Treasurer Wayne Swan claimed on Sunday that several mining companies privately surrendered to the Federal Government on its proposed resource super tax profits.

Mr. Swan told media yesterday some miners were publicly against the new tax but they expressed their sentiments privately with the government, admitting they can pay more tax.

He did not disclose which companies have admitted privately.

The proposed 40 per cent tax on super profit will renew the 20-year old royalty based taxation system that the government believes did not help boost profits in the resource sector.

"The miners know, in their heart of hearts, that they are going to have to pay a bit more because the royalties regimen has not kept pace with the value of this resource, which is 100 per cent owned by the Australian people," Mr Swan told a local television program.

Mr. Swan stressed that removing the existing tax and revising it with a better one would help grow the industry for a longer period.

"But some very profitable ventures will pay more, and they do recognise privately that they do need to pay a lot more."

Mr. Swan confirmed he will meet with 80 mining executives this week to negotiate on a “generous transition provisions” but did not mention any alteration to the super profits tax.

Many mining executives have expressed their rejection over the 40 per cent mining tax after it was released on May 2 as part of the government's response to the Henry Tax Review.

Tom Albanese, chief executive of Rio Tinto, have publicly lambasted the government for calling Australia's largest miners “outsiders” due to their solid base of foreign ownership.

BHP Billiton Marius Kloppers and miner Clive Palmer both agreed the government was seeking to destroy the economy with a tax that is the same to communism.

Despite the negative feedbacks from mining companies for a span of two weeks, Labor spokesperson Craig Emerson said that with several miners admitting privately on the super tax profits, it means that they agree on the high levels of mineral development in Australia.
