what is so good about this stock, page-18

Evening E and All,
Correct me if I am wrong, but the ball park figures I've arrived at over the past 3 years I've been in and out of PNA are as follows.
Assuming present metal and input prices,
1. Phu Kham:2.4billion profit on 10 year minelife
2. Ben Houyxai:300 million over 6 year minelife[assumes profit of $500 per ounce of gold and 8 dollars per ounce of silver]
3. Puthep: 1.8 billion profit over 16 years[assuming PNA moves to 60% ownership and similar margins to Phu Kham]

These sorts of figures support SP of about 40c?

Question then remains, how much valuation do you put on their exploration acreage ,their management expertise, and potential for brownfield expansion?
10c? 15c?
All figures above ,move with metal price and input cost changes.
Happy to be shot down in flames if I've got it wrong.
But anyone doing so, please use figures in your ammunition.
cheers
