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.
The Cali pegmatite was mapped by CSEL in 1977 and described as outcropping over a 500 m strike length, having a 300 m outcropping vertical extent, and up to 100 m widths. Panels of metasedimentary country rock occur within the spodumene-bearing pegmatite, which has been described to have 60 m of pegmatite dyke material.
The Little Nahanni Pegmatite Group has been noted to have greater than 275 complex rare element pegmatites over an area of 13 km by 2.5 km. 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 m 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.
During the summer surface program in 2023, LIFT completed a soil geochemistry survey covering the Cali Property, as well as a mapping and prospecting campaign. Rock sampling and mapping indicate that the spodumene pegmatite dyke swarm system is larger than had been anticipated with numerous spodumene pegmatite swarms present within an area of 1.5 km by 1 km. Out of 163 grab samples collected, 124 returned grades at greater than 1.0% Li2O.
The Company has secured the Land Use Permit to conduct advanced exploration activities which includes drilling.
