YUKON METALS COMMENCES INAUGURAL DRILL PROGRAM AT

ITS STAR RIVER PROJECT

August 25, 2025 – Vancouver, British Columbia – Yukon Metals Corp. (CSE: YMC, FSE: E770,

OTCQB: YMMCF) (“Yukon Metals” or the “Company) is pleased to provide an update from its

inaugural drill program at the 100%-owned, road-accessible, 720-hectare Star River Project located

near Ross River, Yukon. The first holes of the planned diamond drilling program have successfully

intersected zones of structurally controlled veining in quartzite and dolostone units near the F2

showing area. Core photos from these early holes are included below in this release.

Highlights:

• Initial drillholes intersected quartzite and dolostone with vein swarms containing

pyrite, arsenopyrite, quartz, ankerite, and galena.

• Drilling is focused on a strong gravity anomaly coinciding with a Time-Domain

Electromagnetic conductor near the historic F2 and Canyon showings.

• Core photos presented in this release show vein textures and sulfide mineralization

consistent with surface observations.

"We are highly encouraged by the early visuals from our initial holes into the F2 target. The

intersection of sulfide -rich vein swarms in both quartzite and dolostone supports our geological

model and validates the targeting approach. With core in -hand showing the right minerals and

structures, we’re optimistic as we continue drilling into this promising system ,” said Rory Quinn,

President and CEO of Yukon Metals. “Yukon Metals is also well underway with the drill program at

its Birch copper-gold project, which will be the subject of a separate news release.”

Building on the strong geophysical results and the success of the previous seasons’ rock -chip

sampling, which returned multiple samples over 1,000 g/t silver and gold up to 101 g/t , the

Company has initiated drilling at a high-priority target in the southern portion of the property. This

area hosts a significant gravity anomaly extending approximately 800 meters north–south, which

coincides with a Time -Domain Electromagnetic (TDEM) high near the historic F2 and Canyon

showings. The overlap of these geophysical signatures suggests a major geological feature, and

drilling is designed to determine whether it represents a favorable host rock or structural control

on mineralization.

Initial holes have intersected vein swarms within quartzite and dolostone lithologies. These swarms

host pyrite, arsenopyrite, galena, quartz, and ankerite, with locally brecciated textures. Core photos

included in this release highlight several mineralize d intervals, which are consistent with a

structurally focused mineralizing system.

Additional Exploration Activities

In addition to drilling, a high -resolution UAV drone magnetic survey will be conducted across the

property. This survey, alongside detailed geological mapping and rock geochemical sampling, will

refine the structural interpretation and follow up on anomalous 2024 rock-chip samples, including

a sample returning 10,936 g/t Ag.

A gravity infill survey over the Saddle Zone, where a 2024 TDEM anomaly was previously identified,

was completed earlier in the season. This dataset is being integrated with drill and magnetic data

to better resolve subsurface features and refine future drill targets.

About the Star River Project

Yukon Metals owns 100% of the Star River base and precious metals project accessible by all -

season road from the Robert Campbell Highway and adjacent to the former Ketza Mine haul road.

The project is host to multiple showings of polymetallic carbonate rep lacement mineralization and

quartz-sulphide veins first discovered in the 1950s. Remnants of underground and surface workings

using historical exploration techniques are visible around much of the property and tied together with

previously established access roads and trails branching from the Ketza Mine Road. Yukon Metals

has an exploration agreement in place with Ross River Dene Council for the Star River Project.

Yukon-based and Local First Nation Contractors Engaged

Helicopter support is being provided by Yukon -based Capital Helicopters, with drilling services

contracted to Platinum Drilling. Camp services are being delivered by Käganì, a Kluane First Nation

citizen-owned enterprise, in partnership with long -standing Yukon-based exploration contractor

Archer Cathro.

QAQC

Diamond drill core from the 2025 program at the Star River Project is in the process of being logged,

photographed, and sawn in half using a diamond -blade core saw. One half of the core will be

submitted for geochemical analysis, while the other half will be retained in secure storage for

reference.

Prospecting rock samples in 2024 were sent to ALS Minerals for analysis with sample preparation in

Whitehorse, Yukon and analysis in North Vancouver, British Columbia.

Rock samples taken while prospecting referenced in this release are selective in nature and collected

to determine the presence or absence of mineralization and may not be representative of the

mineralization hosted on the project.

of prospecting by the Berdahl family — the same team behind Snowline Gold’s portfolio of primary

gold assets. The Yukon Metals portfolio consists primarily of copper-gold and silver-lead-zinc assets,

with a substantial gold and silver component.

The Yukon

The Yukon remains one of the world’s last underexplored mineral belts, offering exceptional discovery

potential. The Territory is home to a highly skilled and conscientious local workforce, shaped by

generations of exploration experience coupled with a dee p respect for the land. Recent major

discoveries with local roots, such as Snowline Gold’s Rogue Project - Valley Discovery, highlight the

Yukon’s potential to generate fresh district-scale mining opportunities.
