PROJECT UPDATE

Building a world-class uranium mining region

REGION

  • Alligator Rivers Uranium Province, some of the world’s largest uranium deposits on the north-western margin of the McArthur Basin, a basin with over 730Mlbs of uranium endowment
  • Established uranium mining jurisdiction of +40 years
  • The Right Area: Nabarlek receives strong Community Support backed by beneficial Agreements

PROJECT

  • Extensive tenure centered on historical Nabarlek Mine – Australia’s highest-grade uranium mine (Historical Production: 24 Mlbs @ 1.84% U3O8)
  • Multiple high-grade uranium intercepts from DevEx’s 2023 – 2024 drilling campaigns
  • Target rich environment, including recently granted tenure

NEW AQUISITIONS PIECE THE OPPORTUNITY TOGETHER

  • Extensive access to advanced exploration acreage along known uranium bearing fault zones including
  • Caramal to Nabarlek Fault Zones
  • Angularli to U40 Fault Zones incl Sandfire and Spitfire to U40
  • Advance targets on acquired of Rio Tinto Tenement Applications

STRATEGY

To discover another Jabiluka-type deposit

  • Right Rocks: Recognising the rocks which host Nabarlek and Jabiluka
  • Right Structures: Uranium faults: Nabarlek, U40 and Angularli Corridors
  • The Right Target: Where the Right Structure meets the Right Rocks

3 Caramal Inferred MRE – Refer Cautionary Statement below and ASX announcement dated 1 December 2025.

[1] Cautionary Statement (Refer DevEx Announcement, 1 December 2025 – DevEx to Acquire Alligator Energy’s Tenure, Alligator Rivers Uranium Province, NT): The Caramal Inferred MRE presented here was previously reported by AGE under the JORC Code 2004 to ASX on 19 April 2012, in an announcement titled “Alligator announces Caramal resource of 6.5Mlb U3O8 @ 0.31%”. It is acknowledged that:

  • the Inferred MRE has not been reported in accordance with the JORC Code 2012;
  • a Competent Person has not done sufficient work to disclose the Inferred MRE in accordance with the JORC Code 2012;
  • it is possible that following evaluation and/or further exploration work the currently reported estimates may materially change and hence will need to be reported afresh under and in accordance with the JORC Code 2012;
  • after review of the original AGE Inferred MRE, nothing has come to the attention of DevEx that causes it to question the accuracy or reliability of AGE’s Inferred MRE for the Caramal deposit; but
  • DevEx has not independently validated AGE’s Inferred MRE and therefore is not to be regarded as reporting, adopting or endorsing those estimates.
