PricewaterhouseCoopers receiver John Fisk said the worst-case scenario was closing the mine, according to the New Zealand Herald.

The coal company reportedly has $NZ10 million ($A7.73 million) of remaining cash.

Fisk told NewstalkZB he aimed to get the “best price obtainable for the assets”

Recovery teams at the mine recently sealed up cracks around the slimline shaft, making it easier to inert the mine with the GAG jet engine.

The New Zealand Herald also reported that the mine entrance was sealed yesterday.

ILN is yet to get confirmation this took place.

PwC released a statement this morning:

“As receivers, our principal role is to achieve the financial returns for the company’s secured lenders,” Fisk said.

“However, in the case of Pike River Coal Limited, we are very aware of the extenuating circumstances surrounding not only the company but also the families and the West Coast community, and the implications of the company’s receivership on all parties.

“We wish to see the mine atmosphere stabilised and inert with risk of underground fires or further explosions eliminated.

“The current Police-led operation has not yet been able to achieve this, therefore we need to consider alternative options.

“One option is to temporarily seal the mine whilst other longer-term options are properly evaluated.”
