Shouldn't there be a discount of probable resource to recoverable NG, say 50%, also a discount of say 75% to gas price. They have no infrastructure of producing wells so the buyer would just be buying gas in the ground. So 7T cubic feet at 25% mrkt price for NG; say $1/1000 cubic ft for gas in the ground would be 7 billion dollars divided by 100Million shares = $70 per share.
Have subsequently read geopressures post that 30% is more probable then 50% so reducing the above by 20% = 2.1T cubic feet
