Sep 18, 2023 (Paul Malegus) - The occurrence is located over a 3 km strike length, with multiple spodumene and/or beryl pegmatites mapped. Pegmatites are located primarily along the contact between the peraluminous Wenesaga Batholith and the adjacent metasedimentary units. All pegmatites to date have been found within the English River subprovince. 205 pegmatite outcrops have been mapped and the structural trend is on strike with the Sandy Creek Pegmatite (MDI52K11NW00004) (Beyond Lithium, news release, September 18, 2023).
