Mar 21, 2023 (Paul Malegus) - This occurrence was reported from Frontier Lithium's January 31, 2023 news release. Additionally, the RGP visited the site on August 12, 2022 with Frontier Lithium staff. The pegmatite covers an area of 10 x 15 m, composed of spodumene, quartz, muscovite, +/- lepidolite, tourmaline and garnet. Additionally, the company notes the spodumene has a "snowshoe" texture. In a company presentation on June 14, 2023, it was suggested that this zone may actually be a really large erratic.
