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 is focused on discovering high-grade uranium deposits across both regions.

Geiger's flagship asset, the Aberdeen project (Thelon basin), hosts the high-grade Tatiggaq and Qavvik discoveries. Tatiggaq is a basement-hosted system defined over a 300-metre strike length, with multiple steeply dipping mineralized lenses between 80 and 180 metres depth. The system remains open over a 1.5-kilometre strike length and at depth. Qavvik is a similarly styled basement-hosted discovery extending from surface to approximately 400 metres depth, open over 500 metres and at depth.

The Aberdeen project hosts 50-plus high-priority targets, many showing strong alteration and anomalous uranium from limited historical drilling, with several areas remaining completely untested.

In the Athabasca basin, Geiger is advancing the Hook project, which hosts the ACKIO near-surface uranium discovery. ACKIO extends over 375 metres along strike and 150 metres in width, with at least nine distinct uranium pods starting at 28 metres depth and continuing to approximately 300 metres. The system remains open in multiple directions. The Hook project also contains large clay-alteration systems with elevated radioactivity, highlighting additional discovery potential beyond ACKIO.

We seek Safe Harbor.
