Item 1.01 Entry into a Material Definitive Agreement

On July 3, 2012, Shoshone Silver/Gold Mining Company (“Shoshone”) executed an Option to Lease agreement (“the Agreement”) with Black Mountain Resources Limited (“BMZ”), an Australian company listed on the Australian Securities Exchange. Under the Agreement, Shoshone grants BMZ an option (“the Option”) to lease for a 15-year period Shoshone’s Lakeview District Mill (“the Mill”). The Agreement also gives BMZ the right to acquire Shoshone’s mineral claims comprising the Weber Mine Property in the Lakeview District upon BMZ’s executing the Option.

Within seven days of executing the Agreement, Shoshone will receive a nonrefundable cash payment of $500,000 from BMZ. In turn, upon executing the Agreement, BMZ is given the right to conduct due diligence for a period of 90 days. If BMZ chooses to execute the Option within this period, it will issue a total of 5,000,000 shares of its common stock to Shoshone, with 2,500,000 of such shares to be issued after a one year voluntary escrow. Upon execution of the Option, BMZ will become the owner of the Weber Mine Property claims.

Under the Agreement, Shoshone also grants to BMZ a preemptive right and right of first refusal to acquire Shoshone’s interests in its mining claims located in the Lakeview Mining District and the Coeur d’Alene Mining District of Idaho.

By executing the Option, BMZ will be responsible for all maintenance on and capital improvements to the Mill and will be responsible for paying a net $10 per ton toll milling charge to Shoshone for each ton of ore processed. For every year after the first ten years of the Lease, BMZ agrees to make minimum toll payments to Shoshone of $250,000 per year. Upon termination of the Lease, any capital improvements to the Mill become the property of Shoshone.

Under the Agreement, Shoshone may use the Mill to process its own ore by making commercial payments to BMZ. The Lease may be extended beyond its primary term for two successive 15-year periods.
