Energy Resources of Australia Ltd is Australia’s longest continually-operating uranium mine and one of the country’s largest uranium producers. Uranium has been mined at Ranger for more than three decades and it is one of only three mines in the world to have produced in excess of 120,000 tonnes of uranium oxide.

Rio Tinto owns 68.4 per cent of ERA shares. The balance of the company’s shares are publicly held and traded on the Australian Securities Exchange.

Ranger began commercial production of drummed uranium oxide (U3O8) in 1981. In November 2012, mining in the operating Pit 3 ended.

ERA sells its product to power utilities in Asia, Europe and North America under strict international and Australian Government safeguards to ensure that Australian uranium is only used for peaceful purposes. It maintains long-term relationships with customers and meets their energy needs by providing consistent and reliable supply of uranium oxide.


Located 8km east of Jabiru and 260km east of Darwin, in Australia’s Northern Territory, ERA’s Ranger mine lies within the 79km2 Ranger Project Area.

The Jabiluka deposit also held by ERA is 22km north of Ranger. This world-class deposit is under long-term care and maintenance and, in accordance with the Jabiluka Long Term Care and Maintenance Agreement, will not be developed by ERA without the approval of the Mirarr Traditional Owners.

The Ranger Project Area and the Jabiluka lease are located on Aboriginal land, and surrounded by, but separate from, the World Heritage listed Kakadu National Park.
