Trailbreaker Resources drills Swan Zone at Atsutla Gold Project

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 survey), as well as a zone of elevated potassium marked by a magnetic low signature indicated from 2024 airborne magnetic and radiometric surveys.

Although limited historic drilling has been conducted in the valley adjacent to the Swan Zone, the Swan Zone itself has never been drilled. The diamond drill program will target surface geochemical anomalies and geophysical anomalies. The program will test an estimated strike length of 1,000 m to a vertical depth exceeding 400 m.

The Company anticipates this preliminary drill program will improve our understanding of mineralization controls and the overall deposit model at the Swan Zone, to support the design of future, more targeted drill campaigns. Other Future Drilling in 2026 In September 2026, Trailbreaker plans to drill several Cu-Au porphyry targets at the Coho property, located 30 km northwest of the Mt. Milligan mine in central BC. For further details of these programs, see the May 25, 2026 news release .

More about the Atsutla Gold Project The Atsutla Gold Project is centered over the regional-scale Teslin-Thibert fault system which marks the contact between the Quesnel and Cache Creek terranes. Gold mineralization is associated with Mesozoic batholitic intrusions that are the predominant geological unit on the property. Since discovery in 2020, Trailbreaker has outlined five significant zones of gold mineralization on the property, across a span of 26 kilometers .

These are: Highlands Zone – A 2.0 km by 1.5 km area in the western Atsutla Gold Project region, with veins containing coarse visible gold assaying up to 630 g/t Au and 1,894 g/t Ag Christmas Creek Zone – Gold-bearing quartz veins 1.5 km east of the Highlands Zone, with rock samples assaying up to 102 g/t Au and 524 g/t Ag Snook Zone – High-grade veins 3.5 km northeast of the Highlands Zone, with rock samples assaying up to 53.3 g/t Willie Jack Zone – 1.25 km long gold-in-soil anomaly with soil samples assaying up to 3.77 g/t Au and rock samples up to 9.9 g/t Au Swan Zone – A Cu-Au-Ag porphyry target defined by a 1.5 km x 1.5 km multi-element soil geochemical anomaly ( Au-Cu-Ag-As-Mo-Sb-Bi), with rock grab samples grading 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 (defined by a 2024 induced polarization survey) as well as a zone of elevated potassium marked by a magnetic low signature indicated from a 2024 airborne magnetic and radiometric survey.
