Last month, the company announced plans to sell power projects for $825m to repay some of its debts. These debts have forced the company to avoid paying wages to around 380 staff at the mine, leading to disruptions, reported ABC.
Australia member for Collie-Preston Mick Murray told the news agency that: "One of the problems is the price of coal, its just not high enough to sustain the mine.
"You know with overheads…the losses continue so it’s quite obvious now it’s just they’ve decided to cut their losses and put it on the market."
The company has however noted that discussions are in preliminary stages.
"The government should have been in there a long time ago mediating and working out how we can have a sustainable mine of the future," Murray added.
"The sale won’t make the mine sustainable. The cost of production is still higher than the coal price they are getting so it doesn’t matter who buys it, something has to change."
Lanco, which purchased Griffin in 2011 for $760m, plans to push its annual mining production by four times to around 18 million tonnes by 2018.
