GEIGER HITS AGAIN AT APOLLO: SECOND HOLE INTERSECTS 45 METRES OF SHALLOW URANIUM MINERALIZATION STARTING AT 40 METRES DEPTH, 100 METRES ALONG STRIKE ON THE KIGGAVIK TREND

Geiger Energy Corp.'s follow-up hole to its grassroots Apollo uranium discovery at the Aberdeen project in the Thelon basin, Nunavut. The second hole at Apollo, a 100-metre stepout to the southwest, hit again, intersecting 45 metres of elevated radioactivity starting at approximately 40 metres depth, shallower than in the discovery hole (see news release dated Sept. 14, 2026).

Key highlights

• Apollo hits again: APL26-002 intersected 45 metres of elevated radioactivity from approximately 40 to 85 metres depth, 100 metres along strike from the discovery hole. Alteration and sporadic radioactivity continue to approximately 240 metres.
• Closer to surface: The main radioactive interval begins at approximately 40 metres depth, shallower than in the discovery hole, showing the system extends toward surface.
• Same fault, same signature as Fox: APL26-002 hit the same altered breccias and Andrew Lakefault structure seen at Fox and extending onto Orano's Kiggavik project.
• District scale: Fox and Apollo sit 10 kilometres apart along approximately 17 kilometres of the Andrew Lake fault on Geiger ground. Only one of Apollo's three gravity anomalies has been drilled, with 50-plus targets across Aberdeen.
• Key aspect: Apollo hit again, 100 metres away and closer to surface. It now joins Fox as Geiger's second growing discovery on the Kiggavik fault trend.
• Geiger's objective is to prove that the Thelon is the premier uranium basin. It is less explored, shallower and cheaper to test target by target. Orano's Kiggavik asset has already validated the basin, while Geiger controls a true district-scale position with substantial discovery upside still ahead.

"Our second hole at Apollo did exactly what we needed: it hit again, it hit shallower and it showed the system continues," said Dr. Rebecca Hunter, president and chief executive officer of Geiger Energy. "Fox and Apollo sit 10 kilometres apart on the same fault that extends onto Orano's Kiggavik project, and we have drilled only a small piece of it. We are no longer looking at isolated drill holes -- we are beginning to see the outline of a new uranium district."

Apollo now joins Fox, where the third hole returned high-grade radioactivity (see news release dated Sept. 21, 2026), as two growing discoveries ten kilometres apart on the Andrew Lake fault, the structure that extends onto Orano's Kiggavik project. Both were previously undrilled targets, and both returned uranium mineralization in their first drill holes.

Apollo hits again, closer to surface

Drill hole APL26-002 intersected one main zone of elevated radioactivity from approximately 40 to 85 m depth (45 m). Readings within this zone largely exceed 70 counts per second (background is 40 to 50 cps), with abundant intervals over 100 cps and localized readings of up to 180 cps in drill core. The downhole probe recorded counts of up to 402 cps, approximately eight times probe background, in the most broken and clay-altered part of the fault, where core recovery was poor. The strongest radioactivity coincides with the zone of core loss, so the probe captures radioactivity the recovered core does not fully reflect. Sporadic elevated radioactivity and strong alteration continue to approximately 240 m depth. Beyond 240 m, moderate alteration continues to the end of the hole at 313 m.

The strongest radioactivity occurs within intensely clay-altered and hematized, non-cohesive breccias, with sporadic to pervasive bleaching and sooty sulphides. Elevated uranium appears to be associated with weakly disseminated uranium mineralization within the hematized breccias and along clay-hematite altered interfaces. This alteration overprints an older, quartz-stockwork-rich fault zone similar to that observed at Fox and interpreted to form part of the Andrew Lake fault structure. Follow-up drilling will step into the footwall of the fault to test for the potential continuation and strengthening of the uranium mineralized system. The mineralization systems in the area such as Tatiggaq and Qavvik tend to focus along the northwest side of these master northeast- to east-northeast-trending faults.

Andrew Lake fault: a fertile uranium corridor

Apollo and Fox occur along the Andrew Lake fault, the major structural corridor that extends from Orano's Kiggavik area onto Geiger's Aberdeen project. The Kiggavik-area deposits collectively contain a historical estimate of approximately 127.3 million pounds U3O8 (triuranium octoxide) in the indicated category and approximately 5.4 million pounds U3O8 in the inferred category.

The Andrew Lake fault extends approximately 17 kilometres across Aberdeen through Fox and Apollo. Both discoveries are characterized by strong structural disruption, clay and hematite alteration, bleaching and uranium mineralization associated with reactivated fault and breccia systems.

A proven model and next steps

The success at Fox and Apollo provides Geiger with an important validation of its exploration model at Aberdeen. Both targets were generated using the same combination of structural interpretation, gravity, magnetic and geological data, and both produced uranium discoveries in their first drill holes.

Geiger's next phase of exploration will define the size of the Apollo and Fox systems, including drilling into the footwall of the fault at Apollo, while testing the two undrilled Apollo gravity anomalies and additional targets along the Andrew Lake fault and across Aberdeen. Assay results from Fox and Apollo are expected later in the year, and the next drill program is planned for early June, 2027.

About Geiger Energy Corp.

Geiger controls approximately 338,000 hectares in Saskatchewan's Athabasca basin and 95,519 hectares in Nunavut's Thelon basin, two of the world's most prospective uranium districts. The company's flagship Aberdeen project (Thelon basin) hosts the high-grade, basement-hosted Tatiggaq and Qavvik discoveries -- both shallow systems open along strike and at depth -- together with more than 50 high-priority targets, many showing strong alteration and anomalous uranium from limited historical drilling. In 2026, Geiger made two new grassroots uranium discoveries at Fox and Apollo, both previously untested targets on the Andrew Lake fault. In the Athabasca basin, Geiger is advancing the Hook project, host to the near-surface Ackio uranium discovery, which comprises at least nine mineralized pods beginning at 28 metres depth and remains open in multiple directions.
