I don't think there is any doubt the magenta applies to more concentrated deposits, at the outer edges of the outcropping. That's always been the case.

As I've said earlier, room and pillar is much cheaper than deeper mining.
Also those faults might not be as significant on the eastern side, the depths don't seem to be that divergent in the cross sections.
There is a significant fault that separates east and west though, that's clear. But the mineralisation at the outer end of the western zone was high. If we get continuity that will be very nice indeed depending on the mining method used but that's getting well ahead.

You're seriously doing a great job with the maps!
