Ann: Administrators Appointed, page-28

I'm starting to get a better idea of what is happening...
CAI called in voluntary administration because they can not pay McMahon ... this protects them for a longer period against having to pay the outstanding.
Macquarie has come in over the top as senior secured creditor with their own appointed administrator to be in control of the situation.
For the time being the mine will continue production... so a revenue stream (which apparently is currently cash flow positive) is maintained.

Some chance this can be worked through... imo. Maybe another rejig of debt?
