This publication is part of the project: “Study of Mesozoic magmatism and its implications in the determination of a geological-structural exploration model related to the occurrence of IOCG type deposits in the Cordillera de la Costa and pre-Andean plains of the Peruvian Andes” by means of the framework agreement between UNMSM and INGEMMET. The location of the prospective areas was using Landsat 8 images, choosing Cerro Colorado Chico for its accessibility. The geomorphology stands out for showing outcrops of isolated hills with strong oxidation and hills. In the field stage, the geological cartography of 5 predefined zones and oriented sampling was performed. Intrusive rocks, altered porphyritic volcanic rocks, gaps, quartz veins, clays were observed. The mineralization observed was chalcopyrite, covelite, large amount of pyrite, hematite, goethite, jarosite, etc. The alteration ob...

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...
