Yeah a simple calculation using your $5K/acre
330,000 net acres * $5000/acre = 1,650,000,000
1,650,000,000/220,000,000M O/S = $7.50 per share
Then add another $1 for other property and cash, and you'd be looking at $8.50. The key to get that valuation is drilling and then the final go ahead from the government with regulations etc.
Will take some times but worth it in the end.
