Nb-Ta Rare Earth Element Carbonatite
The 91,107 ha Saguenay Project in Quebec is located within the north-western Proterozic Grenville province, and was acquired through staking in 2022 and 2023. A portion of the Project is adjacent to the Crevier Nb-Ta rare earth element (REE) carbonatite deposit, located along a major terrane-parallel structure at the intersection of terrane perpendicular structures. Regional magnetic data shows several anomalies highlighting extensive intrusive complexity, and coincident Nb-La-Ce lake sediment anomalies over the Project area indicate the potential for discovery of a syenite-carbonatite hosted REE deposit.
Location and Access
The Project area is located in the Saguenay-Lac Saint Jean region of Quebec, 125km northwest of the city of Saguenay. Extensive forestry activities in the area provide road access to all tenures in the Project area. Nearby infrastructure includes several towns and power transmission lines within 25km of Project boundaries.
Geology and Mineralisation
The Saguenay Project is located within the Proterozoic Grenville province, a series of terranes accreted to the eastern boundary of the Archean Superior province in the early Proterozoic. Successive deformation events include the middle Proterozoic Grenville Orogeny, and late to post-Grenville episodes of continental rifting responsible for emplacement of alkaline syenite-carbonatite intrusive complexes. Significant intrusive complexes include the Crevier Alkaline Complex (ca 985-950 Ma), and the St Honore Alkaline Complex (ca. 650-500Ma), both host to Nb-Ta carbonatite style mineralisation. Within the Project boundaries dioritic, granitic, syenitic and anorthosite intrusives predominate, and structures associated with continental rifting include the prominent northwest trending Saguenay Rift Zone (SRZ).
Significant REE mineralisation occurs immediately adjacent to the Project at the Crevier deposit; Nb-Ta mineralisation hosted in a series of porphyritic nepheline syenite dykes. Elsewhere with the region the Niobec producing mine and the Ste-Honore deposit represents a distinct geological setting of REE mineralisation hosted within calcitic-dolomitic carbonatites, associated with syenitic intrusives.
Limited exploration work has been completed. Within the Project boundaries only 13 historic drillholes have been drilled, no systematic project-scale geochemical or geophysical surveys have been completed.
Summary of exploration activities conducted by Kenorland Minerals
Since acquiring the Project, Kenorland has begun compilation and digitization of historical geological and geochemical data for the Saguenay area.
