Hmm lets see...
"Rough guess is that EV/Reserve value for average quality coal resource is at least $5/t, and potentially up to $15/t
"
400Mt x $5 = $2Bil Is that right??
OR
400Mt x $15 = $6Bil ?
$6Bil resource with a market cap of 18Mil?
I know that cant be right, but I'm hopeless with that stuff and keen to learn.
