Tectonic Metals Intersects 1.46 g/t Au over 26 metres within Broader Zone of 0.69 g/t Au over 125 metres in First 2025 Drill Hole at Chicken Mountain, Flat Gold Project, Alaska

The November 26, 2025 press release announces the first assay results from the 2025 drill program at the Chicken Mountain target, part of the Flat Gold Project in Alaska. The highlight intercept is from hole CMD25-011, which returned 1.46 g/t gold over 26 metres within a broader mineralized zone of 0.69 g/t gold over 124.97 metres, starting from surface. Other significant intercepts reported include 0.79 g/t gold over 51.15 metres in hole CMD25-014.

CEO Tony Reda stated these results justify their ambitious exploration strategy and reinforce the project's potential as a future open-pit, heap-leach gold mine. He noted that assays are pending from 69 more holes at Chicken Mountain alone, and these results will be used to form the foundation of a maiden resource estimate and a Preliminary Economic Assessment (PEA). The company also announced a "Virtual Drill Core Shack" webcast for December 3, 2025, to provide further geological insights.

The news is material and positive as it provides the first assay data from the extensive 18,372-metre 2025 drill program and validates the company's geological model for a bulk-tonnage, open-pit, heap-leach system at Chicken Mountain.

• Confirmation of Thesis: The reported grades (e.g., 0.69 g/t over 125m) are not spectacular on their own, but they are economically significant for a heap-leach scenario. For context, the successful Fort Knox mine in Alaska profitably processes grades around 0.30 g/t Au. These results, demonstrating wide intercepts of consistent mineralization starting at surface, are precisely what is needed to build tonnage for a large-scale, low-cost operation.

• Progression and De-risking: Tectonic had a transformational 2025, beginning with the Alpha Bowl discovery in March (65.5m of 1.2 g/t Au), followed by a 1-for-10 share consolidation, and raising approximately $34 million from strategic investors like Crescat Capital. The first result from the 2025 program was from Alpha Bowl in September (41.15m of 2.23 g/t Au), which confirmed higher-grade potential. This current news from Chicken Mountain complements the Alpha Bowl results by demonstrating the project's scale and bulk-tonnage potential. It delivers on the company's stated plan and begins to provide the data necessary for the promised maiden resource estimate.

• Expectations: The market has been anticipating the flow of drill results following the completion of the massive drill program announced on November 12. This initial release meets expectations for a bulk-tonnage target and provides confidence that the subsequent 100+ pending assays will continue to build out a significant mineralized footprint.

The results are not a "game-changer" in the sense of a new high-grade discovery, but they are a crucial and successful step in the methodical process of de-risking the project and advancing it toward an initial resource. This confirmation of grade, thickness, and continuity provides a solid foundation for the stock and justifies the significant capital raised during the year.

Tectonic Metals Inc. is a Canadian-based gold exploration company focused on advancing its district-scale Flat Gold Project in Alaska. The project is located in the Kuskokwim mineral belt, 40 km from the 39-million-ounce Donlin Gold Project. Tectonic's strategy is to define the bedrock source of the 1.4 million ounces of historical placer gold produced in the Flat district. The company is targeting a large, bulk-tonnage, open-pit, heap-leachable gold deposit, similar in style to Kinross's Fort Knox mine. The project benefits from its location on land owned by Doyon, Ltd., a major Alaskan native corporation and a key shareholder in Tectonic.
