Tectonic Metals Drills 4.05 G/T AU Over 30.48 Meters, Including 8.84 G/T AU Over 13.72 Metres at Flat Gold Project, Alaska
Tectonic Validates High-Grade Adit Zone Potential as 18,000-Meter Campaign Sets Stage for 2026 Resource Milestone

The news release dated December 22, 2025, reports high-grade and bulk-tonnage gold intercepts from the "Adit Zone" and "Chicken Mountain" targets at the Flat Gold Project, Alaska. Key highlights include hole CMR25-121, which returned 4.05 g/t Au over 30.48 meters, including a higher-grade core of 8.84 g/t Au over 13.72 meters. This drilling is part of a massive 18,373-meter Phase 2 program. The company reports a 100% "drill-hit" success rate at Flat, with 63 of 107 holes at Chicken Mountain ending in mineralization. Crucially, the company notes that assays for 103 additional drill holes are pending and expected in Q1 2026.
The impact is Material - Positive for several reasons: - Grade Confirmation: The intercept of 4.05 g/t Au over 30m is significantly higher than the typical 0.4–0.6 g/t Au grades seen in bulk-tonnage systems, suggesting the presence of "starter pit" high-grade zones that could drastically improve project economics. - Scale Verification: Mineralization has now been confirmed over a 3km strike length. The "Adit Zone" target alone shows a 550m width, supporting the thesis of a large-scale Reduced Intrusion-Related Gold System (RIRGS). - Continuity: The 100% success rate is statistically rare and reduces the geological risk of "missing" the system, though it does not guarantee economic viability. - Operational Momentum: Transitioning from a $3.7M asset base in late 2024 to a $22.8M asset base (Sept 2025) fueled by institutional capital (VanEck, Franklin Templeton) shows significant market "buy-in."
Tectonic Metals is focused on the Flat Gold Project in southwestern Alaska, located 40km from the 39Moz Donlin Gold Project. Flat is a district-scale (100k acre) RIRGS target. The flagship Chicken Mountain intrusion has a 100% drill success rate over 86 holes (now 107+). The project is notable for its metallurgy, showing 96% recoveries in heap-leach tests, which is exceptional for gold mineralization and suggests low-CAPEX potential.
