Item 1.01. Entry Into A Material Definitive Agreement

On July 13, 2007 Black Hawk signed a formal option agreement with Perry English (English) for Rubicon Minerals Corp. pursuant to which Black Hawk may earn up to a 100% interest in English's Sand Lake North project located in Ontario, Canada. Under the terms of the agreement, Black Hawk can earn a 100% interest by paying English $41,000 cash (completed) and issuing 25,000 shares on signing (completed) and paying an additional $85,000 cash and issuing 75,000 shares and incurring $700,000 in exploration expenditures over the next two years. English will retain a 2% net smelter royalty ("NSR") of which 1% can be purchased by Black Hawk for $1,000,000 at any time.

Item 3.02. Unregistered Sale of Equity Securities

On July 13, 2007 we issued 25,000 common shares to English to earn a 100% interest in the Sand Lake North project under the option agreement described above.

We issued the securities to one non-U.S. person (as that term is defined in Regulation S of the Securities Act of 1933) in an offshore transaction relying on Regulation S and/or Section 4(2) of the Securities Act of 1933, as amended.

TRANSFERS

10. (a) Subject to subparagraph (c), any party (the "transferring party") may at any time either during the Option Period or thereafter, sell, transfer or otherwise dispose of all or any portion of its interest in and to the Property and this Agreement provided that any purchaser, grantee or transferee of any such interest shall have first delivered to the other party (in this section the "other party") its agreement related to this Agreement and to the Property, containing:

(i) a covenant by such transferee to perform all the obligations of the transferring party to be performed under this Agreement in respect of the interest to be acquired by it from the transferring party to the same extent as if this Agreement had been originally executed by such transferee; and

(ii) a provision subjecting any further sale, transfer or other disposition of such interest in the Property and this Agreement or any portion thereof to the restrictions contained in this paragraph (a).

Page 9

　

(b) No assignment by the transferring party of any interest less than its entire interest in this Agreement and in the Property shall, as between the transferring party and the other party, discharge it from any of its obligations hereunder, but upon the transfer by the transferring party of the entire interest at the time held by it in this Agreement, whether to one or more transferees and whether in one or in a number of successive transfers, the transferring party shall be deemed to be discharged from all obligations hereunder save and except for the payment of the Royalty or other fulfillment of contractual commitments accrued due prior to the date on which the transferring party shall have no further interest in this Agreement.

(c) If any party (the "transferring party") should receive a bona fide offer from an independent third party (the "Proposed Purchaser") dealing at arm's length with the transferring party to purchase, by way of option or otherwise, all or a part of its interest in the Property, which offer the transferring party desires to accept, or if the transferring party intends to sell, by way of option or otherwise, all or a part of its interest in the Property other than to an affiliated company:

(i) The transferring party 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 transferring party, as the case may be.

(ii) The Offer shall specify the price, terms and conditions of such sale, the name of the Proposed Purchaser and shall, in the case of an intended offer by the transferring party, disclose the person or persons to whom the transferring party intends to offer its interest and, if the offer received by the transferring party from the Proposed Purchaser provides for any consideration payable to the transferring party otherwise than in cash, the Offer shall include the transferring party's good faith estimate of the cash equivalent of the non-cash consideration.

Page 10

　

(iii) If within a period of 60 days of the receipt of the Offer the other party notifies the transferring party in writing that it will accept the Offer, the transferring party shall be bound to sell such interest to the other party on the terms and conditions of the Offer. If the Offer so accepted by the other party contains the transferring party's good faith estimate of the cash equivalent of the non cash consideration as aforesaid, and if the other party disagrees with the transferring party's best estimate, the other party shall so notify the transferring party 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 transferring party, the acceptance by the other party shall be effective and binding upon the transferring party and the other party, and the cash equivalent of any such non-cash consideration shall be deter mined by binding arbitration 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 transferring party, against receipt of an absolute transfer of clear and unencumbered title to the interest of the transferring party being sold, the total purchase price which is specified in its notice to the transferring party and such amount shall be credited to the amount determined following arbitration of the cash equivalent of any non cash consideration.

(iv) If the other party fails to notify the transferring party before the expiration of the time limited therefore that it will purchase the interest offered, the transferring party 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, but the terms of this paragraph shall again apply to such interest if the sale to the Proposed Purchaser is not completed within such 60 days.

(v) Any sale hereunder shall be conditional upon the purchaser delivering a written undertaking to the other party, in form and substance satisfactory to its counsel, to be bound by the terms and conditions of this Agreement, including this paragraph (c).

Page 11

　

(d) Paragraph (c)(v) hereof shall apply, mutatis mutandis, to any sale, by way of option or otherwise, of all or part of the transferring party's interest in the Property to an affiliated company.

SURRENDER OF PROPERTY INTERESTS PRIOR TO TERMINATION OF AGREEMENT

11. The Optionee may at any time during the Option Period elect to abandon any one or more of the mineral claims comprised in the Property by giving notice to the Optionor of such intention. Any claims so abandoned shall be kept in good standing under the laws of the jurisdiction in which they are situate for at least 12 months from the date of abandonment. Upon any such abandonment, the mineral claims so abandoned shall for all purposes of this Agreement cease to form part of the Property and, if title to such claims has been transferred to the Optionee the Optionee shall retransfer such title to the Optionor at the Optionee's expense.

FORCE MAJEURE

12.

(b) The Optionee shall give prompt notice to the Optionor of each event of force majeure and upon cessation of such event shall furnish to the Optionor with notice to that effect together with particulars of the number of days by which the obligations of the Optionee hereunder have been extended by virtue of such event of force majeure and all preceding events of force majeure.

Page 13

appointed, the single arbitrator, shall fix a time and place in Toronto, Ontario for the purpose of hearing the evidence and representations of the parties, and he shall preside over the arbitration and determine all questions of procedure not provided for under such Act or this section. After hearing any evidence and representations that the parties may submit, the single arbitrator, or the arbitrators, as the case may be, shall make an award and reduce the same to writing, and deliver one copy thereof to each of the parties. The expense of the arbitration shall be paid as specified in the award.

(d) The parties agree that the award of a majority of the arbitrators, or in the case of a single arbitrator, of such arbitrator, shall be final and binding upon each of them.

DEFAULT

15. If at any time during the Option Period the Optionee is in default of any material provision in this Agreement other than the provisions of subparagraph 4(b) for which no notice of default need be given, the Optionor may terminate this Agreement, but only if:

(b) the Optionee has not, within 30 days following delivery of such notice of default, cured such default or commenced proceedings to cure such default by appropriate payment or performance, the Optionee hereby agreeing that should it so commence to cure any default it will prosecute the same to completion without undue delay.
