Vancouver, BC - Taseko Mines Limited (TSX: TKO; NYSE Amex: TGB) (“Taseko” or the “Company”)reports unaudited second quarter production results for the Gibraltar Mine.

For the second quarter of 2011, Gibraltar produced 20.0 million pounds of copper and 300 thousand pounds of molybdenum.

A quarter over quarter production comparison is below:

Gibraltar’s SAG mill direct feed system was commissioned in early June, with ramp up ongoing over the last four weeks.

With metallurgical recovery performance stabilized at current throughput rates efforts are now concentrated on optimizing mill throughputs and incrementally increasing hourly and daily tonnage, working towards the design capacity of 55,000 tons per day.

Russell Hallbauer, President and CEO of Taseko, commented, “Operational improvements at Gibraltar continue as concentrator personnel work to increase daily mill throughput now that the SAG feed system is operational. As mill personnel become more experienced with operating at the higher throughput rate we anticipate re-establishing copper recovery approaching 90%.

We will progressively up mill throughput as we are better able to deal with the larger SAG mill feed. The increase in throughput will be dependent on optimizing recirculating load, ball charge, SAG mill grate discharge sizes, and power draw on the mill motors. Each one of these operational parameters is critical to achieving targeted mill throughput and requires processes and procedures to realize maximum results, which we expect to accomplish by year end.”

Mr. Hallbauer continued, “In addition, site prep has begun for Gibraltar Development Plan 3 (GDP3), with all major milling and mining equipment secured and engineering well advanced. Once complete Gibraltar’s annual production capacity will increase to 180 million pounds of copper and 3 million pounds of molybdenum.”

Note: Gibraltar is a Joint Venture owned by Taseko Mines Limited (75%) and Cariboo Copper Corp. (25%). All figures are reported on a 100% basis.

• uncertainties related to feasibility studies that provide estimates of expected or anticipated costs, expenditures and economic returns from a mining project;
• uncertainties related to our ability to complete the mill upgrade on time estimated and at the scheduled cost;
• uncertainties related to the ability to obtain necessary licenses permits for development projects and project delays due to third party opposition;
• uncertainties related to unexpected or ongoing judicial or regulatory proceedings;
• changes in, and the effects of, the laws, regulations and government policies affecting our exploration and development activities and mining operations, particularly laws, regulations and policies;
• changes in general economic conditions, the financial markets and in the demand and market price for copper, gold and other minerals and commodities, such as diesel fuel, steel, concrete, electricity and other forms of energy, mining equipment, and fluctuations in exchange rates, particularly with respect to the value of the U.S. dollar and Canadian dollar, and the continued availability of capital and financing;
• the effects of forward selling instruments to protect against fluctuations in copper prices and exchange rate movements and the risks of counterparty defaults, and mark to market risk;
• the risk of inadequate insurance or inability to obtain insurance to cover mining risks;
• the risk of loss of key employees; the risk of changes in accounting policies and methods we use to report our financial condition, including uncertainties associated with critical accounting assumptions and estimates;
• environmental issues and liabilities associated with mining including processing and stock piling ore; and
