Taseko Announces 2012 First Quarter Production and Sales Results

VANCOUVER, April 11, 2012 /PRNewswire/ - Taseko (TSX: TKO) (NYSE Amex: TGB) (the "Company") announces 2012 first quarter total production of 20.8 million pounds of copper and 438,000 pounds of molybdenum for its 75% owned Gibraltar Mine.

For the first quarter, Taseko's 75% share of sales was 12.7 million pounds of copper and 354,000 pounds of molybdenum.

In the first quarter, mill throughput was reduced by approximately 500,000 tons, equivalent to roughly 2.7 million pounds of copper production, due to processing ore from a harder than average portion of the Granite Pit, complicated by extended periods of -30° Celsius weather as well as ground water encountered at the lower level benches. Also, a five-day unplanned shutdown to repair a SAG mill motor resulted in a further reduction in mill throughput of 250,000 tons, or nearly 1.4 million pounds of copper production.

Quarterly Comparison

Copper inventory increased to approximately 6.8 million pounds at the end of the first quarter due to both port congestion and a mechanical breakdown at the vessel loading terminal which delayed Gibraltar's late March marine shipment to early April.

Russell Hallbauer, President and CEO of Taseko, commented, "We anticipate returning to more normalized concentrator throughput levels this quarter. Molybdenum recovery continues to improve quarter-over-quarter and we expect copper recoveries to stabilize at approximately 89%."

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