Why Owning 47 Juniors Is the Fastest Way to Guarantee Mediocrity (or Worse)
Let’s be brutally honest for a second.
If your junior mining “portfolio” looks like a 47-line Excel sheet with an average position size of 2.1%, you didn’t build a portfolio.
You built a museum of hope certificates.
At CanadianMiningReport.com we’ve watched this play out every cycle since 2002. The guy with 6–10 concentrated bets, made at the right time with the right teams, walks away with millions. The guy with 45 “diversified” lottery tickets ends the bull market with a spreadsheet full of $0.02–$0.09 rounding errors and a vague memory that “a few of them went up for a week in 2021.”
Over-diversification in mining portfolios isn’t diversification. It’s performance euthanasia dressed up as prudence.
Here’s exactly why owning too many junior mining stocks is one of the biggest junior mining investment mistakes you can make — and how to fix it before the current cycle punishes you again.
The Math Doesn’t Lie — Over-Diversification Kills Upside Dead
In a typical commodity bull cycle:
~5% of juniors deliver 20–100x returns
~10–15% deliver 5–15x
~30% go sideways or slowly bleed
~50% go to zero or close enough
If you own 40 names, basic probability says you’ll own roughly:
2 screaming winners
5 decent winners
12 breakevens
21 corpses
Your portfolio return? Somewhere between 2–4x. Maybe 6x if you got lucky on the weighting.
Now give the same capital to someone who owns only the 6 best names in that same cycle. Their return? 15–50x or more.
Same cycle. Same stocks available to everyone. One person captured the asymmetry. The other person diluted it into mediocrity.
That’s the cold, hard mathematics of over-diversification in junior mining. The upside is finite and violently concentrated. Spreading yourself too thin is the same as volunteering to miss it.
The Emotional Root of the Problem
Over-diversification isn’t a strategy. It’s a coping mechanism for three toxic emotions that destroy junior mining returns:
Fear of missing out (FOMO)
“What if THIS is the next Great Bear and I don’t own it?”
Fear of being wrong on a single name
“If I only own eight and one blows up, I’ll look stupid.”
Fear of watching cash sit idle
“I’ve got $180k burning a hole in my account — I better put it to work in 28 different things.”
The result? You end up owning every promoted deal that crosses your inbox because saying “no” feels harder than saying “yes, another 18 cents.”
That’s not investing in junior mining companies. That’s panic-collecting.
Real-World Example: The 2020–2022 Uranium Cycle
Let’s run the numbers on a real cycle everyone remembers.
Top uranium winners 2020–2022 (peak to trough):
Paladin +4,200%
Deep Yellow +3,100%
Boss Energy +2,800%
Peninsula +2,500%
Lotus +2,100%
NexGen +1,200%
Denison +1,100%
The guy who owned only those seven names (concentrated, not 70) turned $200k into $8–14 million.
The over-diversified uranium “expert” who owned 48 names (yes, we know several) including all the garbage that raised at $0.15 and now trades $0.02? He turned $200k into $600k–$1.2 million and bragged about “only being down 40% from the top.”
Same bull market. One captured the move. The other diluted it into a rounding error.
How Much Diversification Is Actually Too Much?
Here are the hard limits we enforce with our own money and with private accounts we advise:
Maximum 12–15 total junior positions at any time
Maximum 8–10 core convictions (3–10% each)
Maximum 5–7 smaller “lottery ticket” bets (1–3% each)
Never more than 3 names in the same camp/metal unless one is clearly the elephant
Zero tolerance for new positions just because “there’s cash left”
If you can’t explain — out loud, in under 60 seconds — why you own a specific junior and why it deserves capital over everything else on your watchlist, you have no business owning it.
The Psychology of Mining Stocks: Why Concentration Feels Wrong (But Wins)
The human brain hates concentration in illiquid, volatile sectors. Watching one name drop 60% in a month while the sector is fine feels like death — even if your other five are up 150%.
So what do most people do? They average down on the loser and add three new names “to reduce risk.”
Congratulations. You just turned a temporary paper loss into permanent capital destruction and diluted your winners.
The winners don’t care about your feelings. They concentrate when blood is in the streets, hold through the noise, and sell when the crowd finally shows up.
The Only Junior Mining Stock Strategy That Actually Works Long-Term
Wait for generational fear (late 2015, late 2020, late 2022, late 2025 tax-loss season)
Ruthlessly rank every opportunity using the checklists from our previous reports (jurisdiction, people, grade, structure, catalysts)
Pick only the top 6–10 that score 9/10 or better
Size them meaningfully (5–12% each at cost)
Add only on extreme weakness, never on strength
When one doubles or triples, sell enough to get your original capital out and let the rest ride
Repeat every 3–5 years
That’s it.
No 47-line spreadsheet. No “just in case” 1% positions. No emotional averaging down on dying stories.
Common Diversification Mistakes Junior Mining Investors Make (And How to Avoid Them)
Mistake 1: Confusing quantity with safety
40 juniors isn’t safer than 8. It’s 40 chances to be wrong instead of 8 chances to be spectacularly right.
Mistake 2: Adding new names instead of adding to winners
The portfolio that goes from 8 names to 9 because you found another “great deal” is the same portfolio that goes from 9 to 47 in 18 months.
Mistake 3: Treating all juniors as equal probability
A Lundin-backed high-grade discovery in Red Lake is not the same as a $0.06 shell with a recycled Quebec gold project run by a serial diluter.
Mistake 4: Using diversification as an excuse to avoid doing real work
It’s easier to own 30 names than to admit you can’t tell the difference between the 5 good ones and the 25 bad ones.
The Bottom Line
Over-diversification in junior mining isn’t prudence. It’s fear wearing a risk-management mask.
The asymmetry in this sector is obscene — but only if you let it be. Own too many names and you guarantee yourself index-like returns in a sector that exists for the sole purpose of delivering non-index returns.
The next time you’re tempted to click “buy” on the 19th junior because “it’s only 1.8%,” ask yourself one question:
“Would I rather explain to my future self why I owned 8–10 of the best and made millions… or why I owned 47 and made 3% a year after fees and heartbreak?”
We know which conversation we’d rather have.
