SIRIOS EXTENDS THE ECLIPSE ZONE 400 METRES DOWNDIP AND IT REMAINS COMPLETELY OPEN

Sirios Resources Inc. has released the final analytical results from the 3,200-metre winter 2024 drilling program in the Eclipse area of the Cheechoo gold project located in Eeyou Istchee James Bay, Quebec. The drill program successfully confirmed the continuity of the Eclipse Zone, significantly extended the zone at depth and intersected gold in new areas outside the main Eclipse Zone.

Drill Result Highlights:

• 105.21 g/t Au over 0.8 m, included in 14.16 g/t Au over 6.4 m (CH24-305)
• 24.42 g/t Au over 1.0 m, included in 3.89 g/t Au over 7.0 m (CH24-306)
• 12.82 g/t Au over 0.8 m (CH24-311)*
• 28.47 g/t Au over 1.0 m (CH24-313)*
• 10.64 g/t Au over 1.5 m (CH24-314)*
• 4.05 g/t Au over 3.8 m (CH24-314)
• 47.65 g/t Au over 0.9 m, included in 4.48 g/t Au over 10.5 m (CH24-316)
• *Outside the main Eclipse Zone

All drill holes intersected the Eclipse Zone, confirming its excellent continuity (Figure 1). The program extended the mineralized zone to more than 400 meters downdip to the north and nearly 120 meters laterally (Figure 2). The winter 2024 drilling program also intersected several high-grade gold intervals outside of the main Eclipse Zone, which suggests the possible presence of other high-grade subparallel zones ("stacked zones").

"We are very pleased with the results obtained in this drill campaign. The high-grade nature of the Eclipse Zone, its excellent continuity, its dip angle and the fact that mineralization begins at surface are all favorable characteristics for potential underground mining development. Sirios will therefore be able to assess the mining potential of this zone for development using a ramp," commented Dominique Doucet, CEO of Sirios.

About the Eclipse Area

A large volume resource of 1.4 million ounces of gold (Indicated) and 500,000 ounces of gold (Inferred) has already been delineated in the main area of the Cheechoo deposit (Figure 3). The Eclipse area includes a high-grade gold zone that has not been included in the current resource. For more information, see the Eclipse Area Presentation. About the Cheechoo Property

The Cheechoo Gold property, 100% owned by Sirios, is located in Eeyou Istchee James Bay, Quebec, 200 km east of Wemindji and less than 10 km from Newmont's Eleonore gold mine. The property's latest resource update delineated, for an open pit model, Indicated Resources of 1.4 million ounces of gold contained in 46.3 million tonnes at an average grade of 0.94 g/t Au, as well as Inferred Resources of 500,000 ounces of gold contained in 21.1 million tonnes at a grade of 0.73 g/t Au (ref.: press release of 06/12/2022).

About Sirios

Sirios Resources is a Quebec-based mineral exploration company focused on developing its portfolio of high-potential gold properties in Eeyou Istchee James Bay, Canada.

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 Assay(TM) 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 Assay(TM) method.
