This is a post by Midnight from an earlier thread in CMM where this came up.

"In simple terms it's a 3D shell produced by feeding in a bunch of parameters (mining cost assumptions) into a program with algorithms that are driven by the grade and tonnes in the geological resource estimation model. The pit design is defined by the shell so it's what the pit might look like at 1600AUD POG, but importantly it is also used to capture the in-pit JORC resource at the same POG."

As I understand Midnight's description the higher the constraining value of the Pit shell is the larger the pit, and hence resource, would be. The converse would also be true IMO.

Today's announcement appears to confirm a more extensive high grade zone in the footwall which may make deeper mining more feasible especially on section 199775n



This is a suggestion of continuity over some 325 lateral meters between this and the 200100N section.

The results of the recent large drilling program will take some time to be fully digested. The Bibra area seems to have so many stacked lenses especially to the west and south and some to the east it suggests there is a very large gold footprint that has only just begun to be revealed.
