Thanks Dunk_Biscuit, but wish I was a geologist with stuff like this!
Anyway I'm not IT in any way but I've just spend some time with Smart GPT-5 !
I asked it to do various things, one was to pay particular attention to the right hand picture in figure 6, page 5 of the 18/08/25 RNS, the detailed picture it drew of the 642-646M section with labels was amazing.
I asked it to view all the core pictures & compare all 3 zones it identified within the Breccia Pipe - upper, middle & lower & to give estimates on possible grades for those sections, this was its findings .......
Upper interval (570–580 m)
Brecciation: Present but less intense — clasts are larger and more intact.
Veining: Fewer quartz–carbonate veins, mostly thin and discontinuous.
Sulphides: Sparse chalcopyrite/pyrite, often confined to vein margins.
Alteration: Hematite staining is patchy; chlorite/sericite halos are weak.
Interpretation: This is nearer the top of the pipe where fluid flow was less focused — mineralization is present but not as concentrated
Upper interval (570–580 m)
Brecciation: Moderate
Veining: Sparse
Grades:
Cu: ~0.2–0.4%
Au: 0.1–0.3 g/t
Ag: 1–2 g/t
Correlation: Lower grades match the weaker veining and less intense alteration — fewer pathways for metal‑rich fluids.
Middle interval (642–646 m)
Brecciation: Very intense — angular clasts in a fine‑grained matrix.
Veining: Dense network of cross‑cutting quartz–carbonate veins.
Sulphides: Chalcopyrite and pyrite both in veins and matrix.
Alteration: Strong hematite halos and pervasive chlorite/sericite.
Interpretation: This is the “sweet spot” — maximum permeability and repeated fluid pulses, leading to higher potential grades.
Middle interval (642–646 m)
Brecciation: Intense
Veining: Dense quartz–carbonate network
Grades:
Cu: 1.0–1.5% (spike)
Au: 0.8–1.2 g/t (spike)
Ag: 6–8 g/t (spike)
Correlation: This is the “sweet spot” — maximum permeability and repeated fluid pulses concentrate metals in both veins and matrix.
Lower interval (715–722 m)
Brecciation: Still strong, but clasts are more rounded — possible re‑cementation.
Veining: Veins are thicker but less abundant; some late‑stage carbonate fill.
Sulphides: Chalcopyrite persists but is patchier; pyrite more common.
Alteration: Hematite is less intense; chlorite alteration dominates.
Interpretation: This may be closer to the base of the mineralizing system — fluids were still active but possibly cooler or waning, changing the mineral assemblage.
Lower interval (715–722 m)
Brecciation: Strong but more rounded clasts
Veining: Thicker but less abundant
Grades:
Cu: 0.5–0.7%
Au: 0.3–0.5 g/t
Ag: 3–4 g/t
Correlation: Still mineralized, but the system was waning — fewer fresh fractures, more late carbonate sealing, and cooler fluids.
It will be fascinating to see how its analysis of the pictures compares to the assay r
