The last chapter in one of Australia’s biggest environmental battles is set to play out after mining giant Rio Tinto moved to take full control of the controversial Ranger uranium mine near the World Heritage-listed Kakadu National Park.
Rio, the world’s second-biggest miner by market value, told the Australian stock exchange on Wednesday it will compulsorily acquire the remaining shares it does not own in its subsidiary Energy Resources of Australia (ERA), taking control of the contentious Ranger uranium mine and neighbouring Jabiluka deposit, one of the world’s richest known sources of untapped uranium.
The Ranger uranium mine in the Northern Territory, owned by ERA, stopped mining in 2021. Now it is a big and costly clean-up job.
ERA stopped mining uranium oxide operation at Ranger in 2021, but the cost of rehabilitating the mine is on track to exceed $2.2 billion and concerns have lingered among traditional owners, the Mirarr people, about ERA’s intentions, particularly after it applied for a 10-year mining lease extension over Jabiluka in March this year.
Rio, which owned a large stake in ERA, began working with ERA on rehabilitating the mine in 2021. ERA was legally required to rehabilitate the operation by 2026 estimating it would cost $500 million, but budget blowouts and differences between ERA’s board and Rio led to a fractious relationship with its majority shareholder before Rio reached an agreement with ERA to take over management of the mine’s rehabilitation in April this year.
The push to mine Jabiluka at one stage sparked fierce opposition among traditional owners and environmental campaigners in 1998. Thousands of protesters took part in a human blockade at the site and hundreds were arrested in the ensuing clampdown.
The lease area covers a sacred site with hundreds of ancient rock art galleries. In the end, Jabiluka was never mined, and ERA pledged it would not develop the area as long as the Mirarr remain opposed to it.

Rio’s Australia chief executive Kellie Parker reaffirmed the dual London-Australia listed miner had “no intention to invest in mining or development of the Jabiluka deposit”.
“Proceeding with compulsory acquisition, after participating for our full entitlement in the ERA capital raising, underlines our commitment to Ranger’s rehabilitation,” Parker said.
