100% Drill Success Continues: 191 of 191 Drill Holes Intersecting Gold Mineralization
VANCOUVER, B.C. – February 5, 2026 – Tectonic Metals Inc. (“Tectonic” or the “Company”) (TSX-
V: 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 pot ential 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 outlin ing 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 grow th
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:
• Gold-in-soil anomaly: ~4.0 km in length
• Mapped intrusive (monzonitic) complex: ~4.5 km × 3.0 km
• 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.
2. Unconstrained Growth Potential: Mineralization remains open in all directions and is
constrained only by drilling, not geology.
3. 100% Drill Success Rate Continues: 191 of 191 Chicken Mountain holes intersected gold
mineralization.
4. 61% of all drill holes (117 of 191 holes ) ended in mineralization , including today’s reported
drill holes CMD25-021, which ended in 5.00 m of 2.45 g/t Au, and CMR25-120 which ended in
4.57 m at 1.94 g/t Au implying the ultimate depth and strike of the system have not yet been
bracketed.
5. Reduced Exploration Risk : With 100% of the drill holes intersecting mineralization, the
exploration risk regarding continuity is reduced. The system appears to be targetable, robust,
and pervasive.
6. Higher-Grade Internal Architecture: The identification of higher-grade corridors, 6 in total now
across the 3.3 kms of drilled strike , within the broader low er-grade envelope warrants drill
follow up , see figure 4 . These zones have the potential to represent, mining starter -pit
opportunities for early capex payback.
7. Two Strategic Fences Drilled and Reported Today:
• 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. Full assay results for the 7 RC and 9

Exploration Outlook 2026
Chicken Mountain/Alpha Bowl Drilling:
• Expansion and targeted drilling of six identified higher -grade corridors for grade -tonnage
optimization.
• Systematic step-out drilling to define system limits and test depth extensions.
• Infill drilling to support maiden mineral resource estimate.
Regional Target Testing:
• Follow-up expansion drilling at Black Creek (4.50 g/t Au over 48.77m ), Golden Apex and
Jam – each representing kilometer-scale intrusive targets.
• Surficial geochemical sampling across the property.
• Demonstrate Flat as a potential district-scale gold camp, not a single-intrusion story.
Technical De-Risking:
• Metallurgical optimization additional testing, including column testing, to evaluate crush
size reduction and ROM potential.
• 3D geological, geochemical, and structural modeling to refine drill targeting.
• Continued engagement with independent mineral resource and engineering groups to
advance pre-development studies.
