Here is a peer I've compared ASN to (not on any detail though) .
Their OPEX is ~$3.300 for 12ktpa.
ASN could be lower .
Capex I estimate to be around ~$350 mill.. by comparing the two from what we have already and they don't.... in saying that they need a shit tonne of extraction and reinjections wells were as ASN GR has 1 extraction well and possibly 3 UIC wells..
