Tectonic Announces Completion of 2022 Inaugural Field Program at Flat Gold Project, Alaska

VANCOUVER, December 5, 2022 - Tectonic Metals Inc. (TECT:TSX-V)(TETOF:OTCQB(T15B:FSE) (the "Company" or "Tectonic") today announced the completion of the Company's inaugural field program at the Flat Gold Project ("Flat"), an intrusion-hosted, bulk tonnage gold project located in the Kuskokwim Mineral Belt of southwestern Alaska, some 40 kilometres ("km") north of the Donlin Gold Project.

Tectonic's surface field program at Flat represents the first exploration work at the property in more than 20 years and comprised ground-truthing, channel/grab sampling of historic bedrock exposures and mechanical excavation and sampling of new trenches at Flat's main zone, Chicken Mountain ("CM"), comprising of a 3800 metre ("m") long and up to 600m wide gold-in-soil anomaly.

A link to detailed maps of Tectonic's 2022 trenching program may be found here.

Tony Reda, Tectonic President & CEO, commented: "Our year one objective at Flat was to build a strong technical foundation that will provide the basis for a comprehensive exploration program, including drilling, at Flat in 2023. Our work this year included a metallurgical test program on historical drill core, supplemented by extensive geological, geochemical, and geostatistical modelling, relogging of the historical drill core, petrography, trenching, channel sampling, ground truthing, lineament analysis, historical geophysical interpretation, and a logistical and onsite infrastructure audit. Success next year does not only mean discovering gold but also evaluating those ounces found as accurately as possible with respect to metallurgy and mining methods. We want to put our best foot forward going into next year's drilling program and anticipate that our technical focus in 2022 will bolster the value of any ounces found while continuing to guide our exploration strategies at Flat.

Flat Gold Project - Exploration Objective

The primary objective of the program was to gain a greater understanding of the geological opportunity at Flat by focusing on gathering additional geological information and assessing the extensive undrilled gold-in-soil anomalies at CM where historic soils outline an open-ended gold-in-soil anomaly extending 3,800m x 600m in a north-northwest orientation over the core of exposed quartz monzonite intrusion. The western portions of the soil anomaly have been untested by historical drilling and trenching with highlights including up to 8.8 grams per tonne gold ("g/t Au") in soil and up to 3.4 g/t Au in surface grab samples. In total, 273m in 3 new trenches were excavated and mapped on the CM target with 180 continuous channel samples and 18 focussed grab samples collected. A further 7 bedrock exposures in accessible historic trenches and placer mining cuts in the CM area were sampled and mapped with 71m of channel samples and 7 grabs collected.

In anticipation of a comprehensive 2023 exploration program, the Company conducted additional reconnaissance to further assess the surficial conditions on the property and investigate accessibility/navigability based on existing infrastructure.

About the Flat Gold Project

The Flat Gold Project is an intrusion-hosted, bulk tonnage gold project located in southwestern Alaska, just 40km north of the giant Donlin Gold Project, which is owned equally by Barrick and NOVAGOLD and have set a 2022 budget at Donlin of USD $60 million (see Barrick news release dated July 28, 2022).

Flat consists of 92,160 acres of mostly Native-owned land belonging to Doyon, Limited, a leading Alaska's Native Regional Corporation and the largest private landholder in the State of Alaska. Doyon and Tectonic have formed a mutually beneficial mineral lease property agreement covering all aspects of exploration through to production, including royalties and ESG provisions. The resulting agreement aligns the interests and expectations of both parties involved, reduces risk, and creates a process that can advance a project from discovery through development and production to final reclamation.

Flat represents a rare opportunity in a tier-one jurisdiction:

• A large-scale, intrusion-hosted gold system
• Documented as the 4th largest placer gold district in Alaska with over 1.4Moz of gold produced via placer mining*
• 55 historical drill holes at the Chicken Mountain target, all of which have intersected mineralization
• Historic drilling indicates mineralization begins at surface and remains open in all directions with an average vertical drill depth of ~100m
• 3,800m long, up to 600m wide, gold-in-soil anomaly (open for expansion)
• Historical mineralized trenches, some of which remain untested by drilling
• Opportunity for new discoveries within blind-to-surface portions of the intrusive complex
• In close proximity to a world-class gold deposit (Donlin)
• Situated on Native Owned Land with a full-scale mineral lease property agreement covering all aspects of exploration through to production, including royalties and ESG provisions
