Abstract
In the Amur gold-bearing province, three placer gold mining centers have been identified – Solovyevsky, Oktyabrsky and Kharginsky, from whose placers, since the XIX century, a significant part (more than 80 %) of the province’s gold has been extracted. Each center consists of several converging ore-placer nodes, confined to the central nuclear part of the province. The centers differ in the typomorphic features of native gold, the composition of minerals associated with gold, and the sources of placer formation. It is shown that despite the long-term operation of placers for more than 150 years and their depletion, the level of gold mining has been steadily maintained in recent years at the level of 7–9 tons per year.
