TRAILBREAKER RESOURCES MOBILIZES TO COHO PROPERTY FOR SURFACE EXPLORATION PROGRAM IN ADVANCE OF SEPTEMBER DRILL PROGRAM

Trailbreaker Resources Ltd. has mobilized a field team to its Coho property in central British Columbia to begin a surface exploration program in advance of its coming September, 2026, drill campaign. The program has two priorities: reconnaissance exploration along the property's underexplored western boundary (the Masu zone) and ground truthing of drill hole locations at the Coho zone, a copper-gold porphyry target.

Daithi MacGearailt, chief executive officer of Trailbreaker, commented: "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. We believe this is shaping up to be an exciting period for Trailbreaker and our shareholders."

Trailbreaker's 8,000-hectare Coho property is located 90 kilometres north of the town of Fort St. James, B.C., and 30 km west of the Mount Milligan Cu-Au porphyry deposit. The surface exploration program will be conducted at the Masu zone, located along the western boundary of the Coho property. This program will follow up on results released by Pacific Empire Minerals in January, 2026, on the Trident property, which is contiguous with Coho's western border. Drilling at the Trident property's A zone returned results including 240.0 metres of 0.64 per cent copper, 0.41 gram per tonne gold and 2.8 g/t silver. The Masu zone is located 3.3 km east of the A zone. The proposed surface exploration program will consist of prospecting, geological mapping and a grid soil geochemical survey.

On May 25, 2026, Trailbreaker announced plans to drill the property's primary target, the Coho zone, with an inaugural diamond drill program to commence in September, 2026. The Coho zone is a Cu-Au porphyry target with recently completed property-wide geochemical and geophysical surveys. The zone hosts a recently identified coincident chargeability and resistivity anomaly, associated with high-grade gold and copper values from surface rock grab samples. Concurrent to exploring the Masu zone, Trailbreaker geologists will ground-truth proposed drill locations at the Coho zone and perform further geological mapping.

About the Coho property

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-per-cent interest (see May 26, 2025, news release). The priority target is the Coho zone, a drill-ready Cu-Au porphyry target with recently completed property-wide geochemical and geophysical surveys. The zone hosts a recently identified coincident chargeability and resistivity anomaly, associated with high-grade gold and copper values from surface rock grab samples. While there has been limited historical drilling on the claims, the actual Coho zone has never been drilled.

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 billion pounds Cu and 4.3 million ounces Au (470,332,000 tonnes grading 0.17 per cent Cu and 0.28 g/t Au). To the north lies Pacific Ridge Resources' Chuchi property, where 2024 drilling returned 382.0 m of 0.19 per cent Cu, 0.12 g/t Au and 0.47 g/t Ag from the BP zone.

The Coho zone is defined by a 650-metre-by-550-metre Cu-Au-Ag surface rock and soil geochemical anomaly within diorite, and is spatially associated with an east-northeast-trending fault zone (the Coho fault) and gabbro dikes. 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 per cent Cu and 67.3 g/t Ag.

A recent (2022) airborne ZTEM (Z-axis Tipper electromagnetic) survey centred on the Coho zone, followed by a 2023 ground-based induced polarization survey, identified an interpreted 400-metre-by-250-metre-by-200-metre-deep porphyry intrusive complex (3-D 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.
