Regularities of gold localization conditions in the brown coal deposits of the Upper and Middle Priamur Region are investigated. It is established that gold placer and coal-bearing structures are often conjugated to each other forming a single complex that indicates their age paragenesis. It is proved that gold release and localization during the Cenozoic within the region under consideration occurred in the systems of inherited paleovalleys. Organic matter in these paleovalleys served as geochemical barriers with the formation of complex compounds not dissolved in water. It is established that gold and silver occurred in coals in the native state with the formation of separate phases and predominance of silver grains. Noble metals as well as most other ore minerals in brown coals are characterized by a corpuscle-spongy structure.
