St George Mining Limited (ASX: SGQ) has kicked off this year’s field programme for lithium exploration at its Mt Alexander Project in Western Australia’s Goldfields.
“We are pleased to have boots on the ground again at Mt Alexander as we kick off our big exploration programme for 2023,” Executive Chairman, John Prineas, said.
“The extensive field mapping and sampling programme has continued to identify new pegmatite outcrop along the 15km pegmatite corridor in our project tenure.
the area at the Jailbreak Prospect that hosts pegmatite outcrop with high-grade lithium.
“The rock chip assay results provide further encouragement of the exploration upside at Mt Alexander.
“These host pegmatites will be priority drill targets in 2023 with drilling scheduled to start in late February.
“We are excited to have commenced the next chapter in our systematic exploration push at Mt Alexander.”
Further sampling and field mapping underway
Field exploration to identify high-grade lithium bearing pegmatites resumed at Mt Alexander on 15 January 2023. The field mapping and systematic sampling programme is occurring over the numerous outcropping pegmatites across the project tenure.
The area currently being explored is focused on the north-east margins of Exploration Licences 29/962 (100% St George) and 29/638 (75% St George: 25% IGO) as well as the area of the newly acquired E29/1143 (100% St George) that hosts the contact with the Copperfield Granite.
To date, 123 samples have been collected and submitted for laboratory assay in 2023.
The work indicates that the mapped surface widths of the pegmatites can be up to 20m and that the pegmatites dip moderately to the north. The exact nature of the pegmatites will be determined through drilling.
The mapping and sampling programme has targeted outcropping pegmatites covering an area of approximately 36 sq km, which continues to increase the prospective footprint for potential lithium mineralization within the project.
Assays confirm more lithium-bearing pegmatites
The latest assays for rock chip samples collected from pegmatite outcrop continue to demonstrate the prospectivity of the project area.
In addition to high-grade lithium, the geochemistry of rock chip samples returned strongly elevated levels of caesium, tantalum and rubidium – a geochemistry highly indicative of fractionated pegmatites prospective for lithium mineralization.
2023 drill programme
A major lithium drill programme is scheduled to commence later this month with more than 20,000m of drilling scheduled for H1 2023. There is capacity to escalate the drill programme in response to drill results.
A broad area will be targeted in the first phase of the 2023 drilling. This area hosts the repetitive and stacked lithium-bearing pegmatite outcrops that were drill tested in the initial lithium drill programme completed late last year.
The next phase of drilling will include a substantial programme testing down dip and along strike from the initial drill holes at the Jailbreak Prospect as well as testing new target areas within the pegmatite corridor.
Drilling will commence in the eastern margin of E29/962, an area close to the lithium source granites – a geological setting that is similar to the area that hosts Red Dirt Metal’s Sister Sam, Sparrow and Timoni lithium deposits approximately 20km to the south.
