Mar 21, 2023 (Paul Malegus) - The RGP visited the site on August 12, 2022 with Frontier Lithium staff. Two samples were collected, 22TG0050 returned the following results: 3.08% Li2O, 0.003% Cs2O, 0.09% Rb2O, 55 ppm Ta2O5, 43 ppm SnO2, and 63 ppm Nb2O5 (Frontier Lithium, January 31, 2023 news release). 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. Initial parallel channel sampling was completed in 2023, returning 2.16% Li2O over a combined 18 m. In 2024 Frontier Lithium drilled below the channel samples and intercepted pegmatite 40 m below, with drillhole PL-138-24 intersecting 1.43% Li2O over 18.8 m (Frontier Lithium, news release, November 19, 2024).
