Augustus Minerals’ (ASX: AUG) review of soil sampling data completed by the company has returned high tenure lithium and rubidium results in and around the Peak Bore prospect area within its T-Tree Project in Western Australia.
The programme has confirmed multiple lithium and pathfinder element anomalies within a zone approximately 7km x 6km which sits on and around a geologically complex flexure of the Ti-Tree shear.
Samples were collected on north-south oriented lines at a spacing of 100m x 400m.
The vast majority of the 7km by 6km soil anomaly is covered by thin soil cover. Basement rocks contain a mixture of Durlacher and Moorarie granites, as well as doleritic and felsic dykes and sills.
Encouragingly several occurrences of both Leake Spring Metamorphic and mafic greenstone have been found outcropping within parts of the anomaly coincident with higher grade portions of the anomaly.
More importantly, the Thirty-Three Supersuite granites which are presumed to be the source of all spodumene pegmatites in the Gascoyne region are in close proximity, just a few kms to the east, with the Delta Lithium Yinnetharra Lithium deposit 40km away along strike.
This large lithium anomaly continues our strategy for searching for new critical mineral targets in the Gascoyne,” Andrew Reid, Managing Director, said.
“Results from the soils confirm the presence of lithium and more importantly key pegmatite pathfinder elements, overlaps the Ti-Tree Shear for which Augustus holds 85km of strike length, and contain the same rocks which host the Yinnetharra Lithium Deposit.
“Our technical team is already working up exploration programs for 2024 and will use this data to redefine our priorities in this area.”
Augustus has ~3,600 sq. km of tenements located in the Gascoyne Region of Western Australia with an array of high quality drill targets which is highly prospective for lithium, rare earths and copper.
