33 XIV CONGRESO INTERNACIONAL DE PROSPECTORES Y EXPLORADORES DESCUBRIENDO RECURSOS MINERALES PARA UN MUNDO MEJOR REVISE PAPER This study seeks to enrich our understanding of highsulfidation (HS) ore-forming processes in siliciclastic environments and guide exploration in siliciclastic terranes by studying the La Virgen district in northern Peru, 17 km east of the giant Lagunas Norte HS deposit, in which the HS mineralization is mostly hosted in the sandstone of the Chimu Formation and other siliciclastic rocks. In addition, this is the first detailed study of La Virgen District and has led to the discovery of porphyry style mineralization in the eastern part of the area, which, based on mapping, geochronology, SWIR (Short Wavelength Infra-Red) spectral analysis, petrography, LA-ICP-MS and whole rock geochemistry, is shown to have significantly older mineralization than the western side.
