DevEx drilling strikes uranium at Nabarlek: restart signals for mine planners
Reviewed by Joe Ashwell

First reported on Australian Mining
30 Second Briefing
DevEx Resources has intersected shallow uranium mineralisation at the Nabarlek uranium project in the Northern Territory, with first-pass drilling returning up to 1.7m at 1116ppm uranium equivalent and 2.3m at 920ppm at the Nabarlek North prospect. The intersections come from a 40‑hole, 11,050m reverse circulation and diamond drilling campaign across four priority targets around the historic Nabarlek mine. Results suggest continuity of mineralisation along key structures, signalling follow‑up step‑out drilling and closer‑spaced resource definition work for potential restart studies.
Technical Brief
- Mineralisation was intersected at shallow depths, implying relatively short drill hole lengths for key hits.
- Structural continuity of uranium-bearing zones was observed along mapped faults and shear corridors.
- First-pass programme layout focused on step-out holes from known historical workings and anomalies.
- Diamond tails provide core for structural logging, alteration mapping and density / geotechnical measurements.
- RC pre-collars accelerate penetration through cover sequences before entering prospective basement lithologies.
- Results set up tighter-spaced follow-up drilling needed for JORC-compliant resource definition and restart studies.
Our Take
DevEx Resources’ recent leadership change and A$7.5 million move on Alligator Energy, noted in our uranium coverage, suggests the Nabarlek uranium project drilling in the Northern Territory is part of a broader push to scale a multi-asset uranium portfolio rather than a single-asset play.
Within our 42 uranium-tagged pieces, most Australian stories centre on regulatory and market dynamics rather than early-stage drill intervals, so these 1.7–2.3 m mineralised hits at Nabarlek North position DevEx among the more technically advanced junior explorers in the domestic uranium space.
The 40-hole, four-target drilling program at Nabarlek North indicates a relatively tight, hypothesis-driven campaign; in our database, similar-scale uranium programs in Australia often precede either a focused resource-definition phase or strategic farm-in discussions if follow-up results hold up.
