Trailbreaker Resources Commences Drilling At The Swan Zone, Atsutla Gold Project, British Columbia

About this update from Trailbreaker Resources Ltd

July 27, 2026 - TheNewswire – Trailbreaker Resources Ltd. (TBK.V) ("Trailbreaker" or "the Company") is pleased to announce the completion of its maiden drill program at the Highlands Zone, and the drill’s mobilization to the Swan Zone at the Company's 100%-owned, 300 km² Atsutla Gold Project in northwestern British Columbia (BC), Canada. While drilling at the Highlands Zone targeted high-grade, vein-hosted gold (Au), silver (Ag), and copper (Cu) showings, drilling at the Swan Zone will be directed at a Cu-Au-Ag porphyry target. The two zones are 26 km apart and hosted in entirely different geological units. The Highlands Zone is hosted in the Jurassic Christmas Creek batholith, and the Swan Zone is hosted in the Cretaceous Glundebery batholith.

Daithi Mac Gearailt, CEO of Trailbreaker, commented, "The Swan Zone continues to be one of the most compelling targets in Trailbreaker’s portfolio. Over the past five years we have developed this prospect from a new discovery and have added layers of data through systematic exploration. Detailed geological mapping, combined with soil geochemical, induced polarization (IP) and airborne magnetic surveying have led us to this current stage. The now-completed Highlands Zone drill program was executed on schedule and within budget, and I anticipate drilling the Swan Zone to proceed in a similar fashion.” The completed diamond drill program at the Highlands Zone consisted of four holes totalling 883.40 metres. The drilling tested a strike length of 500 m and a vertical extent of 412 m. For details on the Highlands Zone drill target, see June 29, 2026 news release. Swan Zone Drill Target The Swan Zone is a Cu-Au-Ag porphyry target located in the Cretaceous Glundebery batholith. Trailbreaker has completed geochemical and geophysical surveys of significant extent to define the drill targets, which occur within a 1.5 km x 1.5 km multi-element (Au-Cu-Ag-arsenic [As]-molybdenum [Mo]-antimony [Sb]-bismuth [Bi]) soil geochemical anomaly. Rock grab samples from the zone grade up to 11.7 g/t Au, 212 g/t Ag, and 0.81% Cu. The geochemical anomaly is coincident with a 2.1 km x 1.4 km donut-shaped chargeability high feature (defined by a 2024 induced polarization surv...
