Black Creek is one of six district-scale Reduced Intrusion-Related Gold System (“RIRGS”) targets at Tectonic’s flagship 99,840-acre Flat Gold Project (“Flat”) in southwest Alaska, U.S. Located six kilometres (“km”) north of Chicken Mountain, where a maiden Mineral Resource Estimate (“MRE”) is targeted for Q1 2027, Black Creek has delivered repeated high-grade gold intercepts within broad mineralized envelopes, demonstrating continuity of mineralization across a growing footprint and providing further evidence that Tectonic is vectoring towards a second gold system within the Flat district.
Beyond the Headline
Tectonic Metals reported results from six (6) RC drill holes totaling 525m at its Black Creek prospect, located approximately 6 km north of Chicken Mountain. Hole CMR26-152 returned an exceptionally strong gold intersection of 5.61 g/t Au over 41.15 m, including 12.94 g/t Au over 13.72 m, within 2.86 g/t Au over 91.44m from 22.86m. The overall intersection in this hole is 262 gram metres while the 41.15m higher grade section included is 231 gram metres. This result substantially strengthens the possibility that Flat contains two separate, significant intrusion-related gold systems (Figure 1-1).
Hole CMR26-159 was collared 100m south of 2025 high-grade discovery hole CMR25-059 (4.50 g/t Au over 48.77 m) and 30m south of holes CMR26-152 (5.09 g/t Au over 21.34 m) and CMR26-153 (1.89 g/t Au over 57.91 m), both of which also ended in mineralization. All of these holes contained intersections with greater than 100 gram metres with two of the holes including the new hole just released having greater than 200 gram metres as shown in Table 1-1 below.

| Hole | Interval (m) | Gold Grade (g/t) | Au grade × length (gm) |
| CMR26-159 | 91.44 | 2.86 | 262 |
| including | 41.15 | 5.61 | 231 |
| including | 13.72 | 12.94 | 178 |
| CMR25-059 | 48.77 | 4.50 | 219 |
| CMR26-152 | 21.34 | 5.09 | 109 |
| CMR26-153 | 57.91 | 1.89 | 109 |
The other five holes returned lower grade values with the best result in Hole CMR26-158 of 0.46 g/t Au over 30.48m from 0.00m including 1.23 g/t Au over 6.10m from 7.62m.
Geologically, Black Creek’s gold mineralization is predominantly hosted in hornfels, in contrast to the primarily monzonite-hosted mineralization at Chicken Mountain. Hornfels also occurs along the margins of other intrusion-related targets across Flat, including Golden Apex, Horseshoe, Jam and Caribou, as well as the margins of Chicken Mountain itself, making each a high-priority focus for future drilling.
Drilling at Black Creek has tested only a fraction of the overall target with only 18 holes totaling 1,600m completed to date. The initial drilling campaigns have outlined mineralization across an area of only approximately 100m by 200m and to a vertical depth of less than 200m. This relatively small drilled area, however, occurs within a much larger 1,500m by 700m gold-in-soil anomaly, of which over 85% remains untested. Furthermore, both sit within an even larger 1.5km by 2.5km geophysical anomaly interpreted to represent an intrusive centre.
Year-to-date through October 2026, Tectonic completed 31,000 m of drilling in 166 holes, focused mainly on resource delineation and expansion at Chicken Mountain. Upcoming Company catalysts include:
- Pending assays from approximately 25,000m in over 120 holes, mainly at Chicken Mountain, providing a steady flow of news through the remainder of 2026.
- Test results from 15 heap leach columns at Chicken Mountain.
- A Maiden MRE for Chicken Mountain targeted in Q1 2027, followed by a Preliminary Economic Assessment targeted in Q2 2027.
- 2026 regional soil sampling results to refine and prioritize targets across the Flat district, including Black Creek.
Comments
This an excellent result from drilling on the Black Creek target which has had only very limited drilling to date. Seventeen (17) of the 18 holes drilled thus far have intersected gold mineralization with four (4) of these holes intersecting spectacular high grade results greater than 100 gram metres substantially strengthening the possibility that Flat contains two separate, significant intrusion-related gold systems.
These 18 holes have only tested a small part of a very extensive target zone at Black Creek outlined by soil geochemistry (1,500m by 700m) and geophysics (1.5km by 2.5km). Importantly, Black Creek’s gold mineralization is predominantly hosted in hornfels, in contrast to the primarily monzonite-hosted mineralization at Chicken Mountain which opens up more potential target areas including on Chicken Mountain.
The Company will have a lot of news flow from drill results going forward in Q4 into the New Year. Major catalysts are the Maiden MRE for Chicken Mountain targeted in Q1 2027, followed by a Preliminary Economic Assessment targeted in Q2 2027.
