Reference information

Comments Active exploration; two permit areas are noted in a 2010 Lora Exploration investor presentation. Danbolongwa Permit area  (used as the location for Huangnan) is located in a region of As anomalies and is close to a Late Triassic diorite unit. Duoba-Jijiemu Permit area includes Yanshanian age granodiorite units, indicating that Huangnan might be younger (Jurassic-Cretaceous), thus included as part of the Porphyry copper assessment of the Mesozoic of East Asia (Ludington and others, 2012).
Study area name Central Asian Orogenic Belt
