Wallbridge Mining Announces Drilling Has Commenced at Martiniere

Toronto, Ontario – March 16 , 2026 – Wallbridge Mining Company Limited (TSX: WM,

OTCQB:WLBMF) (“Wallbridge” or the “ Company”) is pleased to announce that it has commenced

drilling at its Martiniere gold project (“ Martiniere”) 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 is 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 CEO. “ At the same

time, we remain focused on advancing the technical work required to further de -risk Fenelon and

position the project for its next stage of development,” concluded Mr. Penny.

Qualified Person

The Qualified Person responsible for the technical content of this news release is Mr. Mark A. Petersen

M.Sc., P.Geo. (OGQ AS-10796; PGO 3069), Senior Exploration Consultant for Wallbridge.
