-- Significant Impact to Companywide Reserves, Cash Flow and Production --

COEUR D'ALENE, Idaho -- Coeur d'Alene Mines Corporation (NYSE:CDE)(TSX:CDM)(ASX:CXC) today announced results from the completed feasibility study for its Palmarejo silver/gold open pit/underground project in Mexico.

This study reflects results from geologic, engineering and economic analyses for only the Palmarejo deposit, which is one of three large silver and gold deposits identified to-date in the district. The Company plans to update this study later this year, which it expects will further increase mineral reserves, mineral resources, production levels, mine life and cash flow.

The following tables summarize the Palmarejo estimated reserves, resources, production and cash flows and their impact to expected companywide levels. Initial reserves at Palmarejo have increased total companywide reserves 29% to 278.8 million. Production, beginning in the first half of 2009, is expected to increase companywide silver production 28% next year to an estimated 23.6 million ounces. 2009 operating cash flow from Palmarejo is anticipated to add $116.0 million to Coeur's total expected operating cash flow of $120 million for total projected 2009 operating cash flow of $236.0 million based on a $17/oz silver price and $850/oz gold price.

"We are pleased to announce the completion of the feasibility study for the initial phase of our Palmarejo project, our next major new mine and one of the largest and highest-quality advanced silver/gold projects in the world," said Dennis E. Wheeler, Chairman, President and Chief Executive Officer. "Construction remains on-schedule with an expected first-half 2009 startup. Once in production, Palmarejo will add significantly to Coeur's growing silver and gold production profile, reduce companywide cash costs, and substantially boost our cash flow. In addition, we look forward to reporting continued increases to Palmarejo's reserves and resources as our drilling programs continue, which will continue to generate additional value and lead to more years of silver and gold production at Palmarejo."

Donald Birak, Senior Vice President of Exploration for Coeur added, "These new proven and probable mineral reserve results are just for the Palmarejo deposit, one of the three large mineral deposits identified to-date - Palmarejo, Guadalupe and La Patria - in this large and prospective property. We expect to increase these initial reserves during the remainder of the year, and beyond, through continued exploration on the district's multiple exploration targets. New mineral resource models are currently underway for both the Guadalupe and La Patria silver and gold-bearing structures and are expected to contribute to future mineral reserves through additional drilling and engineering analysis."
