September 6, 2007 - Taseko Mines Limited ("Taseko" or the "Company") (TSX: TKO; AMEX:TGB) announces that the recently completed 2007 drilling program at its 100% owned Gibraltar Copper-Molybdenum Mine has resulted in an addition of 128 million tons to the mineral reserves. As a result, the total mineral reserves at Gibraltar have increased to 384 million tons at 0.310% copper and 0.009% molybdenum, containing 2.4 billion pounds of copper and 69 million pounds of molybdenum. In addition to the 384 million tons of proven and probable reserves, there are more than 500 million tons of measured and indicated resources at a similar grade.

The Gibraltar concentrator is undergoing a major 2-phase expansion which will be complete by the end of 2008. The increase in the mineable tonnage will allow the expanded milling operations to be maintained at 55,000 tons per day for 17 years, averaging 115 million pounds of copper and 1.4 million pounds of molybdenum per year, which will make Gibraltar the second largest open pit copper mine in Canada. Russell Hallbauer, President and CEO of Taseko, commented, "These new mineral reserves plus the more than 500 million tons of measured and indicated resources, in combination with the nearly complete mill expansion, puts Taseko at the forefront of Canadian mining companies." Mr. Hallbauer continued, "The reserves and resources at Gibraltar and the one billion tonnes of reserves and resources at the Company's Prosperity Gold-Copper Project 1 contain 11.0 billion pounds of copper, all located in the mining-friendly jurisdiction of British Columbia, creating vast opportunities for the Company and setting Taseko apart from its peers."

Gibraltar's proven and probable reserves as of September 30, 2007 are tabulated below:

1 Prosperity has proven and probable reserves of 480 million tonnes grading 0.43 g/t gold and 0.22% copper (at a $4.00 NSR/tonne cut-off), based on a pre-feasibility study (see Taseko's January 10, 2007 news release), included within 1.0 billion tonnes of measured and indicated resources grading 0.41 g/t gold and 0.24% copper at a 0.14% copper cut-off. Scott Jones, P.Eng., is the qualified person for the Prosperity Project. 2 Based on reconciliation with projected mineral reserves at Taseko's fiscal year end at current production rate of 33,500 tons per day. In addition to the above mineral reserves, Gibraltar has the following mineral resources:

The mineral resource and reserve estimations were completed by Gibraltar mine staff under the supervision of Ian S. Thompson, P.Eng., Superintendent of Engineering and a Qualified Person under National Instrument 43-101. Mr Thompson has verified the methods used to determine grade and tonnage in the geological model, reviewed the long range mine plan, and directed the updated economic evaluation. The estimates used long term metal prices of US$1.50/lb for copper and US$10.00/lb for molybdenum and a foreign exchange of C$0.80 per US dollar. Mr Thompson has reviewed this release. A technical report will be filed on www.sedar.com.
