GR lithium pegmatite dyke cluster consists of three lithium pegmatite dykes located on the west side of the Crowduck Bay Fault
The GR-1 dyke was drill tested in 1942 to a depth of 50m and the dyke remains open at depth.
Drill results of 1.84% Li2O over 6.32 meters at GR
The Grass River (GR) lithium pegmatite was discovered in August of 2018 by routine prospecting and is interpreted to be part of the GR lithium pegmatite dyke cluster
Drill results of 3.35% Li2O over 3 meters and widths of 5 to 6 meters
Over 15,000 meters of drilling was conducted to test the GR dykes in 2022.
Metaulligurcial testwork from the grass river project demonstrates 83.5% lithium recovery producing a 6.39% li20 spodumene concentrate.
