Rio Tinto Lifts Suspension on RBM’s Zulti South Project, Secures Mine Life to 2050
Rio Tinto Approves R8.5 Billion Zulti South Project to Extend Richards Bay Minerals Mine Life to 2050
Rio Tinto has approved the development of Richards Bay Minerals’ (RBM) Zulti South project, formally lifting the suspension that has been in place since January 2020.
The approximately R8.5 billion (US$473 million) investment is designed to extend the operation’s mine life to 2050 and ensure long-term production stability.
Richards Bay Minerals currently operates within the Zulti North lease area, which includes a mineral separation plant and smelting facility. As the orebody at Zulti North declines, the development of Zulti South is critical to maintaining a consistent supply of zircon, rutile, and ilmenite, and sustaining TiO₂ feedstock sales over the life of the operation.
China Harbour Engineering Company (CHEC) has been appointed as the EPC contractor for Zulti South. The company was selected based on its proven engineering, procurement and construction capabilities, including its strategic partnership with Rio Tinto on the Simandou project in Guinea.
At Simandou, CHEC demonstrated delivery of complex EPC scopes, adherence to HSEC standards, rapid mobilisation, effective integration of global expertise with local execution, and a strong commitment to localisation and community development.
Werner Duvenhage, Managing Director of Rio Tinto Iron & Titanium Africa Operations and RBM, stated:
“Lifting the suspension on Zulti South secures the future of RBM. This project is not about expansion; it reflects our commitment to sustaining jobs and continuing to make a meaningful contribution to the province, the country, and our host communities. The decision to proceed follows improved security conditions and strengthened community partnerships. The support of government, Amakhosi, and host communities has been instrumental in achieving this stability. We remain committed to working with all stakeholders to ensure the project’s long-term success.”
He added:
“CHEC’s strong track record at Simandou, combined with its established presence across Africa, including South Africa, gives us confidence in its ability to deliver Zulti South safely, efficiently, and in alignment with our community and local content commitments.”
Wu Di, Vice President of CHEC, commented:
“We are honoured to be selected as Rio Tinto’s strategic execution partner for Zulti South. Our partnership is built on trust, performance, and shared values. We are committed to delivering a project that strengthens RBM’s future while creating lasting benefits for local communities.”
Construction is expected to commence in the first quarter of 2026, with a projected duration of 30 months. Initial commercial production is targeted for the fourth quarter of 2028.
The first phase will underpin RBM’s supply of zircon and ilmenite, with a second phase to follow as part of the company’s long-term development strategy.
