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

Core Insights - The assays from the Company's maiden drillhole, RIBN-DD-001, at the RIB North Discovery have confirmed it as the best exploration hole drilled to date at the Angilak Uranium Project [1] - RIBN-DD-001 assays returned a total composite uranium mineralization of 34.7 meters, encompassing seven zones from 287.0 meters to 439.9 meters, surpassing preliminary results reported on September 23rd, 2025 [1] - The widest continuous intersection in the hole, from 426.3 to 439.9 meters, returned 13.6 meters of composite uranium mineralization grading 0.53% U3O8, including a notable 1.1 meters grading 4.81% U3O8, with the highest-grade sample returning 8.16% U3O8 over 0.5 meters [1] - Mineralization was first intersected in sandstone over three intervals between 287.0 meters and 351.1 meters, with the fourth zone intersected directly above the unconformity at 356.7 meters, extending into graphitic basement rock below [1]
