VANCOUVER, Aug. 5 /PRNewswire-FirstCall/ - Catalyst Copper Corp. (the "Company" or "Catalyst") is pleased to announce the contracting of Micon International Ltd. ("Micon") to complete a NI 43-101 compliant resource estimate for the La Verde copper-gold porphyry project located in Michoacan State, Mexico which Catalyst's holds under option from a subsidiary of Teck Resources Limited. This resource estimate will incorporate all previously completed drill holes as well as drill data from the current drill program in progress.

Several historic mineral resource estimates have been generated at La Verde, but are not compliant with current CIMM and NI 43-101 guidelines. The last publicly released historic mineral resource of 72.6 million tonnes at an average grade of 0.7% copper was included in the 1972 feasibility study completed on behalf of Lytton Minerals Ltd. and was calculated prior to the enactment of NI 43-101.

Currently Catalyst has completed 4967 meters in 10 drill holes of the planned 10,000 meter program. Phase 1 of this drill program was designed to twin a number of the 1970's drill holes in order to verify historical grades and Phase 2 targeted extensions of known Cu-Au mineralized drill intersections.

All current drill holes have encountered visual copper mineralization as reported in the historical drill holes. To date, all completed holes drilled to twin historic holes have been extended past the original depth on the basis of the presence of visible copper mineralization (Table 1). Assay results are pending. Core samples are being sent to Acme Labs of Vancouver for analysis.

The Induced Polarization (IP) survey (geophysical program) is continuing with 100.6 line kilometres completed to date and 35 kilometres remaining to be completed. Areas which have returned interesting IP responses are being filled in with closer spaced lines where warranted. In particular, the process of investigating a magnetic signature in the southern part of the property led to the discovery of anomalous IP responses on 3 lines, 450 metres apart and still open along strike. This is regarded as very encouraging as previous geological and geophysical programs at La Verde demonstrated a strong association between anomalous IP responses and porphyry copper mineralization. Additional lines have now been laid out in this area to provide more detailed coverage.
