"Our first quarter operational performance represents a solid start to the year," stated Mitchell Krebs, Coeur's President and Chief Executive Officer. "In particular, we are pleased with the progress at our Rochester mine, where daily silver production rates have exceeded 13,000 ounces in early April. We anticipate higher silver and gold production levels from Rochester in each successive quarter during the remainder of 2014.

"With our four major mines operating consistently, our cost reduction initiatives gaining momentum, minimal required capital projects, and a bolstered liquidity position, we believe we are well-positioned for a successful year," Mr. Krebs concluded.
