Caserones is located at the southern end of the well documented Maricunga mineral belt and comprises an Early-Miocene porphyry system associated with a cluster of dacite porphyries and breccias intruding Palaeozoic granitic, volcanic, and metamorphic rocks. Caserones has a well-developed supergene enrichment profile of oxide copper and secondary chalcocite that overlies hypogene sulfide (chalcopyritemolybdenite) mineralization.

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.

Caserones considers an open pit operation, with a plant to produce copper and molybdenum concentrates from primary sulphides; and a solvent extraction and electro-obtaining plant (SX-EW) to produce copper cathodes by processing oxidized, mixed minerals and secondary sulphides.

Production of copper and molybdenum concentrates process:
Crushing / grinding -> flotation / dewatering / draining -> copper concentrate and molybdenum concentrate.

Production of refined copper:
Dump-leaching -> SX-EW -> Refined copper.
