The Fort Worth Press - ATHA Completes Angilak Mobilization & Commences Ground Geophysics to Target Unconformity-Style Discovery

VANCOUVER, BRITISH COLUMBIA / ACCESS Newswire / April 30, 2025 / ATHA Energy Corp. (TSX.V: SASK)(FRA:X5U)(OTCQB:SASKF) ("ATHA" or the "Company"), holder of the largest uranium exploration portfolio in two of the highest-grade uranium districts globally, is pleased to announce completion of mobilization to its 100%-owned Angilak Uranium Project, Nunavut. The Company also commenced ground gravity and EM surveys at the project that are focused on regional target areas along the 31 km Rib-Nine Iron Trend, which extends beneath the cover of the Angikuni Basin (Figure 1). ATHA's objective of the ground gravity and EM surveys is to vector in on targets to be drilled as part of the Company's 2025 Exploration Program for which drilling is anticipated to commence in early June.

The Angilak Uranium Project is situated within the Angikuni Basin, approximately 225 km southwest of Baker Lake in the Kivalliq Region of Nunavut (Figure 1). Numerous historic regional discoveries of uranium mineralization have been made outside of the Lac 50 Deposit area, both within the Angikuni Basin as well as along the Basin margins. The geophysical surveys will focus on defining high priority targets identified across the 31km Rib-Nine Iron Trend, located ~30 km southwest of the Lac 50 Deposit, situated along the western margin of the Angikuni Basin and transecting the Angikuni Basin.

Figure 1: Angilak Project Area and Mapped Mineralized Outcrops, Surface Showings of Uranium and Historic Drilling Results by Prior Operators (see References for Historic Diamond Drilling) *Notes and References for Historic Diamond Drilling assessment reports:

^IPrevious operators of the Angilak Project completed 24 diamond drill holes in the Dipole Showing and intersected grades of up to 5.53% U₃O₈ over 0.5 m ^2,3,5,6
IIAlong the western margin, historic drilling (by prior operators) at the RIB Discovery intersected shallow (3O₈ ^1,2,3, hosted within graphitic pelitic rocks with Athabasca unconformity style alteration
^III Mushroom Lake surface outcrop spans an area of 3 km on surface with historical outcrops samples grading up to 47.8% U3O8 ^4,5,6
IV Nine-Iron showing with 5 historical diamond drill holes. Intersections of shallow uranium mineralization, grades up to 1.25% U3O8 and historical outcrops with grades up to 30.3% U3O8 ^5,6

Between 1977 and 1979, Noranda Exploration Company completed 30 diamond drill holes at the Rib Discovery, intersecting Athabasca Basin unconformity-style alteration, structure, and lithologies associated with shallow (3O₈ hosted within graphitic mylonites ^1,2,3. After integrating historic drill results with ATHA's 2024 MMT survey results and the recent structural interpretation completed by SRK, the scale and potential of the Rib-Nine Iron Trend is evident and suggestive that it has potential to host multiple additional unconformity and basement-type uranium mineralized zones along the 31 km trend.

As was typical of 1970 - 1980's Athabasca Basin exploration, the maximum depth of drilling at Rib is ~100 m, ending in what is now considered to be prospective alteration and lithologies. The 2024 MMT survey demonstrated that the prospective conductive horizon extends from surface to depths of more than 1 km, within and along the margins of the Angikuni Basin. The Angilak Project, both within the Angikuni Basin and along its periphery, are compatible with a structural architecture that supports a target-rich environment for discovery of uranium mineralization.
