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

Alpha Bowl Drilling Now Connects to Chicken Mountain, Establishing > 3 km of Continuous Gold Mineralization: Open in all directions & Reinforcing Flat as a Large, Bulk-Tonnage, Open-Pit RIRGS Tier-One Mining Opportunity

Assay Results Pending from 76 Additional Drill Holes Across Multiple Targets

VANCOUVER, BC / ACCESS Newswire / January 15, 2026 / Tectonic Metals Inc. ("Tectonic" or the "Company") (TSX-V:TECT)(OTCQB:TETOF) today announced additional assay results from 24 drill holes completed during the 2025 drill campaign at Alpha Bowl, located within the Company's flagship ~99,800 acre Flat Gold Project ("Flat") in Southwest Alaska.

The 24 drill holes reported herein - 9 diamond core holes and 15 reverse circulation ("RC") holes - represent approximately 4,800 metres ("m") of drilling from the Company's 18,373 m 2025 program. All holes intersected gold mineralization, returning grades of up to 25.16 g/t Au (see assay table below), with 14 holes collaring in mineralization and 10 holes ending in mineralization, including the diamond drill hole CMD25-015, drilled to a depth of 392 metres.

These results confirm geological and mineralized continuity between Alpha Bowl and Chicken Mountain, establishing a gold system extending more than 3 kilometres along strike that remains open at depth and in all directions. Drilling continues to expand and define Alpha Bowl as a coherent three-dimensional mineralized body measuring approximately 820 metres along strike, 600 metres in width, and extending to at least 400 metres depth.

Alpha Bowl: From Blind Target to Volumetrically Significant Gold System in 12 Months

Alpha Bowl represents a significant exploration success and highlights the gold resource potential that Flat can deliver with systematic drilling. Prior to 2024, this target had never been drill tested in the history of the Flat Gold Project, despite hosting Flat Creek, one of Alaska's richest placer producing creeks with over 650,000 ounces of recorded placer gold production¹.

Alpha Bowl is primarily blind to surface with limited to no outcrop exposure or direct surface expression. Through systematic geological interpretation, geophysical targeting and strategic drilling, Tectonic executed a drill program in 2024 yielding a brand-new discovery of 1.22 g/t Au over 65.53 m , including 6.01 g/t Au over 6.1 m with 21.72 g/t Au over 1.52 m (see Tectonic News Release, March 3, 2025).

Follow up 2025 step-out drilling on this discovery hole returned 2.23 g/t Au over 41.15 m , including 4.00 g/t Au over 21.34 m (see News Release, September 10, 2025), testing the eastern edge of the target where mineralization remains wide open.

In less than twelve months, Alpha Bowl has evolved from a blind drill target into a volumetrically significant gold system. The confirmed connection to Chicken Mountain establishes a district-scale mineralized corridor at Flat, reinforcing the project's potential as a large, bulk-tonnage, reduced intrusion-related gold system ("RIRGS") and supporting continued systematic drill expansion.

Key Geological Achievements and Characteristics:

1. Validated Geological Continuity Over 3 Kilometers of Drilled Mineralized Strike

Alpha Bowl is now confirmed via drilling as the northern extension of the Chicken Mountain intrusion, creating a continuous, coherent, 3-kilometer mineralized corridor from Chicken Mountain through the Adit Zone to the Alpha Bowl Zone. This continuity is fundamental to resource estimation and for consideration during the preliminary resource estimation study planned for late 2026.

2. Exceptional Drill Success Rate Validates Scale, Strength of The Chicken Mountain / Alpha Bowl System

• 134 out of 134 holes (100%) have intersected gold mineralization

• Mineralization begins at or near surface (critical for open-pit economics)

• 73 of 134 holes (54.5%) ended in mineralization, indicating the system extends beyond current drill penetration

• Mineralization remains open at depth and is constrained only by drill depth, not by geological boundaries

This extraordinary hit rate is rare in exploration and demonstrates that Tectonic's geological team has developed a solid understanding of the mineralizing system. This significantly de-risks future drilling and resource expansion.

3. Alpha Bowl Significant and High-Grade Gold Intercepts to Date

While the system demonstrates bulk-tonnage potential, the presence of higher-grade intervals warrants infill and expansion drilling and presents the opportunity for multiple higher-grade starter pits that could significantly enhance project economics. These higher-grade intervals are not considered as random, current analysis models them with structural controls and fluid focusing mechanisms within the broader mineralized system. Examples of these higher-grade intervals at Alpha Bowl include new results released today and previously reported intervals:

CMD25-015

• 25.16 g.t Au over 0.60 m (5 flecks of visible gold observed), within
  1.36 g/t Au over 39.00 m, all within
  0.85 g/t Au over 74.00 m
  Diamond drill hole ending in mineralization; total hole length 392.28 m

CMR25-045

• 1.56 g/t Au over 10.67 m, within
  0.55 g/t Au over 73.15 m

• RC drill ending in mineralization; total hole length 94.49 m

CMD25-009

• 1.07 g/t Au over 14.80 m, within
  0.48 g/t Au over 94.00 m

CMR25-068

• 15.41 g/t Au over 1.26 m, within
  1.76 g/t Au over 13.00 m

• 10.28 g/t Au over 1.0 0m, within
  3.81 g/t Au over 3.00 m

CMR25-042

• 12.48 g/t Au over 1.52 m, within
  1.29 g/t Au over 16.76 m
  RC drill hole ending in mineralization; total hole length 110.34 m

CMR24-026 (previously announced)

• 21.72 g/t Au over 1.52 m, within
  6.01 g/t Au over 6.1 m, all within
  1.22 g/t Au over 65.53 m
  RC drill hole ending in mineralization; total hole length 65.32 m

CMR25-035 (previously announced)

• 4.00 g/t Au over 21.34 m, within
  2.23 g/t Au over 41.15 m

4. Substantial Resource Growth Potential Remains at Alpha Bowl

• Percentage of Target Tested: Approximately 60% of the interpreted target, with mineralization depth constrained only by current drill hole length

Critical Growth Vectors:

1. Higher Grade Gold Concentration in Eastern Alpha Bowl: 3D geological modeling of recent drill assays combined with structural, alteration, and geochemical vectors demonstrates that gold tenor at Alpha Bowl increases in the eastern portion of the bowl, suggesting the core of the system may be situated to the east of the current drilling and remains open to drill testing. See Figure 4 (below) and Alpha Bowl Video.

2. Grade Enhancement: Higher-grade intervals occurring within broader mineralized envelopes indicate strong potential for additional high-grade shoot discovery through continued testing of the structural framework and systematic infill drilling.

3. Strike Extension (North): Pending drill assays testing an additional 500 m of strike potential could extend the defined mineralized corridor to 1.3+ km at Alpha Bowl alone, representing a nearly 60% increase in the zone's along-strike footprint.

4. Depth Extension: 54.5% of holes ended in mineralization, indicating strong potential for resource expansion below 400 m depth.

5. Width Expansion: The 600 m width represents the tested extent; however, the intrusive body is interpreted to continue laterally well beyond current drill coverage

5. Classic RIRGS Characteristics Throughout the System

Alpha Bowl exhibits textbook Reduced Intrusion-Related Gold System (RIRGS) characteristics, directly comparable to world-class deposits including the Fort Knox Mine operated by Kinross Gold Corporation in Alaska (9+ million ounces produced, continuing operation²):

6. Validating a Prolific Gold System

Alpha Bowl hosts one of Alaska's most productive placer gold creeks, with over 650,000 ounces of recorded historic placer production ¹ . This extraordinary placer endowment provides independent validation of the potential gold inventory within the Alpha Bowl intrusion. The source of this placer gold is now being delineated in bedrock through systematic drilling.
