Rio Tinto Limited
(ASX:RIO) expects its Oyu Tolgoi mine's production to double in 2014, compared with this year.
Rio subsidiary, Turquoise Hill Resources, which owns 66 per cent of the Mongolian mine, says it expects to produce between 150,000 and 175,000 tonnes of copper in concentrates at the mine in 2014.
This compares with a forecast of 75,000 to 85,000 tonnes of copper in concentrates for 2013, which the miner reaffirmed in October.
The miner says it expects to produce between 700,000 and 750,000 ounces of gold in concentrates in 2014.
Operating cash costs are expected to be approximately $US1 billion and capital expenditure is set to be $US160 million.
Rio Tinto delivered a net profit of $1.8 billion in the first half of fiscal 2013.
