Rio Tinto will invest $1.8 billion to develop the Brockman Syncline 1 mine project (BS1), extending the life of the Brockman region in the West Pilbara of Western Australia and sustaining production from the company’s world-class iron ore operations.

The project has now received all necessary State and Federal Government approvals and has been developed in consultation with the Puutu Kunti Kurrama and Pinikura (PKKP) Traditional Owners and the Muntulgura Guruma Traditional Owners.

BS1 is a large-scale investment within the Brockman region, which encompasses Brockman 4 and Greater Nammuldi. It will have capacity to process up to 34 million tonnes per annum (Mtpa) of iron ore, leveraging existing plants. First ore is now scheduled for 2027, having previously been anticipated in 2028.

Construction of the project begins this year and includes a new primary crusher and overland conveyor, a Non-Process Infrastructure precinct and a temporary camp for construction workers.

BS1 is one of a tranche of replacement projects, with total annual capacity of ~130Mtpa, that underpin Rio Tinto’s ongoing commitment to the Pilbara. Western Range is more than 90% complete, with first production due in the first half of 2025. The Hope Downs 1 and West Angelas sustaining projects are progressing through approvals processes.

Additionally, work continues on the pre-feasibility study for Rhodes Ridge, one of the world’s largest and highest quality undeveloped iron ore deposits, which is targeting an initial capacity of up to 40Mtpa and first ore by 2030.
