Founder & Host | Mining Stock Education | Engineering-trained interviewer of junior mining geologists, analysts, and executives

"Founder of Mining Stock Education; engineering-trained interviewer who makes junior mining evaluation accessible to everyday investors."

Interviewer

Biography

Brian Leni, P.Eng. (Professional Engineer, a licensed engineering designation in Canada), is the founder and host of Mining Stock Education (MSE), a long-running interview platform and podcast covering junior mining stocks — the small exploration and development companies responsible for most new mineral discoveries. A trained engineer who worked in mineral exploration before launching the platform, Leni is known for interviews that translate geology, financing structures, and market timing into plain terms for non-technical investors.

Leni launched MSE in 2014, and the platform has published hundreds of episodes across multiple metal price cycles. His guests range from fund managers and newsletter analysts to economic geologists and mining company executives. Recent coverage illustrates the range: a conversation with economic geologist Neil Adshead on how he screens early-stage junior companies, and an interview with analyst Nicole Adshead-Bell on copper's rising profile as a critical mineral. Episodes are distributed through the MSE website, podcast feeds, and YouTube.

Leni's engineering background shapes how he runs an interview. He presses guests on the specifics that determine whether a junior survives: drill results, the quality of a resource estimate (a calculation of how much metal a deposit contains and how much confidence the market can place in that number), share structure and dilution, financing requirements, and jurisdiction risk. Through his Field Notes project, he goes beyond hosting — he documents his own evaluation process and investment decisions in story format, giving viewers a worked example of the baseline method for judging a junior mining company.

For investors building their knowledge, Leni's value is educational rather than predictive. Following MSE means hearing experienced evaluators repeatedly weigh geology against share price, capital structure, and management quality — the questions worth asking before buying any junior stock. His coverage currently spans precious metals, copper, and uranium juniors, with ongoing attention to the macroeconomic conditions that drive the sector.

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

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

host Apr 20, 2026
  • 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.

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.

Junior Mining Volatility, Opportunity Cost, Overthink & ‘It’s Cheap Enough’ - Powers & Leni Discuss

Junior Mining Volatility, Opportunity Cost, Overthink & ‘It’s Cheap Enough’ - Powers & Leni Discuss

guest Mar 29, 2026
  • Top takeaway Lenny says he spent more than a year positioning for a market turn — taking profits in gold, rotating into copper, then into a large cash position by early 2026 — so the Middle East conflict-driven 25-35% drawdowns find him comfortable rather than forced to sell.
  • He describes buying one company that fell roughly 35-37% from its peak, entering below where institutions put in about $50 million earlier in the year, citing full funding, near-term catalysts, and boots-on-the-ground diligence; he reports being up about 35% within a week.
  • He argues investors should counter overthinking and fear with a quantitative price-to-value anchor — e.g. a company worth $100 million selling for $20 million — and demand 3-5X differentials before accepting macro coin-flips like the Middle East conflict.
  • He is traveling to Uruguay for a site visit to Sun Valley, a private company expected to go public within 3-4 months, citing its dominant land position in an underexplored organic belt and Uruguay's strong geological potential.
  • He credits mentors for key mental models — including that if the world truly ends it makes no difference whether money sits in a bank or trading account — and says staying calm in the current volatility marks real progress as an investor after tough years in 2022-2023.

Volatility from the Middle East conflict is testing junior mining investors' conviction, and the hosts argue preparation, not prediction, protects portfolios. Sizing positions in advance and holding cash lets investors buy quality names during drawdowns instead of panic-selling at the bottom. A quantitative price-to-value differential — a company worth $100 million selling for $20 million — gives investors the confidence that an idea is 'cheap enough'. Recycling junior mining profits into real assets and cashflow reduces emotional pressure and guards against opportunity cost in life and portfolio. Wins in exploration often come from luck, not skill; the hosts urge investors to take losses honestly and avoid confusing bull markets with brains.

"We're Already in Deficit”: The Critical Minerals Crisis No One's Talking About - Amanda van Dyke

"We're Already in Deficit”: The Critical Minerals Crisis No One's Talking About - Amanda van Dyke

host Mar 22, 2026
  • Top takeaway The host frames the interview around market state, government incentive pricing, deglobalization, and the bear case for critical minerals.
  • He presses on how investors should treat the $110 NdPr price floor across projects lacking US deals, and whether EU weakness creates investment opportunity.

Amanda van Dyke argues global metals and minerals output must at least double again just to sustain today's economic level. Mining faces falling grades and a discovery drought, and she says copper and silver are already in global deficit. China's roughly $1 trillion, 25-year investment bought control of about 60% of the metals supply chain and 90% of some minor metals. US price floors like the MP Materials rare earth deal are project-specific financing guarantees, not a new global benchmark price. She avoids the EU after its 40% mining capacity loss, favoring the US, Latin America, and Africa for permitting and rule of law.

Junior Mining Stock Ghosts, PDAC Sentiment & Canada Funds Miners with Bill Powers & Brian Leni

Junior Mining Stock Ghosts, PDAC Sentiment & Canada Funds Miners with Bill Powers & Brian Leni

guest Mar 4, 2026
  • Top takeaway Views Canada's critical-minerals and processing push "highly, with high skepticism": he accepts there is little choice given Canada's dependence on the US, but says he will believe it only when ground is broken, and doubts both the government's ability to execute and that it will pick the right companies and projects.
  • Argues volatility is now the norm rather than the exception, and that investors without a firmly grounded thesis will be sent through the ringer; when things sell off he wants to be a buyer.
  • Thinks the current move is more likely a base or floor in this bull market than a top, particularly on the precious-metals side, where he expects sustained rather than merely elevated prices.
  • Says he only puts money behind companies he has conviction in — he has no staying power for market volatility in a story he does not believe in — and so focuses on highest-conviction picks rather than the behind-the-scenes "ghost" plays being described.
  • Reads the bulk-sampling wave as partly imitation, where companies copy a rival's move because that rival's share price jumped, and says a few direct questions reveal whether there is real reasoning behind a program.

Conference chatter at Vancouver's Metals Investor Forum and Toronto's PDAC showed corporates hunting deals, while generalist retail stayed absent. Government support lists — like British Columbia's critical minerals designations — validate projects for investors already holding them, but never justify a mediocre asset. Three junior mining “ghosts” — the purist, the apparitionist, and the Geppetto pulling strings behind management — explain why a junior rises without project progress. Bulk sampling is spreading through juniors; ask what the money funds, because selling high-grade surface ore cheaply erodes future mine value. Metal prices are only one reason to own a junior; Brian Leni models expected value per asset to separate commodity moves from marketing.
