Illegal Employee Disruption Causes Temporary Shut-Down at Coeur d′Alene Mines′ Palmarejo Mine

A small, unorganized group of employees of a subsidiary of Coeur
Mexicana last weekend blocked access to Coeur d′Alene Mines′ (NYSE:CDE,
TSX:CDM) Palmarejo Mine located in the state of Chihuahua in northern
Mexico. Palmarejo management supervised an orderly, temporary shut-down
of the mine and mill in order to allow for dialogue with employees while
ensuring the safety of workers at the mine site. Management considers
the actions taken by the small group blocking access to the mine to be
illegal.

The small group blocking access to the mine does not represent Palmarejo
Mine employees as a whole; however their actions are preventing other
employees from safely reporting to work. The group of employees did not
raise their concerns with Palmarejo management in any way before
blocking access to the mine. Management′s attempts to resolve the issue
through discussions were unsuccessful. Mine management has requested
assistance from Chihuahuan government authorities to help resolve the
situation.

At this time, the Company does not anticipate the temporary shut-down to
have a material impact on 2012 production at Palmarejo.
