NEWS RELEASE

Coeur d’Alene Mines to Present at PDAC in Toronto, March 3, 4 & 6

COEUR D’ALENE, Idaho - March 1, 2013 - Coeur d’Alene Mines Corporation (NYSE:CDE, TSX:CDM), announced today that three of its senior staff will make presentations at the Prospectors & Developers Association of Canada (PDAC) international convention in Toronto.

Humberto Rada, President of Coeur Manquiri in Bolivia, will present on Sunday, March 3 at 1:00 p.m. ET at the Metro Toronto Convention Centre, South Building, Room 803AB. Mr. Rada’s presentation, part of PDAC’s CSR Event Series, will focus on Coeur d’Alene Mines’ successful approach to addressing the unique challenges of operating its San Bartolomé silver mine near the community of Potosi, Bolivia. Mr. Rada will discuss how developing strong partnerships and stakeholder alliances in Bolivia has reduced operational risk and reinforced Coeur’s social license to operate.

Wendy Yang, Coeur’s Vice President of Investor Relations, will speak on Monday, March 4 at 2:40 p.m. ET at the Convention Centre, South Building, Room 803AB, Silver Session 2. Ms. Yang will provide an overview of Coeur’s strong production and cash flow position, building value per share as a leading growth-oriented silver producer and of the Company’s pending acquisition of Orko Silver Corp. Both presentations will be available on the Company’s website at www.coeur.com.

Paul Hohbach, Coeur’s Director of Exploration, will present during the Silver Session on Wednesday, March 6 at 10:50 a.m. ET at the Convention Centre, South Building in Room 713. Mr. Hohbach will present a paper co-authored by his Coeur colleagues Sadae Lortz and Carlo Nasi, titled Major Silver Districts of the Western United States: Their importance relative to past and current North American Production. This paper highlights current major silver mines in the western United States, including Coeur’s longest running operation, the Rochester silver-gold mine in Nevada, which is ramping up silver production 35-50% in 2013.

Coeur invites shareholders and others to visit its booth, #2421B at the same location on Tuesday and Wednesday, March 5-6, to meet with Coeur staff and learn more about the Company. Exhibit hours are from 10 a.m. to 5:30 p.m. ET on Tuesday March 5, and from 9 a.m. to noon ET on Wednesday March 6.
