VANCOUVER, May 9, 2012 /PRNewswire/ - Taseko Mines Limited (TSX: TKO; NYSE Amex: TGB) ("Taseko" or the "Company") reports the results for the three months ended March 31, 2012.

Highlights

• Revenues for the first quarter 2012 were $55.4 million from the sale of 12.8 million pounds of copper and 354 thousand pounds of molybdenum.
  
  
• Total production at Gibraltar (100%), for the quarter ended March 31, 2012 was 20.7 million pounds of copper and 438 thousand pounds of molybdenum.
  
  
• On a 100% basis, capital project spending for the first quarter totalled $55.3 million.
  
  
• On January 31, 2012, Taseko received approval from the TSX to initiate a normal course issuer bid to repurchase up to 5.1%, or 10 million common shares, of the Company's issued shares.
  
  
• On March 28, 2012, Taseko announced the Aley Niobium Project resource has been upgraded to a Measured and Indicated Resource. At a 0.2% Nb₂O₅ cut-off, the Measured and Indicated Resource is 286 million tonnes with an average grade of 0.37% Nb₂O₅ plus 144 million tonnes of Inferred Resource with an average grade of 0.32% Nb₂O₅.
  
  
• As of April 2012, detailed engineering for the GDP3 Project was more than 70% complete and a definitive construction estimate for the project was completed. The estimate confirmed that the project remains on budget. Major planned construction milestones were achieved during the winter, leaving the project well positioned to take advantage of the spring and summer months to progress the work and achieve mechanical completion by year end.

For the three months ended March 31, 2012, Taseko had gross profit of $17.1 million and adjusted net earnings of $1.3 million ($0.01 per share). This compares to gross profit of $25.2 million and adjusted net earnings of $8.0 million ($0.04 per share) for the three months ended March 31, 2011.

Russell Hallbauer, President and CEO of Taseko commented, "Earnings in the first quarter were impacted by reduced sales due to the delayed loading of a marine shipment. The approximate six million pounds of copper that was not shipped in the first quarter was shipped early in April and therefore will augment second quarter sales. Also negatively affecting earnings was a $15.5 million unrealized loss on derivatives as well as $4.3 million expensed in the first quarter for the development of our Aley Niobium and New Prosperity projects."

"As previously disclosed, first quarter production was lower than anticipated due to ore characteristics, severe winter weather, ground water incursion at the lower level benches and a five-day unplanned shutdown to repair a SAG mill motor. These challenges resulted in reduced mill throughput of approximately 750,000 tons, or four million pounds of copper production."

Mr. Hallbauer continued, "Following a thorough project review with our engineering firm, it was confirmed that the GDP3 project remains on time and on budget. Mechanical completion is expected in December and commissioning will start at that time."
