NexGen Energy Ltd.N
NexGen Energy Ltd. (TSX/NYSE: NXE) is a Vancouver-headquartered uranium developer holding a 100% interest in the Rook I project (32 contiguous mineral claims, ~35,065 hectares, Athabasca Basin, Saskatchewan), anchored by the high-grade Arrow deposit. The Feb 2021 Feasibility Study reported an after-tax NPV8% of C$3.47B, after-tax IRR of 52.4% (at a US$50/lb U3O8 price assumption), probable mineral reserves of 239.6 million lbs U3O8 (4,575 kt grading 2.37% U3O8), a 10.7-year initial mine life, and average annual production of 28.8 million lbs U3O8 in years 1-5. The Canadian Nuclear Safety Commission approved the project's Environmental Assessment and issued a Licence to Prepare Site and Construct on 5 Mar 2026 -- the final federal regulatory approval needed -- and full-scale, licensed construction commenced 8 Jun 2026, targeting a ~4-year build (first production not expected before ~2030). Once in production, Rook I is expected to produce up to 30 million lbs U3O8 annually, more than 20% of current global uranium supply and more than half of Western-world output. An 'Interim Trend Update' has since raised the pre-production capital estimate from the 2021 FS's original ~C$1.3B to ~C$2.2B (US$1.58B) and life-of-mine cash operating costs from C$7.58/lb to ~C$13.86/lb U3O8, reflecting both inflation since 2021 and advanced engineering/procurement/constructability work -- this is a real, current, more-relevant capital figure and is what initialCapexUsd below cites, rather than the stale 2021 FS figure.

3 of 5 reached- Mar 2026 · Canadian Nuclear Safety Commission approved the Environmental Assessment and issued a Licence to Prepare Site and Construct for Rook I on 5 Mar 2026 -- the final federal regulatory approval needed (provincial EA approval had separately been granted in Nov 2023). Full-date precision, primary-company/regulator-announcement sourced. · Source
- Mar 2026 · NexGen's own communications describe the Final Investment Decision as already made by the time of the 5 Mar 2026 CNSC construction-licence announcement, but this pass did not find a distinct, separately-dated FID press release -- dated here to the 5 Mar 2026 announcement as the most precise confirmed date tying regulatory clearance to the construction decision, the same treatment DML's CONSTRUCTION_DECISION got when its own FID and construction-licence announcements coincided (Task #619). · Source
- Jun 2026 · Full-scale, licensed construction activities at Rook I commenced 8 Jun 2026 (team, procurement, engineering, vendors, contractors and capital in place; advanced site and shaft-sinking preparation underway), targeting a ~4-year build.

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.

Single-project company (Rook I only) -- no multi-asset ambiguity the way this backlog's diversified majors have. dcfNpvUsd/irrPct/mineLifeYears/technicalReportPriceAssumptionUsd below are all from the Feb 2021 Feasibility Study, which now pre-dates the real capital-cost and operating-cost updates described above (no updated post-2021 NPV/IRR figure was found this pass to replace it with) -- initialCapexUsd is the one figure updated to the more current ~US$1.58B Interim Trend Update estimate specifically because that figure was directly available in USD from a dated, sourced announcement.
