Sirios Initiates Drilling in Cheechoo's High-Grade Eclipse Gold Area

MONTREAL, Feb. 13, 2024 - Management of Sirios Resources Inc. (TSX-V: SOI; OTCQB: SIREF) are pleased to announce the start of a 1,000-metre diamond drilling program aimed at including the high-grade Eclipse area in the next update of the Mineral Resource Estimation (MRE) for the Cheechoo property.

Located west of the main Cheechoo gold deposit (figure 1), the Eclipse area is not included in the updated 2022 MRE, which outlined 1.4 Million Gold Ounces (Indicated) and 500,000 Gold Ounces (Inferred) (BBA, Mineral Resource Estimate Update for the Cheechoo Project, 20/07/2022).

Highlights:

• Previous drilling defined the high-grade Eclipse zone over approximately 120 m laterally, 2 to 6 metres in width and over 250 m deep (open at depth).
  
• Several high- and very high-grade gold intervals were intersected in the Eclipse area (figure 2).
  
• Gold mineralization at Eclipse is associated with various quartz-feldspar veins, veinlets and stockworks hosted in a tonalite intrusion, with the presence of arsenopyrite and pyrrhotite (typically 0.5 to 1%) as well as visible gold grains.

Dominique Doucet, President and CEO of Sirios, stated: "Due to the high-grade gold content of the Eclipse zone, we can foresee an underground mining scenario using a ramp access for this zone that would enable us to reach the mining operation stage more quickly. This underground operation would then set the stage for starting large-scale open-pit mining in the main area of the Cheechoo deposit."

Upcoming Event
Sirios will be attending the 2024 PDAC Convention in Toronto from March 3 to 6. Come and meet us at booth #2910!
