Chicken Mountain Programs For Acceleration Towards Resource Readiness

VANCOUVER – Tectonic Metals Inc. reported on 10 of the 79 holes drilled during the 2025 drill campaign at Chicken Mountain – a bulk-tonnage, open-pit, heap-leachable gold opportunity and one of six kilometre-scale intrusive centres at the Company’s flagship ~99,800 acre Flat Gold Project in southwestern Alaska.
The Chicken Mountain intrusion (6.5 x 6.0 kilometres) is the largest and most geologically understood intrusive center at Flat and widely recognized as the primary lode source of the 1.4 million ounces of placer gold historically mined from the surrounding drainages. To date, the 2025 drill campaign represents the largest and most comprehensive program ever completed at Flat, totaling 18,373 metres (m) drilled across 125 holes, including 10,780 m in 79 holes at Chicken Mountain.
The ten drill holes account for just 1,811 m – approximately 17% of the total 2025 drilling at Chicken Mountain. Assay results from a further 114 drill holes across Chicken Mountain, Alpha Bowl, and other intrusive centres are pending and will be released as they are received, validated, and incorporated into the Company’s geological model.
The 2025 Phase One and Phase Two drilling programs were strategically designed to accelerate Chicken Mountain toward resource readiness by extending mineralization along strike and at depth, validating historical information, tightening geological and structural controls, generating two-inch coarse-crush metallurgical samples for heap-leach column testing and collecting a comprehensive dataset required for 3D resource modelling and future engineering studies.
Definition of vectors to higher grade mineralized zones will be assisted by data collected and interpreted from orientated drill core measurements, characterization of alteration assemblages, vein geometry, vein density and quantitative assessment of mineralization styles. Tectonic also utilized reverse-circulation (RC) drilling to rapidly test for shallow, near-surface mineralization and extend mineralization across strike.
Together, these objectives underpin the project’s progression from exploration drilling toward formal resource delineation and future economic assessment.
Tony Reda, Co-Founder, President & CEO, said, “These latest results both justify and motivate our ambitious exploration strategy at Chicken Mountain. Big targets merit big programs, and with over 10,000 metres of drilling at Chicken Mountain alone and assays pending from 69 holes, we are only at the very front edge of what this system can reveal.
As more assays come in, they will refine grade, continuity, geometry and starter-pit potential – and ultimately form the foundation of Flat’s maiden resource estimate and PEA. What excites me most is that everything we are seeing points to a real opportunity for a future open-pit, heap-leach gold mine in one of Alaska’s great gold districts.”
