Montreal (Quebec) – The directors of Sirios Resources inc. (TSX-V: SOI) are pleased to announce that lithium-targeted follow-up work will be performed on significant tantalum anomalies previously detected in till samples from the Maskwa property (press release July 5, 2023). The mandate for the work was awarded to IOS Services Géoscientiques inc. of Saguenay, Quebec (IOS) which will collect more than 110 till samples along sampling lines (WNW-ESE) over two target areas.


The planned work will test the Maskwa property for the presence of spodumene bearing pegmatites (a lithium source mineral), the potential of which was demonstrated by the 2020 survey. The work will also test previously detected gold and tungsten anomalies.


Sampling lines spaced between 500 m and 2000 m are planned perpendicular to the dominant ice flow and up-ice of the anomalous results already detected. The spacing between samples takes into account the types of surficial deposits and till availability as indicated on the map below. Sampling lines, 2 km apart with samples taken at 250 m intervals, are planned in the northeast portion of the property to complete the regional sampling of the property.



The previous till sampling survey had revealed three significant tantalum anomalies with grain counts each exceeding one hundred tantalum minerals, mainly colombotantalites (niobium tantalum oxide mineral), with a maximum of 179 grains. These observations came from the 97 heavy mineral concentrates processed by the ARTGold method, an automated scanning electron microscope (SEM) mineral detection technology. This IOS proprietary technology has demonstrated its effectiveness in the region of the Pontax lithium deposit on behalf of clients including the Ministry of Natural Resources and Forests of Quebec.


Colombotantalite is a mineral found mainly in spodumene bearing pegmatites (the main source of lithium) of the LCT (Lithium-Cesium-Tantalum) type as well as in certain alkaline igneous rocks. Several occurrences of LCT pegmatites are present among the volcanic rocks of the southern segment of the LaGrande Subprovince, host to the Maskwa property.


About the Maskwa Property

The Maskwa property, 100% owned by Sirios, is located approximately 100 km southwest of Radisson and approximately 120 km east of Wemindji in Eeyou Istchee James Bay, Quebec. The property consists of 396 claims, covering a surface area of approximately 201 km2. In addition to the tantalum anomalies, the till survey carried out in 2020 identified three areas anomalous in gold, platinum group and tungsten minerals on the property. Such associations are considered indicative of certain significant types of gold deposits.
