St George Mining Limited (ASX: SGQ) has identified new lithium targets in a +50km prospective corridor along strike from the spodumene-producing Mt Cattlin Mine at Ravensthorpe, WA. This marks a significant expansion of the company’s Myuna Rocks Project, which is owned 100% by Lithium Star Pty Ltd, a joint venture between St George (90%) and Amperex Technology Limited (10%), the world’s leading producer of lithium-ion batteries.
The Myuna Rocks tenure has doubled in scale with the granting of exploration licences E74/789 and E74/790. This increases the granted tenure at Myuna Rocks by a further 273km2 to a total contiguous area of 546km2. The Myuna Rocks land package commences 5km north of the Mt Cattlin Lithium Mine tenure and extends for more than 50km to the north-west along a regional greenstone corridor.
In addition to the spodumene-producing Mt Cattlin mine of global lithium major Arcadium Lithium (ASX: LTM), active explorers in the region include Fortescue (ASX: FMG), NickelSearch (ASX: NIS) and Woomera Mining (ASX: WML).
A project-wide aero-magnetic survey has been conducted, with 6,200-line km flown. This is the first high-resolution survey over the previously underexplored project area. Geological and geophysical features supporting prospectivity for lithium mineralization have been interpreted from the survey data.
These features include a late-stage granite intrusion, covering an area 18km x 8km, within the project tenure that could be a source of potential lithium mineralization. Extensive greenstone sequences have been interpreted adjacent to the granite, creating a contact with the granite that is a priority exploration area for lithium. Regional-scale north-west trending domain boundaries, similar to those known to act as a control on lithium and gold mineralization in the Yilgarn Craton, have also been identified.
John Prineas, St George Mining’s executive chairman, said: “We are very pleased to see exciting growth emerging at the Myuna Rocks Project – both in terms of the large scale of the project tenure and the newly identified target areas which demand immediate exploration follow-up. Maiden drilling is being accelerated to Q2 2024. The Myuna Rocks tenure now spans a contiguous area of 546km2, making it one of the largest single landholdings in the region – larger than the area of the nearby Mt Cattlin mine owned and operated by the A$11B ASX-listed Arcadium Lithium.”
