St George Mining (ASX: SGQ) has unveiled promising new targets at its wholly-owned Destiny project in Western Australia’s Eastern Goldfields region.
The exploration efforts have identified potential carbonatites and mafic intrusions, raising the prospect of hosting niobium (Nb), rare earth elements (REE), or nickel-copper-PGE mineralisation.
A gravity survey program conducted by St George over six prominent magnetic features at the Destiny project has yielded significant results.
Four of the six magnetic features have shown a high-gravity signature, suggesting they could be intrusions such as carbonatites or mafic intrusions, both known globally for hosting valuable mineralisation.
These features, ranging from 0.9km to 2.7km in diameter, were identified through a detailed magnetic survey conducted by St George in late 2023.
Their proximity to the Ida Fault, a regional-scale crustal suture, indicates a potential conduit for intrusions and evidence of major structural disruption in the surrounding greenstone/granite belt.
Two of the features at Destiny share characteristics with known mineralised carbonatites in Western Australia, including the Mt Weld project of Lynas Rare Earths and the Luni carbonatite of WA1 Resources, which are located along major crustal structures.
St George’s recent drilling to the south of the interpreted intrusions has already confirmed high-grade REE mineralisation associated with the Ida Fault, extending over a strike length of more than 10km and remaining open in all directions.
Historic drilling has not effectively tested the coincident magnetic/gravity features, making them exciting drill targets for potential mineralisation.
Executive Chairman John Prineas expressed optimism about the findings, stating: “The combination of high-gravity signatures, magnetic geometry, and geological setting at Destiny warrants further investigation to determine the potential for any mineralisation to be associated with these distinctive geophysical features.
“These targets are relatively easy to explore and we consider they have potential for high-grade discoveries, such as Nb-REE mineralisation or Ni Cu-PGEs.”
Drilling has been prioritised to test these new targets, and St George Mining looks forward to providing updates on exploration as the project advances.
