Chicken Mountain & Audit Zone Report On Completed Drill Holes

VANCOUVER – Tectonic Metals Inc. reported on 11 drill holes completed during the 2025 drill campaign at Chicken Mountain and the Adit Zone, located within the ~99,800 acre Flat Gold Project in Southwest Alaska. The 11 drill holes (9 reverse circulation (RC) and 2 diamond core) reported herein represent approximately 1,460 m of drilling from the Company’s 18,373 m, 125-hole, 2025 drill program across the Flat Gold Project. All drill holes intersected gold mineralization, with 10 of the 11 holes ending in mineralization, maintaining Tectonic’s 100% drill-hit success rate at Flat. The RC fence of drilling announced today intersects a 550-metre-wide mineralized section that remains open in all directions highlighting the potential of the Adit Zone.

Assay results from 103 additional drill holes are currently pending and expected to be reported in Q1 2026. Tectonic will provide further updates as results are received and interpreted.
