Yesab Responds to Public Comments on the Carmacks Copper Project

Western Copper Corporation (the “Company”) announces that the Yukon Environmental and Socio-economic Assessment Board (YESAB) requires further clarification from the Company in order to complete the final Screening Report and Recommendation on the Carmacks Copper Project.

YESAB issued the draft Screening Report for public comment on December 17, 2007 and requested that comments be submitted by February 6, 2008.

Following its review of public comments, YESAB has determined that further clarification is required from the Company and issued a Supplementary Information Request on February 27, 2008.

Western Copper expects to submit the additional information to YESAB within the next month, subject to receipt from YESAB of the technical details supporting this Supplementary Information Request.

Based on discussions with YESAB, the Company believes that production of the final Screening Report will take approximately two months following the submission of the additional information.

Western Copper has updated the Carmacks Copper Project development schedule to reflect to the new permitting timeframe. Due to the permitting delay, the Company expects that at best only a limited amount of construction could now take place in 2008 and that copper production will commence in the second half of 2010.

On behalf of the board,
