If the 13% royalty is held by Bruner - then I would be somewhat surprised as this is potentially a massive windfall for whoever holds this royalty. This would also have raised some serious red flags for the two major holders of Falcon - Burlingame and the Russians who would have to have signed off on the Beetaloo deal with SweetPea/Petrohunter. On top of releasing Bruner's Petrohunter from repaying a large chunk of cash and stepping away from Petrohunters property in Colorado, I don't think either of the two major shareholders would have accepted a bonus of 13% royalty to Bruner, but I am not sure.
I wonder whether the royalty would go all the way back to the original company that drilled in the Beetaloo back in the 90's? Either way - it is a significant enough royalty that I am sure Hess had to look a lot harder at the whole program before committing to the seismic, which tells us that the resource potential is probably as big as Ben Law was referring to!!
