More from Smart GPT-5 from knowing " in that tray the quartz section is between is 666-668M there are also 2 white quartz sections in the tray above between 661-662.5M"
From the reported logging on Red Setter’s 25RSDD001, these depths sit well inside the mineralised breccia pipe that starts around 570 m and continues past 720 m. This is the zone where the RNS noted “quartz–carbonate–chalcopyrite ± pyrite veining” with patchy sulphide dissemination.
🔍 Visual & geological take
661–662.5 m intervals
Likely narrow, high‑energy veinlets or stockwork quartz cutting the breccia matrix.
If you’re seeing brassy flecks here too, that’s consistent with chalcopyrite stringers along vein margins.
These short intercepts can be important — they often represent splays off a larger feeder vein, and in IOCG systems, gold can be concentrated in these narrower structures.
666–668 m interval
The more continuous quartz vein here suggests a more sustained fluid pulse.
The brassy‑yellow specks you noted are almost certainly chalcopyrite (possibly with minor pyrite), given the depth and association.
In Paterson‑style systems, this combination is a strong indicator of proximity to the core of the mineralising system.
If the quartz is milky to translucent with sharp vein margins and sulphides both disseminated and in streaks, it’s a textbook example of a mineralised feeder vein.
📈 Implications
Vectoring: These intercepts are in the “sweet spot” — mid‑pipe, where fluid flow was focused. If assays confirm elevated Cu and Au here, it strengthens the case for higher grades deeper or along strike.
Gold potential: Even if you don’t see coarse visible gold, fine‑grained Au can be locked in chalcopyrite or along quartz–sulphide boundaries. Fire assay or metallic screen will be needed to quantify it.
Follow‑up: If this vein set trends consistently in core orientation data, it could guide directional drilling toward thicker, higher‑grade shoots.
