8.1 The Optionee will have the right at any time prior to earning the 70% Interest to give notice to the Optionor terminating the Option and this Agreement. If the Optionee gives such notice of termination or, subject to §5.6, §5.7 and §14.1, if the Optionee fails to incur the Work Costs and consideration referred to in §5.1(d) on or before the dates referred to therein, then the Option and this Agreement will terminate and the Optionee will, subject to the provisions of Part 3, Part 6 and Part 11, and subject to §8.3 have no further rights or interest in the Property and no further obligations or liabilities to the Optionor.

PART 9

FORMATION AND OPERATION OF JOINT VENTURE

Formation of Joint Venture

9.1 Effective as of the Earn-In Date, the Optionee and the Optionor will participate in a joint venture (the “Joint Venture”) by entering into a formal joint venture agreement (the “Joint Venture Agreement”) for the purpose of further exploration and development work on the Property and if warranted, the operation of one or more mines on the Property.

Participating Interests

9.2 The participating interests of the parties at the time the Joint Venture is formed will be:

Optionee	70%
Optionor	30%

Each party will be responsible for payment of its proportionate share (based on its participating interest) of the operating and capital costs of the Joint Venture’s operations, including reclamation and remediation obligations and any security required therefore.

Management Committee

9.3 Upon formation of the Joint Venture, a management committee (the “Management Committee”), formed by members from each party and holding voting rights in accordance with each party’s participating interest, will be established which will make all decisions, on a simple majority vote, which are required to be made by the Joint Venture parties with respect to the Joint Venture’s operation, including but not limited to the supervision and approval of exploration, development, construction, mining, milling, processing, treatment operations and related operations conducted in respect of the Property. The Management Committee will have the authority to establish its own rules on how meetings of the Management Committee will be called and conducted.

Operator

9.4 The Operator will be subject to the direction and control of the Management Committee. The Optionee will have the right to be the Operator of the Joint Venture and to manage and operate the exploration, feasibility study, mine development and mining phases of the project during the term of the Joint Venture, provided that the Optionee’s participating interest in the Joint Venture is at least fifty percent (50%). If the Optionee holds less than a fifty percent (50%) participating interest, the Management Committee may appoint a new Operator.

- 21 -

Overhead Costs

9.5 The Operator will be entitled to charge the Joint Venture an amount for general overhead and administrative costs and management fees equal to:

(a) for exploration, including the preparation of the Preliminary Economic Assessment, five percent (5%) of all Work Costs incurred under each contract with a third party involving an expenditure in excess of $100,000, and seven and one-half percent (7.5%) of all other Work Costs incurred;

(b) for development and construction, five percent (5%) of all Work Costs up to the aggregate amount of $100,000, and three and one-half percent (3.5%) of Work Costs exceeding such aggregate amount; and

excluding in each case the amount of the overhead charge fixed under this §9.5.

The parties intend that the Operator will not lose or profit by reason of acting as Operator of the Joint Venture. The Operator’s rates for general overhead and administrative costs and management fees will be reviewed annually by the Management Committee, which may make such amendments as may be necessary or desirable to achieve the parties’ intention.

Contracts with Operator

9.6 The Operator and any Affiliate of the Operator may enter into contracts with the Joint Venture, provided that at the time of formation of any such contract the terms thereof, including the allocation of revenues, costs, obligations and liabilities are fair and reasonable, and that any charges made by the Operator or its Affiliates to the Joint Venture do not exceed the fair market value therefore.

Accounting Procedures

9.7 The Operator will maintain or cause to be maintained the accounts for the Joint Venture, to the extent and in such detail and at such places as the Management Committee may determine, such books and records pertaining to the Joint Venture and to the costs and expenses thereof and the performance of the Operator hereunder, and to the receipt and disposition of proceeds from any joint sales, as will properly reflect, in accordance with International Financial Reporting Standards to the extent applicable and not in conflict with the provisions hereof, all transactions of the Operator in relation to the operation of the Joint Venture and the performance of the Operator’s duties hereunder and all costs paid by the Operator in the performance thereof and for which it will seek reimbursement, all of which books and records will be made available to the other party and the Management Committee, upon reasonable notice and at all reasonable times, for inspection, audit and reproduction. As soon as possible after the close of each fiscal year of the Operator, all the books and accounts of the Operator relating to the operation of the Joint Venture for such fiscal year will be audited by the auditors for the Optionee or such other auditors as the Management Committee may determine at the expense of the Joint Venture and copies of the report of the auditors will be sent promptly to each party. Any claim against the Operator relating to any transactions during the period covered by such audit will be made within two (2) years after such audit.

- 22 -

Programs and Budgets

9.8 The Operator will propose the work programs and budgets following the formation of the Joint Venture in accordance with the instructions of the Management Committee. Each party will have thirty (30) days from the date of receipt of a program to notify the Operator as to whether it will participate at its interest level or whether it will not participate. The participating interest of a party which elects not to participate will be proportionately diluted in accordance with the dilution formula set out in §9.9. A party which fails to so notify the Operator within the time required will be deemed to have elected to participate in the work program at its interest level. A party’s right not to participate in a work program and be diluted as aforesaid may only be exercised prior to a production decision, subject to §9.12. A party which elects not to participate in a program will not be subject to dilution to the extent that the expenditures under such program exceed one hundred fifteen percent (115%) of the budget for such program. If a party fails to pay after electing to participate that party will suffer an accelerated dilution of one-hundred fifty percent (150%) of the monies not paid. The Joint Venture Agreement shall provide that monies required for a work program must be paid no later than thirty days (30) prior to commencement of a work program.

Dilution

9.9 The dilution formula will be as follows:

percentage participating interest of party Y = (A + B) x 100
C

where:

A = deemed expenditures of party Y

B = actual expenditures of party Y

C = total expenditures (deemed and actual) of all parties

Deemed expenditures are assigned a value based on work done by the Optionee in order to earn its participating interest. Thus, the deemed expenditures for the parties will be as follows:

	Participating interests of the parties:	Their deemed expenditures upon formation of the Joint Venture will be:

	Optionee 70%	$1,850,000

	Optionor 30%	$792,857

For the purposes of calculating B and C above, actual expenditures are those expenditures made by a party after formation of the Joint Venture, provided that such actual expenditures will exclude costs made or incurred and included in Work Costs prior to the day that the Management Committee gives notice to the parties of the formation of the Joint Venture but paid subsequent to formation of the Joint Venture.

- 23 -

Excess Work Costs

9.10 Any Work Costs made or incurred by the Optionee in excess of the Work Costs required to earn its interest in the Property will be credited to Optionee’s contribution to the first work program after formation of the Joint Venture and will not automatically dilute the participating interest of the Optionor on formation.

Royalty Interest

9.11 If any party is diluted to a ten percent (10%) or lower participating interest, that party will be deemed to have waived the opportunity to participate in future work programs, whether in exploration, development or production, and to have converted its participating interest to a two percent (2%) Net Smelter Return, to be determined and paid as set out in Schedule “B” hereto.

Production Decision

9.12 For ninety (90) days following a positive production decision, each party to the Joint Venture will have the right to elect to participate in the financing in proportion to its then current participating interest in the Joint Venture. If a party does not elect to participate in the financing, or is unsuccessful in raising its proportionate share of the financing, then the other party may arrange all the financing required and if it does so, the participating interest of the party which has not provided its share of the financing will be converted to a two percent (2%) Net Smelter Return, to be determined and paid as provided in Schedule “B” hereto.

Reclamation Fund

9.13 Upon Commencement of Commercial Production, a reclamation fund will be established to which the parties will be obliged to contribute in accordance with their participating interests. The reclamation fund will be in an amount determined by the Management Committee from time to time. The Operator will in its reasonable discretion accept security in lieu of receiving such payment in cash. The reclamation fund need not be maintained if one party acquires all of the other party’s participating interest in the Joint Venture.

Default in Funding

9.14 If a party to the Joint Venture defaults in its obligation to contribute to any program and budget or to make any other required contribution, the other party may at its election make such contribution on behalf of the defaulting party (a “cover payment”). The cover payment will constitute indebtedness due from the defaulting party to the party making the cover payment and will be payable on demand, will bear interest at the prime rate of the Bank of Canada plus 10 percent (10%) per annum and will be secured by the defaulting party’s right, title and interest in the Property and all production therefrom.

- 24 -

The party making the cover payment will have the right to sell in any commercially reasonable manner the defaulting party’s share of products of any mine developed on the Property until the cover payment and accrued interest thereon have been paid in full, or may at any time prior to such payment in full at its election:

(a) adjust the parties’ respective participating interests pursuant to §9.9;

(b) sell the defaulting party’s right, title and interest in the Property to a third party in a manner provided by applicable law or otherwise in a commercially reasonable manner and upon reasonable notice; or

(c) purchase for its own account all right, title and interest of the defaulting party in the Property at the fair market value thereof.

Taking in Kind

9.15 Except as otherwise expressly provided in §9.14, each party will be entitled to take in kind and separately dispose of its share of products of any mine developed on the Property in accordance with its participating interest. Any expenditure incurred in the taking in kind of products by a party will be borne by it. The division of products for the purposes of this provision will be conducted in a fair and equitable manner.

Failure to Enter into Joint Venture Agreement

9.16 If for any reason the Joint Venture Agreement is not settled, executed and delivered, this Agreement, containing the above Joint Venture terms, will remain binding on the parties and will continue to govern their relationship and operations on the Property.

If, however, any such violation should inadvertently occur, the parties hereby agree that a court will reform that provision in such a way as to approximate most closely the intent of the parties within the limits permissible under such rules.

Resale Restrictions

16.15 All Shares issued by the Optionee to the Optionor pursuant to this Agreement will be subject to such resale restrictions as may be imposed by applicable securities law and the Exchange.

Change in Capitalization

16.16 If the Optionee undertakes a change in capitalization affecting its Shares, (other than the concurrent private placement) such as subdivision, consolidation or reclassification of the Shares or other relevant changes in Shares, including any adjustment arising from a merger, acquisition or plan of arrangement, such proportionate adjustments, if any, appropriate to reflect such change will be made by the Optionor with respect to the number of Shares which may be issued by the Optionee to the Optionor hereunder.

SCHEDULE “B”

NET SMELTER ROYALTY

This is Schedule “B” to the Option and Joint Venture Agreement between Lake Victoria Mining Company, Inc. Otterburn Ventures Inc. dated as of the Execution Date (the “Agreement”). All capitalized terms under in this Schedule “B” but not otherwise defined have the meanings ascribed thereto in the Agreement.

1.	The Royalty Interest which may be payable to the Optionor s (the "Payee") by the Optionee (the "Payor") pursuant to Subsection 8.11 of the Agreement will be two (2%) percent of the Net Smelter Revenue (as hereinafter defined) and will be calculated and paid to the Payee by the Payor in accordance with the terms of this Schedule "B". Terms having defined meanings in the Agreement and used herein will have the same meanings in this Schedule as assigned to them in the Agreement unless otherwise specified or the context otherwise requires.

2.	The Net Smelter Revenue will be calculated on a calendar quarterly basis and will, subject to paragraph 8 of this Schedule "B", be equal to Gross Revenue less Permissible Deductions for such quarter.

3.	The following words will have the following meanings:

	(a)	"Gross Revenue" means the aggregate of the following amounts received in each quarterly period:

		(i)	the revenue received by the Payor from arm's length purchasers of all Product,

		(ii)	the fair market value of all Product sold by the Payor in such quarter to persons not dealing at arm's length with the Payor, and

		(iii)	any proceeds of insurance on Product; and

	(b)	"Permissible Deductions" means the aggregate of the following charges (to the extent that they are not deducted by any purchaser in computing payment) that are paid in each quarterly period:

		(i)	sales charges levied by any sales agent on the sale of Product,

		(ii)	transportation costs for Product from the Claims to the place of beneficiation, processing or treatment and thence to the place of delivery of Product to a purchaser thereof, including shipping, freight, handling and forwarding expenses,

		(iii)	all costs, expenses and charges of any nature whatsoever which are either paid or incurred by the Payor in connection with refinement or beneficiation of Product after leaving the Property, including all weighing, sampling, assaying and representation costs, metal losses, any umpire charges, and any penalties charged by the processor, refinery or smelter, and

		(iv)	all insurance costs on Product, and any government royalties, production taxes, severance taxes and sales and other taxes levied on Ore, Product or on the production or value thereof (other than any Federal or Provincial taxes levied on the income or profit of the Payor),

- 2 -

	provided that where a cost or expense otherwise constituting a Permissible Deduction is incurred by the Payor in a transaction with a party with whom it is not dealing at arm's length (as that term is defined in the Income Tax Act (Canada)), such cost or expense may be deducted, but only as to the lesser of the actual cost incurred by the Payor or the fair market value thereof, calculated at the time of such transaction and under all the circumstances thereof.

4.	The Payor shall have the right to commingle with ores from the Property, ore produced from other properties, provided that prior to such commingling, the Payor shall adopt and employ reasonable practices and procedures for weighing, determination of moisture content, sampling and assaying, as well as utilize reasonable accurate recovery factors in order to determine the amounts of products derived from, or attributable to Ore mined and produced from the Property. The Payor shall maintain accurate records of the results of such sampling, weighing and analysis as pertaining to ore mined and produced from the Property.

5.	The Royalty Interest will be calculated and paid within thirty (30) days after the end of each calendar quarter if reasonably possible. Smelter settlement sheets, if any, and a statement setting forth calculations in sufficient detail to show the payment's derivation (the "Statement") must be submitted with the payment.

6.	All Royalty Interest payments will be considered final and in full satisfaction of all obligations of the Payor with respect thereto, unless the Payee delivers to the Payor a written notice (the "Objection Notice") describing and setting forth a specific objection to the calculation thereof within sixty (60) days after receipt by the Payee of the Statement. If the Payee objects to a particular Statement as herein provided, the Payee will, for a period of sixty (60) days after the Payor's receipt of such Objection Notice, have the right, upon reasonable notice and at reasonable times, to have the Payor's accounts and records relating to the calculation of the payment in question audited by the auditors of the Payor. If such audit determines that there has been a deficiency or an excess in the payment made to the Payee, such deficiency or excess will be resolved by adjusting the next monthly Royalty Interest payment due hereunder. The Payee will pay all the costs and expenses of such audit unless a deficiency of three (3%) percent or more of the amount due is determined to exist. The Payor will pay the cost and expenses of such audit if a deficiency of three (3%) percent or more of the amount due is determined to exist. All books and records used and kept by the Payor to calculate the Royalty Interest due hereunder will be kept in accordance with Canadian generally accepted accounting principles. Failure on the part of the Payee to make claim against the Payor for adjustment in such sixty (60) day period by delivery of an Objection Notice will conclusively establish the correctness and sufficiency of the Statement and payment on account of the Royalty Interest for such quarter.

7.	At the election of the Payee made in writing at least ninety (90) days prior to the Closing on account of the Royalty Interest (which election may not be rescinded without the consent of the Payor, such consent not to be unreasonably withheld) the Payee may elect to receive the Royalty interest in kind, provided that any extra costs or expenses incurred by the Payor as a result of such election and payment of the Royalty Interest in kind will be for the account of the Payee and will be due on demand.

8.	All profits and losses resulting from the Payor engaging any commodity futures trading, option trading, metals trading, transactions with respect to Product which is a precious metal (collectively, "Hedging Transactions") are specifically excluded from calculations of the Royalty Interest pursuant to this Schedule "B" (it being the intent of the parties that the Payor will have the unrestricted right to market and sell Product to third parties in any manner it chooses and that the Payee will not have any right to participate in such marketing activities or to share in any profits or losses therefrom).

- 3 -

	All Hedging Transactions by the Payor and all profits or losses associated therewith, if any, will be solely for the Payor's account, irrespective of whether or not Product is delivered in fulfillment of such obligations. The amount of Net Smelter Revenue derived from all Product subject to Hedging Transactions by the Payor will be determined pursuant to the provisions of this paragraph 8 and not paragraph 2. As to precious metals subject to Hedging Transactions by the Payor, Net Smelter Revenue will be determined without reference to Hedging Transactions and will be determined by using, for gold, the monthly average price of gold, which will be calculated by dividing the sum of all London Bullion Market Association P.M. Gold Fix prices reported for the calendar month in question by the number of days for which such prices were quoted, and for silver, the monthly average price of silver, which will be calculated by dividing the sum of all New York Commodity Exchange ("COMEX") prices for silver quoted by and at the closing of COMEX reported for the calendar month in question by the number of days for which such prices were quoted, less, in each case, an amount reasonably equivalent to the deductions permitted by paragraph 3 (b). Any Product subject to Hedging Transactions will be deemed to be sold, and revenues received therefrom, only on the date of final settlement of the amount of refined Product allocated to the account of the Payor by a third party refinery in respect of such transactions.

9.	If the Royalty Interest becomes payable to two or more parties, those parties will appoint, and will deliver to the Payor a document executed by all of those parties appointing, a single agent or trustee of all such parties to whom the Payor will make all payments on account of the Royalty Interest. The Payor will have no responsibility as to the division of the Royalty Interest payments among such parties, and if the Payor makes a payment or payments on account of the Royalty Interest in accordance with the provisions of this paragraph 9, it will be conclusively deemed that such payment or payments have been received by the parties entitled thereto. All charges of the agent or trustee will be borne solely by the parties receiving payments on account of the Royalty Interest.

17. Pubco is not obligated to remain a “foreign issuer” as defined in Rule 902(e) of Regulation S;
