- Yukon Metals Corp. (CSE:YMC) intersected copper and gold mineralization at both Chair Mountain and the Southeast Prospect during its inaugural 2025 drill program at the AZ Project, confirming a potentially large mineralized system.
- Chair Mountain drilling returned up to 2.10 per cent Cu and 0.37 g/t Au, while Southeast Prospect revealed porphyry-style alteration, indicating proximity to a porphyry center despite lower grades.
- Next steps include soil sampling, geophysical surveys, and hyperspectral analysis to refine exploration targets and vector toward concealed mineralization across the 131 km² property
- Yukon Metals stock (CSE:YMC) last traded at $0.84
Yukon Metals (CSE:YMC) unearthed promising assay results from its inaugural 2025 drill program at the 100 per cent-owned AZ Project, a 131-square-kilometre property located approximately 6 kilometres west of the Alaska Highway and 36 kilometres south of Beaver Creek, Yukon.

The first-pass drill campaign, comprising five holes totalling 1,500 metres, targeted two newly identified zones: Chair Mountain and the Southeast Prospect. Results from both areas confirmed copper and gold mineralization, supporting the company’s geological models and suggesting the potential for a larger mineralized system.
Chair Mountain: Copper system confirmed
Four of the five drill holes (AZ25-001, -002, -003, and -005) were completed at Chair Mountain, testing near-surface copper showings hosted in quartz–carbonate–chalcopyrite veins and a fault zone between basalt volcanics and overlying volcaniclastic/siliciclastic rocks.
Hole AZ25-001 returned 14.4 metres grading 0.44 per cent Cu, including a high-grade subinterval of 0.9 metres at 2.10 per cent Cu. Hole AZ25-003 intersected 23.5 metres at 0.13 per cent Cu. Gold values up to 0.37 g/t Au were also reported near surface in AZ25-001. Structural analysis revealed SE-striking, steeply-dipping veins consistent with regional extensional stress regimes.
“This is a big system and the right kind of copper system for a large tonnage porphyry,” Rory Quinn, president and CEO of Yukon Metals said in a news release. “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. With clear geological vectors now in hand, our next phase of drilling will focus on stepping out toward the core of the porphyry system and we will conclude the season with follow-up soil sampling and induced polarization geophysics.”
Southeast Prospect: Porphyry potential emerges
Hole AZ25-004 targeted a zone of alteration and chalcopyrite mineralization within a dioritic body intruded by porphyry dikes. Although the hole did not return economic copper grades, it revealed significant porphyry-style alteration, including potassic assemblages of K-feldspar, magnetite, and silica below 350 metres.
Surface sampling in the area had previously returned up to 1.14 per cent Cu and 5.73 g/t Au. Structural data suggest the potassic zone may project back to surface northeast of the drill trace, potentially indicating the centre of a porphyry system.
Next Steps: Soil sampling and geophysics
Yukon Metals plans to launch a series of surface programs in September to refine exploration vectors and prioritize future drill targets. This includes:
- Contour soil sampling analyzed by multi-element ICP-MS and hyperspectral methods.
- Ground-based IP surveys to detect chargeability and resistivity anomalies.
- High-resolution airborne magnetic surveys to differentiate magnetite sources and identify skarn systems.
- Hyperspectral and petrographic studies to refine mineralogical understanding.
About the AZ Project
Initial mapping and sampling in 2024 revealed a 1.2-kilometre zone of iron-stained and altered rocks on Chair Mountain, with consistent copper mineralization. Of 60 rock-chip samples, 18 returned copper values between 0.12 per cent and 3.49 per cent. The area is associated with a NW-trending fault zone and past gold production at Sanpete Creek.
The presence of hematite alteration, quartz veins, and clay-altered diorite dykes linked to the Nutzotin suite suggests a large hydrothermal system, potentially capable of hosting significant porphyry copper deposits.
