McEwen Mining Inc.: El Gallo Regional Exploration; Twin Domes Drilling 
Intersects Significant Near Surface Gold Mineralization 
9.7 gpt Gold over 10.3 Meters - 17 Meters below Surface 
5.0 gpt Gold over 16.8 Meters - 7 Meters below Surface 
TORONTO, ONTARIO -- (Marketwired) -- 08/19/13 -- McEwen Mining Inc.
(NYSE:MUX)(TSX:MUX) is pleased to announce core drill results from
its new Twin Domes discovery, including 9.7 gpt gold over 10.3 meters
and 5.0 gpt gold over 16.8 meters. These results are a follow-up to
the discovery holes announced in April, which intersected 8.8 gpt
gold over 9.7 meters and 9.8 gpt gold over 4.6 meters, in addition to
a trench that returned 20.9 gpt gold over 12.7 meters. The Company
believes Twin Domes is attractive due to its higher gold grades and
its close proximity to the Company's process plant. 
Twin Domes is located 17 kilometers (10.5 miles) northwest of the
Company's El Gallo 1 heap leach mine (Fig. 1). Initial test results
show that the gold mineralization at Twin Domes is potentially
amenable to heap leaching, which would allow it to be processed at El
Gallo 1. Ten additional core holes were completed in this recent
drilling. Although it is early, McEwen Mining is highly encouraged by
these results and believes Twin Domes could have a positive impact on
the El Gallo 1 mine. Highlights are shown below.

See Table 2 for details of all recently drilled holes from Twin Domes.

 
To date, gold mineralization at Twin Domes has been identified from
surface to a depth of 45 meters. The known length (or strike) of the
zone is approximately 275 meters. A total of 20 additional core holes
have been planned in order to follow up on these results. This
program will start next week.

TECHNICAL INFORMATION: 
This news release has been viewed and approved by John Read, CPG,
McEwen Mining's consulting 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 the Company's El Gallo 1 mine. 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. Samples were analyzed by ALS Chemex using the same methods as
for drill core samples. The true width of the mineral zones has not
been determined.
