Map of Yukon highlighting the Birch project

ABOUT BIRCH

Opportunity

High-grade copper-gold in soil anomaly up to 0.99 g/t Au across 1400m.
Rock chip sampling with values up to 2.42% Cu and 14.1 g/t Au.t Au.
Strong geophysical anomaly aligns with gold and copper anomaly in soil samples and drilling.

YMC owns 100% of the 7,000-hectare property.
Previously owned by Ryan Gold who approached the property as an epithermal gold target.

Location

Within sight of Burwash Landing.

Permitting

First Nations consultation.
Class I Permit: Permit extends to mid-July 2026.

2025 DRILL PROGRAM HIGHLIGHTS

A total of 1,100 metres of diamond drilling has been completed across three pad locations down to depths of up to 400 metres (Figure 7), with all holes intersecting mineralized skarn horizons; assay results are pending.
Near surface mineralization beginning at ~25 metres, and interval widths up to 46 metres in drill core, includes a thick, continuous interval of intensely skarn altered rock from 256.5 to 302.5 metres: true thicknesses currently unknown.
The mineralization style suggests the potential for a large, multistage skarn system developed along the marble–schist contacts and intrusive margins.

GEOLOGY

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.

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.

EXPLORATION

Historic exploration started on Birch in 1972 with the discovery of molybdenum mineralization in quartz veins and stringers in a granodiorite stock in the southern part of the Tyr claims. Massive copper-zinc mineralization was found in sills of quartzite and porphyritic andesite, assays ranged from 0.22%-2.35% Cu and 0.05%-21.5%Zn.

Further work was recommended, but the claims were dropped and not fully restaked again until 2010 and 2011 by Ryan Gold Corp. Ryan Gold Corp ran a large data collection program on the claims with soils, airborne magnetics and radiometrics geophysics, ground IP geophysics and 1294 metres of reconnaissance rotary air blast drilling in 12 drillholes. The claims were subsequently dropped and then re-staked by the Berdahl family.

Prior to the 2024 field season, Yukon Metals utilized previous geochemistry and geophysics to assist in prioritizing targets and develop a comprehensive exploration plan for the season. In 2024, Yukon Metals compiled previous work on the claims and has carried out an initial soil sampling and mapping program to confirm previous work, which had no assay certificates submitted in assessment reports for the soil geochemistry.
