Glencore Xstrata (GLEN.L) reported that Total own sourced copper production, including copper produced by the nickel and zinc assets, in first-quarter of 2013 was 321,800 tonnes, an 18% increase versus the comparable period, primarily reflected strong growth from Antapaccay, Katanga, Mount Margaret (Ernest Henry) and Mutanda, as they benefit from their respective expansion plans.
African copper produced 83,600 tonnes of copper in metal and in concentrate from own sources during the first-quarter of 2013, a 44% increase compared to the same quarter last year. The expansion projects at Mutanda and Katanga were the main drivers of this growth. Cobalt production from own sources was 3,100 tonnes, an increase of 35%.
The Group's attributable share of own sourced copper production at the Collahuasi joint venture decreased by 13% to 29,400 tonnes mainly due to an expected reduction in grades and a planned shutdown of SAG mill 3 in March 2013, partially offset by improved recoveries. Higher grades and increased mill throughput following the planned SAG mill restart are expected from the second-quarter 2013.
The Group's North American copper assets produced 7,100 tonnes of own sourced copper, a 16% reduction compared to first-quarter of 2012. This decline was primarily due to lower grades.
Total own sourced zinc production, including zinc produced by the copper assets, was 386,900 tonnes in the first-quarter of 2013, broadly in line with first-quarter 2012. This reflected an 11% growth in own sourced zinc production from Australia and the benefit of the Rosh Pinah acquisition, offset by the orderly wind-down of Brunswick and Perseverance.
Total own sourced coal production was 32.7 million tonnes in first-quarter 2013, broadly consistent with the comparable period.
In Kazzinc, gold production for the latest-quarter from own sources was 131,000 toz, an increase of 22% versus the comparable period, driven by higher processing volumes, grades and recoveries at Vasilkovskoye. Total silver production was 4.3 million toz, a reduction of 7% over the comparable period, reflecting a slight decline in the volume of silver-rich third party concentrates processed.
