Firefox Gold begins drill program at Mustajarvi

Executive Summary

• Firefox Gold Corp. has commenced an aggressive multi‑year exploration campaign at its 100 % owned Mustajarvi gold project in northern Finland, targeting >10,000 m of diamond drilling through spring 2026.
• The program includes simultaneous bottom‑of‑till (BoT) sampling on new distal targets (Mustajarvi West, East and Pikkulehto) beginning early September, with results expected to guide further drill testing.
• Management states the company is fully funded for the planned drilling and aims to deliver a maiden mineral resource estimate by mid‑2026 while also maintaining exploration activity at other projects (Sarvi and Jeesio).

Key Details

• Drilling Scope: >10,000 m of diamond core drilling slated between now and spring 2026 along the Mustajarvi shear zone.
• Target Areas: Infill and step‑out holes on existing mineralized zones (Central, Northeast, East) plus new targets proximal and distal to the main structures.
• First Hole: Collared ~280 m SW of the East zone centre, directed at an electromagnetic anomaly identified by a 2025 electrical geophysics survey.
• Historical Drilling: To date ≈15,752 m drilled, delineating three lodes over >1.5 km strike; most recent focus on near‑surface high‑grade mineralization in the East zone.
• Bottom‑of‑Till (BoT) Program: Commences early September; sampling across Mustajarvi West, East and Pikkulehto to develop drill targets where glacial cover obscures bedrock. Campaign runs through fall into early winter.
• Funding: Company confirms it is “fully funded” for the >10,000 m drilling program. No specific capital raise disclosed in this release.
• Future Milestones: Aim to issue a maiden mineral resource estimate by June 2026; additional updates on other portfolio properties (Sarvi, Jeesio) expected in September 2026.
• Qualified Person: Patrick Highsmith, CPG (AIPG No. 11702), director of Firefox Gold, reviewed and approved the technical information per NI 43‑101.
