I didn't suggest that geologists couldn't discern the difference between pyrite and chalco. ICG's announcement to the ASX dated 7 April, 2022 [Page 2] did: "Copper levels towards the bottom of the hole are below that which might be anticipated from the Government logging and reports of visible mineralisation. This may be attributed to the difficulties of discerning chalcopyrite, bornite and pyrite." ICG is not the speculative investment for me because I can't confidently rely on what is disseminated (including per below). There's no use me posting anymore as there's too much positive bias on these threads and a lack of objectivity/inquisitiveness to challenge the status quo on genuine issues. Best of luck on your journey!

ICG's Announcement to ASX dated 21 March, 2021:

"Copper mineralisation, (chalcopyrite and bornite), increases from 250m depth and is open at EOH."

"The recent high-resolution core photography further reveals the widespread nature of alteration, structural deformation, veining, haematite and sulphides in drill hole NDIBK04. The company notes several zones of increased visible copper sulphide mineralisation that occur over broad intervals of NDIBK04 that include:

• 244.29m – 251.95m: Down-hole interval of 7.66m with varying pyrite-chalcopyrite-pyrrhotite-arsenopyrite content occurring as disseminations and vein selvages that includes a 2.3m interval of 20% pyrite + 8% chalcopyrite + 2% pyrrhotite (by volume) from 249.65m depth (see core photo in Figure 1 and selected core tray photos in Figure 2).
• 329.34 – 363.40m: Down-hole interval of 34.06m with increased pyrite-pyrrhotite as vein selvages to pervasive in nature, with spotty occurrences of chalcopyrite and bornite as vein selvages and disseminations (see selected core tray photos in Figure 3).
• 411.80 – 416.30m (EOH): Down-hole interval of 4.39m (open ended) with quartz veining with increased pyrrhotite-chalcopyrite-bornite that includes the final 2.18m of the hole logged with 4% chalcopyrite, estimated by volume (see selected core tray photos in Figure 4).

No assay data is currently available. The company will release the government assay data as soon as it is available. The occurrence of hydrothermal alteration and sulphides, especially ore-forming copper sulphides, over a 326.8m down-hole interval in NDIBK04, is very encouraging. Importantly, the visually government-logged copper mineralisation remains strong at EOH, meaning the mineralisation as it is currently understood is open in all directions. It is also most encouraging seeing bornite in the core and noting that its abundance appears to increase with depth. Bornite is a high-grade copper sulphide and generally forms in the hotter parts of a mineralised system and towards where one would expect to find potential higher grade ore."

"While work continues on data interpretation and drill targeting studies at the greater Frewena Project, the company looks forward to the opportunity to inspect the East Tennant stratigraphic drill core at the upcoming AGES Seminar in Alice Springs, to be held 19-22 April, and to obtaining further information updates and advice from the GA/NTGS staff who will be attending."

ICG's Announcement to ASX dated 22 April, 2021:
[Page 1]
"With respect to NDI drill-hole NDIBK04 (as previously reported to the market), it contains a significant interval of alteration and mineralisation, including percentage levels of the copper ore-forming minerals chalcopyrite and bornite."
[Page 2]
"Inca’s Managing Director, Mr Ross Brown, said: “...At the time of finalising this announcement, we were viewing the core from hole NDIBK04 in the core shed, and we are immediately impressed by the broad occurrences of sulphides in the hole, including chalcopyrite, bornite, sphalerite, pyrite and arsenopyrite. Sulphides occur as disseminations, veinlets and veins and reflect multiple phases of mineralisation. Within the broad envelope of sulphide mineralisation, there are local zones with between 5% and 15% sulphide by rock volume. A photo of the core taken this morning is provided in Figure 2 below.”"

"Necessarily brief visual logging conducted by the Company confirmed the occurrence of percentage levels of the copper ore-forming minerals chalcopyrite and bornite in zones within a broad intersection of sulphide mineralisation in NDIBK04."
[Page 2]
"Inca’s Managing Director, Mr Ross Brown, said: “...Our review of the core from hole NDIBK04 immediately impressed us with broad occurrences of sulphides in the hole. As well as the visible copper minerals, we’ve seen sphalerite – a zinc mineral, and arsenopyrite. Gold is not unusually associated with arsenopyrite mineralisation. Within the broad envelope of sulphide mineralisation, there are local zones with between 5% and 15% sulphide by rock volume.""
