The results of chemical analyses and the data on core samples for 266 drill holes were used to identify the geochemical zoning of the Peschanka porphyry–epithermal system. A 3D model of geochemical zoning was developed using factor analysis and GIS technologies to represent the spatial distribution of elemental associations and mineral assemblages. The lateral and longitudinal zoning patterns are described. The AgPbZn: CuAuMo ratio is suggested as an indicator of vertical zoning that allows to evaluate the erosion level of porphyry copper stockworks.
