Mr Ryall said Solid Energy's debt stood at $389 million and its interim result, which is due shortly, will show additional losses.
"The new chair and board are focusing on a return to a core coal business which is viable at current world prices. The public is aware that there had already been restructuring at the company, but more may be required," says Mr Ryall.
"The Government appreciates this is a very unsettling time for employees and suppliers and the company's wider stakeholders but it is a process which must be worked through carefully and properly," the ministers say.
Solid's chairman, Mark Ford, said a restructuring and turnaround plan for the company was being prepared by the newly appointed board.
"Despite some modest recovery of international coal prices from a low of around US$140 per tonne in September last year - down from US$224 in June 2012 and a high of US$350 in January 2011 - the company expects any sustained recovery will be prolonged," he said.
