$NAK Over 20 years of mining, the Pebble Project as proposed will extract ~70 million tons of mineralized material annually at the extremely low strip ratio of just 0.12:1. A conventional blast-haul-crush and froth flotation milling process with nameplate capacity of 180,000 tons per day will be employed to produce, on average, 613,000 tons of copper-gold concentrate each year (containing 318 million lb Cu, 362,000 oz Au and 1.8 million oz Ag) and 15,000 tons of molybdenum concentrate (containing 14 million lb Mo).
