Rio Tinto Commits $473M to Zulti South to Extend Operations to 2050
Rio Tinto has approved a $473 million investment to restart Richards Bay Minerals’ Zulti South project in South Africa, extending mine operations through 2050 and securing zircon, rutile and ilmenite supply. EPC contractor China Harbour Engineering will begin construction in Q1 2026 with initial commercial output expected by Q4 2028.
1. Investment Approval and Strategic Impact
Rio Tinto has lifted the suspension of the Zulti South project with a $473 million commitment, securing Richards Bay Minerals’ operations until 2050. The funding ensures continued supply of zircon, rutile and ilmenite and underpins long-term titanium dioxide sales.
2. Project Timeline and Production Outlook
Construction is slated to begin in Q1 2026 and span 30 months, with initial commercial production anticipated by Q4 2028. The first phase will prioritize zircon and ilmenite output, aligned with RBM’s phased development plan.
3. EPC Partnership and Community Support
China Harbour Engineering was selected as the EPC contractor based on its performance at Simandou and strategic alignment with Rio Tinto values. Improved security conditions and strengthened host-community partnerships were key factors in reactivating the project.
