Cerro Colorado Chico prospect is located to the south of the Ancash region, it is characterized by the presence of brecciated siliceous bodies (POD quartz) with restricted halos of advanced argillic alteration silica-pyrophyllite-alunite and an extensive alteration silic-sericite-pyrite, breccias and bodies of hematite, hematitized horizons affecting volcanic-sedimentary rocks of the Casma Group, and distal quartz veins. For this research have been geological mapping at 1:5000 scale, ASTER image analysis, ICP-AES analysis of 208 rock samples, petrographic, mineragraphic and XRD mineralogical analysis of 14 samples and fluid inclusion analysis of 4 samples. The altered rocks show an enrichment in Au, As, Sr, Ba, V, Fe, Ni and depletion of Cu, Pb, Zn, Al, Ti, Sc, Co and Mn. Petrographic studies show up to three generations of quartz and abundant hematite, sometimes replacing magnetite mold...
