St George Mining Ltd (ASX:SGQ) has outlined expanding lithium potential at the Mt Alexander Project in Western Australia, having identified more lithium outcrops across a 15-kilometre zone of pegmatite dykes.
The company collected a further 119 rock chip samples from two exploration licences within the project, with visual observations indicating there may be lithium mineralisation present in the form of spodumene and lepidolite, hard rock forms of lithium.
SGQ has submitted these samples to the laboratory for formal analysis and will also use x-ray diffraction (XRD) analysis with a portable spectrometer to generate initial mineralisation estimates.
Early observations combined with exploration completed by Red Dirt Metals at the nearby Mt Ida Project suggest to St George that Mt Alexander may form part of an underexplored lithium province.
“Significant lithium potential”
“We are delighted that our exploration team is continuing to deliver success in identifying pegmatite outcrops that appear highly prospective for lithium mineralisation, providing support for Mt Alexander’s significant lithium potential,” St George Mining executive chair John Prineas said.
“We are seeing thick pegmatite dykes spread over a zone more than 15 kilometres long in the same corridor parallel to the Copperfield Granite where major discoveries have been announced by Red Dirt Metals.
“We are increasingly excited by the potential that Mt Alexander may form part of the same pegmatite-hosted lithium mineral system.
“Our fieldwork is the first lithium-focused exploration conducted at Mt Alexander and we are very pleased with the pace at which the evidence for the lithium potential is building.
“This lithium work is a fantastic complement to our nickel exploration at Mt Alexander, which is progressing in parallel with a fixed loop electromagnetic survey scheduled to start next week. This will enable final modelling of several promising nickel targets for drill testing.
“With lithium and nickel drilling planned at Mt Alexander for Q4 2022, it is an exciting time for shareholders.”
St George has also begun soil sampling east of the pegmatite outcropping zone to test for possible extensions of the dykes below cover.
