Lead-zinc mine.
Located 15 km NE of Cerro de Pasco.

Lead-zinc ores occur mainly as irregular replacement bodies and veins in Jurassic limestone and as galena-rich veins in Cretaceous sandstone. Mineralization is also found along contacts and in small fractures in Tertiary dacite which was emplaced following the main period of folding and strong faulting in the district.
