TECTONIC METALS LAUNCHES LARGEST DRILL PROGRAM TO DATE

WITH THREE DRILL RIGS AT FLAT GOLD PROJECT, ALASKA

VANCOUVER, B.C., June 02, 202 5 – Tectonic Metals Inc. (“Tectonic” or the “Company”) (TSX -V: TECT;

OTCQB: TETOF) today announced the official launch of the 2025 Phase One multi -rig drill pr ogram – the

largest drill program in history at the Company’s flagship Flat Gold Project (“Flat”) in southwestern Alaska.

Located on 99,840 acres of predominantly Native-owned land belonging to Doyon, Ltd. (“Doyon”), one of

Alaska’s largest Native Regional Corporations and Tectonic’s second -largest shareholder . The Flat Gold

Project is emerging as a tier-one, free-milling and heap leachable gold mining opportunity near one of the

largest undeveloped gold deposits in the world, the Donlin Gold Project. The Company also announces the

grant of stock options to key Tectonic team members.

Tony Reda, Co-Founder, President & CEO of Tectonic Metals, commented : “We are entering the most

transformative phase yet at Flat. With two rigs on site and a third en route, our 2025 Phase One drill

campaign is laser-focused on delivering maximum value per metre drilled – through discovery, strategic de-

risking and setting the stage for an economic mining opportunity at Flat.

Our primary focus is Alpha Bowl – a high-grade, near-surface oxide discovery that is not only open in all

directions but directly linked to over 650,000 ounces of historic placer gold production.1 This is our strongest

indication yet that we are drilling into the heart of a fertile gold system. From there, we advance to Golden

Apex, our highest-priority untested intrusion target. If we unlock additional metres, we have our sights set

on other district-scale intrusion targets that may see their first-ever drill holes.

What sets Flat apart isn’t just its scale or geology, but its early, credible demonstration of multiple mineral

processing pathways – including heap leaching and the rare , highly coveted potential for run -of-mine

processing. With that endgame in mind, we are reverse engineering what a future mine at Flat could look

like, which is why we are collecting two-inch crush material for additional heap leach column testing while

at the same time targeting higher-grade corridors that could underpin high-margin starter pits.

I would like to emphasize that Phase One is just the beginning. As Flat continues to reveal its tier-one scale

potential, we anticipate ongoing drilling in the months and years ahead. The project is rich with untapped

targets, and we have a clear roadmap for continuous growth.”

Peter Kleespies, Vice President of Exploration, commented: “Last season’s Alpha Bowl discovery not only

confirmed near -surface, high -grade oxide gold mineralization but also validated our RIRGS exploration

model – specifically the association between low magnetic susceptibility zones, productive intrusion phases

and hornfelsing, and proximity to gold-rich placer drainages as key indicators of blind, intrusion-related gold

systems. The 2025 Phase One program is designed to build on that success. At Alpha Bowl, our drilling will

focus on expanding mineralization along strike and at depth, targeting structurally controlled feeder zones

and refining our geological model using oriented c ore and alteration mapping. Concurrently, we will apply

the same integrated approach – relational geochemistry, 3D magnetic inv ersion, and structural

reinterpretation – to test Golden Apex, our highest -priority undrilled intrusion target. Our 2025 program

will directly test for this intrusion with the objective of advancing Golden Apex from a compelling target to

a new discovery.”

2025 Phase One Primary Drill Target: Alpha Bowl – Discovery of the Bedrock Source Beneath One of

Alaska’s Richest Placer Creeks

Alpha Bowl has rapidly evolved from a conceptual target into a confirmed high -grade, near-surface oxide

gold discovery. Interpreted to represent the higher-grade core of the Chicken Mountain intrusive system

and the bedrock source of over 650,000 ounces of historic placer gold from Flat Creek.

The 2024 drill campaign marked the first-ever drilling at Alpha Bowl, a 1.5 km x 1.0 km shallow basin located

at the northern margin or "nose" of the Chicken Mountain intrusion. Despite a geologically blind setting –

overprinted by decades of regolith and placer mining and offering minimal surficial geological context –

Tectonic’s methodical approach led to a breakthrough discovery, drill hole CMR24-026 returned (PR March

3, 2025):

• 65.53 metres at 1.22 g/t Au, mineralized from surface to end-of-hole

o Including 18.29m at 2.22 g/t Au

o With subintervals of 6.10m at 6.01 g/t Au and 1.52m at 21.72 g/t Au

A reverse circulation (“RC”) split sample from the same hole, subjected to Photon Assay to better account

for coarse gold, returned even stronger grades:

• 65.53m at 2.13 g/t Au

o Including 18.29m at 5.93 g/t Au

o With 6.10m at 17.41 g/t Au and 1.52m at 67.18 g/t Au

This discovery confirms a high-tenor gold system with early signs of bonanza -grade potential and extends

the drilled mineralized strike of the Chicken Mountain intrusion to over 3 km, with mineralization open in

all directions and at depth.

2025 Alpha Bowl Drill Program Objectives

The 2025 campaign will focus on building upon the Alpha Bowl discovery with a series of diamond drill holes

up to 300 metres in length supplemented with Reverse Circulation (“RC”) drilling to cover the expansive

area with key objectives of:

• Establishing scale, grade and continuity of the Alpha Bowl target

• Testing for deeper, structurally controlled feeder zones – potentially the conduits of focused

mineralizing fluid pathways responsible for higher-grade mineralization and the exceptional placer

endowment in the area.

• Collecting oriented core data to refine structural interpretations and support vectoring toward

high-grade shoots

• Characterizing alteration assemblages and veining density to delineate zones of higher gold tenor

• Defining geological and structural controls within the broader Chicken Mountain system, especially

at its northern extension

Additional Value Drivers of the Phase One Drill Program

Chicken Mountain – Advancing a Large-Scale, Open-Pit Heap Leachable Reduced Intrusion Related Gold

System (“RIRGS”)

Chicken Mountain is a 6.5 km x 6.0 km monzonite intrusion with over 3 km of drilled strike and

mineralization confirmed to 325 metres vertical depth – representing a very small fraction of the entire

intrusion. Notably, every creek draining from Chicken Mountain, including Alpha Bowl’s Flat Creek, has

yielded historical placer gold – evidence of a large, gold-fertile system.

Metallurgy De-Risks Development: 96% Gold Recovery Confirms Heap Leach Viability

Tectonic’s metallurgical program – beginning with its inaugural testing results (PR February 16, 2023) and

followed by heap leach column tests (PR May 16, 2024) – has confirmed that gold mineralization at Chicken

Mountain is both free-milling and amenable to heap leaching. Initial heap leach column tests using coarse

¾-inch material from both oxidized and non -oxidized mineralized rock delivered exceptional results ,

yielding 96% and 91% gold recoveries after roughly 70 days, with over 80% recovery achieved within 29 –

36 days.

2025 Phase One Drill Program Objectives at Chicken Mountain

The 2025 drill campaign is strategically designed to generate critical technical data ahead of a maiden

mineral resource estimate and future Preliminary Economic Assessment (PEA). Key initiatives include:

• Drilling PQ core to collect 2-inch material for additional coarser crush heap leach column testing –

further validating the potential for ROM heap leaching and minimizing future crushing and grinding

requirements, which typically account for ~50% of a mine’s AISC (see slide 30 of Tectonic Corporate

Presentation-showing 1 g/t cut off long section)

4

• Targeting high-grade corridors and near surface mineralization to delineate potential high-margin

mining starter pits (see slide 25 of Tectonic Corporate Presentation -showing 1 g/t cut off long

section).

• Collecting oriented core data to refine the structural model and enhance drill targeting for high -

grade mineralization.

Golden Apex – Flat’s Most Compelling Underexplored Intrusive Gold Target with Strong Geological and

Placer Gold Linkages

Golden Apex is emerging as one of Flat’s most prospective and underexplored Reduced Intrusion -Related

Gold System (RIRGS) targets. Encompassing a 2.5 km x 2.0 km footprint, it exhibits all the hallmarks of a

fertile intrusion-related gold system, including hornfelsing, a >1 km gold -in-soil anomaly and proximity to

key structural corridors such as the Golden Apex and Black Creek faults.

Positioned immediately upstream of placer drainages with over 682,000 ounces (see slides 4, 6, 8 and 9 of

Tectonic Corporate Presentation) of recorded placer gold production. Golden Apex offers a direct vector to

a likely bedrock source.1 Limited historical drilling in 2003 (hole GA03-02) was poorly oriented and collared

into a fault zone, and yet still intercepted multiple gold-bearing intervals (PR September 5, 2024):

• 12.34m @ 1.08 g/t Au, including 1.67m @ 7.13 g/t Au

• 22.86m @ 1.00 g/t Au, including 6.70m @ 3.09 g/t Au

• 9.60m @ 0.93 g/t Au

In 2024, Tectonic re -logged the historical core, resampled key intervals, and conducted 3D magnetic

inversion modeling, which revealed the potential for a previously unrecognized, shallow blind intrusion

hosted within a low magnetic susceptibility domain – a geophysical signature that directly led to the Alpha

Bowl 2024 drill discovery and proven to be a powerful vectoring tool for blind, high-potential RIRGS targets.

In 2025, Tectonic will initiate targeted step -out diamond drilling from GA03 -02 to follow up on these

historical results and directly test for the newly interpreted causative intrusion at this highly prospective

target.

Armed with historic and new drill assay data, new geophysical modelling and a proven exploration vector,

Golden Apex now ranks as the highest-priority untested intrusion center at the Flat Gold Project and a

compelling target for discovery in 2025.
