Sirios Resources Kicks Off Phase 1 Drill

Program At Cheechoo Gold Project

November 19, 2024

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

pleased to announce the commencement of its Phase 1 drill program at the Cheechoo gold

project, located in Québec's Eeyou Istchee James Bay territory. 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.

The Phase 1 program will consist of 2,000 to 3,000 meters of diamond drilling. Phase 2 will be of

greater scope and will be carried out during the winter of 2025.

Phase 1 will focus on delineating and expanding high-grade zones in the eastern part of the

Cheechoo gold deposit (figure 1). Phase 2 will expand drilling to the western part of the deposit,

including the high-grade Eclipse zone.

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 (see Table 1).

Analytical Protocols and Data Verification Procedures

Each sample in Sirios' Cheechoo database has undergone gold assaying at a certified laboratory and

been subjected to comprehensive quality assurance and quality control (QA/QC) procedures. These

procedures include the use of certified reference materials (CRMs), field and laboratory duplicates,

blank materials, and external laboratory checks. As assaying methods have evolved over time,

detailed information about the specific protocols used for each drill hole is available in the past press

releases on Sirios' website at www.sirios.com.
