New minor risk - Shareholder dilution The company's shareholders have been diluted in the past year. Increase in shares outstanding: 15% This is considered a minor risk. Shareholder dilution occurs when there is an increase in the number of shares on issue that is not proportionally distributed between all shareholders. Often due to the company raising equity capital or some options being converted into stock. All else being equal, if there are more shares outstanding then each existing share will be entitled to a lower proportion of the company's total earnings, thus reducing earnings per share (EPS). While dilution might not always result in lower EPS (like if the company is using the capital to fund an EPS accretive acquisition) in a lot cases it does, along with lower dividends per share and less voting power at shareholder meetings. Currently, the following risks have been identified for the company: Major Risks High level of non-cash earnings (32% accrual ratio). Revenue is less than US$1m. Minor Risks Share price has been volatile over the past 3 months (14% average weekly change). Shareholders have been diluted in the past year (15% increase in shares outstanding).

New minor risk - Share price stability The company's share price has been volatile over the past 3 months. It is more volatile than 75% of Australian stocks, typically moving 13% a week. This is considered a minor risk. Share price volatility indicates the stock is highly sensitive to market conditions or economic conditions rather than being sensitive to its own business performance, which may also be inconsistent. It also increases the risk of potential losses in the short term as the stock tends to have larger drops in price more frequently than other stocks.

Great Southern Mining Limited Provides Update on Exploration Programs for the Year Ended June 30, 2023 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. New Risk • Sep 03

Great Southern Mining Limited Announces New High Priority Targets Identified At Duketon Gold Project Great Southern Mining Limited has completed a detailed structural geology interpretation for the northern portion of the Company's 100% owned Duketon Gold Project, north of the town of Laverton in Western Australia (covering Exploration License E38/3518). This new interpretation, which was completed by GSN's Technical Consultant Marcus Willson, has highlighted five new, high priority gold exploration targets. These new targets are in addition to existing prospects with known high grade gold mineralisation, including Southern Star, Amy Clarke and Golden Boulder. GSN is planning to recommence drilling at the Duketon Gold Project in the first quarter of calendar year 2023. New High Priority Gold Targets at Duketon Gold Project: GSN has completed a detailed structural geology interpretation of the northern portion of the Duketon Gold Project. This interpretation was completed by consulting structural geology expert and Technical Consultant, Marcus Willson, and compiled using high resolution geophysical data, field mapping, existing drilling and publicly available studies on the Duketon Belt. The foundation to this structural interpretation is an orogenic reconstruction of the belt to define deep seated structures and gold bearing lineaments. Consequential to this interpretation was the delineation of five new, high priority gold target areas. All of these targets sit along mineralised trends which host gold deposits to the north within Regis Resources' Duketon Gold Mining project. A description of the five targets is provided below: Southern and eastern extension (possible splay) of the Golden Boulder prospect which hosts approximately 3km of historic gold working. Gold bearing reactivated faults (inversion faults) are interpreted to plunge to the south. The onset of a hard iron laterite crust over the southern portion of this target area is interpreted to geochemically mask potential underlying gold anomalism and to have impeded historic gold prospecting. Previous aircore drilling has rarely penetrated through the hard laterite and is therefore considered ineffective. The style of mineralisation is expected to be narrow, high-grade shear and quartz vein hosted gold similar to historic gold workings to the north Located on the Garden Well Trend. Aeromagnetic images show major north-south structures being offset by later NNW-SSE structures creating an interpreted analogous structural setting to Regis Resources' +3Moz Garden Well gold deposit to the north. Limited historic drilling is considered to be well south of the area of interest, therefore key structures remain untested. This target is located to the south of the existing Amy Clarke prospect along the Erlistoun Trend (host to the 320koz Erlistoun gold deposit to the north). It is interpreted to be on the hanging wall position to a major, shallow dipping thrust fault with an underlying deep intrusive centre which interacts with multiple north-south and northeast trending structures. Interpreted to be a ‘pop-up’ structure incorporating hanging wall anticlines and shallow thrust faults with evidence of underlying granites. Historical workings line a ridge running through this area on an interpreted back-thrust fault. There is limited historic drilling and previous surface geochemistry is considered ineffective due to transported cover. This target is located on the interpreted hanging wall to a shallow thrust, which to the north is understood to be the controlling structure of the Garden Well deposit. Focus in the area will be on cross-cutting NNW-SSE fault structures. High Impact Drilling Planned to Commence from March Quarter 2023: GSN is planning an intensive year of drilling at the Duketon Gold Project, commencing in the March quarter of 2023. The previous two years of target generation and early-stage exploration have laid the foundation for high impact drilling on prospects with known high-grade gold mineralisation. Planned drilling programs are detailed below. Southern Star Gold mineralisation at the Southern Star prospect has been defined over an 800m strike extent and remains open in nearly every direction. GSN plans to expand upon current mineralisation by testing four key areas including: · Depth extensions to known mineralisation below intercepts, such as 10m @ 3.1 g/t Au including 3m @ 8.6 g/t Au (21SSRC0012); · Directly north of the main mineralisation zone where geochemical surveys have delineated four gold anomalies; · A 700m long geochemical anomaly to the south of the current mineralisation zone; · A parallel trend to the west, which GSN interprets to be the trend hosting Regis Resources' Ben Hur deposit just 4km to the north. Golden Boulder area: The Golden Boulder area was identified by GSN in 2021 as a high priority prospect with over >3km of historical workings over several parallel and stacked trends. Historic drilling in the area is sparse and shallow, averaging just 40m below surface. Standout intersections from GSN's first pass 16- hole drilling campaign in 2021 returned intercepts including: 5m @ 3.3 g/t gold from 49m, including 1m @ 12.3 g/t gold and 1m @ 1.2 g/t gold from 73m in 21GBRC0001; 5m @ 1.2 g/t gold from 103m, including 1m @ 4.1 g/t gold in 21GBRC0007; 7m @ 1.2 g/t gold from 121m, including 2m @ 3.3 g/t gold in 21ERRCC0005. Rock chip samples collected along strike for historic working included grades of 241gt gold and 103gt gold. The Company is predicting narrow high-grade shear or vein hosted gold mineralisation with stacked and parallel lenses. GSN in planning aircore fence line drilling over approximately 3km of strike to vector in on zone of high-grade and contiguous zones of mineralisation. Amy Clarke A maiden aircore drill program was completed in early 2022, which included a best intercept of 5m @ 8.2 g/t gold, including 4m @ 12.5 g/t gold from 33m in hole 21ACAC147. This program, along with geochemical soil surveys has defined a 5km long gold anomaly. Follow-up RC drilling has been planned around zones of higher grade (proximal to hole 21ACAC147) to gain a better understanding on the controls on gold mineralisation. Further aircore drilling has also been planned over the recently defined 1.4km extension to the gold and pathfinder element anomaly resulting from a geochemical soil survey in 2022.

Great Southern Mining Limited Provides Exploration Update for its 100% Owned East Laverton Project in Western Australia Great Southern Mining Limited provided an exploration update for its 100% owned East Laverton Project in Western Australia. Drilling has now been completed for a three-hole program designed to test two bedrock electromagnetic ("EM") conductors within the Diorite Hill Intrusive Complex ("Diorite Hill"), namely Conductor L076 and Conductor L124. While drilling did not intercept significant quantities of nickel or copper sulphides, the Diorite Hill Complex has been proven to contain prospective mafic-ultramafic geology with no internal graphitic or sedimentary shale units (being potential sources of false-positive conductors). All three holes contained widely dispersed trace sulphides highlighting the fertile nature of the complex. Assays for precious metals are pending. Conductor L076 was drill tested with a 579.6m deep hole comprising a 274m RC pre collar with a NQ-size diamond tail. Drilling encountered a sequence of high magnesium basalts followed by gabbro and pyroxenite units, interpreted to be the Diorite Hill layered sequence. Trace (>0.2%) sulphides (pyrrhotite, pyrite and chalcopyrite) have been observed throughout the complex. The interpreted base of the Diorite Hill Complex was marked with a garnet pyroxenite gneiss from 285m to 289m downhole. The remaining geology of the hole comprised a sequence of foliated and pillow basalts. Pillow features indicate that the basalt sequence sits outside of the layered intrusion and supports the interpretation that hole 22ELRCD0001 has successfully drilled through the contact of the layered intrusion. Disseminated and vein iron sulphides were observed at various intervals throughout the mafic sequence with thin veins from 304.6m to 305.2m (up to 8mm) and wider, more prolific veins (up to 200mm) from 545.5 to 549m downhole. Chalcopyrite was observed at the 304.6 to 305.2m interval. Downhole EM could only be undertaken to a depth of 211m downhole due to a hole blockage, however this survey did reconfirm the presence of a significant conductor. Unfortunately, the downhole EM could not provide sufficient data to confirm if the sulphides from 545.5 to 549m were the source of this conductor. Conductor L124 was drill tested with two RC holes (22ELRC002 and 22ELRC003) for a total of 308m. Drilling intersected a suite of mafic and ultramafic horizons with two types of ultramafic observed, defined by their pyroxene or olivine composition. Trace (>0.2%) sulphides (pyrrhotite) were logged in 22ELRC002 from 62m to 100m and increased magnetite was observed in the same hole from 109-120m. Downhole EM could not replicate the previously defined surface EM conductor, which has now been reinterpreted as a near surface feature. While no significant nickel or copper sulphides were observed in holes 22ELRC002 and 22ELRC003, assays will be submitted to test for platinum group and pathfinder elements. Interpretation of magnetic imagery shows the position of the two RC holes to be proximal to a major stratigraphic break, from a magnetically unlayered sequence in the southwest of the complex to a magnetically-layered sequence in the northeast. Such major stratigraphic breaks are commonly the most prospective internal positions within differentiated mafic-ultramafic intrusions for PGE-enriched horizons. An analogy for this positioning of PGE enrichment within a layered intrusive is the Munni Munni deposit in Western Australia, depicted in Figure 4 below. GSN plans to conduct further work along, what it considers to be, a similar prospective horizon within the Diorite Hill Complex. It is important to note that electromagnetic tools are likely to be less effective for targeting PGE enriched units, therefore other methodologies such as detailed magnetics, geochemical vectoring and drilling will be considered for future exploration. The East Laverton Nickel Project also contains approximately 17km of virtually unexplored ultramafic stratigraphy along the Granite Well and Rotorua trends. These are considered prospective for Kambalda-style komatiite hosted nickel mineralisation. The Granite Well trend comprises of 10km of interpreted komatiitic ultramafic stratigraphy immediately west of the Diorite Hill intrusion, of which ~3km of strike is within GSN's tenure. Limited exploration has targeted Granite Well, however hole 94GWR245 on a neighbouring tenement to the north intercepted anomalous and coincident copper-nickel sulphides (20m at 0.28% Cu, 0.11% Ni from 12m, including 4m at 0.34% Cu, 0.16% Ni). In addition, multiple shallow historic holes along this trend have nickel values above 0.2% with no drilling on the 3km portion of GSN's tenure. The Rotorua ultramafic trend consists of a 14km long ultramafic sequence extending south from the Diorite Hill Complex. No historical nickel focussed exploration has been conducted over Rotorua, however limited shallow gold focussed aircore drilling on the western margin of the ultramafic stratigraphy showed anomalous nickel (0.2-0.3% Ni) in base of holes samples. Drillhole RRLBVAC054 was also assayed for platinum and palladium with a peak value of 115ppb Pd+Pt. The presence of komatiitic spinifex textures were also noted in base of hole logging. The Company plans to undertake moving loop EM (MLEM) surveys on both the Rotorua and Granite Well komatiite trends. Both surveys have now been designed and costed with surveys likely to take place in early 2023 in conjunction with any follow up exploration of the Diorite Hill Complex. While gold exploration at East Laverton is not the immediate focus, it is noteworthy that Brightstar Resources' Alpha deposit (1.4 million tonnes at 2.3g/t gold for 106,000 ounces) resides on the southern edge of the East Laverton tenure. The strike extent of this mineralised trend extends into GSN's ground and has not been effectively explored. Further, a review of historical datasets has also demonstrated the potential for orogenic gold, with intercepts such as 9m at 2.4g/t gold, including 5m at 4.2g/t gold from 48m (EIC001, WAMEX A48007) reported from historic drilling in the east of the project area.

Great Southern Mining Limited Announces Drilling Underway to Test EM Conductors At the East Laverton Nickel Project Great Southern Mining Limited advised that drilling will commence this week at the Company's 100% owned East Laverton Nickel Project ("EastLaverton"), located approximately 35km east of the town of Laverton. This drilling campaign will test two bedrock electromagnetic ("EM") conductors within the Diorite Hill Intrusive Complex ("Diorite Hill"), which are considered prospective for magmatic intrusive style nickel-copper-PGE mineralisation. The conductors were identified in a ground based moving loop EM ("MLEM") survey in 2021 and refined with a follow-up fixed loop EM (FLEM) survey in early 2022. Geophysical surveys and drilling of Diorite Hill represent stage one of the Company's exploration strategy for East Laverton. The next stage will target approximately 17km of ultramafic stratigraphy along the Granite Well and Rotorua trends, which are considered prospective for Kambalda style komatiite host nickel mineralisation. EM surveys covering prospective geology are planned for early-2023. Despite the presence of anomalous nickel in historic gold-focussed drilling, neither Diorite Hill nor the Granite Well trends have been previously targeted for nickel exploration. The Rotorua trend remains virtually undrilled to date. The Diorite Hill Intrusive Complex covers an area of approximately 110km² and consists of acumulate rock sequence of interlayered peridotites, pyroxenites, gabbros and anorthosite up to 7km thick. The intrusion is considered prospective for several styles of nickel-copper-PGE mineralisation, including contact style (i.e. Chalice Mines' Julimar deposit), conduit style (i.e. IGO Group's Nova-Bollinger deposit) and reef style (i.e. Merensky Reef in South Africa). There is very little outcrop exposure at Diorite Hill, so geological interpretation is largely derived from either geophysics or drilling. The vast majority of historic drilling is either shallow rotary air blast ("RAB") or aircore ("AC") targeting gold and/or PGEs, with only five diamond drill holes drilled to date. Ground based EM surveys conducted by GSN in 2021-2022 identified two conductive targets within the Granite Hill complex. The first conductor, L076, is located on or near the southern boundary the intrusion in a position considered favourable for contact or conduit style sulphide mineralisation. This conductor will be drilled with a diamond tailed RC hole to a downhole depth of approximately 600m. The second conductor, L124, is more discrete and interpreted to be on the basal contact of an ultramafic unit, which looks to be the lowermost unit within a sequence of layered intrusive stratigraphy. L124 is considered prospect for reef style sulphide mineralsiation. Shallow drill holes within the vicinity of this ultramafic contact have intercepted anomalous nickel as well as anomalous platinum and palladium (including 4m at 0.45% Ni in RAB hole DRA0004 and 0.5m at 153ppm Pd & 10ppb Pt in diamond hole DIORCDD121). Diamond hole DIORCDD123 intercepted 6.2m at 1.8% Ni from 46.8m within the oxide zone proximal to conductor L124. The East Laverton Nickel Project also contains approximately 17km of virtually unexplored ultramafic stratigraphy along the Granite Well and Rotorua trends. These are considered prospective for Kambalda style komatiite hosted nickel mineralisation. The Granite Well trend comprises of 10km of interpreted komatiitic ultramafic stratigraphy immediately west of the Diorite Hill intrusion, of which ~3km of strike is within GSN's tenure. Limited exploration has targeted Granite Well, however hole 94GWR245 on a neighbouring tenement to the north intercepted anomalous and coincident copper-nickel sulphides (20m @ 0.28% Cu, 0.11% Ni from 12m, including 4m @ 0.34% Cu, 0.16% Ni). In addition, multiple holes along this trend have nickel values above 0.2% with no drilling on the 3km portion of GSN's tenure. The Rotorua ultramafic trend consists of a 14km long ultramafic sequence extending south from the Diorite Hill intrusion. No historical nickel focussed exploration has been conducted over Rotorua, however limited shallow gold focussed AC drilling on the western margin of the ultramafic stratigraphy showed anomalous nickel (0.2-0.3% Ni) in base of holes samples. Drillhole RRLBVAC054 was also assayed for Platinum and Palladium with a peak value of 115ppb Pd+Pt. The presence of komatiitic spinifex textures were also noted in base of hole logging.

Great Southern Mining Limited Provides Exploration Update At Its Duketon Gold Project Great Southern Mining Limited announced an exploration update at its Duketon Gold Project, located 60km north of Laverton, Western Australia. In preparation for the next round of drilling, which is due to commence in late 2022 to early 2023, the Company has completed further targeting work proximal to known gold mineralisation within the Southern Star, Amy Clark and Golden Boulder prospect areas. Soil geochemical surveys have defined new targets along strike to the south of the Southern Star prospect and extended previously defined gold anomalism at the Amy Clarke prospect by a further 1.4km to 5km. Field mapping and rock chip sampling at the Golden Boulder prospect has defined at least three trends of historic gold workings with intense alteration noted over an area >3km in length and 500m wide. This area has had very limited historic drilling but will likely become a key focus for GSN's 2023 drilling programs. Southern Star sits on a well-endowed gold trend that hosts RRL's Rosemont and Ben Hur deposits (>1Moz and >350koz respectively). Ben Hur, which is located just 4km north of Southern Star, is due to be developed in RRL's current mine schedule. Mineralisation defined to date at Southern Star is open along strike and at depth with the potential to expand mineralisation into a sizeable mineral resource considered highly probable. Best results from the Company's drilling to date include: 69m @ 1.1 g/t Au from 39m, including a higher-grade core of 10m @ 3.5g/t Au including 2m @ 12.0g/t Au in 22SSRC00061; 59m @ 2.1 g/t Au incl. 9m @ 4.5 g/t Au and 16m @ 3.2 g/t Au from 53m in 21SSRC00092; 68m @ 1.9 g/t Au from 61m, including 4m @ 15.3 g/t Au from 89m and 5m @ 7.0 g/t Au from 114m in 21SSRC0036; 46m @ 1.2 g/t Au incl. 11m @ 3.4 g/t Au from 40m in 21SSRC00011; 7m @ 13.9 g/t Au incl. 1m @ 91.7g/t Au from 123m in 21SSRC0017; 17m @ 7.0 g/t Au from 111m incl. 2m @ 56.7g/t Au in 21SSRC0039. Extensive soil surveys have now been completed both north and south of Southern Star over the favorable quartz dolerite host rock with the objective of delineating drill targets along strike beyond the already defined 1km long zone of gold mineralisation. Southern Star southern soil results: Results in this announcement relate to a 497-sample soil program completed along strike to the south of Southern Star. Samples were taken on a 100m wide line spacing, 25m apart over a 4km strike of the prospective quartz dolerite geology. Assay results indicate a strong 700m long gold in soil anomaly in the southern portion of the survey area with a peak gold assay of 158 ppb. Other key pathfinder elements, including arsenic and antimony, form a very coherent trend over a 1.7km strike, which also correlates with the position of the favorable sheared quartz dolerite geology. This rock type is interpreted to be the primary host of high-grade mineralisation at Southern Star. Sulphur values are also of interest and have been used as an effective tool in ranking and identifying targets due to the high sulphide content of Duketon gold mineralsiation. High-grade mineralisation at Southern Star is associated with strong to intense quartz-albite-carbonate ± sericite alteration, quartz veining and disseminated sulphides (pyrite/pyrrhotite >3%). An area of highly anomalous sulphur (+0.1%) was noted around the core of the aforementioned high arsenic-antimony trend. The correlation of favorable soil geochemistry overlying the favorable quartz dolerite unit forms a compelling drill target in an area that has seen little to no historical drilling. Next steps: The Company is planning follow up reverse circulation (RC) drill programs in late 2022 to early 2023 to test newly identified geochemical targets along strike from the main mineralised zone of Southern Star. This includes the four targets previously identified along strike to the north. RC drilling is also planned to test depth extensions to known mineralisation at Southern Star. Amy Clarke Update: A maiden aircore drill program was completed in early 2022, which included a best intercept of 5m @ 8.2 g/t Au, including 1m @ 33.5 g/t Au from 33m in hole 21ACAC147. This hole was located at the southern limit of a previously defined soil anomaly, which prompted GSN to extend the soil geochemical survey further south. Assays have now been received for this extensional survey which consisted of 298 sites undertaken on a 100m wide line spacing, 50m apart over a prospective strike of ~1.8km. Results show the Amy Clarke gold-in-soil anomaly extending by a further 1.4km to the south, with the gold anomalism now defined over a 5km strike length. The scale of this anomaly bodes well for a large underlying mineralised gold system at Amy Clarke. Recent Insider Transactions • Nov 03

Great Southern Mining Limited Provides an Update on Duketon Gold Project 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.

Great Southern Mining Limited, Annual General Meeting, Oct 19, 2022 Great Southern Mining Limited, Annual General Meeting, Oct 19, 2022. Announcement • Jul 06
Great Southern Mining Limited Announces Exploration Update At the Duketon Gold Project Great Southern Mining Limited announced that it shares the Duketon Greenstone Belt with gold producer Regis Resources Limited, which has been successful in the identification of +8Moz of gold resources. Most of these deposits reside on major well understood shear zones. GSN's 250km of tenure in the Duketon Greenstone Belt includes significant portions of these shear zones. As high priority target corridors, GSN has aggressively begun to explore these well understood trends. It is interpreted that all three mineralised corridors continue into the company's tenure with: 8km of the Erlistoun Trend; 7km of the Garden Well Trend; 11km of the Rosemont-Ben Hur Trend. Upcoming exploration activities: The Company is designing multi-phase exploration programs at the Duketon Gold Project to explore these well understood shear zones hosting the bulk of mineral deposits in the Duketon Belt. These programs will see a combination of extensive multielement soils and geochemical programs in order to provide additional targets and aid in the design of further extensive slim-line reverse circulation(RC) and deeper RC drilling. Following the exceptional drilling results at Southern Star (announced 28/6/22) the exploration team is designing targeted programs aimed at known mineralisation zones with geochemical programs over the extensional zones being undertaken to delineate further follow up targets. A slimline RC program at the Amy Clarke Prospect is being designed, noting that previous results have delineated a kilometer- scale anomalous gold trend with standout intersection of 5m @ 8.2 g/t Au including 1m @ 33.5 g/t Au from 33m in 21ACAC0147; Further multielement soil analysis to be undertaken at Amy Clarke and the newly emerging Golden Boulder Prospect. This is part of an overarching strategy to discover and to grow Mineral Resources at the Duketon Project. Much of the mineralised trends, particularly at the Amy Clarke Prospect, has not been the subject of significant drill testing. Like Southern Star, the exploration along the trend by previous explorers appears to be shallow and ineffective, therein providing significant exploration upside for the Company.

Great Southern Mining Limited Announces Recent Results from Its Reverse Circulation (Rc) Drill Program At Its Southern Star Gold Deposit Great Southern Mining Limited announced recent results from its Reverse Circulation (RC) drill program at its Southern Star Gold Deposit (Southern Star), part of the 100% owned Duketon Gold Project, located 45km north of Laverton, Western Australia. Drilling at Southern Star has again reported exceptional gold grades of significant thicknesses. These results build on previous drill campaigns which have also have been highly successful including the following: 17m @ 7.0 g/t Au from 111m incl. 2m @ 56.7g/t Au in 21SSRC0039. 59m @ 2.1 g/t Au incl. 9m @ 4.5 g/t Au and 16m @ 3.2 g/t Au from 53m in 21SSRC0009. 68m @ 1.9 g/t Au incl 4m @ 15.3 g/t Au and 5m @ 7.0 g/t Au from 61m in 21SSRC0036. 46m @ 1.2 g/t Au incl. 11m @ 3.4 g/t Au from 40m in 21SSRC00011. 7m @ 13.9 g/t Au incl. 1m @ 91.7g/t Au from 123m in 21SSRC0017. 27m @ 1.5 g/t Au incl. 6m @ 5.0 g/t Au from 77m in 21SSRC0015. The recent drilling results reported in this announcement focused on an area ineffectively explored, between two high grade zones. The outstanding intercepts noted now link the two zones of high-grade gold and enhance the zone of gold mineralisation already defined. These robust sections of gold mineralisation are expected to have a positive impact on the resource potential of the project, as mineralisation now joins together in a thick, continuous zone of over 600m. Drill holes in the new zone have delivered significant gold intercepts including 13m @ 1.3 g/t Au from 49m including 2m @ 6.9 g/t Au and 3m @ 3.5g/t Au from 78m in 22SSRC0005 and 69m @ 1.1 g/t Au from 39m including a higher-grade core of 10m @ 3.5 g/t Au including 2m @ 12.0 g/t Au in 22SSRC0006. This zone remains open at depth and will be a focal point for follow-up drilling. The new drilling suggests a coherent panel of mineralisation with historic drillhole locations in this area being estimates only given their vintage. The quartz dolerite is the primary host to high-grade mineralisation at Southern Star. Most gold bearing veinsare parallel to the shearing and the stratigraphy (NNW-SSE) and are dipping sub-vertically. High-grade mineralisation is associated with strong to intense quartz-albite-carbonate ± sericite alteration, quartz veining and disseminated sulphides (pyrite/pyrrhotite >3%). Proximal to mineralisation, the quartz dolerite becomes medium to coarse grained, displaying a granophyric texture due to being dominated by quartz-albite-carbonate ±sericite alteration. A total of 4,931m of RC drilling was completed from this recent program and builds on the total of over 11,000m which now has been drilled by GSN since acquiring the project in February 2021. The combination of this drilling has demonstrated the mineralisation is coherent and potential for resource development at Southern Star is now emerging. GSN's 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 the company's tenure with: 8km of the Erlistoun Trend; 7km of the Garden Well Trend; 11km 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. 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. Exploration along the trend by previous explorers appears to be limited to shallow 80m wide spaced RAB and aircore drilling, the target quartz dolerite unit is known to pinch and swell, resulting in the true thickness of the unit ranging from 5-50m in places making previous exploration Part of the Company's recent RC program at Southern Star began to test the trend to the south. Low-level gold anomalism was identified in multiple drillholes. When distal to gold mineralisation, the quartz dolerite is characterised by blue quartz and plagioclase phenocrysts in a chlorite ±carbonate ±magnetite matrix. Blue quartz and plagioclase phenocrysts were observed in multiple holes suggesting the recent drilling was successful in mapping out the distal mineralisation within the quartz dolerite unit. Multi-element composite sampling was undertaken on the recent drill campaign with the intention to map out the albite-carbonate ±sericite alteration to vector in on the high-grade mineralisation. Results of the multielement analysis is still pending. Announcement • Jun 15
Great Southern Mining Limited Announces Drilling to Commence at the East Laverton Nickel Project Great Southern Mining Limited announced that following the Company's success in being awarded the Exploration Incentive Scheme (EIS) grant in May 2022, the Company is now in the position to drill test the East Laverton Nickel Project. Work has continued on the refinement of the location and dip of conductors L076 and L124. The conductors have now been modelled in 3D, with the drill program designed to test the bedrock conductor at L076 with a 600m drill hole (RC with diamond tail) planned. The conductor has been modelled at 2km x 1km in length. Continued refinement of conductor L124 has also noted the conductor is located proximal to a magnetic source within the interpreted intrusive and modelled at 300m X 300m. This isolated conductor, identified in the centre of the Diorite Hill intrusion, is considered prospective for platinum-group elements (PGE) enrichment. The drill program has been planned with the conductor to be tested with a number of RC holes. Next Steps: Additional work is being undertaken to identify additional conductors using the same modern exploration techniques which yielded the compelling conductors over the Diorite Hill intrusion. The Company is also looking to undertake a similar style moving loop electromagnetic survey, designed by geological consultants Newexco Exploration Pty Ltd, on the Rotorua and Curra Komatiite units. These units have had very little nickel exploration historically with komatiite style mineralisation being the focus for GSN. The survey is likely to take place following the completion of the drill program. Remarkably, little exploration has previously occurred over the Rotorua Complex. Limited RAB lines have been drilled by BHP-Utah in 1998 and Newmont Australia in 2005, however the focus was exclusively on gold mineralisation. Announcement • May 12
Great Southern Mining Limited Provides Update on Exploration Activities Great Southern Mining Limited updated the market on its exploration activities. The current Reverse Circulation (RC) drilling program at Southern Star is progressing well with over 50% of planned metres completed. The drilling was designed to intersect the quartz dolerite unit along strike, as this is the host of the gold mineralisation at Southern Star. Drilling to date has intersected the target unit on multiple lines of drilling and assay results are expected to start to be received this month. Application of a Mining Lease over the larger project area at Southern Star has been successful with the Company pleased to advise that the Mining Lease has been granted by the Department of Mines, Industry, Regulation and Safety (DMIRS). The Mining Lease has an initial term of 21 years. The Mining Lease is another critical step for the development of Southern Star and is necessary for any future mining activities. The lease has been designed to provide access to the Bandya Road which is the main public road which runs through the tenement and continues through to the Amy Clarke prospect. This provides potential treatment options including toll treatment, road train access and other potential processing options. The exploration team in north Queensland has continued to consolidate the considerable amount of exploration data obtained following the extensive reviews of the current target prospects following last year's field activities. As the late wet season ends, the 2022 field season is set to commence, with site inspections and field validation exercises due to take place in the coming weeks at the Mt Dillon, Fish Creek and Edinburgh Castle prospects.

Great Southern Mining Limited Announces Large Scale Mineralised System Identified At Amy Clarke Great Southern Mining Limited announced the 1m split and bottom of hole multi-element results of the aircore drill program conducted in late 2021 at one of its regional targets, Amy Clarke, in the Duketon Gold Project, located 60km north of Laverton, Western Australia. A 172-hole aircore program for 5,586m was completed in December last year at the Amy Clarke Prospect. The results of this announcement relate to the 1m samples taken from the previously identified anomalous 4m composite samples. In conjunction, a separate, bottom of hole sample of each drillhole was also taken for multielement analysis which has been utilised to map the newly identified mineralised system. The drilling was regarded as highly successful and multiple holes encountered gold anomalism that forms a coherent gold trend. The trend can be traced north-south through the prospect and every drill line, with the exception of one, intersected gold anomalism. This newly defined gold trend also correlates well with the previously identified gold in soil trend. A standout assay result of 5m @ 8.2 g/t Au including 1m @ 33.5 g/t Au from 33m in 21ACAC0147; 1m @ 1.2 g/t Au from 2m in 21ACAC007; 2m @ 0.6 g/t Au from 16m, 1m @ 2.5 g/t Au from 24m and 1m @ 0.7 g/t Au from 32m in 21ACAC022; 1m @ 3.95 g/t Au from 47m in 21ACAC029; 3m @ 1.5 g/t Au from 1m in 21ACAC055; 1m @ 0.5 g/t Au from 1m, 1m @ 0.66 g/t Au from 12m, 2m @ 0.5 g/t Au from 20m and 1m @ 1.3 g/t Au from 35m in 21ACAC065; 2m @ 1.1 g/t Au from 4m and 1m @ 0.7 g/t Au from 21m in 21ACAC066; 1m @ 0.5 g/t Au from 27m and 2m @ 0.4 g/t Au from 35m and 1m @ 1.7 g/t Au in 21ACAC077; 1m @ 0.6 g/t Au from 18m and 1m @ 0.3 g/t Au from 35m in 21ACAC084; 2m @ 0.7 g/t Au from 20m in 21ACAC104; 1m @ 0.7 g/t Au from 58m in 21ACAC136; and 1m @ 1.7 g/t Au from 20m and 1m @ 0.8 g/t Au from 25m in 21ACAC172. The standout intersection of 5m @ 8.2 g/t Au including 1m @ 33.5 g/t Au from 33m in 21ACAC147 is significant in isolation but also as it forms part of a much larger anomaly which has excellent correlation with kilometre-scale pathfinder elements. The recent bottom of hole analysis clearly maps out the mineralised system with several elements forming distinct trends that corelate with the high-grade gold intersections. Arsenic is mapping out the mineralised shear zone that can be traced for the length of the drilling to date which extends for nearly 4km, with the current extent of drilling remaining open, particularly in the south.

Great Southern Mining Limited Announces Collaborative Exploration Incentive Grant Awarded in QLD Great Southern Mining Limited has been awarded a Collaborative Exploration Initiative (CEI) grant from the Queensland Government for a proposed Calculated Mineralogy FTIR and XRF program over a number of targets at its 100% owned Edinburgh Park Project in north Queensland. Highlights: Grant awarded for up to $100,000 of program costs. Proposed program includes analysis of rock, soil and historical drill core samples using FTIR (Fourier-Transform Infrared Spectroscopy) with XRF (X-Ray Fluorescence) with AI interpretation. Program covers 5 prospects delineated to date including Molongle, Fish Creek, Leichhardt Creek, Edinburgh Park and Mt Dillon. This complete analysis opens the district to new economy minerals not previously the focus of historical exploration. Target minerals include known anomalism existing at the nearby Mt Carlton Gold Mine. The Company's tenements cover a sequence of Early Permian Lizzie Creek Volcanics and Permo- Carboniferous intrusives within the northern end of the Permian Bowen Basin that are favourable for the discovery of: Low Sulfidation and High Sulfidation epithermal gold-silver-trace metal deposits within major persistent fault zones and suitable Permian-Triassic rhyolitic and andesitic volcanic host lithologies; and Intrusive Related (IRGS) and Porphyry-style deposits within the underlying basement granite, adamellite, syenite, and granodiorite. At the target scale, the geological lithologies vary from very fine grained, almost aphanitic tuffs, grading upwards to coarse volcanic breccias. Some intrusive rhyolites exhibit layering, in some cases they are presenting parallel flow bands and other instances are a convoluted and contorted flow banding. Some porphyritic rhyolites also have been mapped in the area. All of these lithologies have been assigned to the Lizzie Creek Volcanics, a suit of acid to meso-silicic volcanic rocks. Syenite, monzonite, andesite and diorite dykes crosscut the entire volcanic sequence. the mapped geology at the Fish Creek prospect. This mapping illustrates a series of northwest trending zones of silicification that have been identified. These are generally aligned with a regional suite of lineaments that correlate with a swarm of andesitic dikes. The zones of silicification within the volcanic sequences are generally considered to be a favourable alteration indicator for possible mineralization. Alteration associated with epithermal deposits, such as Mt Carlton, includes silicic cores with haloes of advanced argillic minerals, such as alunite, dickite, kaolinite, pyrophyllite, diaspore, and pyrite. The Hyperspectral survey flown in 2019 and co-funded by Evolution Mining Limited was the first data set that recognised the advanced argillic alteration assemblage at Fish Creek. GSN has been using this association as target mineralogies for regional hyperspectral mapping, and local hand specimen spectral analysis as tools, along with geology and magnetics surveys, to assist identification and delineation of prospectivity for epithermal, high-sulphide epithermal, and porphyry styles of gold and copper mineralisation. the alteration spectra mapping that has been completed over the Fish Creek prospect geological mapping. Similar spectra associations have also been identified at additional targets delineated from the Hyperspectral survey at Molongle, Mt Dillon, Leichhardt Creek and Edinburgh Castle prospects. . The CEI funding of $100,000 shall support the collection and analysis of rock chip, soil, and drill core samples for detailed Short Wave Infra-Red (SWIR) analyses to assist the further delineation and persistence of these alteration mineralogies from both surface and sub-surface sampling programs. A drill proposal has been prepared for the Fish Creek prospect to complement the previous drilling proposal for the Molongle prospect. Announcement • Feb 16
Great Southern Mining Limited Announces Results from Diamond Drilling Confirms Gold System at Southern Star Great Southern Mining Limited announce results from its maiden Diamond Drilling program from the Southern Star Gold Deposit at its 100% owned Duketon Gold Project located 45km north of Laverton, Western Australia. A two hole 319.5m DD program has been completed at Southern Star. The purpose of this drilling was to obtain further insight into the gold mineralisation at Southern Star, which is open to the north, south and at depth. The two diamond holes were drilled 580m apart at opposite ends of the current known mineralisation, with the intention to examine the structural orientation of quartz veining, folding and foliation at the current extents of mineralisation. Gold mineralisation at Southern Star is hosted in an east-dipping 345°- trending quartz-dolerite unit which is approximately 80m wide. The drilling was designed to target the footwall of the quartz dolerite unit as this is where the primary lode is persistent and of high-grade based on assessment to date. The high-grade mineralisation can be traced for over 700m of strike length and is open in all directions. Major shearing runs the length of the deposit with gold mineralisation being associated with quartz veining and sulphides within the fractionated dolerite unit, pervasive foliation was observed in both diamond holes and strikes 345° which matches the regional strike and further supports the relationship between Ben Hur and Southern Star. The objective of the diamond drilling program was to build on the geological understanding of the deposit including the orientation of the structures controlling the gold mineralisation. Diamond hole 21SSDD001 intersected a wide zone of multi-phased quartz veining from 56.6m to 80m. High- grade mineralisation was intersected within this zone of 20m @ 1.7 g/t Au from 62m including 1.6m @ 13.2 g/t Au from 76.6m. The high-grade interval corelates with previous recent Reverse Circulation drilling of 68m @ 1.9 g/t Au from 61m incl 4m @ 15.3 g/t Au from 89m and 5m @ 7.0 g/t Au from 114m in 21SSRC0036. Intense sequence of alteration assemblages was observed, logging of alteration of the core took place and intense albite alteration with hydrothermal veining corelates well with the area of high-grade gold intervals. Reviewing pathfinder data within the Leapfrog model, Bismuth, a known magmatic pathfinder, appears to correlate well with the zone of logged albite alteration. Arsenic, a known basin/metamorphic pathfinder, appears to correlate well with the sericite/brown mica alteration, which was observed deeper downhole which corelates to a secondary zone of gold mineralisation with 8.3m @ 0.63 g/t Au from 110m intersected. This Arsenic-sericite zone sits adjacent to the albite-bismuth zone. This new understanding of alteration assemblages and pathfinder elements will be key in vectoring in on the high-grade mineralisation at Southern Star. The second diamond hole intersected similar alteration assemblages although notably not as intense, a wide zone of quartz veining was also absent, selective sampling of the second hole from 114m to 131m was undertaken where albite alteration and a quartz veining was intersected. Although only limited intercepts of significant gold were intersected, it is interpreted to be proximal to the mineralised zone due to the similarities in the alteration assemblages. The remainder of the core is currently being cut and multi-element analysis is been undertaken on both diamond holes. Announcement • Feb 09
Great Southern Mining Limited Announces Infill Flem Survey Underway At East Laverton Nickel Project Great Southern Mining Limited announced that an infill Fixed-Loop Electro-Magnetic (FLEM) survey is underway at the Company's 100%-owned East LavertonNickel Project in Western Australia. The 2021 Moving-Loop Electro-Magnetic (MLEM) survey was the first of its kind over the Diorite Hill magmatic complex. The MLEM survey results allowed 3 bedrock conductors to be modelled by leading exploration and geophysical consultants Newexco Pty Ltd. A closer spaced FLEM survey has now been designed by Newexco. The FLEM survey is underway over the 2 conductors (76 and 124) and will aim to refine the strike and dip of the conductors to improve the accuracy of planned drill testing. The results of the FLEM survey are expected later this month. A heritage survey to facilitate drill testing of the conductors has been booked with the Traditional Owners, also for later this month. The East Laverton Nickel Project is dominated by the Diorite Hill magmatic complex (Diorite Hill). Diorite Hill covers an area of approximately 110km2 and consists of a thick (7 km) cumulate rock sequence of interlayered peridotites, pyroxenites, gabbros and anorthosites. The southern and eastern part of the complex is contained within the project area. Diorite Hill intruded a greenstone volcanic rock sequence indicated by the presence of non-cumulate mafic/ultramafic hornfels xenoliths within the complex. Diorite Hill is commonly covered by shallow modern aeolian sands that have hampered previous exploration. Diorite Hill is abutted to the south by the Rotorua Komatiite, a 10km by 1.5km extrusive ultramafic. The Curara Komatiite is further to the east. Komatiites flows have been the main source of developed nickel-sulfide mines in WA and have been explored extensively since the late 1960's. Due to their well understood geochemistry, formation, and high-grade sulfide enrichment process within defined channels, most of the studies and exploration programs in WA have focused on discovering this style of mineralisation. The Kambalda-Kalgoorlie-Leinster-Laverton Goldfields Region has been the main focus for komatiite exploration, with limited potential existing outside this region. Greenfields discoveries of komatiite nickel have reduced in recent years in the Goldfields Region and it's only deep brownfields exploration that is delivering new nickel deposits.

Great Southern Mining Limited Announces the Results of the Aircore Drill Program Conducted at One of its Regional Targets at the Duketon Gold Project Named Amy Clarke, Located 60Km North of Laverton, Western Australia Great Southern Mining Limited announced the results of the aircore drill program conducted at one of its regional targets at the Duketon Gold Project named Amy Clarke, located 60km north of Laverton, Western Australia. A 172-hole aircore program for 5,586m was completed during December last year at the Amy Clarke Prospect. The objective of the drill program was to assess the gold potential of the kilometre-scale gold in soil anomalies delineated in September last year. The drilling was regarded as highly successful and multiple holes encountered gold anomalism that form a coherent gold trend. The trend can be traced north-south through the prospect and every drill line, bar one, intersected gold anomalism. This newly defined gold trend also corelates well with the previously identified gold in soil trend. Significant assay results include: A standout assay result of 8m @ 6.73 g/t Au from 32m including 4m @ 12.5 g/t Au in 21ACAC147; 4m @ 0.55 g/t Au from surface in 21ACAC007; 4m @ 0.52 g/t Au from 44m in 21ACAC029; 4m @ 2.13 g/t Au from surface in 21ACAC038; 4m @ 1.23 g/t Au from surface in 21ACAC055; 8m @ 0.31 g/t Au from 32m in 21ACAC065; 4m @ 0.57 g/t Au from 32m in 21ACAC078; and 4m @ 0.50 g/t Au from 16m in 21ACAC085. The standout intersection of 8m @ 6.73 g/t Au from 32m including 4m @ 12.5 g/t Au in 21ACAC147 is significant on multiple lines of evidence. Firstly, it forms part of a much larger anomaly which has excellent correlation with kilometer-scale gold in soil anomaly. The intersection is the first high-grade gold discovered in the Amy Clarke area, with grades inline with those found in gold deposits throughout the Goldfields, demonstrating that Amy Clarke may host a gold deposit of economic significance. The position of the high-grade intersection is also highly encouraging as it sits 32m to 40m downhole within a sheared basalt with quartz veining in fresh rock below the weathered zone. A thin veneer (0.5- 10m) of cover is typical throughout the prospect area and the majority of gold intersections are within highly sheared mafic bedrock. Hole 21ACAC147 was one of only 24 holes of the program drilled deeper than 40m (maximum depth 60m) and highlights that deeper drilling is required at Amy Clarke. The positioning of the gold anomalies is of particular interest as the anomalies reside in a magnetic low feature housed on each flank by distinct magnetic high features which are conspicuous landforms of Banded Iron Formation (BIF) ridges in the area. The magnetic low channel can be traced north to the Erlistoun gold deposit and is interpreted to be the same position along strike that host the 322 koz @ 1.9g/t Erlistoun deposit owned by Regis Resources Limited. Cross cutting secondary structures have been interpreted, represented as breaks in the magnetic high features on the total magnetic intensity data. These north-eastern structures are believed to act as fluid traps which aids in localising mineralisation and commonly occur proximal to large gold deposits in the Duketon Belt. Two cross cutting features have been identified at Amy Clarke and have a proximal relationship to the gold in soil anomalies, with the southern structure in close proximity to the new high- grade intersection. Bismuth in soils showed excellent correlation with the gold in soil anomaly with concentration towards the centre `hotspots'. Aircore drilling has confirmed that bismuth is a good proxy for gold mineralisation as the main mineralised trend and the high-grade intersection (4m @ 12.5 g/t Au in 21ACAC147) sit directly in line with the bismuth anomaly. Gold association with pathfinder elements such as bismuth indicate that the source of the anomalies is less likely to be transported as these elements are less mobile within the weathering regime.

Great Southern Mining Limited Announces Drilling Commences At Amy Clarke Gold Prospect Great Southern Mining Limited announced that drilling has commenced at the Amy Clarke Gold Prospect, within the Duketon Gold Project, located 60km north ofLaverton, Western Australia. First-pass air-core drilling has commenced at the Amy Clarke Gold Prospect, part of the Company's 100% owned Duketon Gold Project located 60 km north of Laverton, Western Australia. Approximately 200 holes will be drilled to blade refusal for up to 8,000m of drilling to test gold anomalism, typically above 8 ppb Au and up to 690 ppb Au, extending for at least 4 kilometres in strike length. This is the first of several regional first-pass air-core drilling programs anticipated across GSN's extensive 450 km2 Duketon Gold Project as part of ongoing exploration plans. Announcement • Sep 24
Significant Gold Intersected at Duketon Regional Targets Great Southern Mining Limited announced the results of a 4,754m Reverse Circulation (RC) program at four regional targets in the Duketon Belt named One Weight Wonder, Golden Boulder, Ogilvies, and Erlistoun located 60km north of Laverton, Western Australia. Following the acquisition of E38/3518 in July 2020 and E35/3501 in February 2021, Company geologists collated an expansive regional dataset incorporating more than 12,000 drill holes and 24,000 soil samples. The exploration team then set about analyzing and ranking the targets to provide a clear strategic exploration pipeline of regional targets which would complement the focused drill program at Southern Star. High grade intersections correlate to a chert rich lithology within a sediment package which is similar to that seen at Garden Well (Figure 2). These significant intersections also corelate to the orientation of the regional mineralised structures (~310°) that hosts all major deposits in the Duketon Belt. The drilling successfully intersected bedrock mineralisation at four separate locations indicating that mineralisation is primary in nature and open at depth and along strike. Further assessment of the results is underway and a selection of samples will be sent for multi-element analysis to build on the understanding of mineralisation pathfinders. Initial results are very encouraging considering the early stage of exploration and further work will be designed following the multi-element analysis. Very limited drilling has been completed at One Weight Wonder and the mineralisation tends to be widening to the south where no drilling has taken place along the mineralised chert contact. The Golden Boulder target was identified by a 100ppm down hole arsenic anomaly and 100ppb gold anomaly that strikes directly adjacent to the regional mineralised structure. Gold mineralisation is interpreted to extend south along-strike from a set of old workings into GSN tenements where it is obscured by cover. The Ogilvie's target is defined by historical drilling of 41 shallow holes at Ogilvie's in 1986 with 14 holes intersecting plus 1.0 g/t gold intersections, with higher grades of 4m @ 5.0 g/t Au (OL 11) and 2m @ 4.9 g/t Au (OL 06) encountered.

Great Southern Mining Limited Announces Update on Exploration Activities at the 100%-Owned Edinburgh Park Project in North Queensland Great Southern Mining Limited provided an update on exploration activities at the Company's 100%-owned Edinburgh Park Project in north Queensland, following recent additional interpretation of soil geochemistry data obtained from the Leichhardt Creek Survey area. Extended Soil Surveys: The Company has received results from geochemical survey work, comprising over 1,554 soil samples and 23 rock chip samples, recently completed over a 10 km2 area north of Beaks Mountain (Leichhardt Creek Survey area). The Leichhart Creek Survey area is coincident with one of nineteen anomalies identified from the hyperspectral survey conducted in 2019 and co-funded by Evolution Mining Limited. The geochemical mapping program extended and refined the earlier 2020 survey which had not closed off gold anomalism. The survey area was therefore extended to the south and west on a wide spaced (100m x 100m) grid. The survey area was also infilled to a closer spacing (50m x 50m) in the Leichhart West - Green Ant location where geological observations heightened the prospectivity. These three soil surveys were designed to test the gold-copper-molybdenum metal associations and aimed to identify metal zonation patterns consistent with large IRGS. Geochemical Results: The recent geochemical analysis, including the three soil surveys, recognised compelling circular metal zonation consistent with large IRGS. The anomalies were enhanced by levelling of the data to the key elemental ratios known to be associated with the style of mineralisation being targeted. This levelling of the data also reduces the effects of weathering, weak leaching, or mechanical dispersion from the data. The geostatistical analysis shows evidence of at least two major mineralised systems with IRGS affinity operating in the area and several minor satellite occurrences clustered in the surrounding area. One of the main systems, Leichhardt West - Green Ant, situated on the south-west corner of the soil grid, is coincident with geological evidence of alteration and mineralisation consistent with an IRGS style. This target has been advanced to target definition stage. Mapping and sampling will continue until key criteriums are identified to refine down to specific drilling targets. The second main system is at Beaks Flats where textbook circular metal zonation has been identified in the soils. The Core Zone is the area shown in yellow associated with gold (up to 130 ppb), arsenic (up to 12ppm), antimony (up to 8 ppm), and bismuth (up to 3.5 ppm) anomalism. The Proximal Zone is the area shown in green associated with copper (up to 600 ppm) and molybdenum (up to 12 ppm) anomalism, and a low gold response. The Distal Zone is the area shown in grey associated with zinc (up to 1,100 ppm) and lead (up to 360 ppm). The geochemical anomalism shows clear temperature-dependent metal zones from lower temperature (outwards) to higher temperature (inwards) in both systems. Geological Evidence: The geochemical anomalies are coincident with independent geological evidence consistent with IRGS in some areas and epithermal high sulphidation deposit styles in other areas. This evidence includes high- grade copper, gold and silver rock chips. Interestingly, the high-grade rock chips are located at the margins of the geochemical anomalies rather than at the newly identified core (Figure 1). This highlights the importance of methodically considering the overall geological and geochemical system, rather than individual mineralised outcrops. Megan Veins: Megan Veins is a set of doleritic dikes oriented NW - SE. Each of these dikes has a general width of 1 to 3 m and they can extend for up to 120 m. The host syenite is silicified and the doleritic dikes are affected by a quartz stockwork assaying up to 2 g/t gold. The rock samples from the dikes contain copper oxide minerals and returned values up to 4% copper. Announcement • Mar 13
Great Southern Mining Limited Provides Duketon Belt Exploration Update Great Southern Mining Limited announced that the Cox's Find Gold Project is a shear hosted orogenic gold deposit located in the Duketon Greenstone Belt, located 12kms along strike from Regis Resources' multi-million-ounce Garden Well deposit and associated 5Mtpa mill. The Cox's Find underground gold mine was operated by Western Mining Corporation's (WMC) for a short period between 1937 and 1942 producing approximately 77,000 ounces of gold at a reported head grade of ~22 g/t from a vein stope operation. GSN have been exploring the Cox's Find deposit since late 2019 and have successfully identified a high- grade ore panel that was missed by WMC with previously reported high grade results: 19CFRC002 - 8m at 9.43 g/t gold from 73m, including 1m at 44 g/t. 19CFRC004 - 2m at 36 g/t gold from 146m, including 1m at 68 g/t. 19CFRC009 - 5m at 14.54 g/t gold from 140m, including 2m at 28.85 g/t. 19CFRC011 - 6m at 7.90 g/t gold from 132m, including 1m at 35.9 g/t. 19CFRC013 - 5m at 31.23 g/t gold from 134m, including 1m at 143.0 g/t. 20CFRCD004 - 5m @ 80.0 g/t gold from 160m including 1m @ 404 g/t. 20CFRCD008 - 3.6m @ 8.03 g/t gold from 169m including 1m @ 27.5 g/t. Of these, four holes (20CFRC048-51) for 770m were allocated to test the south eastern down plunge target. Drillholes 20CFRC0048 and 20CFRC0050 intersected mineralisation with 15m @ 0.4 g/t Au including 1m @ 1.3 g/t Au from 175m (20CFRC0048) and 1m @ 0.3 g/t Au from 167m (20CFRC0050). Interpretation that the orientation of the high-grade shoot may be wrenching from their generally south-easterly plunge to the southern search space is still valid and targeting behind drill hole 20CFRC049 is now warranted.

Great Southern Mining Limited Announces Mon Ami High-Grade Gold Continues At Depth Great Southern Mining Limited announced Mon Ami High-Grade gold continues at depth. Mon Ami RC Drilling: Fourteen Reverse Circulation (RC) holes were drilled at Mon Ami for a total of 1,601m in January 2021. The objectives of the Mon Ami drilling program were two-fold. Firstly, to test for possible depth extensions analogous to the 176koz (at 22.8 g/t Au) Ida H deposit located 8km north of Mon Ami. Secondly, the program was aimed to define and extend near-surface, high-grade gold mineralization to the south, for incorporation into a targeted resource classification upgrade. Mon Ami Depth Extensions: Two deeper RC holes (21MARC009 and 10) were designed to test for depth extensions of the main lode at Mon Ami. The target gold mineralization is considered analogous to the 176koz (at 22.8g/t Au) Ida H underground gold mine, located 8km to the north of Mon Ami along the same Bandicoat shear zone. Both holes intersected gold mineralization within a broad zone of chlorite-sericite alteration. Gold is concentrated within quartz veining at the lithological contact of a metasedimentary sequence and a basalt unit within the regional scale Bandicoat Shear Zone. The long section of the Mon Ami deposit highlights the dominant northerly plunge to the high-grade mineralization, which this drilling aimed to extend. Both holes intersected significant mineralization and 21MARC010 was extended 30m past planned hole depth as chlorite-sericite alteration and quartz veining was pervasive. Extension of hole 21MARC010 resulted in a standout wide zone of mineralization of 10m at 2.7 g/t Au from 241m including 5m at 5.2 g/t Au and 21m at 1.0 g/t Au from 255m. 21MARC010 was a significant 100m step out, down plunge from previously identified high-grade mineralization in MLRC036 (2m at 27.5 g/t Au). The high-grade gold mineralization at Mon Ami is now known to extend for at least 500m and is open along strike and at depth. This hole is regarded as highly significant as it is the deepest hole drilled to date at Mon Ami, with alteration and mineralization widening at this location. The high-grade gold mineralization intersected in hole 21MARC010 is at 210m below the surface, 60m deeper than the current Inferred Mineral Resource of 1.1Mt at 1.7g/t Au for 59,000 ounces of gold, which is limited to 150m below surface. Mineralization is currently constrained only by drilling and demonstrates the potential for mineralization to persist further down plunge along strike. Near Surface Definition and Extension: Twelve shallower holes were drilled into the southern portion of the deposit seeking to define and extend near-surface gold mineralization. Coherent mineralization was intersected across all holes with better intersections including; 10m at 1.0 g/t Au from 18m and 8m at 1.1 from 47m in 21MARC001; 10m at 1.4 g/t Au from 51m in 21MARC002; 5m at 1.8 g/t Au from 55m in 21MARC003; 4m at 1.4 g/t Au from 12m in 21MARC005; 4m at 0.8 g/t Au from 33m in 21MARC006; 4m at 2.5 g/t Au from 120m in 21MARC007; 4m at 6.6 g/t Au from 8m including 2m at 11.6 g/t Au in 21MARC008.

Great Southern Mining Limited Announces That It Has Secured an Exclusive, Irrevocable Option over Three Large Exploration License Applications Around Its Cox's Find Gold Project in the Laverton Region of Western Australia Great Southern Mining Limited announced that it has secured an exclusive, irrevocable option over three large exploration license applications around its Cox's Find Gold Project in the Laverton region of Western Australia. Upon exercise of the option, GSN expects to substantially expand its land position in the Duketon Greenstone Belt from 47km2 to 459km2. The Golden Star Deposit is located 4km along strike to the south of the Ben Hur Deposit and 32km south of the Garden Well Mill, both owned by Regis Resources Limited. Duketon Mining Limited drilled the Golden Star Deposit in 2017-18, demonstrating over 600m of continuous mineralised strike length, open in all directions. Best drill intersections at Golden Star, previously reported by Duketon Mining Limited, 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. 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. High grades, up to 60g/t Au have been intersected plus several 50 gram-metre intersections and, in places, plus 90 gram-metre intersections. Mineralisation occurs within 4m of the surface in areas and high grades are seen throughout the mineralisation. Sulphides and some quartz veining have been identified north and south of this main zone of mineralisation. Announcement • Jan 06
Great Southern Mining Limited Announces Drilling Update on Mon Ami Gold Project Great Southern Mining Limited's 100%-owned Mon Ami Gold Project is located 17km south-east of Laverton in Western Australia. Historically the Laverton Goldfield has produced over 25 Moz of gold. Mon Ami has an Inferred Mineral Resource of 1.1Mt at 1.7g/t for 59,000 ounces of gold and favorable metallurgical recoveries averaging 95% in oxide and transitional mineralisation. GSN is progressing the necessary technical and environmental studies to facilitate a mining approval that contemplates processing at one of several nearby mills. The objectives of the Mon Ami drilling program are two-fold. Firstly, to define and extend near-surface, high-grade gold mineralisation for incorporation into a targeted resource upgrade. The drill results reported to the ASX on 12 August 2020 included several near-surface high-grade hits including 11m @ 7.9 g/t gold from 26m (including 4m @ 15.9g/t gold) in 20MARC011, and 4m @ 12.4 g/t gold from 80m in 20MARC003 (4m composite sample). Interpretation of the results has identified opportunities to extend these high-grade zones with shallow Reverse Circulation (RC) drilling, which is targeted to further improve the economics of a potential open pit development. Secondly, the program aims to test for possible depth extensions analogous to the 176koz (at 22.8g/t Au) Ida H deposit located 14km to the north of Mon Ami along the same regional shear zone. The long section of the Mon Ami deposit (Figure 3) reveals a dominant northerly plunge to the mineralisation, including a 2m @ 27.5 g/t Au intersection from 173m in MLRC036. There has been no drilling directly down plunge along this trend until now. In December 2020, 9 RC holes for 1,393m were drilled at Cox's Find and assay results are pending. A further 15 RC holes are planned to be drilled at Cox's Find later in January 2021 to continue testing the targets identified in the ASX announcement of 11 November 2020. Upon completion of the current Mon Ami drilling, the drill rig is planned to immediately return to Cox's Find to complete the committed drilling which totals 5,400m across both of GSN's Laverton gold projects.

The Cox's Find Gold Project (Cox's Find) is a shear hosted Archaean orogenic gold deposit located in the Duketon Greenstone Belt in the Laverton Gold District of WA, located along strike from, and within 15kms of, Regis Resources Limited's multi-million-ounce Garden Well Gold Mine (Figure 2). The historical Cox's Find Gold Mine was operated by Western Mining Corporation (WMC) for a short period between 1937 and 1942 producing approximately 77,000 ounces of gold at a reported head grade of ~22 g/t from a vein stope operation. The recent drill results at Cox's Find not only included several spectacular high-grade intersections of up to 5m @ 80.0 g/t Au from 160m including 1m @ 404 g/t Au, but also a highly significant 15m @ 1.01 g/t Au intercept from 167m in hole 20CFRC034. The significance of this intercept is that it opens up an entirely new search space immediately to the south of the high-grade unmined panel delineated by recent pectacular high-grade drill intersections (Figure 3). The thickness of the intercept may be indicative of a mineralised halo surrounding a nearby high-grade extension to the Cox's Find orebody. GSN believe that the Cox's Find orebody may be reoriented from its generally south-easterly plunge towards the southern search space due to wrenching associated with south trending shear zones. The program will include an initial six 190m deep Reverse Circulation (RC) holes to test this southern search space. The drilling program will also test the near-mine along-strike targets to the south of Cox's Find. Here the same lithology, folding, and faulting observed at Cox's Find is repeated. The drilling will continue over the next few months, aside from a 2-week break over Christmas. 5,400m of RC drilling is committed. As well as the Cox's Find targets, the drilling program will also test targets at Mon Ami identified in the ASX announcement of 13 November 2020 including near-surface, high-grade material to improve open pit development potential and deeper high-grade target analogous to the nearby Ida H high-grade underground mine.

Great Southern Mining Limited Announces Receipt of Eis Grant and Drilling Set to Commence Great Southern Mining Limited announced the approval of the first payment of AUD 109,000 relating to the co-funded drilling campaign at the company's Cox's Find Gold Project (Cox's Find) under the 2020 Exploration Incentive Scheme. The balance of the total grant of AUD 136,000 is anticipated early in 2021 upon acceptance of the final report. The drilling advanced the understanding of the structural controls on mineralisation at Cox's Find and included spectacular gold results previously announced to the market of up to 5m @ 80.0 g/t Au from 160m including 1m @ 404 g/t Au. The funds will add to the recently completed share placement, which raised AUD 3.12 million before costs. The first major deployment of these funds is set to be the planned follow-up drilling at Cox's Find and Mon Ami. This drilling remains on schedule to commence next week. GSN is also pleased to advise that its application to participate in the 2021 Exploration Incentive Scheme has also been successful. This grant will be for up to AUD 150,000 of direct drilling expenditure matched dollar-for-dollar with the Company on the Mt Weld Project, which is immediately adjacent to the Mt Weld Rare Earths Mine, south of Laverton in Western Australia.

Great Southern Mining Limited Reports Significant Gold Intersections from Phase 2 RC Drilling At Its 100%-Owned Cox's Find Project, in the Laverton Gold District, Western Australia Great Southern Mining Limited reported significant gold intersections from Phase 2 RC drilling at its 100%-owned Cox's Find Project, in the Laverton Gold District, Western Australia. This phase focused on two key along-strike targets to the north of the Cox's Find deposit (Targets 2 and 3). The results outlined in this release represent the second phase of a two-phase Reverse Circulation (RC) drill program of 8,216m at the broader Cox's Find Project area. The results of the first phase of 35 RC holes (for 6,032m) were previously announced (see GSN ASX releases dated 29 July, 4 August and 8 September 2020). The second phase comprised 20 RC holes for 2,184m across two northern structural target areas Targets 2 and 3. Results identified a shallow, broad zone of mineralisation associated with quartz veining within the oxide clay zone. The best result was 13m @ 0.7 g/t Au from 34m including 1m @ 1.7 g/t Au (20CFRC0043). Mineralisation is associated with a broad zone of quartz veining and correlates with historic RAB intersections to form a coherent zone of mineralisation in the oxide profile for 150m strike length. The orientation of the quartz veining is yet to be established. Aggressive follow-up drilling is planned to test if mineralisation extends at depth. Target 3 is located approximately 1km north along strike from the Cox's Find deposit. Nine RC holes were drilled at Target 3 for 996m. This drilling delineated a continuous mineralised zone of 200m strike length that remains open to the north and south. Drilling on the northern most line intersected significant mineralisation in a quartz vein host at a lithological boundary between a dolerite unit and sedimentary, Chert-Shale sequence. This sequence is interpreted to be the same lithological package to that of the high-grade Cox's Find deposit and confirms that a mineralised corridor is present. These RC results confirm that historic RAB testing in this area by previous tenement owners was ineffectively shallow and missed the target area. Along with a similar dynamic at Target 2, these RC results demonstrate that large portions of the mineralised corridor remain poorly tested (or untested) by historic drilling, providing further excellent opportunities. Significantly, the very recently granted tenement E38/3476 lies approximately 40m directly north of this northern most line of RC drilling at Target 3. The tenement was still under application at the time of drilling and no ground disturbing activities could take place at that time as a result. The recent results at Target 3 demonstrate the prospectivity of E38/3476, which had already been highlighted as one of the higher-ranked target areas by the structural interpretation work.
