Tectonic Metals Drills 9.94 g/t Au over 36.58 meters including 15.73 g/t

Au over 22.86 metres with 104.23 g/t Au over 3.05 meters at Chicken

Mountain, Flat Gold Project

364 Gram-Metre Near-Surface Drill Intercept Anchors New High-Grade Corridor

Assay Results Pending from 34 Additional Drill Holes Across Multiple Targets

VANCOUVER, BC / ACCESS Newswire / January 22, 2026 / Tectonic Metals Inc. (“Tectonic” or the

“Company”) (TSX-V:TECT)(OTCQB:TETOF) today announced additional drill assay results from the

Company’s flagship 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), see Figure 1. 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.

CEO Commentary

"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.”

"And 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.”

Key Geological Achievements and Characteristics

1. 364 Gram-Metre Bonanza Intercept Anchors a New Interpreted Higher-Grade Corridor, see

Figure 3 and 4.

• CMR25-084: 104.23 g/t Au over 3.05 m within 15.73 g/t Au over 22.86 m, all within 9.94

g/t Au over 36.58 m

• Represents the highest gram-metre intercept reported to date at Chicken Mountain

• Hole ended in mineralization at 54.86 m, indicating down-dip and along -strike expansion

potential.

2. 100% Drill Success Rate

• 176 of 176 holes intersected gold mineralization (100% success)

• 108 of 176 holes (61.4%) ended in mineralization

• Mineralization begins at or near surface along entire 3 km of strike length

3. Significant Resource Expansion Potential

• Chicken Mountain, including Alpha Bowl and Adit Zones, demonstrates over 3.0 km x 1

km x 400 m of potential mineralized strike, width and depth.

• Multiple higher-grade corridors identified; see below.

• Mineralization remains open at to the south, north, east, west and at depth. The depth is

constrained only by drill depth, not by geological boundaries.

• Early r esource delineation drilling demonstrates continuity and predictability of the

mineralized envelope

o Five drill sections on a ~200 m x ~75 m spacing executed with all drill holes collared

in mineralization

• Diamond drilling on the central Chicken Mountain section confirms multiple mineralized

intervals and corridor to at least ~230 m vertical extent, with mineralization continuing to

>300 m downhole in deeper holes (e.g., CMD25-027).
