Trading Symbol: CCY VANCOUVER, July 11, 2012 /CNW/ - Catalyst Copper Corp. (the "Company" or "Catalyst") advised that an initial draft of the Preliminary Economic Assessment (PEA) on the La Verde copper porphyry deposit located in Michoacan State, Mexico initiated in early May 2012 by AMC Mining Consultants Ltd. ("AMC") of Vancouver was delivered to management at the end of June. Management and its financial advisors, Endeavour Financial Limited (of both Vancouver and London), have now completed their review and provided comments to AMC. Subject to final review, it is expected that report will be publicly released later this month. About La Verde La Verde is located in Michoacan state, Mexico, in an area with excellent infrastructure. Power, rail and water all cross the property. Lazaro Cardenas, Mexico's third largest port on the coast of the Pacific Ocean is 180 km from the site. Significant upside potential remains for the two known zones of porphyry type copper, gold and molybdenum mineralization as the 2010 drill program has shown both deposits remain open to depth and along strike. The Company's interest in La Verde property is held under an option agreement with a Mexican subsidiary of Teck Resources Limited (Teck) whereby Catalyst's 100% owned 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 has the right, but not the obligation, to acquire a 100% interest in La Verde by paying to Teck US$20 million. The property is subject to an underlying 0.5% NSR. ON BEHALF OF THE BOARD OF DIRECTORS OF CATALYST COPPER CORP. "John W.
