WALLBRIDGE MINING ANNOUNCES DRILLING HAS COMMENCED AT MARTINIERE

Wallbridge Mining Company Ltd. has commenced drilling at its Martiniere gold project, located within the Wallbridge land package in northwestern Quebec.

The 2026 program represents one of the company's more active exploration seasons in recent years, with approximately 25,000 metres of drilling planned across the Fenelon, Martiniere, Casault and Grasset properties; 17,000 metres of that drilling are taking place at Martiniere planned in two phases. Phase 1 has commenced, which is building on strong results from the 2025 exploration program and is focused on continuing to expand and evaluate the scale and continuity of the broader gold system as it extends beyond the limits of the currently reported mineral resource. Phase 2 (planned to start in early July and conclude in September) will be designed based on phase 1 results, positioning Martiniere for potential future resource delineation as results warrant.

"We believe continued exploration at Martiniere offers significant potential to unlock additional value for shareholders as we advance our assessment of the property's district-scale growth opportunities while targeting near-term resource expansion," commented Brian Penny, Wallbridge's chief executive officer. "At the same time, we remain focused on advancing the technical work required to further derisk Fenelon and position the project for its next stage of development," concluded Mr. Penny.
