A site visit is not a formality to satisfy a checklist. Done properly, it is the single richest source of evidence in a verification, because unlike documents, a working site is difficult to fully stage — and the parts that are staged tend to leave visible seams once you know where to look.
Stockpile volume against claimed history is the first and most direct check. A seller claiming eighteen months of continuous production should have a stockpile, tailings profile, and waste-rock footprint consistent with that timeline. A pile that looks freshly built, sitting on ground with no compaction or weathering pattern beneath it, does not match a claimed history of sustained output — regardless of what the production records say. Conversely, genuine long-run operations tend to show layering: visible strata in the stockpile from different production runs, weather-differentiated surfaces, and a footprint that has clearly grown over time rather than appeared at once.
Weathering and oxidation tell a similar story at the mineral level. Freshly broken rock and long-exposed rock behave differently — oxidation rims, colour change, and surface texture develop at a roughly known rate. Material presented as having been mined months ago that shows none of this is a signal worth pursuing, not dismissing as a minor inconsistency.
Equipment condition is the second major indicator. Claimed throughput has physical consequences: wear patterns on crushing and processing equipment, fuel and consumables usage, and the condition of haul roads all scale with actual production volume. A site with pristine equipment and an untouched haul road claiming years of commercial-scale output is telling you something, and it is not what the production figures say.
The third indicator is harder to fake than any document: operational tempo. A functioning mine has a rhythm — shift changes, a workforce that behaves like people who do this every day rather than people assembled for a visit, logistics vehicles moving on a schedule that makes sense against the claimed output, and support infrastructure — power, water, fuel storage — sized appropriately for the operation described. An unannounced or partially unannounced visit component, where feasible and safe, is one of the more effective ways to see this tempo rather than a version of it staged for a scheduled inspection.
None of these checks require specialist geological training to apply usefully — they require a structured protocol, a trained eye, and a comparison against what the seller has actually claimed. That comparison, more than any single observation, is where a site visit either confirms a transaction or ends one.
