Historical data highlights a series of small pits and underground mines with gold production since the time of the Incas civilization. The project includes surface mapping, drillholes and surface and underground samples from different companies (drilled by: owners, Meridian Gold, Even Resources, among others), with interesting economic gold mineralization intersected by drillholes. Easy access to underground mineral resources in Diamante and Bienvenida claims, through a mining ramp up to 80 m depth, with a tunnel section of 4 m x 4 m.
In the El Inca area it is possible to observe volcanics and clastic rocks (middle to upper jurassic); Also there are present dioritic and granodioritic porphyries of tertiary age (paleocene). Intersecting volcanic-guest rocks, there is a dilatational jog system, which generates a mineralized zone or block, constituted internally by vein system and dissemination between veins with stockwork, with gold grade variation between 0.5 and 2 g / t Au. Many banded veinlets type crustiform are observed. Its mineralization corresponds mainly to gold, less silver, and less amount of copper. The Copper increases to the NE and gold and silver increase to SW. The veins are structures with width between 0.5 m and> 5 m. The main veins from south to north are Veta Cuatro Amigos, Veta Unión, Veta Inca and Veta Porteña. The gold grades of the veins are variable from 1 to> 25 g / t Au.
