Providencia

La Providencia is an epitermal deposit of Silver, lead, copper and zinc lodged in conglomerate sediments of quaternary (Conglomerate La Providencia, Peralta and Sureda, 1992. Pleistocene), which overlie tectonic contact with red sediments of Pastos Grandes group (Sijes Formation) of the Upper Tertiary. The latter rely on unconformity on the Ordovician pelites and wackes of the Acoite formation. It is a deposit of metals scattered in sediments, where there is a greater concentration of them in the fractures that affect the conglomerate.

Production from the reprocessing -2,000 tpd- of mineral tails from previous exploitations to extract the materials that are still preserved.
