Exxaro, which previously disposed of a stake worth $474 million, said in a statement it plans to further disinvest from its remaining 24 percent stake "in a thoughtful, efficient and staged process over time."
The miner, which holds 28.7 million shares in Tronox, said its remaining stake is valued at around $476 million assuming a share price of $16.57 per share.
Exxaro, which mainly produces coal, completed its sale of 22.4 million shares in Tronox in October last year and paid a special dividend of 4.5 billion rand ($377 million) from its income reserves after selling the stake. (Reporting by Tanisha Heiberg Editing by Alexander Smith)
