A copper mine with Phelps Dodge being the major shareholder. The mine consists of two large open pits, the Cerro Verde pit and the Santa Rosa pit, located at 2,700 m elevation, 34 km south of Arequipa city, from which its 480 employees are bused to work.
Ore is disseminated in igneous intrusion ("porphyry copper") and averages 0.52% Cu, currently working oxidized ore, but preparing to switch to primary sulphide-bearing ore. Mine moves 190,000 tons of rock per day, which is treated by one of the world's most modern heap leaching (hydrometallurgical) plants. Production in 2001 was almost 170 million lb Cu. (NB: This type of large-scale modern mining rarely results in any specimen-grade material being saved.)

|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.
