Gold-copper-polymetallic ore bodies, hosted in Triassic limestones and shale and Quartenary sediments around alkaline porphyries and Permian basalts. A porphyry-skarn deposit type. The third largest Au deposit in China with estimated 323 t of Au, by the 2.47 g/t concentration. The ore bodies are grouped in two ore zones, each of which comprises several mines (ore blocks): the Hongnitang, Jingouba and Wandongshan mines in the western ore zone, and the Bijiashan, Weiganpo and Wulipan mines in the eastern ore zone.
