Rio Tinto has approved a $473 million investment to restart and complete the Zulti South project at its Richards Bay Minerals operation in South Africa, lifting a suspension that had been in place since January 2020.
The project is designed to extend the life of the Richards Bay mine to 2050 and ensure operational continuity for the business. 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, Zulti South is expected to maintain a stable supply of zircon, rutile and ilmenite, supporting TiO₂ sales over the remaining life of the mine.
China Harbour Engineering Company has been appointed as the engineering, procurement and construction contractor for Zulti South. The company previously partnered with Rio Tinto on the Simandou project in Guinea and was selected based on its delivery of complex EPC scopes, compliance with health, environment, safety and community standards, rapid mobilisation and commitment to localisation and community engagement.
Construction is expected to begin in the first quarter of 2026 and take approximately 30 months to complete. Initial commercial production is targeted for the fourth quarter of 2028. The first phase will support supply of zircon and ilmenite, with a second phase planned as part of the long-term development strategy.
The decision to proceed follows improved security conditions and strengthened community partnerships in the region, according to the company.
KEY QUOTES
