Trailbreaker Resources Mobilizes Exploration Team to Atsutla Gold Project, Northwestern BC

(TheNewswire)

September 22, 2025 – TheNewswire - Trailbreaker Resources Ltd.(TBK.V) (“Trailbreaker” or “theCompany”) is pleased to announce that an exploration team has beenmobilized to its flagship Atsutla Gold project, located innorthwestern British Columbia (BC).

Trailbreaker’s 100%-owned Atsutla Gold project is located 70 km south of the Yukon-BritishColumbia border and 120 km northwest of the Village of Dease Lake, BC. The project covers over 40,000 hectares (ha) ofground with very limited historic exploration.

Over the past year, Trailbreaker has consolidated keyground within the Atsutla Gold project claim boundary, near theHighlands zone which hosts the highest gold grades sampled on theproperty to date ( up to 630 g/tgold [Au]). The newly acquired groundconsists of 528 ha, 396 ha of which were acquired by recent staking,and 132 ha acquired through a purchase agreement with a claim holder(details below). This area has yet to be explored for gold by theCompany (Figure 1).

Trailbreaker’s team will be performing first-passreconnaissance exploration on the new ground, including geologicalmapping, prospecting, and soil sampling. The team will also beground-truthing drill collar locations within the Highlands zone areain preparation of a future drill program.

Daithi Mac Gearailt, CEO ofTrailbreaker, commented, “Since its discovery in 2020, the Atsutla Gold project hasremained Trailbreaker’s flagship property for good reason. Last yearwe advanced the Swan zone to a drill-ready stage, and we hope to dothis same with the Highlands zone this year. We now have a significantpiece of ground consolidated in the Highlands zone area which, to ourknowledge, is virtually unexplored. I am looking forward to addingmore to the Atsutla Gold project’s story.”

The Highlands zone hosts widespread gold mineralizationwith numerous rock grab samples returning multi-ounce gold and silver(Ag) values over a 750 x 600-metre area. The gold-bearing quartz veinsare confined to shallow-dipping fault structures that have been tracedfor 3.5 km to the north (Snook zone) and 1.5 km to the east (ChristmasCreek zone). This continuity suggests potential for additionalmineralization within the newly consolidated ground west of theHighlands zone. Testing this theory is the primary goal of thisexploration 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 (copper)-Au-Ag target.

Terms of the PurchaseAgreement

On August 26 th , 2025, Trailbreaker signed a purchaseagreement with the claim holder of the aforementioned 132-ha parcel(the “Vendor”). Trailbreaker will pay the Vendor CAD $10,000 toobtain a 100% interest in the property. The Vendor will retain a total2.0% Net Smelter Return (NSR) royalty, which may be brought down to1.0 % through a cash payment of $1,000,000 to the Vendor.

More about the Atsutla Goldproject

The Atsutla Gold project is centered over theregional-scale Teslin-Thibert fault system that marks the contactbetween the Quesnel and Cache Creek terranes. Gold mineralization isassociated with Mesozoic batholitic intrusions that are thepredominant geological unit on the property. Since discovery in2020, Trailbreaker has outlined five significant zonesof gold mineralization on the property, across a span of 26kilometers (Figure 2) . These are:

• Highlands Zone – A 750 m by 600 m area in the western Atsutla Gold projectregion, with veins containing coarse visible gold and assaying up to630 g/t Au and 1,894 g/tAg

• Christmas Creek Zone – Gold-bearing quartz veins 1.5 km east of the HighlandsZone, with rock samples assaying up to 102 g/t Au and 524 g/tAg

• Snook Zone –High-grade veins 3.5 km northeast of the Highlands Zone with rocksamples assaying up to 53.3g/t

• Willie Jack Zone – 1.25 km long gold-in-soil anomaly with soil samplesassaying up to 3.77 g/t Au and rocksamples up to 9.9 g/t Au

• Swan Zone – ACu-Au-Ag porphyry target defined by a 1.5 km x 1.5 km multi-elementsoil geochemical anomaly ( Au-Cu-Ag-arsenic[As]-molybdenum [Mo]-antimony [Sb]-bismuth [Bi]), with rock grab samples grading up to 11.7 g/t Au, 212 g/t Ag,and 0.81% Cu . The geochemical anomalyis coincident with a 2.1 km x 1.4 kmdonut-shaped chargeability high (defined by a 2024 induced polarization survey) as well as a zone ofelevated potassium marked by a magnetic low signature indicated from a2024 airborne magnetic and radiometric survey.
