Indonesia's third-quarter 2012 copper sales of 195 million pounds and gold sales of 178 thousand ounces were lower than third-quarter 2011 copper sales of 253 million pounds and gold sales of 384 thousand ounces, primarily reflecting anticipated lower ore grades. Third-quarter 2012 sales volumes for copper were similar to the July estimates, but gold volumes were approximately 10 percent below the July estimates because of changes to mine plans that delayed access to higher grade material, and a slower than expected ramp-up at the DOZ underground mine. The DOZ mine averaged 48,300 metric tons of ore per day in third-quarter 2012 and is expected to ramp up to 80,000 metric tons of ore per day in 2013. The slower than anticipated ramp-up reflects more extensive repairs required following the 2011 suspension of operations.
