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 Nester-Shor has been concluded to be similar in morphology, chemical composition and internal structure so it allows attributing them to a single type of motherload, which could be named as gold-polysulfide-quartz type. On the results of the analysis of two gold deposits of this field, the gravel deposit of the river Nester-Shor has been concluded to be elder than gravel deposit of the river Narta-Yu.
