Unconstrained Growth Potential: 3.3 km Drilled Mineralized Strike x 700 m Width x 300 m Vertical Depth and Remaining Open in All Directions

100% Drill Success Continues: 191 of 191 Drill Holes Intersecting Gold Mineralization

VANCOUVER, BC / ACCESS Newswire / February 5, 2026 / Tectonic Metals Inc. ("Tectonic" or the "Company") (TSXV:TECT)(OTCQB:TETOF) today announced final assay results from the 2025 drill program at Chicken Mountain. Today's results delivered thick, at or near-surface intercepts that reinforce Chicken Mountain as a bulk-tonnage, heap leachable Reduced Intrusion Related Gold System ("RIRGS") within the Company's flagship 99,800-acre Flat Gold Project ("Flat") in Southwest Alaska.

The 2025 drilling program has successfully advanced Chicken Mountain from an exploration target into a kilometre-scale resource growth opportunity, expanding the continuously mineralized footprint and delineating higher-grade corridors that may support potential starter-pit development scenarios.

Tectonic plans to resume drilling in early May 2026, and additional metallurgical test work is now underway, including 2-inch crush heap-leach column tests to investigate the viability of run-of-mine ("ROM") gold processing. A more detailed news release outlining the Company's 2026 plans and objectives is expected to be announced in the coming months.

CEO Commentary

"Chicken Mountain demonstrates a combination of scale, continuity and favorable metallurgy in a bulk-tonnage gold system. Unlike narrow vein deposits that rely on selective mining, this style of mineralization has the potential to support simpler, straightforward open-pit development, with broad, continuous zones that begin at surface and remain open in all directions."

What differentiates Chicken Mountain is the convergence of three key value drivers. First, scale: we've defined approximately 3.3 kilometres of mineralized strike to date, with widths approaching 700 metres, while drill testing only a fraction of the mapped intrusive complex. Second, predictability: a 100% drill success rate across 191 holes demonstrates a fertile and strong mineralizing system that can be targeted effectively. Third, metallurgy: previously reported heap-leach recoveries of up to 96%, together with ongoing work evaluating run-of-mine potential, point to a processing profile with meaningful capital and operating advantages."

"Within this large mineralized, envelope, we've identified multiple higher-grade corridors that could represent potential mining starter-pit opportunities. Beyond the intrusion itself, the hornfelsed sedimentary rocks surrounding Chicken Mountain represent an additional, untested and underexplored opportunity. At Black Creek, located 6 km away, drilling intersected 4.50 g/t Au over 48.77 m with 7.79 g/t Au over 24.38 m hosted in hornfels - the same prospective host rock that surrounds Chicken Mountain."

"As we move forward, our focus is clear: continued step-out drilling to define the ultimate scale of the Chicken mountain RIRGS system, advancing metallurgical work toward a potential run-of-mine flowsheet, and progressing toward a maiden mineral resource estimate. Each of these workstreams is aimed at systematically de-risking Chicken Mountain while preserving its significant growth potential."

Assay results from 16 drill holes are reported herein - 9 diamond core holes and 7 reverse circulation ("RC") holes - representing approximately 3,535 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 central area of the Chicken Mountain intrusion. All assay results from the Companies 2025 drill program are now reported.

2025 Drilling Successfully Transitions Chicken Mountain from Exploration Target into a Multi-kilometre Gold Resource Growth Opportunity

1. Scale & Continuity: Chicken Mountain is interpreted as a Reduced Intrusion-Related Gold System hosted within a receptive monzonitic intrusive complex. Drilling has defined a mineralized envelope measuring 3.3 km in strike, up to 700 m in width, and extending to 300 m vertical depth, see figure 1 and 2.

Multiple drill holes intersect ~275 m of continuous gold mineralization starting at surface and indicating a coherent body of mineralized rock, see figures 5 and 6.

While drilling to date has defined a significant envelope of mineralization, the broader Chicken Mountain system extends well beyond current drilling:

• Geophysical intrusive footprint: ~6.5 km × 6.0 km

Untested Hornfels Target: The Chicken Mountain intrusion is surrounded by hundreds of metres of hornfels, a baked sedimentary rock that commonly hosts gold in intrusion-related systems. This prospective host rock remains entirely untested at Chicken Mountain but has been validated at Tectonic's Black Creek intrusion target, located 6 km from Chicken Mountain, where recent drilling intersected 4.50 g/t Au over 48.77 m, including 7.79 g/t Au over 24.38 m (see January 29, 2025, news release) confirming the fertility of hornfels units at Flat.

• Results reported from two drill fences L1 (4 core holes) and L2 (6 RC and 4 core holes) drilled across the Chicken Mountain intrusion.

• Width of mineralization envelope along both drilled sections is 700 m.

• Core drilling on both sections confirms mineralization to 300 m vertical depth and remains open.

• Multiple holes ended in mineralization (see Tables 1 and 2), supporting potential for down-dip and along-strike expansion.

Results Summary

A summary of the results released today for the 7 RC holes are presented by drill section in Table 1, and a summary of the 9 core results are presented in Table 2. Data pertaining to locations of drill holes included in the announcement are presented in Table 3.

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.
