Pyrite deposits hosting relatively high-grade gold ores are presented as a group of gold-rich pyrite deposits. Some of their features were studied for Saumskoye and Galkinskoye deposits. Exploration data on these deposits resulted from advanced estimates made by JSC Polymetal mining companies. Works at both deposits included 3-D tracing of spatial localization for ore-level Au, Cu and Zn concentrations (Au≥1 g/t, Сu ≥1%, Zn ≥1%), geochemical and technological differences in gold-rich and gold-free pyrite ores are defined, chemical element oxidation trends are noted. The paper may be of interest to geologists engaged in prospecting for primary gold and its estimation in areas hosting gold-rich pyrite deposits, and technologists who develop technological regulations of ore supply to a
processing plant from such deposits.
