Sirios begins summer exploration program on Aquilon, Eeyou Istchee James Bay region, Quebec

Montreal (Quebec) – Management of Sirios Resources Inc. (TSX-V: SOI) is pleased to announce the start of the summer exploration program on its Aquilon gold property in the Eeyou Istchee James Bay region, in partnership with Sumitomo Metal Mining Canada Ltd. (Sumitomo). A soil geochemical survey (B horizon) will be initiated this week as a follow-up on the gold anomalous areas delineated during the property-wide soils geochemical survey completed in 2023. Some of the anomalous areas lie outside of the known gold mineralization and are hence considered as new prospective exploration targets. The in-fill soils geochemical survey will consist of approximately 1,000 samples collected every 50 m over sampling lines spaced at 100 m interval.

In addition, a series of mechanical strippings will be carried out over selected targets based on their geochemical signature but also evaluated from the re-interpretation of structural and geological context recently completed by the exploration team. A geological mapping and channel sampling program will be carried out during fall 2024 over all the strippings.

This exploration program is designed to generate targets to a drill-ready stage by the beginning of 2025.

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).
