The significant clay alteration systems share similarities with deposit areas in the Athabasca Basin (e.g. the Millennium Deposit), which hosts a significant clay alteration halo outboard of the main deposit area. The presence of these two distinct alteration systems at TT and TAB kilometres from the ACKIO discovery shows the project area is fertile for more uranium mineralization discoveries.

The Hook Project is a key asset for Geiger as it hosts significant uranium mineralization at ACKIO, and the TT and TAB areas have now displayed additional prospective hydrothermal systems. The overall objective of the 2026 drill program is to further test these systems at TT and TAB and determine if there is a another mineralized zone in the area. Finalization of the drill program will evolve in the coming weeks as we compile and review the historical data and recent drilling result with our technical team. For the 2026 program, all the drill and camp logistics as well as staffing are organized and will be ready for deployment in early February.

About Geiger

Geiger holds approximately 390,000 hectares of exploration ground in the Athabasca Basin of northern Saskatchewan, Canada, and an additional 95,519 hectares in Nunavut's Thelon Basin. The Company's exploration strategy is focused on discovering high-grade uranium deposits within these two prolific uranium districts.

Geiger's primary asset, the Aberdeen Project in the Thelon Basin, Nunavut, hosts the high-grade Tatiggaq and Qavvik uranium discoveries.

• Tatiggaq is a basement-hosted prospect defined over a 300-metre strike length, comprising multiple steeply dipping, ENE-trending mineralized lenses situated between 80 and 180 metres depth. Notable drill intercepts include 2.25% U3O8 over 11.1 metres¹, underscoring the high-grade potential of the system. The system is open for expansion over a 1.5 km strike length and a depth.

• Qavvik is a similarly styled, basement-hosted prospect characterized by steeply dipping, mineralized ENE-trending lenses across a 100 x 100 metre area, extending from surface to approximately 400 metres depth. The system is open for expansion over a 500 metre area and at depth.

• The Aberdeen Project contains over 50 high-priority exploration targets, many of which exhibit strong alteration and anomalous uranium from limited historical drilling - while several remain completely untested.

In the Athabasca Basin, Geiger is advancing its Hook Project, which hosts the ACKIO near-surface uranium prospect.

• ACKIO is a basement hosted prospect that extends for more than 375 metres along strike and 150 metres in width. It consists of at least nine distinct uranium pods with mineralization beginning at depth of 28 metres and continuing to approximately 300 metres. The system remains open at depth and along strike to the north, south, and east, highlighting significant potential for expansion.

• Significant massive clay alterations systems with elevated radioactivity are also present within the Hook Project that show promising mineralization potential outboard of the ACKIO discovery.
