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.
37 valid minerals.
