Cameco CorporationC
Cameco Corporation is one of the world's largest publicly traded uranium producers, established in 1988 by the federal merger of two Crown corporations (Eldorado Nuclear Limited and the Saskatchewan Mining Development Corporation) and privatized via a 1991 IPO. Its two flagship, wholly-Saskatchewan Athabasca Basin assets are McArthur River (mine, in service since Dec 1999, Cameco 69.805% / operator) paired with the Key Lake mill (in service since 1983, Cameco 83.33%) -- together the world's largest, highest-grade uranium mine-and-mill combination, mined by remote-controlled raise-boring given ore grades far too radioactive for conventional entry mining -- and Cigar Lake (Cameco 54.547%, also Athabasca Basin, mined via ground-freezing and jet-boring for the same radiological reason), which began production in 2014. Cameco also holds a 40% JV interest in Inkai, Kazakhstan (Kazatomprom 60%, operator) and a 49% interest in Westinghouse Electric Company (acquired jointly with Brookfield Renewable Partners, closed Nov 2023) -- one of the world's largest suppliers of nuclear reactor equipment, fuel and services, serving roughly half of the world's operating nuclear power plants; this is a real, material, non-mining revenue stream that is not itself a mineable commodity and is therefore described here rather than tagged as a MinerCommodity. McArthur River/Key Lake experienced a production disruption earlier in 2026 and resumed full output by Q2 2026 (per Cameco's own 'operation resumes production' announcement); full-year 2026 consolidated production guidance (Cameco's share across all operations) is 19.5-21.5 million lbs U3O8.

- Dec 1999 · McArthur River (Cameco's flagship, controlling-interest asset, the world's largest high-grade uranium mine) commenced production in early December 1999. Year/month precision only. Cigar Lake (54.547% Cameco) came later, first production 2014; Inkai is a 40% non-controlling JV interest (Kazatomprom-operated) -- neither is used as the anchor here, same 'flagship controlling asset sets the milestone' convention as BHP/Escondida and FCX/Grasberg. · Source

Milestones are recorded only from a company's own dated disclosure. A milestone with no date shown is one we can confirm was reached but for which no date was disclosed — we don't estimate one. "Not yet reached" means exactly that, not that a date is missing. An "Expected" line likewise only ever reflects the company's own guidance (e.g. a study or permit decision targeted for a stated quarter) — most not-yet-reached milestones have none, and that absence means no such guidance has been disclosed, not that one is overdue.
A relative ranking of how closely this company matches the profile of juniors that have actually been acquired — not a probability, and not a reason to buy. Acquisitions are rare: only a few dozen significant deals happen a year across a universe of thousands of juniors, so even a high score here describes a long shot. The strongest signal the underlying research identifies — whether a major already holds a JV, earn-in, or 5–19.9% strategic stake — isn't tracked yet and is absent from this score.
