McEwen Mining Provides Second 2012 Operational and Development Update

Wednesday, August 08, 2012

McEwen Mining Provides Second 2012 Operational and Development Update17:00 EDT Wednesday, August 08, 2012TORONTO, ONTARIO--(Marketwire - Aug. 8, 2012) -(All Amounts in US Dollars Unless Otherwise Stated)McEwen Mining Inc. (NYSE:MUX)(TSX:MUX) is pleased to provide a summary of the second quarter, including operational and development updates, for its projects in Argentina, Mexico and Nevada. During the six months ending June 30th, the Company's attributable production was 47,640 ounces of gold and gold equivalent and remains on schedule to produce a total of 105,000 ounces in 2012. Production was up 9% over the previous quarter and up 17% over second quarter 2011. Balance SheetAt the end of the second quarter, McEwen Mining had cash and liquid assets of $38 million, comprised of cash of $23.4 million, silver and gold bullion at market value of $14.1 million and marketable securities of $0.5 million. The Company remains debt free.During the quarter no dividends were received from the Company's 49% owned San José mine, due to a delay in sales in Argentina. This delay was the result of additional changes to the export revenue repatriation requirements in Argentina announced in the first half of the year. Full sales resumed towards the end of the second quarter and McEwen Mining received a $2.1 million dividend on July 30, 2012. The proceeds from this dividend will remain in Argentina to help fund exploration at the Los Azules Copper project this fall. We expect to receive further dividends from San José during 2012, although the timing and amount will depend upon precious metals prices, production levels, operating costs, capital expenditures, Argentine central bank and government restrictions, as well as other factors beyond our control.During the second quarter major capital expenditures related to El Gallo Phase 1 included $7 million for construction and $3.5 million in pre-production mining. At the end of the second quarter approximately $2 million remain to be spent on construction, with initial revenues from gold sales expected in early September. Other major expenditures during the second quarter included $10.1 million for exploration at the Company's various projects. Due to the delay in cash flows from Argentina and to ensure Phase 2 development at El Gallo remains on track the Company anticipates completing a financing this fall. The Company and its Board believe it is important to provide guidance to the market with respect to our upcoming capital requirements and further believe a Rights Offering, versus alternative financing methods would be in the best interest of shareholders. The rights to purchase shares of our common stock would be offered to our existing shareholders at a substantial discount to the market value of our common stock. Rob McEwen, Chief Owner, has indicated he is willing to back-stop a rights offering in the aggregate amount of up to $50 million. Prior to launching any financing, the Company will, among other things, need to complete and announce the results of the ongoing El Gallo Phase 2 feasibility study. The Company expects this feasibility study to be completed near the end of September. Any financing (including a Rights Offering back-stopped by Mr. McEwen) remains subject to numerous approvals, including by the independent board of directors. San José Mine, Argentina (49%)Solid Q2 Production - Cash Flow Resumes Final production results for the San José mine during the second quarter was 21,946 ounces gold and 1,500,000 ounces silver, representing 50,792 gold and gold equivalent ounces (converting the silver into gold using a 52:1 exchange ratio) (100% basis). The San José mine remains on target to meet full-year production guidance of 85,000 ounces of gold and 5.7 million ounces of silver or 192,500 ounces of gold and gold equivalent (100% basis). McEwen Mining's attributable interest is 49% of these production totals.Total Cash Costs during the period equaled $842 per ounce gold and $15.32 per ounce silver. Gold equivalent cash costs equaled $816 per ounce (converting the cash cost of producing an ounce of silver into the gold equivalent using a 52:1 exchange ratio). The increase in cash costs versus the first quarter and prior year period is primarily related to higher labor costs that took effect during the quarter and inflationary pressures present within Argentina. Also, cash costs increased due to a higher percentage of sales coming from concentrate versus doré. The sale of concentrate includes higher export taxes and refining/treatment charges. The percentage of production coming from concentrate was higher during the second quarter due to modifications to the process plant. The balance between concentrate and doré production is now back to normal levels.The average grade of ore processed during the second quarter was 5.98 gpt gold and 430 gpt silver. Gold and silver recoveries averaged 88.6% and 84.2%, respectively. During the second quarter 31,900 meters of diamond drilling was completed at the San José mine. This year a total of 110,000 meters or $14 million has been budgeted for exploration at the mine. An exploration update for San José is scheduled for the third quarter.

Total capital expenditures are expected to be slightly below the Company's initial $15 million estimate. Commissioning of the crushers and loading of material onto the heap leach pad began near the end of July and are ramping up towards the design capacity of 3,000 tonnes per day. Commissioning of the process plant has recently begun, with initial production scheduled for late August.During the second quarter, 7,100 meters of diamond drilling was completed at the El Gallo complex. The most impressive expansion hole came from the Phase 1 production area, returning 1.1 gpt gold over 71.3 meters, including 6.6 gpt gold over 4.9 meters (previously released on July 19, 2012), which is believed to be the widest intersection of +1 gpt gold recorded at the property. El Gallo Phase 1 is expected to produce 10,000 ounces of gold during the second half of 2012 and continue at 30,000 ounces of gold per year after ramp-up. Phase 2, which, subject to a positive feasibility study, is expected to be completed in 2014, is forecasted to produce an additional 5 million ounces of silver and 5,500 ounces of gold per year, for combined production of 130,000 ounces of gold and gold equivalent.

Gold Bar is forecasted to produce 50,000 ounces of gold per year. 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. Baseline data collection is ongoing in accordance with the BLM guidelines and is expected to be completed during third quarter, 2013. The Company is planning to submit its mining permit application (Plan of Operation) during the fourth quarter, 2013. 2) Tonkin ProjectThe Tonkin project, which currently contains 1.4 million ounces of gold in the measured and indicated categories (32.3 million tonnes @ 1.39 gpt gold) and 0.3 million ounces of gold in the inferred (8.4 million tonnes @ 1.13 gpt gold), is undergoing a series of metallurgical tests for possible process alternatives that are common to mines in Nevada. The primary process being explored is a flotation concentrate followed by autoclaving. Test work is being completed by McClelland Labs and results are expected late third quarter. With recent decreases in Nevada power costs and higher gold prices, Tonkin could become a potential future source of gold production. However, the Company's current production forecasts do not include any production from Tonkin. Los Azules Copper Project, Argentina (100%)World Class Copper Asset - Size + Grade Preparations are well underway for the upcoming Los Azules drill season, which is expected to commence in November. Los Azules is one of the world's largest and highest grade undeveloped copper porphyry's. McEwen Mining has signed a contract with Major Drilling to provide four core and one reverse circulation drills. The drills are considerably more powerful than the ones used during past field seasons. The Company believes this will increase the likelihood of reaching target depths (+700 meters), where additional high-grade copper mineralization has been discovered. McEwen Mining anticipates starting the upcoming drill season in November, adding 2 months to the program and permitting a helicopter pad that may allow the drills to operate 12 months a year. A portion of the Los Azules Copper project is subject to litigation in the Courts of British Columbia. Shareholders and other interested parties are encouraged to review our most recent quarterly filings for detailed information. The trial is set to commence in November 2012 and last for approximately six weeks. Santa Cruz Exploration, Argentina (100%)During the second quarter, a total of 8,200 meters of percussion drilling was completed on McEwen Mining's Celestina project near Anglo Ashanti's Cerro Vanguardia mine (Annual production: 230,000 gold ounces - 0.9 million silver ounces). Exploration work ceased towards the end of May with the onset of Argentinian winter. The Company is evaluating the results of this exploration work to see if further drilling is justified at this project.The drill permits for McEwen Mining's 100% owned claim package adjacent to the San José mine and Goldcorp's Cerro Negro project are in review with the provincial government. The Company has been notified that they should receive the approval of these permits by the end of the third quarter, 2012. The Company is planning to establish a diamond core drilling program to commence with the receipt of these permits.Second Quarter Conference Call Details McEwen Mining will be hosting a conference call to discuss second quarter results and project developments on August 9, 2012 at 10:00 am EST.WEBCAST: http://www.gowebcasting.com/3691 TELEPHONE:Participant dial-in number(s): 1-719-325-2463 / 1-888-523-1228Participant pass code: 4321607REPLAY:Dial-in number(s): 1-888-203-1112 / 1-719-457-0820Pass code: 4321607This news release has been reviewed and approved by William Faust, P.E, McEwen Mining's Chief Operating Officer, who is a Qualified Person as defined by National Instrument 43-101.ABOUT MCEWEN MINING ( www.mcewenmining.com ) The goal of McEwen Mining is to qualify for inclusion in the S&P 500 by 2015 by creating a high growth, low-cost, mid-tier silver and gold producer focused in the Americas.

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.CAUTIONARY NON-GAAP MEASURESIn 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 cost per ounce are calculated on a co-product basis and by dividing the respective proportionate share of the total cash costs for the period attributable to each metal by the ounces of each respective metal produced. Total cash cost per ounce is the sum of the geology, mining, processing, general and administration costs, royalties, refining and treatment charges (for both doré and concentrate products), sales costs and export taxes divided by the number of ounces of gold and silver produced at the mine. Depreciation is excluded from total cash costs.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).

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.CAUTION CONCERNING FORWARD-LOOKING STATEMENTSThis press release contains certain forward-looking statements and information, including "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995.
