HOLE AT CHICKEN MOUNTAIN, FLAT GOLD PROJECT, ALASKA
Initial 2025 Chicken Mountain Drill Assays Confirm Grade, Thickness, Continuity
and Scale; Reinforcing A Bulk-Tonnage, Open-Pit, Heap Leach RIRGS Opportunity
VANCOUVER, B.C. – November 24, 2025 – Tectonic Metals Inc. (“Tectonic” or the “Company”) (TSX-
V: TECT; OTCQB: TETOF) today announced the initial assay results from 10 of the 79 holes
drilled during the 2025 drill campaign at Chicken Mountain – a bulk -tonnage, open -pit, heap -
leachable gold opportunity and one of six kilometre-scale intrusive centres at the Company’s
flagship ~99,800 acre Flat Gold Project (“Flat”) in southwestern Alaska.
The Chicken Mountain intrusion (6.5 x 6.0 kilometres) is the largest and
most geologically understood intrusive center at Flat and widely recognized as the primary lode
source of the 1.4 million ounces of placer gold historically mined from the surrounding drainages.1
To date, the 2025 drill campaign represents the largest and most comprehensive program ever
completed at Flat, totaling 18,373 metres (“m”) drilled across 125 holes, including 10,780 m in 79
holes at Chicken Mountain.
The ten drill holes reported today account for just 1,811 m – approximately 17% of the total 2025
drilling at Chicken Mountain. Assay results from a further 114 drill holes across Chicken Mountain,
Alpha Bowl, and other intrusive centres are pending and wi ll be released as they are
received, validated, and incorporated into the Company’s geological model.
2025 DRILLING STRATEGY & HIGHLIGHTS – CONTINUITY, EXPANSION & RESOURCE DELINEATION
AT CHICKEN MOUNTAIN
The 2025 Phase One and Phase Two drilling programs were strategically designed to accelerate
Chicken Mountain toward resource readiness by extending mineralization along strike and at
depth, validating historical information, tightening geological and stru ctural
controls, generating two-inch coarse -crush metallurgical samples for heap -leach column
testing and collecting a comprehensive dataset required for 3D resource modelling and future
engineering studies.
Definition of vectors to higher grade mineralized zones will be assisted by data collected and
interpreted from orientated drill core measurements, characterization of alteration assemblages,
vein geometry, vein density and quantitative assessment of mineralization styles.
Tectonic also utilized reverse-circulation (“RC”) drilling to rapidly test for shallow, near -surface
mineralization and extend mineralization across strike.
Together, these objectives underpin the project’s progression from exploration drilling toward
formal resource delineation and future economic assessment.
DRILL HIGHLIGHTS FROM FIRST TEN HOLES (FIVE DIAMOND, FIVE REVERSE CIRCULATION)

KEY TAKEAWAYS
1. 100% Drill-Hit Success Rate Continues
• 96 of 96 holes drilled to date and each drill hole has intersected gold mineralization
• 53 of 96 holes ended in gold mineralization, mineralization remains open at depth and is
only constrained by drilled depth – not geology
2. A Bulk-Tonnage, Open-Pit, At Surface and Vertically Extensive Gold System is in Play
• 3 km of mineralized strike length starting at surface
• Vertical extent now confirmed to >350 m, up from 325 m, and remains open in all
directions
3. Accelerating Toward Resource Definition
• Chicken Mountain continues to establish itself as the primary and fastest path toward a
maiden resource estimation at Flat
• Extensive, continuous zones of gold mineralization with emerging and clearly defined
higher-grade domains; demonstrates the potential for high-margin mining starter -
pits warranting targeted follow-up drilling
4. Geological Characteristics Consistent with RIRGS Models
• Alteration, geometry, and grade distribution are consistent with Reduced Intrusion-
Related Gold System (RIRGS) models, including notable similarities to Kinross Gold
Corporation (TSX: K, NYSE: KGC) Fort Knox Mine in Alaska
5. Economic Heap Leaching Processing Potential – A Competitive Advantage
• Four large-diameter metallurgical holes (PQ core) successfully drilled broad zones of gold
mineralization confirming or exceeding expectations and producing high -quality coarse-
crush material for two-inch crush heap leach column testing
• Drill holes intersected oxidized to partially oxidized quartz monzonite, consistent with
lithologies used in prior metallurgical test work
• Previously announced heap-leach column tests on ¾ inch coarse crushed mixed oxide/fresh
material yielded excellent gold recoveries of 96% and 91%
• For context, heap leaching is one of several gold extraction methods suitable for the
mineralization at Chicken Mountain. The average grade of many heap leach mines globally
is 0.51 g/t Au 2, and notably, Kinross Gold Corporation (TSX: K, NYSE: KGC) Fort Knox Mine
in Alaska processes 0.30 g/t Au3 profitably
• These metallurgical tests and results support ongoing evaluation of the potential for run-
of-mine (ROM) heap-leach processing, a potential catalyst for improved capital efficiency,
lower operating costs, and enhanced project economics

Metres Across 125 Drill Holes at Flat Gold Project, Alaska
Tony Reda, Co-Founder, President & CEO of Tectonic Metals, commented:
“These latest results both justify and motivate our ambitious exploration strategy at Chicken
Mountain. Big targets merit big programs, and w ith over 10,000 metres of drilling at Chicken
Mountain alone and assays pending from 69 holes, we are only at the very front edge of what this
system can reveal.
As more assays come in, they will refine grade, continuity, geometry and starter-pit potential –
and ultimately form the foundation of Flat’s maiden resource estimate and PEA. What excites me
most is that everything we are seeing points to a real opportunity for a future open-pit, heap-leach
gold mine in one of Alaska’s great gold districts.”
