Rio Tinto also announced that it is advancing development at Rhodes Ridge. A pre-feasibility study is expected to be completed this year, and the project is slated to begin production in 2030.

Rio Tinto PLC (RIO) shares fell as much as 2% in morning trade on Wednesday after Japan's Mitsui & Co. (MITSY) signed agreements to acquire a 40% interest in the Rhodes Ridge Joint Venture (RRJV), a major mining project in Australia, from Rio Tinto's existing partners.

The deal, subject to regulatory approvals and other conditions, strengthens Mitsui’s presence in Australian mining and leaves Rio Tinto's 50% stake in the project unchanged. 

Mitsui agreed to purchase the entirety of VOC Group’s 25% interest in the venture and separately entered a heads of agreement to acquire an additional 15% from AMB Holdings Pty. 

If the second transaction closes, AMB Holdings will retain a 10% stake.
