Energy Resources of Australia has made it clear it wants to mine the Jabiluka uranium deposit within the Kakadu National Park.

ERA owns and operates the nearby Ranger uranium mine, which provides the fuel for one per cent of the world's electricity.

At the company's annual general meeting in Darwin today, shareholders were told the company is relying on the approval of a $36 million processing facility to recover an extra 20,000 tonnes of uranium oxide.

The company has a mining lease until 2021, but told the meeting it would love to exploit the contentious Jabiluka deposit.

The company says it has the highest grade of uranium in the world, but it will not consider mining it without consent from the Mirrar people.

No traditional owners were at the meeting, but they have repeatedly said they do not want Jabiluka mined.

Meanwhile, ERA chief executive Rob Atkinson told shareholders Kakakdu National Park is not being contaminated by operations at the Ranger mine.

Company executives were probed about leakage at the mine's tailings dam.

Environmentalists say up to 150,000 litres of contaminated water is leaking everyday into areas of Kakadu National Park.

Mr Atkinson says that is wrong and misleading.

He says monitoring shows about 500 litres per day are leaking and not one drop has left the mining lease area.

He says ERA is planning to build a workers' village near Jabiru to house up to 800 staff for a proposed heap leach facility.

"What we have decided to build on our lease is a village that could accommodate up to 800 people in a good environment that are well and truly contained so not having Jabiru inundadeted with [workers]."
