@Hiddenvalue, I reckon the $100m cash injection required is pretty obvious from the CR indicative (minimum subscription) pro forma balance sheet.
$70 million to square off trade payables (because who would feel motivated to do any work for WMC if they don't pay accounts in full).
$30 million into Mercuria's bread basket (to drastically reduce loan repayment obligations & also keep Mercuria happy so they'll feel less inclined to call in the Receivers for a fire sale).

There's your $100m
$100m cash injection from stakeholders might then suggest $60m - $70m left in the company coffers to reset the mine plan (during these increasingly difficult times) & provide another roll of the dice to achieve commercial production of 110k - 120kozpa sometime during CY2023 (maybe).
If you're of the opinion that WMC need less / more than $100m cash injection to rise like the Phoenix, please don't hesitate to post for discussion.
