Although the surrounding terrain has been staked by other interests, and although similar Tertiary volcanic centers have hosted major precious metal deposits in the Cordillera Occidental of Peru, the only known mineral deposit of importance in the immediate vicinity is the Cerro Lindo Mine, a volcanic massive sulfide deposit unrelated to the
Pucamayo mineralization.

In the regional setting, Lower Cretaceous sediments are overlain by island arc andesites, which host the nearby Cerro Lindo volcanic massive sulfide deposit. These have been invaded by an intrusive complex known as the coastal batholith, with both Cretaceous and Tertiary units. Overlying these are Pliocene-Pleistocene tuffs and flows of acid composition related to a nearby volcanic center.

This is part of a Tertiary volcanic belt which hosts major gold-silver deposits in Peru, such as Yanachocha, Pierina and Alto Chicama. In the vicinity of the property, rhyodacitic tuffs overly both pre-mineralization andesites and granitic rocks.

The precious metals are hosted in epithermal systems related to this relatively recent phase of volcanism. The deposits are controlled both by northwest trending fractures (which dominate the Cordillera) and by northeast trending cross-fractures. It is likely that the interaction of these two systems produced sites of dilation, which assisted emplacement of epithermal materials.

Its operations began in July 2007, producing concentrates of zinc, copper and lead, with contents of silver, through a mineral flotation process in the concentrator plant.

At the beginning of its operations, the concentrator plant had a capacity 5,000 tpd treatment; however, between 2011 and 2014 three expansion projects were developed, the latter of which made it possible to reach a treatment capacity 18,000 tpd by the end of 2014 and to stabilize it, steadily at that level during 2015.
