Montreal (Quebec) – Sirios Resources Inc. (TSX-V: SOI) has 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.

Cheechoo Property (300 claims, 157 km2)

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 (Figure 2), 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.

Pontax Property (70 claims, 37 km2)

The Pontax property is located along the northeast extension of the prolific Chambois greenstone belt (Figure 3). A major drilling program, targeting the lithium-rich pegmatites in this geological corridor is currently underway by Cygnus Gold (ASX: CY5) on its block of three optioned properties. Sirios’ Pontax property is directly adjacent to this block of properties, highlighting the excellent lithium exploration potential of our project.

Maskwa Property (395 claims[1], 202 km2)

In addition to the gold, tungsten and platinum group element (PGE) anomalies detected in 2020 by Sirios on the property following till surveys, the Maskwa property also has strong exploration potential for lithium, as demonstrated by the presence of several lithium anomalies as defined by regional lake-bottom sediment samples (Figure 4). Sirios recently acquired 23 additional claims, expanding the property to the east.

Li-52 Property (266 claims[2], 139 km2)

Following an in-depth evaluation of the lithium potential in the James Bay area, Sirios recently acquired 266 claims, developing the new Li-52 property (Figure 5). This property, located approximately 20 km south of the Maskwa property, has excellent lithium potential, as indicated by the presence of several lithium, cesium, rubidium and gallium anomalies in lake-bottom sediment samples.
