McEwen Mining 2013 Production Up 33% Over 2012; 139,455 Gold Eq. oz Produced in 2013

TORONTO, ONTARIO--(Marketwired - Jan 14, 2014) - McEwen Mining Inc. (NYSE:MUX)(TSX:MUX) is pleased to announce full-year and Q4 production results. For the full-year, the Company's total production was 139,455 gold eq. oz comprised of 79,158 gold oz and 3,135,467 silver oz. This represents an approximate 33% increase compared to 2012.

In Q4 the Company produced 37,167 gold eq. oz (20,686 gold oz and 857,011 silver oz). This is 15% higher than Q4 2012.

Production for 2014 is forecast to be roughly in line with 2013, between 135,000-140,000 gold eq. oz (approximately 81,000 gold oz and 3,225,000 silver oz). The Company expects production during the second half of 2014 to exceed the first half due to the expansion at El Gallo 1 scheduled for completion at the end of Q1 and ramping up in Q2. Production costs in 2014 are forecasted to be similar to 2013, with cash costs between $750-$850 per gold eq. oz and all-in sustaining costs between $1,100-$1,200 per gold eq. oz. The Company projects to produce 170,000 gold eq oz in 2015, excluding any potential production from El Gallo 2. The decision as to whether to proceed with El Gallo 2 is still pending and subject to a number of factors, including obtaining the required financing. Final production costs for 2013 will be reported in early March 2014 with year-end financials.

"In addition to executing on our organic growth plans, we continue to analyze M&A opportunities. Our ideal candidate would significantly increase our production, lower our cost profile, and have cash and free cash flow to facilitate the construction of El Gallo 2. Our geographic focus remains on the Americas.

As the Company's largest shareholder, I can say management is focused on growth that produces a higher share value and price. It is not growth just to be a larger company. The fact that I do not take a salary means that the only way I will make money is the same as all the shareholders do and that is through a higher share price," stated Rob McEwen, Chairman and Chief Owner.

2. El Gallo 1 Mine, Mexico (100%)

El Gallo 1 had a successful first full-year of commercial production, producing 31,129 gold eq. oz (30,733 gold oz and 20,635 silver oz). During Q4, El Gallo 1 produced 7,760 gold eq. oz (7,687 gold oz and 3,786 silver oz). In 2014, El Gallo 1 is forecasted to produce 37,500 gold equivalent ounces (37,000 gold oz and 25,000 silver oz).

El Gallo 1 is currently being expanded from 3,000 to 4,500 tonnes per day. The expansion is scheduled to be completed by the end of Q1 2014. The increased capacity, combined with higher grades as mining moves deeper in the pit, is expected to increase production to 75,000 gold equivalent ounces by 2015.

3. Future Mines

El Gallo 2, Mexico (100%)

The Environmental Impact Statement (EIS) permit for El Gallo 2 was approved by the federal Mexican Secretariat of Environment and Natural Resources (SEMARNAT) on November 8, 2013. The final Change of Land Use permit is being reviewed by the state government and a decision on this permit is expected during Q1 2014. This final permit would allow construction and operations to commence at El Gallo 2 under a mill scenario. The Company has not yet made a decision as to whether to proceed with El Gallo 2. This decision, will among other things, be determined by the timing of permits, the availability of capital and precious metals prices.

Gold Bar, Nevada (100%)

McEwen Mining continues to advance the Gold Bar permitting process for construction and production. Gold Bar is forecasted to produce 50,000 ounces gold per year for 8 years at a cash cost of approximately $700 per ounce. The project is located primarily on public lands managed by the Bureau of Land Management (BLM). The BLM and the Nevada Division of Environmental Protection (NDEP) are the primary government agencies responsible for approving the permits that would allow the Company to begin construction. The Company expects to have the permits required for Gold Bar by Q1 2015.

There are significant risks and uncertainty associated with construction, commencing production or changing production plans without a current feasibility, pre-feasibility or scoping study. 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, El Gallo 2 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 of all or part of this project.

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 TO US INVESTORS

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.

CAUTIONARY NOTE REGARDING NON-GAAP MEASURES

In this news release, we have provided 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, royalty costs, refining and treatment charges, sales costs 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 sustaining capital expenditures. 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 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.
