SIRIOS VALIDATES PHOTONASSAY™ GOLD ANALYSIS TECHNOLOGY WITH SAMPLES FROM THE CHEECHOO GOLD DEPOSIT

Sirios Resources Inc.'s validation testing of the PhotonAssay gold assay technology has been successfully completed. As previously announced (reference: press release dated June 12, 2023), about 100 core samples from selected sections of previous drilling at the Cheechoo gold deposit were sent to MSALABS laboratories in Val d'Or in order to evaluate this new assay technique. Based on these results, core samples taken during the recent 2023 drilling campaign will be analyzed using this technology, which has among other things, a lower environmental impact than other commonly used analytical techniques.

Dominique Doucet, president of Sirios, commented: "We are very proud to be using this new technology which has just been introduced in Quebec. Since analyses will be performed on a standard quantity of approximately 500 grams of material, instead of the usual 50 grams used for fire assay, we believe it will be more appropriate for analyzing samples containing coarse free gold (resulting in the nugget effect). In addition, since PhotonAssay analysis is non-destructive, it will allow the sample to be used in the future for other tests, if required. Finally, the time required to receive our analytical results should be shorter."

About Cheechoo property

Sirios's 100-per-cent-owned Cheechoo property is in the Eeyou Istchee James Bay region of Quebec, approximately 800 km north of Montreal, 200 km east of Wemindji and less than 10 km from Newmont's Eleonore gold mine.

The last update of the mineral resource estimate for Cheechoo, based on an open pit constrained model, includes an indicated resource of 1.4 million ounces of gold contained in 46.3 million tonnes at an average grade of 0.94 g/t Au, and an inferred resource of 500,000 ounces of gold contained in 21.1 million tonnes at an average grade of 0.73 g/t Au with significant potential for increasing these resources (BBA, PLR Resources, P-L.
