Global mining giant Rio Tinto has confirmed it will proceed with the long-awaited Zulti South Project in KwaZulu-Natal, lifting a five-year suspension and committing R8.5-billion (USD473-million) to extend the life of its Richards Bay Minerals (RBM) operations until 2050.
This investment secures a stable supply of zircon, rutile, and ilmenite—critical minerals used in ceramics, paints, and titanium dioxide production—while safeguarding jobs, supporting export revenues, and reinforcing Rio Tinto’s long-term commitment to host communities in the province.
Why Zulti South Matters
RBM currently operates within the Zulti North lease area, which includes a mineral separation plant and smelting facility. As the orebody at Zulti North declines, Zulti South becomes essential to maintaining production capacity and ensuring continuity of supply for global markets.
The project is not about expansion—it’s about sustainability and stability. By unlocking Zulti South, Rio Tinto is ensuring that RBM remains a cornerstone of South Africa’s mineral economy for decades to come.
Strategic Partnership with CHEC
Rio Tinto has appointed China Harbour Engineering Company (CHEC) as the EPC contractor for Zulti South. CHEC’s selection reflects its proven track record on Rio Tinto’s Simandou project in Guinea, where it successfully delivered complex scopes while meeting stringent health, safety, environment, and community (HSEC) standards.
CHEC brings global expertise combined with local execution, rapid mobilisation, and a strong commitment to localisation, supplier development, and community engagement—all critical factors for a project of this scale.
Wu Di, Vice-President of CHEC, emphasised: “Our relationship with Rio Tinto is founded on trust, performance and shared values. We are committed to delivering a project that strengthens RBM’s future and benefits local communities.”
Commitment to Communities and Stability
Werner Duvenhage, Managing Director of Rio Tinto Iron and Titanium Africa Operations and RBM, highlighted the importance of the decision: “Lifting the suspension on Zulti South means securing the future of RBM. This project represents our commitment to sustaining jobs and continuing to make a meaningful contribution to the province, the country and the host communities. Improved security conditions and strengthened community partnerships have been vital in establishing this stability.”
The support of government, traditional leaders (Amakhosi), and host communities has been instrumental in creating the conditions for the project to move forward.
Timeline and Phases
- Construction Start: Q1 2026
- Duration: 30 months
- Initial Production: Q4 2028
The first phase will support RBM’s supply of zircon and ilmenite, while a second phase will follow as part of the long-term development strategy. Together, these phases will ensure RBM’s operations remain viable until at least 2050.
Economic and Strategic Impact
The Zulti South Project represents more than just a mining investment—it is a strategic commitment to South Africa’s economy. By securing jobs, stabilising exports, and reinforcing community partnerships, Rio Tinto is positioning RBM as a long-term contributor to both local development and global supply chains.
For South Africa, the project underscores the importance of balancing resource sustainability, community engagement, and economic growth in the mining sector.
Final Thoughts
The revival of Zulti South signals a turning point for RBM and the communities of KwaZulu-Natal. With R8.5-billion invested, improved security conditions, and strong partnerships in place, the project is set to deliver stability, opportunity, and long-term growth.
As construction begins in 2026, all eyes will be on how Rio Tinto and CHEC deliver on their promises—ensuring that Zulti South not only sustains RBM’s future but also strengthens South Africa’s position in the global mineral economy.
