Exploration and mining of uranium ore was carried out in 1904. Since olden times local people mined copper here. Commercial mining of radium ore was organized in 1922. Reserves of deposit estimated 15-20 grams of radium, 60 tons of uranium, 120 tons of copper. The initial performance of the mine was 500 tons of ore per year. Mining of the deposit was carried out by underground methods and has been discontinued due to the abundance of underground water at a depth of 220 meters.

During the raid specialists conducted a visual survey and measurements of gamma-ray background in the territory of radium mine. As a result of the survey it was found that the mine Too-Moyun is located at the junction of administrative territories of Nookat and Aravan regions of Osh oblast, on the lands of Kara-Tash rural districts.
