Latitude & Longitude (WGS84): 8° 0' 39'' South , 78° 19' 18'' West
Latitude & Longitude (decimal): -8.01111,-78.32194
Köppen climate type:BSk : Cold semi-arid (steppe) climate

A Cu-Pb-Zn-Ag-Au mine owned by ASARCO (80%). 1984 production was 358,000 tons/ore (2,400 tons Cu; 3,500 tons Pb; 10,000 tons Zn; 55,200 kg Ag & 78 kg Au).

Known for excellent specimens of orpiment, enargite, hutchinsonite, and pyrite.

Mesothermal and epithermal Cu-Pb-Zn ore mineralisations in an area of andesitic and basaltic volcanics. Four distinct zones can be recognized. From the center, they are the enargite zone, a transition zone, the Pb-​Zn and the stibnite zone. Alteration includes chloritization, propylitization, argillization, and silicification.
