The Las Antas Gold Project located within the prolific epithermal gold belt of Southern Peru is an important step towards development of a substantial land position in the region, generating multiple options with potential to provide high-grade feed to the Company’s Vista Gold plant.
The project, accessible by paved road to within 8km of the project, is 80km East of Peru’s prominent PanAmerican Highway and well within trucking distance of the Company’s Tulin and Vista gold processing facilities. The Project features an extensive zone of intense hydrothermal alteration at surface. The broader district contains multiple high-grade gold and silver veins located proximal to key prospects within the Las Antas project. The surface hydrothermal and breccia footprint is host to significant potential for larger scale, bulk tonnage, disseminated style gold mineralization.
Las Antas is hosted by the Calipuy volcanic layered stratigraphy in Southern Peru hosting andesitic flows, ignimbrites, tuffs, volcanic breccias and agglomerate units. The volcanic stratigraphy has been intruded by several andesitic to dacitic stocks, which comprise favourable units for mineralization and at surface are associated with a pervasive hydrothermal alteration system in halos of intense silicification, showing vuggy silica, alunite and illite
The project is located within the Oligocene-Pliocene gold-silver Belt of Southern Perú, which contains various precious metal deposits including the Ares Mine (1.2Moz Au & 15Moz Ag) and the Antapite Mine (600koz Au).
The Las Antas project has received early stage modern exploration techniques, with non-systematic geophysical coverage completed in historical exploration activity from 1995 through 1998 under a joint venture between Hochschild and Anaconda. The project area has seen only limited shallow reconnaissance RC drilling before exploration abruptly ceased in 1998.
Specific to the Las Antas Project area is two prioritized targets areas:
- Yuracmarca Target, 1.5×2.2 km of area with propylitization, argilization and silicification alterations.
- Cerro Amarillo Target, 3.5×2.3 km of area with intense silicification, in parts vuggy silica, altered breccias, alunite and Illite, argilitization and propylitization
