Montreal (Québec) – The directors of Sirios Resources Inc. (TSX-V: SOI) are pleased to announce the presence of significant tantalum anomalies in till samples from the survey carried out on its Maskwa property in 2020. In this 97-sample survey, three anomalies were identified, each with significant grain counts exceeding one hundred tantalum bearing mineral grains. A total of 3,310 grains, were observed, mainly Columbo-Tantalites (niobium and tantalum oxide mineral), averaging 34 grains per sample with a maximum of 179 grains (see map below). These observations come from the 97 heavy mineral concentrates processed by the ARTGold method, an automated mineral detection scanning by electron microscope (SEM), a technology exclusive to IOS Services Geoscientifiques Inc. of Saguenay, Quebec.
Columbo-Tantalite is a mineral present mainly in spodumene-bearing pegmatites (spodumene being 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 that host the Maskwa property.
IOS Services Geoscientifiques recently demonstrated the effectiveness of its ARTGold till processing technique in the region of the Pontax lithium deposit on behalf of clients including the Quebec Ministry of Natural Resources and Forests. Among other things, the tests succeeded in capturing the tantalum mineral signature in the till from known lithium showings in the rock. Grain counts in excess of 100 in an area where the average is approximately thirty grains per sample represent anomalies potentially indicative of kilometric distal sources. On the Maskwa property, the till lines currently spaced between 4 and 6 km leave sufficient space to consider the potential presence of spodumene-bearing pegmatites on the property.
Sirios geologists are currently planning the follow-up work required based on these encouraging results.
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 Baie-James, 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 by IOS Services Geoscientifiques identified three areas anomalous in gold, platinum group and tungsten minerals on the property. Such associations are considered indicative of certain types of gold deposits.
