VANCOUVER, BC – Trailbreaker Resources Ltd. (TBK.V) has mobilized a field team to its Coho property in central British Columbia to commence a surface exploration program in advance of a planned September 2026 drill campaign. The program targets two key areas: reconnaissance exploration 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.
The Masu zone, located along the western boundary of the 8,000-hectare Coho property, is being explored following encouraging results from neighboring claims. In January 2026, Pacific Empire Minerals reported drilling results from the adjacent Trident property's 'A zone,' including 240.0 meters grading 0.64% copper, 0.41 g/t gold, and 2.8 g/t silver. The Masu zone lies 3.3 kilometers east of this discovery. Trailbreaker's surface program at Masu will include prospecting, geological mapping, and a grid soil geochemical survey to evaluate its potential.
Concurrently, geologists will ground-truth proposed drill locations at the Coho zone, the property's primary target for the upcoming drill program. The Coho zone is a Cu-Au porphyry target defined by a 650-meter by 550-meter surface geochemical anomaly and a coincident chargeability and resistivity anomaly identified through recent geophysical surveys. Historic surface grab samples at Coho returned values up to 16.15 g/t gold, 16.35% copper, and 67.3 g/t silver. The zone has never been drilled, despite limited historical drilling on the claims.
The Coho property is situated within the Quesnel tectonic terrane, a district known for alkalic Cu-Au porphyry deposits. It is located 30 kilometers west of Centerra Gold's Mount Milligan deposit, a producing mine with reserves of 1.7 billion pounds of copper and 4.3 million ounces of gold. To the north, Pacific Ridge Resources' Chuchi property reported 382 meters grading 0.19% copper and 0.12 g/t gold from its BP zone in 2024. Trailbreaker believes the Coho zone may represent a similar porphyry system, potentially part of a cluster along the margin of the Hogem batholith.
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 surface program is expected to refine drill targets ahead of the inaugural diamond drill program scheduled for September 2026. Trailbreaker acquired the Coho property through an option agreement in May 2025, with the option to earn a 100% interest. The company continues to advance exploration in mining-friendly British Columbia, leveraging a portfolio of quality mineral properties.
