Mining company Energy Resources Australia and owner of Kadadu's Ranger uranium mine held its annual general meeting in Darwin today.

Last year the company produced 5,339 tonnes of uranium and brought in a record profit of $222 million.

ERA has also applied to Government for the approval of a new processing technique called 'heat leaching' to be used at the mine and also permission to drill an exploration hole to allow for a possible expansion.

However, the company was criticised by environmental groups in March when the Commonwealth Governments Supervising Scientist found the mine's tailings dam was leaking.

The Northern Territory's Environment Centre Justin Tutty attended today's meeting.

"I'm disappointed that the company has taken no action to halt and retrieve the contamination from the tailings dam.

"We've heard that there's 100,000 litres leaking from there each day, but there's been no action, not even a study on that."

ERA chief executive Rob Atikinson says the company has been monitoring the dam leakage for over 20 years.

"It is very contained to the area around the tailings dam. It is not affecting the waterways in Kakadu in any way.

"There are 28 monitoring points that are regularly reviewed with all data reported to the regulators."

He says the company remains positive about the future of uranium mining in Australia.

"I think for a long time prices have been very depressed and I've got the opportunity to realise the huge potential of the Ranger ore-body.

"We've established good relationships with China and we're certainly looking at that market with a great deal of interest."
