McEwen Mining Celebrates Its First Year of Production 
105,050 Gold Eq. oz Produced in 2012 
2013 Production Forecast to grow by 24% 
TORONTO, ONTARIO -- (Marketwire) -- 01/15/13 -- McEwen Mining Inc.
(NYSE:MUX)(TSX:MUX) is pleased to announce the results of its first
year of production and for its Fourth Quarter 2012. For the full-year
2012, the Company produced 105,050 gold eq. oz (48,876 gold oz and
2,921,242 silver oz) and in Q4 produced 32,220 gold eq. oz (17,578
gold oz and 761,377 silver oz). Silver production has been converted
into gold equivalent ounces (gold eq. oz) based on a 52:1 ratio.  
Production costs for 2012 and cost guidance for 2013 will be reported
in March with year-end financials. Production in 2013 is forecasted
to grow by +24% to 130,000 gold eq. oz (72,310 gold oz and 3,000,000
silver oz) with production coming from 2 mines: San Jose and El Gallo
1. El Gallo 1 in Mexico commenced commercial production on January
1st, 2013.  
"2012 was a transformative year. It started in January, when McEwen
Mining was created with the combination of US Gold and Minera Andes.
We saw strength in the combination through the diversification and
growth of our production base. At mid-year, our exploration success
was highlighted by an increase in our estimated gol
d, silver and
copper resources. Our second mine, El Gallo, was built on budget and
on time and has reached commercial production. El Gallo 2 is in the
permitting phase and we hope to have the necessary permits to start
construction during Third Quarter of this year. Our partner and the
operator the San Jose mine, Hochschild Mining, has been doing an
excellent job managing the mine and increasing production. We
continue to advance the permitting process of our Gold Bar project in
Nevada, and hope to receive construction permits in 2014. Late in the
year, we announced a settlement of the lawsuit on our Los Azules
property and began an aggressive exploration program there. Initial
exploration results and an updated resource estimate will be released
by the end of January. Before year-end, we also successfully
completed a $60 million Rights Issue, which will provide the
necessary funds to start development of El Gallo 2. Over the next 3
years, we forecast our internal projects will increase our production
from 100,000 gold eq. oz to 290,000 gold eq. oz, a 3-fold increase.
During this time, we will also be looking for opportunities to
further increase our production in order to advance on our goal of
qualifying for inclusion in the S&P 500 Index," said Rob McEwen,
Chief Owner.

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

Instrument 43-101 "Standards of Disclosure for Mineral Projects"
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 Canadian 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 gre
ater 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
