No need complicate the capex figure, you can covert to per mtpa's capex as below

	Column 1	Column 2	Column 3	Column 4	Column 5	Column 6
0	Item	CLQ （PFS）Laterite	ARL (PFS)Laterite	BAR/CNJ (SS)laterite，oxidized	AML (SS)Sulphide	NZC( Stage 1 DMS)Sulphide
1	Throughput （Mtpa)	2.5 Mtpa	1Mtpa (&1.5Mt)	1.5Mtpapa	2.5 Mt	1 Mt
2	CAPEX	US$784m	US$472m	US$156.9m	US$484M	US$ 53.12m
3	Per mtpa's Capex ( million US$)	313.60	472.00	104.60	193.60	53.12

for C1 cost, I think you can refer to Sherritt's actual production stage data, for your reference, Sherritt is famous for lowest C1 cash cost and same as laterite, 2017 avg. C1 Cash Costs US$4.72/lb , ARL maybe do better than that in coming revised to 2.5mtpa.
