Mitsui Iron Ore (Rio Tinto Operations)

Mitsui has been involved in Australia's iron ore industry since the 1960s. We were among the first Japanese companies to establish operations in the Pilbara region in Western Australia.

As a founding partner, Mitsui has a significant investment in the Robe River Joint Venture operated by Rio Tinto in the Pilbara, with interests in the Robe Valley and West Angelas mining hubs, together with major power, rail and port infrastructure.

Our joint venture with Rio Tinto is managed locally by Mitsui’s wholly owned subsidiary Mitsui Iron Ore Development, a team of 12 employees based in Mitsui's Perth office.

Robe River Joint Venture

Robe River is a joint venture between Rio Tinto (53%), Mitsui Iron Ore Development (33%), and Nippon Steel Australia Pty. Ltd. (14%). Operations began in the Robe Valley in 1972 followed by expansion at West Angelas in 2002. Today, Robe River produces approximately 65 million tons per annum of iron ore, which is railed to the port of Cape Lambert where lump and fines product is shipped to steel producers, primarily throughout Asia.

Corporate Social Responsibility

Since 2013 we have partnered with Scitech to support the delivery of a robotics education program within Pilbara primary schools. We also support various other organisations such as Cancer Council WA, West Australian Ballet and the Royal Flying Doctors Service.
