TECTONIC METALS DRILLS NEW GOLD DISCOVERY: 65.5 METRES OF 1.2 G/T AU,

INCLUDING 6.1 METRES OF 6.0 G/T AU WITH 1.5 METRES OF 21.7 g/t AU; DRILLED

MINERALIZED STRIKE NOW 3KMS AND STILL OPEN

VANCOUVER, B.C., March 3, 2025 – Tectonic Metals Inc. (TECT: TSX -V; TETOF: OTCQB; T15B: FSE) (the

"Company" or "Tectonic") today announced a significant newly drilled gold discovery at the 1.5 kilometre

(“km”) by 0.5 km Alpha Bowl target, extending the confirmed mineralized strike length of the Chicken

Mountain gold system from 2 km to 3 km. To date, all 86 holes drilled at Chicken Mountain intersected gold

mineralization (a 100% drill success rate) and all mineralization remains open along strike and at depth. The

Chicken Mountain intrusion is one of six kilometre -scale potential gold deposits at Tectonic’s Flat Gold

Project ("Flat"). These latest assay results from the Company’s 2024 drill program further validate Flat’s

potential to be Alaska’s next tier-one gold asset.

Strategically located just 40 kilometers north-east of the Donlin Gold Project (“Donlin”) — a 39 million ounce

gold deposit1 jointly owned by Barrick Gold Corporation (GOLD: NYSE; ABX: TSX) and NOVAGOLD Resources

Inc. (NG: TSX; NG: NYSE) — Flat is the next most advanced gold asset in this established tier-one gold district.

Notably, Donlin’s owners recently announced a USD $43 million exploration budget for 20252, highlighting

the continued investment and confidence in the advancement of this gold project and region.

Tony Reda, President & CEO of Tectonic Metals, commented: "Alpha Bowl is an exciting new drilled gold

discovery and a game-changer for our Flat Gold Project. Tectonic’s maiden drilling confirms gold

2

mineralization in every hole, with assays reaching up to 67 g/t Au, underscoring the exceptional tenor of this

system. The scale of Alpha Bowl is extraordinary - spanning 1.5 km by 0.5 km and extending the Chicken

Mountain gold system’s strike length to 3 km and open. What also excites us is that we have now confirmed

the bedrock source responsible for the 650,000 ounces of historic placer gold shedding from this area — an

extraordinary feat given that this drilling was our first attempt and conducted in a geologically blind

environment at relatively shallow depths. If we can delineate such a compelling gold discovery with limited

RC drilling, one can only imagine what a deeper, more systematic diamond drill campaign could unveil. We

are merely scratching the surface of what could be the most transformative development in the history of

the Flat Gold Project."

Peter Kleespies, Vice President Exploration of Tectonic Metals, stated: “The 2024 exploration drill program

results continue to demonstrate the scale of the Flat Gold system and potential for uncovering a significant

gold resource at the property. The results from the Alpha Bowl drilling are especially encouraging, and

evidence of a continuously mineralized intrusion-related gold system extending over 3 kilometres is

beginning to emerge. Furthermore, the relationship between low magnetic susceptibility zones and

intrusions identified by recent Tectonic 3-D inversion of magnetic data has been validated in areas of no

bedrock exposure and presents an excellent exploration vectoring tool for blind to surface discoveries as we

continue to explore the extent of mineralization at the six intrusion targets identified at the property. The

time has clearly come to expand our efforts at Flat to fully realize the resource potential of the mineralization

identified to date but also to continue to make new discoveries as we deepen our geological understanding

of the overall Flat gold system.”

Tectonic Alpha Bowl Drilling Discovers Bedrock Gold Source Underlying 650,000 Oz of Historic Placer

Gold Production3

• First-Ever Drilling of Alpha Bowl, Host to One of Alaska’s Most Prolific Placer Creeks: In over 40

years of sporadic, limited hard rock exploration at the Flat Gold Project, Tectonic is the first

company ever to drill the Alpha Bowl target, host to Flat Creek. With over 650,000 ounces of

recorded historical placer gold production3, Flat Creek is the most prolific placer gold producing

creek at the Flat Gold Project, heralded as the third richest placer mining jurisdiction in all of Alaska

with over 1.4 million ounces of recorded placer gold production.

• High Tenor Gold Successfully Drilled in a Geologically "Blind" Target: all drill holes were collared

in or near extensive historic placer and regolith mining areas—zones where gold has eroded from

its original lode source and accumulated in weathered soil and rock layers. These areas have

undergone significant surface disturbance, leaving little to no available surficial geological

information. Despite these challenges, Tectonic successfully intersected gold mineralization in all

five Alpha Bowl drill holes by targeting a largely "blind" anomaly. This achievement underscores the

strong gold potential of Alpha Bowl and validates the effectiveness of Tectonic’s exploration

approach.

• Confirmed Bedrock Gold Source for Flat Creek Placers Located at Alpha Bowl: Tectonic 2024 drill

results combined with other geological evidence compiled by Tectonic, confirm that the bedrock

gold source for the prolific historic Flat Creek Placers is present and located within intrusive rocks

beneath the historical workings in the Alpha Bowl.

• 2024 Drilling Confirms High-Tenor, Nuggety Gold Linked to Flat Creek’s Bedrock Source; see Figure

2.0 Drill Assay Table Below: 2024 Alpha Bowl drilling revealed instances of high gold tenor and

coarse gold distribution, closely associated with increased quartz veining. The 2024 drill results are

consistent with a 1992 Alaska Department of Natural Resources & United States Geological Survey

report4 that described "gaudy gold-quartz veining" observed by historical placer miners in the upper

stripping (i.e. surface lode mining) at Flat Creek which is vastly different than the finer, "oatmeal

flake-sized" gold found in other Chicken Mountain placer drainages. This further supports the

conclusion that Tectonic has identified the bedrock source of Flat Creek’s historic placer gold

endowment.

Alpha Bowl Drill Highlights

• 100% Drill Success Rate: all five holes intersected significant gold grades.

• Comprehensive Sampling Enhances Accuracy of 2024 Drill Assays: Given the coarse gold believed to

be present at Alpha Bowl and potentially elsewhere at Chicken Mountain, Tectonic prioritized

maximum geological understanding and rigorous QA/QC (Quality Assurance/Quality Control) for many

of the 2024 drill holes, and more specifically for the Alpha Bowl discovery hole, CMR24-026. To ensure

the most accurate representation of gold distribution, Tectonic elected to assay all available drilled

material, particularly in zones where higher-grade assays were returned, conducting Photon Assay of

up to five unique 500 gram RC splits. While this approach resulted in a lengthier assay turnaround, it

provided the most comprehensive and precise assessment of the mineralization, reinforcing

confidence in the target’s deposit potential.

• High-Grade Assay Results Confirm Coarse, Nuggety Gold at Alpha Bowl: Demonstrating the coarse,

nuggety gold nature of mineralization at Alpha Bowl, one of five assay RC splits (see Figure 2.0)

returned:

▪ 65.53m at 2.13 g/t Au, including:

▪ 18.29m at 5.93 g/t Au

▪ 6.10m at 17.41 g/t Au

▪ 1.52m at 67.18 g/t Au

• Tectonic presents the higher-grade results (65.53m at 2.13 g/t Au, including 18.29m of 5.92

g/t Au) to illustrate the coarse nature the gold at Alpha Bowl. These exceptional grades

reinforce Tectonic’s confidence in the Alpha Bowl system, suggesting the presence of

bonanza-grade zones and a higher gold value per tonne—both critical factors in enhancing

4

the economic potential of a deposit.

+ Refer to Figure 1 for the reported average grade derived from assaying up to five unique 500g sample splits. Figure 2 represents one of the 5 sample

splits and is presented to illustrate the coarse nature of gold distribution at the Alpha Bowl discovery .

The assay results reported above are from a second 500g sample split. All widths are interval widths as insufficient data exists currently to determine

true zone widths. Select composites utilizing 0.10, 0.30 or 0.50 g/t Au cut-off with a maximum 3.1m continuous (two sample) below cut-off inclusion.

• All five holes collared and ended in gold mineralization delineating a 250m x 200m mineralized area

down to a maximum vertical depth of 100 m or 128 m drill hole length. Mineralization is open for

expansion in all directions.

• 3 kms of drilled mineralized strike: the southernmost drill hole at Alpha Bowl is over 800m from

nearest Chicken Mountain drill collar location (DDH97-02CM), which intersected 4.57 g/t Au over

7.01m With the completion of the 2024 drilling at Alpha Bowl, the total length of mineralized drilled

strike at Chicken Mountain is over 3 km and remains open along strike and at depth.

• Northern extension of Chicken Mountain: all holes intersected intrusive rocks from collar. RC chip

microscopic examination and four acid multi-element geochemistry assaying of RC chips indicate that

the intrusion intersected at Alpha Bowl is identical to the intrusive phase (quartz-biotite syenite)

present at Chicken Mountain and represents the northern extension or “nose” of the Chicken

Mountain intrusion, typically a very prospective location for higher-tenor gold mineralization in these

types of systems.

• Multigenerational veining and overprinting can lead to grade enrichment and is consistent with gold

mineralization typically found at the nose of the intrusion. Alpha Bowl appears to have an abundance

of quartz veining, shearing and structural deformation mineralization coinciding with

5

multigenerational veining and multiple mineralizing events potentially resulting in overprinting and

grade enrichment.

• Low magnetic susceptibility validated as a powerful exploration tool: Drilling at Alpha Bowl

specifically targeted a zone of low magnetic susceptibility zone based on the observed relationship

between zones of low magnetic susceptibility and favourable intrusions with gold mineralization

identified by recent Tectonic 3-D inversion of magnetic data. With the Alpha Bowl discovery, this

approach has been validated in areas of no bedrock exposure and is now a validated exploration

vectoring tool for identifying areas of gold mineralization, and more specifically, blind to surface

discoveries. At Flat, the low magnetic susceptibility zone is over 8 km in length and 2.5 km in width

starting beyond the very south end of the Chicken Mountain intrusion, extending through Alpha Bowl

and northward into Golden Apex.

2024 Chicken Mountain Drill Highlights and Key Findings:

• 12 holes drilled and reported herein along 1100m of strike down to a maximum 152.40m drill hole

length.

• 100% Drill Success Rate Continues: 86 holes drilled to date at Chicken Mountain and all 86 holes

intersected gold mineralization

• Mineralization Remains Open at Depth, Limited Only by Drill Penetration: The depth of

mineralization appears to be limited only by drill penetration, as 46 out of 86 drill holes to date have

ended in mineralization. The deepest drill hole on record drilled by Tectonic in 2023 extends 428.5m

in length to a vertical depth of 325m, indicating the potential for significant mineralization at greater

depths yet to be fully tested.

• Expansive 3 kilometres of Mineralization Validating Bulk Tonnage Open-Pit Mining Opportunity:

The drill results reported herein extend the total strike length at Chicken Mountain to 3 km, with

mineralization starting at surface with little to no overburden extending to a vertical depth of 325m.

Chicken Mountain remains open in all directions, offering significant expansion potential with

relatively easy additional drilling, further validating the opportunity for a large-scale, bulk-tonnage

open-pit mining operation.

• Heap Leachable Mineralization: Most holes intersected oxide gold mineralization hosted in

leucrocratic quartz monzonite, same host rock used in Tectonic’s recent heap leach column tests,

which yielded 96% and 91% gold recoveries using coarse ¾ inch crushed material of mixed oxidized

and non-oxidized fresh rock.5 Heap leaching is one of many gold extraction methods amenable to the

mineralization at Chicken Mountain. The average grade of many heap leach mines throughout the

world is 0.51 g/t Au6, and more notably, Kinross Gold Corporation (TSX: K, NYSE: KGC) Fort Knox Mine

in Alaska processes 0.30 g/t Au profitably7.

The Flat Gold System – Alaska’s Next Tier 1 Opportunity

The Flat Gold Project spans 99,800 acres of predominantly Native-owned land belonging to Doyon Limited,

one of Alaska’s largest Native Regional Corporations, which has invested over $4M in Tectonic Metals,

endorsing exploration on their land. Flat hosts bulk -tonnage, intrusion -related gold mineralization,

comparable to the Fort Knox gold mine. It is recognized as a prime example of the direct relationship

between placer gold and bedrock sources. Placer gold shed from intrusions has led to 1.4 Moz of placer gold

production. Notably, the project has achieved a 100% drill success rate to date, with gold intersected in all

86 drill holes at Chicken Mountain.

The analytical work for the 2024 Flat drilling program was performed by MSA Labs (MSA) an internationally

recognized and accredited analytical services provider, which is independent of Tectonic. All RC chip

samples were submitted to MSA’s Prince George, British Columbia facility where the entire sample was

dried, crushed as required and riffle split into 500 g subsamples for analysis (prep code CRU-CPA). Sample

splits were then analysed for gold using PhotonAssayTM (CPA -Au1). A second 500 g split was take n and

analyzed for gold using PhotonAssayTM (CPA-Au1) for select holes and up to 3 additional 500 g splits were

taken for select samples and analyzed for gold using PhotonAssayTM (CPA -Au1). The assays from each

sample for which multiple splits were analyzed were combined for the final reported values.

QA/QC procedures for the drill program included insertion of a certificated reference material every 20

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 Prince

George, British Columbia.
