Only two issues with the delays are the speed they can bring new projects online and the need to pay back debt. Nothing urgent at the moment.

Other research I have done to try and work out current profitability
Iluka Catby mine unit cost of production from 2020 - 2022 rose by 33%
STA basket price sold in 7th shipment is 33% above forecast for DFS so the numbers should still be relevant as is.
Revenue over double costs based of DFS therefore even at 50% capacity the project is likely to be profitable.
STA price for Chloride Ilmenite in DFS (which is locked in for 5 yrs) $260-$280 US per tonne, current price $400 therefore lots of upside once the 5 yrs is finished or capacity increases.
Baltic shipping prices now at pre covid levels, this implies that finding ships to carry product should only be a short term issue.
