Trailbreaker Resources Mobilizes Team to Coho Property for Surface Exploration Ahead of September Drill Program

Trailbreaker Resources Ltd. (TBK.V) announced that it has mobilized a field team to its Coho property in central British Columbia to initiate a surface exploration program in preparation for its September 2026 drill campaign. The program focuses on two main objectives: reconnaissance exploration along the underexplored western boundary, known as the Masu zone, and ground-truthing drill hole locations at the Coho zone, a copper-gold (Cu-Au) porphyry target.

The 8,000-hectare Coho property is located 90 km north of Fort St. James, BC, and 30 km west of Centerra Gold’s Mount Milligan Cu-Au porphyry deposit. The Masu zone, situated along the western boundary, will be examined following results released by Pacific Empire Minerals in January 2026 on the contiguous Trident property. Drilling at Trident’s ‘A zone’ returned 240.0 m of 0.64% Cu, 0.41 g/t Au, and 2.8 g/t Ag, with the Masu zone located 3.3 km east of that intercept. The surface exploration will include prospecting, geological mapping, and a grid soil geochemical survey.

Concurrently, Trailbreaker geologists will ground-truth proposed drill locations at the Coho zone and conduct additional geological mapping. The Coho zone, a Cu-Au porphyry target, has recently undergone property-wide geochemical and geophysical surveys, revealing a coincident chargeability and resistivity anomaly associated with high-grade gold and copper values in surface rock grab samples. The Coho zone itself has never been drilled, although limited historical drilling occurred on the claims.

The Coho property lies within the Quesnel tectonic terrane, a district known for prolific alkalic Cu-Au porphyry deposits. To the north, Pacific Ridge Resources’ Chuchi property returned 382.0 m of 0.19% Cu, 0.12 g/t Au, and 0.47 g/t Ag from its BP zone in 2024 drilling. The Coho zone is defined by a 650 m by 550 m Cu-Au-Ag surface geochemical anomaly within diorite, associated with an ENE-trending fault zone and gabbro dykes. Historic surface grab samples at the Coho zone returned values up to 16.15 g/t Au, 16.35% Cu, and 67.3 g/t Ag.

Trailbreaker’s CEO, Daithi Mac Gearailt, stated, “The Coho Cu-Au porphyry target represents a compelling opportunity, and we're moving purposely toward our September drill program. Our field team is on the ground now, ground-truthing drill locations and systematically sampling territory that has had very little historic exploration.”

The company plans to commence an inaugural diamond drill program at the Coho zone in September 2026, following a May 25, 2026 announcement. A recent airborne ZTEM survey and ground-based induced polarization survey identified an interpreted 400 m by 250 m by 200 m-deep porphyry intrusive complex with a two-limbed IP chargeability high anomaly spanning more than 1.4 km. The Coho zone is interpreted to be situated along the same fault structure that hosts the BP zone on the Chuchi property.

Trailbreaker believes the Coho property may represent a Cu-Au porphyry system similar to surrounding prospects and deposits, potentially part of a cluster along the margin of the Hogem batholith. The company’s field team is now on site to advance exploration efforts ahead of the drill program.
