DRILLING EXPANDS NEAR-SURFACE COPPER-GOLD
MINERALIZATION AT THE BIRCH PROJECT
November 20, 2025 – Vancouver, British Columbia – Yukon Metals Corp. (CSE: YMC,
FSE: E770, OTCQB: YMMCF) (“Yukon Metals” or the “Company) is pleased to announce
results from the 2025 drill program at its 100% owned Birch Copper-Gold Project (“Birch”),
located 65 kilometers northeast of Burwash Landing, Yukon. The Company has received
assays from two additional drill holes, BR25-002 and BR25 -004, showing a 500m lateral
extension to skarn mineralization.
Highlights:
• Drilling at Birch continues to expand near-surface mineralization, with BR25-
002 returning 10.1m of 0.21% Cu (0.30% CuEq) from only 58.6 m depth,
including 1.8 m 1.12% Cu (1.51% CuEq).
• Step-out drilling confirms lateral continuity of the skarn system, with BR25-004,
500m east of the earlier holes, intersecting 16.0 m of 0.20% Cu (0.28% CuEq),
including a high-grade interval of 0.89% Cu (1.13% CuEq) over 1.0m.
• Borehole data shows copper and gold-bearing skarn horizons encountered in
BR25-001 are present at shallower levels in BR25-002 and BR25-004.
“These results show that the mineralized skarn horizons are both persistent and occurring
closer to surface, with solid copper grades across multiple intervals ,” said Rory Quinn,
President and CEO. “Confirming continuity between widely spaced holes strengthens our
understanding of the system as we await further assays.”
Drill Results
The 2025 drill program at Birch consisted of 1,685m of HQ diamond drill core in six holes
off 4 pads (Figure 1). Highlights from Hole BR25-002 and 4:
• 10.1m of 0.21% Cu (0.30% CuEq*) from 58.6 to 68.6m and 1.8m of 1.12% Cu (1.51%
CuEq*) from 124.7-126.5m in BR25-002.
• 16.0m of 0.20% Cu (0.28 % CuEq**) from 97.0 to 113.0m, including 1.0m of 0.89%
Cu (1.13% CuEq*) from 102.0 to 103.0m in BR25-004.

• BR25-002 intersected copper and gold -bearing skarn horizons similar to those
encountered in BR25 -001, but at shallower depths. The near -surface high -grade
zone is hosted within foliated skarn units containing disseminated and banded
sulfides.
• BR25-004 drilled 500m east of holes 1 and 2, demonstrates that the marble and
skarn horizons, and associated copper mineralization, are laterally continuous to the
west.

Notes: True widths are not yet known but are estimated to be near true thickness based on current geological
interpretation.*Copper equivalent (CuEq %) values have been calculated using the formula: CuEq % = Cu % + (Au g/t ×
0.95) + (Ag g/t x 0.0095), based on metal prices of US $4.00/lb Cu, $3,000/oz Au, US $40/oz Ag. Recovery factors of
92% copper, 80% gold, and 60% silver were assumed based on a review of similar projects. No metallurgical test work
has yet been completed at Birch.

About the Birch Project
Yukon Metals owns 100% of the helicopter -accessed Birch project located 65 kilometres
northeast of the community of Burwash Landing. The Birch project area is dominated by frost-
heaved boulders in unglaciated terrain, with outcrop present on steeper ridges . The project
lies predominantly within the Finlayson assemblage of the Yukon-Tanana Terrane, consisting
of variably carbonaceous schist and quartzite, marble, garnet amphibolite and rare
metaplutonic rocks.
The Yukon-Tanana Terrane structurally overlies the Ruby Range Batholith which is regionally
mapped in the northeastern portion of the property occurring as Ruby Range quartz-feldspar
porphyry and Rhyolite Creek porphyry and intermediate and felsic volcanic rock (Israel et.
Al., 2011).
Project-level mapping indicates the geology of the area is comprised of schists and marble
units, moderately to strongly oxidised felsic intrusive, and patchy oxidised porphyritic rhyolite
dykes.
Yukon-based and Local First Nation Contractors Engaged
Drill pad construction at the Birch Property was completed by Minconsult in partnership with
Vision Quest Drilling, a Kluane First Nation citizen -owned company. Helicopter support is
being provided by Yukon-based Capital Helicopters. Drilling services were contracted to New
Age Drilling in partnership with Vision Quest Drilling. Camp services were delivered by
Käganì, a Kluane First Nation citizen -owned enterprise, in partnership with long -standing
Yukon-based exploration contractor Archer Cathro.

QAQC
All diamond drill core from the 2025 program at the Birch Project was logged, photographed,
and sawn in half using a diamond blade core saw. One half of the core was submitted for
geochemical analysis, while the other half was retained in secure storage for reference.
Sampling intervals were determined based on geological boundaries and typically ranged
0.3- 1.5 meters. Control samples comprised approximately 10% of all samples submitted,
including certified reference standards, analytical blanks, field duplicates, and preparation
duplicates. QA/QC results were r eviewed in real time, and all data have been verified as
meeting acceptable thresholds for accuracy, precision, and contamination before inclusion in
this release.
Drill core and rock samples were sent to ALS Minerals for analysis with sample preparation
in Whitehorse, Yukon and analysis in North Vancouver, British Columbia. Samples were
prepared by crush to 70% passing 2mm, 250g split pulverised better than 85% pass ing 75
microns (Prep-31A). Pulp samples were analysed for 34 elements by four acid digestion and
ICP-AES (ME-ICP61). All samples were analyzed for gold by fire assay and AAS with a 50g
nominal sample weight (Au-AA24). Samples over 10,000 g/t Cu were assayed by Ore grade
Cu- Four Acid (Cu-OG62).
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.
