The Northern Territory Government has reiterated its opposition to uranium mining at a deposit near a major sacred site in Kakadu National Park.

The Koongarra deposit sits only three kilometres from Nourlangie Rock, a site of sacred traditional art visited by thousands of people every year.

But unlike Nourlangie, Koongarra is not within the boundaries of the National Park and federal changes would be necessary to absorb the site into the world heritage area.

Territory Environment Minister Len Kiely says it is up to the Commonwealth and traditional owners to include the deposit area in the National Park.

But he says the Territory Government remains unmoved on the issue.

"We don't want mining in Koongarra so close to Nourlangie Rock," he said.

"This is a place of great significance to all Territorians, high visitor numbers, a place of extreme beauty."

"We restate our position we went to the last election on. We don't want mining in Koongarra next to Nourlangie Rock."

The Northern Land Council (NLC) says it is waiting to hear whether traditional owners will allow the uranium deposit to be mined by a French company.

NLC chairman Wali Wunungmurra says the traditional owners have not told him what they want to do yet.

"I would rather listen to the traditional owners because they could or could not change their minds," he said.

"We just have to work with the traditional owners and let them give us the OK whether to make a deal or no deal."

"It's up to the traditional owners really to decide what to do with their land."
