Who we are



Energy Resources of Australia Ltd (ERA) is a publicly listed company with Rio Tinto as its major shareholder. ERA, established in 1979, previously mined and produced uranium oxide from its Ranger mine in the beautiful and rugged Alligator Rivers area of the Northern Territory. The Ranger mine is located on Aboriginal land, surrounded by, but currently separate from, Kakadu National Park.


ERA’s production operations on the Ranger Project Area ceased in January 2021, with the major focus now shifting to the comprehensive world-class rehabilitation of the Ranger mine that will eventually allow it to be incorporated back into the Kakadu National Park should the Traditional Owners and the Commonwealth Government wish.

The Ranger Rehabilitation Project is the largest project of its kind in Australia and possibly the world. It is unique in that it is rehabilitating land in one of the world’s most culturally and environmentally sensitive locations, surrounded by the World Heritage-listed Kakadu National Park on the land of the Mirarr Traditional Owners, located three hours southeast of Darwin.

About Rio Tinto

Rio Tinto is a leading global mining and materials company. We operate in 35 countries where we produce iron ore, copper, aluminium, critical minerals, and other materials needed for the global energy transition and for people, communities, and nations to thrive.

We have been mining for 150 years and operate with knowledge built up across generations and continents. Our purpose is finding better ways to provide the materials the world needs – striving for innovation and continuous improvement to produce materials with low emissions and to the right environmental, social and governance standards. But we can’t do it on our own, so we’re focused on creating partnerships to solve problems, create win-win situations and meet opportunities.


Every Voice Matters

At Rio Tinto, we particularly welcome and encourage applications from Aboriginal and Torres Strait Islander people, women, the LGBTI+ community, mature workers, people with disabilities and people from different cultural backgrounds.

We are committed to an inclusive environment where people feel comfortable to be themselves. We want our people to feel that all voices are heard, all cultures respected and that a variety of perspectives are not only welcome – they are essential to our success. We treat each other fairly and with dignity regardless of race, gender, nationality, ethnic origin, religion, age, sexual orientation or anything else that makes us different.
