Yukon Metals Expands Porphyry Portfolio With New Northern BC Property Near Yukon Border

Press Release

VANCOUVER, British Columbia, May 12, 2026  — Yukon Metals Corp. (CSE: YMC, FSE: E770, OTCQB: YMMCF) (“Yukon Metals” or the “Company”) is pleased to announce that it has acquired a 100% interest in the KLM Property (the “Property”), located in northern British Columbia near the Yukon border. The Property comprises 8 mineral claim groups covering approximately 11,761 hectares and is situated within a prospective region characterized by extensive intrusive rocks and favourable structural architecture considered conducive to porphyry-style mineralization. The Property was originally staked on behalf of the Company pursuant to a grubstake arrangement between the Company and an arm’s length third party and subsequently transferred to the Company.

“Yukon Metals has identified a prospective copper porphyry corridor extending from northern British Columbia into the Yukon, and we have systematically built a land position across it,” said Jim Coates, Chief Executive Officer and a Director of Yukon Metals. “We are pleased with the addition of the Property as our copper-gold portfolio now includes four properties, Birch, Sumo, AZ, and KLM.

Historical work in the area has identified mineral occurrences within and adjacent to the Property associated with a granitic intrusive complex, suggesting the presence of a mineralized hydrothermal system. Initial review further indicates geological features consistent with porphyry-style mineralization, including quartz veining with associated molybdenum-copper ± lead-zinc mineralization. Exploration on the Property to date has been limited, and the Company plans to complete a compilation of available data followed by initial reconnaissance work, including geological mapping and sampling, to further evaluate its potential.

The Property aligns with the Company’s copper porphyry belt targeting approach and complements its ongoing exploration activities in the region. The Company’s current exploration programs remain focused on the AZ and Birch copper-gold porphyry-skarn projects, while KLM represents an early-stage addition to the copper-gold portfolio.

The Yukon

The Yukon Territory is an underexplored and minerally endowed district with a mining history dating back to the Klondike Gold Rush of 1898. With a progressive permitting regime, geopolitical stability and supportive government, it is well positioned to foster the next generation of mines. The Yukon is host to a highly experienced and conscientious local workforce, fostered by a long culture of exploration coupled with deep respect for the land. Recent major discoveries with local roots such as Snowline Gold Corp.’s Rogue Project – Valley Discovery, demonstrate the Yukon’s potential to generate fresh district-scale mining opportunities.
