TASEKO SIGNS SIX-YEAR, FIXED-RATE TREATMENT AND REFINING AGREEMENT

April 21, 2008, Vancouver, BC - Taseko Mines Limited (TSX: TKO; AMEX: TGB) is pleased to announce that it has entered into a six-year agreement with MRI Trading AG, a Swiss-based metal trading house, for the treatment and refining of Gibraltar copper concentrate. Under the terms of the agreement, Taseko has secured long-term, fixed, low cost rates for processing six years of Gibraltar mine production, or approximately 1.1 million tons of copper concentrate production, into copper metal.
 
Within the framework of this treatment and refining agreement, Taseko has also secured a US$30 million Line of Credit, to add to its $53 million on hand.
 
Taseko will continue to have the ability to sell copper metal at market prices.
 
Russell Hallbauer, President and CEO of Taseko stated, "The finalization of this new agreement has taken well over a year and has included many bidders. The agreement that we have negotiated reflects the tightness of the concentrate market where many smelters are trying to source from limited concentrate supply."
 
Mr. Hallbauer continued, "Gibraltar produces one of the highest quality copper concentrates in the world which is reflected by the financial terms for processing our concentrate and the Line of Credit that has been secured. Stabilization of our treatment and refining costs for a period of six years is an important step as we continue to build our business and decrease Gibraltar's cost structure while providing superior returns to our shareholders."
