Sampling results at Mt Alexander show strike length of >2.7km
More than 500 pegmatite outcrops mapped to date
Drilling at newly discovered targets planned for next month
Special Report: Soil sampling results from St George Mining’s Mt Alexander project have discovered multiple new, large-scale lithium soil anomalies – the largest of which has a strike length of >2.7km.
The Mt Alexander project is 120km south-west of the Agnew-Wiluna belt, which hosts numerous world-class lithium deposits such as Delta Lithium’s (ASX: DLI) 14.6Mt Mt Ida resource and abuts the Mt Bevan project joint venture between Gina Rinehart’s Hancock Prospecting, Legacy Iron Ore (ASX:LCY) and Hawthorn Resources (ASX: HAW).
Soil sampling results
Following on from drilling in late 2022 and early 2023 at the Jailbreak prospect where St George Mining (ASX:SGQ) confirmed the presence of lithium mineralisation from near surface (down to 300m and grading up to 1.8% Li2O), soil sampling has uncovered large-scale lithium soil anomalies.
The largest of these has a strike of >2.7km. The lithium values also correspond to anomalous values of caesium and tantalum (LCT). One of the new anomalies is 1.7km x 1.3km and along strike from the Manta prospect where drilling intersected a 121m thick pegmatite.

The survey included the E29/1143 and P29/2680 tenements acquired in late 2022. SGQ believes it’s the first-ever systematic exploration for lithium in the area.
The survey area in the south represents a 4km-long zone along strike from where drilling by SGQ has already intersected multiple lithium-bearing pegmatites at Jailbreak.
Meanwhile, the larger survey area in the north covers more than 10km of the contact between the Copperfield granite and the Mt Alexander ultramafic sequences, including a large zone around the Manta prospect.
The results have borne four new high-priority soil anomalies at Jailbreak West, Mt Alexander East, Manta East and Manta – all of which carry lithium anomalies and are associated with pathfinder elements – particularly tantalum and caesium.
Positioning for a resurgence in market conditions
SGQ executive chairman John Prineas said the company was delighted to have delineated “not just one but a series of” multi-kilometre lithium soil anomalies that warrant testing with the drill bit.
“The consistency and cohesiveness of the lithium values within these large-scale anomalies is impressive,” Prineas says.
“The coincident pathfinder elements like tantalum and caesium, as well as the extensive pegmatite outcrop make these areas compelling drill targets.
“Drilling approvals are in place and we look forward to testing these promising targets very soon.”
