Tag Oil was such a much easier call at $2.50 a share since they had a pile of cash, debt free and started with intial shallow targets and then built from there. Tag will soon be running at annualized + or - $200 million top line revenue. I see Tag at $20 or more within 12 months unless huge drop in oil prices.
NZERF has greater risk and I assume will need to raise funds, but there certainly is some potential great upside if they hit another significant well in their current drilling. My guess would be $5-$7 potential upside in 12 - 18 months but could be wrong because it is so early in the game.
