Trailbreaker Resources Mobilizes to Coho Property for Surface Exploration Program in Advance of September Drill Program
Trailbreaker Resources Ltd. has mobilized a field team to its Coho property in central British Columbia to begin a surface exploration program in advance of its upcoming September 2026 drill campaign. The program has two priorities: reconnaissance exploration along the property's underexplored western boundary (the ‘Masu zone’), and ground-truthing of drill hole locations at the Coho zone, a copper-gold (Cu-Au) porphyry target. Trailbreaker’s 8,000-hectare Coho property is located 90 km north of the Town of Fort St. James, BC and 30 km west of the Mt. Milligan Cu-Au porphyry deposit. The surface exploration program will be conducted at the Masu zone, located along the western boundary of the Coho property. This program will follow up on results released by Pacific Empire Minerals in January 2026 on the Trident property, which is contiguous with Coho’s western border. Drilling at the Trident property’s ‘A zone’ returned results including 240.0 m of 0.64% Cu, 0.41 g/t Au, and 2.8 g/t silver (Ag). The Masu zone is located 3.3 km east of the A zone. The proposed surface exploration program will consist of prospecting, geological mapping, and a grid soil geochemical survey. On May 25, 2026, Trailbreaker announced plans to drill the property’s primary target, the Coho zone, with an inaugural diamond drill program to commence in September 2026. The Coho zone is a Cu-Au porphyry target with recently completed property-wide geochemical and geophysical surveys. The zone hosts a recently identified coincident chargeability and resistivity anomaly, associated with high-grade gold and copper values from surface rock grab samples. Concurrent to exploring the Masu zone, Trailbreaker geologists will ground-truth proposed drill locations at the Coho zone and perform further geological mapping. The 8,000-hectare Coho property was acquired by Trailbreaker through an option agreement signed in May 2025 whereby Trailbreaker has the option to acquire a 100% interest. The priority target is the Coho zone, a drill-ready Cu-Au porphyry target with recently completed property-wide geochemical and geophysical surveys. The zone hosts a recently identified coincident chargeability and resistivity anomaly, associated with high-grade gold and copper values from surface rock grab samples. While there has been limited historical drilling on the claims, the actual Coho zone has never been drilled. Located within the Quesnel tectonic terrane, the Coho property is situated in a district known for prolific alkalic Cu-Au porphyry deposits and prospects. The property is located 30 km west of Centerra Gold’s Mount Milligan Cu-Au porphyry deposit, a producing mine with current reserves of 1.7 B lbs Cu and 4.3 Moz Au (470,332 kt grading 0.17% Cu and 0.28 g/t Au). To the north lies Pacific Ridge Resources’ Chuchi property, where 2024 drilling returned 382.0 m of 0.19% Cu, 0.12 g/t Au, and 0.47 g/t Ag from the BP zone. The Coho zone is defined by a 650 m x 550 m Cu-Au-Ag surface rock and soil geochemical anomaly within diorite, and is spatially associated with an ENE-trending fault zone (the Coho fault) and gabbro dykes. Two additional faults, the Valley and Redline faults, extend south from the BP zone (Chuchi property) onto the Coho property and converge with the Coho fault at the Coho zone. 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. A recent (2022) airborne ZTEM (Z-axis Tipper electromagnetic) survey centered on the Coho zone, followed by a 2023 ground-based induced polarization (IP) survey, identified an interpreted 400 m x 250 m x 200 m-deep porphyry intrusive complex (3D ZTEM anomaly) with a two-limbed IP chargeability high anomaly that spans more than 1.4 km. The Coho zone is located 4.5 km south of the BP zone (Chuchi property) and is currently interpreted to be situated along the same Valley/Redline fault structure that hosts the BP zone. Alkalic porphyry deposits commonly occur in clusters and Trailbreaker’s team believes the Coho property, in particular the Coho zone, may represent a Cu-Au porphyry system similar to the surrounding prospects and deposits. Trailbreaker has interpreted this system to be part of a cluster of deposits found along the margin of the Hogem batholith.
