The company behind the Ranger Uranium Mine in Kakadu National Park has told shareholders it would be delighted to extend the life of the mine.

Energy Resources of Australia held its Annual General Meeting in Darwin this morning.

Under current legislation, work at the mine has to stop in 2021.

The company's chief executive, Rob Atkinson, says there is no plan to extend it at this stage, but that could change if further resources are found.

"I think we've got an exciting exploration program in the future and really depending on that feasibility, that if there's efficient ore and that we can work with the key stakeholders, then I think that it would be a desirable option."

The environment centre's Justin Tutty was at the meeting and says the comments are disappointing.

"It's absurd to realise that at a time when the miner should be looking to address their pollution issues in Kakadu, instead they're focussed on expansion."
