Alligator Rivers Uranium Province, Northern Territory |
Ownership: 100%
DevEx is targeting high-grade uranium at the Nabarlek Uranium Project, a district-scale tenement package in the Alligator Rivers Uranium Province (ARUP) in the Northern Territory. Following the completion of acquisitions from Alligator Energy and Rio Tinto Exploration, DevEx’s consolidated ARUP landholding now exceeds 9,200km².
The ARUP is among the world’s most prospective areas for high-grade uranium mineralisation, hosting over 730Mlbs of uranium endowment across mined and unmined deposits including Jabiluka (307Mlbs @ 0.55% U₃O₈), Ranger (300Mlbs @ 0.23% U₃O₈), Angularli (32.9Mlbs @ 1.09% U₃O₈) and the historical Nabarlek Mine.
At the heart of the project lies the historical Nabarlek Uranium Mine — Australia’s highest-grade uranium mine, with past production of 24Mlbs @ 1.84% U₃O₈. The project includes the Nabarlek Mining Lease and surrounding tenure.
Exploration
The discovery of large, high-grade fault-hosted unconformity-type uranium deposits — similar to the Nabarlek, Jabiluka or Ranger deposits — remains DevEx’s priority focus. Successful 2023–2024 drilling campaigns returned multiple high-grade uranium intercepts from prospects along the U40 Fault and the Nabarlek Fault Corridor surrounding the historical Nabarlek Mine.
Next Steps
In April 2026, DevEx Resources released its Exploration Strategy and Execution Plan which details the pipeline for the now expanded Nabarlek Project, incorporating the newly consolidated tenure and data sets.
Strategic pipeline established in a target rich environment:
- Priority drill-ready targets
- Emerging targets: Field exploration activities to advance to drill-ready status
- Advance access to explore large unexplored radiometric anomalies
