Reference information

Comments Reserve (mostly skarn): 29 Mt at 0.44% Cu and 0.024% Mo. Reserves also calculated for Ag, Se, Te, Re, In, and Co. Exposed. Location: location is open pit on mine on Google Earth (March 11, 2010) interpreted to be Karatas I based on Khotov and others(1998); according to Khotov and others (1998), the Karatas I, II, III, and IV are within a 4 square km area, a very different distribution than implied by locations included in Seltmann and others (2009).
