Yukon Metals Confirms Large Copper-Bearing System at the AZ Project

Executive Summary

• Yukon Metals Corp. announced assay results from the inaugural 2025 drill program at its 100%-owned AZ Project in Yukon, comprising five drill holes totaling 1,500 meters across two targets: Chair Mountain and the Southeast Prospect.
• The program successfully intersected copper and gold mineralization, validating geological models and suggesting the presence of a larger mineralized system, including porphyry-style indicators at the Southeast Prospect.
• The best intercept was 14.4m at 0.44% Cu, including 1.5m at 0.37 g/t Au in hole AZ25-001, while structural analysis at Chair Mountain provided vectors for future drilling.

Key Details

• Program Overview: Five drill holes totaling 1,500 meters were drilled at the AZ Project, located 36 km south of Beaver Creek, Yukon.
• Best Intercept (Chair Mountain): Hole AZ25-001 intersected 14.4m at 0.44% Cu, including:
  • 1.5m at 0.37 g/t Au and 0.37% Cu.
  • 0.9m at 2.10% Cu.
• Additional Chair Mountain Results:
  • Hole AZ25-003: 23.5m at 0.13% Cu, including 2.7m at 0.46% Cu and 0.5m at 1.50% Cu.
  • Hole AZ25-002: 1.2m at 0.11% Cu and 18.8m at 0.04% Cu.
  • Hole AZ25-005: 9.5m at 0.11% Cu.
• Southeast Prospect Results: Hole AZ25-004 intersected porphyry-style alteration, including:
  • 2.6m at 0.15% Cu and 0.27 g/t Au.
  • 0.8m at 0.11% Cu and 0.15 g/t Au.
  • Identified potassic alteration (K-feldspar, magnetite, silica) below 350m, interpreted as a vector toward a porphyry center.
• Geological Interpretation:
  • Chair Mountain: Dominant SE-striking, steeply-dipping vein orientations consistent with regional extensional stress regimes.
  • Southeast Prospect: Porphyry dikes dip steeply to the southwest; alteration zoning and geochemistry point to proximity to a porphyry center.
• Next Steps: Surface programs planned for September 2025 include contour soil sampling (ICP-MS and hyperspectral analysis), ground-based induced polarization (IP) surveys, and high-resolution airborne magnetic surveys to refine targets for future drilling.

Notable Quotes

• “This is a big system and the right kind of copper system for a large tonnage porphyry,” said Rory Quinn, President & CEO. “At Chair Mountain, we’ve confirmed copper mineralization within a structural corridor, and at the Southeast Prospect we have intersected classic porphyry-style alteration at depth. These initial results validate our proof-of-concept program and confirm that the system is copper-bearing, fertile, and gold-bearing across two distinct areas.”
