Trailbreaker Resources Ltd. (TBK.V) has completed its Phase One diamond drill program at the Coho Property in central British Columbia, marking the first time the Coho Zone itself has been drilled. The program consisted of seven holes totaling 2,667 metres, testing an area of 1,000 by 800 metres and a vertical extent of 474 metres. The 8,000-hectare property is a copper-gold porphyry target located 90 kilometres north of Fort St. James and 30 kilometres west of the Mt. Milligan porphyry deposit, and is road accessible via a network of Forest Service Roads and logging roads.
The significance of the program lies in its targeting: the Coho Zone hosts recently identified coincident induced polarization (IP) chargeability and resistivity anomalies associated with high-grade gold and copper values from surface rock grab samples, yet had never been drilled before Trailbreaker’s 2026 campaign. The company also completed a concurrent IP survey of four east-west lines totaling fourteen line-kilometres, three of which were spaced 200 metres apart and positioned 200 metres north of the historic 2023 survey, while one line confirmed historic results. Preliminary survey results were used to target a chargeability anomaly and interpreted structure with hole CH-26-07, drilled 500 metres north of the King showing area. Other holes targeted a sizable 400 by 800 metre IP feature, the Chinook showing with historic channel samples grading 0.08 g/t Au and 0.29% Cu over 11.4 metres, and an east-west fault. A total of 1,415 drill core samples, including standard reference material and blanks, were submitted to Bureau Veritas’ lab in Vancouver, with assay results expected in late 2026 or early 2027. Full collar details are available in Table 1: Drill collar details for the 2026 program, and the drill plan is shown in Figure 1: 2026 drill plan map at the Coho Property.
The implications extend beyond Coho. Trailbreaker also completed a six-hole, 1,684-metre drill program in early August at its Atsutla Gold Project in northwestern BC, targeting the Highlands Zone, a high-grade vein-hosted gold target, and the Swan Zone, a copper-gold-silver-molybdenum porphyry target, spaced 26 kilometres apart. Assays from that program remain pending. Upon completion of drilling, the company contracted Eagle Mapping for an airborne property-wide LiDAR survey to aid in mapping lithologies and locating veins, faults, geological contacts, and dikes, and contracted Aurora Geosciences Ltd. to complete an independent NI 43-101 technical report to replace a previous report filed in December 2022. Details of the Atsutla program are available in the August 10, 2026 news release, with drill plan maps in Figure 3: 2026 drill plan map at the Highlands Zone, Atsutla Gold Project and Figure 4: 2026 drill plan map at the Swan Zone, Atsutla Gold Project.
At the Coho Property’s Masu Zone, along the western boundary, Trailbreaker conducted a June 2026 surface exploration program targeting the potential eastward extension of the “A Zone” identified by Pacific Empire Minerals on its adjoining Trident Property, where drilling returned 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 kilometres east of the A Zone, and results from Trailbreaker’s program are being compiled. President and CEO Daithi Mac Gearailt said the company is well positioned to provide a steady flow of news through the remainder of 2026 and early 2027, with assay results expected soon from diamond drilling of the Highlands gold and Swan copper-molybdenum porphyry targets.
