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

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.

• 
  Proven and probable silver reserves increased 52% from 29.6 million
  ounces to 44.9 million ounces
  
• 
  Proven and probable gold reserves increased 25% from 247,000 ounces to
  308,000 ounces
  

Palmarejo:

    Initial indicated resources at La Patria of 9.8 million silver
    ounces 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 Bartolom?:

• 
  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.?
