Rio Tinto has sold its remaining coal asset, a stake in the Kestrel underground coal mine in central Queensland.

According to Rio Tinto chief executive J-S Jacques, this leaves Rio Tinto’s portfolio stronger and more focused, now consisting of operations in iron ore, aluminium, copper and bauxite. 

Chief executive of the Responsible Investment Association Australasia Simon O'Connor said the miner is now cleaner and greener which pivots Rio Tinto into a position where some investors may consider investing in Rio Tinto again.
