I agree on proofing although I'm not certain what you mean by revenues being dwarfed by expenditure? Are you referring to the Opex of $167/t that was stated on here as a mistake the day the DFS was released?

If so I've done some numbers below:

Total LOM revenues ~ $27B

Vanadium - 17,560tpa x ~$22,000 x 17 yrs
Titanium - 236,000tpa x ~$4,000 x 17 yrs
Pig iron - 637,000tpa x ~ $400 x 17 yrs

Total LOM expenditure @ $167/t mined ~ $15B

3Mtpa x $167 x 4 yrs
6Mtpa x $167 x 13 years

Operational cash flow stated as $13.6B Lom or ~ $800m per yr

Net cash flow stated as $11.6B or $680m per year

Numbers above align with the stated ranges give or take margin for error in pricing.
