This is the way I have been looking atestimates for 2.25mtpa CAPEX, firstly it is clearly stated in the PFS reaching 2.25mtpa from the 1.5mpta train is possible with much of the same equipment just optimisation and reduced residence time meaning in order for the cost to blow out on paper as you have stated both the 1mpta and 1.5mpta PFS would be incorrect.
Secondly I would argue that if you wanted to use anybody as a comp for ARL you can only really use AUZ in Aus as they are using the same tech and same lab Simulus. There are some very qualified engineers over there (EG Flippa) who are all estimating $800-850mUSD for 2mtpa.
CLQ has choosen a different path which is many respects makes them uncomparable now.
Due to the ore at KNP and potentially using a smaller plant for higher throughput I think our CAPEX will come in at or below this level my estimate is $790m USD inc the Sc circut.
I know I have posted this previously though probably relevant again.
