The revised bid comes days after Resource Pacific completed the initial stage of an entitlement offer that aims to raise $A165 million for the company.

Labelling the revised bid 'unattractive' Resource Pacific managing director Paul Jury said shareholders will be advised on the actions to take by the company shortly.

"The board will evaluate this revised bid in detail when we receive the bidder's statement and will make a formal recommendation to our shareholders in due course," Jury said.

"Resource Pacific's Newpac mine is a high quality asset and the company is well positioned for continued strong growth, capitalising on the current and forecast high coal prices and on our strong customer relationships."

Jury said the company's targeted increase in run-of-mine production to 8 million tonnes per annum is planned to coincide with an expected increase in port capacity in 2010, providing significant revenue growth and cash generation.

"It seems that New Hope wants to capture the potential upside of the Newpac mine for itself, depriving Resource Pacific shareholders of the full benefit of their investment in its development," he said.
