HARFANG PROVIDES WINTER EXPLORATION UPDATE

Harfang Exploration Inc. has concluded a highly productive winter exploration season across its portfolio of four wholly-owned projects in Quebec and Ontario, marking several significant operational milestones. The company successfully completed its maiden diamond drilling program at the Mista Cu-Au-Ag target on the Serpent project, totaling approximately 1,300 metres across six drill holes. Preliminary core logging has confirmed the presence of a mineralized system associated with a felsic intrusive body, with the first batch of assay results anticipated in mid-May 2026.

At Menarik West, conducted in partnership with SOQUEM, a 15-kilometre DC-IP survey has been completed and successfully identified high-confidence drill targets at both the Pierre intrusion and the newly discovered Cox zone. The Pierre intrusion data supports the interpretation that the mineralized system remains open at depth, building on previous drilling that intersected 1.15 g/t Au over 47 metres. At the Cox zone, where surface samples previously returned up to 19.2 g/t Au, the survey defined compelling drill targets supported by a strong chargeability corridor extending potentially more than 500 metres along strike.

The company's systematic approach to exploration is evident in its comprehensive data integration efforts. At Blakelock, the ongoing 60-kilometre DC-IP survey will be integrated into a 3D geological model to finalize drill targets for the 2027 program. This methodical approach to target generation positions Harfang well for future drilling campaigns with higher probability of success.

The winter program results demonstrate Harfang's ability to execute complex multi-project exploration campaigns while maintaining strong partnerships and community relationships. The company's engagement with the Mishkeegogamang Ojibway Nation regarding the Traditional Knowledge and Land Use Study at Sky Lake reflects industry best practices in Indigenous consultation. With multiple drill-ready targets now defined and fully funded drilling programs planned for 2027, Harfang has built substantial momentum heading into the next phase of exploration across its portfolio.
