Iron Ore Division

The iron ore division is made up of the Beeshoek and Khumani mines, both located in the Northern Cape, approximately 200km west of Kimberley. The Beeshoek open-pit operations are situated 7km west of Postmasburg and the Khumani open pits are adjacent to, and south-east of, the Sishen mine, which is operated by Kumba Iron Ore. Khumani Mine supplies iron ore to the export markets and exports are railed to the iron ore terminal at Saldanha Bay. Beeshoek ore is mainly supplied to local customers, with some exported via Khumani.
