(MUX)(MUX.TO) is pleased to announce Third Quarter production results and the discovery of a new vein system at the San José mine (49%) in Argentina. The San José mine had another solid quarter of production and El Gallo Phase I (100%) in Mexico achieved its first gold pour. Third Quarter production totaled 10,572 ounces gold and 760,670 ounces silver, representing 25,200 gold and gold equivalent ounces1. The Company remains on track to produce approximately 105,000 gold and gold equivalent ounces in 2012.

San José Mine - Argentina (49%)
The San José mine continued to meet its full year production guidance. Production attributable to McEwen Mining during the Third Quarter totaled 10,274 ounces gold and 760,480 ounces silver, representing 24,899 gold and gold equivalent ounces. The average grade mined at San José during the quarter was 5.24 gpt gold and 402 gpt silver, slightly lower than previous quarters, but in line with the Company''s expectations. The decrease in grade was offset by higher throughput at the process plant. Ounces sold in the quarter were higher than normal due to the sale of accumulated concentrate inventory from the previous quarter.

Discovery of New Vein System at the San José Mine in Argentina
The Company is pleased to announce the discovery of a new vein system at the San José mine. This result is part of the largest exploration program ever being conducted at the mine this year. The new discovery is the high-grade gold/silver Emilia vein, located within the known San José area. The Emilia vein has been traced over a strike length of more than 1,000 meters and it is open to the east and at depth. The Emilia drilling also identified sub-parallel veins called the Estela and Esperanza veins, and the system represents the eastward extension of the east-west Micaela system. For a full set of results please see Table 2. The discovery of this new vein system is encouraging and illustrates the prospective nature of the San José mine and the surrounding land package.
The location of the Emilia vein is shown in Figure 1. Highlights from the holes recently drilled on the Emilia vein include:

Reliability of Information
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. This press release is based entirely on information provided to McEwen Mining by Minera Santa Cruz S.A. (MSC). 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. As the Company is not the operator of the San José mine, there can be no assurance that production information reported to the Company by MSC is accurate, the Company has not independently verified such information and readers are therefore cautioned regarding the extent to which they should rely upon such information.
The technical contents of this news release has been reviewed and approved by Jim Duff, Senior Operations Advisor to the Company, a Qualified Person as defined by Canadian Securities Administrator National Instrument 43-101 "Standards of Disclosure for Mineral Projects". Assay results were reported to McEwen Mining by MSC, which is the operating company for the San José mine joint venture. Assay results for the drilling were reviewed by Jim Duff. All samples were collected in accordance with industry standards. Drill core samples were submitted to Alex Stewart Assayers, Argentina S.A. in Mendoza, Argentina, for fire assay and ICP analysis. Accuracy of results is tested through the systematic inclusion of standards, blanks and check assays. Jim Duff has reviewed the assay certificates from the lab and the quality control measures.
Cautionary Note to U.S. Investors
McEwen Mining reports 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. According to NI 43-101 criteria, the estimation of measured resources and indicated resources involve greater uncertainty as to their economic feasibility than the estimation of proven and probable reserves. Under SEC Industry Guide 7 criteria, measured, indicated and inferred resources are considered Mineralized Material. The SEC considers that in addition to greater uncertainty as to the economic feasibility of Mineralized Material compared to proven and probable reserves, there is also greater uncertainty as to the existence of Mineralized Material. U.S. investors are cautioned not to assume that measured or indicated resources will 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.
