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 has produced in excess of 128,000 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 south 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 consent 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.


Sustainable development

Protecting the environment

The Australian Government's Supervising Scientist Division monitors the impact of uranium mining on the environment and people in the Alligator Rivers region.


ERA has a diverse workforce with female and Aboriginal and Torres Strait Islander employees' participation being 18 per cent and 13 per cent respectively of all ERA full-time equivalent employees at the end of 2018.

ERA is a leading employer of Indigenous people in the Northern Territory and a principal employer in the West Arnhem region. ERA’s Indigenous employees are employed in positions at many levels within the company, from operations to human resources to leadership roles.

Rehabilitation and mine closure

Under the current Ranger mine lease, production operations must cease by January 2021 and the site must be rehabilitated by 2026. ERA has been progressively rehabilitating Ranger in line with our regulatory obligations. Since 2012 ERA has spent $511 million on rehabilitation and water management activities. ERA's Ranger Mine Closure Plan was released publicly and approved by relevant Ministers in 2018 and will be updated annually.
