Wesdome confirms new parallel zone at Kiena Deep, extends Eagle River mineralization

A new 150-metre vertical mineralized corridor in Kiena Deep confirmed via N134-7152W1: 6.9 g/t Au uncapped over 42.1 m core length. This Norbenite Footwall area is open in all directions and represents a potential new mineralized corridor accessible from existing development levels. High-grade results extend multiple Kiena Deep zones, highlighted by 124.1 g/t Au uncapped over 2.5 metres core length (64.5 g/t Au capped, 0.7 m true width) in the A2 223 lens, confirming the high-grade Kiena Deep system continues to grow.

Extended Eagle River's 800 Zone another 300 metres below the existing mineralization wireframe, confirming the continuation of high-grade gold mineralization in a deformation corridor broader than previously understood, with the zone remaining open down-plunge and along strike. Intersected 618.2 g/t Au over 0.5 metres core length (200 g/t Au capped, 0.35 metres true width), approximately 70 metres to the east and outside of the high-grade domain within the 300 Zone at Eagle River. This intercept represents initial results of exploration and conversion drilling on global model target #19 and highlights potential for further higher-grade intercepts.

Broad continuous step-out intercepts at Mishi support potential open pit at Eagle River, with down-plunge continuity indicating possible underground resource extensions at depth. Deeper drilling at the Cameron Lake Iron Formation at Eagle River continues to return broad gold intervals, confirming the zone remains open at depth and along strike and advancing the target as a longer-term mineable bulk-tonnage opportunity.
