Sirios Resources Inc. (TSX-V: SOI) (OTCQB: SIREF) is pleased to announce the results from the two first drill holes of the Phase 1 of its Fall-Winter 2024-25 Drilling Program on the Cheechoo gold project in Eeyou Istchee James Bay, Québec.

The two drill holes intercepted gold mineralization exactly at the locations anticipated by Sirios’ geological team. These results help validate the new interpretation of the Cheechoo deposit, which reinforces the potential for high-grade zones, paving the way for possible development combining open-pit and underground mining.

Phase 1 of the Fall-Winter 2024-25 Drilling

Sirios has completed drilling of the 4 holes constituting phase 1 of the Fall-Winter 2024-25 program for a total of 1,882 meters. Core samples from holes #319 and 320 are currently being analyzed.

Strategic Objectives

The primary objectives of this drill program are to:

1. Gather data to support an upcoming Mineral Resource Estimate (MRE) update;
2. Test high-priority targets identified during the comprehensive data review conducted by Sirios during the summer of 2024.

Cheechoo’s High-Grade Zones

The Cheechoo gold deposit is hosted in a tonalite intrusion characterized by multiple gold-enriched zones encased in a lower-grade halo. In addition to the Eclipse zone. numerous high-grade intervals throughout the deposit suggest the occurrence of additional high-grade zones. These zones may be found both within and beyond the boundaries of the 2022 Mineral Resource Estimate (MRE) conceptual pit.

About the Cheechoo Property

Located less than 15 km from Newmont’s Éléonore gold mine in the Eeyou Istchee James Bay territory of Québec. the Cheechoo property. 100% owned by Sirios. contains an untapped gold deposit with excellent expansion and development potential.

The most recent mineral resource estimate (MRE) reported. for an open-pit model. using a USD 1.650 gold price:

• Indicated resources: 1.4 million ounces at an average grade of 0.94 g/t Au;
• Inferred resources: 500.000 ounces at an average grade of 0.73 g/t Au.
