The Territory Government is courting major resources companies at a conference in Alice Springs today.

More than 200 delegates are at the Annual Geoscience Exploration Seminar at the Alice Springs Convention Centre.

The Minister for Mines and Energy Chris Natt says the Territory is under-explored in terms of mining, and the Government wants more companies to begin operations.

"Everyone must understand that mining is the largest contributor to our economy at the moment and the resources industry virtually underpins much of the Territory's strong economic growth.

"So we're trying to get out there just to let everyone know that really the Territory is a vast expanse of land, there's a lot of prospective areas and really the Territory remains under-explored."

Exploration licences were recently granted for uranium and petroleum in Central Australia, and Mr Natt says more mining activity can be expected in the region.
