Catalyst Copper Advises of PEA Filing Delay

Trading Symbol: CCY

VANCOUVER, Aug. 10, 2012 /CNW/ - Catalyst Copper Corp. ("Catalyst" or "the Company") advises there will be a delay in releasing the results of and filing the Preliminary Economic Assessment (PEA) on the La Verde copper porphyry deposit located in Michoacán State, Mexico.

The delay has been recommended after our consultants and ourselves reviewed all pertinent information. This review has determined that the existing geological model did not adequately report deleterious elements and as a consequence the economic model may be under-reporting the effect of these elements on net smelter return calculations.  While the data is available to correct the geologic model, the qualified person who prepared the report is no longer employed by the consulting firm that prepared the report.

The Company has retained Tetra Tech Inc. to prepare an updated geologic model and NI 43-101 report based on all work completed to date.  The Company has therefore elected to delay the release of the PEA until such time as the updated resource model can be incorporated.

We thank shareholders for their support and understanding.

About La Verde

La Verde is located in an area with excellent infrastructure. Power, rail and water all cross the property. Lazaro Cardenas, Mexico's third largest port on the Pacific Ocean coast is 180 km from the site. Significant upside potential remains for the two known zones of porphyry style copper, gold and molybdenum mineralization as the 2010 drill program has shown both deposits remain open to depth and along strike.

La Verde property is subject to an option agreement with a Mexican subsidiary of Teck Resources Limited (Teck) whereby Catalyst's 100% Mexican subsidiary, Minera Hill 29, may earn a 60% interest in La Verde by making US$10,000,000 in exploration expenditures (including 30,000 meters of drilling and 200 kilometers of IP) by December 31, 2012. Upon Catalyst earning a 60% interest, Teck has the option to increase its interest to 60% by incurring aggregate expenditures equal to two times the amount spent by Catalyst. Should Teck fail to exercise its option to earn a 60% interest, Catalyst can acquire a 100% interest in La Verde by paying to Teck US$20 million. The property is subject to an underlying 0.5% NSR.
