CUU own 25% Schaft Creek: proven/probable min. reserves/940.8m tonnes = 0.27% copper, 0.19 g/t gold, 0.018% moly and 1.72 g/t silver containing: 5.6b lbs copper, 5.8m ounces gold, 363.5m lbs moly and 51.7m ounces silver; (Recoverable CuEq 0.46%)
Until I'm able to better understand how they pulled such good production numbers in 2008 with 25% less tonnage and lower grades, I'll stick to this version for now which uses the 2013 numbers for the conversion.
