VISIBLE GOLD IN SIRIOS' FIRST DRILL HOLE OF 2024 AT ECLIPSE, CHEECHOO PROPERTY

Sirios Resources Inc. has noted the presence of visible gold in the first hole of the 2024 drilling program in the high-grade Eclipse area of its 100-per-cent-owned Cheechoo gold property.

The first hole of the program, CH24-305, intersected, at the targeted depth, multiple specks of coarse visible gold hosted in a chloritized quartz vein at 256.7 metres down the hole in a tonalite. Additionally, more than 100 grains of visible gold were encountered in a mafic dike at 258 m.

Over all, Sirios's geologists on site observed a 2.6-metre mineralized gold zone from 256.2 m to 258.8 m, including the gold-rich chloritized quartz vein, several deformed quartz veinlets with additional gold grains and the one-metre gold-bearing mafic dike. Arsenopyrite, pyrrhotite and scheelite were also observed throughout the zone.

About the drilling program currently under way at Eclipse

The high-grade Eclipse area, located west of the main area of the Cheechoo gold deposit, is not included in the updated 2022 mineral resource estimation (MRE), which outlined 1.4 million ounces of gold (indicated) and 500,000 ounces of gold (inferred) (BBA, mineral resource estimate update for the Cheechoo project, July 20, 2022).

Sirios is currently conducting a 1,000-metre diamond drilling program aimed at including Eclipse in the next update of the MRE for the Cheechoo property. Several high- and very-high-grade gold intervals were previously intersected in the Eclipse area.

A detailed presentation about the Eclipse high-grade gold area is available at the company's website.
