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.
