Reference information

Comments 0.1–0.3% Cu in 0.2 by 0.9 km bedrock area. Deposit extends along the external contact of granodiorite and granosyenite massif. This zone divided into 3 subzones. These subzones are parallel and each is about 50 m wide and extend for 1000 m in a nearly EW direction. One prospect from Nokleberg and others (1999) was grouped with this site; their location for ""Unnamed - Nokleberg (1999), [CAOB 1]"" is 44.2333 degrees N latitude and 108.05 degrees E longitude. Was an Ivanhoe target with anomalous Auchip samples in 2004.
Study area name Central Asian Orogenic Belt
