Slide 1: Coho Property: Drill-Ready & Underexplored Cu-Au Porphyry Project
TSX.V: TBK COHO An PROPERTY under-explored, road accessible A DRILL-READY & UNDEREXPLORED Cu-Au Cu-Au Porphyry Project COHO PROPERTY PORPHYRY PROJECT IN BRITISH COLUMBIA
Slide 2: Project Highlights: Coho Property Overview
PROJECT HIGHLIGHTS COHO PROPERTY overview LOCATION – Situated in central British Columbia, near an established copper-gold (Cu-Au) porphyry deposit ACCESS – Accessible by road, approximately a 2.5-hour drive north of Fort St. James, BC INFRASTRUCTURE – Located just 30 km northwest of the Mt. Milliga
Slide 3: Location and Infrastructure
LOCATIONAND LOCATION ANDINFRASTRUCTUR INFRASTRUCTURE E • A road accessible porphyry project that remains underexplored with drill-ready targets. COHO Mackenzie • Located 30 km northwest of the operating Mt. MT MILLIGAN MINE Milligan mine and powerline infrastructure. • Accessed via a 100 km drive fr
Slide 4: Deposit Type
DEPOSIT TYPE Characteristics of Alkalic Cu-Au Porphyry Systems: Operating Mine – Alkalic Cu-Au Porphyry • Occur as copper and gold-rich porphyry systems. The gold content enhances the economic viability of these deposits. Quesnel Tectonic Terrane • Represent one of BC’s most productive deposit setti
Slide 5: Coho Property Mining District
MINING DISTRICT • The 8,000-ha Coho property lies within the underexplored northern half of the Quesnel terrane where Centerra Gold Corp. operates both the Kemess and Mt. Milligan Cu-Au mines. • Several significant projects are also being advanced in this area, such as Thesis Gold Corp.’s Lawyers pr
Slide 6: Regional Geology
REGIONAL GEOLOGY • Both the Coho and Chuchi properties are located at the southeastern margin of the Jurassic Hogem batholith. The Mt. Milligan mine (located 30 km southeast) is associated with intrusive outliers sourced from the Hogem batholith. • The Mt. Milligan and Chuchi properties host Cu-Au m
Slide 7: Geology
GEOLOGY The Coho property is underlain by Lower Jurassic volcanic and sedimentary rocks of the Takla Group and intruded by Jurassic monzodiorite and syenite porphyry intrusions associated with the margin of the Hogem batholith. Mineralization occurs near the intersection between the Valley, Redline,
Slide 8: Coho Zone
COHO ZONE • The Coho zone is a recently (2020-2023) defined, drill-ready Cu-Au porphyry target situated just 3.0 km south of the Chuchi deposit. This zone is the priority target on the property and has never been drilled. • The Coho zone is defined by: • A 650 m x 550 m Cu-Au-Ag surface geochemical
Slide 9: Mount Milligan Analogy
MOUNT MILLIGAN ANALOGY The Coho property has strong potential to host additional mineralized porphyry 50 million tonnes stocks that are associated with the Chuchi deposit 3 km to the north. This porphyry cluster model is analogous to what occurs at the Mount Milligan deposit situated 30 km to the so

Slide 11: Coho Property – Exploration History
COHO PROPERTY – EXPLORATION HISTORY Work on what is now called the Coho property dates back to the 1960s and historic work includes property-wide soil geochemical surveys, geophysical surveys, and 20 widely-spaced, shallow diamond drill holes. The historic drilling mainly focused on expanding the Ch
Slide 12: Soil Geochemistry
SOIL GEOCHEMISTRY Property-wide soil sampling grids have led to the identification of several kilometric-scale copper OPEN anomalies, with some remaining open. OPEN Many of the soil anomalies have not been followed up with OPEN prospecting and represent potential for new discoveries. The soil anomal
Slide 13: Rock Geochemistry
ROCK GEOCHEMISTRY Recent prospecting (following up on historic copper soil anomalies) has outlined several zones containing high-grade Cu-Au porphyry-style mineralization. The Coho zone represents the most significant zone; however other areas show strong gold mineralization with values up to 19 g/t
Slide 14: Coho Zone - Geochemistry
COHO ZONE - GEOCHEMISTRY Features of the Coho zone include: COHO ZONE • Consistently strong Cu-Au soil and 1990 Noranda rock grab samples covering a 650 x drill holes 500-metre area that lacks outcrop exposure (135 rock grab samples averaging 1.00% Cu and 0.79 g/t Au). Soil anomaly remains OPEN • Si

Slide 20: Conductivity
• Classic porphyry geophysical response, where alteration forms a conductive halo around an altered intrusion (“donut-shape”) • The surrounding alteration may be a sericite-clay assemblage with disseminated pyrite, also forming a chargeability high (as seen on both ends of the IP lines) • Moderate c

COHO ZONE – CHARGEABILITY ANOMALIES (3D VIEW) • In 2025, Trailbreaker re-modelled (inverted) the historic IP data. • Using the inverted IP, combined with the historic ZTEM and geochemical data, Trailbreaker has proposed a series of drill holes to test the Coho zone • The inaugural drill program will
Slide 22: Summary Coho Property
