Mining discoveries: what investors should ask

"How confident are you, and why?"

Start here. Any credible claim about a deposit comes with a confidence level and the evidence for it. Ask what the model actually says: not "there is copper", but how likely, at what grade, over what volume.

If the answer is a single confident number with no range, be careful. Real subsurface estimates carry uncertainty. A claim that hides it is either naive or selling. Ask to see the distribution, not just the headline.

"Show me the holes"

A prediction means little until it meets a drill bit. Ask what has been tested, what the model got right, and what it got wrong. A method that has been drilled and sometimes missed is more trustworthy than one that has never been checked.

Ask, too, how the model handles being wrong. Does a failed hole update it, or does it carry on asserting the same answer? A model that learns from misses is doing science. One that does not is doing marketing.

"Can I see the working?"

Reporting codes are moving towards traceability for good reason. You should want the same. Ask what data went in, how uncertainty was handled, and who reviewed the result. A specialist-checked answer beats a raw model output every time.

The question behind the questions

All of these ask one thing: is this honest about what it does not know? A discovery story that admits its uncertainty is worth more than one that radiates false confidence.

Back the models, and the teams, that show their odds and their evidence. In exploration, the willingness to be pinned down is the surest sign there is something real to pin.
