La Providencia is an epythermal deposit of silver, copper, lead and zinc found in quaternary deposits (Deposits of La Providencia, Peralta and Sureda, 1992. Pleistocene), which all are superimposed by the tectonic shift of red bed-type sediments of the sediments group known as Pastos Grandes (Sijes Formation) of the Tertiary Period. Such sediments are based upon clay rocks and Ordovician greywackes of the Acoyte Formation.
This is a deposit of scattered metals whose concentration is higher in the fractures affecting the conglomerate. Such fractures are likely to conduct mineralizing fluids from a source whose location and geometrical disposition is still uncertain.
