WALLBRIDGE COMMENCES PHASE 2 DRILLING AT MARTINIERE

Wallbridge Mining Company Ltd. has commenced its second phase of drilling at its fully owned Martiniere gold project. The phase 2 campaign has been designed to follow up on the positive results returned from its phase 1 drilling campaign completed in May, 20205 (see Wallbridge's news releases dated June 2, 2025, and July 2, 2025).

The company is continuing to explore the broader mineralized gold system at Martiniere. Exploration is currently focused along the northwest-southeast-trending Bug Lake deformation corridor and satellite targets located within 100 to 500 metres of the Martiniere mineral resource (see Wallbridge's news release dated March 27, 2025). During phase 2, drilling will target potential extensions to high-grade gold mineralization along the Dragonfly, Horsefly and Martiniere North zones as well as the newly identified Martiniere Northeast target, where drill hole MR-25-115 returned 6.0 metres grading 3.84 grams per tonne gold (previously reported).

During the first and second quarters of 2025, the company's phase 1 campaign comprised 18 holes totalling 7,225 metres at Martiniere. Wallbridge plans to complete a total of 12,000 to 15,000 metres of drilling during 2025.

Additionally, generative reconnaissance fieldwork has commenced to identify earlier-stage greenfield exploration targets along the Detour-Fenelon gold trend. During 2025, greenfield exploration will focus on the Casault, Doigt, Martiniere, Fenelon and Grasset claim blocks, which comprise much of the company's 830-square-kilometre regional property position.
