DevEx Resources has completed the first month of its 2026 dry season drilling campaign at the Nabarlek Uranium Project in the Northern Territory, intersecting strongly altered basement rocks and fault breccias across its priority targets.

The company has consolidated a district-scale land position of approximately 9,200 square kilometres across the Alligator Rivers Uranium Province following recent acquisitions from Alligator Energy and Rio Tinto.

First-pass drilling at Big Radon confirmed a 20-metre-wide fault zone along the western edge of the targeted anomaly, intersecting shallow uranium mineralisation that returned 1.6 metres at 680 parts per million equivalent uranium octoxide from 26 metres down-hole, including 0.4 metres at 1,041 parts per million equivalent uranium octoxide, with laboratory assays pending.

At the KP Prospect, drilling has passed through approximately 100 metres of sandstone cover into altered basement rocks resembling those at the Nabarlek deposit. A diamond hole intersected an altered fault breccia above the unconformity infilled with semi-massive chlorite and hematite. Additional diamond holes are planned at the KP Prospect to test the fault breccia where it is projected to cross directly beneath the unconformity.

“Early drilling at an unconformity-style uranium target is about answering three critical questions; is the fault where we predicted it? Does it sit in the right rocks? And is uranium present within the system?”

“One month into our drilling campaign, and we have started to answer these questions. At KP we are drilling into altered basement rocks that look a great deal like the rocks that host Nabarlek. That is exactly the sort of information a first pass should deliver, and this data will be used to inform future activities.”

Meanwhile, reverse circulation drilling has started on the projected extension of the Angularli Fault Zone at the Sandfire target, along strike from Deep Yellow's Angularli deposit.

Relogging of historical drill core around the Caramal Uranium Deposit has also identified a potential northern continuation, down-faulted and sitting deeper than most historical drilling reached. DevEx is awaiting regulatory approval from the Northern Territory regulator for drilling applications lodged in June covering the Caramal target and four other prospects.

First-pass results from an airborne hyperspectral survey flown across the project area to detect alteration signatures are expected in September 2026.
