St George Mining Limited (ASX: SGQ) has announced that lithium exploration is underway again at its flagship Mt Alexander Project in Western Australia.
St George’s landholding has extensive exposure between the Mt Alexander greenstone sequence and the Copperfield Granite – part of a large, regional LCT corridor that hosts the major lithium discovery by Delta Lithium (ASX: DLI) at its nearby Mt Ida Project (14.6Mt @1.2% Li2O).
Field work is underway to test the new lithium targets – comprising seven contiguous exploration licences and one prospecting licence, all owned 100% by St George except for E29/638 (75% St George: 25% IGO) at the project.
“Our initial exploration at Mt Alexander has confirmed the presence of high-grade lithium as well as very thick pegmatites – up to 121m thick. These results support the potential for a large lithium bearing pegmatite mineral system,” John Prineas, St George Mining’s executive chairman said.
“Our field work will provide further information on the zonation, thickness, and distribution of pegmatites along the more than 16km stretch of the regional LCT corridor on our tenure.”
Field work is focused on an 8km-long zone around the Manta Prospect, where drilling intersected a 121m thick fractionated pegmatite; and a 4km-long zone of the Jailbreak Prospect, where drilling intersected multiple lithium-bearing pegmatites with values up to 1.8% Li2O and rock-chip samples returned values up to 3.25% Li2O4.
Assay results for drilling completed at the Jailbreak Prospect in late 2022 and early 2023 confirmed the presence of lithium pegmatites that commence near surface and continue to depths of up to 300m. High grades – up to 1.8% Li2O – were returned in the drill results, highlighting the potential of the pegmatite system. Results for laboratory assays of the first round of samples expected in four weeks.
