High-Grade Mineralization Extends to Bottom of Hole, Located 100 m South of the
2025 Black Creek Discovery

VANCOUVER, B.C., November 2, 2026 – Tectonic Metals Inc. (“Tectonic” or the “Company”) (TSX-V: TECT; OTCQX: TETOF) today announced assay results from six reverse circulation (“RC”) drill holes at Black Creek, highlighted by CMR26-159, which returned 2.86 grams per tonne gold (“g/t Au”) over 91.44 metres (“m”), including 5.61 g/t Au over 41.15 m and 12.94 g/t Au over 13.72 m. Located 100 m south of Black Creek’s 2025 discovery hole, CMR26-159 delivered the longest mineralized intercept to date and ended in high-grade mineralization, leaving the system open at depth.

Black Creek is one of six district-scale Reduced Intrusion-Related Gold System (“RIRGS”) targets at Tectonic’s flagship 99,840-acre Flat Gold Project (“Flat”) in southwest Alaska, U.S. Located six kilometres (“km”) north of Chicken Mountain, where a maiden Mineral Resource Estimate (“MRE”) is targeted for Q1 2027, Black Creek has delivered repeated high-grade gold intercepts within broad mineralized envelopes, demonstrating continuity of mineralization across a growing footprint and providing further evidence that Tectonic is vectoring towards a second gold system within the Flat district.

Black Creek Drill Assay Highlights:

• Longest intercept at Black Creek, ending in high-grade gold: CMR26-159 returned 2.86 g/t Au over 91.44 m from 22.86 m downhole, including 5.61 g/t Au over the final 41.15 m of the hole, with 12.94 g/t Au over 13.72 m. Mineralization remains open at depth.
• 100 m step-out from the 2025 high-grade discovery: CMR26-159 lies 100 m south of discovery hole CMR25-059 (4.50 g/t Au over 48.77 m) and 30 m south of holes CMR26-152 (5.09 g/t Au over 21.34 m) and CMR26-153 (1.89 g/t Au over 57.91 m), both of which also ended in mineralization.¹
• A different host rock expands district potential: Black Creek’s gold mineralization is predominantly hosted in hornfels, in contrast to the primarily monzonite-hosted mineralization at Chicken Mountain. Hornfels also occurs along the margins of other intrusion-related targets across Flat, including Golden Apex, Horseshoe, Jam and Caribou, as well as the margins of Chicken Mountain itself, making each a high-priority focus for future drilling.

Tony Reda, Co-Founder, President and CEO, commented:

“We could not have asked for a better start at a brand-new exploration target. In just 18 holes and 1,600 m of drilling, we have intersected gold mineralization in 17 holes, including four that have delivered significant high-grade intervals: 4.50 g/t Au over 48.77 m, 5.09 g/t Au over 21.34 m, 2.75 g/t Au over 38.10 m and, now, 5.61 g/t Au over 41.15 m. Notably, all three recent holes ended in mineralization, which raises a compelling question: how far does this higher-grade gold extend at depth?

“What makes Black Creek even more exciting is that we have tested only a fraction of the target. Drilling from both of our initial campaigns has outlined mineralization across an area of approximately 100 by 200 m and to a vertical depth of less than 200 m, within a much larger 1,500 by 700 m gold-in-soil anomaly, of which over 85% remains untested. Both sit within an even larger 1.5 by 2.5 km geophysical anomaly interpreted to represent an intrusive centre.

“As Chicken Mountain advances towards its maiden Mineral Resource Estimate and Preliminary Economic Assessment in 2027, Black Creek is emerging as another potentially significant gold centre at Flat. With high-grade gold intercepts, broad mineralized intervals and substantial ground yet to be explored, we see a compelling opportunity to further define the scale and continuity of mineralization and evaluate its potential to support a second mineral resource within the district.”

High-Grade Gold Continues to Expand at Black Creek

Tectonic’s first drilling at Black Creek in 2025 discovered high-grade gold in hornfelsed sedimentary rocks near the eastern margin of the Black Creek intrusion (see news release dated January 29, 2026). Follow-up drilling in 2026 extended the mineralized footprint, with CMR26-152 and CMR26-153 ending in mineralization (see news release dated August 25, 2026). CMR26-159 now extends high-grade gold a further 30 m south (see Figures 1, 3 and 4).

Black Creek Key Intercepts to Date

Hole	Reported	Interval	Including	Ended in Min.
CMR25-059	Jan 29, 2026	3.80 g/t Au over 57.91 m from surface	4.50 g/t Au over 48.77 m; 7.79 g/t Au over 24.38 m; 15.19 g/t Au over 6.10 m	No
CMR26-152	Aug 25, 2026	5.09 g/t Au over 21.34 m	17.34 g/t Au over 6.10 m	Yes
CMR26-153	Aug 25, 2026	1.89 g/t Au over 57.91 m	2.75 g/t Au over 38.10 m	Yes
CMR26-159	This release	2.86 g/t Au over 91.44 m	5.61 g/t Au over 41.15 m; 12.94 g/t Au over 13.72 m	Yes

Note: Downhole lengths reported; true widths not yet determined. Included intervals are nested and not additive.

The six new holes reported today provide important geological context for refining the Black Creek target. Gold mineralization is interpreted to be structurally controlled, with higher-grade zones potentially exhibiting steep dips and plunges. Additional drilling and oriented core analysis will help constrain the geometry, continuity and structural controls of these zones. In addition to CMR26-159 reported above, highlights from the five remaining holes include:

• CMR26-158 – Broad mineralization nearby: Collared 20 m west, the hole returned 0.46 g/t Au over 30.48 m from surface, including 1.23 g/t Au over 6.10 m, and a separate 0.31 g/t Au over 30.48 m.
• CMR26-157 – High-grade target remains untested: Collared 17 m east-southeast of CMR26-159, the hole returned no significant gold intersections but terminated at just 42.67 m downhole, above the depth of the high-grade interval in CMR26-159. The potential extension of this mineralization in that direction remains untested.
• CMR26-154 to CMR26-156 – Refining structural interpretation: Collared 50–110 m northwest of CMR26-159, these holes intersected predominantly lower-grade mineralization with localized higher-grade values, including 1.99 g/t Au over 1.52 m in CMR26-155. These results will help refine the geological model and guide follow-up drilling to target the potential extensions of higher-grade mineralization.

Geological Setting: A New Model for the Flat District

Host rock and mineralization style: Gold at Black Creek is hosted within altered and hornfelsed Kuskokwim Group sedimentary rocks, associated with quartz to quartz-carbonate-stibnite veining, oxidation, fracturing and intermediate to mafic dykes. This is a fundamentally different setting from the monzonite-dominant mineralization drilled at Chicken Mountain, demonstrating that gold at Flat is not confined to a single intrusion or host rock.

Structural controls: Gold occurs in both sedimentary rocks and dykes, suggesting that structure, rather than rock type, is the primary control on mineralization. Results from the 2025 and 2026 programs indicate that structures acted as fluid conduits, generating broad mineralized envelopes around higher-grade gold shoots.

A targeting vector: A modelled mafic dyke plunge associated with higher-grade gold mineralization provides a testable direction for step-out drilling (see Figure 5 long section).

District-scale implications: Hornfelsed sedimentary rocks occur along intrusion margins throughout the Flat district, including at Chicken Mountain, Golden Apex, Horseshoe, Jam and Caribou. Black Creek establishes a district-relevant exploration model in a host rock that expands the prospective area beyond intrusion-hosted mineralization alone. The emergence of significant gold mineralization at both Chicken Mountain and Black Creek supports the potential for multiple resource centres associated with the 20-km-long Flat volcano-plutonic complex.

Exploration Potential and Next Steps at Black Creek

The broader area at Black Creek has a long history of gold production. Placer mining on Black Creek and Upper Otter Creek produced approximately 450,000 ounces of gold, and a historical hard-rock mine at Black Creek reportedly produced approximately 2,707 ounces at an average grade of 12.00 g/t Au between 1925 and 1938.² This history points to a fertile gold system, although it does not establish the size or continuity of the mineralization intersected in current drilling.
 

To date, Black Creek remains largely untested. Drilling has covered only the eastern portion of a 1,500 m by 700 m gold-in-soil anomaly (see Figure 2), leaving over 85% of the anomaly untested. The gold-in-soil anomaly sits within a 1.5 by 2.5 km geophysical target, where drilling has confirmed the presence of intrusive rocks.

Follow-up exploration is prioritized to test the potential at Black Creek:

• Drill beneath the open intersections in CMR26-159, CMR26-152 and CMR26-153, and between the strongest results to establish their continuity.
• Continue to refine the spatial geometry of the high-grade mineralization with oriented diamond core drilling.
• Step out along strike and down plunge where the model identifies favourable hornfels, dyke margins and structural intersections.
• Rank new targets by integrating pending 2026 regional soil results, mapping and geophysics, including comparable intrusion-margin settings elsewhere at Flat.

Tectonic’s Near-Term Catalysts

Year-to-date through October 2026, Tectonic completed 31,000 m of drilling in 166 holes, focused mainly on resource delineation and expansion at Chicken Mountain. This release reports results from 525 m in six RC holes at Black Creek. Upcoming Company catalysts include:

• Pending assays from approximately 25,000 m in over 120 holes, mainly at Chicken Mountain, providing a steady flow of news through the remainder of 2026.
• Test results from 15 heap leach columns at Chicken Mountain.
• A Maiden MRE for Chicken Mountain targeted in Q1 2027, followed by a Preliminary Economic Assessment targeted in Q2 2027.
• 2026 regional soil sampling results to refine and prioritize targets across the Flat district, including Black Creek.

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., Chief Geological Officer, who is a Qualified Person in accordance with Canadian regulatory requirements set out in National Instrument 43-101.  

Analytical work for the 2026 Flat project drilling program was performed by ALS Global (“ALS”), an internationally recognized and accredited laboratory independent of Tectonic. On-site, core and reverse circulation samples were sealed in security-tagged bags and shipped under strict chain-of-custody protocols to the Lynden Transport logistics operator in Anchorage, Alaska, for delivery to ALS facilities in Vancouver, British Columbia.

Upon arrival at the laboratory, samples were dried, crushed to 2 mm and riffle split into nominal 500-gram subsample aliquots (prep codes CRU-31, SPL-32a). One portion was analyzed for gold using PhotonAssay™ (ALS code Au-PA01). PhotonAssay™ uses high-energy X-rays to determine gold content from a large sample aliquot, typically 500 g of crushed material. The method is non-destructive and is particularly suited to gold systems where larger sample aliquots may improve representativity. If additional nominal 500-gram PhotonAssay^TM analysis splits are conducted for a given sample, results from all splits are combined on a weight average basis. A second portion was pulverized such that 85% of the sample passed 75 µm (PUL-31) and was analyzed by four-acid digestion with ICP-MS finish for 48 elements (ME-MS61), along with aqua regia digestion with ICP-MS finish for trace levels of mercury (Hg-MS42).

Quality assurance and quality control (QA/QC) protocols included the insertion of certified reference material every 20 samples, blank samples at a rate of one in every 25 samples and field duplicate samples (split from the original 1.5 m for RC or core sample intervals) every 25 samples. All QA/QC results returned values within acceptable limits.

VANCOUVER, B.C., October 5, 2026 – Tectonic Metals Inc. (“Tectonic” or the “Company”) (TSX-V: TECT; OTCQX: TETOF) is pleased to announce the appointment of Eduard Epshtein, CPA, CA, as Chief Financial Officer (“CFO”) and Corporate Secretary, effective October 1, 2026.

Mr. Epshtein brings more than two decades of experience spanning capital markets, project development, strategic transactions and corporate finance. He joins Tectonic following a 16-year tenure as CFO of Lithium Americas Corp., where he helped build the company from an exploration-stage start-up into an NYSE-listed lithium producer with a market capitalization that exceeded US$5 billion.

His appointment comes at a pivotal stage as Tectonic advances its flagship Flat Gold Project in southwest Alaska, U.S., with a number of key catalysts ahead, including the completion of its largest-ever drill program at the end of October, a maiden Mineral Resource Estimate for the Chicken Mountain intrusion target planned for the first quarter of 2027, followed by a Preliminary Economic Assessment (“PEA”) targeted for the second quarter of 2027.

Tony Reda, Co-Founder, President and CEO, commented:

“Eduard has already helped build what we are now building at Tectonic. He has taken a resource company from exploration through development and into production and understands first-hand what each stage demands – from capital and corporate infrastructure to governance, strategic partnerships and execution. Having helped guide Lithium Americas from the TSX Venture Exchange to the TSX and ultimately the NYSE, while advancing major projects and completing significant financings and transactions, he brings experience that is directly aligned with the road ahead for our Company.

“While that experience will be valuable as we advance Flat and consider our future capital markets strategy, it is Eduard’s character that stands out most: he shares our long-term approach to building Tectonic and brings loyalty, integrity and commitment to the team. We are thrilled to welcome him.”

Proven Capital Markets and Corporate Leadership Experience

As CFO of Lithium Americas Corp. from its formation in 2007 through 2023, Mr. Epshtein helped build the company from an exploration-stage start-up with a small team into a major publicly traded lithium producer. During his tenure, Lithium Americas completed its initial public offering on the TSX Venture Exchange in 2008, graduated to the Toronto Stock Exchange in 2011 and listed on the New York Stock Exchange in 2018. He subsequently played a central support role in the separation of Lithium Americas into two independent public companies, including the NYSE listing of Lithium Argentina.

Mr. Epshtein also brings extensive experience advancing large-scale resource projects through successive stages of development. He helped advance the Cauchari-Olaroz lithium project in Argentina from exploration through construction and into production, with a design capacity of 40,000 tonnes per annum and approximately US$1 billion of construction capital. He was also involved in advancing the Thacker Pass project in Nevada from exploration into construction, including the development of a multi-billion-dollar funding strategy involving the U.S. Department of Energy and General Motors.

Throughout his career, Mr. Epshtein has executed a broad range of financings and strategic transactions, including project financing, convertible debt, at-the-market offerings, strategic investments, offtake arrangements and royalties. His experience also includes structuring joint ventures and strategic arrangements involving SQM, Ganfeng Lithium and General Motors, as well as significant M&A transactions, including the Western Lithium–Lithium Americas merger and the acquisitions of Millennial Lithium and Arena Minerals.

Beyond capital markets and project development, Mr. Epshtein brings broad public-company leadership experience. At various stages of Lithium Americas’ growth, he was responsible for financial reporting, finance, treasury, risk management, internal controls, information technology, corporate secretary functions, ESG reporting, Board support, as well as legal and human resources.

Eduard Epshtein commented:

“Tectonic has reached an exciting stage in its evolution. I have spent much of my career helping build and advance resource companies through periods of significant growth, and I see many of the same ingredients here: a compelling project, an experienced and ambitious team, a strong financial position and a clear long-term vision.

“What attracted me most to Tectonic is the opportunity to help build something meaningful and exciting. I look forward to working with Tony, the Board and the entire Tectonic team as we advance Flat and build the financial, corporate and capital markets foundation to support the Company through its next stage of growth.”

Chief Financial Officer and Corporate Secretary Transition

The Company also announces that Oliver Foeste has stepped down as the Company’s CFO and Corporate Secretary, effective October 1, 2026.

“I want to sincerely thank Oliver for his contributions over the past four years and for the partnership, counsel and friendship we have shared,” added Mr. Reda. “He helped the Company navigate a significant period of growth, including its financings, public company reporting requirements and governance. We are grateful for his contributions to Tectonic and wish him every success in the future.”

Stock Option Grant and Restricted Share Unit Grant

Separately, the Company announces the following grants under its Equity Incentive Plan.

Drilling Also Returns 0.51 g/t Au Over 118.16 Metres of Continuous Mineralization to End of Hole; Step-Out Drilling Expands Southern Mineralized Footprint by 200 Metres to 600 Metres

Assays Pending from 97 Drill Holes Representing 18,000 Metres of 2026 Drilling; Maiden Mineral Resource Estimate Targeted for Q1 2027

VANCOUVER, B.C., September 10, 2026 – Tectonic Metals Inc. (“Tectonic” or the “Company”) (TSX-V: TECT; OTCQX: TETOF) today announced the first assay results from its 2026 drill program at Chicken Mountain, the most advanced intrusion target at the Company’s flagship 99,840-acre Flat Gold Project (“Flat”) in southwest Alaska, U.S. The results from 15 drill holes totalling 2,276 metres (“m”) have expanded gold mineralization both at depth and to the south, further substantiating Chicken Mountain as a bulk-tonnage Reduced Intrusion Related Gold System (“RIRGS”), with potential for heap-leach processing.

Chicken Mountain is one of six district-scale intrusion targets currently identified at Flat and is being advanced toward a maiden Mineral Resource Estimate (“MRE”) targeted for Q1 2027.

Key Drill Results & Geological Highlights¹

The 2026 drill program at Flat has completed over 22,000 m year-to-date, with assay results from 15 holes totalling 2,276 m reported in this release. These results extend gold mineralization in two priority areas at Chicken Mountain: Central Corridor 2, one of six higher-grade corridors identified across 3.3 kilometres (“km”) of drilled strike; and the southern extension of the near-surface mineralized footprint.

• Central Corridor 2 Depth Extension to Over 300 m:
  • Diamond hole CMD26-036 returned 1.40 grams per tonne gold (“g/t Au”) over 30.00 m from 183.00 m, including 4.58 g/t Au over 4.50 m, and a separate deeper interval of 0.51 g/t Au over 118.16 m from 270.00 m to the end of the hole at 388.16 m, including 0.93 g/t Au over 19.50 m and 1.42 g/t Au over 7.50 m.
  • This area, defined as Central Corridor 2, was first described in Tectonic’s January 22, 2026 news release² with CMD25-011, which intersected 0.69 g/t Au over 124.97 m, including 1.46 g/t Au over 26.00 m, across a corridor measuring approximately 200 m strike × 150 m width × 100 m depth.
  • CMD26-036 now confirms the continuation of this zone down to over 300 m vertical depth. Central Corridor 2 remains open in all directions.
• Southern Mineralized Footprint Expanded by 200 m to 600 m in Length: Located 1.2 km south of CMD26-036, RC holes CMR26-141 and CMR26-142 expanded the drilled southern margin of Chicken Mountain by 200 m to the southwest, increasing its interpreted length in the southernmost tested area to approximately 600 m:
  • CMR26-141: 0.31 g/t Au over 25.91 m from 144.78 m, including 0.81 g/t Au over 4.57 m; hole ended in mineralization at 172.21 m.
  • CMR26-142 – southwestern step-out: 0.56 g/t Au over 38.10 m from 80.77 m, including 3.06 g/t Au over 4.57 m.
  • Together, these step-out holes confirm gold mineralization 200 m southwest of previous drilling and materially expand the drilled footprint in the southern portion of Chicken Mountain.
• Higher-grade Interval Within Broader Mineralization: RC hole CMR26-128 located in the southern mineralized footprint returned 0.71 g/t Au over 22.86 m from 59.44 m, including 6.79 g/t Au over 1.52 m; hole ended in mineralization at 111.25 m.
• Higher-Grade Corridor Characterization:
  • Currently, there are six higher-grade corridors identified within the broader mineralized envelope across the 3.3 km of drilled strike (see Figure 1). They range from 200 to 300 m in strike and up to 200 m in width, remaining open at depth. These corridors warrant further drilling (see Figure 4) and may have the potential to support future starter-pit opportunities.
  • Central Corridor 2 and the other higher-grade gold corridors are commonly associated with intense oxidization and/or sericite alteration, with a mineralized quartz and quartz-carbonate vein density of 1–3 veins per metre. These veins and alteration commonly host fine- to medium-grained arsenopyrite, pyrite and stibnite.
  • Tectonic is integrating oriented-core structural measurements with alteration, vein-density and multi-element geochemical data to refine the controls on higher-grade mineralization.
• 100% Drill Success Rate Continues at Chicken Mountain:
  • All 206 holes drilled to date at Chicken Mountain have intersected gold mineralization, demonstrating the widespread distribution of gold across the system.
  • Of these holes, 127 (over 60%) ended in mineralization, providing numerous opportunities for follow-up drilling below current hole depths.
• Chicken Mountain Growth Potential Still Remains Largely Untested:
  • Gold-in-soil anomaly, based on historical data, extends 4.0 km in length and up to 1.0 km in width.
  • Mapped monzonitic gold intrusive host rock complex measures approximately 4.5 km x 3.0 km, with a larger geophysical intrusive footprint of 6.5 km x 6.0 km.
  • More than 90% of the mapped intrusion complex remains untested by drilling.
  • The currently defined mineralized area (3.3 km strike x up to 700 m width x 300 m depth) remains open in all directions.
• Near-Term Catalysts:
  • Substantial Assay Pipeline: Assays are pending for 97 additional drill holes currently in the laboratory queue, representing nearly 18,000 m of the 2026 drill program. The majority of these holes are targeting resource delineation and infill drilling in support of the maiden MRE.
  • Drilling Continues: Five drill rigs remain active at Flat and are expected to operate through the end of the field season in late October, supporting a steady flow of assay results through year-end.
  • Regional Surface Exploration: Results from the regional soil-sampling program are pending and will help refine and prioritize exploration targets beyond the current drilled footprint.
  • Heap Leach Column Testwork: Results are pending from column-leach tests evaluating multiple crush sizes, including material crushed to two inches.
  • Completion of the maiden MRE is targeted for Q1 2027.

Tony Reda, Co-Founder, President & CEO, commented:

“Drilling at Chicken Mountain continues to answer the questions that matter at this stage: does the mineralization continue at depth, does the footprint keep growing and can higher grades recur within the broader system? These first 2026 results provide encouraging evidence on all three fronts.

“Every one of the 206 holes reported to date at Chicken Mountain has intersected gold, and over 60% have ended in mineralization. We are combining disciplined resource-delineation drilling with structural interpretation, geochemistry, environmental baseline work and geotechnical studies to evaluate Chicken Mountain’s potential as a large-scale, open-pit, heap-leach gold opportunity while substantial exploration upside remains across Flat and its other intrusion targets.”

Chicken Mountain: In Pursuit of a Heap-Leachable Bulk-Tonnage Mining Opportunity

Chicken Mountain is interpreted as a RIRGS, hosted by a monzonitic intrusive complex. Gold mineralization occurs in sericite-altered and variably oxidized monzonite containing sheeted, millimetre- to centimetre-scale quartz to quartz-carbonate veinlets. Drilling has outlined a mineralized footprint extending 3.3 km along strike, up to 700 m wide and to 300 m vertical depth (see Figure 2). Mineralization remains open in all directions.

Tectonic is using oriented-core structural measurements, alteration and vein-density observations, and multi-element geochemistry to refine the geological model, define the controls on higher-grade mineralization and prioritize follow-up drilling. This integrated work is intended to improve confidence in the geometry and grade distribution of the broader mineralized envelope and its internal higher-grade corridors.

The 15 holes reported in this release represent 2,276 m of step-out and early-stage resource-delineation drilling at Chicken Mountain. Assays remain pending from 97 additional drill holes representing nearly 18,000 m of 2026 drilling. Results from regional soil sampling are also pending and will be used to refine targets beyond the current drilled footprint. Environmental baseline, geochemical and geotechnical programs are advancing in parallel as the Company works toward its maiden MRE targeted for Q1 2027.

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., Chief Geological Officer, who is a Qualified Person in accordance with Canadian regulatory requirements set out in National Instrument 43-101.  

Analytical work for the 2026 Flat project drilling program was performed by ALS Global (“ALS”), an internationally recognized and accredited laboratory independent of Tectonic. On-site, core and reverse circulation samples were sealed in security-tagged bags and shipped under strict chain-of-custody protocols to the Lynden Transport logistics operator in Anchorage, Alaska, for delivery to ALS facilities in Vancouver, British Columbia.

Upon arrival at the laboratory, samples were dried, crushed to 2 mm and riffle split into nominal 500-gram subsample aliquots (prep codes CRU-31, SPL-32a). One portion was analyzed for gold using PhotonAssay™ (ALS code Au-PA01). PhotonAssay™ uses high-energy X-rays to determine gold content from a large sample aliquot, typically 500 g of crushed material. The method is non-destructive and is particularly suited to gold systems where larger sample aliquots may improve representativity. If additional nominal 500-gram PhotonAssay^TM analysis splits are conducted for a given sample, results from all splits are combined on a weight average basis. A second portion was pulverized such that 85% of the sample passed 75 µm, (PUL-31) and was analyzed by four-acid digestion with ICP-MS finish for 48 elements (ME-MS61), along with aqua regia digestion with ICP-MS finish for trace levels of mercury (Hg-MS42).

Quality assurance and quality control (QA/QC) protocols included the insertion of certified reference material every 20 samples, blank samples at rate of every 25 samples and field duplicate samples (split from the original 1.5 m for RC or 1.5 m for core intervals) every 25 samples. All QA/QC results returned values within acceptable limits.

Multiple High-Grade Drill Intercepts, Broad Intervals and Holes Ending in Mineralization Signal a Growing Gold System; Six Additional Drill Holes Pending

VANCOUVER, B.C., August 25, 2026 – Tectonic Metals Inc. (“Tectonic” or the “Company”) (TSX-V: TECT; OTCQX: TETOF) today reported new drill assay results from Black Creek, one of six intrusion-related district targets located within the Company’s flagship 99,840-acre Flat Gold Project (“Flat”) in southwest Alaska, U.S. The results confirm a second consecutive season of high-grade gold mineralization at Black Creek and strengthen the Company’s view that the target has the potential to emerge as a second gold intrusive centre at Flat, approximately six kilometres (“km”) northeast of the main bulk-tonnage, heap leach Chicken Mountain target.

2026 Black Creek Drill Assay Highlights

• CMR26-152: 5.09 grams per tonne gold (“g/t Au”) over 21.34 metres (“m”) including 17.34 g/t Au over 6.10 m;
• CMR26-153: 1.89 g/t Au over 57.91.c m, including 2.75 g/t Au over 38.10 m with 6.31 g/t Au over 7.62 m and 3.89 g/t Au over 6.10 m; and,
• CMD26-041: 3.26 g/t Au over 5.06m and 16.73 g/t Au over 2.20 m, including 29.91 g/t Au over 1.22 m.
• Importantly, both reverse-circulation (“RC”) holes CMR26-152 and CMR26-153 ended in mineralization, providing clear opportunities to expand the system further at depth and along strike.

Assays are also pending from six additional Black Creek drill holes, including holes that intersected prospective hornfels and mafic dykes, features typically associated with higher-grade mineralization at Black Creek and other Reduced Intrusion Related Gold Systems (RIRGS).

The latest results build on Black Creek’s initial 2025 drilling, reported by the Company on January 29, 2026¹, which returned 4.50 g/t Au over 48.77 m, including 7.79 g/t Au over 24.38 m and 15.19 g/t Au over 6.10 m. Together, the recurring high-grade results, broad mineralized intervals, large exploration footprint and improving geological model strengthen Tectonic’s view that Black Creek has the potential to emerge as a second gold intrusive centre at Flat.

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

“Our 2025 drilling established Black Creek as a compelling high-grade discovery. These 2026 results take it further, delivering multiple high-grade intercepts over meaningful widths with the system remaining open in all directions. Importantly, high-grade gold is now recurring across multiple holes and successive drill programs within the same prospective hornfelsed intrusion-margin setting. Together, these results are defining a coherent geological pattern and providing growing evidence of a potentially significant gold system.

“I have always believed that big gold systems leave big footprints. At Black Creek, drilling lies within a much larger, kilometre-scale convergence of gold-in-soil anomalies, geophysics, favourable geology and significant historical placer and lode gold production. We have tested only a small portion of that footprint, yet we are already seeing important indicators of grade and scale. Our next step is to further understand the geological controls, establish continuity and systematically test the scale of the system.

“Located six kilometres from Chicken Mountain, Black Creek is emerging as a potential second significant gold centre within Flat’s more than 20-kilometre-long volcano-plutonic complex. Its high-grade mineralization occurs in a different host rock than the monzonite-dominant mineralization at Chicken Mountain, demonstrating that gold at Flat is not confined to a single intrusion or geological setting. Black Creek is one of six kilometre-scale intrusion-related targets identified to date, collectively highlighting an opportunity that extends well beyond one potential deposit, one intrusion and one host rock.”

Black Creek: Building Evidence of a Second Gold Centre

Tectonic prioritized Black Creek for follow-up drilling in 2026 after its first-ever program at the target returned near-surface high-grade gold in hornfelsed sedimentary rock: 4.50 g/t Au over 48.77 m in hole CMR25-059, including 7.79 g/t Au over 24.38 m and 15.19 g/t Au over 6.10 m. The 2026 program was designed to test whether the 2025 drill discovery was part of a broader mineralized system.

The new drilling was successful in expanding the Black Creek system. High-grade gold has now been intersected in multiple holes and successive drill campaigns, with broad mineralized envelopes surrounding higher-grade internal intervals. Both 2026 RC holes ended in mineralization, and the deepest high-grade interval in diamond hole CMD26-041 occurs at approximately 202 m downhole, demonstrating gold mineralization through a substantial vertical range.

Broader mineralization of 0.39 g/t Au over 29.50 m, 0.66 g/t Au over 16.68 m and 0.41 g/t Au over 27.25 m was hosted in heavily fractured oxidized and non-oxidized hornfels and altered mafic dyke units with centimetre- to millimetre-scale quartz-to-quartz carbonate veining. Higher grade intervals, represented by 16.73 g/t Au over 2.22 m. were hosted within quartz-carbonate-stibnite veining. This newly intersected mineralization in the diamond drilling suggests that mineralization continues at depth from near-surface high-grade mineralization and remains open in all directions.

The Black Creek intrusion lies approximately six km northeast of Chicken Mountain within the more than 20-kilometre-long Flat volcano-plutonic complex. The target is supported by a 2.3 km by 1.5 km resistive electromagnetic anomaly and an approximately 1,500 m by 700 m gold-in-soil anomaly, providing a large exploration framework relative to the area tested by drilling to date.

The broader target area also has a substantial historical gold endowment and a long history of placer gold production, totalling approximately 450,000 ounces from Black Creek and upper Otter Creek. The historical hard rock mine at Black Creek reportedly produced approximately 2,707 ounces of gold at an average grade of 12.00 g/t Au between 1925 and 1938.^2,

The convergence of historical gold production, kilometre-scale soil and electromagnetic anomalies, and repeat high-grade bedrock intercepts signals a compelling, multi-dataset exploration vector. Drilling has tested only a small portion of that broader footprint.

Drilling Refines the Geological Model at Black Creek and Other Regional Targets, Providing Clearer Vectors to Higher-Grade Gold

The 2026 program is materially improving Tectonic’s understanding of the lithological and structural controls on gold at Black Creek and providing a vectoring framework that may be applicable elsewhere across the Flat district.

Gold is hosted principally in altered and hornfelsed Kuskokwim Group clastic sedimentary rocks and is associated with quartz to quartz-carbonate-stibnite veining, oxidation, fracturing and mafic dykes. Higher-grade intervals occur within this broader mineralized hornfels package, locally near mapped or modelled mafic dykes.

This host setting is geologically important because hornfelsed sedimentary rocks occur along intrusion margins elsewhere at Flat, including Chicken Mountain, Golden Apex, Horseshoe, Jam and Caribou. As a result, Black Creek establishes a district-relevant exploration model in a host rock that significantly expands the prospective search space beyond intrusion-hosted mineralization alone.

Updated geologic modelling is integrating lithology, hornfels intensity, mafic dykes, intrusion contacts, veining and assay data. The emerging model will be used to test whether higher-grade shoots are controlled by intrusive contacts, dyke margins, structural permeability, or the intersection of these features. Oriented follow-up drilling is required to resolve geometry and true widths.

Figure 3: Updated geological model of the Black Creek Target Area, notably updated hornfels and mafic dyke units that have been observed and characterized to host higher-grade gold mineralization.

Maggie Layman, Vice President Exploration, commented:

“The 2026 drilling is providing an important step forward in our understanding of Black Creek. The association of mineralization with hornfels, mafic dykes and intrusion contacts is helping us refine our geological model and identify priority targets for follow-up drilling.

“With mineralization remaining open in multiple directions and additional assays pending, we see a strong opportunity to continue expanding and defining not only the Black Creek system but also to apply these geological insights to other priority targets across the Flat district.”

Multiple Catalysts Ahead

Tectonic is advancing Black Creek alongside Chicken Mountain and a portfolio of kilometre-scale intrusion-related targets as part of a systematic strategy to test the full district-scale potential of Flat. Near-term catalysts and exploration activities include:

• Assays pending from six additional Black Creek drill holes, several of which intersected prospective hornfels and mafic dykes;
• Follow-up drilling below CMR26-152 and CMR26-153 and along strike to test continuity, orientation and true width;
• Integration of assay, structural, lithological and geophysical data into the three-dimensional geological model; and
• Application of the emerging Black Creek targeting model to other intrusion-margin targets across the Flat district.
• Additional assay results from Chicken Mountain are also expected as Tectonic continues expansion and resource-definition drilling toward a maiden mineral resource estimate targeted for early 2027.

Analytical work for the 2026 Flat project drilling program was performed by ALS Global (“ALS”), an internationally recognized and accredited laboratory independent of Tectonic. On-site, core and reverse circulation samples were sealed in security-tagged bags and shipped under strict chain-of-custody protocols to the Lynden Transport logistics operator in Anchorage, Alaska, for delivery to ALS facilities in Vancouver, British Columbia.

Upon arrival at the laboratory, samples were dried, crushed to 2 mm and riffle split into nominal 500-gram subsample aliquots (prep codes CRU-31, SPL-32a). One portion was analyzed for gold using PhotonAssay™ (ALS code Au-PA01). PhotonAssay™ uses high-energy X-rays to determine gold content from a large sample aliquot, typically 500 g of crushed material. The method is non-destructive and is particularly suited to gold systems where larger sample aliquots may improve representativity. If additional nominal 500-gram PhotonAssay^TM analysis splits are conducted for a given sample, results from all splits are combined on a weight average basis. A second portion was pulverized such that 85% of the sample passed 75 µm, (PUL-31) and was analyzed by four-acid digestion with ICP-MS finish for 48 elements (ME-MS61), along with aqua regia digestion with ICP-MS finish for trace levels of mercury (Hg-MS42).

Quality assurance and quality control (QA/QC) protocols included the insertion of certified reference material every 20 samples, blank samples at rate of approximately every 25 samples and field duplicate samples (split from the original approximately 1.5 m for RC or 1.5 m for core intervals) every 25 samples. All QA/QC results returned values within acceptable limits.

Cautionary Note Regarding Forward-Looking Statements, Historical Information and Visual Observations

This news release contains “forward-looking statements” and “forward-looking information” (collectively, “forward-looking statements”) within the meaning of applicable Canadian securities laws. All statements herein that are not statements of historical fact may be deemed to be forward-looking statements. Forward-looking statements are often, but not always, identified by words such as “may,” “will,” “should,” “anticipate,” “believe,” “expect,” “intend,” “plan,” “estimate,” “potential,” “target,” or similar terminology, or that events or conditions “may” or “will” occur.

Forward-looking statements in this release include, but are not limited to, statements regarding: the potential for mineralization at Tectonic’s projects; the nature, scope, and timing of future exploration activities; the interpretation of geological observations; the possible size or scale of mineralized systems; the receipt of regulatory approvals, and the anticipated benefits of current and future exploration programs.

This release also refers to historical information, including results from past exploration activities and placer production figures. Such historical information has not been independently verified by Tectonic, may not be reliable, and should not be relied upon as current, NI 43-101 compliant data.

In addition, this release contains, detailed geological notes, and descriptive observations such as alteration styles, mineralogy and visible gold. These observations are preliminary in nature, may not be representative of the entire interval or system, and should not be relied upon as a guarantee of mineralized assay results or as the basis for any investment decision. Investors and readers are cautioned that visual estimates, core photographs, and geological descriptions are not substitutes for laboratory assay results and do not demonstrate the economic viability of any mineral deposit.

Forward-looking statements are not guarantees of future performance. They are based on a number of assumptions made as of the date such statements are provided, including, among others: assumptions regarding future gold and other metal prices; currency exchange and interest rates; favourable operating and political conditions; timely receipt of permits and regulatory approvals; availability of labour, equipment, and services; stability of financial and capital markets; availability of financing on acceptable terms; accuracy of exploration data and geological models; and the ability to successfully advance planned exploration programs. Many of these assumptions are beyond the control of Tectonic and may prove to be incorrect.

Forward-looking statements are subject to known and unknown risks, uncertainties, and other factors that may cause actual results, performance, or achievements to differ materially from those expressed or implied. These risks include, without limitation: risks inherent to mineral exploration and development; volatility of commodity prices; changes in laws, regulations, and policies; delays or inability to obtain required approvals and permits; availability of financing; general economic, political, and market conditions; labour disputes and shortages; equipment and supply risks; environmental and social risks; competition; inaccuracies in exploration results or geological interpretations; and other risks detailed from time to time in the Company’s continuous disclosure filings.

Although management believes the expectations expressed in such forward-looking statements are reasonable as of the date made, there can be no assurance they will prove to be correct. Readers are cautioned not to place undue reliance on forward-looking statements, historical information, or preliminary visual geological observations. Actual results and future events may differ materially from those anticipated. All forward-looking statements contained in this news release are expressly qualified by this cautionary statement. Tectonic disclaims any intention or obligation to update or revise forward-looking statements, whether as a result of new information, future events, or otherwise, except as required by applicable securities laws.
