ATHA Energy Corp. (TSX.V: SASK) (FRA: X5U) (OTCQB: SASKF) is a Canadian uranium exploration company focused on its 100%-owned Angilak Uranium Project located in Nunavut, Canada. The company is developing what it believes could become Canada's newest uranium jurisdiction through systematic exploration of the Angikuni Basin's extensive graphitic structural corridors.

Major Discovery at RIB North

The company's latest drilling campaign has produced its most significant results to date at the newly discovered RIB North target. Located approximately 1.4 kilometers along strike from the nearest drillhole at the RIB East Discovery, the maiden hole RIBN-DD-001 delivered exceptional results that CEO Troy Boisjoli described as representing "a distinct achievement, not only for the 2025 Angilak Exploration Program, but for the Company as a whole."

The drillhole intersected 26.3 meters of total composite uranium mineralization across 10 zones, spanning from 345.55 meters to 460.05 meters depth. Within this broader mineralized envelope, the hole encountered 13.6 meters of continuous mineralization between 426.25 meters and 439.85 meters, including 1.7 meters of high-grade mineralization with peak radioactivity of 55,730 counts per second.

VP Exploration Cliff Revering emphasized the significance of these results, stating: "Our team has now discovered uranium mineralization across a 12 km graphitic structural corridor, and the results from the first RIB North drillhole, located over 1.4 km away from the nearest drilling, demonstrate impressive scale and continuity."

Geological Characteristics & Deposit Style

The mineralization at RIB North exhibits characteristics that management believes are analogous to major uranium deposits in the Athabasca Basin. The uranium mineralization was first encountered directly above the unconformity at 356.7 meters depth, extending into graphitic basement rock. The widest intersections are basement-hosted, vein-style uranium mineralization associated with strong hematite alteration, graphitic structures, and overprinting silicification.

Boisjoli, drawing on his experience in the Athabasca Basin, noted:

"From my previous experience working in both exploration and production across the Athabasca Basin, I am keenly aware of the geological characteristics of basement hosted style uranium deposits. ATHA's first hole at the RIB North Discovery, RIBN-DD-001, displays similar grades and thicknesses as other discovery holes from major basement deposits."

Expanding the Mineralized RIB Corridor

The company's systematic exploration approach has successfully outlined uranium mineralization across a 12-kilometer-long structural corridor. The Mineralized RIB Corridor (MRC) is now defined by over 12 kilometers of stacked conductors based on electromagnetic inversion modeling, with two distinct limbs showing extensive mineralization.

Along the eastern limb, uranium mineralization has been traced over a potential 4.4-kilometer strike length, extending from RIB South through RIB East to the newly discovered RIB North. The parallel western limb demonstrates mineralization over approximately 4.0 kilometers, extending from the Historic RIB Discovery through to the RIB West Discovery.

Additional drilling at RIB South produced more modest results, with maiden drillhole RIBS-DD-001 intersecting low-grade mineralization over three zones totaling 2.1 meters of composite mineralization. On the western limb, drillhole RIBW-DD-003 intersected continuous uranium mineralization over 1.8 meters, including 0.2 meters of high-grade mineralization with average radioactivity of 2,635 counts per second and a peak of 16,030 counts per second.

Technical Methodology & Quality Assurance

ATHA Energy employs rigorous technical standards in its exploration program. Radiometric surveying utilizes a Mount Sopris 40TGU-1000 Triple Gamma Geiger down-hole probe for accurate measurement of radioactivity levels. The company defines high-grade mineralization as any interval with radioactivity exceeding 10,000 counts per second from downhole gamma probe measurements.

Core samples undergo analysis at Saskatchewan Research Council (SRC) Geoanalytical Laboratories in Saskatoon, an ISO/IEC 17025:2005 accredited facility recognized by the Standards Council of Canada. The analytical suite includes multi-element analysis using partial and total digestion inductively coupled plasma methods, boron analysis by Na2O2 fusion, and uranium analysis by fluorimetry.

Market Context & Strategic Positioning

Management has positioned the discovery within the broader context of uranium market dynamics and strategic considerations. Boisjoli referenced recent US government announcements regarding strategic uranium reserves, noting:

"This comes on the heels of the recent announcement by the US government for the need to increase their strategic reserves beyond the current 14-month stockpile the US' current annual demand is 50 million lbs U3O8."

The CEO drew comparisons to other significant uranium discoveries, suggesting that "when coupling the results from RIB North with the cumulative discoveries made across the 12 km long MRC, the evidence is stacking up that the MRC has the potential to host discoveries like those found along the Patterson Lake Corridor."

Future Exploration Potential

The company's technical team maintains an optimistic outlook for continued discovery success across the broader Angilak project area. Revering expressed confidence in the exploration strategy, stating:

"These results highlight how our technical team is successfully translating a robust targeting strategy into meaningful new discoveries and set us up for a very exciting year ahead."

The MRC remains open along its entire 12-kilometer length, with significant unexplored ground between the currently defined discoveries. This provides multiple targets for future drilling campaigns and suggests potential for additional discoveries beyond the current resource base.

The technical team's thesis that "the Angikuni Basin is an emerging new uranium district with substantial scale potential is steadily being validated" through systematic exploration success across multiple target areas.

Financial & Operational Considerations

While the press release focuses primarily on technical results, the company's 100% ownership of the Angilak Uranium Project provides full exposure to any future resource development. The project's location in Nunavut, Canada, positions it within a stable mining jurisdiction with established regulatory frameworks and infrastructure considerations typical of northern Canadian mining projects.

The systematic approach to exploration, with electromagnetic modeling guiding drill targeting, suggests efficient capital allocation toward the highest-priority targets. The company's ability to achieve significant discoveries with relatively few drillholes demonstrates the effectiveness of this technical approach.

For Investors

ATHA Energy's latest results from the Angilak Uranium Project represent a significant milestone in the company's exploration efforts, delivering what management characterizes as the best exploration hole to date. The discovery of 26.3 meters of composite uranium mineralization at RIB North, combined with the extension of the mineralized corridor to 12 kilometers total length, suggests the potential for a substantial uranium resource.

The geological characteristics of the mineralization, which management believes are analogous to major Athabasca Basin deposits, provide additional confidence in the discovery's significance. For investors considering ATHA Energy, the combination of systematic exploration success, expanding mineralized corridors, and favorable uranium market dynamics presents a compelling investment thesis in Canada's emerging uranium sector.

The company's technical achievements, coupled with its 100% project ownership and systematic exploration approach, position it as a potentially significant player in Canada's uranium exploration landscape. However, investors should note that these remain early-stage exploration results, and significant additional work will be required to advance the project toward resource definition and potential development.
