Prosperity Panel Review Hearings Complete

May 6, 2010

Vancouver, BC - Taseko Mines Limited (TSX: TKO; NYSE Amex: TGB) (“Taseko” or the “Company”) announces that six weeks of Federal Panel Review Hearings into the Company’s Prosperity Gold-Copper Project (the “Project”) have now concluded, the record has been closed and no additional information will be considered by the Panel. The Panel has 60 days to prepare its report for submission to the federal Minister of the Environment and other agencies - no later than July 2, 2010 - as directed by its Terms of Reference. The Minister will then take the matter to the federal Cabinet for a final decision.

“All potential environmental effects were examined by the responsible federal departments, agencies and authorities and based on the evidence and findings presented during these past 6 weeks of hearings, and we remain fully confident that the Cabinet will grant approval for mine development,” said Russell Hallbauer, President and CEO. “After hearing all of the evidence, our position remains that there are no significant environmental effects after taking the mitigation measures into account,” added Mr. Hallbauer.

Health Canada is satisfied that there are no human health effects or any ecological health concerns associated with building and operating this mine. Both Environment Canada and Natural Resources Canada agree with Taseko’s findings concerning water quality and aquatic ecology. On the matter of compensation for impacts on fish habitat, the Company and the Department of Fisheries and Oceans continue to work cooperatively towards resolving any outstanding issues.

Taseko’s closing submission to the Panel emphasized some key points, including the economic and social needs of the region, an area in which over the last year consumer bankruptcies have increased by 70 percent, the unemployment rate has increased 84 percent and, in Williams Lake, the residential rental vacancy rates have increased 700 percent. The closing submission is posted on the Taseko website www.tasekomines.com under Events and the Prosperity Project website www.prosperityproject.ca under What’s New.

The area where the proposed Prosperity Mine is located is not subject to aboriginal title; it is Crown land, owned and regulated by the Province of British Columbia which issued the Project an Environmental Assessment Certificate and approved the Project for development on January 14, 2010.
