Yamana Reports Northern Porphyry Copper Belt Drilling Results
SPOKANE, WASHINGTON--Yamana Resources Inc. announces that reconnaissance drilling on eight of its ten properties in the Northern Porphyry Copper Belt (NPCB) of Chile failed to find potentially economic mineralization (see map). However, two other properties, Inca and Elvira, continue to show exploration promise. The presence of disseminated sulfide copper in drill holes, hydrothermal alteration assemblages, and other positive geological factors, indicate discovery possibilities still exist on these two.
The reconnaissance program was two and one-half years in the making. Contractors employed a combination of state-of-the-art geophysical, geochemical and geological techniques to identify targets hidden beneath gravel-covered areas on Yamana's properties. Drilling took four months, involved 37 reverse-circulation drill holes for 9,488 meters, and examined all of Yamana's properties except Huasco and Ollague, both located in the north near the huge Collahuasi copper deposit.
Drill results show that the remote sensing targeting techniques used on Yamana's properties, particularly enzyme leach geochemical surveys and TEM (transient electromagnetic) and IP (induced polarization) geophysical surveys, generated a large number of false anomalies and were ineffective in identifying mineralization. Yamana now considers that systematic reconnaissance drilling within favorable geologic settings is still the best method to find porphyry copper deposits.
Yamana considers it has made worthwhile progress in identifying mineralization on the Inca and Elvira properties, which will be the focus of its continued NPCB program. Other drilled properties will be eliminated, lowering the total claimed area from 60,000 hectares to approximately 32,000 hectares.
At Inca, the land position has been expanded from 10,600 hectares to over 16,000 hectares covering a gravel plain within a bulls-eye largely surrounded by claims of Rio Algom, Codelco, Noranda and other major mining companies. This is a historical mining region characterized by widespread and diverse mineralization. Inca is located just south of the Salvador and Potrerillos mines (see map) and close to the West Fissure Fault System, which controls emplacement of the giant porphyry copper deposits.
Of the five holes drilled at Inca, three encountered geochemically anomalous copper and zinc mineralization, together with extensive hydrothermal alteration, primarily of the argillic phase. Values up to 4,700 ppm Cu were encountered over 2 meters within longer sections of 200 to 400 ppm Cu. These holes are located 5 to 8 kilometers apart on opposite edges of an oval-shaped gravel basin. The mineralization is believed to be related to two major shear zones that intersect beneath the gravel plain, thus defining a priority site for a next phase of drilling.
At Elvira, drilling encountered trace amounts of copper within a zone of disseminated pyrite. The sulfides are associated with a large magnetic anomaly cross-cutting the West Fissure Fault Zone, a geologic aberration that warrants further investigation for its mineral potential.
Yamana intends to continue prudent exploration in the NPCB, where rewards for persistence can be tremendous.
