Antofagasta plc reported production results for the fourth quarter and full year of 2015. For the quarter, the company's copper production was 169,900 tonnes, 8.2% higher than third quarter 2015. This increase was primarily driven by higher production at Los Pelambres and Centinela Concentrates and the contribution from Antucoya and Zaldívar. Gold production was 55,700 ounces, a 21.8% increase on third quarter 2015 as grades increased at Centinela. Molybdenum production was 2,800 tonnes.

For the year, the company's gold production was 213,900 ounces compared to 270,900 in 2014, mainly reflecting lower grades at Centinela in the second half of the year. Molybdenum production at Los Pelambres was 10,100 tonnes compared to 7,900 tonnes in 2014, as a new, higher grade phase of the pit was mined. Copper production was 630,300 tonnes compared to 704,800 tonnes a year ago.

The company provided production guidance for the year 2016. The group production in 2016 is expected in the range of 710,000 tonnes to 740,000 tonnes of copper, 245,000 ounes to 275,000 ounces of gold and 8,000 tonnes to 9,000 tonnes of molybdenum.
