Great Southern Mining Limited announced that at its AGM held on June 2023, the company has continued its efforts in undertaking carefully considered exploration programs efficiently and effectively during the year, including a successful Air Core program in 2023 discovering new mineralised gold trends at the Duketon Gold Project. The East Laverton Nickel Project has been progressed with electromagnetic (EM) surveys undertaken during the year, as well as a small diamond program executed in November 2022 which targeted the conductors identified through EM surveys. The Company has planned aggressive exploration programs at Golden Boulder and Southern Star in Financial Year 2024 to delineate gold ounces and generate significant news flow.

All exploration programs will be executed in line with funding requirements and appropriate capital management. The Company completed several drill programs at multiple projects in Western Australia throughout the year ending 30 June 2023 and is well placed to continue to advance its projects along the value curve. A summary of the Company's projects and main exploration activities during the period are provided below: Great Southern Mining holds Exploration Licences totalling 269km2 in the Duketon Greenstone Belt located to the north of the town of Laverton in Western Australia.

The Company shares the belt with gold producer Regis Resources Limited, which has been successful in the identification of +8Moz of gold mineral resources. It is interpreted that the three primary mineralised corridors in the belt continue into GSN's tenure, incorporating ~8km of the Erlistoun Trend, ~7km of the Garden Well Trend and ~11km of the Rosemont to Ben Hur Trend. The Company is exploring primarily for gold with three advanced exploration areas including Southern Star, Amy Clarke and Golden Boulder.

Southern Star: GSN has defined gold mineralisation over a 700m strike extent at the Southern Star prospect, which is located just 3km south and along trend from Regis Resources ~390koz Ben Hur gold mine. To date, Southern Star has only been shallow drilled with most holes ending less than 140m below ground surface. Better results from previous drill campaigns include1: · 59m @ 2.1g/t Au from 53m, including 9m @ 4.5g/t Au and 16m @3.2g/t in 21SSRC0009 · 68m @ 1.9g/t Au from 61m, including 4m @ 15.3g/t Au and 5m @ 7.0g/t in 21SSRC036 · 17m @ 7.0g/t Au from 111m, including 2m @ 56.7g/t Au in 21SSRC0039 Southern Star remains open in nearly every direction and the Company's understanding of the controls on mineralisation are still in its infancy.

Future drilling will test extensions to mineralisation at depth and along strike to the north and south. GSN has also identified the potential for mineralisation to the west on a parallel trend, which is interpreted to be on the same trend as RRL's Ben Hur deposit to the north.
