Projects Sierra de las Minas Project
The Sierra de las Minas is a northerly trending belt of Precambrian to Paleozoic metamorphic and intrusive rocks located in La Rioja Province, central Argentina. The district is well mineralized with numerous small mines, prospects and showings. The majority are discontinuous, lenticular gold/polymetallic veins in tensional brittle fracture systems, as exemplified by Las Callanas, which cross cut the pervasive regional foliation in the granite-gneiss rocks of the area. The potential exists for small tonnage mesothermal bonanza grade, gold mineralized bodies, in these vein systems. A second style of gold mineralization is represented by the brittle-ductile shear zone hosted gold mineralization found at El Abra, which offers a significantly larger size potential in veins and disseminations with continuity of good grades, and is thus a more suitable target for the company at this time. The brittle-ductile shear zone style of mineralization is spatially related to the Ulapes structure, a north trending regional structure, particularly in sectors where there are cross structures and/or flextures in the pervasive ductile tectonic fabric, and localized to the eastern half of the property holdings. Areas in the northeastern and southern portion of the Sierra where the Ulapes Structure is cut by northwest trending bands of anomalously non-magnetic rocks appear particularly promising. The Company's current holdings are approximately 6,000 hectares in area and cover areas of known gold mineralization or inferred extensions of brittle-ductile shear zones in the eastern part of the Sierra de Las Minas.
