Rio Tinto completes sale of its stake in Rössing Uranium Limited

16 July 2019

Rio Tinto has completed the sale of its entire interest in the Rössing uranium mine in Namibia to China National Uranium Corporation Limited (CNUC) for an initial cash payment of $6.5 million plus a contingent payment of up to $100 million.

Rio Tinto chief executive J-S Jacques said “This sale demonstrates Rio Tinto’s commitment to further simplifying and strengthening our portfolio and brings the total divestment proceeds received since 2017 to $11.2 billion, of which $9.7 billion has been returned to our shareholders.

“I would like to recognise the hard work of people across Rio Tinto and the communities around Rössing who have contributed to the success of the mine and wish them all the best for the future under new ownership.”

The $100 million contingent payment is linked to uranium spot prices and Rössing's net income during the next seven calendar years. In addition, Rio Tinto will receive a cash payment if CNUC sells the Zelda 20 Mineral Deposit during a restricted period following completion.
