Tectonic Metals Drills 272 Metres of 0.50 g/t Au and 277 Metres of 0.49 g/t Au; Confirms Bulk-Tonnage Potential at Heap-Leachable Chicken Mountain, Flat Gold Project, Alaska

The most recent news release (February 5, 2026) provides final assay results from the 2025 drill program at the Flat Gold Project, specifically the Chicken Mountain target. The highlights include exceptionally long, continuous intercepts: 272 metres of 0.50 g/t Au (Hole CMD25-031) and 277.55 metres of 0.49 g/t Au (Hole CMD25-028). Crucially, the company reports that these entire drill holes were mineralized from top to bottom. Tectonic has achieved a 100% drill success rate for the program, with all 191 holes (18,373m) intersecting gold mineralization. This has defined a mineralized envelope 3.3 km in strike length, 700 m in width, and 300 m in depth, which remains open in all directions.

This news is a material positive development that transitions the project from a series of high-grade "pockets" into a coherent, massive bulk-tonnage system. - Scale and Continuity: Defining a 3.3km strike with "entire hole" mineralization significantly de-risks the project's volume potential. While the grades (0.50 g/t) are low, they are consistent with profitable bulk-tonnage heap-leach operations like Kinross’s Fort Knox. - 100% Hit Rate: A perfect success rate across 191 holes is statistically rare in gold exploration and suggests a very robust and pervasive mineralizing system. - Metallurgy: Previous news indicated 96% recoveries in heap-leach tests. The broad, near-surface nature of this mineralization supports a low strip-ratio, open-pit, heap-leach model. - Expansion: The connection between Alpha Bowl and Chicken Mountain indicates that the separate targets are likely part of a single, massive intrusive complex.

Tectonic Metals is focused on the Flat Gold Project in Alaska, located 40km from the 39Moz Donlin Gold Project. The property is approximately 100,000 acres of predominantly Native-owned land (Doyon Ltd.). The project targets Reduced Intrusion-Related Gold Systems (RIRGS), similar to Fort Knox and Snowline Gold’s Valley discovery. The Chicken Mountain target is the flagship, characterized by a large monzonite intrusion with documented historical placer gold production of 1.4 million ounces in the district.
