Hole TOM-25-009 (from 244.50 m): 5.44% ZnEq (1.27 g/t AuEq) over 15.20 metres , including 25.15% ZnEq (5.85 g/t AuEq) over 2.55 metres. Hole TOM-25-010 (from 130.70 m): 2.67% ZnEq (0.62 g/t AuEq) over 48.30 metres , including 12.87% ZnEq (3.00 g/t AuEq) over 6.25 metres. Assay results are pending for five drill holes targeting the lateral and depth extensions of the known mineralized envelope (TOM-25-011 to TOM-25-015). Hydrothermal footprint : Identification of a significant hydrothermal signature at the roof of the main mineralization, providing valuable exploration guidance for potential extensions. Exploration ongoing : A Borehole EM survey is currently underway on the ground to identify new targets. TOMAGOLD CORPORATION (TSXV: LOT; OTCPK: TOGOF) (“ TomaGold ” or the “ Company ”) is very pleased to announce the initial assay results from drill holes TOM-25-009 and TOM-25-010 at its Berrigan Mine project located in the Chibougamau mining camp, in Québec. These are the first two of seven holes for a total of 3,098 metres at Berrigan Mine, with the objective of testing the historical mineralized structure and opening new potential mineralization at depth. The results confirm the presence of high-grade gold-bearing polymetallic vein systems within an extensive mineralized envelope hosted in ultramafic rocks. This press release features multimedia.

The confirmation of a hydrothermal footprint overlying the main mineralized zones significantly reinforces our geological understanding of the Berrigan Mine project. With the EM survey currently underway and extension drilling results expected in January, we look forward to defining the full scale and continuity of the mineralized envelope.” Jean Lafleur, P.Geo., VP Exploration at TomaGold, added: “TomaGold is currently advancing an all-encompassing litho-structural and geophysical compilation, synthesis and interpretation for its Chibougamau mining camp projects, incorporating AI modeling with Windfall Geotek’s proprietary system. We've also completed additional geophysical work to refine both gold and polymetallic targeting for the upcoming winter 2026 exploration campaign. This approach has already yielded new targets, which are currently being tested through diamond drilling. The latest drilling results at Berrigan Mine offer a glimpse into the exploration potential of some of these targets.” Mineralization at Berrigan Mine is primarily associated with carbonatized ultramafic rocks. Analysis of visually non-mineralized samples, including intervals initially excluded from sampling, has identified low-grade halos associated with quartz-carbonate stockwork that increase the potential volume of the mineralized envelope. A borehole EM survey is currently being conducted on holes from this campaign to guide future deep drilling. To ensure a comprehensive understanding of the system, the team proactively analyzed previously unsampled sections to ensure that no low-grade mineralization or alteration halos were overlooked. Next steps will include receipt of assay results in January 2026 for five additional holes testing lateral and depth extensions, integration of EM and complete core assay data into the resource model, compilation and characterization of alteration systems, and planning of a field exploration program. Phase 2 drilling will be planned following compilation of Phase 1
