New major risk - Shareholder dilution The company's shareholders have been substantially diluted in the past year. Increase in shares outstanding: 65% This is considered a major 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 Share price has been highly volatile over the past 3 months (19% average weekly change). Earnings have declined by 7.6% per year over the past 5 years. Shareholders have been substantially diluted in the past year (65% increase in shares outstanding).

New major risk - Share price stability The company's share price has been highly volatile over the past 3 months. It is more volatile than 90% of Australian stocks, typically moving 19% a week. This is considered a major risk. Share price volatility 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. It may also indicate 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.

New major risk - Revenue and earnings growth Earnings have declined by 15% per year over the past 5 years. This is considered a major risk. Ultimately, shareholders want to see a good return on their investment and that generally comes from sharing in the company's profits. If profits are declining over an extended period, then in most cases the share price will decline over time unless the company can turn around its fortunes. A trend of falling earnings can be very difficult to turn around. If the company is well already established it may also be a sign the company has matured and is in decline. In addition, if the company pays dividends it will also likely need to reduce or cut them, striking a dual blow to total shareholder returns. Currently, the following risks have been identified for the company: Major Risks Share price has been highly volatile over the past 3 months (18% average weekly change). Earnings have declined by 15% per year over the past 5 years. Revenue is less than US$1m (AU$81k revenue, or US$51k). Market cap is less than US$10m (AU$3.29m market cap, or US$2.07m).

Mamba Exploration Limited Announces Strong Bedrock Conductors Identified at Black Hills Mamba Exploration Limited announced that following the fixed loop electromagnetic survey completed in late December, bedrock conductors have been modelled and drilling planned over the Southern Prospect at the Black Hills Project. The project is approximately 30 km northeast of the Julimar deposit discovered by Chalice Mining and near the town of Bolgart in the Darling Range. The FLEM survey was designed to cover the southern high priority VTEM target. The FLEM data has now been modelled and has identified three bedrock conductors. Two of the conductors are well defined and worthy of immediate drill testing. A diamond drill rig has been secured and is scheduled to mobilise to site on the 19 January, with the drilling expected to take around 14 days to complete. The Fixed loop EM survey was undertaken over the previously identified VTEM helicopter-based EM conductors in the southern prospect at Black Hills.

Mamba Exploration Limited Announces Drilling and Gravity Survey Underway At Hyden REE Project Mamba Exploration Limited announced that it has commenced a detailed gravity survey over the regional gravity anomaly directly east of the historical high-grade clay hosted REE mineralisation and commenced initial drilling around the high grade clay hosted REE mineralisation identified from historical exploration. As announced on the 28th of November 2022, Mamba has entered into an option agreement over the Hyden project where limited historical REE exploration identified up to 46,716 ppm TREO (4.67%) in clay from 12m downhole. The mineralisation was not properly sampled and remains open in all directions. As a result, Mamba is undertaking a 20-hole aircore drilling programme as an initial test of the clay around the original mineralisation to better understand the potential and source of the very high grade clay mineralisation. The drill programme is underway and is expected to be completed in the next week. In addition to the initial drilling, a detailed gravity survey is underway to better define the regional gravity anomaly that was identified in the initial due diligence undertaken on the project. Carbonatite hosted REE deposits are commonly associated with distinctive gravity anomalies, as a result the detailed survey has been planned to better define the regional anomaly and provide direct drill targets. This gravity survey is expected to be completed within a week with inversion modelling to be undertaken to define drill targets. Bekanntmachung • Nov 10

Mamba Exploration Limited Provides Update on the Results of the Reprocessing of the Ashburton/Gascoyne Regional Radiometric Data Mamba Exploration Limited provided an update on the results of the reprocessing of the Ashburton /Gascoyne regional radiometric data. The reprocessing and rebalancing of the thorium radiometric data have highlighted at least eight distinct anomalies within the Company's Ashburton /Gascoyne Project tenements located in the upper Gascoyne region of Western Australia. Recent exploration activities and discoveries made in the region by others (including Dreadnought Resources (ASX DRE) and Kingfisher Mining (ASX KFM)) has highlighted the potential of the region for multiple styles of mineralisation including REE mineralisation. A review of the radiometric data over these discoveries has identified that they have an associated radiometric (thorium) signature. As a result, the Company reprocessed and rebalanced the regional data over the region. This highlighted at least eight discrete anomalies within their tenements which will be visited early next month and the potential of the area will be assessed with the use of a pXRF.

Mamba Exploration Limited Provides Exploration Update on Copper Flats Project Mamba Exploration Limited provided an update of exploration activities at the Copper Flats project in the east Kimberley of Western Australia. Recent exploration activities have included completion of a 2,600 soil sampling survey, portable XRF (pXRF) analysis of approximately half of the soil samples, ground truthing of the AEM anomalies identified and geological investigations of the eastern portion of the project area. Field validation of a number of the historical high-grade surface prospects was undertaken as part of the recent field trip. This included field validation of the high-grade Area 4 outcrop where previous explorers identified rock chip samples up to 30 % Cu and 275 g/t Ag which have not been followed up (as reported in the Mamba Prospectus dated 15 December 2020 and originally reported by Ord River Resources in 2006 (WAMEX Report A74206). The outcrop of the high-grade copper mineralisation at Area 4 was located and re-sampled with full assays pending. This outcrop and the field investigations of other high grade copper prospects has confirmed that the bulk of the surface mineralisation identified to date is located at or near the contact of the Antrim volcanics and the Headleys Limestone, where the flow top breccia and alteration (+/- mineralisation) can be traced for over 50km. This stratigraphic position is variably mineralised, with the zones of higher alteration and mineralisation being associated with the interpreted basin growth faults that can be traced through the eastern portion of the project. While these very high-grade historical results are obvious targets in their own right, the potential for significant sulphide mineralisation at depth needs to be fully evaluated. The most effective way to test the stratigraphic contact and the interpreted basin growth faults at depth for sulphide mineralisation is through the use of airborne EM followed by drilling. As a result, the airborne EM programme that is being flown next month has been adjusted to ensure that the interpreted basinal growth faults are tested with more detailed flight lines. Additionally, as the programme progresses, additional lines will be added where any anomalies are defined and remain unresolved. A total of 6 AEM conductors were visited to try to explain the anomalies. Only one of these anomalies (AEM 2) which is located on a range of small hills which trended NE -SW with substantial structural disruption had any geological or geomorphological feature that could explain the anomaly. In the area of AEM 2, there is an interpreted NE-SW basinal growth fault that is believed to be a key structural position for copper mineralisation in the region. The other conductors visited are covered by Headleys Limestone with no features at surface that could explain the anomalies. A 2,600-point soil sampling programme has been completed at the Ord Hill Prospect at Copper Flats. It was centred around the historical surface sampling which had identified an anomaly of approximately 2,000m by 500m. All the samples have been transported to Perth for analysis, where pXRF analysis is being undertaken. This method provides a quick analysis for the pathfinder and main elements of interest, with the anomalous samples to be submitted for full laboratory analysis. The high priority samples (~1,400 samples) have been tested with the pXRF and have highlighted that the Ord Hill Prospect anomaly that extends for over 4,500m from the northeast to the southwest and 500m north south with results up to 752 ppm Cu. Once all the samples have been analysed using the pXRF, the anomalous samples (+75 ppm Cu) will be submitted for full wet chemistry analysis. Results of the rest of the pXRF and wet chemical analysis will be reported as soon as the data is collected and compiled. Bekanntmachung • Jun 02

Mamba Exploration Limited Announces Completion of Auger Drilling At the Ashburton Gold Project in Western Australia Mamba Exploration Limited announced that auger drilling completed in late 2021 at the Ashburton Gold Project in Western Australia has identified a base of transported cover gold anomaly which extends for approximately 300m by 200m at the Bettina Prospect at Lyndon. The anomaly includes gold anomalism of up to 36ppb gold, which is more than 15 times the background gold level of around 2 ppb gold. The historical rock chip sampling within the workings identified a number of high-grade quartz veins with grades up to 46.5 g/t gold and 4m @ 21.5 g/t gold in historical RC drilling. Mamba has rock chip sampled a number of the quartz veins in the workings and confirmed the mineralisation with grades of up to 36.5 g/t gold identified. Sampling of the waste dump also identified high grade mineralisation of up to 17.6 g/t gold. As a result of the size and strength of the anomaly, a programme of works has been submitted to the department of Mines Industry Regulation and Safety and approval received for RC drilling. The detailed planning for the drilling is underway, however, given the higher priority drill targets that have been identified at the Company's Calyerup Creek Gold Project, drilling of this anomaly is not expected to be undertaken until mid-2022. An auger programme was also undertaken at the Osbourne Well tenement, testing a large regional structure. This auger sampling confirmed a small 26ppb gold anomaly at the Woods Prospect and a number of other very low order anomalies associated with the regional structure, however no significant anomaly was identified.

RC drilling is due to recommence on Friday the 21st of January with the remaining 42 RC holes from the initial programme to be completed. In addition to the RC drilling, a programme of infill soil sampling was also completed in December 2021. This programme was designed to infill the existing soil sampling dataset and to better define the anomalous gold trends identified which extend for a total of 2,800m. This programme was a great success, identifying significant extensions to the mineralisation while also better defining the anomalous gold trends. The peak results were 2.8 g/t gold (2,800 ppb Au) from the southern trend and 1.3 g/t gold (1,300 ppb Au) from the northern trend. These trends remain undrilled and a programme of works (PoW) has already been submitted to the Department of Mines, Industry Regulation and Safety (DMIRS) for an additional 100 RC holes. This drilling will be undertaken once the existing programme of 50 holes has been completed and results compiled and released. Bekanntmachung • Dec 23
Mamba Exploration Announces Multiple Sulphide Zones Intersected At Black Hills Mamba Exploration Limited announced that the second drill hole (21BHRC002) drilled at the Black Hills priority target has intersected multiple zones of disseminated to blebby sulphide mineralisation. Visual logging has been completed on the second hole, which intersected a mafic /ultramafic intrusion and metagranite. The zones of mineralisation are within zones of predominantly gabbronorite and contain poly phase (mixed) magmatic sulphides of pyrrhotite and minor chalcopyrite. Samples from the second hole have been submitted to the laboratory in Perth for analysis, and results are expected in around 4 weeks. Given the success of the first two holes, the third hole is going to be completed using a diamond core tail after a RC pre-collar of 61 metres was completed. The decision to change drilling type has been as a result of the initial holes intersecting sulphides and needing to better understand the geological and structural system that is hosting the sulphide mineralisation. Drilling will be undertaken early in 2022. Bekanntmachung • Dec 20
Mamba Exploration Limited Announces the Discovery of Sulphide Mineralisation in the First Hole (21BHRC001) At the Black Hills Priority Target Mamba Exploration Limited announced the discovery of sulphide mineralisation in the first hole (21BHRC001) at the Black Hills priority target. Visual logging has been completed on the first hole and has identified multiple zones of disseminated sulphide mineralisation. Samples for the priority portion of the hole have been submitted to the laboratory in Perth for analysis, and results are expected to take around 3 4 weeks to be received. RC drilling of two more holes is ongoing and expected to be completed in the next few days, with samples to be submitted this week to the laboratory for analysis. Given the pending Christmas period, results are expected to be received in around 4 weeks after sample submission. In addition to the ongoing drilling, a downhole EM survey team has been secured to survey all completed holes this week. To better define the magnetic anomaly and to better target the drilling, an ultra-detailed (20m line spaced) drone magnetic survey has also been completed over the priority intrusion. This survey will provide far better detailed magnetic data when compared to the current 200m spaced data. It is expected once the magnetic data is processed that 3D inversion modelling along with the downhole EM and geological data from the RC drilling when combined will provide improved drill targeting for the next round of follow up drilling.

Mamba Exploration Limited Announces Drilling Plans At Black Hills Priority Target Mamba Exploration Limited announced that detailed modelling of electromagnetic (EM) and detailed 3D inversion modelling of the magnetic data has confirmed the priority target at the Company's Black Hills Project located approximately 30km North-East of the Julimar PGE-Ni-Cu-Co-Au deposit discovered by Chalice Mining. The modelling has highlighted a conductive and magnetic anomaly that is interpreted to extend for approximately 750m North-East to South-West and extend to a depth of around 400m (the limit of the data). The anomaly is associated with a mapped mafic /ultramafic intrusive feature at the northern end of a +6km long PGE trend (see ASX announcement titled "Mamba confirms priority PGE-Ni-Cu Target at Black Hills" dated 20 July 2021 and figure 6). The anomaly will be tested by three RC drill holes, with a McKay Drilling RC rig secured for the drilling. The Rig is expected to be on site in December, with the drilling completed before the end of the year. Bekanntmachung • Jul 20
Mamba Exploration Limited Announces Priority PGE-Ni-Cu Targets Identified at Black Hills Mamba Exploration Limited reported encouraging results from an airborne electromagnetic (AEM) survey completed over its Darling Range PGE, Ni and Cu project, located near the western margin of the Yilgarn Craton (see Figure 6), approximately 30km east of Chalice Mining's Julimar discovery in Western Australia. Results from the survey have identified two areas as priority targets. At the Black Hills and Batty Bog tenement areas, AEM has resulted in 10 significant AEM plates being modelled. At Black Hills, seven of these plates are associated with a 6km long ultramafic trend in the eastern portion of the tenement. This ultramafic trend is of particular significance as it is supported by numerous coincident geochemical and geophysical trends significantly upgrading the potential of the area. The Black Hills Project area is located approximately 30km east of Chalice Mining's Julimar discovery, north-east of Perth, WA. This area will remain a priority for the Company. In addition to the 2PGE anomaly, compilation of historical rock chip sampling and digitisation of the geological mapping in the area has identified and confirmed an ultramafic unit that is broadly coincident with the anomaly, which extends through the eastern portion of the tenement. Sampling of this unit identified anomalous Ni results, consistent with an ultramafic signature. Bekanntmachung • May 25
Mamba Exploration Limited Announces Commencement of Exploration on Calyerup Creek Project Mamba Exploration Limited announced that it has been granted a new tenement adjoining the Company's existing Calyerup Creek Gold Project- significantly expanding the Project's existing tenure by approximately 70km2. In addition, Mamba has begun initial exploration activities at the Project, including commencement of geochemical sampling, as well as the submission of a Programme of Work (PoW) to the Department of Mines, Industry Regulation and Safety (DMIRS) to approve a planned RC drilling campaign at the Project - anticipated to start in the next month, pending approvals. The Calyerup Creek Gold Project is located in the Great Southern region of Western Australia, and consists of two granted exploration licences near the contact of the Albany Frazer Complex and the Yilgarn Craton. The area is dominated by high-grade metamorphic rocks similar to the Albany Frazer complex known to host significant gold deposits, including the Tropicana Gold Mine. Other than some soil sampling which identified a 4km long soil anomaly in 1988, the Project has had very little modern exploration. The Project has historically undergone regional wide spaced soil sampling, which identified a ~4km long soil anomaly. Within the broad anomaly, a number of higher-grade portions were defined, three of which have been partly tested with shallow drilling, while a number of smaller high- grade trends remain untested. Additional sampling is underway to better define all of the anomalies and to close off the anomalies to allow the targets to be prioritized for drilling. New Tenement Granted: After Mamba listed on the ASX in February 2021, the Company identified a granite greenstone contact and a number of structural trends on open ground south of the Company's original Calyerup Creek tenement. A tenement application was submitted and has now been granted. The geochemical sampling underway at Calyerup Creek will extend onto the recently granted tenement, allowing rapid target generation to be undertaken. The area has no historical exploration; however, it contains the southern extension of the greenstone unit that hosts the mineralization at the Northern, Central and Southern prospects at Calyerup Creek. This sampling will be undertaken immediately after the high priority sampling over the original tenement has been completed. Planned Drilling: Lastly, A PoW has been submitted to DMIRS for approval to drill approximately 50 shallow RC holes on the Project. So far, 30 RC holes have been planned around the southern workings to test for extensions of the prospect, both along strike (to the north west and to the south east) and at depth. Historically, this prospect has only been drilled to a vertical depth of approximately 25m and remains open. The remaining 20 RC holes plan to test previously undrilled geochemical anomalies in the southern portion of the Project. The Company has already secured an RC drill rig for the programme and is expected (subject to PoW approval) to commence drilling in the next month. The planned RC drilling is based on the historical data that has been validated on the ground during two recent field trips - separate from the current geochemical sampling programme which is also underway.

Mamba Exploration Limited Announces Commencement of VTEM Survey on Darling Range Project Mamba Exploration Limited announced that the Electro Magnetic (EM) survey over the Darling Range Project has commenced. The survey has started at the Mistake Creek tenement that neighbours the Mandrake Resources Jimperding Project, where a recent EM survey identified a number of strong EM conductors, some of which appear to trend into M24's tenure. This portion of the survey is expected to be completed by the 19th of March. The second area to be tested is the Black Hills tenement, which is located between Chalice Mining's Julimar Discovery east of Perth and the recent strong EM conductor discovery made by Pursuit Minerals. The third area will test the Batty Bog tenement, which is located north of New Norcia, between Caspian Resources Yarawindah Brook Project, where there have been significant PGE drill intersections and a number of EM conductors and the recent significant gold discovery made by Liontown Resources which included 44m @ 1.6 g/t gold including 20m @ 3.2 g/t gold. Subject to weather conditions, the survey is expected to be completed in the next 10 days with preliminary results expected within two weeks of completion of the survey. Bekanntmachung • Feb 24
Mamba Exploration Limited Announces Electro Magnetic (EM) Survey At the Darling Range Project Mamba Exploration Limited advised that it has secured an Electro Magnetic (EM) survey crew to undertake the airborne geophysical survey over the Darling Range Project in mid-March. The Darling Range Project is located between Chalice Mining's Julimar Discovery, east of Perth, and the recent strong EM conductor detected by Pursuit Minerals. The project also adjoins the Mandrake Resources Jimperding Project where a recent EM survey identified a number of strong EM conductors - some of which appear to trend into M24's tenure. The VTEMtm survey has been designed to cover all the prospective trends identified from the regional magnetic datasets, and will be flown using 200m spaced lines and a loop height of 35m providing good resolution and depth penetration for the survey. Although the survey has been delayed by a week as a consequence of Pursuit Mineral's decision to extend their survey following the discovery of a number of strong conductors on their Calingiri East tenement, located 10km east of M24's Black Hills tenement, company to secure one of the few helicopter based EM crews to fly the survey so soon after listing. An initial field visit to the project has been undertaken to assist in planning the EM survey and to identify priority target areas. This field trip confirmed the access, assisted in the planning of the geophysical surveys, and has identified a number of target areas that will be covered by the VTEMtm survey. In addition to the exploration activities at Darling Range, the Company has also applied for an additional exploration licence at the Calyerup Creek project in the Great Southern region of Western Australia. The additional tenure extends the project approximately 9km to the south and covers the margin of a granite and a north south trending mafic and sedimentary package of metamorphic rocks.
