Taseko Mines Limited: Electrical Transformer Failure at Gibraltar Mine

Market Wire, May, 2008

Taseko Mines Limited ("Taseko" or the "Company") (TSX: TKO)(AMEX: TGB) announces that an electrical transformer supplying power to the concentrator facility at its Gibraltar Mine has failed. The cause of the failure is being investigated.

A replacement transformer has been sourced and is being readied for shipment to the Gibraltar Mine. Copper production will be curtailed for approximately two weeks until the new transformer is operational.

Russell E. Hallbauer, President and CEO of Taseko, commented, "This transformer failure is an extremely unfortunate event for the mine as our operations team have been making significant strides in getting our SAG mill up to full capacity. While immediate metal production will be impacted, the mine will continue waste stripping and pit development sequencing and the SX-EW plant will continue to produce copper cathode. Our operational objectives of achieving daily throughput of 55,000 tons per day are on time and the schedule will not be affected by this power outage."

Russell Hallbauer, President and CEO
