Russian exploration to date (1968 to 1992) has defined a gold-mineralized system of quartz veins and linear silicified breccias in Triassic sandstones, shales and siltstones intruded by a granitoid dome and a late Cretaceous complex of independent small intrusions forming a ring dike structure. Early work in the area concentrated on tungsten mineralization in the contact metamorphosed sediments adjacent to the intrusives. Subsequent work focused on the gold mineralization, with a number of trenches and core holes being completed. Mineralogy of the mineralized bodies is simple. The main ore minerals are pyrite and arsenopyrite. Other sulfides present include antimonite.
