Ann: Further Significant High-grade Au Intersections at Calibre, page-24

Yes the results are consistent. Always prefer higher but that's what Calibre seems to be. A few higher grade areas that may be included in a starter pit plus large volumes of bulk with patchy higher grades that become the bread and butter of a long lived possible mine.


There are two groups of people in the Citadel and Winu areas. Two sets of negotiations?

Both areas have lots of sand dunes which, possibly not as culturally significant as the caves, are none the less important.

AZY and Rio (plus all exploration companies?) are aware of the environmental as well as cultural significance of them. A lot of care is shown in how drill sites are accessed to avoid disturbance. Rio, IMO, have chosen not to drill certain potentially interesting NW extensions at Winu for this reason.


A lot of drilling has been done since this always with a buffer zone near sand dune areas.

A major issue that may need to be addressed at some future date if not sooner.

===========================
Shines2 - 2021 drill program 11-14 Kms at Citadel. Drill programs are made to be changed as results and circumstances dictate. Never a good idea to assign hole numbers before they are drilled as the egg on face and problems it can cause are sometimes outstanding.

Looking at the image of Winu drilling from mid 2020 shows how much can be done and still leave the resource at inferred to indicated. By comparison Calibre is relatively lightly drilled such that another 5-6 Kms may only close up the gaps and margins to 300m or so. No real idea just putting out some 'gut feel' numbers.

The various drill programs have closed the spacing to something less than 100m but 50x50 or near double the amount already drilled could be needed to take it beyond scoping to pfs?? again no real idea.

Early grid 11000N-12350N with most lines 100m apart. Drill density looks quite high but may need to be increased to satisfy confidence levels.
