Great Southern Mining Limited announced recent results of a multi-element soil survey conducted at its Duketon Gold Project, located 60km north of Laverton, Western Australia. GSN's Southern Star deposit is located on the prolific Rosemont-Ben Hur Trend, with Southern Star only 4km along strike south of the +300koz Au Ben Hur deposit owned by Regis Resources Limited. With GSN's multi-element soil survey so far identifying four compelling new targets within ~1.5km along strike north of Southern Star, drill design work is now underway with drilling targeted for Second Quarter FY23 to test down plunge extensions of the Southern Star deposit and a potential repeat of Southern Star.

During June 2022, a 300-sample soil program was completed along strike north of Southern Star. Samples were taken on a 100m wide line spacing, 50m apart. Based on a combination of the recently gained geological understanding and the available (new soils and old vacuum) geochemical data, four new targets areas are apparent.

Drilling along the trend by previous explorers appears to be limited to shallow ~80m wide spaced RAB and aircore drilling, making previous exploration ineffective. The new gold in soil anomalies have not been drilled and the Company is planning further RC drilling to test the northern strike extensions and depth potential at Southern Star. Multi-element analysis results from the recent drilling has also been used to vector in on mineralisation at these compelling targets.

An extensive multielement soil program is also currently underway south of Southern Star. The use of trace level multielement soils was pivotal in defining the Amy Clarke Prospect and this same technique will be used to test the strike on this well recognised mineralised corridor. GSN shares the Duketon Greenstone Belt with gold producer Regis Resources Limited, which has been successful in the identification of +8Moz of gold resources.

The majority of these deposits reside on major well understood shear zones. GSN's tenure in the Duketon Greenstone Belt includes significant portions of these shear zones and through the use of magnetic data and geological mapping, GSN immediately identified these shear zones as high priority target corridors and have aggressively begun to explore these well understood trends. It is interpreted that all three mineralised corridors continue into GSN's tenure, including: ~8km of the Erlistoun Trend, ~7km of the Garden Well Trend, ~12km of the Rosemont-Ben Hur Trend.

Southern Star resides on the Rosemont-Ben Hur Trend and is only 4km south of Ben Hur. This prolific trend has produced well over 1.5Moz of resources for Regis Resources Limited. The successful drill results at Southern Star to date, in combination with its position along strike from other significant deposits, has demonstrated a potential mineral resource development at Southern Star is emerging.
