Correct me if I'm wrong, but based on table, annual revenue after costs before tax is something like $225 million per annum.
costs 473/ton
price 1301/ton
yield 250kt/year
= ~$225 mil annual
They also state 212m tons reserves
That's about $170billion over the life..
These figures are rough but even if they're out by a factor of 10... WOW!
