  • Large land position located in San Juan Province, Argentina immediately adjacent to the Chilean border. Access to the area is via Calingasta, the nearest town, along 125km of unpaved road to the Los Azules Cu-Mo porphyry project (962Mt @ 0.48%Cu; McEwan Mining) and then north along a dirt road to the La Coipita project.
  • The project is located within the Miocene porphyry-epithermal belt of Chile and Argentina. La Coipita is along strike from numerous prolific deposits hosted within this belt such as Pelambres/Pachon (Antofagasta Minerals), Los Azules (McEwan Mining), El Indio (Barrick), Veladero (Barrick) and Pascua Lama (Barrick).
  • Previous work on the project by Viceroy (1995-1997), Vale (2007-2009) and Teck (2010-2016) included rock and soil (talus) sampling, geological mapping, geophysical surveys (IP and mag), trenching, spectral analysis (PIMA and Aster) and limited drilling (nine RC holes totalling 1,984m).
  • The 1997 drill program by Viceroy tested the HS epithermal Yareta target. Results included: 97-Y-3: 109m @ 0.42% Cu, including 41m @ 1.08%Cu, 0.35g/t Au and 24.2g/t Ag; 97-Y-5: 42m @ 0.60% Cu, 0.26g/t Au and 9.26g/t Ag; 97-Y-9: 37m @ 0.24% Cu; 97-Y-8: 10m @ 0.97% Cu, 0.12 g/t Au, 4.53 g/t Ag.
  • While the drilling targeted and intersected HS epithermal mineralization, two of the holes ended in alteration and mineralization interpreted by Vale and Teck as being consistent with a transition to a porphyry-type system. No further drilling has been conducted to test this theory.
  • Several other targets areas on the property are characterized by Aster and geophysical anomalies with outcropping alteration and/or mineralization consistent with a porphyry system.
