Public Online Information Resource Launched to Promote Open Discussion

Vancouver, BC - Taseko Mines Limited (TSX: TKO; NYSE Amex: TGB) (“Taseko” or the “Company”) has submitted a revised project description to the Federal Government in pursuit of final approval of its New Prosperity Gold-copper Project.

The New Prosperity project addresses the concerns identified during the original federal review process while building on the core strengths and benefits of the original Prosperity proposal. The new proposal preserves Fish Lake and limits the impact to the environment. It aims to relieve concerns of the First Nations and the federal Panel while at the same time delivering significant economic value to British Columbia and Canada.

“We have made significant efforts to address all the necessary requirements for final federal approval. Preserving Fish Lake, which adds $300 million in capital and operating expense to the project is an example of that effort and a reflection of the depth of our commitment to the success of New Prosperity and to the principles of sustainability,” says Taseko President & CEO Russell Hallbauer.

“Prosperity is the 7th largest undeveloped gold-copper porphyry deposit in the world and as such has the ability to deliver economic value and social benefit on a national scale. We are looking forward to delivering the potential of this project for Canadians, including all levels of Government, First Nations communities, the people of the Cariboo and our shareholders,” concluded Mr. Hallbauer.

Taseko is launching an in-depth online information portal (http://www.newprosperityproject.ca). The site encourages public dialogue and represents a progressive approach to community engagement.
