DevEx Resources has assembled a vast uranium exploration pipeline at its Nabarlek Project in the Northern Territory, identifying multiple high-priority targets for a funded 2026 drilling campaign. The strategy integrates new tenement acquisitions and advanced geophysical data to unlock one of Australia’s most prospective uranium districts.
- Multiple drill-ready uranium targets identified for 2026 campaign
- District-scale land consolidation from Alligator Energy and Rio Tinto acquisitions
- Integrated gravity, magnetic, and radiometric data underpin targeting
- Emerging high-grade rock-chip assays near Caramal uranium deposit
- Well-funded multi-year exploration strategy underway
District-Scale Uranium Pipeline Emerging at Nabarlek
DevEx Resources (ASX:DEV) has stitched together a significant district-scale uranium exploration pipeline at its 100%-owned Nabarlek Uranium Project in the Northern Territory, setting the stage for a major drilling push in 2026. This follows recent strategic tenement acquisitions from Alligator Energy and Rio Tinto, which have expanded the company's footprint within the prolific Alligator Rivers Uranium Province (ARUP), home to over 700 million pounds of uranium historically.
By consolidating these assets and integrating a suite of geophysical, geological, and drilling datasets, DevEx has unveiled multiple high-priority, drill-ready targets including Big Radon, KP, Sandfire, and Nabarlek North. These prospects exhibit compelling structural complexity and lie along key uranium-bearing fault corridors, enhanced by recent gravity, magnetic, and radiometric surveys.
Drilling is set to commence in June 2026 with an initial campaign targeting approximately 17,000 metres across 66 holes, marking the first phase of a multi-year, discovery-focused exploration strategy. The company is well-funded to execute this plan, backed by recent capital raises that have bolstered its cash position to support extensive fieldwork and land access activities.
High-Grade Assays and Structural Analogues Bolster Prospectivity
New rock-chip sampling near the historical Caramal Uranium Deposit has returned assays up to 0.31% U₃O₈, reinforcing the potential of emerging targets along fault corridors flanking Caramal. These results build on historical samples with grades as high as 2.1% U₃O₈, highlighting a mineralised system that remains open along strike beneath McArthur Basin sandstones.
DevEx’s technical team interprets these targets as part of broader uranium-bearing fault corridors analogous to major regional deposits like Nabarlek and Jabiluka. Recent re-logging of diamond drill core at Caramal confirms the presence of favourable host rocks, including prospective carbonate sequences, which are critical for unconformity-style uranium mineralisation.
These findings align with DevEx’s strategic approach to leverage integrated datasets to vector into structurally complex zones that offer the best chance of discovery. The company plans to enhance targeting through state-of-the-art airborne hyperspectral surveys, aiming to detect alteration minerals indicative of buried uranium deposits beneath sandstone cover.
Priority Targets and Exploration Pipeline Details
The Big Radon Prospect features a three-kilometre-long radon anomaly coincident with illite clay alteration, interpreted as a large-scale trap for uranium mineralisation. Detailed ground gravity surveys have identified significant fault dislocations that coincide with peak radon emissions, underpinning its status as a priority drill target.
Similarly, the KP Prospect hosts a two-kilometre radon anomaly aligned with a structurally disrupted fault zone, confirmed by gravity data to underlie radiometric anomalies and groundwater seepage zones. Sandfire Prospect, located along strike from the high-grade Angularli Uranium Deposit owned by Deep Yellow Limited (ASX:DYL), exhibits structural complexity at the intersection of major fault zones, making it a compelling inaugural drill target.
The Nabarlek North Prospect lies adjacent to the historical Nabarlek Mine and is interpreted to host extensions of known uranium-bearing faults that have seen limited historical drilling. This area will also be tested in the 2026 campaign, aiming to identify high-grade mineralisation on tighter drill spacing than previously achieved.
Broader Regional Targets and Land Access Progress
Beyond these immediate drill-ready targets, DevEx is advancing exploration across a broader portfolio that includes the Mustang, Corsair, Junction, and Skytrain prospects. These areas feature large, unexplored radiometric anomalies associated with northwest-trending fault corridors. The company is actively working with the Northern Land Council and Traditional Owners to secure land access over the next two years.
DevEx’s integrated approach and expanded landholding position it uniquely among Australian uranium explorers. The company’s Managing Director, Marnie Finlayson, emphasised the strategic shift from isolated prospects to a district-wide targeting framework, which has enabled a more coherent and compelling pipeline of uranium targets.
“Our expanded footprint and data integration have given us a genuine ‘light bulb’ moment, correlating the preferred settings for unconformity-style uranium deposits with major fault corridors and structural complexity,” Finlayson said. “This pipeline, many of which are drill-ready, positions DevEx to deliver Australia’s next significant uranium discovery.”
DevEx’s upcoming drilling campaign and exploration activities follow a series of recent capital raises and acquisitions that have strengthened its balance sheet and uranium portfolio, including a $38.9 million raise and new licences secured from Rio Tinto, as detailed in its recent $38.9 million capital raise and strategic acquisitions and $39M raise announcements.
Bottom Line?
DevEx’s district-scale consolidation and integrated targeting set a robust foundation for its 2026 drilling campaign, but the path to a significant discovery hinges on upcoming assay results and land access outcomes.
Questions in the middle?
- Will 2026 drilling confirm the structural traps indicated by gravity and radiometric data?
- How will hyperspectral surveys refine targeting beneath McArthur Basin sandstones?
- What impact will land access negotiations have on exploration timelines for broader regional targets?
