First, the NPV of $513M applies to the 2012 Feasibility Study, at a discount rate of 8%. If you are going to use such a conservative discount then at least gross it up by a year.

Is 8% not the standard discount rate for a mine prospect with no environmental permits?

Second, we know this NPV was skewed with the 171 MT

We know this but the market does not

Third, if you are not investing for the untapped potential of bigger and better mine economics and additional mine life, you should drop the numbers and sell as soon as the market cap hits $134million.

Why would I sell if I believe there to be short term 20 - 30% upside from here and a long term $1.30 buyout potential?
