The property lies on the western flank of the Peruvian Andes at an elevation of 4,000 to 4,260 meters above sea level.

It is an open-pit, crush, valley-fill heap leach operation.

A ~14 Moz high-sulfidation epithermal deposit that is hosted by an atypical host-rock succession for this deposit type. Approximately 80% of the ore body is contained in the Lower Cretaceous Chimu Formation, which is composed of quartz arenite with interbedded carbonaceous mudstone, siltstone, and coal seams. The remainder of the ore is hosted by the Miocene volcanic rocks of the Calipuy Group, forming an irregular and thin veneer on the deformed sedimentary rocks of the basement.
