The Haiyu Gold Mine is the first seabed gold mine discovered in China. It is situated in the Sanshan Island-Cangshang Fracture Zone, a highly prospective metallogenic belt on the Jiaodong Peninsula along the Bohai Bay. The zone is renowned globally for extensive gold mining activity and is one of the most important gold production bases in China. Thanks to good metallogenic conditions, a number of ultra-large and large gold mines have been discovered in the region. The Haiyu Gold Mine has a thick, large orebody. With the orebody open at depth, it enjoys significant potential for further increase in reserves.
