Maybe useful to someone. I've got a GPT chat open where I've been quite conservative and kept to facts.
==========================
Why “Sulphide Mineralisation” Is a Big Deal in This Context
Sulphides = metal hosts
Most gold and copper systems in intrusive domes occur with sulphides (e.g., pyrite, chalcopyrite, bornite, arsenopyrite). Seeing them is a first-tier vectoring clue.
In MT data, conductive zones = possible sulphides
If the mobile MT survey suggested a 3 km strike conductive body, and they’re now intersecting visible sulphides within it, that strengthens the interpretation that the geophysics mapped mineralisation rather than just graphitic shales or saline water.
2️⃣ Probability Shift
Before hitting visible sulphides:
The model was: “We think there’s mineralisation under this dome based on geophysics and surface samples.”
Probability of meaningful intercept: maybe 25–35% in a first-pass hole.
After visible sulphides in core:
The model becomes: “We are physically in the mineralised system — now we need to see grade & continuity.”
Probability of a viable resource jumps — not to certainty, but potentially 50–60% in terms of hitting economic-grade intervals somewhere along the structure.
=======================
So the market is pricing a 50% chance of... what, a 100m, 200m, 500m mcap? At 10m... I'll have a bit of that. :)
