The Annual General Meeting of Energy Resources Australia, better known as ERA, was held today in Darwin.

While the financial operations of Ranger mine would have been the focus for company officials, environmentalists also had the chance to put forward their views

Issues on the agenda included seepage from the tailings dam.

Dr Stuart Blanch is the head of the Environment Centre Northern Territory; he had a proxie and was able to ask the ERA board about his concerns but he says only some of them were addressed.

"How much water is leaking out of the tailings storage dam at Ranger?

"They say that their monitoring shows it's about 500 litres a day but the office of the supervising scientist, which is a federal environment regulator thinks it might be up to 100 000 litres a day and the CSIRO thinks it might be perhaps up to 150 000 litres a day.

"They're saying they can not actually work out how much water has been leaking and perhaps polluting Kakadu at the bottom of their pit."

Another question he had was in relation to the further exploration the mine will be undertaking and Dr Blanch says there were some answers the company was able to provide on this.

"They say that they will start the Ranger 3 Deeps, which is an underground exploration tunnel, I think in mid-2010, so only a few months away, once the investigations are complete.

"They said that they would not mill any uranium that they found through that process. In fact they said that they're going to avoid finding any uranium."

The ABC approached ERA for comment but the company did not respond.
