Sirios Resources: Visible Gold Found at

Multiple Depths in First Drill Hole of Fall

2024 at Cheechoo

November 25, 2024

Montréal, QC – Sirios Resources Inc. (TSX-V: SOI; OTCQB: SIREF) (“Sirios” or the “Company”) is

pleased to announce the presence of visible gold at eight diƯerent locations in the first drill hole

of its Fall 2024 program on the Cheechoo gold project in Eeyou Istchee James Bay, Québec.

Multiple gold grains were observed by Sirio’s geologists in drill hole CH24-317 (Figure 1) at the

following depths:

 86.6m;

 91.7m;

 128.0m;

 167.5m;

 178.3m (Figure 2);

 189.0m (Figure 3);

 331.3m;

 Between 356.9m and 358.3m (Figure 4).

These observations confirm the presence of gold at multiple locations along the hole, but only

laboratory assay results will specify the gold grade. The drill hole was completed yesterday after

reaching the planned depth of 399 meters.

Ongoing Drilling Program

Sirios is currently carrying out the first phase of a diamond drilling program targeting high-grade

zones of the Cheechoo gold deposit. The Phase 1 program will consist of approximately 2,000

meters of drilling. Phase 2 will be of greater scope and will be carried out during the winter of 2025.

Phase 1 focuses on delineating and expanding high-grade zones in the eastern part of the deposit.

Phase 2 will expand drilling to the western part of the deposit, including the high-grade Eclipse

zone.

This drilling campaign marks a significant milestone in the Company's new vision for the project,

targeting high-grade zones with potential for both open-pit and underground development.

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 (see our interactive 3D model at

sirios.com/en/cheechoo). 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.

Underground mining scenarios have not been evaluated in the 2022 MRE.
