Copper Mineralization Extension


Western Copper Corporation ("Western Copper" or the "Company") (TSX: WRN)
is pleased to announce the final results from the 2010 exploration
program at its wholly owned Casino Project, located in the Yukon.

The 2010 drill program completed in August confirmed the flat-lying,
shallow copper and gold enriched supergene zone extends over 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 drilling is 85 m. The copper and
gold enriched zone remains open to the north for further expansion.

Notable results from the 14 holes drilled since the last update include
hole CAS-074 with 241.9 m of 0.80 CuEq, which continued the expansion of
the supergene zone to the southwest. Expanding the zone to the still open
north is hole CAS-079 with 30.0 m of 0.45 CuEq.

Additional infill drilling was also completed as part of this drilling
campaign which confirmed the excellent grades through the supergene and
hypogene zones in the south of the deposit with CAS-082 returning 117.0 m
of 0.87 CuEq in the supergene and 226.2 m of 0.56 CuEq in the hypogene.

Highlights of the holes drilled and assayed since the last press release
are summarized in Table 1 and a complete listing of drill-holes and
results drilled in 2010 are shown in Table 2.

Western Copper has now completed 26,400 m of new drilling since the
pre-feasibility was completed in 2008. Nearly all of the new drilling has
been drilled in areas outside of the previously defined area of
mineralization or in areas previously considered waste.

"The expansion of the higher grade, near surface supergene mineralization
into areas previously thought to waste should positively impact the
economics of the Casino deposit by lowering the stripping ratio," said
Dale Corman, Chairman & CEO, "This higher grade supergene gold and copper
mineralization remains open to the north showing there is further
potential to improve both the size of the supergene mineralization and
the economics of the project."

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.

Scott Casselman, P.Geo., is the qualified person responsible for the
execution of the Casino Project exploration program and the preparation
of the technical information in this news release.

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.
