  Coeur Reports Healthy Increases in Combined Reserves and Measured and
  Indicated Resources

Business Wire

COEUR D'ALENE, Idaho -- February 15, 2013

Coeur d'Alene Mines Corporation (NYSE:CDE) (TSX:CDM) today announced that the
Company increased its total combined proven and probable reserves and measured
and indicated resources of silver and gold by 17% and 12%, respectively,
resulting in the addition of 85.2 million silver ounces and 462,000 gold
ounces at year-end 2012 over 2011. These gains exclude the 18.0 million ounces
of silver and 226,486 ounces of gold produced during 2012.

The Company’s Rochester mine in Nevada increased silver and gold reserves by
52% and 25%, respectively, over 2011 after producing 2.8 million silver ounces
and 38,071 gold ounces in 2012. As described in the Company’s January 17, 2013
news release, Rochester expects to increase production by 35 - 50% over 2012
based on continued processing of historic stockpiles. These historic
stockpiles contributed to the increases in silver and gold reserves.

At the Palmarejo mine in Mexico, silver and gold measured and indicated
resources grew 169% from 17.0 million to 45.7 million ounces of silver and
370% from 205,000 to 964,000 ounces of gold from 2011 to 2012.

Highlights:
(All comparisons below refer to year-end 2012 compared with year-end 2011)

         and 0.5 million gold ounces

Kensington:

  *Proven and probable reserves declined 24% from 1.3 million gold ounces to
    1.0 million gold ounces
  *Increased definition drilling at a cost of approximately $3.9 million was
    completed and has improved the Company’s overall understanding of the
    Kensington deposit. This will enhance development of a more reliable and
    accurate mine plan and improve exploration targeting.

San Bartolomé:

  *Proven and probable reserves declined 8% from 118.1 million silver ounces
    to 109.1 million silver ounces.
  *Favorable results from the new Pucka Loma target included trench samples
    with silver values averaging 113 grams per tonne (3.3 ounces per ton) over
    an average of four meters (13.1 feet) deep. An initial mineral resource
    estimate of this new zone is expected by mid-year 2013.

Joaquin:

  *Year-end silver measured and indicated resources stood at 65.2 million
    ounces, representing a 70% increase from the September 2012 estimates
    (100% basis) and with a 32% increase in the average silver grade from the
    previous 98 grams per tonne (3.76 ounces per ton) to 129 grams per tonne
    (2.85 ounces per ton).

Lejano:

  *Exploration led to the first estimate of mineral resources at Lejano,
    located in southern Argentina. Measured and indicated resources totaled
    3.0 million silver ounces and 10,000 gold ounces and inferred resources of
    5.7 million silver ounces and 19,000 gold ounces.

Donald J. Birak, Senior Vice President of Exploration for Coeur, said, “Our
2012 exploration program of $40.0 million was successful in cost-effectively
adding approximately 109.6 million silver equivalent ounces of new proven and
probable reserves and new measured and indicated resources, not taking into
account the production of 29.9 million silver equivalent ounces in 2012.^1 We
remain committed to maintaining an aggressive exploration program given the
results achieved through these investments and the opportunities they provide
for further mineral resource and reserve growth.

“During 2013, we plan to invest another $40.0 million in exploration with a
goal to increase mineral resources and to further define our measured,
indicated and inferred resources, which should drive increases in our mineral
reserves. We will focus in 2013 on (i) continuing to drill the historic
stockpiles at Rochester to add low-cost reserves and resources; (ii) expanding
the existing reserves and resources at Palmarejo, including the nearby
Guadalupe and La Patria deposits; (iii) adding high-grade mineral resources at
Kensington; and (iv) expanding the size of the mineral resources at the
Joaquin project in Argentina and (v) exploring for new silver and gold
deposits at all our properties.”

National Instrument 43-101.

Cautionary Statement

This news release contains forward-looking statements within the meaning of
securities legislation in the United States and Canada, including statements
regarding anticipated operating results, production levels, initial mineral
resource estimates and future reserve and resource additions. Such
forward-looking statements involve known and unknown risks, uncertainties and
other factors which may cause Coeur's actual results, performance or
achievements to be materially different from any future results, performance
or achievements expressed or implied by the forward-looking statements. Such
factors include, among others, the risks and hazards inherent in the mining
business (including environmental hazards, industrial accidents, weather or
geologically related conditions), changes in the market prices of gold and
silver, the uncertainties inherent in Coeur's production, exploratory and
developmental activities, including risks relating to permitting and
regulatory delays and disputed mining claims, any future labor disputes or
work stoppages, the uncertainties inherent in the estimation of gold and
silver ore reserves, changes that could result from Coeur's future acquisition
of new mining properties or businesses, reliance on third parties to operate
certain mines where Coeur owns silver production and reserves, the loss of any
third-party smelter to which Coeur markets silver and gold, the effects of
environmental and other governmental regulations, the risks inherent in the
ownership or operation of or investment in mining properties or businesses in
foreign countries, Coeur's ability to raise additional financing necessary to
conduct its business, make payments or refinance its debt, as well as other
uncertainties and risk factors set out in filings made from time to time with
the United States Securities and Exchange Commission, and the Canadian
securities regulators, including, without limitation, Coeur's most recent
reports on Form 10-K and Form 10-Q. Actual results, developments and
timetables could vary significantly from the estimates presented. Readers are
cautioned not to put undue reliance on forward-looking statements. Coeur
disclaims any intent or obligation to update publicly such forward-looking
statements, whether as a result of new information, future events or
otherwise. Current mineralized material estimates include disputed and
undisputed claims at Rochester. While the Company believes it holds a superior
position in the ongoing claim dispute, the Company believes an adverse legal
outcome would cause it to modify mineralized material estimates. Additionally,
Coeur undertakes no obligation to comment on analyses, expectations or
statements made by third parties in respect of Coeur, its financial or
operating results or its securities.

Donald J. Birak, Coeur's Senior Vice President of Exploration and a qualified
person under Canadian National Instrument 43-101, supervised the preparation
of the scientific and technical information concerning Coeur's mineral
projects in this news release. For a description of the key assumptions,
parameters and methods used to estimate mineral reserves and resources, as
well as data verification procedures and a general discussion of the extent to
which the estimates may be affected by any known environmental, permitting,
legal, title, taxation, socio-political, marketing or other relevant factors,
please see the Technical Reports for each of Coeur's properties as filed on
SEDAR at www.sedar.com.

Cautionary Note to U.S. Investors-The United States Securities and Exchange
Commission permits U.S. mining companies, in their filings with the SEC, to
disclose only those mineral deposits that a company can economically and
legally extract or produce. We may use certain terms in public disclosures,
such as "measured," "indicated," "inferred” and “resources," that are
recognized by Canadian regulations, but that SEC guidelines generally prohibit
U.S. registered companies from including in their filings with the SEC. U.S.
investors are urged to consider closely the disclosure in our Form 10-K which
may be secured from us, or from the SEC's website at http://www.sec.gov.

Non-U.S. GAAP Measures

We supplement the reporting of our financial information determined under
United States generally accepted accounting principles (U.S. GAAP) with
certain non-U.S. GAAP financial measures, including cash operating costs,
operating cash flow, adjusted earnings, and EBITDA. We believe that these
adjusted measures provide meaningful information to assist management,
investors and analysts in understanding our financial results and assessing
our prospects for future performance. We believe these adjusted financial
measures are important indicators of our recurring operations because they
exclude items that may not be indicative of, or are unrelated to our core
operating results, and provide a better baseline for analyzing trends in our
underlying businesses. We believe cash operating costs, operating cash flow,
adjusted earnings and EBITDA are important measures in assessing the Company's
overall financial performance.

Notes to the above Mineral Reserves and Resources:

^1.  ^Effective December 31, 2012.
      ^Metal prices used for mineral reserves were $33.00 per ounce of silver
      and $1,700 per ounce of gold, except Endeavor, at $2,200 per metric ton
^2.   of lead, $2,200 per metric ton of zinc and $34.00 per ounce of silver.
      Metal prices used for mineral resources were $33.00 per ounce of silver
      and $1,700 per ounce of gold, except Endeavor, at $2,200 per metric ton
      of lead, $2,200 per metric ton of zinc and $34,00 per ounce of silver.
^3.   ^Palmarejo mineral resources are the addition of Palmarejo, Guadalupe
      and La Patria (Measured, Indicated and Inferred).
^4.   ^Mineral Resources are in addition to mineral reserves and have not
      demonstrated economic viability.
      ^Current mineral resources were inclusive of disputed and undisputed
^5.   claims at Rochester. While the Company believes it holds a superior
      position in the ongoing claims dispute, the Company believes an adverse
      legal outcome would cause it to modify mineral resources.
      ^Rounding of tons and ounces, as required by reporting guidelines may
^6.   result in apparent differences between tons, grade and contained metal
      content.
      ^For details on the estimation of mineral resources and reserves for
^7.   each property, please refer to the relevant Technical Report on file at
      ^www.sedar.com^.
