VANCOUVER, BC / ACCESS Newswire / September 10, 2025 / Tectonic Metals Inc. ("Tectonic" or the "Company") (TSX-V:TECT)(OTCQB:TETOF) today announced the first assay results from the Company's 2025 Phase One Drill Program at the Alpha Bowl intrusion target within the Company's flagship Flat Gold Project ("Flat"), located in southwestern Alaska.
Flat represents a significant reduced intrusion-related gold system ("RIRGS") district in North America, hosting multiple kilometre-scale gold targets across a 99,000-acre land position. Alpha Bowl, measuring ~1.5 km by 1.0 km, is a completely blind-to-surface target tested systematically for the first time in 2025. It also hosts one of Alaska's most prolific placer gold creeks, with over 650,000 ounces of recorded historic production 1 , and represents the northern extension of Chicken Mountain - Flat's largest intrusion target (6.5 km by 6.0 km) where currently over 3 kilometres of drilled mineralized strike length demonstrates the potential for an open-pit, free milling, heap leachable gold mining opportunity.
First RC Drill Hole Confirms High-Grade Gold - Highlights
Tectonic's first reverse circulation ("RC") drill hole of the 2025 season, CMR25-035, was drilled to a 124 m length and intersected two mineralized gold zones, highlighted by:
- 2.23 grams per tonne gold ("g/t Au") over 41.15 metres ("m") including 4.00 g/t Au over 21.34 m with 13.25 g/t Au over 4.57 m
- Another significant gold zone was intersected at the top of this drill hole returning 0.58 g/t Au over 45.72 m
- Systematic fence drilling across a 600 m x 700 m area with approximately 100 m spacing was designed to evaluate scale, grade, continuity, and structural orientation of mineralization
- CMR25-035 was drilled on the eastern edge of the northernmost drill fence and intended to provide data on the eastern extent of the Alpha Bowl gold system. CMR25-035 intersected significant gold zones, confirming that the system remains open in multiple directions and is significantly larger than previously interpreted.
- Importantly, this hole represents a 250-metre step-out along strike and 200 metres east of Tectonic's 2024 Alpha Bowl discovery drill hole (CMR24-026), which returned 1.2 g/t Au over 65.5 metres, including 6.0 g/t Au over 6.1m with 21.7 g/t Au over 1.5m; see Tectonic News Release dated March 03, 2025. Together these results validate the presence of high-grade gold (>10 g/t Au) at Alpha Bowl and 2025 Phase One & Two drilling has the potential to delineate these higher grade gold zones at scale.
Follow-up drilling at this location is planned as part of the 2025 Phase Two program, now underway. A dedicated news release outlining Phase Two plans will be issued in the coming weeks.

Tony Reda, Co-Founder, President & CEO of Tectonic Metals, commented:
"Sometimes the biggest opportunities reveal themselves where you least expect them. Alpha Bowl is a blind target and yet in only a few drillholes we've been able to intersect high-grade gold mineralization. Hole CMR25-035 was drilled to test the edge of the Alpha Bowl system, but instead it delivered over 40 metres of 2.23 g/t gold, including 21 metres of 4.00 g/t and a peak of 13.25 g/t over 4.57 metres. These initial results tells us three things: first, we have not defined the eastern edge of this system; secondly, we are only beginning to tap into its true potential; third, high-grade gold is present and possibly at scale. With assays pending from 47 additional holes from Phase One, and Phase Two drilling underway, we are entering an even more exciting period of discovery and growth. Shareholders can look forward to a steady cadence of results as we advance what we believe will be a pivotal year for the Flat Gold Project."

About Alpha Bowl
The Alpha Bowl target, interpreted as a potential large, reduced intrusion-related sheeted quartz vein gold system ("RIRGS"), was the principal focus of Tectonic's 2025 Phase One drill program. Drilling followed up on the Company's 2024 discovery, which first identified bedrock gold-bearing zones beneath surficial cover and within areas historically disturbed by placer mining (see Tectonic news release, March 3, 2025).
Phase One drilling at Alpha Bowl totalled approximately 4,600 m across 24 drill holes, utilizing both diamond core and reverse circulation (RC) drill methods. The program tested an area measuring roughly 600 m by 700 m, with drill fences arranged in parallel lines spaced ~100 m apart. Drilling specifically targeted sheeted quartz vein systems developed within granitoid intrusions - a hallmark setting of reduced intrusion-related gold systems. Diamond drill holes were completed to maximum depths of up to 392 m.
Alpha Bowl Rock Types
The rocks at Alpha Bowl are mainly coarse-grained intrusions called monzonite to syeno-monzonite, which sometimes contain xenoliths of dark fragments of other rock types. Narrower dikes of varying composition cut through the main body. Tectonic observed multiple generations of mineralized quartz and carbonate veins in all logged rock types, indicating the system was long-lived and repeatedly active.
Vein Types and Potential Mineralization Indicators
Drilling has revealed three main types of potentially gold-related veins:
- Sheeted quartz-sulfide veins - closely spaced, consistently oriented veins of quartz with sulfide minerals (chalcopyrite, pyrrhotite, arsenopyrite). These carry a mix of elements like copper, bismuth, silver, molybdenum and occasionally visible coarse gold.
- Quartz-carbonate-arsenopyrite veins - larger veins with alteration halos (sericite, carbonate, arsenopyrite) that can appear brecciated (broken and resealed). These veins are chemically distinct, marked by arsenic, antimony, mercury, tungsten and molybdenum. They often align with the finer-grained dikes, suggesting repeated pulses of mineralizing fluids.
- Arsenopyrite stringers - zones dominated by arsenopyrite occurring as dense networks of fine- to coarse-grained veins.
Later generations of calcite-rich veins cut across all three of these earlier vein types, sometimes showing oxidation and secondary copper minerals (like chalcocite and copper oxides).
Geological Significance
The presence of multiple cross-cutting vein types in drill core indicates that the Alpha Bowl system included multiple fluid phases and was active over an extended period, with early high-temperature mineral assemblages subsequently overprinted by later, lower-temperature mineralization. This telescoping of mineralizing events is a recognized feature of intrusion-related gold systems and highlights that Alpha Bowl possesses key attributes of a large, long-lived mineralizing environment. In addition, the observation of repeated "crack-and-seal" textures within quartz-carbonate veins confirms that mineralizing fluids circulated through the system in multiple pulses as it evolved and cooled.

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., Vice President of Exploration, who is a Qualified Person in accordance with Canadian regulatory requirements set out in National Instrument 43-101.
The analytical work for the 2025 Flat drilling program was performed by MSA Labs (MSA) an internationally recognized and accredited analytical services provider, which is independent of Tectonic. All core and RC samples were submitted to MSA's Fairbanks, Alaska facility. Certain sample shipments were shipped to MSA's Prince George, British Columbia facility to expedite analysis times. At either lab the entire sample was dried, crushed to 2mm and riffle split into nominal 500 g subsample jars for analysis (prep code CRU-CPA). Sample split jars were then analysed for gold using PhotonAssayTM (CPA-Au1). If additional nominal 500-gram PhotonAssay TM analysis splits are conducted for a given samples results from all splits are combined on a weight average basis. All initial PhotonAssay TM samples will undergo further analysis for a suite of 48 elements (IMS-230), with pulverization of jar contents to 85% passing 75um (PPU-510), with four acid digestion and ICP-MS finish.
QA/QC procedures for the drill program included insertion of a certificated reference material every 20 samples, blanks at rate of approximately every 25 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 Fairbanks, Alaska, utilizing strict Chain of Custody protocols.
