St George Mining Ltd (ASX:SGQ) has identified new lithium targets and expanded the tenure of the Myuna Rocks Project in the Ravensthorpe region of Western Australia.
The new targets are in a prospective corridor of more than 50 kilometres, along strike from the spodumene-producing Mt Cattlin Mine.
"Exciting growth emerging"
St George Mining executive chairman John Prineas 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 546 square kilometres, 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 $11 billion ASX-listed Arcadium Lithium.
“Importantly, Myuna Rocks covers more than 50 kilometres of a major structural corridor that hosts Mt Cattlin and extends north to IGO’s Forrestania nickel complex. We are fortunate to have more than 50 kilometres of this underexplored belt in our tenure.
“The results of the recent airborne magnetic survey corroborate our belief that Myuna Rocks is prospective for significant lithium mineralisation.
“The late-stage granite intrusion at Myuna Rocks is in a sheared contact with the greenstones – a textbook geological setting for lithium mineralisation. This warrants immediate exploration follow-up, with St George committed to mapping and surface sampling ahead of a maiden drill program."
Myuna Rocks tenure doubles
St George has confirmed that exploration licences E74/789 and E74/790 have now been granted, increasing the granted tenure at Myuna Rocks by a further 273 square kilometres to a total contiguous area of 546 square kilometres.
“We are excited about the potential at Myuna Rocks and look forward to progressing our exploration programs in 2024,” Prineas added.
Project-wide survey identifies targets
New targets were identified via a new aero-magnetic survey with 6,200 line kilometres flown – the first high-resolution survey over the previously underexplored project area.
The company outlined the geological and geophysical features supporting prospectivity for lithium mineralisation that were interpreted from the survey data, including:
- A late-stage granite intrusion – covering an 18-kilometre x 8-kilometre area – within the project tenure that could be a source of potential lithium mineralisation.
- Extensive greenstone sequences interpreted adjacent to the granite, creating a contact with the granite that is a priority exploration area for lithium.
- Regional-scale northwest trending domain boundaries, similar to those known to act as a control on lithium and gold mineralisation in the Yilgarn Craton.
