TORONTO, ONTARIO - (July 17, 2014) - McEwen Mining Inc. (NYSE: MUX) (TSX: MUX) is pleased to announce production results for Q2 2014. Production in Q2 was 31,200 gold eq. oz(1)(2) comprised of 18,863 gold oz and 740,276 silver oz, consistent with guidance. This is a decrease of 8% compared to Q2 2013 and 3% compared to Q1 2014. Full-year guidance remains unchanged at 135,000-140,000 gold eq. oz as production is expected to increase in Q4, due to 1) 50% more processing capacity at El Gallo 1; and 2) higher grades at San José. Production costs will be reported in August 2014 with Q2 financials.

San José Mine, Argentina (49%)

McEwen Mining’s attributable production from the San José mine during Q2 2014 was 23,033 gold eq. oz (10,750 gold oz and 737,001 silver oz). This is 9% lower than the comparable period in 2013 and 1% higher than Q1 2014. Production was lower year-over-year due to lower gold and silver grades. Production was up slightly quarter-over-quarter due to more tonnes milled and processed. McEwen Mining’s share of production from San José in 2014 is forecasted to be 97,500 gold eq. oz (44,000 gold oz and 3,200,000 silver oz), with approximately 51,500 gold eq. being produced in the second half of the year.

El Gallo 1 Mine, Mexico (100%)

In Q2 2014 the El Gallo 1 mine produced 8,167 gold eq. oz (8,113 gold oz and 3,275 silver oz). This is 4% lower than the comparable period in 2013 and 13% lower than Q1 2014. Production was lower due to lower gold grades and temporary downtime at the process plant that was associated with commissioning of the expansion. The expansion, which will increase the processing capacity from 3,000 to 4,500 tonnes per day, was completed mid-May and commissioning is underway. The mine is expected to be operating at its full capacity by the start of Q4. In 2014, El Gallo 1 is forecasted to produce 37,500 gold equivalent ounces (37,000 gold oz and 25,000 silver oz), with approximately 20,000 gold eq. being produced in the second half of the year.

Expected Los Azules Impairment Charge

We are conducting an impairment test of our Los Azules project in Argentina as a result of the recently announced acquisition of Lumina Copper Corp. by First Quantum Minerals Ltd., for approximately C$470 million. Lumina’s only significant asset is the Taca Taca copper project located in Salta, Argentina.  While there are some notable differences between Taca Taca and Los Azules, we believe the similarities in project scale and location within Argentina warrant consideration for the Lumina transaction to be a triggering event for impairment analysis.  Our preliminary analysis, which places a substantial weighting on the announcement day value of the Lumina transaction to value Los Azules, indicates a pre-tax asset impairment charge in the range of approximately $90-135 million(1). The actual amount, when we have completed the final impairment

2

assessment, will be reported in our quarterly 10-Q which is due to be filed on August 7, 2014.

“With First Quantum acquiring Lumina Copper and their Taca Taca project, Los Azules moves to the forefront in terms of world-class, undeveloped, high-grade copper assets not owned by a major mining company. As we have said in the past, Taca Taca serves as a good proxy for the value of Los Azules and we believe this transaction demonstrates value in projects located in Argentina”, said Rob McEwen, Chief Owner, Chairman and CEO.

(1) This is a preliminary estimate range and the impairment testing work, both internally and in collaboration with our external valuation consultants is ongoing, including with respect to various underlying assumptions and comparable transaction analysis.  We note that the Lumina/First Quantum transaction is not scheduled to close until approximately August 30, 2014.  As of March 31, 2014, we carried the Los Azules project at a pre-tax net book value of approximately $431 million.
