VANCOUVER, BC / ACCESSWIRE / September 5, 2024 / Tectonic Metals Inc. (TSX-V:TECT)(OTCQB:TETOF)(FSE:T15B) (the “Company” or “Tectonic”) today announced 2024 assay results from four historical core holes drilled in 2003 at the Flat Gold Project (“Flat”), Alaska. These 2024 drill assay results have revealed multiple new, intrusion-hosted gold corridors at Chicken Mountain and validated the presence of a Reduced Intrusion-Related Gold System (RIRGS) at Golden Apex, one of six identified intrusion targets at Flat.

Tony Reda, President & CEO of Tectonic Metals, stated: “The results from our historic drill core assaying program continue to underscore the potential for uncovering a significant gold resource at not one but several intrusions at Flat. This low-cost initiative has not only validated and expanded upon existing historical data but also offered critical insights into the geometry of the mineralized envelope, as well as the orientations of higher-grade corridors and structures within the known mineralized intrusion. Additionally, the program has provided valuable geochemical vectoring information that points to potential new, previously unexposed intrusion-hosted targets. By deepening our geological understanding of the Flat gold system and identifying emerging drill targets, we are strategically positioning Tectonic for success in making new discoveries in our forthcoming exploration programs.”

In 2003, the previous explorer at the Flat Gold Project completed a diamond drilling campaign during which the recovered drill core was selectively sampled and assayed, despite initial assay results of up to 27 g/t Au. In 2024, through an extensive and meticulous relogging campaign, Tectonic has now identified and analyzed previously unsampled sections of these 2023 drill cores. Four historical drill holes from Golden Apex and Chicken Mountain, totalling 1,043.5 meters with 720 metres recently assayed by Tectonic, are situated in largely unexplored areas of the Flat Gold Project. These results validate the presence of intrusion targets and reveal significant new discoveries that warrant immediate follow-up drilling. This data highlights the Project’s substantial exploration potential and capability to host multiple large-scale volcanic intrusions and associated gold mineralization.

Key Findings

1. Identification of new mineralized zones, confirmation of historical intersections, new sampling results in increased mineralized widths, and validation of geochemical and geophysical vectors to mineralization. Additionally, recent Tectonic 3D magnetic inversions reveal that the mineralization associated with gold bearing intrusive rocks at Chicken Mountain is linked to very low magnetic susceptibility
2. Recent structural data and the application of the Reduced Intrusion-Related Gold System (“RIRGS”) geological model to Flat clearly demonstrate that the four historical drill holes were not optimally oriented or specifically targeting RIRGS mineralization.
3. Golden Apex: A RIRGS target is now validated at this 2.5 kilometre x 2.0 kilometre (“km”) intrusion target.
4. Assaying of unsampled sections of historic drill holes confirms the historic intercepts and identifies a previously unrecognized gold mineralized zone.
5. Drill hole GA03-02 findings include the following:

GA03-02 Highlight Intervals:

• 12.34 m @ 1.08 g/t Au
• 22.86 m @ 1.00 g/t Au
• 9.60 m @ 0.93 g/t Au
  • Initially, a buried intrusion was believed to exist at depth at Golden Apex. However, recent drill assays from 2024 have validated the presence of RIRGS distal mineralization. These assays and resulting geochemical zonation patterns suggest that it is closer to the surface than previously thought, particularly in the western part of the target area. This conclusion is further supported by recent Tectonic 3-D inversion of magnetic data, which reveal that the mineralization associated with gold-bearing intrusive rocks at Chicken Mountain are linked to very low magnetic susceptibility. This low magnetic signature has now been identified and mapped at Golden Apex, just west of drill hole GA03-02, prompting Tectonic to drill this target this 2024 drill season.
  • There are only two historical drill holes at Golden Apex across the expansive 2.5 km-long and 2.0 km-wide Golden Apex target. Both drill holes were not drilled in the optimum orientation, were drilled directly into a fault zone, and did not adequately test for the presence of underlying intrusions in the area. These new assay results will be used to further support additional drilling at Golden Apex aligned to the RIRGS model.

vi. Chicken Mountain: Drill holes CM03-25 and CM03-26 findings include the following: 2024 assaying of unsampled sections from two historical drill holes at the northeastern portion of Chicken Mountain, a 6.5 km long x 6.0 km wide intrusion target:

• Increased Mineralization: Assaying of unsampled sections of two historical drill holes significantly enhanced both the width and grade of gold mineralization compared to the selectively sampled intervals from 2003 historical analyses.
• New Mineralized Corridors: Newly identified gold mineralized zones in these historical holes suggest previously unrecognized northeast-trending mineralized corridors. These zones remain open for expansion along strike and at depth.
• Drill Hole CM03-25 revealed 263.65 metres of gold mineralization, which started and ended within mineralized zones.

CM03-25 Highlight Intervals:

• 35.06 m at 1.05 g/t Au
• 7.62 m at 5.66 g/t Au
• The broader mineralized interval is 263.65 metres at 0.40 g/t Au and the nearest adjacent drill hole is 170 metres away.
• Drill Hole CM03-26 revealed 288.22 metres of gold mineralization starting and ending in mineralization. The closest adjacent drill hole is 233 m away.

CM03-26Highlight Intervals:

• 19.81 m at 0.53 g/t Au
• 7.62 m at 1.00 g/t Au

The Flat Gold System – Alaska’s Next Tier 1 Opportunity

Tectonic Metals is advancing the 99,840-acre Flat Gold System and recently published the results of the Company’s 2023 drill program at Flat’s Chicken Mountain intrusion target where all 19 holes intersected gold. ¹ Flat is a network of interconnected geophysical anomalies that indicate six confirmed and potential 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. ²

Tectonic’s 2023 drill program demonstrated gold at 300 m depth and delineated 1.8 km of mineralized strike with mineralization remaining open in all directions ¹ . These results further strengthen the case for a potential open-pit, multi-million-ounce opportunity. A total of 74 holes have been drilled at the Chicken Mountain intrusion target with each drill hole intersecting gold mineralization, which is remarkable and reinforces the notion that Flat is a very robust gold system ^1,3 .

Preliminary metallurgical analysis to-date has demonstrated rapid leach kinetics and gold recoveries averaging 95% from bottle roll testing. ⁴ This, combined with gold intersections at or near the surface, suggests Chicken Mountain may also be an open-pit, heap leach opportunity.
