Final Results From The 2025 Drill Program At Chicken Mountain

ANCOUVER – Tectonic Metals Inc. reported on the drill program at Chicken Mountain. The results delivered thick, at or near-surface intercepts that reinforce Chicken Mountain as a bulk-tonnage, heap leachable Reduced Intrusion Related Gold System (RIRGS) within the 99,800-acre Flat Gold Project in Southwest Alaska. The 2025 drilling program has successfully advanced Chicken Mountain from an exploration target into a kilometre-scale resource growth opportunity, expanding the continuously mineralized footprint and delineating higher-grade corridors that may support potential starter-pit development scenarios.
Tectonic plans to resume drilling in early May 2026, and additional metallurgical test work is now underway, including 2-inch crush heap-leach column tests to investigate the viability of run-of-mine (“ROM”) gold processing. A more detailed news release outlining the Company’s 2026 plans and objectives is expected to be announced in the coming months.
“Chicken Mountain demonstrates a combination of scale, continuity and favorable metallurgy in a bulk-tonnage gold system. Unlike narrow vein deposits that rely on selective mining, this style of mineralization has the potential to support simpler, straightforward open-pit development, with broad, continuous zones that begin at surface and remain open in all directions.
What differentiates Chicken Mountain is the convergence of three key value drivers. First, scale: we’ve defined approximately 3.3 kilometres of mineralized strike to date, with widths approaching 700 metres, while drill testing only a fraction of the mapped intrusive complex. Second, predictability: a 100% drill success rate across 191 holes demonstrates a fertile and strong mineralizing system that can be targeted effectively. Third, metallurgy: previously reported heap-leach recoveries of up to 96%, together with ongoing work evaluating run-of-mine potential, point to a processing profile with meaningful capital and operating advantages.”
“Within this large mineralized, envelope, we’ve identified multiple higher-grade corridors that could represent potential mining starter-pit opportunities. Beyond the intrusion itself, the hornfelsed sedimentary rocks surrounding Chicken Mountain represent an additional, untested and underexplored opportunity. At Black Creek, located 6 km away, drilling intersected 4.50 g/t Au over 48.77 m with 7.79 g/t Au over 24.38 m hosted in hornfels – the same prospective host rock that surrounds Chicken Mountain.”
=As we move forward, our focus is clear: continued step-out drilling to define the ultimate scale of the Chicken mountain RIRGS system, advancing metallurgical work toward a potential run-of-mine flowsheet, and progressing toward a maiden mineral resource estimate. Each of these workstreams is aimed at systematically de-risking Chicken Mountain while preserving its significant growth potential.”
