Uchucchacua Mine, Oyon Province, Lima Department, Peru

Latitude & Longitude (WGS84): 10° 37' 23'' South , 76° 41' 17'' West

Uchucchacua mine is very close to the Raura mine in Cajatambo province, leading to label confusion.

Complex vein mineralization related to a dacitic intrusion cutting through Cretaceous and Tertiary formations on West side of Occidental Cordillera of Central Andes.

Mine Type/Method: Cut and fill[1] serviced by 2 vertical shafts exceeding 1.0 km depth, and a 4.6 km drainage tunnel.

Geology: A hydrothermal epigenetic deposit of landfill fractures, which were also transportation channels and metasomatic emplacements of mineralization that finally formed the present ore bodies. The principal commercial mineralization consists of silver, but zinc and lead are also extracted as by-products. Gangue minerals include calcite, kutnohorite, rhodochrosite, and quartz. Mineralization is located in limestones of the early Cretaceous.

Stress redistribution as a result of mining is responsible for the activation of a complex structural system of faults resulting in rockbursts at mine depths over 1 km (as of 2008).
