 "Action with McEwen Mining was quite interesting this week and, particularly, on Friday. Stock has refused to follow the Gold that day and stubbornly was climbing higher all day. Rob McEwen was making some of his magic on Thursday at the conference call after the Q1 update and McEwen Mining Shareholders meeting will be taken place next week. Chief Owner has promised release from one of the exploration program before it and Los Azules new resource estimate is due by the end of May.

TORONTO, ONTARIO--(Marketwired - May 14, 2013) - McEwen Mining Inc. (NYSE:MUX)(TSX:MUX) announces that follow-up core holes at the new Central Zone have expanded the gold mineralization in several directions. Central is located inside the Company's El Gallo 1 mine inSinaloa, Mexico (Fig. 1). It is situated between two known resources, where mining began onApril 1st (Fig. 2). Based on the results in this news release plus prior holes, there appears to be good potential to mine the area as one enlarged open pit rather than as two separate pits.

Including	100.8	101.6	0.8	26.5

Drilling in this release was focused on 3 objectives: 1) extending the zone at depth, 2) extending the strike or length of the zone and 3) infilling an area between the historical near-surface drilling and McEwen Mining's discovery holes.

1) Drilling Extends Central Zone at Depth - 4.6 gpt gold over 14.0 meters

Holes MLX079, MLX087 and MLX088 targeted mineralization below the initial discovery holes announced on April 11^th, 2013 (Fig. 2, 3 & 4). These new holes successfully extended the zone by 50 meters to a total depth of 180 meters below surface. The zone remains open for further expansion. Significant intercepts include 2.7 gpt gold over 20.2 meters, 2.5 gpt gold over 9.3 meters and 4.6 gpt gold over 14.0 meters. An additional 3 holes have been drilled to extend the zone, with assays pending.

2) Strike (or length of the zone) Extended - 5.7 gpt gold over 23.0 meters

Holes MLX081, MLX085 and MLX090 were drilled southwest and northeast of the initial discovery holes, extending the strike or length of the zone by 30 meters to the northeast and 20 meters to the southwest (Fig. 2). Before drilling began at Central, the distance between the two resources where mining recently commenced was 1,000 meters. Based on these results and prior holes, the Company believes the area can be mined as one enlarged open pit. Highlights from this drilling included 5.7 gpt gold over 23.0 meters, 1.1 gpt gold over 20.5 meters and 3.9 gpt gold over 20.9 meters. An additional 6 holes have been drilled with assays pending.

3) Infilling Gaps & Reducing Strip - 2.5 gpt over 21.2 meters

The last objective with the recent holes was to infill an area between the historic, near surface drilling that tested for gold mineralization down to 20 meters (which encountered weak mineralization) and McEwen Mining's discovery holes, which start 80 meters below surface (Fig. 2, 3 & 4). The three holes from this area were in line with expectations, returning 2.5 gpt gold over 21.2 meters, 1.8 gpt over 12.1 meters and 0.8 gpt gold over 18.7 meters (Fig. 2, 3 & 4). This is an encouraging development as it shows the zone can be extended closer to surface, which should reduce the strip ratio. An additional 2 holes have been drilled with assays pending.

About El Gallo Complex

The El Gallo Complex is located in Sinaloa, Mexico. Phase 1 achieved commercial production in early January. It is forecasted to produce 30,000 ounces of gold per year.

TECHNICAL INFORMATION:

This news release has been viewed and approved by John Read , CPG, McEwen Mining'sconsulting geologist, who is a Qualified Person as defined by National Instrument 43-101 and is responsible for program design and quality control of exploration undertaken by the Company at its Mexican exploration properties. Samples from the core drilling were split on-site at theCompany's El Gallo Complex. One half of the split drill core is shipped to ALS Chemex for sample preparation and analysis by fire assay for gold and 4-acid digestion with ICP determination for silver. Samples returning greater than 10 ppm gold or 1500 ppm silver were re-analyzed using gravimetric fire assay. Standards and blanks were inserted every 20 samples. All holes were drilled with HQ bits and reduced to NTW where required. Samples were taken based on lithologic and/or mineralized intervals and vary in length. The true width of the mineral zone has not been determined.

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.
