Toronto, November 7, 2014 - Scorpio Mining Corporation ("Scorpio Mining") (TSX: SPM) and U.S. Silver & Gold Inc. ("U.S. Silver & Gold") (TSX: USA) are pleased to announce that they have entered into a definitive agreement (the "Agreement") to complete a merger of equals that will combine their respective businesses (the "Transaction") to create a leading junior silver producer in the Americas.

The combined company will continue under the name of Scorpio Mining Corporation and is positioned to have a strong operating platform with two established producing mines, a third mine in development, an advanced stage exploration project, and pro forma net working capital of approximately C$40 million (including approximately C$21 million in cash) . In addition, the combined company will be led by a highly experienced management team and Board of Directors that will focus on efficiently executing a combined business plan, further reducing costs and optimizing operations given current market conditions and evaluating accretive growth opportunities.

Under the terms of the Transaction, which will be effected by a statutory plan of arrangement, shareholders of U.S. Silver & Gold will receive 1.68 common shares of Scorpio Mining for each share of U.S. Silver & Gold held. Shareholders of Scorpio Mining will not have to exchange their shares of Scorpio Mining in the transaction. Upon completion of the Transaction, the combined company will have approximately 335 million common shares outstanding, of which former shareholders of Scorpio Mining will own approximately 59% and former shareholders of U.S. Silver & Gold will own 41%. The Transaction values the combined company at C$65 million on a basic basis.

Highlights of the Transaction

Key investment highlights of the combined company include:

• Diversified production base: Sustainable annual production of approximately 4.5 - 5.0 million silver equivalent ounces from Scorpio Mining's Cosalá District operations in Sinaloa, Mexico and U.S. Silver & Gold's Galena Complex in Idaho, USA.
• Improving cash cost profile: Cash costs expected to decline as current operations and brownfield development assets are optimized and G&A synergies are realized.
• Proven management team: Extensive experience in all critical mining disciplines with demonstrated capabilities in financing, acquiring, developing and operating open pit and underground mines.
• Solid financial position: Pro forma net working capital of approximately C$40 million (including approximately C$21 million in cash)1 with greater access to capital to fund future growth initiatives.
• Robust reserve and resource base: Supports sustainable operations at current prices with further potential profitable expansion at higher prices from earlier stage internal projects.
• Enhanced market presence: The larger company is expected to appeal to a broader institutional shareholder base, increase analytical following and improve share trading liquidity.
• Compelling value proposition: Leading leverage among junior silver producer equities and attractive relative valuation on net asset value and cash flow multiples.

Management Team and Board of Directors

The combined management team will be led by Darren Blasutti, who will assume the title of President and Chief Executive Officer and will draw from the expertise of both companies. Upon completion of the Transaction, the new Board will be comprised of Mr. Blasutti together with four directors from each of Scorpio Mining and U.S. Silver & Gold. Scorpio Mining founder Peter Hawley will be Chairman of the combined company. Biographies of all proposed directors are included in an attachment to this press release.

"This merger creates a stronger, better positioned company that is capable of not only surviving the current low silver price environment, but potentially transitioning from a junior precious metals company to an intermediate producer over the next couple of years," stated Darren Blasutti, President and Chief Executive Officer of U.S. Silver & Gold. "The diversified low risk asset base, solid financial position, enhanced capital markets profile and proven abilities of the combined management team and Board make this a compelling and unique value proposition for all shareholders."

Ewan Mason, current Chairman of Scorpio Mining, added: "As we look to expand our operating portfolio, we have a strong combined management team that has a very recent track record of significantly reducing operating costs. Management of the combined company will aim to surface tangible near-term cost savings through realization of G&A synergies, focus on cost control, and a systematic review of operations to achieve improved productivity and operational efficiencies at its existing assets. We see this business combination as the first step towards building a leading precious metal producer in the Americas."

Optimized Corporate Structure and Asset Base

The Transaction is supported by strong intrinsic value-creation opportunities that if realized, would provide mutual benefits to the shareholders of both Scorpio Mining and U.S. Silver & Gold.
Single asset mining companies are not efficient in the current market environment and the proposed merger represents an effort to create a stronger combined entity that has the ability to:

• Eliminate duplicate corporate and mine site G&A costs: Management believes that this could save the combined company approximately C$2.0 - C$3.0 million per annum.
• Optimize current operations and development opportunities: In the last two years, the U.S. Silver & Gold team reduced all-in sustaining cash costs by almost 50% at its Galena Complex by implementing strict cost controls and productivity enhancements. Based on detailed mutual due diligence, U.S. Silver & Gold and Scorpio Mining believe there is an opportunity to further improve profitability across the combined asset base through operational improvements, some of which are already being implemented, that could result in an additional C$2.0 -- C$3.0 million of cost savings per annum.
• Allocate capital efficiently: Management plans to allocate existing financial resources over a larger universe of opportunities, not only internally, but to potentially take advantage of opportunities arising from historically low valuations in the precious metals sector.

U.S. Silver & Gold management has intensively reviewed Scorpio Mining's El Cajón asset as part of its due diligence process, including the potential boundary movement and related impact to mineral resources. While the final location of the concession boundary remains subject to confirmation, based on its review of the current facts, U.S Silver & Gold has assumed a potential reduction of total resources at El Cajón of 40% to 50% for purposes of evaluating the Transaction. Despite this, U.S. Silver & Gold believes that pending production from the continued development of El Cajón will contribute positive cash flows for three to four years at current silver prices and will efficiently bridge the development of the 120 Zone at San Rafael in the next two years through shared El Cajón infrastructure. This operating scenario was used by US Silver & Gold as a basis for the relative valuation discussion and exchange ratio determination between the two companies.

Board of Directors' Recommendations

The Board of Directors of each company has determined that the proposed Transaction is in the best interests of their respective shareholders based on a number of factors, including the recommendation of Scorpio Mining's Special Committee and fairness opinions received from their respective financial advisors. Each company's Board of Directors unanimously approved the terms of the Transaction and recommends that their respective shareholders vote in favor of the Transaction. GMP Securities L.P. and Morrison Park Advisors Inc. provided fairness opinions to the Board of Directors of U.S. Silver & Gold and Scorpio Mining, respectively.

Each of the officers and directors of Scorpio Mining and U.S. Silver & Gold has consented to enter into an agreement supporting the Transaction pursuant to which they will vote any common shares of the companies that are held by them in favor of the approval of the Transaction. In addition, Tocqueville Asset Management L.P., which holds or controls approximately 15.9% of the outstanding Scorpio Mining common shares, and Sprott Asset Management LP, which together with Eric Sprott, holds or controls approximately 19.6% of the outstanding U.S. Silver & Gold common shares and approximately 1.6% of the outstanding Scorpio Mining common shares, have entered into lock-up agreements and have agreed to vote in favor of the Transaction.

Details of the Transaction

The Transaction will be carried out by way of court-approved plan of arrangement under the Business Corporations Act (Ontario). It requires the approval of at least 66⅔% of the votes cast by shareholders of U.S. Silver & Gold represented in person or by proxy at a special meeting of the shareholders of U.S. Silver & Gold to be called to consider the plan of arrangement. Approval by a simple majority of votes cast by Scorpio Mining shareholders will also be required at a special meeting of the shareholders of Scorpio Mining that will be held in connection with the Transaction. In addition, the Transaction will be subject to the approval of the Toronto Stock Exchange.

The Agreement includes customary provisions including, among other things, reciprocal non-solicitation covenants, fiduciary outs and rights to match any superior proposal. In the event that a party wishes to terminate the Agreement in order to support an alternative proposal, such party is obligated to pay to the other party an amount equal to 4% of its equity value as a termination payment. Expense reimbursement of C$1 million is payable by a party in the event that approval from its shareholders is not obtained.

Timing

Scorpio Mining and U.S. Silver & Gold expect to mail shareholder information circulars in mid-November 2014 and plan to hold their respective shareholder meetings in mid-December 2014. The Transaction is expected to close prior to year end.
