Tectonic Metals completes phase 1 drilling at Flat

Executive Summary

• Tectonic Metals completed its 2025 Phase 1 drill program at the Flat gold project (7,718 m in 48 holes) and a 2,125‑line‑km high‑resolution drone magnetic survey.
• The company will host its first “Virtual Drill Core Shack” webcast on Sept. 4 2025 to present core observations and geological insights from Phase 1.
• CEO Tony Reda highlighted that the $12.7 M financing was 85 % oversubscribed, enabling a three‑rig drill campaign that met all Phase 1 objectives and sets the stage for Phase 2 and a maiden inferred resource.

Key Details

• Drilling Overview: 7,718 m drilled across 48 holes (core & RC) targeting Alpha Bowl, Chicken Mountain, Golden Apex, Black Creek, Jam and other intrusion‑related gold systems.
• Alpha Bowl: ~4,600 m in 24 holes; drill fences spaced ~100 m over a 600 × 700 m area; max depth 392 m; visible gold in quartz veins, multiple vein generations, strong sericite alteration.
• Chicken Mountain: 1,013 m core (5 holes) + 798 m RC (5 holes); additional 660 m core for heap‑leach column tests (two‑inch crushed material); observed sheeted quartz/ carbonate‑sulphide veining and pervasive sericite alteration.
• Golden Apex: 470 m total (269 m core, 201 m RC); intersected fine volcanic rocks with extensive carbonate & sulphide stringers; portable XRF showed Cu+Bi and As+W associations.
• Black Creek: 616 m in nine RC holes across a 300 m fence; intersected oxidized hornfelsed sediments transitioning to mafic intrusions; historic hole nearby graded 0.72 g/t Au over 73.76 m.
• Jam: 203 m in two RC holes (max depth 95 m); intersected veined augite basalt with arsenopyrite, pyrite and chalcopyrite; target felsic intrusion not intersected but surface alteration suggests deeper source.
• Geophysics: Completed a 2,125‑line‑km high‑resolution drone magnetic survey covering all six priority targets; data processing complete, 3‑D inversion modeling pending.
• Virtual Drill Core Shack: Webcast on Thu Sept 4 2025 at 7 a.m. PT / 8 a.m. MT / 10 a.m. ET; will feature core photographs, geological discussion and interactive Q&A; presentation materials available online in advance.
• Financing: Initial $7 M Phase 1 financing expanded to an $12.7 M raise (85 % oversubscribed), providing capital for the three‑rig drill campaign and upcoming Phase 2 work.
• Looking Ahead – Phase 2: Planned to advance Chicken Mountain toward a maiden inferred resource, continue follow‑up at Alpha Bowl, and explore additional intrusion targets; formal Phase 2 release forthcoming.

Notable Quotes

“What began as a $7‑million financing for phase 1 drilling in May, 2025, quickly expanded into an 85‑percent oversubscribed $12.7‑million raise… Every single phase 1 objective has been successfully achieved… This disciplined execution not only validates our approach but also sets the stage for phase 2 and introduces a new company objective – the delivery of Tectonic’s first‑ever maiden inferred resource.” – Tony Reda, Co‑founder, President & CEO
