Rio Tinto Invests $1.8bn in Brockman Mine Extension to Secure Long-Term Iron Ore Supply

Rio Tinto has committed $1.8 billion to extend its Brockman iron ore operations in Western Australia’s Pilbara region. This investment supports the Brockman Syncline 1 (BS1) mine project. The extension will help ensure a steady supply of iron ore for decades. Construction will start in 2024 and aims to process up to 34 million tonnes annually.

Key Developments in the Brockman Syncline 1 Mine Project

The BS1 project received all necessary approvals from both state and federal governments. It is a partnership with the Puutu Kunti Kurrama and Pinikura (PKKP) and the Muntulgura Guruma Traditional Owners. The project will incorporate Brockman 4 and Greater Nammuldi deposits. It will use existing plants to increase the ore processing capacity.

Rio Tinto will begin construction this year. New additions include a primary crusher, an overland conveyor, and a Non-Process Infrastructure precinct. A temporary construction camp will also be built. First ore production from BS1 is expected by 2027, a year earlier than planned.

Economic and Employment Impact

Simon Trott, CEO of Rio Tinto Iron Ore, stated the BS1 project would secure the life of the Brockman hub. “This project is good for our business, Western Australia, and the Australian economy,” Trott added.

The construction phase will create 1,000 jobs. The operational phase will sustain 600 jobs. BS1 is part of a series of new projects in Pilbara. These projects will collectively produce around 130 million tonnes annually.

Rio Tinto’s Expanding Portfolio of Iron Ore and Lithium Projects

The BS1 project is one of several key projects for Rio Tinto. The Western Range project is 90% complete and will start production in the first half of 2025. Other projects, including Hope Downs 1 and West Angelas, are going through approval.

Additionally, Rio Tinto acquired Arcadium Lithium in October 2024 for $6.7 billion. This acquisition positions Rio Tinto as a major player in lithium production. The company aims to produce over 200,000 tonnes of lithium carbonate equivalent (LCE) annually by 2028.
