News Releases

VANCOUVER, BRITISH COLUMBIA — Western Copper Corporation (“Western Copper” or the “Company”) (TSX: WRN) is pleased to provide a progress update on the revised Pre-Feasibility Study currently in progress for its wholly-owned Casino Gold-Copper Project, located in the Yukon Territory. Metallurgical testing, currently underway at G&T Metallurgical Services Ltd., indicates that the mill throughput can be increased to 120,000 tonnes per day (“tpd”), without significant losses in recovery or major changes to the milling circuit. This is an increase of 33% from the 90,000 tpd rate proposed in the Pre-Feasibility Study completed in 2008. This throughput increase is a result of coarsening the primary grind.

It is expected that this throughput increase will have only a minor impact on the overall capital costs as there are only minimal changes to the milling circuit required to achieve this throughput. The throughput increase should also result in lower operating costs per tonne.

A new Casino reserve calculated from the updated resource reported in November 2010 is the key driver for updating the Pre-Feasibility Study. In addition to incorporating the new reserve and increasing the throughput, the new study will add silver recovery, update capital and operating costs, and include natural gas fired power as the primary power option.

“Early indications are that the new information we have about the Casino project should significantly improve project economics,” said Dale Corman, Chairman and CEO of Western Copper.
