TECTONIC METALS PROVIDES END OF SEASON UPDATE AND SITE VISIT TOUR VIDEO FOR THE FLAT GOLD PROJECT

Tectonic Metals Inc. has provided an end-of-season update and launched an exclusive site visit tour video of the Flat gold project with Tectonic chief executive officer Tony Reda and Doyon Ltd. CEO Aaron Schutt.

"We have achieved a major milestone in our exploration efforts with the successful completion of our first-ever drill program. This program has provided invaluable insights into the potential of the Flat gold system, particularly within the historically drilled area of Chicken Mountain," said Mr. Reda, president and CEO of Tectonic. "We believe in the importance of continuous learning and growth, and our company has made significant progress in terms of our understanding of the logistics, operations and geology at Flat. The upcoming 2023 drill assay results will enhance our knowledge even more. With our camp and drills already in place, we are well positioned to leverage the knowledge and lessons learned from the 2023 program and achieve even greater success in the 2024 drilling season."

Highlights of 2023 Flat gold project drill program:

• Upgraded infrastructure -- the 4,100-foot-long airstrip has seen little to no activity in almost 20 years and therefore required maintenance and upgrading to support this year's activities.
• Multiyear camp established -- the multiyear, 24-person camp was built following four successful deliveries of camp materials to the Flat airstrip by a Hercules C-130 transport aircraft. Camp facilities remain on site and were successfully decommissioned for the winter season.
• Drill mobilization -- despite challenging, unforeseen weather conditions impacting visibility and access to the project, the Tectonic team safely and successfully overcame various obstacles, such as low-lying clouds, thick dense fog and above-average rainfall (over 50 per cent), to successfully mobilize workers, equipment, fuel, and the diamond and reverse circulating (RC) drills to site.
• Drilling -- 19 drill holes of combined diamond and RC drilling for a total of 2,633 metres were completed at Chicken Mountain with the objective of expanding mineralization along strike and at depth and drilling new discoveries.
• • Diamond drilling -- 915 metres of oriented diamond drilling across three holes to a maximum depth of 428.5 metres were completed to expand previously drilled mineralization along strike and to depth while providing valuable structural data to assist in understanding optimal orientation, the factors controlling mineralization and to target future drilling;
  • RC drilling -- 1,718 metres of drilling across 16 holes were completed by the RC drill to test new, historically undrilled areas of Chicken Mountain's gold-in-soil anomaly.
• Drills remain on site -- both the diamond and RC drills have been winterized and retained on site in anticipation of the 2024 drill season.
• Field mapping and prospecting -- field mapping/prospecting was performed during the drill campaign, which focused on the relationships between monzonite intrusions, volcanic cap rocks and hornfelsed Kuskokwim sediments, from Chicken Mountain northward toward the Golden Apex area. Approximately 49 representative rock samples were collected for continuing geochemical and petrographic work.
• Aerial high-resolution lidar/orthophoto survey -- completed over approximately 237 square kilometres covering the Flat volcano-intrusive complex, associated hornfelsed Kuskokwim sediments and historic placer mining activity/infrastructure within the project area. This advanced and precise lidar survey, combined with orthophotos, creates a comprehensive and detailed base map. With high resolution and accuracy, these data serve as a foundation for overlaying other geological and environmental data sets. Not only does lidar help identify surface structures and lineaments, it also provides valuable insights into the underground geology. This aids in geological mapping and can lead to the discovery of potential gold deposits associated with geological structures.
• Site visit -- management hosted a site tour for members of Doyon, investors, mining securities analysts and the board of directions.
• Health and safety -- more than 17,000 work hours were incurred on the project with no lost time incidents.

Diamond drilling

In total, three oriented diamond drill holes totalling 915 metres were drilled over a 500-metre strike length within the core of Chicken Mountain, targeting to depth the main interpreted north-northwest-oriented structural zone and coincident gold-in-soil anomaly, which transects the mountain. All holes were drilled at an azimuth of 90 degrees and dips of minus 50 degrees. All holes intersected variably sericite altered biotite-quartz and leucocratic quartz monzonitic host rock throughout their lengths, with complete to partial oxidation of sulphide minerals and strong iron staining within specific structural zones persisting to depth. Veining comprising distinct quartz, quartz-sulphide, quartz-oxide, carbonate or clay infill ranging from one to two millimetres up to several centimetres were encountered at variable per-metre densities throughout all three holes. Within zones of lower oxidation, arsenopyrite followed by pyrite was identified as the major sulphide species, occurring primarily as fine-grained vein fill, and as somewhat coarser-grained disseminations within strongly sericite altered wallrock adjacent to quartz dominant veins. Orientations of quartz dominant veins interpreted to be the main mineralizing event average 47.1/295.8 (dip/dip direction) indicate drill holes are well oriented with respect to overall mineralized zone-veining trends.

Reverse circulation drilling

In total, 16 RC drill holes totalling 1,718 metres were drilled to test the eastern and western margins of the Chicken Mountain structural zone as delineated by historic gold-in-soil anomaly. The RC hole planned target depth was 200 metres; however, the achieved depth varied from 53.3 to 201.2 metres and averaged 107 metres with early hole termination due to excessive water influx on holes drilled in the valley. RC chip logging indicates all holes intersected variably sericite-clay altered, variably oxidized biotite-quartz monzonite as expected.

Drill assays

All drill core and RC chip samples have been submitted to ALS Global Facility in Fairbanks, Alaska, for shipping to ALS Global Reno, Nev., where preparation and fire assay (30-gram with atomic absorption finish (Au-AA23)) will be performed. Multielement geochemistry for 48 elements by four-acid digestion with inductively coupled plasma mass spectrometry finish (ME-MS61) and mercury analysis by aqua regia and ICP-MS finish (Hg-MS42) will be performed at ALS Global Vancouver.

Complete analytical results are expected to be received and announced in a timely and contextual manner anticipated to be in Q1 2024.

The Flat gold system -- Alaska's next Tier 1 opportunity

Tectonic is currently assessing the Flat gold system in partnership with Doyon, one of Alaska's largest native regional corporations and a strategic Tectonic investor. The Flat gold system is a network of interconnected geophysical anomalies that indicate six confirmed and potential underexplored bulk-tonnage intrusion-related gold systems. The system spans a 20 km trend and has produced approximately 1.4 million ounces of placer gold between 1908 and 1966.

Tectonic is currently evaluating Chicken Mountain, a confirmed intrusion that features a four-kilometre-long gold-in-soil anomaly and 55 historic drill holes, all of which intersected and 25 of which ended in gold mineralization. Highlight intersects from this historical drilling include 12.56 grams per tonne Au over 24.7 m, 211 g/t Au over 1.4 m, 0.98 g/t Au over 76 m, 1.36 g/t over 36.6 m and 5.62 over 7.6 m.

Preliminary metallurgical analysis to date has demonstrated rapid leach kinetics and gold recoveries averaging 95 per cent from bottle roll testing. This, combined with gold intersections at or near surface, suggest Chicken Mountain could represent an open-pit, heap leach opportunity.
