Rio Tinto Invests $733 Million to Extend Life of West Angelas Iron Ore Hub

Rio Tinto (ASX:RIO) has announced a major $733 million investment, alongside partners Mitsui Iron Ore and Nippon Steel (TYO:5401), to extend the operational life of the West Angelas iron ore hub in Western Australia’s Pilbara region. The project, part of the long-standing Robe River Joint Venture, aims to sustain production at around 35 million tonnes annually and secure the hub’s future for years to come.

Rio Tinto’s share of the investment totals $389 million, reflecting its 53% ownership stake in the joint venture. Mitsui holds 33%, while Nippon Steel owns the remaining 14%. According to Rio Tinto, all necessary state and federal approvals have been secured, and development of new deposits is set to begin soon. The company expects to deliver the first ore from the expansion by 2027.

The West Angelas expansion will leverage existing processing infrastructure, minimizing environmental impact while maximizing efficiency. The project is expected to create approximately 600 construction jobs and sustain around 950 ongoing operational roles once fully operational. This initiative supports Rio Tinto’s broader strategy of maintaining its strong production base in the Pilbara region, a critical supplier of high-quality iron ore to global steelmakers.

Rio Tinto’s shares on the ASX rose about 1% in early trading following the announcement, reflecting investor confidence in the long-term value of the expansion. The mining giant emphasized that continued investment in Pilbara operations reinforces its commitment to reliable supply, innovation, and sustainable mining practices.

By extending the West Angelas hub, Rio Tinto and its partners aim to secure the joint venture’s production stability while supporting the local economy and global demand for iron ore — a key raw material in steelmaking and industrial growth.
