ATHA Energy Confirms New High-Grade Discovery at Angilak Project - Rib North, Maiden Hole Returns Assays with 34.7 m of Total Composite Uranium Mineralization, Including 13.6 m Grading 0.53% U3O8, 1.1 m Grading 4.81% U3O8, and Grades Up to 8.16% U3O8

On November 20, 2025, ATHA Energy announced the first assay results from its maiden drill hole (RIBN-DD-001) at the new Rib North discovery on its Angilak Project in Nunavut. The results confirm a significant, high-grade uranium discovery.
Key highlights from the drill hole include: - A total composite intersection of 34.7 metres of uranium mineralization across seven zones. - The widest continuous intersection was 13.6 metres grading 0.53% U3O8. - This wider zone included a very high-grade sub-interval of 1.1 metres grading 4.81% U3O8. - Peak grades of up to 8.16% U3O8 were assayed.
The CEO, Troy Boisjoli, stated that the intersection surpassed the company's expectations and that he could not "recall a maiden hole into a target area that returned of an intersection this significant." The company has completed 21 drill holes in the 2025 program, all of which intersected mineralization, with the remaining assay results expected in Q4 2025.
This news is a game-changing event for ATHA Energy. While the market was aware of a discovery at Rib North from the September 23, 2025 news release (which was based on scintillometer readings), these official assay results confirm and exceed expectations for the high-grade nature of the mineralization.
ATHA Energy Corp. is a Canadian uranium exploration company focused on delineating and discovering high-grade uranium deposits in tier-one jurisdictions.
Its flagship asset is the Angilak Uranium Project in Nunavut, Canada. The project hosts the historical Lac 50 Deposit, which is one of the largest high-grade uranium deposits outside the Athabasca Basin. ATHA's primary exploration thesis is that the Angikuni Basin, which hosts the project, is a direct and underexplored analog to the prolific Athabasca Basin. The company's recent focus has been on regional exploration along the 31 km Rib-Nine Iron Trend, leading to multiple new discoveries in 2025, culminating in the high-grade Rib North discovery.
