Miners are threatening to restart anti-tax campaign, potentially bringing back the controversy over the government's resource levy.

The big miners' lobby, the Minerals Council of Australia (MCA) placed ads in last weekend's News Limited newspapers publicising the contribution of the mining industry to the economy.

It, however, said these advertisements were not connected with political matters and added it had no intent to influence the three independents - Rob Oakeshott, Tony Windsor and Bob Katter - during their discussions with Labor and Coalition.

The council said it had not talked with any of the three MPs although Fortescue Metals chief executive Andrew "Twiggy" Forrest met Mr Oakeshott last week.

The Association of Mining and Exploration Companies (AMEC) and its hundreds of mid cap mining and junior exploration company members, meanwhile, are against any mining profits tax.

AMEC chief executive Simon Bennison said it may relaunch its advertising campaign.

"We are very keen ourselves to be involved in promoting the benefits, particularly economic benefits, of the resource sector to the Australian economy and this is one way of doing it," he said.

"I think it was very clear from this whole process of tax reform that began some months ago on May 2. That demonstrated that a lot of people just don't appreciate and understand what the mining industry in particular contributes to the Australian economy.

"We make sure that they fully appreciate that if they make the resource sector uncompetitive through higher taxes, which is being proposed, in that economic production that drives a country is going to be lost."

Mr Bennison said the advertisements are not aimed at pressuring the independents.

"I don't think that is the intention of the MCA, but you would have to ask the MCA that," he said.

"Part of the objective is that we recognise it is important to promote the resource sector and it is far more than what we have been doing and its role in the community in particular."

"[But] I think the independents are beyond influencing. They have got enough on their plate at the moment in trying to do what they have to do."
