On September 10, 2012, McEwen Mining Inc. (the “Company”) issued a press release regarding results of a feasibility study for Phase II of its El Gallo project, in Sinaloa state, Mexico.  A copy of the press release is attached to this report as Exhibit 99.1.

The information furnished under this Item 7.01, including the exhibits, shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, except as shall be expressly set forth by reference to such filing.

Cautionary Statement

With the exception of historical matters, the matters discussed in the press release include forward-looking statements within the meaning of applicable securities laws that involve risks and uncertainties that could cause actual results to differ materially from projections or estimates contained therein. Such forward-looking statements include, among others, statements regarding current and future exploration and development activities, estimated production schedules and the Company’s future cash flows. Factors that could cause actual results to differ materially from projections or estimates include, among others, metals prices, economic and market conditions, start-up of milling operations and future drilling results, as well as other factors described in our Annual Report on Form 10-K for the year ended December 31, 2011, and other filings with the United States Securities and Exchange Commission (“SEC”). Most of these factors are beyond the Company’s ability to predict or control. The Company disclaims any obligation to update any forward-looking statement made in the press release, whether as a result of new information, future events, or otherwise. Readers are cautioned not to put undue reliance on forward-looking statements.

The press release furnished with this report provides a summary of certain reserve estimates of the Company.  The reports that contain such estimates were prepared in accordance with Canadian National Instrument 43-101 (“NI 43-101”).  As a company listed on the Toronto Stock Exchange, the Company is required to comply with NI 43-101, which requires the preparation of a technical report and includes estimates of potential mineral resources and reserves for further targeted exploration disclosed pursuant to the applicable provisions of NI 43-101.  However, reporting requirements in the United States for disclosure of mineral properties are governed by the SEC and included in the SEC’s Securities Act Industry Guide 7 entitled “Description of Property by Issuers Engaged or to be Engaged in Significant Mining Operations” (“Guide 7”).  NI 43-101 and Guide 7 standards are substantially different.  For example, the SEC only permits the disclosure of proven or probable reserves, which in turn, requires the preparation of a “final” or “bankable” feasibility study demonstrating the economic feasibility of mining and processing the mineralization.  The feasibility study for Phase II of El Gallo was not prepared in accordance with Guide 7 and the reserves discussed in the study may not qualify as “reserves” as defined by Guide 7.  The Company cannot be certain that any part of the mineralized material at any of its properties will ever be confirmed or converted into Guide 7 compliant “reserves.”  U.S. investors are cautioned not to assume that all or any part of the mineralized material will ever be confirmed or converted into reserves or that a potential mineral resource can be economically or legally extracted.
