The article addresses to the main characteristics of Chulbatkan gold deposit. The deposit is a steeply dipping of bed and lenticular ore bodies with dessimination-veinlet mineralization in the late Cretaceous plagiogranites (Lower Amur complex), controlled by the NE and the NW faults. The host rock mineralization exposed hydrothermal and metasomatic processes (beresitization, silicification and carbonation). The only useful component of the low-graded and non-refractory ore is gold; silver grade is low. Resource potential of the deposit estimated as 50 tons.
