this is shaping up to be quite a find.
i really like the structural position of 'a zone', though the interp of 'c zone' looks a little hopeful to me, though i only have public info to go on.
as well as the proposed dd hole to the west of hole 51, how about another to the east rob? it looks like a significant depletion zone and supergene blanket at the top, so chasing the depletion at depth could be very rewarding.
looking forward to the dd hole, and some core photos.
