This deposit is composed by 14 ore bodies with a clear alignment in a NW-SE. These ore bodies are configured in 4 principal trends along the volcanic basin.The mineralization is controlled by 2 faults system. A NW-SE extensional system which generated the basin configuration and presented several reactivations during the mineralization emplacement, and N-S system as feeders of the Zn, Cu, Pb and Ag mineralization. A post mineralization intrusion of porphiritic andesitic dikes with an orientation NNE-SSW that cross-cut all the mineralization. Additional to these systems there are NE structures associated to ore remobilization at the Eastern of the deposit that are considered as small ore bodies with high economical grades as new targets.
