Tectonic Metals Drilling Transforms Alpha Bowl from Discovery to Emerging Large-Scale Resource Growth Opportunity: 820 m * 600 m * 400 m Gold Footprint Defined

The news release dated January 15, 2026, announces that drilling at the Alpha Bowl target has defined a significant mineralized footprint of 820m x 600m x 400m. Critically, this drilling has successfully connected Alpha Bowl to the Chicken Mountain target, establishing over 3 kilometers of continuous gold mineralization. The company reports a 100% drill success rate (134 for 134 holes intersecting gold) across the Flat Gold Project. Notable intercepts include hole CMD25-015, which returned 74m at 0.85 g/t Au (including a high-grade 0.65m interval of 25.16 g/t Au with visible gold). The system remains open in all directions.

The impact is Material - Positive for the following reasons: - Scale Validation: Connecting two major zones into a single 3km strike length significantly increases the potential for a large-scale, bulk-tonnage resource. This moves the project from isolated discovery toward a cohesive district-scale deposit. - Hit Consistency: A 100% success rate across 134 holes is statistically significant, suggesting high continuity of the mineralizing system, which reduces geological risk for a future Resource Estimate. - Depth Potential: Defining a 400m vertical footprint at Alpha Bowl indicates the system is not just a thin surface veneer but has volume. - Strategic Momentum: This confirms the "Game Changer" financing from November 2025 was deployed effectively to prove scale. However, the grades (mostly sub-1 g/t) reinforce that this is a bulk-tonnage, heap-leach play rather than a high-grade underground target, making it sensitive to gold prices and capital expenditure for infrastructure.

Tectonic Metals is focused on the Flat Gold Project in southwestern Alaska, approximately 40km from the 39Moz Donlin Gold Project. The project is situated on land owned by Doyon, Limited, an Alaska Native Regional Corporation. The flagship Flat project is interpreted as a Reduced Intrusion-Related Gold System (RIRGS), characterized by bulk-tonnage, free-milling mineralization. Tectonic's goal is to prove a tier-one open-pit, heap-leach opportunity similar to Kinross’s Fort Knox mine.
