GEIGER MOBILIZES FOR 10,000-METRE DRILL PROGRAM AT ABERDEEN PROJECT IN THE THELON BASIN

Geiger Energy Corp. has launched preparations to begin a 10,000-metre summer drill program in June on the Aberdeen project, Thelon basin, Nunavut.

Key highlights

• 10,000-metre summer drill program set to commence in June at the Aberdeen project in Nunavut's Thelon basin;
• Program designed to target high-grade unconformity-related uranium mineralization at Loki and expand the high-grade Tatiggaq discovery;
• Loki hosts the first uranium mineralization intersected at the unconformity in Thelon basin sandstone, along with extensive alteration similar to major Athabasca-style systems;
• Tatiggaq remains open along strike and at depth, with systematic stepouts planned to test scale and continuity;
• Exploration will focus on identifying the structural controls and alteration systems associated with high-grade uranium deposition;
• Successful drilling has the potential to further establish the Thelon basin as an emerging world-class uranium district.

The 2026 program will focus primarily on the Loki and Tatiggaq target areas, where prior drilling and exploration have confirmed strong uranium fertility, extensive alteration and encouraging mineralization. At Loki, Geiger has intersected the first uranium mineralization at the unconformity within Thelon formation sandstone at relatively shallow depths, alongside a large alteration system analogous to those associated with major Athabasca basin uranium deposits. At Tatiggaq, the company is advancing a high-grade basement-hosted uranium discovery that remains open for expansion.

Targeting will focus on identifying key structural traps that have led to alteration and uranium enrichment, in hopes of uncovering the first true high-grade uranium intersection in the Thelon basin. Tatiggaq is already a high-grade prospect that only requires systematic drilling to determine the size and extent of the mineralization.

"The objective of the program is clear, to vector toward and discover high-grade uranium mineralization. The Thelon basin is the last major undeveloped high-grade uranium play in the world. Orano's known undeveloped deposits (Kiggavik project) and Geiger's high-grade, shallow Tatiggaq and Qavvik prospects demonstrate the region's fertility and prospectivity. Our strategy is to show further that the Thelon basin is the next major world uranium play through discovery and advancement of our known assets and, if successful, a serious rerating of the region is anticipated," said Dr. Rebecca Hunter, president and chief executive officer of Geiger.

Aberdeen project overview

Geiger plans to explore the Loki and Tatiggaq areas in 2026 aggressively. The Loki area hosts the first intersections of uranium mineralization in the Thelon formation sandstone at the unconformity and extensive alteration of the sandstone column, which is analogous to what is observed above high-grade deposits in the Athabasca basin. Targeting will focus on stepouts along the four km gravity anomaly, first near the known alteration and enrichment areas. Tests along the north end of the anomaly will be a priority, as they are likely to host the main controlling structures. The uranium enrichment of the sandstone column is compelling and requires several drill holes to test and hone in on the most prospective areas.

The Tatiggaq prospects are a high-grade basement-hosted zone consisting of two pods over a 300-metre area. The extent of the 1.5-kilometre gravity anomaly that hosts the Tatiggaq prospect remains open to testing along strike and at depth. In 2024, a new showing (up to 0.79 per cent U3O8 (triuranium octoxide) over 0.1 m) was discovered within the gravity anomaly to the north of the Tatiggaq prospect and also requires follow-up. Systematic stepouts are planned along the main uranium-hosting east-northeast-trending fault trend to delineate additional pods and stepouts to the north to follow up the 2024 new showing. Tatiggaq is located five km west of Orano's Andrew Lake deposit and is a key asset to develop to complement the known basement-hosted uranium resources in the area.

Numerous other showings and untested anomalies are also present on the Aberdeen project and will be evaluated and considered for testing in 2026, depending on results and available time and budget.

To begin the company's preparations winter overland hauling has been organized to start immediately. Winter overland hauling is a key aspect of exploration in the Thelon basin, as it is a very cost-effective and low-impact method of hauling exploration-related supplies (such as fuel, drills, drill equipment and consumables) to the company's camp site on Aberdeen Lake. The company deploys a convoy of snow-tracked vehicles with sleighs that carry loads from Baker Lake to the site, which takes around two to three days per convoy. The prime hauling months are March, April and parts of May, depending on weather conditions.

About Geiger Energy Corp.

Geiger controls approximately 390,000 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 km 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.
