This question is primarily for Bart, but I'm interested in whether anyone else might know too. In one of the threads on this site (can't remember which), Bart mentions that Maurice Celis says that, at the current level being mined, it looks as if some of the layers are merging into one another. I'm curious about the order the layers are found. Anyone know? I ask because sometimes I see stones that really do look like they're from two layers.
