TORONTO, ONTARIO--(Marketwired - April 16, 2015) - McEwen Mining Inc. (NYSE:MUX)(TSX:MUX) reports gold production increased 23% and silver production decreased 10% in Q1 2015 vs Q1 2014. Gold and silver recoveries were artificially low as a result of the recent gold theft and will return to normal in Q2. Production costs for Q1 2015 will be reported with the quarterly financial results in early May 2015.

Guidance for 2015 production remains unchanged at 96,500 gold ounces and 3.1 million silver ounces.

Individual Mine Performance

El Gallo 1, Mexico

Gold production in Q1 2015 was 15,243 gold ounces, which was 17% higher than guidance due to a higher gold grade and recovery. The average gold grade crushed was 3.17 gpt.

Gold recoveries are calculated from the ratio of total ounces produced to contained ounces stacked and were low in Q1 2015 as there was only one gold pour in March. If in the first quarter we had poured the 7,000 ounces that were stolen, the recovery rate would have been 68%.

Production in Q2 2015 is expected to be 14,000 ounces of gold and for the year remains at 50,000 ounces. Management is reviewing guidance of all-in sustaining costs of $750 per gold ounce due to the yet unknown final insurance proceeds from the stolen gold and planned security upgrades.

San José, Argentina (49%)

Our attributable production from San José in Q1 2015 was 9,453 gold ounces and 644,255 silver ounces.

Compared to Q1 2014, gold and silver ounces produced were down 12% and 11% respectively. This is primarily the result of a 19% decrease in tonnes treated due to a planned shutdown of the processing plant for mandatory vacation in the quarter.

Full year guidance for San José remains at 46,500 gold ounces and 3.1 million silver ounces net to McEwen Mining at all-in sustaining costs of $1,225 per gold equivalent ounces.

Cautionary Note Regarding Non-GAAP Measures

In this report, we have provided information prepared or calculated according to U.S. GAAP, as well as provided some non-U.S. GAAP ("non-GAAP") performance measures. Because the non-GAAP performance measures do not have any standardized meaning prescribed by U.S. GAAP, they may not be comparable to similar measures presented by other companies.

Total cash costs consist of mining, processing, on-site general and administrative costs, community and permitting costs related to current explorations, royalty costs, refining and treatment charges (for both doré and concentrate products), sales costs, export taxes and operational stripping costs. All-in sustaining cash costs consist of total cash costs (as described above), plus environmental rehabilitation costs, mine site exploration and development costs, and sustaining capital expenditures. In order to arrive at our consolidated all-in sustaining costs, we also include corporate general and administrative expenses. Depreciation is excluded from both total cash costs and all-in sustaining cash costs. Total cash cost and all-in sustaining cash cost per ounce sold are calculated on a co-product basis by dividing the respective proportionate share of the total cash costs and all-in sustaining cash costs for the period attributable to each metal by the ounces of each respective metal sold. We use and report these measures to provide additional information regarding operational efficiencies both on a consolidated and an individual mine basis, and believe these measures provide investors and analysts with useful information about our underlying costs of operations. A reconciliation to the nearest U.S. GAAP measure is provided in McEwen Mining's Quarterly Report on Form 10-k for the year ended December 31, 2014.
