Pardon the ignorance here but after the BFS drops and then the reRE, will we simply be able to plug the new RE number into the existing BFS calculations and get a new cost to get the goods out of the ground?

Not that easy, they will need a new mine plan. At this point it's Feasibility and then RE2 and that's it.

We have enough data and proof, All the big players will already know the scope of this without having to keep upgrading it.
