Reference information

Comments Grade and tonnage data from Tang, Wang, Wyman and others (2010). Discovered in 1985-90; drilled out in 2002-2008 with 62 drill holes. Hydrothermal alteration (potassic, phyllic, propylitic) is associated with both the main phase diorites and late diorite porphyry.
Study area name Central Asian Orogenic Belt
