Minasccassa
The Minasccasa property is located in the Andahuaylas – Yauri metallogenic belt in southern Peru, 400 kilometres southeast of Lima. Road access from Lima is through Ayacucho, a distance of 575 kilometres and a travel time of eight hours. Minascassa is comprised of three exploration concessions totalling 2,500 hectares and is 100% owned by Collasuyo.
A program of regional stream sediment and outcrop sampling and geological mapping conducted in 2000-2001 by the Bambas West Joint Venture (Southwestern – Inco Limited), resulted in the discovery of a mineralized zinc-copper skarn system at Minascassa. The skarn is developed in Permian limestone of the Copacabana Group, which is intruded by tertiary monzonite porphyry dykes and apophyses. The productive monzonite has intruded along the contact between older Permian granite of the Querobamba batholith and contact metamorphosed country rocks.
Mapping and sampling to date has shown that the skarn system is very extensive, with garnet skarn hosting zinc-copper mineralization over a strike length of 1,200 metres and a vertical extent of 600 metres. Numerous mine workings, mostly caved and flooded, were worked at a small scale on high-grade zones of mineralization in two areas. Mineralization is widespread and in places is significantly leached and oxidized at surface, with scattered exposures of higher-grade material (in excess of 9% zinc). Further evaluation with trenching, geophysics and diamond drilling is warranted.
