Atha Energy (TSX-V:SASK) has reported its widest uranium intersection to date at the Rib North Discovery on the Angilak Uranium Project in Nunavut, Canada.
The 2026 exploration program has outlined continuity of uranium mineralisation over 300m along strike from the maiden discovery hole.
Of the eight completed diamond drill holes, Atha intersected uranium mineralisation in six holes, with drilling focused on widely spaced step-outs to define the extent of the discovery.
Drill hole RIBN-DD-003 delivered the standout result, intersecting 37m of total composite uranium mineralisation over 15 zones from 541.7m to 652.0m depth.
The hole targeted uranium mineralisation approximately 120m along strike to the northwest from the original discovery hole RIBN-DD-001.
The widest mineralised interval within RIBN-DD-003 measured 8.5m of composite mineralisation from 541.7m to 550.2m, with an average reading of 696 counts per second (CPS) and a maximum of 4,612CPS.
The ‘highest-grade’ interval returned 4.5m of composite mineralisation from 571.7–576.2m, with an average reading of 4,589CPS and a maximum of 14,773CPS.
The company has also discovered a secondary east-west mineralised structure along the western limb of the mineralised rib corridor, approximately 1km from the main Rib North Discovery area.
Drill hole RIBN-DD-008 intersected 14m of total composite uranium mineralisation over nine zones from 398m to 646m depth.
“The initial results from the Mineralised RIB and Lac 50 Deposit Corridors continue to reinforce our belief that Angilak represents one of the most compelling uranium exploration opportunities in Canada, if not globally,” CEO Troy Boisjoli says.
Mineralisation at both horizons comprises basement-hosted vein-style uranium mineralisation associated with strong albite and hematite alteration, graphitic and sulphide-bearing structures and overprinting silicification.
The 2026 Angilak Exploration Program represents the largest to date on the project, comprising approximately 20,000m of diamond drilling using three rigs and aerial geophysics.
Drilling commenced on 1 May and is scheduled to continue through September.
Atha Energy is a Canadian uranium explorer advancing the Angilak Project in Nunavut, which includes the Lac 50 Deposit and multiple exploration corridors across the Angikuni Basin.
