The Cali Lease lies within the Little Nahanni Pegmatite Group in the Northwest Territories, near the Yukon border, and was acquired in 2022 with the Yellowknife project.
Size potential of the Cali pegmatite could be up to 1200 m x 60 m x 300 m
The Cali pegmatite was mapped by CSEL in 1977 and described as outcropping over a 500 meter strike length, having a 300 meter outcropping vertical extent, and up to 100 meter widths. Panels of metasedimentary country rock occur within the spodumene-bearing pegmatite, which has been described to have 60 meters of pegmatite dyke material. Float mapping suggests that the lithium-bearing dyke could be up to 1,200 meters in strike length.
The Little Nahanni Pegmatite Group has been noted to have greater than 275 complex rare element pegmatites over an area of 13 by 2.5 kilometers. CSEL also held the Cali pegmatite in the 1970’s which subsequently was acquired during the portfolio acquisition in 1983.
Field visit completed by Li-FT in June 2023 confirms historic work – Cali is a spodumene pegmatite dyke swarm with many dykes occurring over a 150 m wide corridor.
In August 2023, Li-FT commenced surface exploration program, which has been designed to better understand the average grade across the dyke’s exposed strike length to 300 metres vertical with systematic rock sampling and mapping. Prospecting for other parallel dykes and dyke extensions trending onto the Cali project from the south will also be carried out through detailed soil sampling.
Li-FT plans to integrate the data collected into a 3D geology model for exploration targeting and planning for an exploration/resource definition drill program in summer 2024. The Company is in the final stages of a Land Use Permit application for advanced exploration activities which includes drilling.
