Flat Gold Project Bonanza-Grade Gold Intercepts

VANCOUVER – Tectonic Metals Inc. reported on the 99,800-acre Flat Gold Project in Southwest Alaska. Results are highlighted by a 364 gram-metre intercept at Chicken Mountain returning 9.94 g/t Au over 36.58 m, including 15.73 g/t Au over 22.86 m, with a bonanza-grade interval of 104.23 g/t Au over 3.05 m (hole CMR25-084). The hole ended in mineralization at 54.86 m, indicating strong down-dip and along-strike expansion potential.

Assay results from 42 drill holes are reported herein – 4 diamond core holes and 38 reverse circulation (RC) holes – representing approximately 3,950 metres (m) of drilling from the Company’s 18,373 m 2025 program. Drilling targeted step-out expansion and early-stage resource delineation in the southern portion of the Chicken Mountain intrusion.

“There aren’t many times in your career when you can announce a 364 gram-meter intercept and follow that with ‘…and by the way, the project boasts a 100% drill success across 176 drill holes,’ ” stated Tony Reda, President and CEO. “That combination is rare in exploration. Every single hole hit gold, which we believe is evidence of a very robust mineralizing gold system. Furthermore, the bonanza-grade intercept in drill hole CMR25-084 demonstrates that the Chicken Mountain system can generate high grades within mappable structural corridors.

We’re only scratching the surface…. literally. The fact that 65% of our holes ended in mineralization, including a 425-metre-long drill hole, means we’re drill-limited, not geology-limited. When you combine that depth extent with our demonstrated 3-kilometer strike length at Chicken Mountain, you start to see the scale potential here.

We’re systematically advancing toward a maiden mineral resource estimate while maintaining substantial blue-sky exploration upside across our 99,800-acre land package. With assays pending from 34 additional drill holes and aggressive drilling planned for 2026, our shareholders can expect continuous news flow and another exciting year ahead.”
