TORONTO, ONTARIO–(Marketwired – June 23, 2015) – McEwen Mining Inc. (NYSE:MUX)(TSX:MUX) is pleased to announce that production at the El Gallo Mine has exceeded our guidance for the second quarter. With approximately 15,600 gold equivalent ounces produced so far in Q2, this marks the third consecutive quarter of record production at the El Gallo Mine. Our production in Q1 this year totaled 15,391 gold equivalent ounces with year-to-date production of approximately 31,000 gold equivalent ounces.

The increase in gold production was driven by the combination of higher grades mined in the pit and improved gold recoveries consistent with the first quarter of this year. The Company continues to demonstrate the trend of sequential quarter-over-quarter increased production while continuing to lower our cash costs. These achievements demonstrate the corporations focus on delivering a stable production profile with a consistent cost base while generating free cash flow.

San José Mine

Second quarter production at the San José Mine (49% owned) will be approximately 11,000 ounces of gold, and 788,000 ounces of silver attributable to us. Production is on track to achieve our full year guidance of 46,500 ounces of gold, and 3.1 million ounces of silver. San José experienced an intermittent work stoppage in June that had a limited impact on second quarter production.

Consolidated Production & Guidance

Total production during the second quarter will be approximately 26,530 ounces of gold and 797,000 ounces of silver. Full year production guidance remains unchanged at 96,500 ounces of gold and 3.12 million ounces of silver.

The Company will provide a detailed production and operational update in the upcoming weeks when the quarter is complete.
