I posted this on the Yahoo! board a couple weeks ago (Gold was $975/ounce).  I believe it gives us a starting point to begin discussions:

"Okay - so let's see, I went back to check the facts... 20,761,000 measured and indicated ounces (at $550/ounce - might be significantly higher at $1,000/ounce), "The average total cash operating costs (including revenue-based royalties) are now estimated at $339 per ounce over the life of the mine and $244 per ounce during the first five years."
261,700,000 shares outstanding.

If I take $975/ounce and subtract $339/ounce, I get a balance of $636/ounce multiplied by 20,761,000= $13,203,996,000/261,700,00 = $50.45/share. If we give a generous 25% Venezuela discount you still have $37.84/ounce notwithstanding additional resources and higher future gold prices. If this thing is below $18-$20 (admittedly very conservative) post permit then we better hold on for a tremendous buy-out offer!!"
