Trailbreaker Resources Ltd. (TBK.V) has announced the mobilization of a field team to its Coho property in central British Columbia to commence a surface exploration program, setting the stage for a planned drill campaign in September 2026. The program focuses on two key areas: reconnaissance along the property's 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.
This development is significant for the mining industry as it follows encouraging results from neighboring properties. The Masu zone is located just 3.3 km east of the 'A zone' on the contiguous Trident property, where drilling by Pacific Empire Minerals ('PEMC') in January 2026 returned 240.0 meters of 0.64% copper, 0.41 g/t gold, and 2.8 g/t silver (source). The surface exploration at Masu will involve prospecting, geological mapping, and a grid soil geochemical survey to follow up on these results.
At the Coho zone, the company plans to ground-truth proposed drill locations and conduct additional geological mapping. This zone has never been drilled, despite hosting a coincident chargeability and resistivity anomaly identified through recent geophysical surveys, along with high-grade gold and copper values from surface rock grab samples. The Coho zone is defined by a 650 m x 550 m Cu-Au-Ag geochemical anomaly within diorite, associated with an ENE-trending fault zone and gabbro dykes. Historic grab samples returned values up to 16.15 g/t gold, 16.35% copper, and 67.3 g/t silver.
“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. “Our field team is on the ground now, ground-truthing drill locations and systematically sampling territory that has had very little historic exploration.”
The Coho property spans 8,000 hectares and is located 90 km north of Fort St. James, BC, and 30 km west of Centerra Gold’s Mount Milligan Cu-Au porphyry deposit, a producing mine with reserves of 1.7 billion pounds copper and 4.3 million ounces gold (source). To the north lies Pacific Ridge Resources’ Chuchi property, where 2024 drilling returned 382.0 meters of 0.19% copper, 0.12 g/t gold, and 0.47 g/t silver (source). The Coho zone is interpreted to be situated along the same Valley/Redline fault structure that hosts the BP zone at Chuchi, suggesting potential for a cluster of deposits similar to other alkalic Cu-Au porphyry systems in the region.
Trailbreaker acquired the Coho property through an option agreement in May 2025 and has the option to earn a 100% interest. The company's exploration efforts are focused on a district known for prolific alkalic Cu-Au porphyry deposits, and the upcoming drill program will test the Coho zone for the first time. The results from the current surface exploration will help refine drill targets and could significantly impact the project's valuation and the company's share price. For the mining industry, this project represents another potential addition to the rich mineral endowment of the Quesnel tectonic terrane.
