Potential of the Amur Region for ore gold

Information on the metallogeny of the Amur Province, the identification of metallogenic zones and ore-­placer clusters in it, placer and ore gold extraction since 1868 is given. The ore-­placer clusters were ranked as high­ (more than 50 tons mined), medium­ (10–50 tons) and low-­productive (less than 10 tons) according to the amount of gold mined. High-­productive ore­-placer clusters are subdivided into predominantly placer, ore­-placer and predominantly ore clusters. It is shown that high-­productive ore­-placer clusters have the highest potential in the exploration of new gold deposits; in them, primarily, ore clusters and then ore-­placer and placer clusters are most promising.
