The prospect El Cura is composed of quartz diorites, tonalites, granodiorites, granites, andesitic dikes, and aplitic dikes of the Pataz batholite. According to their composition of major and minor elements and trace element, they are Sub-alcaline, from sodic, sodic transitional to potassic types, from metalumine to peraluminic; of tectonic environment of volcanic arc, and sincolisionales, the depth to the magma source was 20 to 30 Km.The study area presents a structural compartment limited by river Huascacocha faults and the river Huiro Huiro fault both with dextral type; This area presents strong cracking, shear zones, crackle - breccia, where the vein and veinlets of polidireccional quartz are trapped, with extensive hydrothermal alteration, quartz - sericite and propilitic alteration; mineralizations of hematite, goethite, limonite, pyrite, gold, in veinlets and in fine dissemination, with low sulphide content such as galena, sphalerite, chalcopyrite, arsenopyrite, pyrrhotite and covelin.
