Perth-based explorer Fin Resources (ASX:FIN) has staked 7 additional claims considered ‘highly prospective’ for lithium-caesium-tantalum (LCT) pegmatites at its Ross Lithium Project in Quebec, Canada.
The company reports the claims were secured following a review of historical results that identified several rock chip samples with elevated tantalum and caesium, which provides further evidence that fertile LCT pegmatites are likely present across the Ross Project.
Fin Resources engaged consultant Dr Neil Pendock to complete multispectral analysis across the Mount Tremblant Lithium Projects, which include the Cancet West, Gaspe, and Ross projects.
Results have now been received for Ross, where a ‘significant’ number of exploration targets interpreted as potential LCT pegmatites have been mapped. A spectral unmixing of a September 2022 Sentinel-2 scene has produced 2 minerals, interpreted as hectorite and spodumene, which are spatially correlated with nearly 109 rock chip samples within the region of interest assayed for lithium from the government geochemistry database.
Fin reports the results of this historical work and the recent work completed by Dr Pendock have highlighted that the Ross Lithium Project appears to be ‘highly prospective’ for lithium and rare earth element (REE) mineralisation.
Commenting on the results, Fin Resources Director Jason Bontempo says: “The Ross Lithium Project has significantly exceeded our expectations since acquisition. Further desktop review, including compilation and overlay of the results of historical work and recent satellite imagery completed, now presents the Ross Lithium Project to be highly prospective for lithium and REE mineralisation.

This work has identified a significant number of possible pegmatite outcrops which FIN will immediately begin planning fieldwork to commence in the third quarter.”
Fin reports a ‘comprehensive’ desktop review of the historical exploration data available across the project identified a ‘significant’ number of pegmatitic granites that have been mapped across the project by Canadian government geologists and previous private sector explorers.
Of particular importance is the frequency of fractionated and altered felsic rocks observed within the project, which the company considers to be ‘very encouraging’, including several coarse-grained pegmatites. Additionally, tourmaline, molybdenum crystals, and biotite have been logged throughout the tenure within coarse-grained pegmatites and granites.
Meanwhile, a 2009 report submitted to spatial reference geomining information system SIGEOM by Landmark Minerals mapped pegmatite outcrops throughout Ross while exploring for uranium. Samples taken from the mapped pegmatite outcrops were assayed for lithium, associated LCT pegmatite pathfinders, and REEs, with several samples returning results for cerium above the detection limit.
Fin Resources is a Perth-based company focused on developing its Sol Mar Project in the Pilbara region of Western Australia. Along with Sol Mar, the company also holds the McKenzie Springs Project in the Kimberley region of Western Australia.
In Canada, Fin recently acquired the Mount Tremblant Lithium Project package in the James Bay region of Quebec. The Ross Lithium Project covers over 30km of strike length of an underexplored greenstone belt located along strike to the east of the neighbouring Whabouchi lithium deposit.
