Mining giant Rio Tinto is selling its stake in its Australian coal mine Bengalla for $606m (£399m).
The 40 per cent stake has been bought by specialist miner New Hope Corporation. Bengalla is the smallest of three coal mines in the Hunter Valley in which Rio Tinto holds an interest.
Deutsche Bank advised Rio on the deal.
It is one of a series of $4.5bn-worth of divestments made by the firm sine January 2013 as it looks to focus on more profitable commodities.
Rio Tinto Copper & Coal chief executive Jean-Sébastien Jacques said "This sale will deliver value for our shareholders as we remain focused on continuing to develop the strongest core portfolio of assets in the mining industry.
