Cheechoo is Sirios's 100%-owned flagship gold project in Eeyou Istchee James Bay, covering approximately 119 km² in three non-contiguous blocks after recent claim abandonment. The deposit is approximately 15 km southeast of the Éléonore mine and has road and power infrastructure nearby. The current July 2025 NI 43-101 estimate contains pit-constrained Indicated and Inferred resources plus a higher-grade underground Inferred component. A fully permitted 25,000 m first-phase expansion program began in June 2026; Sirios plans an updated resource followed by a PEA in H1 2027.
