How to Identify Elite Geologists & New Discoveries Others Miss: Insights from Quinton Hennigh

Summary

Hennigh argues years of undercapitalization, permitting delays, lab shortages and too few drillers keep metal supply tight.

He sees gold's pullback from $5,500 toward $4,500 and silver near $70 as new price floors, not a cycle top.

Investors should watch early intercepts of 100 gram-metres (grade times length) — the pattern behind Snowline's Valley discovery.

Elite exploration geologists, in his view, pair mentorship, system-scale thinking, an 80/20 drilling split and metallurgy-first screening.

Bolivia's improved politics and underexplored ground, he says, offer more upside than troubled jurisdictions such as Mexico.

Hennigh credits his time at Newmont for two frameworks he still uses: sending any promising sample to the metallurgists before the exploration team gets excited, and screening early drill intercepts by gram-metres.
The metallurgy rule he picked up there was blunt — if the rock cannot be processed, the deposit is worth nothing — and Newmont's open-pit rule of thumb was roughly 2.58 grams per tonne.
He says a Newmont team calculated gram-metre intercepts from drill-company news releases every morning, and that discoveries showing 100 gram-metre holes in their early holes were the ones that became discoveries.
Newmont's 2002 combination with Normandy and Franco brought Normandy's BLEG stream-sediment technique in-house; he says it was field-tested before the company used it over the Yukon.
He says Newmont missed the large ATAC run on that Yukon ground while quietly surveying in the background, which he uses as an example of a major company not moving in a straight line.

Named only in Hennigh's account of Newmont's 2002 combination with Normandy and Franco, which brought Normandy's BLEG stream-sediment technique into Newmont; he offers no view on Franco-Nevada itself.

Hennigh says Snowline drew no market attention when it drilled a small target he calls Valley, after better results at Jupiter, in late 2021 — until two or three of the first few holes came in above 100 gram-metres in the first pass.
The metallurgical read mattered as much as the intercepts: gold sitting as particles in sheeted veins alongside some bismuth, with no significant sulfide, told him the gold was not locked in sulfides and the deposit should process well.
He says he went in immediately and told colleagues at the fund he advises to pay particular attention, and became more convinced once 2022 drilling showed sheeted veins over hundreds of meters.
He says remoteness in the Yukon did not deter him because he had worked that ground at Newmont, knew access was workable (winter roads and an operating silver mine to the west) and knew the management and First Nations contacts.

Top takeaway His own sharpest observation is that Snowline, which he treats as a genuine discovery, stalled on location — in the middle of nowhere, needing infrastructure — and he raises remoteness and jurisdiction as a filter separate from the geology.
He separates good geologists from elite ones: good ones know their deposit theory, elite ones identify new targets earlier, and he invokes Pareto's law across the sector to explain the split.
He frames the market debate with S&P Global data showing exploration budgets up year over year with gold leading the pack, and asks whether the sector is already saturated with too many companies and bloated valuations.
He calls San Cristobal's education and outreach program a model other companies should copy, citing a conversation a couple of months earlier with a junior's CEO for whom outreach and hiring the best geologists were central strategy.
