The Douay deposit is situated within the northern Abitibi Greenstone Belt, a world-class Archean gold district. Gold mineralization at Douay is primarily hosted in a bimodal volcanic and intrusive sequence, dominated by syenitic intrusions and basaltic flows, crosscut by major deformation structures associated with the Casa Berardi Deformation Zone.

• Nika Zone: Syenite-hosted, broad, high-grade intercepts at depth; site of the 2025 step-out success (2.05 g/t Au over 108.6 m).
• Porphyry Zones (West, Central, East): Structurally-controlled, lower-grade, high-tonnage gold system comprising over 55% of current contained ounces.
• Central & NW Zones: Emerging areas of interest with higher-grade intersections and limited historical drilling.

Mineralization remains open laterally and at depth across all major zones, with particular emphasis now on bulk-tonnage underground targets beneath and beyond the current pit shells.Mineralization occurs as broad zones of disseminated and fracture-controlled gold within variably fenite-altered syenite, hydrothermal breccias, and intercalated volcanic rocks. Alteration assemblages include K-feldspar, amphibole, magnetite, quartz-carbonate, and chlorite, with 5–15% disseminated pyrite locally associated with elevated gold grades.
