Rio Tinto to invest $1.9 billion to develop the Kangwinan bauxite project in Western Cape York, Queensland
MELBOURNE, Australia, October 22, 2026--Rio Tinto will invest $1.9 billion1 to develop the Kangwinan bauxite project on Western Cape York Peninsula in Queensland, underpinning the long-term future of its Weipa Operations and continued supply to its international customers and its Australian alumina refineries.
Kangwinan highlights Rio Tinto's continued commitment to mining in Australia and will sustain its position as one of the world's leading high-quality bauxite producers.
This brownfield investment will leverage Rio Tinto's project execution capability and reflects continued application of the company's disciplined capital allocation framework. It will add 20 million tonnes of annual bauxite production capacity in Weipa, leveraging some existing infrastructure, with first output targeted in 2029 and full production expected by 2032.
The project will replace production from the Andoom mine near Weipa as it reaches the end of its life this decade, while increasing Weipa Operations' annual capacity to about 44 million tonnes, from current production of around 38 million tonnes per year. It will also help compensate for the planned end of production at the Gove mine in the Northern Territory in 2029.
Rio Tinto Aluminium & Lithium Chief Executive Jérôme Pécresse said: "Kangwinan is a strong vote of confidence in Weipa, in the quality of its bauxite, the capability of its workforce, and the future of the communities and businesses closely connected to our operations.
"The project represents the most significant new mining investment in Queensland in recent years and is a sign of Rio Tinto's long-term commitment to its bauxite business, the State and our integrated mine-to-metal aluminium value chain.
"For more than 60 years, we have operated in Western Cape York, building a world-class bauxite business and enduring relationships with Traditional Owners and local communities. Cultivating and expanding that ongoing partnership will be critical to the long-term success of our operations.
"As Kangwinan moves forward, and with the planned acquisition of the Aurukun Bauxite Project, we will keep listening and working together to create lasting value for Western Cape York, while respecting the connection Traditional Owners have to Country and making sure they continue to benefit sustainably from our operations.
"This investment will support jobs, create opportunities for local and regional businesses, and help us continue supplying our customers with the high-quality bauxite they have relied on for decades."
