SINGAPORE Anglo American Plcs second-quarter copper output rose 14 percent compared with a year earlier due to a strong performance at almost all its projects and is on track to meet its 2013 target.
The London-based companys second-quarter production of 182,900 tonnes of copper was in line with expectations, with all businesses except Mantoverde in Chile recording higher output.
Production at the miners Collahuasi operation in Chile rose 25 percent to 37,700 tonnes on higher ore grades and recoveries despite a planned 49-day shutdown of a semi-autogenous grinding (SAG) mill for a motor replacement that was successfully completed in May, the company said.
Copper output at Los Bronces in Chile increased 13 percent to 101,700 tonnes, with increased mill throughput partially offset by lower ore grades.
Attributable copper sales in the second quarter rose 10 percent to 176,700 tonnes.
"Production guidance for 2013 is maintained at 680,000 tonnes against a backdrop of continued caution around the operating performance recovery and stability, particularly at Collahuasi," the company said.
Anglo Americans second-quarter nickel production fell 22 percent to 8,500 tonnes due to the permanent cessation of production at Loma de Níquel in Venezuela in November 2012.
This was partially offset by higher production at Barro Alto in Brazil, where output increased 13 percent to 6,100 tonnes in the second quarter. Production at Barro Alto continues to ramp up but was affected by a number of stoppages during the quarter. The company expects the facility to produce between 20,000 and 25,000 tonnes of nickel in 2013.
Attributable nickel sales fell 50 percent in the second quarter to 6,300 tonnes.
