On the basis of geological-petrographic and ore-geochemical researches it is distinguished four types of rocks: 1 – intrusive (gabbro, gabbro-norites, norites), 2 – sedimentary (manganous dolomite), 3 – metasomatic (magnesian skarns), 4 – ultrametamorphic (plagiomigmatites, micaites, quartz veins, postgabbroiccrystalloschists, pegmatitic granites). It is established gold-arsenic-sulfide (high-temperature) and gold-silver-sulfide (low-temperature) types of the mineralization, located in magnesian skarns.
