Western Copper Enters Into Arrangement Agreement to Spin Out Assets to Shareholders and Announces Name Change

VANCOUVER, BRITISH COLUMBIA -- (Marketwire - Aug. 19, 2011) - Western Copper Corporation ("Western Copper" or the "Company") (TSX:WRN) (NYSE Amex:WRN) is pleased to announce that, further to its news release dated June 23, 2011, the Company has entered into an arrangement agreement dated August 18, 2011 (the "Agreement") with certain of its wholly-owned subsidiaries including Copper North Mining Corp. ("SpinCo. A") and NorthIsle Copper and Gold Inc. ("SpinCo. B"), both of which were incorporated for the purposes of the Agreement, to give effect to the spin-out transaction announced on June 23, 2011.

Additionally, as part of the arrangement agreement, the Company will change its name from "Western Copper Corporation" to "Western Copper and Gold Corporation".

"This spin-out arrangement should work to better define the value of the excellent portfolio of assets we have in Western Copper," said Dale Corman, Chairman and Chief Executive Officer. "And after the spin-out, with Casino as the sole asset in the Company, we believe that a name change to 'Western Copper and Gold' better reflects the significant amount of gold contained in Casino and the high percentage that gold contributes to the project's revenue."

The Agreement, a copy of which will be available under Western Copper's profile on SEDAR, sets out the terms of the statutory plan of arrangement (the "Arrangement") involving Western Copper, its securityholders, SpinCo. A, SpinCo. B and certain of Western Copper's direct and indirect subsidiaries, which will involve, among other things:

- a series of vertical short form amalgamations involving Western Copper and certain of its subsidiaries, including the vertical short form amalgamation of Western Copper with certain of its subsidiaries to form "Western Amalco";

- changes to the charter documents of Western Copper, including the change of its name to "Western Copper and Gold Corporation";

- the transfer of 100% of Western Copper's interest in the Carmacks Copper Project located in the Yukon Territory, Canada, as well as the Redstone Project located in the Northwest Territories, Canada to SpinCo. A;

- the transfer of 100% of Western Copper's interest in the Island Copper Project located on Northern Vancouver Island, British Columbia, Canada to SpinCo. B;

- the transfer from Western Copper of $2 million to SpinCo. A and $2.5 million to SpinCo. B; and

- certain exchanges of securities.

The Arrangement, if completed, will result in shareholders of Western Copper as at the effective date of the Arrangement (the "Effective Date") being entitled to receive, for each common share of Western Copper (a "Western Copper Share") held as at such date:

i. one post-Arrangement common share of Western Copper (a "Western Amalco Share")

ii. 0.5 of a common share of SpinCo. A (a "SpinCo. A Share"); and

iii. 0.5 of a common share of SpinCo. B (a "SpinCo. B Share").

Holders of outstanding Western Copper warrants ("Warrants") immediately prior to the Effective Date will receive, upon exercise of each such Warrant at the same original exercise price and in accordance with the terms of such Warrant: (i) one Western Amalco Share; (ii) 0.5 of a SpinCo. A Share; and (iii) 0.5 of a SpinCo. B Share, all in lieu of the one Western Copper Share that was issuable upon exercise of such Warrant immediately prior to the Effective Date.

Each of SpinCo. A and SpinCo. B intends to seek a listing of SpinCo. A Shares and SpinCo.B Shares respectively on the TSX Venture Exchange following the completion of the Arrangement.

Western Copper will be seeking shareholder approval of the Arrangement at the upcoming special meeting of shareholders scheduled to be held on or about September 21, 2011, in accordance with the terms of the Agreement and the Business Corporations Act (British Columbia). The Arrangement will also be subject to, among other things, approval of the Toronto Stock Exchange, TSX Venture Exchange and the Supreme Court of British Columbia.

Full details of the proposed spinout transaction will be contained in a notice of meeting, information circular and supporting documents describing the Arrangement, which will be mailed to shareholders and filed on SEDAR in due course.
