Rio Tinto has officially resumed its Zulti South project at Richards Bay Minerals with a $473 million investment, ending a suspension that began in January 2020. This resurgence comes as the company celebrates a robust 11% year-over-year growth in copper production for 2025, reaching 883 kilotonnes, while also focusing on low-carbon copper production at the Johnson Camp.

Despite the recent termination of merger discussions with Glencore, Rio Tinto's future projects, including a desalination initiative in partnership with the Western Australian Government, bolster its strong revenue and earnings growth forecasts of 10.7% and 21.8%, respectively.
