Trailbreaker Resources Mobilizes To Coho Property For Inaugural Diamond Drill Program

(via TheNewswire) August 31, 2026 – TheNewswire - Trailbreaker Resources Ltd. (TBK.V) (“Trailbreaker” or “the Company”) is pleased to announce the commencement of the maiden drill program at the Company's 8,000-hectare Coho Property in central British Columbia (BC).  The Coho Property is located 90 km north of the Town of Fort St. James, BC and 30 km west of the Mt. Milligan copper-gold (Cu-Au) porphyry deposit (Figure 1). The property is road accessible, with a large network of Forest Service Roads and logging roads within the claims.   Click Image To View Full Size     Figure 1: Location of the Coho Project. Diamond drilling will be conducted at the Coho Zone. Daithi Mac Gearailt, CEO of Trailbreaker, commented, "Mobilization to Coho marks an important step forward for Trailbreaker as we move from surface exploration into the drilling phase. Coho has shown strong potential across multiple targets, and we are eager to put the drill bit into the ground and start generating the data that will define this system.”   The diamond drill program will be focused on the Coho Zone, a Cu-Au porphyry target with recently completed property-wide geochemical and geophysical surveys. The 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. While there has been limited historical drilling within the claim block, the actual Coho Zone has never been drilled. In June, 2026, Trailbreaker conducted a surface exploration program at the Masu Zone, located along the western boundary of the Coho Property. This program targeted the potential extension of the “A Zone” identified by Pacific Empire Minerals (‘PEMC’) on its adjoining Trident Property, from which positive results were released in January 2026. The Trident Property 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) 1 . The Masu Zone is located 3.3 km east of the A Zone*. Results from this program are currently being compiled by Trailbreaker Resources.   More about the Coho Property ( link to presentation ) 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 (see May 26, 2025 news release ). 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) 2 . 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 3 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 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.
