I think we can safely say that we don't know how much is in the ground, but we do know that there is enough of a deposit at a grade that is worth pursuing.  The SP won't likely go through the roof anytime soon but over time, whatever span that might be, this company is likely to do very well.  I think that's as good as it gets for the time being.  Any surprises in the near term I think will be gravy, aside from the instability of the SP.
