St George Mining Limited announced this year's field programme for lithium exploration has commenced at its Mt Alexander Project in WA's Goldfields. 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 mineralisation within the project. 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 promoted levels of caesium, tantalum and rubidium - a geochemistry highly indicative of fractionated pegmatites prospective for lithium mineralisation. 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.

the broad area that 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.

The following work programmes are current and/or planned for 2023. The experienced significant delays with laboratory assays and now expect to receive final assays during February. 1. Assays for soil surveys at E29/962.

These have the potential to identify a lithium signature in an area where pegmatites are not exposed due to cover. 2. Assays for completed rock chip sampling of pegmatites. 3. Assays for the 2022 RC and diamond drilling programmes.

4. Further field mapping and rock chip sampling, already underway.
