GSN’s Chief Executive Officer, Sean Gregory, commented:
“The intercept of 59m @ 2.1 g/t gold is the best ever encountered at Southern Star. It demonstrates that we are onto a very significant gold deposit. The presence of wide, high-grade intersections at the footwall of the quartz dolerite target are helping to define the extent of the high-grade mineralisation and add to our understanding of the plunge geometry. More results are anticipated from a further 12 holes drilled at Southern Star and drilling is ongoing at One Weight Wonder and at other regional prospects across our 100% owned Duketon Gold Project.”

Introduction
Great Southern Mining Limited (ASX: GSN) (“ GSN ” or the “ Company ”) is pleased to announce the first results from its maiden Reverse Circulation (RC) drill program at Southern Star from its 100% owned Duketon Gold Project located 45km north of Laverton, Western Australia (Figure 2).
3,421m of Reverse Circulation (RC) drilling has been completed at Southern Star in this program so far. The purpose of this drilling is to establish continuity of mineralisation along strike and to define the extent of mineralisation which is still open to the north, south and at depth. Results in this announcement relate to the first 12 holes (1,635m) with assays still pending for another 12 holes drilled at Southern Star. On the back of this result, drilling is ongoing across GSN’s 100% owned Duketon Gold Project.

Technical Discussion
The recent RC drilling has intersected outstanding mineralisation in multiple holes at Southern Star (Figure 4). The drill campaign was designed to target the footwall quartz dolerite unit as this appears to be where the primary lode is present. Results from the first twelve holes have been received, exceptional, wide mineralisation has been intersected in multiple holes at this target location.

Southern Star deposit is hosted in a steeply east dipping fractionated dolerite sill, overturned and younging to the west (i.e. upside down) that is over 100m wide in areas. Within this dolerite sill the most fractionated part (the top), a quartz-magnetite rich unit up to 80m wide appears to be the preferential host of the gold mineralisation.
Best standout intersections of 59m @ 2.1 g/t Au including 9m @ 4.5 g/t Au and 16m @ 3.2 g/t Au from 53m was intersected in drillhole 21SSRC009 (Figure 5). Gold mineralisation is hosted in a steeply east dipping 345° trending quartz-dolerite unit which is approximately 80m wide. Major shearing is present, running the length of the drillhole with gold mineralisation being associated with the quartz veining and sulphides within the differentiated dolerite unit. High grade mineralisation is present at the footwall of the quartz dolerite with a high-grade interval of 16m @ 3.2 g/t Au including 3m @ 7.8 g/t Au.

Iron enrichment has been mapped throughout the Southern Star area and is pervasive around a set of northeast trending stacked quartz veins on the eastern edge of the mineralised quartz-dolerite. This iron enrichment is evident in the magnetic signature as a magnetic high directly east of Southern Star (Figure 3 insert). Iron enrichment present within the Southern Star quartz-dolerite provides an oxidized chemical composition favourable to wall rock reaction with reduced gold fluids, this is a well-understood host rock setting for major gold deposits in the Eastern Goldfields.
Two holes of the RC program were collared at a 160° orientation, designed to build a greater understanding of the plunge geometry of the high-grade mineralisation and to test the presence of northeast orientated ironrich quartz veins at depth. Mineralisation was intersected in both holes (noting apparent thicknesses); significant intersections are as follows:
-
19m @ 1.8 g/t Au incl. 6m @ 3.9 g/t Au from 64m in 21SSRC0001
-
Multiple intersections in 21SSRC0002:
-
12m @ 1.0 g/t Au incl. 2m @ 3.9 g/t Au from 69m
-
14m @ 1.1 g/t Au incl. 3m @ 3.0 g/t Au from 84m
-
12m @ 0.7 g/t Au incl. 1m @ 3.7 g/t Au from 114m
-
38m @ 0.6 g/t Au incl. 2m @ 4.5 g/t Au from 140m
Both holes displayed wide zones of mineralisation with the presence of a higher-grade core within the intervals. The orientation of the drillholes enabled a better understanding of the possible plunge orientation of the higher-grade shoots within a stockwork of quartz stringers. At this early stage, interpretation of the higher-grade shoot tends to be shallow plunging to the north west. Further work is underway to test for high grade mineralisation in this direction (Figure 6).

Ben Hur Deposit Analogue
Southern Star is analogous to the nearby Ben Hur and Rosemont (>1Moz) deposits, situated 4 and 24 kilometres north-west along strike respectively. Ben Hur has been the focus of Regis Resources’ recent drilling efforts culminating in a Mineral Resource estimate 390kOz @ 1.2 g/t Au (Figure 7, refer to ASX:RRL announcement 6/4/21).
All three deposits are hosted within the same quartz dolerite unit which can be traced through the Duketon Belt (Figure 2). The deposits display a very similar style of mineralisation, with the primary lode proximal to the sheared footwall of the quartz dolerite, with minor lodes forming parallel to it.

Next Steps
Southern Star is developing into a key asset for GSN. The scale of Southern Star is yet to be determined and GSN plan to aggressively explore Southern Star to expand mineralisation along the strike length and at depth.
Further assays are awaited from another 12 holes already drilled and drilling is ongoing.
The drill rig is now at the nearby One Weight Wonder prospect and on the back of these excellent results, is planned to return for further drilling at Southern Star as well as at other regional prospects across the Company’s 100% owned Duketon Gold Project.

Southern Star Background
Southern Star is part of Great Southern Mining’s (GSN’s) Duketon Gold Project which encompasses over 450km[2 ] of tenements, and tenement applications under exclusive irrevocable option, located in the Duketon Greenstone Belt north of Laverton in Western Australia.
Southern Star is only 4km along strike from the 390koz at 1.2 g/t Au Ben Hur Gold Deposit and further along strike from the >1Moz Au Rosemount Gold Deposit, both mines owned by Regis Resources (Figure 2, refer regisresources.com.au).
Southern Star was acquired by GSN as part of a larger tenement package in February 2021. Since then, the tenement has been granted, GSN’s exclusive option exercised, Ministerial approval granted, the tenement transferred into GSN’s name, a Program of Work (POW) for drilling has been approved, with a maiden drill program underway.
Southern Star was most recently explored by Duketon Mining Limited in 2017-18 via a program that discovered significant high-grade gold mineralisation. High-grades, up to 60g/t Au, were intersected as were substantial plus 50-gram-metre intersections, and in places more than 90-gram-metre intersections. Mineralisation occurs within 4m of the surface in places and high-grades are seen throughout the broader mineralisation (refer ASX announcement 2/2/21). These exceptional exploration results were yielded from less than 10,000m of RC drilling completed to date, which highlights the potential for additional mineralisation to be discovered through further drilling at Southern Star. Mineralisation is open both to the north, south and down dip. Previous high-grade intersections include:
-
15m @ 6.5 g/t Au incl. 4m @ 23.3 g/t Au
-
50m @ 1.8 g/t Au incl. 5m @ 9.2 g/t Au and 6m @ 2.9 g/t Au
-
50m @ 1.6 g/t Au incl. 17m @ 3.8 g/t Au
-
34m @ 2.3 g/t Au incl. 12m @ 5.3 g/t Au
-
25m @ 2.5 g/t Au incl. 5m @ 10.7 g/t Au
-
35m @ 1.4 g/t Au incl. 11m @ 2.9 g/t Au
-
12m @ 4.0 g/t Au incl. 8m @ 5.9 g/t Au
-
26m @ 1.6 g/t Au incl. 5m @ 6.3 g/t Au
-
15m @ 2.2 g/t Au incl. 4m @ 7.4 g/t Au
-
20m @ 1.5 g/t Au incl. 7m @ 3.5g/t Au

| Data spacing and | • | The drill hole spacing ranges is not systematic, however most holes are drilled at 250° |
| distribution | across the regional strike. Drill hole collar positions are based solely on the drilling of | |
| specific exploration targets. I | ||
| • | The RC drill holes were planned to test the extension or down plunge extension of the ore | |
| body. | ||
| • | Other RC drilling holes were designed over areas of interest from field mapping activities. | |
| • | Sampling of RC cuttings has been undertaken at 1m intervals at areas of interest, | |
| appropriate high-grade mineralisation. | ||
| • | The current drill hole spacing and distribution is not sufficient to establish the degree of | |
| geological and grade continuity appropriate for the Mineral Resource and Ore Reserve | ||
| estimation procedure and classification. | ||
| • | 4m sampling compositing has been applied to areas of less interest and for regional | |
| exploration holes. | ||
| Orientation of data | • | The drill holes have been designed to cross cut the main lithology 250° to maximise |
| in relation to | structural, geotechnical and geological data, with the exception of 21SSRC0001 and | |
| geological structure | • |
21SSRC0002. No drillingorientation and/or samplingbias has been recognised at this time. |
| Sample security | • | Logging has been carried out by GSN and contract personal who were always on-site |
| during drilling. | ||
| • | No third parties have been allowed access to the samples. | |
| • | Samples were shipped directly from site to a secure stored site in Laverton to undergo | |
| evaluation. | ||
| • | Select samples for geochemical analysis were transported from Laverton to Bureau | |
| Veritas in Perth where upon receipt the samples are officially checked in and appropriate | ||
| chain of custody documentation received. | ||
| All sample information is kept in paper and digital form. Digital data is backed up onto the | ||

Section 2 Reporting of Exploration Results
| Criteria | Commentary |
|---|---|
| Mineral tenement and | The tenement E38/3501 is in good standing and was granted on February 17 2021. Great |
| land tenure status | Southern Mining Ltd is the holder |
| Exploration done by | Relevant exploration done by other parties are outlined in the body of this report or previous |
| other parties | GSN ASX announcements. |
| Geology | Mineralisation at Golden Star occurs as several stacked lenses within a sequence of foliated |
| sheet-like gabbroic intrusive units and is associated with quartz veining and sulphide alteration | |
| between two strike parallel shear zones. The deposit is hosted in a fractionated dolerite sill, | |
| overturned and younging to the west that is over 100m wide in areas. Within this dolerite sill the | |
| most fractionated part, a quartz-magnetite rich unit up to 80m wide, appears to be the | |
| preferential host of the gold mineralisation. | |
| Drill hole Information | All the drill holes reported in this report are summarized in in the report |
| Easting and northing are given in MGA94 – Zone 51 coordinates. | |
| RL is AHD | |
| Dip is the inclination of the hole from the horizontal. Azimuth is reported in magnetic degrees as | |
| the direction the hole is drilled.. | |
| Down hole length is the distance measured along the drill hole trace. Intersection length is the | |
| thickness of an anomalous gold intersection measured along the drill hole trace. | |
| Hole length is the distance from the surface to the end of the hole measured along the drill hole | |
| trace. | |
| Data aggregation | Significant assay intervals are recorded above 0.1g/t Au with a maximum internal dilution of 2m. |
| methods | no top cuts applied. |
| A breakdown of the high-grade Interval is shown in the body of the report. | |
| Relationship between | All significant intersections are quoted as downhole widths. The mineralisation has a near |
| mineralisation widths | vertical orientation most holes are drilled at a -60-degree dip which is industry standard. |
| and intercept lengths | All lengths are reported as downhole and the section in the body of the report displays the |
| relationship between drill hole angle and mineralisation interpretation. | |
| Diagrams | Relevant Diagrams are included in the body of this report. |
| Balanced reporting | All matters of importance have been included. |
| Other substantive | All relevant information has been included. |
| exploration data | |
| Further work | Future exploration includes assessment of recent drill results. Mineralisation is open along strike |
| and at depth. Diagrams highlight potential area of interest for follow up work. |
