Update on Sirios’ Summer 2022 activities

Corporate Updates

TSX-V : SOI June 14, 2022

Update on Sirios’ Summer 2022 activities

Montreal (Quebec) – The management of Sirios Resources Inc. (TSX-V: SOI) is pleased to announce

an update on the work currently in progress on its two main projects, the Cheechoo and Aquilon gold

properties.

CHEECHOO:

The update of the Cheechoo geological model including the latest drilling results has been completed.

The mandate to update the mineral resource estimate will therefore soon be awarded to an engineering

firm.

A construction team is currently onsite at the Cheechoo camp to improve the camp infrastructure. These

upgrades will increase the accommodation capacity of the camp, thereby allowing to scale-up future

exploration and development activities.

Another construction team is also onsite to improve the Cheechoo access road, which will increase the

efficiency and speed of logistics for coming exploration and development programs.

Prospecting work will be carried out during the months of June and July 2022 in the area to the east of

the 2020 conceptual pit in order to extend the new gold zone which had been intersected in the meta-

sedimentary rocks during the summer 2021 drilling campaign (ref. press release of 14/12/2021 ). The

meta-sedimentary rocks surrounding the Cheechoo deposit remain a mostly unexplored geological unit to

date and will therefore be targeted as a priority this summer.

Finally, typical samples of the Cheechoo gold mineralization will be taken in order to carry out new

metallurgical tests in order to determine the optimal treatment process for the Cheechoo deposit.

AQUILON:

A team of geologists from Sirios is currently onsite on the Aquilon property in order to proceed with the

complete and standardized description (“relogging”) of Aquilon’s historic drill cores. The information

resulting from this relogging program will allow new modeling to be carried out based on the new

structural data collected in September 2021. This update of the geological modeling of the Aquilon

property represents one of the first stages of a systematic exploration program extending until 2024.

About the Cheechoo Property

The Cheechoo gold property is 100% owned by Sirios and consists of 225 claims covering an area of 118

km2, divided into three non-contiguous blocks. It is located in Eeyou Istchee James Bay, Quebec, less than

9 km from Newmont’s Eleonore gold mine and is easily accessible by road in all seasons. The project's

latest resource estimate (October 2020) delineated inferred resources of 2.0 million ounces of gold

contained in 93.0 million tonnes at 0.65 g/t Au , with significant potential to increase in this resource

(BBA, P-L. Richard, P. Geo.; J. Torrealba, P. Eng.; D. Evangelista, P. Eng., NI 43-101 Technical Report,

Mineral Resource Estimate Update for The Cheechoo Project, 31/10/2020).

About the Aquilon property

The Aquilon gold property is 100% owned by Sirios and consists of 140 claims covering an area of 68

km2. It is located in Eeyou Istchee James Bay, Quebec, 10 km south of the Laforge-1 hydroelectric power

station and is easily accessible by road in all seasons. To date, 32 gold showings have been discovered on

the property. Some drill intersections on the Aquilon project are among the highest grades obtained in

Quebec, including 12,906.5 g/t Au over 0.20 m (Lingo showing), 3,527.4 g/t Au over 0.40 m (Moman

showing) and 133.67 g/t Au over 0.82 m (Fleur-de-Lys showing) (ref. press releases of 26/06/2008 and

19/01/2011).

The scientific and technical content of this press release has been reviewed and approved by Roger Moar,

P.Geo. and Dominique Doucet, P.Eng., both qualified persons under National Instrument 43-101.

About Sirios

A pioneer in the discovery of significant gold deposits in Eeyou Istchee James Bay in Quebec, Canada,

Sirios Resources inc. is focused primarily on its Cheechoo gold discovery while actively exploring the

high gold potential of its other properties.
