Small-scale Au-(Co) deposit, located at the intersection of Jilin-Heilongjiang Variscian orogenic belt and the Jiamusi fault zone. The deposit consists of stratiform gold bodies hosted in banded iron formation (BIF) of the Proterozoic Dongfengshan Group, which occurs at the core of an anticline. Four mineral facies occur in the BIF: (1) a sulphide layer, (2) a carbonate layer, (3) a silicate layer, and (4) an oxide layer. Gold occurs mainly in the sulphide layers.
