The new gold deposit in the Lower Amur region: Chulbatkan, Khabarovsk region

Abstract

The main characteristics of the Chulbatkan gold deposit are considered. This deposit consists of steeply dipping plate- and lens-shaped bodies with dessimination-veinlet mineralization in Late Cretaceous plagiogranites (Lower Amur complex) controlled by the NE- and NW-trending faults. The host rocks are affected by hydrothermal and metasomatic processes (beresitization, silicification, and carbonation). The only useful component in low-grade sulfide and non-rush ore is gold, while the silver content is insignificant. The resource potential of the deposit is estimated at 50 tons.
