WALLBRIDGE LAUNCHES 2026 EXPLORATION AND TECHNICAL STUDIES PROGRAMS

Wallbridge Mining Company Ltd. has initiated its fully financed 2026 exploration and technical studies programs, highlighted by the commencement of drilling at its 100-per-cent-owned Fenelon gold project 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. The program is designed to advance Fenelon toward its next stage of technical development while continuing to unlock growth potential at the Martiniere gold project and earlier stage prospects along the company's 598-square-kilometre land position covering 82 kilometres of the prolific Detour-Fenelon gold trend.

"We are excited to have launched our fully funded, clearly defined 2026 exploration and development strategy. At Fenelon, our focus is on advancing the technical work required to further derisk the project and position it for the next stage of development. At the same time we are allocating capital to systematically evaluate the broader growth potential at Martiniere and across our regional property portfolio," commented Brian W. Penny, Wallbridge's chief executive officer.

"Our 2026 program is structured to balance longer-term development priorities with nearer-term resource growth opportunities, while maintaining financial discipline and flexibility as results are received," concluded Mr. Penny.

2026 exploration program overview

Fenelon

Drilling has commenced at Fenelon with one rig focused on targeted infill areas within the current mineral resource that forms part of the conceptual mine plan outlined in the company's March 27, 2025, preliminary economic assessment (PEA). This initial campaign will include approximately 2,000 metres of large-diameter (HQ) core drilling to support metallurgical testwork and related technical studies. The program is designed to further evaluate gold recoveries across the deposit and characterize residual tailings and waste rock material to further derisk the project as Wallbridge advances Fenelon along the development pathway to a future prefeasibility study.

The company has engaged Synectiq, an independent mining consultancy headquartered in Longueuil, Que., to oversee and co-ordinate the metallurgical testing and related technical studies included in the 2026 program. Synectiq brings extensive experience managing multidisciplinary engineering and development studies for mining projects and has supported the advancement of projects from PEA through prefeasibility and final feasibility stages.

Following completion of this campaign, a 1,500-metre reconnaissance drilling program is planned to test prospective targets located within approximately 2.5 kilometres of the main deposit area, in alignment the company's strategy of evaluating both near-deposit growth and regional upside.

Martiniere

In mid-March, a second drill rig will be mobilized to Martiniere where approximately 17,000 metres of drilling are planned in two phases. Phase 1 (mid-March to mid-May) will build on strong results from the 2025 exploration program and focus on expanding and evaluating the scale and continuity of the gold system. Phase 2 (early July to mid-September) will be designed based on phase 1 results, positioning Martiniere for potential future resource delineation as results warrant.

Casault and Grasset

Upon completion of the initial Fenelon campaign, drilling will move to the Casault property, where approximately 3,000 metres of reconnaissance drilling will test priority targets including the Vortex prospect and several untested structural intersections along the Sunday Lake deformation zone (SLDZ). The SLDZ is a key structural corridor along the Detour-Fenelon trend, which hosts Agnico Eagle's Detour Lake gold mine as well as Wallbridge's Fenelon and Martiniere projects. Wallbridge holds an option to earn a 50-per-cent interest in Casault through its agreement with Midland Exploration.

Following completion of Martiniere phase 2, approximately 1,500 metres of reconnaissance drilling are planned at the Grasset property to test newly identified targets along the eastern projection of the SLDZ.

The 2026 program will utilize two diamond drill core rigs from mid-February to mid-May, scaling down to one diamond drill rig from mid-May until the program's expected completion in late September.

Total expenditures for 2026, including corporate G&A (general and administrative), are anticipated to be approximately $27-million. This total includes a 30-per-cent increase in exploration and technical studies program costs compared to 2025. The company ended 2025 with a cash balance of $28.9-million.
