party from any obligations accrued but unsatisfied, nor from its obligations with respect to rehabilitation of the Mine site and reclamation.

3. Interests of Participants

3.1 Initial Interests. On the Participation Date, Candev shall have an undivided 80% Interest and Yale shall have an undivided 20% Interest, subject to the reservation of a 2% net smelter return royalty as provided for and defined in the Option Agreement. Thereafter, each Participant shall have an Interest as is determined from time to time in accordance with the provisions of this paragraph.

3.2 Deemed expenditures. On the Participation Date the Optionor and the Optionee will each have made or be deemed to have made the following expenditures:

Party:	Deemed Expenditures:	Deemed Percentage Interest:
Yale	$ 203,750	20 %
Candev	$ 815,000	80 %
Total:	$ 1,018,750	100 %

3.3 Adjustment of Interests. Subsequent to the Participation Date, the respective Interests of the Participants shall be determined from time to time as being equal to the product obtained by multiplying 100% by a fraction of which the numerator is the amount of that party's contributions to Costs after the Participation Date plus that party's deemed expenditure, and the denominator is the amount of all contributions to Costs made subsequent to the Participation Date by all Participants plus the deemed expenditures by both parties.

3.4 Net Smelter Interest. The respective Interests of the Participants shall not change so long as they each contribute their respective Cost Share of every Program as set out in paragraph 7. At any time after a Participant loses its right to contribute to a Program its respective Interest shall be reduced in accordance with the formula set out in paragraph 3.3. If, as a result of that calculation, the Interest of a Participant is reduced to below 10 %, the Interest of that party shall be converted to a 2 % Net Smelter Interest, as set out in paragraph 8, and thereafter the party whose Interest has been reduced shall be deemed not to be a party to this agreement and shall have no further rights under this agreement or in respect of the Property.

Upon agreement of the parties, 50% of the Net Smelter Interest (or a total of 1%) may be purchased by the other party for $1,000,000 and the second 50% (or a total of 1%) for $1,500,000.

A Participant may from time to time revoke in writing the appointment of its representative or alternate representative, and appoint in writing a substitute.

4.3 Meetings. The Operator shall call a Management Committee meeting at least once every twelve months and, in any event, within fourteen days of being requested to do so by any representative.

4.4 Notice of meetings. The Operator shall give notice, specifying the time and place in Canada of, and the agenda for, the meeting, to all Participants, representatives and alternate representatives at least seven days before the time appointed for the meeting.

4.5 Waiver of notice. Notice of a meeting shall not be required if one representative of each party is present at a meeting and unanimously agree on the agenda.

If a quorum is present at the meeting, the Management Committee shall be competent to exercise all of the authorities, powers and discretions bestowed on it under this agreement. No business other than the election of a chairperson, if any, and the adjournment or termination of the meeting shall be transacted at any meeting unless a quorum is present at the commencement of the meeting but the quorum need not be present throughout the meeting. If within half an hour from the time appointed for a meeting, a quorum is not present, the meeting shall, at the election of those representatives who are present:

	(a)	be dissolved; or

	(b)	be adjourned to the same place but on a date and at a time, to be fixed by the chairperson of the meeting before the adjournment, which shall be not less than fourteen days following the date for which the meeting was called.

Notice of the adjourned meeting shall be given to the representatives of all parties immediately after the adjournment of the meeting. If at the adjourned meeting, a quorum is not present within half an hour from the time appointed, the representative or representatives present and entitled to attend and vote at the meeting, shall be a quorum even if only one person is present.

7.2 Preparation of Programs. Immediately after the Participation Date and thereafter on or before November 15^th each year or within ninety days of completion of the last Program, the Operator shall prepare and submit to the Management Committee a draft Program for the next calendar year. The draft Program shall contain a statement in reasonable detail of the proposed Mining Operations and estimates of all Costs to be incurred.

7.3 Review of Program. The Management Committee shall review the Program prepared and, if it deems fit, adopt the Program with those 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 Costs and any Costs so incurred shall be deemed to be included in the Program, as adopted.

7.4 Submission of Program. The Operator shall immediately submit the adopted Program to the parties. Each party may, within thirty days of receipt of the Program, give written notice to the Operator committing to contribute its proportionate share of the Costs on that Program. A party which fails to give that notice within the thirty-day period shall be deemed to have elected not to contribute. If any party elected or is deemed to have elected not to contribute to a Program, the other Participant may give notice in writing to the Operator stating that it will contribute all expenditures under or pursuant to the Program and the Operator will proceed with that Program and thereafter the Interests of the parties shall be adjusted in accordance with paragraph 3.3. The Operator will not proceed with any Program which is not fully subscribed.

7.5 Commencement of Program. If the Participants elect to contribute their respective Cost Share of a Program, or if a Participant gives notice that it will contribute all expenditures under a Program, the Operator will proceed with the Program.

7.6 Mandatory expenditures. Notwithstanding paragraph 7.1, if, in any year in which there is no Program adopted pursuant to this agreement, circumstances are such that the Operator must incur costs in order to maintain tenure to the Property, to satisfy contractual obligations or obligations imposed by law, to prevent waste or to protect life and property (in this paragraph called "non-discretionary costs"), the Operator shall immediately propose a program (in this paragraph called the "mandatory program") to incur those non-discretionary costs and provide each party with one copy of it. The mandatory program shall be deemed to be approved and each of the parties shall be obligated to contribute to the non-discretionary costs incurred in proportion to their respective Interest within thirty days of receipt of the Operator's invoice; failing which contribution paragraph 7.9 shall apply.

7.7 Liability for payment. An election by a Participant to contribute to a Program shall make that Participant liable to pay its Cost Share or all of the Costs if it has so elected, actually incurred under or pursuant to the Program including Program Overruns, as defined, of up to but

not exceeding 10%.

7.8 Invoicing of expenditures.

(1) The Operator shall be entitled to invoice each Participant:

	(a)	no more frequently than monthly, for its proportionate share of Costs incurred and paid by the Operator; or

	(b)	thirty days in advance of requirements, but in any event not to exceed the requirements for the next calendar quarter, for an advance of that Participant's proportionate share of Costs.

(2) Each invoice shall be signed by some responsible official of the Operator. Each Participant shall pay to the Operator the amount invoiced, within thirty days of receipt of the invoice. If a Participant protests the correctness of an invoice it shall nevertheless be required to make the payment.

7.9. Failure to pay. If any Participant fails to pay its proportionate share of, or all of the Costs if it has so elected, within the thirty-day period referred to in paragraph 7.8 the Operator may by notice demand payment. If no payment is made within the period of thirty days next succeeding the receipt of the demand notice the other Participant may elect to increase their contributions to satisfy the shortfall, or the Operator shall curtail or abandon the Program, and the defaulting Participant shall be deemed to have forfeited its right to contribute to any further Costs under this agreement and it shall not receive notice of and shall be deemed to have elected not to contribute to each Program subsequently conducted and to a Production Notice and accordingly shall have its Interest reduced in the manner contemplated in paragraph 7.12.

7.10 Program Overruns. If it appears that Costs will exceed by greater than 10% those estimated under a Program, the Operator shall immediately give written notice to the Participants contributing to that Program outlining the nature and extent of the additional costs and expenses (the "Program Overruns"). If Program Overruns are not approved by the Participants contributing to that Program, the Operator shall the right to curtail or abandon the Program.

7.11 Suspension of Program. If any Program is altered, suspended or terminated prematurely so that the Costs incurred on that Program as altered, suspended or terminated are less than 80% of the Costs originally proposed, any party which elected not to contribute to that Program shall be given notice of the alteration, suspension or termination by the Operator and shall, subject to paragraph 7.9, be entitled to contribute its proportionate share of the Costs incurred on that Program by payment thereof to the Operator within thirty days after receipt of the notice. If payment is not made by that party within thirty days 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.

7.12 Adjustment of Interests. If a party elects not to contribute to the 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 Costs shall be increased so that, subject to paragraph 8.1, the Interest of each party will be that percentage calculated as set out in paragraph 3.3. Except in the events described in paragraph 7.9 or if that party's Interest is assigned or conveyed as contemplated in paragraph 8.1, the party whose Interest has been reduced shall be entitled to receive details of and contribute to future Programs to the extent of its then Interest.

7.13 Funds spent ratably. The Operator shall expend all moneys 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 Costs incurred prior to the suspension or premature termination shall be refunded immediately.

7.14 Election not to contribute. Notwithstanding that a Participant has or is deemed to have elected not to contribute to a Program under paragraph 7.4, it shall nevertheless, subject to paragraphs 7.9 and 8.1, be entitled to elect to participate in and contribute to future Programs under this agreement.

8. Non-participation

8.1 Effect of non-participation. If a party (in this paragraph called the "Assigning Party") has its Interest reduced, at any time to less than 10 % as a result of the operation of paragraph 7.12, the Assigning Party 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, in consideration of that assignment and conveyance, shall be entitled to receive as its sole remuneration and benefit, a royalty, as and when available, in the amount of 2% of the Net Smelter Interest. On such assignment, the Assigning Party shall cease to have any further right or Interest under this Agreement. Each Participant shall severally calculate and cause to be paid to the Assigning Party that portion of any of the Net Profits derived from the Property to which the Assigning Party is entitled in the manner provided in Schedule 1 to this agreement.

9. Financing

9.1 Responsibility of Participants. The contributions of the Participants toward the Costs shall be individually and separately provided by them.

9.2 Encumbrances. Solely in order to secure loans to meet their respective contributions toward the Costs, the Participants shall each be entitled to pledge, mortgage, charge or otherwise encumber, as security for financing their respective contributions, the Property and Assets to the extent of their respective Interests; provided, however, that security shall not be given by any party unless the proposed pledgee, mortgagee, holder of the charge or encumbrance (the "Chargee") first undertakes in writing with all the other Participants, in form reasonably satisfactory to counsel for the Operator and binding on the Chargee, that:

(a)

the Chargee will not enter into possession or institute any proceedings for foreclosure or partition of an encumbering Participant's Interest or interest in the Property and that that security 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 and interest in the Assets held under that security to the other Participants, if more than one then in proportion to their respective Interests at that time or, with their unanimous consent, to any one of them, or failing any sale as mentioned, by a sale at a public auction to be held after ninety days' prior notice to the other Participants; provided, however, that as a condition of the purchase, the purchaser shall agree with the parties that it:

	(i)	assumes all the obligation of the encumbering Participant in connection with this agreement, and

	(ii)	will be bound by this agreement, and,

prior to completing the purchase, delivers to the parties notice to that effect in writing, in form reasonably satisfactory to counsel for the Operator.

10. Disposition of production

10.1 Allocation of production. For any period after the commencement of Commercial Production and provided that each Participant has paid to the Operator its respective Cost Share for that period, each Participant shall take in kind and separately dispose of Mineral Products in the ratio of each Participant's respective Interest.

10.2 Value of Mineral Products. For purposes of determining the value of Mineral Products taken in kind pursuant to paragraph 10.1, each Participant's share of Mineral Products shall be valued at the time of delivery to the Participants at a value equal to that received by Candev for its share of the Mineral Products after deduction of:

	(a)	all costs of transporting Mineral Products, including insurance, from the Property to the place of delivery designated by the purchaser of the Mineral Products;

	(b)	a reasonable charge for marketing Mineral Products as is consistent with generally accepted industry marketing practices; and

	(c)	all taxes (other than income taxes), royalties or other charges or imposts provided for pursuant to any law or legal obligation imposed by any government if paid by the Participant in connection with the disposition of Mineral Products taken in kind.

10.4 Extra expenditure. Any extra expenditure incurred by reason of the taking in kind or separate disposition by a Participant of its proportionate share of Mineral Products shall be borne by that Participant and that Participant shall be required to construct, operate and maintain, at its own expense, any and all facilities which may be necessary to receive, store and dispose of its share of Mineral Products.

10.5 Operator's authority. If any Participant fails to make the necessary arrangements to take in kind or separately dispose of its proportionate share of Mineral Products, the Operator as agent may purchase for its own account or sell that share, subject to the right of the Participant owning the share to revoke at will the Operator's authority under this paragraph in respect of Mineral Products not then purchased by the Operator or committed for sale to others, and the Operator shall be entitled to deduct from the sale proceeds all costs of or related to marketing the Mineral Products as is consistent with generally accepted industry marketing practices including, without limitation, transportation, storage, commissions and discounts but all contracts of sale executed by the Operator for a Participant's share of Mineral Products shall be only for reasonable periods of time as are consistent with the minimum needs of the industry under the circumstances and in no event shall any contract be for a period in excess of one year.

12. Suspension and termination of Mining Operations

12.1 Suspension of operations. The Operator may, at any time subsequent to the Participation Date, on at least thirty days' notice to all Participants, recommend that the Management Committee approve that Mining Operations be suspended. The Operator's recommendation shall include a plan and budget (in this paragraph 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, 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 may cause Mining Operations to be resumed at any time.

	(b)	sell that Interest to an affiliate of the Disposing Party; provided, however, that the Disposing Party shall provide a guarantee to the other parties, in form reasonably satisfactory to counsel for the Operator, guaranteeing the obligations of the affiliate under this agreement and provided, further, that the sale to the affiliate shall be subject to the affiliate entering into an agreement with the remaining Participants whereby it agrees to be bound by the provisions of this agreement.

21.2 Offer to sell. A Disposing Party will, prior to disposing of the Interest other than to an affiliate, first offer to sell the Interest to the Participants for a cash consideration and on other terms and conditions as the Disposing Party deems fit. If, within thirty days of the Disposing Party's offer to sell, the Participants elect not to purchase the Interest on those terms and conditions the Disposing Party will be free to dispose of that Interest to a third party at any time within six months of the Participants' election but only for a cash consideration, or for some consideration other than cash, provided that the fair cash equivalent of any non-cash consideration be equal to or greater than the cash consideration stated in the Disposing Party's offer to sell to the Participants, and on no more favourable terms and conditions as the offer to sell to the Participants; provided, however, that the sale of the Interest to the third party shall be subject to the third party entering into an agreement with the Participants whereby it agrees to be bound by the provisions of this agreement. Any Interest not disposed of by the Disposing Party as mentioned will remain subject to the provisions of this paragraph.

21.3 Acquisition of Interest. On the Participants or a third party acquiring all or a portion of the Disposing Party's Interest, the Participants or the third party will be deemed to have acquired a corresponding portion of the Disposing Party's Costs. The third party will be entitled to all the rights and benefits accruing, and will be subject to the same duties and

obligations attributable to them, to the Interest which it has purchased from the Disposing Party including the right to participate in any further Programs and Costs and the right to having its Interest increased or reduced in the same manner as the Disposing Party in the event the third party does not participate in the Programs and Costs.

Appendix 1

To the Joint Venture Agreement between

Candev Resources Ltd. ("Candev") and

Yale Ventures Corp. ("Yale")

NET SMELTER INTEREST

This being Appendix 1 to that Joint Venture Agreement between Yale and Candev dated for reference (-)

1.1

Income and Expenses

Net Profits shall be calculated by deducting from the Gross Revenue (as defined below) realized (or deemed to be realized), such costs and expenses attributable to Exploration, Development, Mining, the marketing of Products and other Operations as would be deductible under generally accepted accounting principles and practices consistently applied, including without limitation:

	(a)	All costs and expenses of replacing, expanding, modifying, altering or changing from time to time the Mining facilities. Costs and expenses of improvements (such as haulage ways or mill facilities) that are also used in connection with workings other than the Properties shall be charged to the Properties only in the proportion that their use in connection with the Properties bears to their total use;

	(b)	Ad valorem real property and unsecured personal property taxes, and all taxes, other than income taxes, applicable to Mining of the Properties, including without limitation all mining taxes, sales taxes, severance taxes, license fees and governmental levies of a similar nature;

	(c)	Allowance for overhead in accordance with Section 6;

	(d)	All expenses incurred relative to the sale of Products, including an allowance for commissions at rates, which are normal and customary in the industry;

	(e)	All amounts payable to the remaining Participant during Mining pursuant to any applicable operating or similar agreement in force with respect thereto;

	(f)	The actual cost of investment under the Agreement but prior to beginning of Mining, which shall include all expenditures for Exploration and Development of the Properties incurred by the non-withdrawing Participant both prior and subsequent to the withdrawing Participant acquiring a Net Profits interest;

	(g)	Interest on monies borrowed or advanced for costs and expenses, but in no event in excess of the maximum permitted by law;

	(h)	An allowance for reasonable working capital and inventory;

	(i)	Costs of funding the Environmental Compliance Fund as provided in Section 6;

	(j)	Actual costs of Operations; and

	(k)	Rental, royalty, production, and purchase payments.

For purposes hereof, the term “Gross Revenue” shall mean the sum of (i) gross receipts from sale of Products, less any charges for sampling, assaying, or penalties; (ii) gross receipts from the sale or other disposition of Assets; (iii) insurance proceeds; (iv) compensation for expropriation of Assets; and (v) judgment proceeds. Gross receipts for sale of Products shall be determined by multiplying spot prices for Products as quoted by the New York Spot Market on the date of a sale of Products.

It is intended that the remaining Participant shall recoup from Gross Revenue all of its on-going contributions for Exploration, Development, Mining, Expansion and Modification and marketing Products before any Net Profits are distributed to any person holding a Net Profits interest. No deduction shall be made for income taxes, depreciation, amortization or depletion. If in any year after the beginning of Mining of the Properties an operating loss relative thereto is incurred, the amount thereof shall be considered as and be included with outstanding costs and expenses and carried forward in determining Net Profits for subsequent periods. If Products are processed by the remaining Participant, or are sold to an Affiliate of the remaining Participant, then, for purposes of calculating Net Profits, such Products shall be deemed conclusively to have been sold at a price equal to fair market value to an arm’s length purchaser FOB the concentrator for the Properties, and Net Profits relative thereto shall be calculated without reference to any profits or losses attributable to smelting or refining.

1.2

Payment of Net Profits

Payments of Net Profits shall commence in the calendar quarter following the calendar quarter in which Net Profits are first realized, and shall be made forty-five (45) days following the end of each calendar quarter during which Net Profits are realized, and shall be subject to adjustment, if required, at the end of each calendar year. The recipient of such Net Profits payments shall have the right to audit such payments following receipt of each payment by giving notice to the remaining Participant and by conducting such audit in accordance with Section Error! Reference source not found. of the Agreement. Costs of such an audit shall be borne by the holder of the Net Profits interest described herein.

1.4

All words and terms used herein have the same meaning as in the Agreement.
