Ann: Wallbrook Exploration Target & Mineral Resource Estimate, page-104

G'day Robbo,

"Are you suggesting NXM should have lowered the standard of its inferred resource and lowered the credibility of its JORC to imagine a 200m deep pit?"

No, but I'd like to see the pit designs that contributed to the MRE set out something like below.





If the pits are either blue or yellow, an investor can clearly see that higher drill density will capture an increase in MRE ozs.

If the pits are orange then further infil drilling will increase the MRE category, but will probably yield a minimal increase in MRE ozs.
