American Marconi Wireless News - Tectonic Metals Announces Phase Two Drilling at Flat Gold Project, Alaska

Phase Two Drilling Underway with a Planned Target of 9000 Metres of Core and RC Drilling

VANCOUVER, BC / ACCESS Newswire / September 25, 2025 / Tectonic Metals Inc. ("Tectonic" or the "Company") (TSXV:TECT)(OTCQB:TETOF) today announced an update on the 2025 Phase Two drill program at the Company's flagship Flat Gold Project ("Flat") in southwestern Alaska. Flat covers 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.

Flat is emerging as a potential tier-one, free-milling, heap-leachable gold mining opportunity strategically located near one of the world's largest undeveloped gold deposits, the Donlin Gold Project.

Highlights of the 2025 Phase Two Drill Program

• Environmental Stewardship: Development of an integrated Environmental Baseline Study program in support of long-term planning

Peter Kleespies, Vice President of Exploration, commented:

"Phase One at Flat delivered on every objective, with over 7,700 metres drilled across multiple intrusion targets, and our very first hole of the 2025 returned two strong zones of mineralization, including high-grade gold such as 4.0 g/t Au over 21.34m with 13.55 g/t Au over 4.27m.

Phase Two builds on that momentum with systematic delineation drilling at Chicken Mountain - the largest and most advanced system on the property - while also stepping out at Alpha Bowl, where we have made one of Alaska's newest high-grade gold discoveries. Just as importantly, our investments in logistics and infrastructure will allow us to restart drilling as early as spring 2026 and transition Flat closer to year-round operations. Together, these programs are laying the foundation for Flat's first mineral resource estimate and a future Preliminary Economic Assessment."

Primary Target: Chicken Mountain - Establishing the Foundation for a Maiden Resource

Scale & System: Chicken Mountain is a 6.5 km x 6.0 km monzonite intrusion with over 3 km of drilled mineralized strike from 86 drill holes, more than half of which ended in gold mineralization, including two deep holes exceeding 400m in length. Despite this, drilling to date has tested only a fraction of the Chicken Mountain intrusion, which is only one of six kilometre-scale intrusion targets across the 99,000 acre Flat land position.

Evidence of a Large Gold System: Every creek draining from Chicken Mountain, including Alpha Bowl's Flat Creek, has historically yielded placer gold, underscoring the size and fertility of the system.

Phase Two Design: Systematic section-based drilling with fences of diamond and RC holes across 1 km of strike. Drill orientations are optimized (azimuth 120°, dips -55° to -70°) to cut the northeast-striking, west-dipping sheeted vein arrays identified during Tectonic's 2023 and 2025 oriented core programs.

Objective: Deliver a supplementary dataset that will assist in supporting a Maiden Mineral Resource estimate and establish the technical foundation for a future Preliminary Economic Assessment (PEA).

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.
