Jim Tilsley. This guy signs off on news releases and if it's not up to his standards, it's not going to market.

I think we can be certain that we won't be knowing what's in the ground until JT is confident he understands it first.

Good news here is that the guys brain is so complex, even if he did leak information (which would not happen in 100 years) 99.99% of the population wouldn't understand what he was talking about anyways.
