This is based on pricing assumption ranged $90 USD - $110 USD.
So - making lots of assumptions - we earn:
$20 mill if the ore sells for $90 USD p/t.
$75 mill if the ore sells for $110 USD p/t.
Assuming the royalty to price remains fairly consistent when prices are higher, the earnings could be $130 mill p/a at $130 USD p/t.
The iron ore contract price is a bit higher than $130 USD at the moment so I don't think it's insane to project those type of numbers although best to assume the lower numbers and be pleasantly surprised by any upside.
