Diversified miner Xstrata released its 2012 production report for the year ended 31 December 2012, highlighting thermal coal production of 90.4 million tonnes.
The figures represent a 7% increase when compared to 2011 levels and were attributed to the successful commissioning of the Ravensworth North, Ulan West and Ulan open cut projects in Australia.
"We completed, on schedule, the first stage of the eight million tonne per annum Ravensworth North thermal coal operation in New South Wales. The second stage, the expansion of the existing coal preparation plant, is on schedule for completion in 2013," the company said in a statement.
Productivity improvements at Cerrejón and the continued transition of South African thermal coal operations into large-scale, low-cost operations also contributed to the increase.
Australian coking coal production, meanwhile, declined 9% on previous year figures to a total of 6.9 million tonnes.
Xstrata's copper production demonstrated a 16% decline, as a result of a transition from older, depleted mines to new mines and expanding operations.
"Our production steadily increased during 2012 as we commissioned and/or ramped up five organic growth projects reaching an annualised production rate of approximately 900,000 tonnes in December 2012 compared to 700,000 tonnes in January 2012," said Xstrata
The Glencore-Xstrata joint copper production for 2012 also recorded a 9% decline.
Production across Xstrata's other commodities such as coal and zinc increased 7% and 8% respectively in 2012 compared to 2011 production figures.
The company's nickel production totaled 106,873 tonnes in 2012 supported by a full year's production of 15,186 tonnes in ferronickel from the Falcondo operation in the Dominican Republic, which operated 7% above its current nameplate capacity.
