Visible Gold Observed in Extension of Drill Hole #317 at Cheechoo

Montreal, QC – Sirios Resources Inc. (TSX-V: SOI; OTCQB: SIREF) (“Sirios” or the “Company”) is pleased to announce the presence of visible gold in the extension of drill hole #317 drilled this week on the Cheechoo gold project in Eeyou Istchee James Bay, Quebec.

Several gold grains were observed yesterday by Sirios geologists in quartz veinlets at depths ranging from 499.5 to 507.5 m along the hole. The 2025 drilling began this week by drilling the planned 100 m extension to this hole, initially completed at a depth of 397.8 m last December. Following these observations, the hole was extended to 522 m.

These observations confirm the presence of gold in the drilled extension, but only laboratory analysis results will specify the gold grade and its extent. Phase 2 of the 2024-2025 drilling program continues at Cheechoo.

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.

Qualified Person Statement and NI 43-101 Disclosure

The Mineral Resource Estimate mentioned in this press release conforms to National Instrument 43-101 standards and was prepared by Pierre-Luc Richard. P. Geo., independent qualified person, as defined by NI 43-101 guidelines. The effective date of the estimate is July 20, 2022. The above-mentioned mineral resources are not mineral reserves as they do not have demonstrated economic viability. The quantity and grade of the reported Inferred Mineral Resources are conceptual in nature and are estimated based on limited geological evidence and sampling. Geological evidence is sufficient to imply but not verify geological and grade or quality continuity.

Analytical quality control

The drill core was described and sampled by Sirios staff at the Cheechoo exploration camp. The core was sawn into two halves, one sent to a certified commercial laboratory for analysis, and the other retained for future reference. Following a strict analytical quality assurance and control program, blanks and certified reference materials were integrated into the sampling sequence. Samples were assayed for gold, on approximately 500g of crushed material, with the Photon AssayTM method (PAAU02) at the MSALABS laboratory located in Val-d’Or. Samples with the presence of visible gold were assayed using the entire sample material with the Photon AssayTM method. A whole-rock geochemical analysis was also performed by ICP-MS and ICP-OES on most of the samples.

The scientific and technical information contained in this press release has been reviewed and approved by Dominique Doucet P. Eng., who is a Qualified Person as defined by National Instrument 43-101.
