RE: An alternative mineralogical model for gold at Clogau5 May 2026 17:48
Copilot AI digested some of the salient information provided in the RNS that’s been quoted in the chat here and states:
“Geologists at Clogau are starting to think that gold might not only occur as “free gold” inside quartz veins (the traditional model), but may also be locked inside sulphide minerals that were blasted during mining.
Because of that, they’re now running tests to understand:
Which sulphide minerals are present (e.g., pyrite, arsenopyrite, galena, etc.)
Whether those sulphides contain gold
How the gold is hosted (coarse particles, microscopic inclusions, chemically bound, etc.)
What processing method would best extract that gold (e.g., flotation, roasting, fine grinding, chemical leaching)
Why this matters
If gold is locked inside sulphides rather than occurring as visible free gold:
The deposit may be richer than previously thought, because sulphide‑hosted gold can be significant.
Different processing techniques would be needed, since free gold is easy to recover, but sulphide‑hosted gold often requires more complex metallurgy.
It could change the economic model of the mine if sulphide material becomes a viable ore source.
In plain English
They’re saying:
“We might have been missing some of the gold. It may be hidden inside sulphide minerals, not just in quartz veins. We’re now testing the sulphides to see how much gold they contain and how to extract it.”
