Trailbreaker Resources Mobilizes for Coho Copper-Gold Exploration

Trailbreaker Resources Ltd. (TBK.V) has mobilized a field team to its Coho property in central British Columbia to kick off a surface exploration program ahead of a planned September 2026 drill campaign. The program focuses on two key areas: reconnaissance along the underexplored western boundary known as the Masu zone, and ground-truthing of drill hole locations at the Coho zone, a copper-gold (Cu-Au) porphyry target. CEO Daithi Mac Gearailt emphasized the compelling opportunity at Coho and the team's systematic approach to sampling territory with little historic exploration. This work follows up on results from Pacific Empire Minerals at the adjacent Trident property, where drilling returned 240.0 meters of 0.64% Cu, 0.41 g/t Au, and 2.8 g/t Ag. The Masu zone lies 3.3 km east of those high-grade intercepts, making it a priority for prospecting, geological mapping, and grid soil geochemical surveys.

The 8,000-hectare Coho property was acquired through an option agreement in May 2025, and the primary target is the Coho zone—a drill-ready Cu-Au porphyry target that has never been drilled. Recent geochemical and geophysical surveys identified a coincident chargeability and resistivity anomaly associated with high-grade gold and copper surface samples. The property sits in the prolific Quesnel terrane, 30 km west of Centerra Gold’s Mount Milligan mine (1.7 B lbs Cu and 4.3 Moz Au reserves) and near Pacific Ridge Resources’ Chuchi project, where 2024 drilling intersected 382.0 m of 0.19% Cu, 0.12 g/t Au. Historic surface grabs at Coho returned up to 16.15 g/t Au, 16.35% Cu, and 67.3 g/t Ag. Airborne ZTEM and ground IP surveys outlined a 400 m x 250 m porphyry intrusive complex with a two-limbed IP anomaly spanning over 1.4 km. The Coho zone is interpreted to be on the same fault structure as the BP zone at Chuchi, supporting the potential for a cluster of alkalic porphyry deposits.

This exploration program is a critical step toward the September 2026 drill campaign at the Coho zone, which aims to test a compelling geophysical and geochemical target. The company believes the Coho property may host a significant Cu-Au porphyry system similar to neighboring deposits. With the field team now on the ground, Trailbreaker is poised to advance this project rapidly, providing potential value for shareholders and adding to the growing copper-gold potential in central BC.
