14 G/T Au Within 47m of Gold-Bearing Skarn from 26m Depth in 300m Step-Out at Birch Cu-Au Project

Executive Summary

• Yukon Metals released assay results from the final two holes (BR25‑003 and BR25‑006) of its 2025 drill program at the Birch Copper‑Gold Project, expanding the known mineralized footprint by ~300 m to the northeast.
• Hole BR25‑003 intersected a high‑grade gold zone – 1 m @ 14.35 g/t Au (plus 27.9 g/t Ag and 0.60 % Cu) – and a broader 47.4 m interval averaging 0.43 g/t Au, confirming a transition to a gold‑rich skarn domain.
• Hole BR25‑006 added several narrow copper‑gold‑silver skarn intervals, including 0.6 m @ 1.22 % Cu & 40.1 g/t Ag and a deeper 6 m @ 0.19 g/t Au.
• The results support a multi‑style (skarn, epithermal, porphyry) mineral system with strong lateral continuity and justify step‑out drilling to the south where geophysical and geochemical anomalies indicate a potential intrusive center.

Key Details

• Drill Program Scope: 1,685 m HQ diamond core across six holes from four pads.
• Hole BR25‑003 (300 m NE of Hole 1)
• 47.4 m @ 0.43 g/t Au (26.6–74.0 m) – includes 0.5 m @ 3.70 g/t Au, 27.9 g/t Ag, 0.60 % Cu.
• High‑grade interval: 1 m @ 14.35 g/t Au, 2.80 g/t Ag, 0.03 % Cu (71–72 m).
• Deeper zone: 33.8 m @ 0.19 g/t Au (278.7–312.0 m) – includes 2.3 m @ 0.92 g/t Au.
• Hole BR25‑006 (200 m N of Hole 1)
• 0.9 m @ 0.52 % Cu, 21.1 g/t Ag (61.0 m).
• 0.6 m @ 1.22 % Cu, 40.1 g/t Ag (84.5 m).
• 6.0 m @ 0.19 g/t Au (270–276 m).
• Copper‑Equivalent Grades: Calculated using Cu % + (Au g/t × 0.95) + (Ag g/t × 0.0095); e.g., the 14.35 g/t Au interval equals 13.69 % CuEq.
• Surface Sampling (2 km S of drill area): Up to 16 g/t Au, 1,825 g/t Ag, 0.43 % Cu in rock chips over a molybdenum soil anomaly.
• Geological Interpretation: Stacked skarn horizons with gold‑rich upper zone and lower gold‑bearing horizon; geochemical signatures suggest higher‑temperature skarn conditions and proximity to a porphyry source.
• Next Steps
• Step‑out drilling down‑dip to the south targeting the intrusive center indicated by IP, resistivity, and chargeability anomalies.
• Additional infill drilling to improve continuity of the 2025 holes.
• Detailed mapping, IP surveying, and systematic exploration of identified skarn, epithermal, and porphyry targets.

Notable Quotes

“These results are a tremendous finish to the 2025 program…the mineralized system extends well beyond our initial discovery and transitions into a gold‑rich domain carrying the highest‑grade gold we’ve ever seen at Birch.” – Rory Quinn, President & CEO, Yukon Metals Corp.
