La Providencia is an epithermal 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. These fractures were possibly the means of transport of the mineralizing fluids from a source whose location and geometric arrangement is still uncertain.
