A large modern open-pit copper-rhenium-molybdenum mine in copper porphyry, disseminated fine-grained sulphide ore with abundant anhydrite veins and tourmaline breccias.
Owned by SPCC. Reserves: 700 million tons @ 0.74% Cu. Crystal vugs are either rare or nonexistent. The oxide zone has been completely consumed. Located not far from the Moquegua department border.
28 valid minerals.
GeochronologyMineralization age: Paleocene : 57 Ma
Important note: This table is based only on rock and mineral ages recorded below and is not necessarily a complete representation of the geochronology, but does give an indication of possible mineralization events relevant to this locality. As more age information is added this table may expand in the future. A break in the table simply indicates a lack of data entered here, not necessarily a break in the geologic sequence. Grey background entries are from different, related, localities.
|Geologic Time||Rocks, Minerals and Events|
This geological map and associated information on rock units at or nearby to the coordinates given for this locality is based on relatively small scale geological maps provided by various national Geological Surveys. This does not necessarily represent the complete geology at this locality but it gives a background for the region in which it is found.

|Paleoproterozoic intrusive and metamorphic terranes|
Age: Proterozoic (1600 - 2500 Ma)
Comments: Mixtures of metamorphic and intrusive or plutonic rocks, tracts known as crystalline, migmatitic terranes, moderately to highly metamorphosed rocks of unknown origin with or without intrusions. This classification is inherently prone to variable interpretation, as other compilers might distinguish some packages by their metamorphic or gneissic protoliths, and the associated age ranges may be more variable.
Lithology: Intrusive and metamorphic terranes
