OKTYABRSKY GOLD PLACER CENTER OF THE AMUR GOLD-BEARING PROVINCE, AMUR REGION, RUSSIA

Geological and structural features and gold potential of the Oktyabrsky Gold Placer Center, the Amur Gold Province, are described. The center consists of an ensemble of six ore and placer clusteres: Oktyabrsky, Yasnensky, Adamikhinsky, Sokhatino, Nizhnegarsky, and Nizhneselemdzhinsky. About 130 tons of gold have been produced in the placers of the center since the middle of the last century. The prospects for further development of placers are determined. They consist in the introduction of new technologies, which ensure the extraction of fine gold fractions and thereby involve the development of poor and technogenic placers. It is shown that the future of the Oktyabrsky Gold Placer Center depends on the discovery and development of new gold deposits of gold-quartz, gold-sulfide-quartz, skarn and gold-mercury (Karlin type) formations.
