NEWS RELEASE

Coeur Reports Steady First Quarter Production and Reaffirms Full-Year Production Guidance

Production levels expected to accelerate during remaining three quarters of 2013

Growing contribution from gold relative to silver as gold production rises at U.S. operations

Coeur d'Alene, Idaho - April 15, 2013 - Coeur d'Alene Mines Corporation (the “Company” or “Coeur”)(NYSE: CDE, TSX: CDM) announced it produced 3.8 million ounces of silver and 56,913 ounces of gold during the first quarter of 2013. The Company also reaffirmed its full year production guidance of 18.0-19.5 million ounces of silver and 250,000-265,000 ounces of gold in 2013. Coeur will report its full operating and financial results on May 9, 2013.

First Quarter Operating Highlights

• Companywide silver production of 3.8 million ounces was 22% lower than the first quarter 2012 due to lower grade ore processed from both open pit and underground operations at the Company's Palmarejo mine.

• Companywide gold production of 56,913 ounces was 30% higher than the first quarter 2012 due to significantly higher production from the Company's Kensington and Rochester mines.

• Metal sales were $178.6 million, down 13% compared with the first quarter 2012.

• Average realized silver and gold prices were $30.61 per ounce and $1,630 per ounce, respectively, representing decreases of 6% and 4%, respectively, compared with the first quarter of 2012.

• Grades and mining rates rebounded at Palmarejo late in the first quarter compared to the third and fourth quarters of 2012. Palmarejo produced 1.6 million ounces of silver and 22,965 ounces of gold in the first quarter 2013. While lower than first quarter 2012 levels, silver and gold production was 6% and 15% higher, respectively, compared to the fourth quarter 2012. Production rates are expected to climb in the second half of 2013.

• San Bartolomé produced 1.4 million ounces of silver, which was 12% lower than the first quarter of 2012 due to lower silver grades, but the mine performed better than planned and this level should reflect anticipated production rates during the remainder of the year.

• Rochester's production was temporarily affected by extremely cold temperatures and heavier than normal snowfall during January and February, which impacted ore crushing. Rochester produced 0.6 million ounces of silver and 8,742 ounces of gold, which was lower than production in the fourth quarter 2012, but 47% and 65% higher than the first quarter 2012, respectively.

• Kensington's gold production more than tripled compared to the first quarter of 2012, reaching 25,206 ounces. Kensington's production is expected to increase in the second half of 2013 over the first half of 2013 due to anticipated improved grades and higher throughput rates.

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. 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 is an important measure in assessing the Company's overall financial performance.
