An anti-nuclear campaigner says the Northern Territory Government is becoming increasingly nervous about a proposal for a uranium mine, 25 km south of Alice Springs.

A public meeting in Alice Springs has called for the Mines Minister, Kon Vatskalis to come and address the town's concerns about the Angela Pamela prospect.

The NT Government granted an exploration licence over the site to Cameco-Palladin last month.

Dr Jim Green, from Friends of the Earth says the meeting resolved to pressure the Government to keep the Territory nuclear free.

"I'm sure that they're nervous and one illustration of that is the Northern Territory Government has letterboxed the entire town of Alice Springs in relation to the Angela-Pamela Uranium mine," Dr Green said.

"They must be nervous and they'll be all the more nervous after this weekend, especially seeing 140, 150 people turning up to a public meeting directly after a severe storm on Friday night."

The lobby group will raise concerns at tonight's Alice Springs Town Council meeting about the proposals.

Dr Green says the group is also concerned about BHP Billiton's proposed expansion of uranium mining in South Australia.

He says if it goes ahead, there would be one train a day carrying uranium through Alice Springs for the next decade.

"The issue that I'll be raising with council is, have they assessed the possibility or the probability of a train accident over that period of time given that there have already been derailments on that train line and also the economic costs of an accident if it occurs," he said.
