Coeur′s Rochester Mine Receives Positive BLM Decision Allowing for Extended Mining Operations and Increased Production

Coeur d′Alene Mines Corporation (NYSE:CDE) (TSX:CDM) (ASX:CXC) announced
today that the Bureau of Land Management has issued a positive Decision
Record (DR) for Coeur′s Rochester Mine in Nevada to extend silver and
gold mining operations by several years with new production ounces
expected to begin being recovered in the fourth quarter of 2011.

Work on the construction of a new leach pad and related infrastructure
is expected to begin in the first quarter of 2011 with capital costs
estimated to total approximately $29 million in 2011 and $38 million
over the life of the project. This extension will increase total average
annual silver and gold production to over 2.4 million ounces and 35,000
gold ounces over several years. This production profile represents a
substantial increase compared to current expected annual production
levels through 2014 of 700,000 ounces and 5,000 ounces of silver and
gold, respectively, from existing residual leaching operations.

At the beginning of 2010, Rochester contained proven and probable
reserves measuring 25.9 million ounces of silver and 232,000 ounces of
gold. A recently completed and updated feasibility study on the
expansion plan includes 27.6 million contained ounces of silver and
247,000 contained ounces of gold within 48.3 million leach tons at
average grades of 0.57 ounces of silver per ton and 0.005 ounces of gold
per ton, based on metal prices of $1,205 per ounce of gold and $16.25
per ounce of silver (see table on last page of release). Expected cash
flow and production is incremental to the ounces and cash flow currently
being generated by ongoing residual leaching activities.

The expansion is expected to add approximately 200 jobs, providing a
boost to the Nevada economy. In addition, the mine recently received
awards from the Nevada Mining Association and the Mine Safety and Health
Administration for safe operations. The mine currently has exceeded
1,224 days without a lost-time accident.

Rochester′s 2010 production forecast is expected to be 2.0 million
silver ounces and 10,000 gold ounces at an average cash cost of
approximately $3.00 per silver ounce.

Rochester has produced over 127.6 million ounces of silver and over 1.4
million ounces of gold in its 25 years of operations.
