Redstone Resources (ASX: RDS) has obtained promising results frtom recently completed prospectivity analysis, which has identified a significant number of high priority Lithium‐Caesium‐Tantalum (LCT) pegmatite target areas on the Radisson East Lithium Project and Sakami Lithium Project (collectively the Projects) in James Bay, Québec, Canada.
Redstone retained Mercator Geological Services to complete their proprietary prospectivity analysis method on Sakami and Radisson East Projects, identifying 18 target areas and six target areas respectively on the projects.
The Sakami Lithium Project (68 sq. km) consists of three claim blocks within the La Grande sub‐province situated approximately 14 km north of the boundary between the La Grande and Opinaca sub‐ provinces, in a similar geological setting as the Corvette, Cancet and Adina lithium deposits, which all occur 10 to 20 km north of the boundary.
The Radisson East Lithium Project (22 sq. km) consists of two claim blocks, both within the La Grande sub‐province and 55 km to the northeast of Q2 Metals Corp.’s Mia Lithium project.
The primary purpose of this prospectivity analysis was to identify priority lithium targets within the Projects to guide further exploration. The prospectivity model used was designed on the LCT (lithium‐ cesium‐tantalum) pegmatite deposit model of Černy & Ercit (2005)1, and review of data from the known lithium deposits in the area. The final version of the prospectivity map consisted of 79 input layers of data sourced from the Government of Québec’s Geomining Information System (SIGÉOM) that were used to calculate the prospectivity weightings. The model was designed to highlight the best lithium targets where favourable structure, lithology, mineralisation, and LCT pegmatites geochemistry occur.
A preliminary field programme will be completed over the projects to assess the highest prospectivity target areas identified from this prospectivity analysis, in conjunction with the significant number of potential LCT pegmatite outcrop targets identified by multispectral analysis recently announced.
The first pass programme will include field mapping, outcrop sampling and geochemical sampling to verify the presence of pegmatite outcrops and to test for lithium mineralisation.
