Tanjianshan Gold Mine, located in Haixi Prefecture, Qinghai Province, has always been the focus of the industry. Since the mine signed a joint development contract with Australian China Mining Group Company (renamed Australian Gold Co., Ltd. after the equity reform in 2002), Australian Gold transferred all its shares to Canadian Afkan Mining Co., Ltd. in 2003. However, in September 2005, Afukan Company was merged by Canada's Elrado Gold Company, and the main body of Tanjianshan Gold Mine changed hands again.
