ATHA Energy Completes Mobilization & Commences Diamond Drilling Operations as Part of the 2026 Angilak Exploration Program – Fully Funded and Largest to Date at the Project
5 May 2026
HIGHLIGHTS
The 2026 Angilak Exploration Program, is fully funded with the February closing of CAD $63 Million financing, making ATHA one of the best capitalized uranium exploration Companies globally;
ATHA completed mobilization to Angilak in late April – including the arrival of a third diamond drill rig – and commenced diamond drilling operations on May 1st, 2026;
The 2026 Angilak Exploration Program is focused on expansion and discovery of uranium mineralization across the three mineralized corridors (Figure 2), building upon the highly successful 2024 and 2025 campaigns;
Over the two previous programs, ATHA has had unparalleled success, intersecting uranium mineralization in 100% of targets tested. During the 2025 campaign – focused on testing regional targets outside of the Lac 50 Deposit Exploration Target3 area, within the Angikuni Basin – the Company made five new regional discoveries, including the Mineralized RIB Corridor with four new showings;
2026 Angilak Exploration Program will be the largest to date at the Angilak Uranium Project, with two primary components:
Diamond drilling operations: Commenced on May 1st, with three drill rigs scheduled to complete ~20,000 m, continuing through September, focusing on:
Mineralized RIB Corridor: Additional discovery potential and expansion, following up on the highly successful 2025 program, which resulted in the four discoveries of uranium mineralization – including RIB North, where the maiden hole intersected 34.7 m of composite uranium mineralization1 with grades up to 8.16% U3O8 over 0.5 m;
Lac 50 Deposit Corridor: Testing recently identified, highly prospective, targets along strike from the main Lac 50 Deposit area, and expansion of the Lac 50 Deposit mineralization footprint, which remains open and unconstrained.
KU-Nine Iron Corridor: Testing recently identified, highly prospective, targets which directly vector from uranium mineralization intersected in the 2025 KU and historic Nine Iron Discoveries;
Geophysics: Expert Geophysic’s Aerial MMT (EM) survey, scheduled to commence at the end of June:
Angikuni Basin: Acquiring full MMT coverage across the 100% ATHA-owned Angikuni Basin. The resulting survey data will then be used to develop a 3D Inversion model of the entire Angikuni Basin. The same highly successful systematic approach ATHA utilized during the 2025 campaign – adding to ATHA’s already extensive portfolio of regional targets.
