Rio Tinto invites EOIs work package for the Kangwinan bauxite mine

Global mining firm Rio Tinto has opened full-scope expressions of interest (EOIs) for three key work packages for its Kangwinan Project, part of a major expansion of bauxite operations on Cape York Peninsula. The EOIs, available from October 13, will cover the concrete batch plant, site survey services, and the supply of quarry materials, marking a key milestone in advancing the project to its next phase.

Located on Norman Creek, around 60 km south of Weipa, the Kangwinan Project will establish a new bauxite mine and expand the Amrun port, potentially doubling output from Rio Tinto’s Weipa Southern Operations. The project aims to offset declining production as the Gove and Andoom mines approach closure.

Feasibility and approvals are underway

Rio Tinto is currently advancing a detailed feasibility study that will inform a final investment decision expected by the third quarter of 2026. Future procurement and contracting decisions will hinge on board approval. Bechtel Australia is serving as the engineering, procurement, and construction manager (EPCM), though Rio Tinto will retain control of major contracting.

If approved, construction will span 32 months, creating over 800 construction jobs while sustaining employment for existing Weipa workers. Early works include a 250-room camp at Amrun Village and an access road to the Kangwinan site. Plus, this project will also establish a mining centre 15 kilometres south-east of Amrun, constructed at a cost of US$1.9 billion and commissioned in 2018

A step forward for sustainable operations

Rio Tinto’s Pacific Operations Aluminium Managing Director, Armando Torres, said, “This feasibility study will explore a new bauxite operation at our Weipa Operations and represents a strong vote of confidence in the world-class bauxite deposits on the Western Cape York Peninsula, our bauxite operations, and the local community.”

Commenting on the study, he added, “It’s an important step toward securing the long-term future of our operations at Cape York while ensuring security of supply to our Australian refineries and to our customers.”

Cultural and regional collaboration

Named Kangwinan at the request of the Wik Waya people, the traditional owners of the land, the project underscores Rio Tinto’s continued engagement with Indigenous communities. With production targeted for 2029, Kangwinan is set to sustain regional economic growth and strengthen Australia’s position in the global aluminium supply chain.
