Every uranium supply story in Canada eventually runs through Cameco (CCJ), the country’s dominant producer and the anchor of the Athabasca Basin that Gerardo Del Real’s “$10 Trillion Energy Stone” pitch treats as the geology everything else rests on. Cameco is not one of the pitch’s teased picks, which is itself telling. It is the benchmark those picks are measured against, the company with the mines, the cash flow, and the production the juniors can only dream of.
The Two Flagship Mines
Cameco’s production rests on two of the highest-grade uranium mines on earth, both in Saskatchewan’s Athabasca Basin. McArthur River is the world’s largest high-grade uranium mine, an underground operation that has been the backbone of Cameco’s output for decades. Cigar Lake is the world’s highest-grade uranium mine, running around 16% uranium oxide by weight, a grade so rich that the ore is handled by remote control to protect workers from radiation.
The ownership structure on Cigar Lake tightened in 2025, when Cameco and its partner Orano Canada bought out the remaining 5% stake held by a Tepco subsidiary. The deal lifted Cameco’s interest to 57.418% and Orano’s to 42.582%, giving the two companies full ownership between them. Cigar Lake had produced roughly 174 million pounds of uranium by the end of 2025, and Cameco guided toward 17.5 to 18 million pounds of production in 2026.
Cameco’s Role in the Cycle
Cameco’s importance to the uranium story is that it is one of the few companies on earth that can actually move supply in response to price. The company has a history of idling or curtailing production when uranium prices fall, which it did through much of the 2010s, holding its high-grade pounds off the market to wait for better economics. When prices recover, Cameco can restart and ramp capacity faster than any of its Western peers, which makes it the swing producer of the non-Russian world.
That lever cuts both ways. Cameco’s willingness to throttle production means it is not a pure price play, but it also means the company is disciplined about not flooding a weak market. For investors, that translates into a producer that survives downturns and benefits from recoveries, the exact profile the Energy Stone pitch holds up as the “safest way” to own the story.
Producers vs. the Juniors
The contrast between Cameco and the juniors Del Real actually sells is the most instructive part of the pitch. Cameco has revenue, licensed mines, and decades of production history. The two teased explorers, ATHA Energy and Skyharbour Resources, have land positions and drill programs and nothing else yet. The pitch is honest enough to structure itself around a producer as the safe anchor, then to sell the subscription on the explorers’ upside.
That structure is worth preserving in your own thinking. Cameco will not deliver the thousand-percent return a discovery can, but it will not go to zero either. It is the ballast, the position you hold through the volatility, while the juniors are the lottery tickets you size small enough to survive losing.
The Verdict on the Giant
Cameco is the cleanest single-stock way to own the uranium supply squeeze with the lowest company-specific risk, which is why it anchors most serious uranium allocations and why it anchors the logic of the Energy Stone pitch even though it is not for sale in that presentation. Its limitation is upside: the stock already reflects much of the sector’s recovery, and the outsized returns will come from further down the risk curve, if they come at all.

The Contract Book and AI Demand
Cameco’s value is not just the pounds it mines this quarter; it is the contract book that stretches years into the future. The company sells a large share of its output under long-term contracts with utilities, which locks in revenue visibility and smooths the spot-price swings that punish smaller players. That contract structure is a large part of why Cameco can ride out a weak uranium market that would break an explorer. When the spot price recovers, Cameco benefits on the margin, but it is never fully at the mercy of the daily quote.
The newer wrinkle is the AI-driven demand story that powers the Energy Stone pitch. Data centers need firm, carbon-free power, and the restart of reactors, along with planned new builds, feeds directly into the same utility demand that Cameco’s contracts serve. That is genuinely bullish for Cameco over the long term, but it is also a story the market has already partly priced in. Cameco is the safe way to own the uranium cycle, not the way to capture a tenfold move.
