Exxaro Resources has completed a R10.6bn acquisition that materially strengthens its standing in the global manganese market, consolidating stakes in some of South Africa’s most strategic assets as it diversifies beyond coal. The transaction sees Exxaro acquire manganese assets from Ntsimbintle Holdings and OMH Mauritius Corp, marking one of the most significant deals in the sector this year.
The agreement gives Exxaro full ownership of Ntsimbintle Mining, which in turn holds 50.1% of the Tshipi Borwa Mine in the Northern Cape. Tshipi Borwa ranks as the world’s fourth-largest manganese mine by output and is regarded as a long-life, low-cost operation. The deal also includes a 19.99% stake in Jupiter Mines, 100% of Ntsimbintle Marketing, and a 9% interest in Hotazel Manganese Mines, further consolidating Exxaro’s exposure to the manganese value chain.

The move aligns with Exxaro’s stated strategy to rebalance its portfolio as global coal markets face structural and policy pressures linked to decarbonisation. Manganese demand remains closely tied to global steel production, where it is an essential input, but is also increasingly linked to battery chemistries used in electric vehicles and energy storage systems. This dual demand profile has elevated manganese’s strategic importance in commodity markets.
South Africa accounts for roughly 30% of global manganese output and holds an estimated 70% of the world’s known manganese resources, according to U.S. Geological Survey (USGS) Mineral Commodity Summaries. The Northern Cape basin, where Tshipi and other major operations are located, remains central to global supply chains. By deepening its footprint in this region, Exxaro positions itself to benefit from both traditional steel demand cycles and emerging battery-related consumption.
The company funded the acquisition from its cash reserves, reducing a buffer that previously stood between R12bn and R15bn. It recently refinanced R13bn in corporate facilities and indicated it is reassessing capital allocation to better align with commodity price cycles. This suggests a shift from balance-sheet conservatism towards selective growth in minerals deemed critical to future industrial and energy transitions.
The transaction, implemented on 27 February, also carries implications for black economic empowerment participation in the mining sector. The combination of Exxaro and Ntsimbintle brings together two established empowerment-linked groups, reinforcing local ownership in a segment of the resources industry that remains globally competitive.
With this acquisition, Exxaro transitions from a coal-heavy producer to a more diversified mining group with meaningful exposure to manganese. As commodity markets adjust to slower global growth, volatile steel output and accelerating electrification trends, the company’s expanded manganese position places it among the more significant international suppliers in a market increasingly viewed as strategically important.
