DevEx Resources (ASX:DEV) outlines kilometre-scale uranium anomalies at Murphy West

DevEx Resources (ASX:DEV) has unveiled a series of early assay results from its surface geochemical sampling at the Murphy West Uranium Project in the Northern Territory, confirming the presence of kilometre-scale anomalies that point to significant uranium prospectivity in the McArthur Basin.

The findings strengthen comparisons with the Athabasca Basin in Canada, which is already recognised as one of the world’s most productive uranium provinces.

Highlights

• More than 650 soil samples collected, with results available for 450.

• Several kilometre-scale anomalies defined, elevated in uranium pathfinder elements such as lead, copper and beryllium.

• Geochemical signatures mirror those seen at the Junnagunna Uranium Deposit at Westmoreland in Queensland.

• Applications being prepared for drill permits, with shallow drilling to commence in April 2026.

• Exploration continues across ~10,000 square kilometres of tenure under earn-in agreements and applications.

The early stage results provide tangible encouragement for DevEx as it sharpens its focus on a district that has long been recognised as underexplored but highly prospective.

The company’s current sampling builds directly on radiometric and magnetic surveys flown in 2024, which identified multiple anomalies extending up to two kilometres in strike length.

The sampling strategy is noteworthy for its use of pathfinder geochemistry rather than direct uranium anomalies. At Westmoreland’s Junnagunna deposit, uranium mineralisation lies masked beneath volcanic cover and surficial sediments, producing no surface radiometric signature.

However, associated pathfinder elements persist through cover, allowing explorers to identify concealed targets. DevEx’s orientation work at Junnagunna with Laramide Resources validated this methodology, and the same elemental associations are now emerging across priority zones at Murphy West.

“These early results have already highlighted several exciting large-scale uranium targets, analogous to both the Westmoreland and Alligator River uranium deposits, for further follow-up,”

said DevEx Resources managing director Todd Ross. He added that the company is moving toward its first phase of drilling as targeting confidence increases.

Murphy West sits on the southern margin of the McArthur Basin, a region already hosting more than 700 million pounds of uranium endowment.

The basin has long been considered prospective for unconformity-type uranium deposits, with geological similarities to Athabasca where multiple tier-one operations have been established.

Importantly, the anomalies defined at Murphy West overlie strike extensions of the same stratigraphy that hosts known mineralisation further east, including Laramide’s 65.8 million pound Westmoreland resource.

DevEx holds its ground through a series of earn-in agreements with Transition Minerals and GSW Minerals, as well as applications under Trek Metals.

The project spans around 10,000 square kilometres of tenure, an expansive footprint that underpins the company’s ambition to secure district-scale optionality across both unconformity-style and Westmoreland-type uranium targets.

The immediate next step is further sampling to expand the anomalies already recognised, with positive results expected to underpin drill permitting ahead of a program scheduled to commence at the start of the 2026 field season in April.

For investors and industry observers, the results add to a growing body of evidence that the McArthur Basin may be poised for a renaissance in uranium exploration.

The combination of proven geological analogues, large underexplored tenements and methodical modern exploration sets the stage for DevEx to advance its position in a tightening global uranium market.
