LITHIUM: SIRIOS INCREASES THE SURFACE AREA OF ITS LI-52 PROPERTY IN EEYOU ISTCHEE JAMES BAY, QUEBEC

Sirios Resources Inc. has acquired, by map designation, 160 additional claims on its Li-52 property, located in Eeyou Istchee James Bay. The property is currently made up of 710 claims covering an area of over 369 square kilometres, Sirios's largest property. It has excellent potential for lithium, as indicated by the presence of several lithium, cesium, rubidium and gallium anomalies in lake-bottom sediment samples (see March 1, 2023, press release). The newly acquired claims consolidate the property to the north, northwest and west. Sirios now holds 1,821 claims (including 11 claims pending) in the Eeyou Istchee James Bay region, covering more than 939 square kilometres, which gives the company a very favourable position in relation to the prospective potential of the region for lithium.

The scientific and technical content of this press release has been reviewed and approved by Dominique Doucet, PEng, Jordi Turcotte, PGeo, and Guillaume Doucet, PGeo, all qualified persons under National Instrument 43-101.
