It has significantly increased the amount of debts it is claiming after Bendigo mining company Kralcopic went into voluntary administration last month.

The government is now claiming $10,437,150, according to documents filed with the Australian Securities and Investment Commission.

The figure is more than 11 times what the government had originally asked for.

The change has dramatically affected discussions about what to do with Kralcopic, which once held mining rights to sites across Bendigo before collapsing.

A number of companies including Kralcopic's former owner GBM Gold have been involved in discussions about whether to liquidate the company or form a new deed of company arrangement.

The government's mining regulator Earth Resources Regulation has also been involved as it is still owed money and is keen to see Bendigo's sites rehabilitated.

The Advertiser previously reported that it had sighted documents suggesting the government warned administrators they would "significantly" raise the figure they were claiming ahead of a creditors' meeting that was supposed to take place this week.

That document mentioned a $918,000 proof of debt.

That figure included claims for a number of debts, including site monitoring and maintenance, site rehabilitation works, money for environmental works, outstanding regulatory fees and legal costs.

The revised figure was one of four reasons that administrators postponed a meeting with creditors that was supposed to take place on Thursday with less than 24 hours notice.

Another was connected to a dispute still to play out in the Supreme Court over the status of mining assets at a site in Kangaroo Flat.

The government and GBM Gold have been seeking a ruling about a huge gold processing plant that could be worth millions of dollars.

The Advertiser is yet to establish whether the government's revision of debts is connected to the processing plant or another factor.

But GBM Gold is understood to have filed paperwork this week with the Supreme Court about the processing plant.

It has also drafted a proposed deed of company arrangement that it would have presented to creditors last Thursday, had the meeting not been postponed.

Sources familiar with Kralcopic's history say that when the company lost its mining licences it had six months to deal with any equipment on site.

If it did not, the equipment would default to the government.

The Advertiser understands the gold plant could be the most valuable asset Kralcopic still has.

A decision on it would could influence how much money creditors could reclaim.

Earth Resources Regulation this week issued a community bulletin noting it officially took over crown land at the site.

"We are seeking further orders from the Supreme Court on this issue before making any on-site changes," the bulletin stated.

The bulletin did not outline details about the case or the debt that the government is chasing.

Earth Resources Regulation has been contacted about its revised figure.

GBM Gold has also been contacted.
