From the quarterly:

"However, the environmental pressure on miners, including those that form part of their supply chain for alumina refining reagents, has led to a significant and unexpected increase in Caustic Soda prices; a key reagent in alumina refineries. This will potentially impact sales prices for higher silica bauxites, such as that produced at Bauxite Hills".

In other words, prices received are likely to be lower for the 50% of MMI annual production that isn't commited.

And unless shipments are prepaid, I don't know whether they are or not, the loading of ore onto a ship does not result in cash flow. In which case cash may not be received until delivered, and possibly later depending on the commercial terms of the agreement. In the absence of more information, we don't know what cash inflows will be for the current quarter and whether they will be sufficient to cover outflows.

That's my take on it, DYOR.
