Trailbreaker Resources Mobilizes Field Team to Coho Property for Surface Exploration Ahead of September Drill Program
Trailbreaker Resources has mobilized a field team to its Coho copper-gold property in British Columbia for surface exploration, including at the new Masu zone, setting the stage for a September 2026 drill campaign that could test a promising porphyry system near Centerra Gold's Mount Milligan mine.
Trailbreaker Resources Ltd. (TBK.V) has mobilized a field team to its Coho property in central British Columbia to begin a surface exploration program in advance of its planned September 2026 drill campaign, the company announced Monday. The program focuses on two priorities: reconnaissance exploration 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.
The surface exploration program comes on the heels of encouraging results from neighboring properties. Pacific Empire Minerals ('PEMC') reported in January 2026 drilling results on the contiguous Trident property, including 240.0 meters grading 0.64% copper, 0.41 g/t gold, and 2.8 g/t silver at the 'A zone'. The Masu zone on Coho is located just 3.3 kilometers east of that discovery. Trailbreaker's field team will conduct prospecting, geological mapping, and a grid soil geochemical survey at Masu.
“The Coho Cu-Au porphyry target represents a compelling opportunity, and we're moving purposely toward our September drill program,” said Daithi Mac Gearailt, CEO of Trailbreaker, in a statement. “Our field team is on the ground now, ground-truthing drill locations and systematically sampling territory that has had very little historic exploration.”
Trailbreaker's 8,000-hectare Coho property is located 90 kilometers north of Fort St. James and 30 kilometers west of Centerra Gold's Mount Milligan Cu-Au porphyry deposit, a producing mine with current reserves of 1.7 billion pounds copper and 4.3 million ounces gold. The 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 meters of 0.19% copper, 0.12 g/t gold, and 0.47 g/t silver from the BP zone in 2024 drilling.
The Coho zone itself is defined by a 650 by 550 meter Cu-Au-Ag surface rock and soil geochemical anomaly within diorite, associated with an ENE-trending fault zone and gabbro dykes. Historic surface grab samples returned values up to 16.15 g/t gold, 16.35% copper, and 67.3 g/t silver. A 2022 airborne ZTEM survey and a 2023 ground IP survey identified an interpreted 400 by 250 by 200 meter deep porphyry intrusive complex with a two-limbed IP chargeability high spanning more than 1.4 kilometers. The Coho zone has never been drilled.
Trailbreaker acquired the property through an option agreement in May 2025 and has scheduled an inaugural diamond drill program for September 2026. Concurrent with surface exploration at Masu, geologists will ground-truth proposed drill locations at the Coho zone and perform further geological mapping.
“We believe this is shaping up to be an exciting period for Trailbreaker and our shareholders,” Mac Gearailt added.
