Ann: Quarterly Cashflow Report, page-22

Regarding a cash shortfall,
They used 51 million in June 2020 Q, 47mil in Sep Q and 42mil in December Q.

They are 96% done on their gas and power facilities. They are 86% done on ponds. And they 71% done on SOP plant.

So costs for gas and power will have almost finished, after being included in operating expenses over these past 3 updates.
Costs for ponds would have just 1Q left, maybe less (after being included for many many quarters in operating expenses).
And the SOP plant construction has been included for ages (couldn't tell you how constant that is though) but I'd say that'd make up the majority of their future expenses.

Also keep in mind that their last shipment of equipment for the plant was sent out a few months ago (unsure which quarter it was) but I find it unlikely that they would pay for that in full in the next upcoming 2 quarters. And the cash outflows are downtrending as work on storage, warehouses, offices, lodging etc is all completed.
