The main purpose of Dalstroy as an organization was to obtain benefits for the state from little-known and little-explored territories of Northeast Siberia. Expeditions were financed by the USSR in order to explore the region as early as 1928. the First Kolyma Expedition in 1928 led by geologist Yuri Bilibin and the Second Kolyma Expedition in 1931-1932, organized by Bilibin and led by Valentin Tsaregradsky resulted in the discovery of gold deposits in Northeast Siberia. From then onward, emphasis was laid in ambitious mining operations to obtain the maximum amount of gold and other strategically important minerals.
