SOI Sirios Resources Inc

Sirios Resources Inc. (TSX-V: SOI; OTCQB: SIREF) (“Sirios” or the “Company”) is pleased to unveil a new vision for its Cheechoo gold project, located in Québec’s Eeyou Istchee James Bay territory. In the wake of the winter 2024 drilling program, Sirios embarked on a comprehensive management review of data, spanning several months. This in-depth analysis, conducted in collaboration with specialized geological and mining consultancy firms, including PLR Resources Inc., has yielded very promising results. The thorough examination has led to the identification of multiple high-priority targets for delineating high-grade zones that may lead to both open-pit and underground mining. Notably, the near-surface Eclipse zone has emerged as a standout prospect, exhibiting remarkable high-grade continuity across numerous drill holes (Figures 1 to 3). This strategic assessment has not only validated the company's exploration efforts but also opened up new avenues for future development at the Cheechoo gold project.

Dominique Doucet, CEO of Sirios, comments: “We are thrilled to launch this new vision for the Project. Cheechoo now presents dual potential: large-volume open-pit mining and/or high-grade underground development. This new outlook is a game changer for the Project, consequently leading our team to design an intensive drilling program targeting high-grade enriched zones.”

Cheechoo’s High-Grade Zones

The Cheechoo tonalite intrusion forms the centerpiece of the property, 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 (see Table 1).

Planned Drilling Program

Sirios' technical team is currently designing an intensive drilling program aimed at delineating high-grade zones within the property. The company intends to disclose comprehensive details about this strategic program in forthcoming press releases, offering stakeholders valuable insights into Sirios' exploration plans and objectives.

Mineral Resource Estimate (MRE) Update

Following this drilling program, Sirios will proceed with an update of the mineral resource estimate. This update will serve as the basis for a future Preliminary Economic Assessment (PEA).

New Website

We are also proud to announce the launch of our redesigned and updated website. We invite you to visit sirios.com to discover our revamped platform which offers an enhanced user experience, featuring our exclusive interactive 3D model viewer for the Cheechoo deposit.

A French version of the website will be available soon.

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 AuSource: BBA, Mineral Resource Estimate Update for the Cheechoo Project, 23/12/2022

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

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.
