Transformational $34M Capital Raise in 2025 Fuels Rapid and Aggressive Two-Phase Drill Campaign Positioning Flat for Growth Toward a Maiden Mineral Resource Estimate and Year-Round Operational Capacity

VANCOUVER, November 12, 2025 - Tectonic Metals Inc. ("Tectonic" or the "Company") (TSXV:TECT)(OTCQB:TETOF) today announced the successful completion of Phase Two drill program marking 2025 as the most technically ambitious exploration program to date at the Company's flagship Flat Gold Project ("Flat") in southwestern Alaska - a transformational 18,372 m, 125-hole campaign that represents the largest and most cohesive drilling effort in the project's history.

The 2025 field season, which concluded in late October, saw Tectonic execute a rapid expansion from a single-phase program to a comprehensive two-phase, multi-rig operation - fuelled by exceptional investor demand that raised $33.9M and enabled the Company to accelerate its path toward defining what management believes could become a tier-one, free-milling, heap-leachable gold system in one of North America's most prolific gold districts.

THE OPPORTUNITY: SCALE AND A SHARED VISION

Flat spans 99,840 acres of predominantly Native-owned land belonging to Doyon, Limited, one of Alaska's largest Native Regional Corporations and Tectonic's second-largest shareholder - creating a uniquely aligned partnership that streamlines project advancement, community engagement and permitting pathways.

Located near Donlin Gold - one of the world's largest undeveloped gold deposits recently designated a FAST-41 high-priority infrastructure project by the U.S. government(a federal program providing mandatory schedule certainty and coordination for complex permitting)¹ - Flat is rapidly emerging as a compelling value proposition in the same mineral belt by offering:

• Free-milling gold with multiple processing scenarios

• Chicken Mountain amenable to heap leachability with gold recoveries up to 96%²

• Potential for low-capital, low-energy development pathway

• Interpreted bedrock source of >1.4 million ounces of historic placer gold³

• Over 3 kilometres of drilled mineralized strike to a vertical depth in excess of 300 m

• Exploration upside - Six intrusion related gold targets

• Proven Leadership Team: Tectonic's leadership brings a demonstrated record of disciplined execution across exploration, development, permitting, and operations - collectively responsible for multiple successful discoveries, project advancements, and corporate transactions, including the $520M transformation and sale of Kaminak Gold Corp.⁴. This is a team that has consistently built value and delivered returns.

2025 FIELD SEASON HIGHLIGHTS

• Capital Raised: $33.9M (vs $20.5M targeted)

• Total Metres Drilled: 18,372 m

  • Phase One: 7,718 m (vs 7,000 m budgeted)

  • Phase Two: 10,654 m (vs 9,000 m budgeted)

• Total Drill Holes: 125 (Phase One: 48, Phase Two: 77)

• Objectives: Discovery, expansion drilling along strike and at depth, resource delineation and metallurgy

• Targets Tested: Alpha Bowl, Chicken Mountain, Golden Apex, Black Creek and Jam.

• Assay Results: All Phase One and Two samples have been received by the accredited analytical facilities. Assays are subject to Tectonic's quality assurance and quality control protocols and expected to be reported sequentially. While we are currently experiencing lab delays, our intention is to issue drill results in a meaningful and contextual manner in the coming weeks and months.

• Budget: Final reconciliation pending; program tracking at or below budget

• Advancing Year-Round Capability: Camp operated from May through October; infrastructure improvements are progressing toward full winterization and eventual continuous operation.

• Labour: 4,476 person days, consisting of 53,712 person hours

• Safety: Zero Lost Time Injuries (LTI's)

• Environmental: Zero reportable spills or incidents

Tony Reda, Co-Founder, President & CEO of Tectonic Metals, commented:

"The 2025 season was a defining moment for Tectonic. We set out with a bold plan at a time when market conditions suggested it couldn't be done. Yet through disciplined execution, collective resilience, and a relentless commitment to our company and the belief that Flat has what it takes to become a tier-one mining opportunity, we raised $34 million and delivered the largest and most cohesive drill program in the history of Flat - and we did it in remarkably short order."

"This was not luck. It was the outcome of a clear vision, a strong strategy, and a team that executes and refuses to settle for average. From mobilizing a third drill rig in real time, to expanding and winterizing camp infrastructure, to shifting Flat to year-round operational capacity, to completing more than 18,000 metres of drilling safely and efficiently, our team demonstrated what is possible when great people rally around a shared purpose. Flat has never been a drill play. This is a mining play. Game on. I am incredibly proud of what we achieved in 2025 and even more energized by what lies ahead."

PHASE ONE ACHIEVEMENTS

Tectonic's 2025 Phase One program (7,718 m in 48 holes) delivered strong initial results at Alpha Bowl, with hole CMR25-035 intersecting 2.23 g/t Au over 41.15 m, including 4.00 g/t Au over 21.34 m with 13.25 g/t Au over 4.57 m. This hole represented a significant 250-metre step-out from the 2024 Alpha Bowl discovery hole, confirming the system remains open in multiple directions and validating the presence of high-grade gold mineralization at scale.

PHASE TWO ACHIEVEMENTS

Phase Two was strategically designed to:

• Wheeled loader to facilitate offloading and loading of aircraft

• Hard sided core-cutting building, 2 additional electric core saws and generator

• New core logging facility, existing core logging tent converted to RC processing facility

• New, larger office tent, existing office tent moved and converted to sleeper

• Additional small sleeper tents

• An additional 5 TransCube?Contract?fuel?tanks to bring total bulk fuel storage to 11,000 gallons

• Additional 220-gallon double wall helicopter portable fuel tanks

• Acquired grader to support airstrip snow removal and drill road construction, enabling rapid mobilization for the 2026 drill program

STRONG INVESTOR RESPONSE FUELS RECORD DRILL CAMPAIGN

Tectonic's ability to rapidly scale from a single-phase program to a full two-phase, multi-rig campaign was powered by exceptional investor demand:

• April 2025: Initial $7M financing, anchored by $5M+ from Crescat Capital, institutions, and long-term, supportive shareholders⁵

• May 2025: Financing oversubscribed by 80%, closing at $12.7M⁶

• July-August 2025: Additional financings raised $21.2M (vs. $13.5M targeted), with new strategic support from VanEck (Vaneck Global Gold Fund and VanEck International Investors Gold Fund) and Franklin Templeton (Franklin Gold and Precious Metals Fund) ⁷

Total 2025 capital raised:~$33.9M

OPERATIONAL EXCELLENCE

The completion of Phase Two, involving nearly 54,000 person hours, without incident or work-related injury, is a testament to the skill and dedication of our carefully curated operations team, contractors, and vendors, whose exemplary efforts to ensure a safe and successful continuation of drilling into the fall 2025 season have primed the Company for success in 2026.
