The Kumysty deposit is a significant valley-type gold placer located within the Kumystinsky ore field of the Suzak District. Discovered in 1980, the deposit spans a variety of terrains, from dissected lowlands in its upper reaches to an expansive alluvial fan at its base. The geological structure is particularly complex because it involves two distinct systems: gold hosted within the modern floodplain and gold preserved within a "buried" mid-Pleistocene paleovalley. The primary source of this gold is the regional network of quartz-sulfide veins found in Riphean-age dolomites and granosyenites.
The placer is characterized by a wide range of sediment sizes, including a significant 15% boulder content. The gold is typically concentrated at the interface with the bedrock (plotik), which consists of a diverse suite of rocks including schists, limestones, and granodiorites. Physically, the gold appears as poorly rounded nuggets, plates, and flakes, ranging from fine to medium grain size. While the average grade is approximately 0.1 g/m³, the deposit contains high-grade pockets reaching up to 33.2 g/m³. The site was mothballed in 1989 with residual C1 category reserves of 386 kg of gold.
