The Rudd Government is expecting to declare growth on Queensland's coal-seam gas business during a visit by Chinese consumers.

Experiencing tough political stress to make improvement in the war with miners over the 40% resource super-profits tax, the Government is anticipating to make use of the modified forecasts of profits from the tax, now about $30 billion, to permit higher litheness in negotiations.

But the three large miners, BHP Billiton, Rio Tinto and Xstrata told associate mining corporations yesterday that they aimed to stand their ground in chats and wished to talk about issues of strategy and principle, not imminent taxation proceeds.

In an in-house memorandum to all members of the Minerals Council of Australia, the three largest mining firms assured all the other mining corporations that they were not looking a separate agreement with the Government and would persist to take actions in the welfare of the industry as a group.

The memo said, "BHP Billiton, Rio Tinto and Xstrata have stated they continue to seek a transparent, meaningful and timely consultation process on the RSPT".

The profile of capital and investment and market risk for oil and gas ventures and operations is basically dissimilar to mineral sector projects and functions.
