Tectonic Metals Intersects 1.46 g/t Au over 26 metres within Broader Zone of 0.69 g/t Au over 125 metres in First 2025 Drill 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, BC / ACCESS Newswire / November 26, 2025 / Tectonic Metals Inc. ("Tectonic" or the "Company") (TSXV: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 will 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 structural 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.

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 Au2, 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

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 with 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."

Qualified Person
Tectonic Metals' disclosure of technical or scientific information in this press release has been reviewed, verified and approved by Peter Kleespies, M.Sc., P.Geo., Vice President of Exploration, who is a Qualified Person in accordance with Canadian regulatory requirements set out in National Instrument 43-101.
The analytical work for the 2025 Flat drilling program was performed by MSA Labs (MSA) an internationally recognized and accredited analytical services provider, which is independent of Tectonic. All core and RC samples were submitted to MSA's Fairbanks, Alaska facility. Certain sample shipments were shipped to MSA's Prince George, British Columbia facility to expedite analysis times. At either lab the entire sample was dried, crushed to 2mm and riffle split into nominal 500 g subsample jars for analysis (prep code CRU-CPA). Sample split jars were then analysed for gold using PhotonAssayTM (CPA-Au1). If additional nominal 500-gram PhotonAssay TM analysis splits are conducted for a given samples results from all splits are combined on a weight average basis. All initial PhotonAssay TM samples will undergo further analysis for a suite of 48 elements (IMS-230), with pulverization of jar contents to 85% passing 75um (PPU-510), with four acid digestion and ICP-MS finish.
QA/QC procedures for the drill program included insertion of a certificated reference material every 20 samples, blanks at rate of approximately every 25 samples and a field duplicate sample (split of the 1.5 m original sample) every 25 samples. All QAQC control samples returned values within acceptable limits
Samples are placed in sealed and security tagged bags and shipped directly to the MSA facility in Fairbanks, Alaska, utilizing strict Chain of Custody protocols.
