Abstract

General information on geological structure and gold potential of Manitanyrdsky area located in the western Polar Urals is provided. Niyayuskaya ore zone is revealed, Verkhneniyayuskoye-2, Niyakhoiskoye-2 and Yagodnoye mineral occurrences are characterized. It is shown that, aside from vein gold-sulfide-quartz mineralization, disseminated and veinlet-disseminated mineralization separated from quartz veins is widespread, which is also of economic interest. Gold in ores occurs as ultrafine inclusions in arsenopyrite and pyrite; it is also found in cross fractures as overgrown with later sulfides, which suggests two ore formation stages – gold-pyrite-arsenopyrite and gold-chalcopyritesphalerite- galena. Lithochemical prospecting results are presented, gold-enriched areas are identified. Prospects for the area’s resource potential ramp-up are assessed.
