Uranium explorers & developers
The junior end of the sector, organized the way it's valued: disclosed resource levels. Every resource figure links to the company disclosure that published it; market caps are computed live from each company's primary listing (ASX, TSXV, TSX). These companies also appear as the explorer tiers of the uranium stocks screener → alongside the producers; this page is the deep view with per-project citations. For mine-stage projects and operating assets, see the project table and the mines map.

Exploration targets †
The potential quantity and grade of an Exploration Target is conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource. Ranges are shown exactly as each issuer disclosed them and are never added to the resource figures above.
- Laramide Resources — Westmoreland district (eight satellite prospects) (Queensland / NT, Australia): 19.4–102.5 Mt · 624–817 ppm U3O8 · 26.7–184.8 Mlb contained · 2026-06 [1]Reported under JORC 2012 across eight named prospects within 20 km of Westmoreland; stated as independent of and additional to the Apr 2024 MRE.
- Premier American Uranium — Cyclone ISR (Cyclone Rim + Osborne Draw) (Wyoming, USA): 7.9–12.6 Mlb contained · 2024-08 [1][2]Tonnage filed as 6.5-10.5 million short tons at a single 0.06% eU3O8 average grade (not ranges), so only the contained-metal range is shown as filed.
- American Uranium — Lo Herma (by sand horizon) (Wyoming, USA): 5.88–7.9 Mt · 500–700 ppm U3O8 · 2026-08 [1]Restated net of areas converted into the updated 9.96 Mlb MRE; filed as American Uranium (ASX:AMU). No contained-metal range filed.
- American Uranium — Great Divide Basin (Green Mountain) (Wyoming, USA): 6.55–8.11 Mt · 420–530 ppm U3O8 · 2023-04 [1]First reported Apr 2023; restated unchanged Aug 2026, additional to the 1.66 Mlb GDB Inferred resource.
- Elevate Uranium — Oobagooma (Kimberley) (Western Australia): 650–950 ppm U3O8 · 26–52 Mlb contained · 2021-09 [1]Filed as grade and contained-metal ranges only (no tonnage range). Project is under a pending divestment to Orpheus Uranium announced Oct 2025; still held as of Aug 2026.
- Cauldron Energy — Yanrey (project-wide, 30 prospective areas) (Western Australia): 130–390 Mt · 294–604 ppm U3O8 · 89.7–269 Mlb contained · 2026-06 [1]Additional to the ~55 Mlb of defined Yanrey resources; grades pair with tonnage cases as filed (294 ppm with the 130 Mt lower case, 604 ppm with the 390 Mt upper). Supersedes the Jan 2024 and May 2026 targets.
- ATHA Energy — Angilak — Lac 50 trends (Nunavut, Canada): 3700–4800 ppm U3O8 · 60.8–98.2 Mlb contained · 2024-11 [1][2]Grade filed as 0.37%-0.48% U3O8 (shown here in ppm); no tonnage range filed. Restated under the Oct 2025 amended technical report that also retracted the 2013 historical estimate; distinct from any mineral resource.
Methodology
Real- Tiers
- Developer: a published economic study (scoping/PEA, PFS, or DFS) or permitting/financing stage. Explorer: a compliant JORC or NI 43-101 resource with no published economics. Greenfield: active drilling with no current compliant resource; historical estimates appear as text notes only, never as figures.
- Resource figures
- Contained (in-situ) Mlb U3O8 exactly as each company discloses it, mixed confidence categories per row; not ore reserves and not recoverable pounds. Rows are disclosure snapshots, not interchangeable inventories, and are never summed with the producer table on /uranium-stocks. The ∑ mark flags a total we summed from the source's stated categories rather than a figure it prints verbatim.
- Market caps and ratios
- Market caps are computed live from the primary listing via EODHD (shares x price x FX) and never stored. MCap/lb divides the live cap by disclosed contained pounds: a screening ratio, not a valuation (it ignores cash, debt, ownership splits, category confidence and metallurgy). Green marks rows at or below the tracked median. EV/lb subtracts last-reported cash from the live cap; debt is not subtracted, and no tracked company carries material debt.
- Cash and runway
- Cash is the last-reported balance from each company's most recent quarterly filing: the ASX Appendix 5B, or quarterly/annual financial statements for Canadian listings. The filed figure is stored in its filing currency and converted to USD at the live rate. "Qtrs stated" republishes the issuer's own estimated quarters of funding available from its 5B, never our forecast. A stale tag means the figure has missed a full quarterly reporting cycle.
- Mining method and studies
- The method pill is the issuer-stated development concept per project, marked TBD when the issuer has not stated one. ISR is highlighted because ISR deposits tend to run lower grade yet price higher per pound. The study pill links the most advanced published economic study (a PEA counts as scoping); in-progress studies do not count, and a published study is what places a company in the developer tier.
- Exploration targets
- Conceptual range estimates under JORC Clause 17 / NI 43-101 s.2.3(2), listed separately with the mandatory cautionary statement and shown exactly as filed; a dimension filed in other units or as a single average stays in the note, unconverted. Targets are never added to resource totals. The † mark on a row jumps to the list.
- Citations
- Every figure links the issuer disclosure that published it: a dated announcement, technical report, or the company's current resource page. Where an issuer's site blocks automated verification, two independent full-text records are cited instead. Numbered links are the supporting documents per row (hover for the document name); hover a row for its status note. Cited links are swept weekly for link rot.
