Sirios Resources Inc. completed an in-depth evaluation for the lithium potential on its numerous properties located in Eeyou Istchee James Bay, Quebec. Sirios currently holds 1,447 claims in the James Bay region, totaling nearly 750 km2, which gives the company a very favorable position in relation to the lithium potential of the region (Figure 1). Four of Sirios' projects have been identified as very promising for hosting lithium due to their geological characteristics, their proximity to known lithium-bearing showings and the presence of regional geochemical lake-bottom sediment anomalies.

To date, Sirios' properties have never been explored specifically for lithium. Mineral prospects favorable to the presence of lithium mineralization have been identified on the Cheechoo property. The Pontax property is located less than one kilometre from and directly along the extension of the Stria Lithium and Cygnus Gold lithium-bearing pegmatite swarm, which is currently the subject of a major drilling program.

Significant geochemical lithium anomalies have been identified on the Maskwa property. The Li-52 property is a recently staked Sirios project, primarily targeting lithium based on highlighted lithium-rich lake-bottom sediment anomalies. Sirios has identified several lithium-rich spodumene-bearing boulders near numerous pegmatite outcrops, in the central part of the property, approximately 3 km north of the Cheechoo gold deposit.

Sirios has since acquired by map designation, 75 new claims up-ice of the boulders for their lithium exploration potential, thus expanding the property to the northeast. A detailed exploration program focusing on the lithium potential will be carried out in the area of the Cheechoo spodumene boulders starting in the summer of 2023.
