If this zone (the first of success) just produces at the intial result then thats $US2M in gross revenue a year. Assuming the other 5 zones do no more than match that then thats $US12M all up for VIL. Lets say a net cashflow of $US11M just for arguments sakes.
Take off your current company operating expenses for the company, add some shares for another raising (obviously at a high price given that you are raising funds to connect up to infrastructure and you would be doing that unless you had a sucesful well etc) and apply normal industry PE's.
We'll use 15x but thats without bothing to look them up. It will be around that mark anyway.
I'd suggest that current market cap will greatly increased on the back of a commercial well.
