A 17-hole drill program by Minera Andes (MAI-A) has identified a copper porphyry prospect in the southern portion of La Horqueta, an exploration project in Argentina’s Mendoza province.
The drilling intersected sub-economic gold values. However, as work progressed southward, a systematic increase in disseminated copper values was noted in the direction of a large induced-polarization anomaly.
Minera Andes optioned mineral rights south of La Horqueta to ensure ownership of ground covering possible extensions of the copper porphyry target there.
The company controls some 35 projects covering 700,000 acres in Argentina.
Most of these are in the Andean Cordillera, with gold and copper being the primary exploration targets.
Drilling is under way at the Agua Blanca gold-copper prospect in San Juan province, near the eastern edge of the Chilean copper belt known as El Indio.
The project is a preliminary joint venture with Newcrest Resources of Australia.
Newcrest’s field work is reported to have defined three gold-copper mineralized targets that lie in a large envelope of alteration.
Drilling is scheduled to start in April at the Santa Clara porphyry copper prospect in Mendoza province. Joint-venture partner Cominco (CLT-T) will manage the 2,000-metre, reverse-circulation program. The primary target is the Quebrada del Azufre anomaly, part of a multiple porphyry target complex.
