The company’s total hard coking coal production came to 4.1 million tonnes for the half year, with the $2 billion investment in the Kestrel South extension beginning to pay off for Rio.
Semi-soft coking coal production was 5% higher than the first half of 2014 reflecting mine production sequencing at the Hunter Valley Operations in New South Wales.
Semi-soft coking coal production was 1.9Mt for the half.
Thermal coal production was in line with the first half of 2014 at 8.8Mt with increased tonnage at Hail Creek through a processing plant by-product stream and a strong operational performance which was offset by the impacts of wet weather in the Hunter Valley.
For 2015, Rio Tinto’s share of production is expected to be 18 to 19Mt of thermal coal, 3.0 to 3.4Mt of semi-soft coking coal and 7.1 to 8.1Mt of hard coking coal.
