Taseko Updates Status Of Gibraltar Mine

July 8, 2008

July 8, 2008, Vancouver, BC - Taseko Mines Limited (TSX:TKO; AMEX:TGB) wishes to provide an update on its Gibraltar Mine. As announced on May 8, 2008 the main transformer for the new SAG mill failed resulting in a 16-day outage of the concentrator. An investigation into the failure of the transformer indicated that it had a defect when it was purchased, and it was this defect that was the root cause of the failure. Taseko is now pursuing warrantee coverage from the supplier as well as loss of business insurance.

During this unscheduled outage, maintenance personnel utilized the available time to work on further mill upgrades, chute repairs and areas affecting material flow that have been impacting concentrator performance.

The 3.3 million pounds of copper production lost in May, combined with higher than normal operating costs due to the accelerated maintenance activities referred to above, as well as a change out of the SAG mill liners after 6 months of operation will have a direct impact on Taseko’s third quarter financials.

Since January, the mill operation’s team has made steady progress towards integration of all the concentrator circuits from the primary crusher, the SAG mill and into the downstream secondary grinding and recovery systems as defined in the Phase I scope of work. The integration of these milling circuits has been more challenging than anticipated. While targeted operating levels for the SAG mill, ball mills and flotation system have been achieved on an individual basis, optimizing how each circuit works and interacts with the others is taking longer than planned.

The following table shows the average daily production rates that have been achieved over the past six months.

Average Production Rates
(pounds per day)
Annualized Production Rates
(millions of pounds)
January 103,400 37.7
February 114,900 41.9
March 177,900 64.9
April 144,900 52.9
May* 168,700 61.6
June** 178,800 65.3
* Exclusive of 16 day outage due to failure of transformer.
**Exclusive of three day outage to change SAG mill liner.

The Phase II expansion is continuing on time and budget with the cleaner cell installation complete and expected preliminary circuit operation commencing by the end of July.

Mine operations commissioned the first of two new production drills in June and are now preparing mining areas in anticipation of the arrival of the new 60 yard mining shovel. This is the first of the three new 60 yard mining shovels that are required to provide feed for the anticipated 85,000 ton per day concentrator capacity.

Russell Hallbauer, President and CEO of Taseko commented, “While uncontrollable events, such as the failure of the transformer are unfortunate and will affect our financial performance in the near-term, we remain focused on integrating and optimizing our new concentrator circuit and adding our Phase II upgrades as expeditiously as possible to coincide with the mining department’s ramp up in daily mining rates.

“We expect our increasing copper production trend to continue in the months ahead as we capitalize on ongoing circuit integration of both our Phase I & II expansion and modernization programs.

“With copper prices in the $3.90/lb range, our Phase I production levels nearly achieved and our Phase II construction program advancing as planned, we are making excellent progress in all areas of our business plan and are excited about the next step change we see coming in our operations.”
