The project is located within the Company’s 100%-owned Rice Lake property in southeastern Manitoba, Canada, approximately 45 km southeast of its fully permitted True North mine and beneficiation plant complex (the “True North Complex”).
Highlights:
The 2026 underground mineral resource estimate for the Ogama-Rockland Project is reported based on stopes designed using the Deswik “Mineable Shape Optimizer” (“MSO”), applying a proposed economic cut-off grade of 2.5 grams of gold (“Au”) per mt:
Inferred mineral resources of 3,314,000 mt at an average gold grade of 6.68 g/mt, containing 712,000 ounces of gold
The 2026 Mineral Estimate identified potential areas for resource growth through additional drilling.
The modeled veins have expansion potential both down-dip and along strike.
Gap areas within the current resource envelope may increase resources.
The Company plans to conduct additional drilling in Q4 2026 to test the identified potential resource expansion areas.
