What exactly do you think comes out of the ground when they do RC drilling? Because you clearly don't understand the process. The samples piles in RC sampling are sieved and a geo examines the chips to log whats in the interval - thats how they know whats in the pegmatite, and thats what hasn't been reported here, why?.
