Yukon Metals Corp.: Drilling Expands Near-Surface Copper-Gold Mineralization at the Birch Project
Press Release
VANCOUVER, British Columbia, Nov. 20, 2025– 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.
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 reviewed 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% passing 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.
