Western Copper Extends Higher Grade Supergene Mineralization at Casino

VANCOUVER, B.C. Western Copper Corporation (“Western Copper” or the “Company”) (TSX:WRN) is pleased to announce preliminary results from the 2010 exploration program at its wholly owned Casino Project, located in the Yukon.

Drilling at Casino has extended the flat-lying, shallow copper and gold enriched supergene zone to a 2.0 km by 1.2 km area – a significant expansion over its previously outlined extent as identified in the 2008 Pre-feasibility Study (Figure 1). The average core length of the supergene from the current drilling is 80 m. The copper and gold enriched zone remains open to the north for further expansion.

Highlights of the 33 holes drilled and assayed during the 2010 campaign are summarized in Table 1 and a complete listing of drill-holes and results are shown in Table 2. Hole locations are shown on Figure 1.

Hole CAS-073 is of particular interest. In addition to the 114 m of 0.97% copper equivalent mineralization in the supergene zone, it also contains 110 m of copper, gold and molybdenum mineralization at a copper equivalent grade of 0.69% in the hypogene zone.

Western Copper has now completed 20,000 m of new drilling since the pre-feasibility was completed in 2008. An additional 6,000 m of drilling is planned for the remainder of 2010 and is expected to be complete by mid-August. All of the new drilling has been drilled in areas outside of the previously defined area of mineralization or in areas previously considered waste.

“We believe the discovery of significant additional near surface supergene mineralization has the potential to considerably improve the project’s economics” said Dale Corman, Chairman & CEO “The newly discovered mineralization with overall higher grades would be extracted and processed during the first years of the mine life and much of it occurs in areas of the pit previously thought to be waste material and should result in a lower stripping ratio”

The Casino project is located 380 km northwest of Whitehorse, Yukon and has a NI 43-101 compliant reserve estimate containing 8 million oz of gold, 4.4 billion lb of copper, and 475 million lb of molybdenum, contained in approximately 1 billion tonnes of ore.

QA/QC including assurance of chain of custody has been implemented in accordance with industry best practices. Split core samples are prepared and analyzed by ALS Chemex. Prepared samples are initially run using a four acid digestion process and conventional multi-element ICP-AES analysis. Additional assaying for total copper and molybdenum is run using a 4 acid digestion – AES or AAS method to a 0.001% detection limit. Gold assays are run using 30 gram sample fire assay with an AA finish to a 0.005 ppm detection limit. The QA/QC procedure involves regular submission of Certified Analytical Standards and blanks and property specific duplicates, with check assaying performed by Acme Analytical Laboratories Ltd.
