Glencore Xstrata has posted a 26% increase in yearly copper output, bolstered by strong growth at its African and Chilean mines.
African copper was up 43% to 398 600 tonnes, as key expansion projects, Katanga and Mutanda, grew production successfully, both achieving a 200 000 tonne a year capacity at the end of 2013.
Collahuasi increased production by 58% to 195,600 tonnes, with H2 2013 up 91% compared to H1 2013, as production ramped up, following the SAG mill restart and a return to higher grades.
Meanwhile the Antapaccay and Ernest Henry projects are progressing well.
Perseverance and Brunswick mines reached the end of their mine lives in June 2013, resulting in a decline in total own sourced zinc and lead production, only partially offset by the growth projects in Australia and Africa.
Excluding Perseverance and Brunswick, zinc production increased by 7% in 2013.
Koniambo started production in Q4 2013 and is in the early stages of ramp-up.
Ferrochrome production was up 32% to 1.2 million tonnes, based on higher utilisation of the smelters and furnaces and the successful commissioning of the Tswelopele pelletizing plant.
Own sourced gold production was up 14% to 1.023 million oz, driven by strong growth at Kazzinc and Antapaccay.
Coal production was up 4% to 138.1 million tonnes during 2013, driven by a number of key expansion projects at Prodeco and various Australian thermal coal assets.
