According to DFS, the project NPV after-tax with 7.5% discount, using a $6,000/t LC price, and a 60%/40% debt/equity, on 16.4kt/pa production was

$449 million

Since then, the LC price has climbed to $7,000/t, the debt/equity has been signed off at 70%/30%, production now expected to be 17.5kt/pa on account of better grades, yields and flow rates on most recent production testing. These all have a positive effect on the project NPV.
