VANCOUVER, Feb. 1 /PRNewswire/ - Catalyst Copper Corp. (Catalyst or the Company) announced today that it has filed on SEDAR a NI 43-101 compliant report entitled "Technical Report on the Mineral Resources of the La Verde Property, Michoacán State, Mexico, January 19, 2011". The report was prepared by D. Makepeace, P.Eng., senior geologist for Micon Engineering International Ltd. (Micon) who is an independent qualified person as defined by NI 43-101.

Total Measured, Indicated and Inferred Resources determined for La Verde are listed below.

Measured, Indicated and Inferred Resources

Total East Hill plus West Hill

1. It cannot be assumed that all or any part of an Inferred Mineral Resource will be upgraded to an Indicated or Measured Resource as a result of continued exploration.
2. Mineral Resources are not Mineral Reserves because there are insufficient studies to demonstrate economic viability.
3. The Mineral Resource is a global in-situ total without constraints to an economic pit.
4. Mineral Resource numbers have been rounded and may not add up in the above table

The above numbers correct an error found in the compositing routine associated with the software Micon used to construct the resource model. At the 0.2% Cu cut-off the Resources published in the January 21, 2011 Catalyst press release were Measured plus Indicated of 210.5M tonnes at 0.46% Cu and Inferred of 130.8M tonnes at 0.45% Cu.

The 2011 drill program at La Verde has commenced with the first drill hole collared on January 29.

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.

The report was prepared by D. Makepeace, P.Eng., senior geologist for Micon who is an independent qualified person as defined by NI 43-101.The Mineral Resource estimate was completed using a 3D computer model. The drill hole database was based on 616 drill holes which totalled 92,881 meters. A composite interval of 5 meters was used and constrained to geological rock types. A single block model (10 x 10 x 10 meters) was created to envelope both mineralized deposits. Block grades were interpolated using the inverse distance squared technique. The estimate did not employ a high grade copper cap. A density (specific gravity) of 2.70 g/cm³was used for the East Hill deposit (porphyry style mineralization) while the West Hill deposit (chalcopyrite vein style mineralization) used 2.75 g/cm³, based on historical density measurements. All QA/QC requirements have been followed including incorporating standards, blanks and duplicates into the assay procedures and independent check analyses by a second laboratory.

Catalyst Copper is a Vancouver-based publicly traded mine development company (TSX-V: CCY) that optioned the La Verde copper porphyry target from a subsidiary of Teck Resources Limited.
