Geiger's Aberdeen Drill Programme Returns Uranium Enrichment Across All Four Priority Targets

• Uranium enrichment intersected in 7 of 9 drill holes at the Loki target, with values locally reaching up to 111 ppm
• First confirmed uranium at the unconformity horizon in the northeast Thelon Basin
• All four priority targets, Loki, Bjorn, Tarzan, and Lobster, returned alteration and geochemical signatures consistent with uranium mineralising systems
• Alteration patterns at the Tarzan grid are comparable to those observed at the company's Tatiggaq and Qavvik deposits
• A total of 5,300 metres drilled across the 2025 programme, with multiple targets identified for follow-up drilling

Geiger Energy Corp. (TSXV: BEEP; OTCQB: BSENF) is a Canada-based uranium exploration company with land holdings in two established uranium regions: approximately 390,000 hectares in Saskatchewan's Athabasca Basin and 95,519 hectares in Nunavut's Thelon Basin. Its flagship Aberdeen Project hosts the Tatiggaq and Qavvik high-grade discoveries, both basement-hosted systems that remain open along strike and at depth, alongside more than 50 additional priority targets. In the Athabasca Basin, Geiger is advancing the Hook Project, home to the near-surface ACKIO discovery, which extends over 375 metres along strike and remains open in multiple directions.

Uranium Enrichment at Loki, Including First Confirmed Uranium at the Unconformity in the NE Thelon Basin

The Loki target returned uranium enrichment above background levels in 7 of 9 drill holes across a nearly 4-kilometre gravity anomaly, where sandstone cover is less than 175 metres thick. For context, background uranium in sandstone is typically below 1 ppm. Weighted-average uranium values across several holes ranged from approximately 1 to 2.75 ppm over intervals of 120 to 152 metres, with peak values reaching 77.7 ppm and 111 ppm over shorter sections.

Three holes recorded uranium enrichment directly at the unconformity, the geological boundary between basement rock and overlying sandstone where high-grade uranium deposits commonly occur. Intersections included 119 ppm over 0.6 metres, 43.1 ppm over 0.7 metres, and 6.4 ppm over 6.8 metres. According to the company, this is the first time uranium has been confirmed at this horizon in the northeast Thelon Basin.

Supporting the uranium results, lead isotope ratios returned anomalous readings across all Loki holes, with one hole showing an anomaly spanning nearly 140 metres. Anomalous lead isotope ratios indicate the presence of radiogenic lead, which forms through the decay of uranium. Additional indicators include widespread clay alteration, bleaching, sulphide minerals, and elevated trace elements including molybdenum, nickel, cobalt, and boron.

President and CEO Rebecca Hunter noted:

"This type of enrichment has not previously been documented in the Thelon Basin and materially upgrades the regional potential for major unconformity-style uranium deposits."

Multi-Target Results Across the Bjorn, Tarzan, and Lobster Grids

At Bjorn, two holes tested a gravity and magnetic low anomaly extending more than 3 kilometres along the Thelon Fault. Both holes intersected extensive alteration through sandstone and conglomerate, and one returned above-background uranium of up to 3.13 ppm between 152 and 197 metres in strongly altered rock. The anomaly remains largely untested, with the two 2025 holes covering only a portion of its extent.

At Tarzan, four holes were drilled along a northeast structural trend that also hosts Orano's Kiggavik deposits. Peak uranium values of 155 ppm and 345 ppm were recorded in two holes, coinciding with boron values up to 1,100 ppm and elevated nickel and molybdenum. The alteration signatures observed are described by the company as identical to hanging wall alteration at the Tatiggaq and Qavvik deposits. Several holes did not reach target depths due to drilling conditions, leaving the deeper portions of the anomaly untested.

At Lobster, a basement-hosted target with no overlying sandstone, two holes intersected intensely altered gneisses and fault rock with pervasive clay alteration. Boron values reached up to 1,790 ppm, and uranium values of up to 16.7 ppm were recorded. The Lobster grid is a gravity and magnetic low anomaly along the Judge Sissons Fault, and the 2025 programme is the first systematic drilling of this target following limited historical work that identified clay alteration and fault rock warranting further testing.

District-Scale Discovery Potential with Follow-Up Drilling Planned

The 2025 programme tested four separate targets across Aberdeen's 95,519-hectare Thelon Basin land package, with each returning evidence of uranium-bearing fluid activity, alteration, and structural features associated with unconformity-style uranium systems. The confirmation of uranium at the unconformity at Loki, combined with results from Bjorn, Tarzan, and Lobster, supports the company's characterisation of Aberdeen as a potential uranium district rather than a single-target project.

With more than 50 additional targets on the project, many untested or lightly drilled, the 2025 results provide a basis for prioritising future work.

President and CEO Rebecca Hunter stated:

"Consistent uranium enrichment across the entire sandstone column in every Loki drill hole is a highly significant result".

Follow-up drilling is planned at all four grids. Loki is the primary focus, with holes designed to test the extent of unconformity-hosted uranium and the broader sandstone system. Tarzan will see deeper drilling to test intervals not reached in 2025. Bjorn and Lobster will receive expanded programmes to better define the footprint of each anomaly.

Outlook

The 2025 Aberdeen drill programme confirmed uranium enrichment across all four priority targets and produced the first unconformity uranium intersection recorded in the northeast Thelon Basin at Loki. Geiger has identified follow-up drilling priorities at Loki, Tarzan, Bjorn, and Lobster for the 2026 field season, with the objective of advancing each target and further defining the extent of uranium mineralisation across the project.
