1000 bagger? That would be $200 per share and a market cap of $140B dollars. ERHE would need to be sitting on proven of 10-15 BILLION barrels... not likely in the coming decade, who really knows though. Let's get to $10 first, but I like the way you think!

Best possibilities in EEZ north/northeast of Principe.
Several attempts by more than one IHub poster to get confirmation of figures from ANP went answered, as posted at the time.
