- 04 Assay results
Assays from 15 holes totalling 6,850 m included 39.94 g/t Au over 6.5 m, including 129.00 g/t Au over 2.0 m, in CH26-337, and 9.07 g/t Au over 12.5 m, including 103.11 g/t Au over 1.0 m, in CH26-345. CH26-337 also returned 25.21 g/t Au over 3.0 m, including 50.06 g/t Au over 1.5 m, and CH26-334 returned 122.1 m at 0.43 g/t Au. Lengths are measured along the drill holes and true thickness was unknown. Phase 1 finished on September 28 at 45 holes and 23,037.5 m. Phase 2 of approximately 12,000 m is scheduled for January 2027, and the company said nearly half of the summer-campaign results had been received.

Sirios outlined a two-phase Cheechoo campaign of 35,000 m. Phase 1, about 25,000 m, was planned to start in the second quarter of 2026. A second phase of at least 10,000 m was planned for the first quarter of 2027.

About the project
Cheechoo is a reduced-intrusion-related gold deposit in Eeyou Istchee James Bay, about 15 km from the Éléonore mine. Phase 1 tested the exploration target inside the tonalite, metasediments along the northeast contact, and the Eclipse area west of the conceptual pit, and was completed on September 28, 2026. Phase 2, approximately 12,000 m, is scheduled for January 2027.
