RE: Probe at $2.18? LT GoldBull....Great Post, I like your math ....but prefer to simplify via the Danny Dreadlock method. A purchaser of PRB say.........Agnico Eagle................... will look into the different grades and plot that versus the ability to mine those grades. I am with you....PRB is tremendously undervalued...warrants coming up to add to the large cash position(and unfortunately outstanding shares). I hope Super Dave finds more gold along strike but in different areas. New drilling will expand the 10 gm over 50 metres ...got extra drills....just a matter of time...patience and perseverance will pay off this time. We still have very few outstanding shares versus others...also PRB has a lot more gold. Patience my friends it will be worth it.
