SIRIOS INITIATES DRILLING IN CHEECHOO'S HIGH-GRADE ECLIPSE GOLD AREA

Sirios Resources Inc. has started 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, 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).

Highlights:

• Previous drilling defined the high-grade Eclipse zone over approximately 120 metres laterally, two to six 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.
• 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 per cent) as well as visible gold grains.

Dominique Doucet, president and chief executive officer 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 the company at booth No. 2910.

The scientific and technical content of this press release has been reviewed and approved by Mr. Doucet, PEng, president and CEO of Sirios Resources, and Jordi Turcotte, PGeo, qualified persons under National Instrument 43-101.
