Yukon Metals Corp. (CSE: YMC) announced on October 14, 2026, that its 2026 drill program at the Viper Prospect has confirmed a new porphyry-style hydrothermal system hosting copper, gold, and molybdenum mineralization at its 100%-owned AZ Project, located 36 kilometres south of Beaver Creek, Yukon. All three drill holes intersected porphyry-style alteration and copper-gold-molybdenum mineralization, with copper values generally increasing with depth. The disclosure suggests the company views current drilling as having tested the upper levels or margins of the system, with the higher-grade core remaining an ongoing exploration objective. Investors in junior exploration companies with Yukon copper-gold assets may be watching this development closely.

Key Points

  • Yukon Metals Corp. (CSE: YMC, FSE: E770, OTCQB: YMMCF)
  • A copper-gold-molybdenum porphyry-style hydrothermal system confirmed at the Viper Prospect, AZ Project, Yukon
  • 1,948 metres drilled across three holes; peak intercepts include 1.85% copper and 1.97 g/t gold over 0.6 metres in hole AZ26-008, and 685 ppm molybdenum over 0.80 metres in hole AZ26-007
  • Investors may watch for results from pending assays in hole AZ26-007 and outcomes of ongoing petrographic and hyperspectral studies

Three-Hole Drill Program Validates Porphyry System at Viper

The 2026 program comprised three diamond drill holes totalling 1,948 metres, representing the first systematic drill test of the main Viper target. Copper values grading 0.20% or above were encountered at downhole depths ranging from approximately 429.3 to 736.8 metres. Porphyry-style alteration, including magnetite-actinolite-biotite with local K-feldspar, was identified in all three holes and is associated with disseminated and vein-hosted chalcopyrite and molybdenite. The company interprets this alteration pattern as consistent with other known porphyry systems globally, with calc-potassic alteration at depth and quartz-sericite-pyrite alteration observed both at surface and in drilling.

Grade Highlights and Depth Trends From AZ26-007 and AZ26-008

Selected intercepts reported in the announcement include 1.85% copper and 1.97 g/t gold over 0.6 metres in hole AZ26-008 at 633.3 metres depth, and 685 parts per million molybdenum over 0.80 metres in hole AZ26-007. The release notes that copper values generally increase toward the deeper portions of all three holes, which the company considers a meaningful vector for targeting the system's core. Results remain pending for a portion of hole AZ26-007 from 396.5 to 462.3 metres. All samples were analysed by SGS Canada Inc. in Burnaby, British Columbia, with quality control protocols confirmed as meeting acceptable thresholds.

East-Southeast Corridor Extends the Viper Target Beyond Current Drilling

Surface mapping, prospecting, and soil geochemistry have extended the prospective alteration and intrusive corridor east-southeast of the 2026 drill area. The release states this trend coincides with anomalous copper-gold-molybdenum pathfinder soil geochemistry, the dominant structural fabric, and a pronounced break in drone magnetic data. The company interprets the magnetic high as potentially reflecting magnetite enhancement from calc-potassic alteration, while the adjoining magnetic low may reflect magnetite destruction from later hydrothermal activity. Additional mineralogy, petrography, and whole-rock geochemistry work is underway and will be integrated with existing datasets to refine exploration targets.
