RE: AI DISECTING GEOPHYSICIST'S STATEMENT - 25 April RNS15 Oct 2025 07:38
Havieron is an intrusion-related gold-copper system, with mineralisation hosted in breccia, vein, and massive sulphide replacements.
The mineralisation is hosted in metasedimentary rocks (meta-sandstones, meta-siltstones, meta-carbonate) and intrusive rocks, with alteration (amphibole, carbonate, biotite, sericite, chlorite) in wall rocks.
The core sampling and drilling protocol: PQ / HQ / NQ coring in basement, cut halves, typical interval sampling of 0.2–1.0 m (or breaks), oriented cores, geotechnical/logging, high-resolution photography, etc.
The geometry: a breccia pipe (650 m × 350 m footprint, ~1,400 m vertical extent) with a high grade crescent zone on margins, and relatively steep dips in the core zones.
The sulphide assemblage: notably pyrrhotite + chalcopyrite + pyrite in breccia and vein infill, with massive sulphide lenses in some zones.
So when we say “Havieron style cores,” we are looking for brecciation + sulphide veining + alteration + structural setting consistent with an intrusion-related system.
What is known about Red Setter cores / intercepts
Red Setter is adjacent (or near) the same Paterson Province region, and is being cast by Wishbone Gold as a potential analogue to Havieron / Telfer zone.
In one press release, core samples show zones of quartz-carbonate veining and chalcopyrite + pyrite sulphides starting from ~520 m depth, intensifying around 570 m.
They report >130 m of breccia intersected (from ~570 m downwards) with variable brecciation intensity and sulphide content.
In the second hole (step out 200 m), similar brecciation + alteration + sulphide mineralisation was observed, with more intense heat alteration (bleaching) of rock.
Historically (in earlier drilling) Red Setter has returned assays of gold up to 6.4 g/t Au and copper >2.27% in some core intervals, along with widespread hydrothermal alteration (quartz-carbonate sulphide veins) in various lithologies, with breccia textures.
In the 2022 RNS, the company described "quartz-carbonate-sulphide veins … in all lithology types, often with breccia textures" and the presence of pyrite, chalcopyrite, some minor pyrrhotite and bornite, and arsenopyrite.
In more recent updates, the core is being processed and assayed (cutting, sample prep, transport to ALS Labs in Perth) for definitive geochemical comparisons.
Thus, the observed Red Setter cores show breccia structures, veining, and sulphide mineralisation — key hallmarks of the Havieron style.
