TORONTO, ONTARIO–(Marketwired – March 9, 2015) – McEwen Mining Inc. (NYSE:MUX)(TSX:MUX) reports its operating and financial results for Q4 and full-year 2014.

The Company had record production in the fourth quarter and full-year 2014, beating both production and cost guidance. The strong operational performance in the fourth quarter is projected to continue throughout 2015.

The table below provides Q4 and full-year production and cost per ounce results for 2014 and 2013 along with projections of such for 2015.

2014 Results & 2015 Guidance

See notes below.

2015 Guidance

For 2015, we forecast production of 96,500 gold oz. and 3.12 million silver oz. At a silver-to-gold ratio of 75:1, this equates to 138,100 gold equivalent oz. at all-in sustaining costs (Including corporate general and administrative costs) of $1,125 per gold equivalent oz.

At El Gallo 1, we expect to produce 50,200 gold equivalent oz. at all-in sustaining costs of $750per gold equivalent oz. This significant improvement compared to 2014 is due to a much higher grade of 2.6 gpt Au, reduced crusher throughput and lower mining, blasting and cyanide costs.

At San Jose, the Company's 49% share of production is forecast to be 46,500 gold oz. and 3.1 million silver oz. At a silver-to-gold ratio of 75:1, this equates to 87,800 gold equivalent oz. at all-in sustaining costs of $1,225 per gold equivalent oz. This is similar to 2014 results calculated at a silver-to-gold ratio of 60:1.

Development Pipeline

We will deliver updated feasibility studies for both El Gallo 2 and Gold Bar in the third quarter of 2015.

The El Gallo 2 project is fully permitted and ready to build. The updated feasibility study will examine the potential for utilizing used equipment and a different processing technique that increases recoveries while reducing retention times, consumables and the number of tanks. We are targeting capital expenditures of $130 million, down from the $180 million in the 2012 feasibility study.

For Gold Bar, the 2011 prefeasibility study outlined an open pit, heap leach operation utilizing two-stage crushing for average annual production of approximately 51,000 ounces of gold over an 8-year mine life at an estimated initial capital expenditure of $56 million. The 2015 feasibility will examine the potential for utilizing used equipment and run-of-mine ore processing.

Financials

Liquidity

At March 6, 2015 the Company had $22 million in cash and precious metals and no bank debt. The cash on hand and projected to be generated in 2015 is sufficient to fund our exploration, operations and G&A expenses.

2014 Annual Results

We performed a strategic review of our property holdings taking into account the current metal prices, the carrying values, our future exploration and development plans and our treasury and decided to focus on our most prospective assets. As a result, we decided to significantly reduce the carrying value of our properties. 
Although these impairments represent large accounting losses, they do not impact the cash flow of the Company.

We reported a consolidated net loss of $312 million, or $1.05 per share, in 2014 compared to$148 million, or $0.50 per share in 2013. The net loss for 2014 includes impairment charges of$228 million for Los Azules, $98 million for our Nevada properties, $27 million for our exploration properties in Santa Cruz, and $21 million on our investment in the San Jose mine.

The $228 million impairment charge on Los Azules ($120 million in Q2 2014 and $108 million in Q4 2014) is the result of a decline in the observed market value of comparable copper transactions. The impairments to the Nevada and Argentina exploration properties both occurred in Q4 2014 and are due to declines in observed market transactions and a decision by the Company to rationalize our non-core property holdings. The impairment to our investment in the San José mine is due to decreases in long term silver price assumptions and the value of the exploration properties surrounding the mine.

The adjusted net loss for 2014 was $33 million, or $0.11 per share. This compares to a net loss of$31 million, or $0.10 per share, for 2013. Adjusted net loss removes the impact of impairment charges, foreign currency gains or losses, and non-recurring items.

The foregoing news release and technical report are available under the Corporation's profile on SEDAR (www.sedar.com).

There are significant risks and uncertainty associated with commencing production or changing production plans without a feasibility, pre-feasibility or scoping study. The expansion to El Gallo 1 has not and may not be explored, developed or analyzed in sufficient detail to complete an independent feasibility or pre-feasibility study. Further, although the subject of a 2012 feasibility study, the Company does not have a current feasibility study on the El Gallo 2 project. As such, each of the foregoing may ultimately be determined to lack one or more geological, engineering, legal, operating, economic, social, environmental, and other relevant factors reasonably required to serve as the basis for a final decision to complete the expansion or construction of all or part of these projects.

RELIABILITY OF INFORMATION REGARDING THE SAN JOSÉ MINE

Minera Santa Cruz S.A., the owner of the San José mine, is responsible for and has supplied to the Company all reported results from the San José mine. McEwen Mining's joint venture partner, a subsidiary of Hochschild Mining plc, and its affiliates other than MSC do not accept responsibility for the use of project data or the adequacy or accuracy of this release.

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.

(1) Total Cash Costs and All-in Sustaining

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 Annual Report on Form 10-K for the fiscal year ended December 31, 2014.

(2) Adjusted net income (loss)

Adjusted net income (loss) excludes the following items from net income (loss): impairment charges, net of tax; foreign currency gains and losses, including the impact of the devaluation Argentine peso relative to the U.S. dollar; other non-recurring items, if applicable. We use and report this measure because we believe it provides investors and analysts with a useful measure of the underlying operating performance of our core mining business. A reconciliation to the nearest U.S. GAAP measure is provided in McEwen Mining's Annual Report on Form 10-K for the fiscal year ended December 31, 2014.

CAUTIONARY NOTE TO US INVESTORS REGARDING RESOURCE ESTIMATION

McEwen Mining prepares its resource estimates in accordance with standards of the Canadian Institute of Mining, Metallurgy and Petroleum referred to in Canadian National Instrument 43-101 (NI 43-101). These standards are different from the standards generally permitted in reports filed with the SEC. Under NI 43-101, McEwen Mining reports measured, indicated and inferred resources, measurements, which are generally not permitted in filings made with the SEC. The estimation of measured resources and indicated resources involve greater uncertainty as to their existence and economic feasibility than the estimation of proven and probable reserves. U.S. investors are cautioned not to assume that any part of measured or indicated resources will ever be converted into economically mineable reserves. The estimation of inferred resources involves far greater uncertainty as to their existence and economic viability than the estimation of other categories of resources.
