Book value for Sage .08 cents---- amt of shares mutiplied by book value equals worth of company----what i don't understand is what is worth of company based on--what they have found in the ground?and i assume that value in the ground would have to assume some extraction cost? or some arbitrary value for their properties/leases? Is this correct? if not--what is? Its all mumbo-jumbo to me-help me clear it up...
