Reference information

Comments Medium size deposit, small mining operations at the start of 20th century. Grades: 0.3–0.9% Cu, 0.001–0.006% Mo, up to 0.7 g/t Au; 0.15% Pb, 0.03% Bi. Exposed. Location: Akbiik; best guess from Google Earth (March 9, 2010) using geology as guide; faults discernible on satellite image; 18 km E of Singer and others' (2008) location. Singer and others (2008) use Almaly as collective name for two nearby deposits, Akbiik and Oginskoe; however, there is no evidence of exploration activity at their given location on Google Earth (March 8, 2010).
Study area name West Central Asia
