Ranking the Productivity Potential of Ore-Placer Nodes of the Amur Gold-bearing Province

Abstract

Ore-placer nodes with a high, moderate, and low productivity were distinguished according to the level of gold mining in the Amur Province. It has been shown that highly and moderately productive oreplacer nodes are naturally attributed to metallogenic zones of the central part of the province, and low productive nodes, to the peripheral parts. This is due to the presence of large ore-leading faults in the central part of the province. The areas with highly productive ore-placer nodes are the most promising to explore ore gold; the areas with moderately and low productive ore-placer nodes are less and much less promising, respectively.
