PERTH, Australia, February 19, 2025--(BUSINESS WIRE)--Rio Tinto notes that Mitsui & Co. has entered agreements to acquire a 40% interest in the Rhodes Ridge Joint Venture (RRJV) from Rio Tinto’s partners.

Mitsui & Co. has agreed to acquire all of VOC Group Limited’s (VOCG) 25% interest¹ in the joint venture.

Separately, Mitsui & Co. has entered into a heads of agreement (HOA) to acquire a further 15% interest in the RRJV from AMB Holdings Pty Ltd¹.

Both transactions are subject to regulatory approvals and other closing conditions.

Mitsui & Co. and Rio Tinto are long-standing partners at the Robe River Joint Venture². Rio Tinto welcomes Mitsui & Co. to Rhodes Ridge and looks forward to progressing the project.

Rio Tinto's 50% interest in the RRJV and the terms of the joint venture arrangements are unchanged.

Under the HOA, AMB Holdings Pty Ltd would retain a 10% stake in the RRJV.

A pre-feasibility study to progress the development of Rhodes Ridge is expected to be completed this year, with a feasibility study to follow. The development would use Rio Tinto’s rail, port and power infrastructure.

First ore from Rhodes Ridge is expected by 2030.
