DevEx Resources Makes Major Discovery at Sandfire Uranium Prospect
DevEx Resources Limited (ASX: DEV) has identified a high-priority uranium drill target at its newly acquired Sandfire Prospect in the Northern Territory's prestigious Alligator Rivers Uranium Province. The discovery positions DevEx directly along strike from Deep Yellow Limited's 32.9-million-pound Angularli Uranium Deposit, marking a significant development in one of Australia's most established uranium mining regions.
Furthermore, this strategic positioning demonstrates DevEx Resources' ability to identify and secure premium exploration opportunities within proven uranium territories.

Strategic Location in World-Class Uranium Territory
The Sandfire Prospect sits within the Alligator Rivers Uranium Province, a region analogous to Canada's prolific Athabasca Basin. This uranium-rich territory has contributed significantly to global uranium production over the past 40 years, hosting over 700 million pounds of uranium across multiple deposits.
Moreover, the DevEx Resources Sandfire Prospect discovery benefits from strategic positioning just 2.5 kilometres along strike from the Angularli Deposit. This deposit boasts a Mineral Resource Estimate of 32.9Mlbs @ 1.09% U₃O₈.
The proximity to this high-grade resource significantly enhances the exploration potential of DevEx's newly granted tenement.
| Regional Uranium Assets | Resource/Production | Owner |
|---|---|---|
| Angularli Deposit | 32.9Mlbs @ 1.09% U₃O₈ | Deep Yellow Limited |
| Nabarlek Mine | 10,858 tonnes U₃O₈ produced | DevEx Resources |
| Regional Total | 700+ million pounds | Various |
Comprehensive Exploration Programme Delivers Results
DevEx's systematic exploration approach at Sandfire has yielded compelling evidence of uranium mineralisation potential. In addition, multiple survey techniques have provided convergent data supporting the target identification.
Ground Gravity Survey
The company collected 1,102 gravity stations across a 5.5km² area, confirming the location of the Angularli Fault extending from the known deposit. The survey identified the intersection with the north-west trending Sandfire Fault.
These findings reveal structural controls that may concentrate uranium mineralisation at this critical geological junction.
Radiometric Anomaly Confirmation
The initial airborne radiometric (uranium) anomaly that attracted DevEx to the area has been validated and refined through the new gravity survey. According to the announcement, this anomaly sits precisely at the fault intersection.
This creates a compelling drill target where geological structures converge, enhancing the potential for significant uranium discovery.
Surface Geochemical Sampling
Surface sampling of termitaria (termite mounds) has revealed a coherent lithium-beryllium anomaly associated with the fault systems. These pathfinder elements demonstrate a close association with uranium mineralisation at the nearby Nabarlek Mine.
This association provides additional confidence in the target area and validates the DevEx Resources Sandfire Prospect discovery methodology.
The DevEx Resources Sandfire Prospect discovery encompasses 1.6 kilometres of strike length with multiple coincident anomalies positioning it as a priority drill target.
Understanding Unconformity-Type Uranium Deposits
Unconformity-type uranium deposits represent some of the world's highest-grade uranium resources. These deposits typically form where basement rocks meet overlying sedimentary formations.
They occur when uranium-bearing fluids migrate along fault structures and concentrate at the geological boundary between different rock types.
At Sandfire, uranium mineralisation is expected to occur at the base of MacArthur Basin sediments and within the underlying fault zones. This mirrors the nearby Angularli Deposit where mineralisation sits approximately 200 metres below surface.
This deposit type has produced some of the world's most significant uranium mines, including those in Canada's Athabasca Basin.
Key Characteristics of These Deposits:
- Extremely high grades compared to other uranium deposit types
- Structural control along major fault systems
- Occurrence at or near the boundary between basement and sedimentary rocks
- Association with specific pathfinder elements like lithium and beryllium
These geological characteristics make the DevEx Resources Sandfire Prospect discovery particularly compelling. The project exhibits all the hallmarks of a significant unconformity-type system.
Clear Path to Drilling Campaign
DevEx has positioned itself for immediate exploration advancement with comprehensive pre-drilling preparation. The company has systematically completed all necessary preparatory work.
Completed Activities:
- ✅ Aboriginal heritage clearance surveys
- ✅ Ecological surveys
- ✅ Target definition through multiple survey methods
- ✅ Drilling application submitted
Planned Timeline:
- April-May 2026: Drilling commencement at start of dry season
- Both diamond and RC drilling planned for comprehensive target testing
- 1.6-kilometre strike length identified for systematic exploration
The timing aligns perfectly with Northern Territory seasonal conditions. This allows for optimal drilling access and logistics during the dry season.
Investment Thesis: Strategic Positioning in Premium Uranium District
The DevEx Resources Sandfire Prospect discovery represents a compelling investment opportunity. It is built on several key advantages that distinguish it from other exploration plays.
Proven Geological Model
The company benefits from exploring in a well-understood geological environment with established uranium production history. The proximity to multiple known deposits provides confidence in the exploration model.
Furthermore, this reduces geological risk whilst maintaining significant discovery potential.
Strategic Infrastructure Access
Located within the established Alligator Rivers Uranium Province, Sandfire benefits from existing uranium mining infrastructure. The area features established regulatory frameworks and relationships with Traditional Owners and government authorities.
This infrastructure advantage significantly reduces development risk for any future discovery.
Compelling Target Metrics
According to the company's announcement, the DevEx Resources Sandfire Prospect discovery features multiple compelling characteristics:
- Multiple coincident anomalies (gravity, radiometric, geochemical)
- Structural intersection of two major fault systems
- Pathfinder element signature matching known uranium deposits
- 1.6-kilometre strike length offering substantial exploration potential
| Target Characteristics | Significance |
|---|---|
| Fault intersection | Enhanced mineral concentration potential |
| Radiometric anomaly | Direct uranium signature |
| Pathfinder elements | Proven association with local uranium deposits |
| Strike length | 1.6km of continuous exploration potential |
