Yukon Metals Confirms New Copper-Gold-Molybdenum Porphyry-Style System at Viper Prospect

VANCOUVER, British Columbia, Oct. 14, 2026 /CourierPR/ -- Yukon Metals Corp. (CSE: YMC, FSE: E770, OTCQB: YMMCF) has announced the discovery of a new copper-gold-molybdenum porphyry-style system at the Viper Prospect, part of its 100%-owned AZ Project, located 36 kilometres south of Beaver Creek, Yukon. The 2026 exploration program, which included diamond drilling combined with drone magnetics, ground induced polarization (IP), regional geological mapping, prospecting, and geochemical sampling, has confirmed the presence of this mineralized system.

The exploration program, conducted over a total of 1,948 metres across three holes, has intersected copper-gold-molybdenum mineralization. Copper values generally increased with depth, with samples grading 0.20% copper encountered at downhole depths ranging from approximately 429.3 to 736.8 metres. Notably, Hole AZ26-008 returned up to 1.85% copper and 1.97 grams per tonne (g/t) gold over 0.6 metres, while Hole AZ26-007 showed 685 parts per million molybdenum over 0.80 metres.

The alteration pattern at Viper is consistent with other porphyry systems, featuring quartz-sericite-pyrite (QSP) alteration both at surface and in drilling, and magnetite-actinolite-biotite ± K-feldspar alteration at depth. The Company interprets this as evidence of a porphyry system, with the drilling likely testing upper levels or margins rather than the centre. Anomalous soil samples, a pronounced magnetics trend, and an IP chargeability high extend the target corridor east-southeast beyond current drilling.

The 2026 drill program was the first systematic test of the main Viper target area, building on exploration conducted in 2025. That year, soil sampling outlined anomalous copper-molybdenum-gold ± silver values, now part of the Viper Prospect. A 1.8-kilometre IP line identified coincident chargeability highs and resistivity lows beneath the soil anomaly, defining clear drill targets. The 2026 holes tested these targets and provided the first subsurface information across the interpreted intrusive and structural corridor.

Drilling at Viper intersected vein and disseminated copper-gold-molybdenum mineralization within a multi-phase diorite-gabbro intrusive complex. Mineralization is associated with calc-potassic alteration, comprising magnetite, actinolite, biotite, and K-feldspar, variably overprinted by chlorite-sericite alteration. Copper values increase toward the deeper portions of each of the three 2026 drill holes. These downhole trends, together with changes in alteration and intrusive character, will be integrated with the surface geochemical and geophysical datasets to refine follow-up targets.

Additional mineralogy work, petrography, and whole rock geochemistry are underway and will be integrated with the geological, geochemical, and geophysical datasets to further refine follow-up targets. The Company's next objective is to vector toward Viper's potentially higher-grade core.

The Viper Prospect has developed into a strong copper-gold-molybdenum porphyry target at Yukon Metals' flagship AZ property. All three holes drilled this year encountered hundreds of metres of porphyry-style alteration with locally developed copper-gold-molybdenum mineralization. With QSP alteration at surface, converging magnetic trends, and a coincident IP chargeability high, these results define clear targets for the next round of drilling.
