Uranium miner Energy Resources of Australia will not proceed with its proposed 3 Deeps expansion project.



the mine only had the authority to operate until 2021, and the economics of the project required certainty beyond that point.



ERA said it had engaged its major shareholder, Rio Tinto, about funding to rehabilitate the mine site, which is completely ensconced by Kakadu National Park.



The company previously said rehabilitation was funded under its current business plan, but if the 3 Deeps expansion did not go ahead it would require another source of funding to pay for all of the rehabilitation works.
