Trailbreaker Resources Provides Corporate Update

(TheNewswire)

September 15, 2025 – TheNewsire - Trailbreaker Resources Ltd.(TBK.V) (“Trailbreaker” or “theCompany”) is pleased to provide the following corporate updateon its gold (Au), copper-gold (Cu-Au), and copper-molybdenum (Cu-Mo)projects in British Columbia (BC) and Yukon Territory.

Trailbreaker is currently focussed on three projects inBC: the Liberty Cu-Mo porphyry project and Coho Cu-Au porphyryproject, both in central BC, the Atsutla high-grade Au and porphyryCu-Au-silver (Ag) project in northwestern BC.

Atsutla Gold Project

The Atsutla Gold project is a newly discoveredhigh-grade gold project 120 km northwest of Dease Lake, BC. Inaddition to high-grade vein-hosted gold, the project also hosts aCu-Au-Ag porphyry target called the Swan zone, which was furtheroutlined through geophysical surveying in 2024 (see October 7, 2024 newsrelease ). Over the past three months,Trailbreaker consolidated key ground within the Atsutla Gold propertyclaim boundary, particularly near the Highlands zone which hosts thehighest gold grades sampled on the property to date ( up to 630 g/t Au in grabsamples ).

The Company plans to conduct a first-pass explorationprogram over the newly acquired ground by the end of this fieldseason, in addition to ground-truthing of drill collar locations inpreparation of a future drill program.

The Highlands zone hostswidespread gold mineralization with numerous rock grab samplesreturning multi-ounce gold and silver values over a 750 x 600-meterarea. The gold-bearing quartz veins are confined to shallow-dippingfault structures that have been traced for 3.5 km to the north (Snookzone) and 2 km to the east (Christmas Creek zone). This continuitysuggests potential for additional mineralization within the newlyconsolidated ground west of the Highlands zone. The team is excited totest this theory during the upcoming exploration program.

The Atsutla Gold project is fully permitted fordrilling, focusing on two separate targets representing distinctdeposit settings, neither of which have ever been drilled. TheHighlands zone represents a brand-new high-grade orogenic golddiscovery, while the Swan zone, situated 26 km to southeast,represents a porphyry Cu-Au-Ag target.

Liberty Cu-Mo Project

Throughout 2024 and 2025, Trailbreaker advanced itsLiberty Cu-Mo porphyry project, located 60 km northwest of Quesnel,BC. In 2024, the Company completed a seven-hole, 2,442 m diamonddrilling program followed-up by an extensive soil geochemical program,an induced polarization (IP) geophysical survey, and an airborneelectromagnetic (ZTEM) survey. Throughout this process, the propertywas expanded twice through additional claim staking, increasing from5,054 hectares to 9,453 hectares in size.

Favourable drill results and combined interpretation ofthe IP and ZTEM data defined a significant target area for a phase 2drill program, which was initially planned for May-June, 2025 (see Jan 13, 2025 newsrelease ).  However, due to the significantsize increase of the claim package, and the magnitude of the planneddrill program, additional archaeological studies and environmentalassessments were required which have beencompleted and are currently under review. As such, approval for thedrill permit has been delayed.

Coho Cu-Au Property

In May, 2025, Trailbreaker acquired the Coho property,a Cu-Au porphyry target located in central BC, 30 km west ofthe Mount Milligan mine, and directly adjacent to Pacific RidgeExploration’s Chuchi Cu-Au porphyry deposit (see May 26, 2025 news release ). The Company considersthe Coho property to be one of the more advanced projects in itsportfolio. The priority target, the Coho zone, has been advancedthrough recent IP and airborne electromagnetic (EM) surveys, and hasnever been drilled.

Due to the size and scope of the project, Trailbreaker is planning anaggressive drill program. The Company is currently modelling historic(2022-2023) geophysical data and is compiling historic geochemicaldata to aid in drill targeting. While the Coho propertyis currently permitted for drilling under the previous operator(Pacific Ridge Exploration Ltd.), Trailbreaker has chosen to apply fora new separate drill permit that will comprise a much larger scope ofexploration. The new application is for a 5-year area-based permitthat will include up to 50 drill sites. The permit process is wellunderway, and Trailbreaker is working closely with the BC governmentand local First Nations to finalize the process.

Other Projects

In July, 2025, Trailbreaker announced the acquisitionof the Wheaton Goldproperty , an orogenic gold prospect located 60km east of Dease Lake, BC (see July 7, 2025 newsrelease ). The property covers the headwatersof multiple placer gold-bearing creeks, including Alice Shea Creek,source of the famous 52- troy oz ‘Turnagain nugget’. The Companyis currently mobilizing for a 2025 surface exploration program to testmultiple targets on the project.

Trailbreaker is also pleased to announce that the drillpermit for its Castle Rockproperty on Vancouver Island has been approved.The Castle Rock property is an early-stage Cu-Au porphyry prospectsituated on northern Vancouver Island, approximately 70 km northwestof Campbell River, BC.  The company has advanced the project throughmultiple surface exploration programs from 2022 to 2024 (see August 12, 2024 newsrelease ). The newly received 5-yeararea-based permit includes up to 40 drill sites and 40 line-km ofground geophysics (such as IP, magnetic, or EM). The Company iscurrently planning the next steps for this project.

Trailbreaker remains committed to maintaining apipeline of high-quality exploration projects throughout BC and theYukon (Figure 1). These include McMurdo property near Golden, BC, the Eakin Creekproperty near Clearwater, BC, the Eagle Lake property east of Williams Lake, BC, the Sheldon property north of Ross River, YT, andthe Plateauproperty east of Mayo, YT.
