That of course is the problem, and I don't have an answer. It's probably not possible to know the "correct" value without knowing how much of the particular material there is out there, and that is something we don't for just about everything. And even if we know the amount there is, you still can't put a dollar value on it, the pricing would be done by the market. But the market would do a better job if we knew how much there is.
