Start deducting some realities.
$8.6m royalties owed to mining contractor.
You only ask for weekly payments when you are scared of a companies solvency

A contractor onsite would know more than you or me.

Stockpiles of uneconomic ore are uneconomic to mill.
unless it's 1g/ton and you can pump over 7000 tons a day through the plant every day nonstop it's not making money.
You can't mill it if you haven't done the tailings lift $6m.
nor would you payoff staff to recruit them again just for a toll milling deal that wasn't for at least 5yrs at the mills economic capacity.

Maybe the mining contractor has site sown up with life of mine mining contract like AMI has with their Dargues dog mine.......no mining without them.

Thats the research I would do which is one of many reasons why I quit AMI over Dargues and would have done the same with GCY if it was the case..

Best of luck with your calcs.

I would imagine any buyer would also want that royalty sorted.
