Summary:
Caserones is a copper-molybdenum porphyry deposit geographically located in the high-cordillera of the Chilean Andes at the southern end of the Maricunga mineral belt. Caserones is an EarlyMiocene porphyry system associated with a cluster of dacite porphyries and breccias intruding Palaeozoic granitic, volcanic, and metamorphic rocks, and has a well-developed supergene enrichment profile of oxide copper and secondary chalcocite situated above hypogene chalcopyrite mineralization.
The Regalito Deposit strikes SE-NW with a length of approximately 2,000 m and a width of approximately 1,500 m. The oxide and secondary copper zones form a surface-parallel blanket over 1,200 m in diameter, with a central “core” of at least 1,000 m in diameter where thicknesses average 300 m and exceed 400 m in the central part. Secondary copper grades within this central area are also slightly elevated above those in the surrounding parts of the deposit. Outboard of this “core” the zone thins, and grades are generally lower, although the enrichment blanket is still open to the southwest. The secondary copper zone has been modeled to approximately 4,000 m in elevation and deeper locally. It is generally coincident with the porphyry intrusive.
The oxide zone forms a cap that sits on top of the secondary copper zone in the upper part of the northeast trending ridge that constitutes the northwest margin of the deposit, mostly above 4,400 m, and thinning to a skin of a few metres mo ........

Summary:
The Caserones open pit mine is developed upon a significant porphyry copper-molybdenum deposit in the Atacama Region of the northern Chilean Andean Cordillera, 162 kilometers southeast of the city of Copiapó, at an approximate elevation of 4,300 meters above sea level.
