Sirios resumes exploration on Aquilon, Eeyou Istchee James Bay region, Quebec

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

resuming exploration work in the Eeyou Istchee James Bay region. The Sirios exploration team is

currently pursuing work on the Aquilon gold property in partnership with Sumitomo Metal Mining Canada

Ltd. (Sumitomo). Mapping and rock sampling on a series of trenches; a property -wide soil geochemical

survey; a structural study; and borehole and drone geophysical surveys will be undertaken in the coming

weeks.

An airborne LiDAR survey was completed last June over the entire property (67.4 km2). This survey is in

addition to large-scale geochemical till sampling, approximately 40-line km of Induced Polarization (IP)

ground geophysical survey, and twelve mechanically excavated trenches completed last March.

The current exploration program is financed by Sumitomo, with Sirios as operator. Sumitomo has the

option to earn an 80% interest in the Aquilon project by making an investment of $14.8 million (ref. press

release of 12/19/2022).

One-year extension to the validity of mining claims in regions affected by forest fires

Management of Sirios wishes to express its great appreciation for the exceptional measure recently

undertaken by the Quebec Ministry of Natural Resources and Forestry, which adds 12 months to the

current expiry date of an eligible claim. Eligible claims are mainly those acquired before January 1, 2022

and located in territories affected by extended forest access and circulation bans due to forest fires (ref.:

https://mrnf.gouv.qc.ca/en/mines/mining-rights/directives-notices/notices-2023/). This measure affects

876 claims held by Sirios covering 451 km2 in Eeyou Istchee Baie James.
