The paper presents the results of a study of heavy mineral concentrates of Kosumnerskoe gold deposit as well as the native gold from them. This gold deposit includes two gravel deposits. The granulometric composition, morphology, roundness, flatness, presence of intergrowths of gold with other minerals, as well as the character of the surface, the chemical composition and internal structure of gold, have been investigated. Based on these results, the placer gold of rivers Narta-Yu and
