Harfang and SOQUEM Extend Mineralized Trends at Menarik West, Québec

Montreal, Quebec--(Newsfile Corp. - September 30, 2026) - Harfang Exploration Inc. (TSXV: HAR) (" Harfang ") and SOQUEM Inc. (" SOQUEM ", together the " Companies ") are pleased to announce the confirmation and extension of gold mineralization at the Adrian and Cox showings from the summer 2026 exploration program at Harfang's wholly owned Menarik West Property (the " Property ") in Eeyou Istchee James Bay, Québec (see Figures 1 and 2).

HIGHLIGHTS

Adrian discovery extended along a 200-metre long trend. Prospecting has extended the 2025 Adrian discovery (3.67 g/t Au) along an east-northeast trend over approximately 200 metres; new grab samples include: 7.13 g/t Au, 4.93 g/t Au, and 4.19 g/t Au (see Table 1).

First channel samples from Cox suggest a 250-metre long mineralized trend. Four of five channels intersected gold mineralization over a strike length of approximately 250 metres; assay highlights include: 0.88 g/t Au over 8.35 m (incl. 5.31 g/t Au over 0.91 m), and 0.99 g/t Au over 6.75 m (incl. 4.16 g/t Au over 1.00 m) (see Table 2).

Adrian and Cox both coincide with Induced Polarization chargeability anomalies. Both gold trends coincide with chargeability anomalies identified by the winter 2026 induced polarization (" IP ") survey.

Finalizing targets for the fully funded 2027 diamond drill campaign. Today's results are being integrated, along with the recently completed IP survey and geological interpretation, to finalize the drill targets for the joint Harfang-SOQUEM fully funded winter 2027 drilling program.

Rick Breger, President and CEO of Harfang, commented, " We are encouraged by the results from this summer's program, particularly the confirmation of gold mineralization at Cox through our first channel samples, and the extension of the Adrian trend to approximately 200 metres. Importantly, both trends coincide with strong geophysical signatures identified through our winter
