Rio Tinto is seeking to sell its stakes in Australian coal assets, in order to cut operational costs due to low coal prices and increase shareholder returns.
The mining giant has hired Deutsche Bank to handle the sale of Clermont and Blair Athol thermal coal mines in the state of Queensland, which is expected to generate more than $1bn, reported The Wall Street Journal.
Rio Tinto is also planning to offload a stake of up to 29% in its Coal & Allied Industries unit in the state of New South Wales.
The company holds an 80% interest in Coal & Allied Industries, which operates several mines in the state.
Analysts earlier estimated that the company will need to divest or close some of its operations in order to reach its target of cutting costs by over $5bn by the end of 2014.
Rio Tinto's new CEO Sam Walsh made a commitment to increase value for shareholders and announced that cash would be raised from divestures this year.
The company had put its Canadian iron-ore operations up for sale and is reviewing its diamonds and Pacific Aluminium operations too, the WSJ reported last month.
The Clermont mine, which opened in 2010, is being offered as one package with the Blair Athol mine to the buyer.
Rio Tinto, which owns a 50.1% stake in the mine, laid off workers when thermal coal prices dropped in September 2012.
The company stopped operations at Blair Athol mine, which produced approximately 250 million metric tonnes of thermal coal, in November 2012, citing a reduction in commodity prices, increasing mining costs and a high Australian dollar.
Operations at this mine were also halted due to depletion of coal seams, which impacted the quality of coal production.
Rio Tinto is the latest firm seeking to divest its stake in mining assets in Australia.
BHP Billiton recently identified its ten non-core operations, including Queensland's Gregory Crinum coking coal mine, to be put up for sale in order to cut costs.
Global miner Xstrata also announced its plans to merge its New South Wales and Queensland divisions under a single entity, Xstrata Coal Australia, citing industry's tough economic conditions.
