ATHA Energy Corp. has reported preliminary results from seven additional diamond drillholes at the RIB North Discovery within its 100%-owned Angilak Uranium Project in Nunavut, Canada. The company said every hole intersected uranium mineralization, while reported continuity along the primary RIB North structural corridor has reached 1.45 km.
#Results from seven drillholes
The results cover drillholes RIBN-DD-010 to RIBN-DD-016A, completed as part of the 2026 Angilak Exploration Program. Drilling is being conducted as widely spaced step-outs intended to outline the extent of mineralization. ATHA said the RIB North discovery remains open in all directions.
RIBN-DD-011 was drilled approximately ~250 m along strike to the northeast from RIBN-DD-001. It intersected 20.0 m of composite uranium mineralization across fifteen zones between 494.0 m and 700.5 m, including 1.3 m classified by the company as high-grade mineralization.
The strongest interval reported from RIBN-DD-011 measured 1.5 m between 661.5 m and 663.0 m. It recorded an average reading of 8,453 CPS and a maximum of 26,680 CPS, including over 0.6 m of high-grade mineralization.
RIBN-DD-013A, positioned approximately ~370 m along strike to the northeast from RIBN-DD-001, intersected 13.0 m over five zones between 544.0 m and 673.0 m. Its widest reported interval measured 4.0 m from 544.0 m to 548.0 m, with an average reading of 1,013 CPS and a maximum of 6,855 CPS.
RIBN-DD-014 intersected 7.0 m over six zones between 237.0 m and 573.0 m. Its highest-reading interval measured 1.5 m from 571.5 m to 573 m, averaging 4,275 CPS and reaching a maximum of 20,138 CPS.
On the secondary mineralized horizon, RIBN-DD-010 intersected 3.0 m over four zones between 412.5 m and 576.5 m. The widest interval measured 1.0 m from 540.5 m to 541.5 m, with an average reading of 718 CPS and a maximum of 1,407 CPS.
#Mineralized corridors and measurement basis
ATHA describes the primary RIB North mineralization as occurring on the eastern limb of the Mineralized RIB Corridor. A separate horizon on the western limb was first identified by RIBN-DD-008 and followed up with RIBN-DD-010. The company said mineralization on that secondary horizon has been traced over approximately ~220 m of strike length.
The company characterizes both horizons as basement-hosted, structurally controlled uranium mineralization associated with albite and hematite alteration, graphitic + sulphide-bearing structures and overprinting silicification.
ATHA defines high-grade mineralization as an interval with radioactivity above >10,000 CPS from a downhole gamma probe. The reported total gamma results use an average cutoff of >300 CPS over intervals of 0.1 metre width. The company said it previously used >500 CPS and changed the threshold based on assay results from 2024 & 2025.
Readings were obtained using a Mount Sopris 40TGU-1000 Triple Gamma Geiger down hole probe. The reported intercepts are core widths, and true thickness has not yet been determined. The results are preliminary, and the release states that there are no known mineral resources/reserves.
#2026 exploration programme
ATHA says diamond drilling with three drills began on May 1st, 2026, and is scheduled to continue through the end of September. The programme also includes aerial geophysics. The Expert's MMT survey was completed in late July, while the company anticipates receiving 3D Inversion Modeling results in Q4 2026.
The company says it will continue issuing preliminary results from the 2026 Angilak Exploration Program through the coming weeks. These are planned or anticipated activities and do not represent completed outcomes.
#Risks and qualifications
ATHA states that its forward-looking information reflects the company’s current view of future events and relies on assumptions and estimates that it considers reasonable. The company also says those statements are subject to significant business, market and economic risks, as well as competitive, political and social risks, contingencies and uncertainties.
The release identifies risks including difficulties completing exploration plans, failing to realise anticipated benefits or economic benefits from exploration, weather and other natural occurrences, accidents, personnel and equipment availability, aboriginal title, permitting and regulatory approvals, community relations, changes in uranium demand, supply and pricing, and general economic and political conditions. ATHA says actual results and future events could differ materially from those anticipated.
#Key Takeaways
- ATHA Energy reported preliminary results from seven additional drillholes at the RIB North Discovery.
- Reported continuity along the primary RIB North structural corridor has reached 1.45 km, and the discovery remains open in all directions.
