HIGHLIGHTS The Project area has substantial recorded tin production (162t), a review of the data revealed: • 150 historic drill holes (7,672 m) across the Walwa Tin-Tantalum Project have now been fully compiled into a digital database and verified against the original reports. This is made up of 78 RC (2,847 m), 59 percussion (4,235 m) and 13 diamond holes (590 m);13,14,15 • Dart Mining’s interpretation (Figure 3) is that the apical zone of the stacked, dome forming, sub- horizontal aplite-pegmatite-greisen dykes at Walwa is an obvious target for deeper drilling. • Data review and tin mineralisation models generate two high-priority drill targets: 1. Larger tonnage high-grade greisen hosted tin mineralisation at the top of an underlying late-stage felsic causative intrusion, presumed to be 400m to 600m below surface (Figure 3). 2. Repeating mineralised aplite-pegmatite sub-horizontal dykes at depth below the multiple drilled dykes (known to be up to 5-18m in thickness). Seismic survey17, 18 has indicated another four 4+m thick dykes at depth below known tin mineralised dykes. • Historic pre-JORC estimates1 at the Walwa (Mt Alwa) tin mine include 8.64Mt @ 0.163% Sn (~0.21% SnO2) & 50ppm Ta2O5 (Union Corp. March 1982)13 , and a higher-grade selective zone of 993,000t @ 0.38% Sn (~0.48% SnO2) & 55ppm Ta2O5 (Union Corp. September 1983)14 ; • Historic drilling highlights1 are listed in Table 1 (full drill results in Appendix Two), and include: ▪ 5.1m @ 0.34% SnO2 from 7.5m and 6.1m @ 0.58% SnO2 from 35.1m in DDH2 (Mt Alwa) ▪ 9m @ 0.32% SnO2 from 54m and 11m @ 0.24% SnO2 from 70m in WRC0011 (Mt Alwa) ▪ 8m @ 0.29% SnO2 from 43m and 6m @ 0.18% SnO2 from 79.5m in UP0004 (Mt Alwa) ▪ 9m @ 0.38% SnO2 from 89m in UP0016 (Mt Alwa) ▪ 18m @ 0.18% SnO2 from 42m in WRC0013 (Mt Alwa) ▪ 5.3m @ 0.51% SnO2 from 0.3m in DDH5, 6.2m @ 0.17% SnO2 from 11.4m in DDH6, and 2m @ 0.71% SnO2 from 18m in WRC0075 (The Bounce mine area) ▪ 6m @ 0.17% SnO2 & 758 ppm Ta2O5 from 1m in WRC0039, and 11m @ 0.13% SnO2 & 356 ppm Ta2O5 from 0m in WRC0043 (Mt Alwa South area) • Diamond drilling of the two high-priority targets is expected to commence in October 2026. 2 | P a g e 1 Please note, the reported information has been extracted from external reports. Full details of the date and location of the report are as separately referenced below. The reported information has been reviewed in the context of completing the JORC Table 1, Section 1 and 2 below. It is uncertain that following evaluation and/or further exploration work that the reported information will be able to be replicated. Nothing has come to the attention of the Company that causes it to question the accuracy or reliability of the historically reported Exploration Results; but readers are advised to review the JORC Table 1 for full disclosure of the rediscovery of these exploration results and the lengths to verify the information that Dart Mining has undertaken. The historical estimates referred to in this document are historical estimates and are not reported as Mineral Resources or Ore Reserves in accordance with the JORC Code (2012). The Competent Person has not done sufficient work to classify the historical estimates as Mineral Resources or Ore Reserves, and it is uncertain that following evaluation and/or further exploration work the historical estimates will be able to be reported as Mineral Resources or Ore Reserves in accordance with the JORC Code (2012). Dart Mining is not treating the historical estimates as current Mineral Resources or Ore Reserves. The information provided under ASX Listing Rules 5.12.2 to 5.12.9 is an accurate representation of the available data and studies for the material historical estimates. Dart Mining’s Chairman, James Chirnside, commented: “Review of historic exploration and mining data from the Walwa tin mine area has greatly enhanced our understanding of the tin mineralisation and has generated two high-priority drilling targets in addition to the large known tin mineralised system. Proposed diamond drilling is planned to commence in October 2026 to test these large and exciting targets.” Dart Mining holds 100% owned granted tenements at Walwa (EL007426 – 499sq.km), Cudgewa (EL006866 – 508sq.km) and Berringama (EL007170 – 27sq.km) which are shown in Figure 1. Figure 1 – Tenement location showing historic tin and tungsten mines and prospects 3 | P a g e WALWA TIN GEOLOGY AND MINERALISATION MODEL The Walwa tin-bearing pegmatites are genetically sourced from the larger parent Koetong Granite body, representing a highly fractionated offshoot of the same Silurian magmatic event. Both belong to the broader Silurian S-type Koetong Supersuite of granites characteristic of the Wagga Tin Belt (Figure 2) in the Lachlan Fold Belt.12 The pegmatite, aplite and greisen dykes of the Walwa tinfield emanate outward into the surrounding metamorphic complex, probably as a late stage fractionated offshoot from the main Koetong Granite intrusive source (containing tin as it behaves as an incompatible element when common minerals such as quartz and feldspar are crystallized). Following fractionation late-stage magmatic-hydrothermal processes squeezed out the tin bearing fractionate into peripheral fractures to form the pegmatite-aplite- greisen system at Walwa.12&13 In other tin systems similar to Walwa the metal rich fluid and vapour rise up and collect at the roof or apex of the granite. The acidic fluids react with the granite causing alteration which converts feldspars into quartz- mica assemblages known as greisens. The destruction of feldspars consumes acid destabilizing the dissolved tin complexes causing oxidation and precipitation of cassiterite (SnO2), the primary ore mineral of tin. Greisen zones host many large world class tin deposits around the globe and are an exciting target for exploration beneath the Walwa tin mine. For example, the Altenberg region of Germany and the Czech Republic with 300,000t of recorded tin production. Higher grade mineralisation towards depth5 potentially highlights vertical zonation often reported in stacked pegmatite hosted Sn deposits such as Altenberg and the possibility of higher grade resources at depth. Figure 2 – Overview of the Wagga Tin Belt (from DTM:ASX 11 August 2026) 4 | P a g e The Walwa tin-bearing pegmatites/aplites typically occur as 1–10 m-thick shallow-dipping, stacked dykes. Figure 3 shows the repeated tin mineralised dykes with two thick dykes (4-12m thick) and several thinner dykes known from the open pit and shallow historical drilling. Reflection seismic studies17,18 have shown at least four thick dykes occur beneath the known drilled ones with the seismic study demonstrated to only locate dykes over 4m in thickness. Dykes range from aplitic to pegmatitic in texture, and mineralised outcrops commonly display quartz–mica–sericite alteration assemblages with Sn–Ta mineralisation locally abundant. The upper dyke at the Walwa (Mt Alwa) tin mine was last worked in the late 1960s with the material drilled and blasted at surface and then pushed up with a bulldozer. This material was then processed without any further selection and resulted in recovered grade between 0.1 and 0.2% Sn for the 97,000t processed.3,9 Figure 3 – Interpreted geology and high-priority tin mineralised targets at the Walwa Tin Mine 5 | P a g e Table 1 – Peak drill intercepts for historical drilling across the Walwa tin mine area on EL0074261 – Walwa main pit area (Mt Alwa mine) unless stated.

Figure 4 shows the location of the historical drilling and tin prospects at Walwa. Every collar, survey, lithology and assay record was reconciled across the original reports into a digital database. The database now comprises 150 located collars, 3,000 logged lithology intervals and 774 assayed intervals. The coordinate datum of the historical grid was confirmed as AGD66 / AMG Zone 55; all coordinates in this announcement are reported converted to GDA94 / MGA Zone 55. Material limitations of the historical data remain and are set out in the JORC Table 1: no downhole surveys were taken in any program (all hole paths assumed straight), no QAQC records exist, sample recovery was not recorded, assay records for the 24 shallow P-series percussion holes have not been located, and the P- series collar positions are a nominal designed grid. These drill holes still inform the targeting conclusions in this announcement. Dart Mining's compilation has recovered quality-control information not previously reported. In 1983 Union Corporation split ten homogenised pulps of diamond core from UD0003 and UD0005 between four laboratories.¹⁴ ALS Laboratories, which had carried out all routine project assaying, returned the lowest tin value in all 10 samples submitted, averaging 22% below the other three laboratories for tin and 19% for tantalum. Union identified that a discrepancy between percussion and diamond drilling was present which they concluded probably under-estimated the overall grade in the percussion drilling.¹³ This is based on two Union diamond holes that were collared alongside percussion holes (twinned holes). The historical logs are consistent with recovery problems in mineralised ground, recording "fine grained aplite sill with visible cassiterite, poor recovery" in UP0018 and a hole abandoned in broken ground with "very poor recovery" in UP0002 and could be explained by percussion drilling not being able to lift the denser cassiterite as representatively as diamond drilling. 8 | P a g e Figure 4 – Plan location of recovered and digitised drill hole database for Walwa HISTORICAL MINERAL RESOURCE ESTIMATES - WALWA TIN MINE Multiple pre-JORC historical estimates have been reported for the Walwa (Mt Alwa) tin mine, all by Union Corporation (Australia) Pty Ltd during the 1980-83 exploration of EL1248. None was prepared under any edition of the JORC Code, no resource classification was applied, and none can be relied upon as a current Mineral Resource1 . September 1981 (G30764)18 : approximately 4.87 million tonnes @ 0.16% Sn and 47ppm Ta2O5 at the Mt Alwa Prospect. 9 | P a g e Delineated aplite-pegmatite, March 1982 (G30765)13 : following completion of 29 percussion holes (2,221m) and two diamond holes, approximately 8.64 million tonnes of aplite-pegmatite defined at the Mt Alwa Prospect at overall grades of 0.163% Sn (approximately 0.21% SnO2) and 50ppm Ta2O5. Union noted that its diamond core results indicated the percussion assays had probably under-estimated the overall grade. Open cut potential September 1983 (G30768)14 : approximately 6.84 million tonnes @ 0.16% Sn and 47ppm Ta2O5 at the Mt Alwa Prospect, based on intersections in nine diamond and five percussion holes. Higher Grade Geological Resource, September 1983 (G30768)14 : 993,000 tonnes @ 0.38% Sn (approximately 0.48% SnO2) and 55ppm Ta2O5. The report cites an estimated 6:1 strip ratio. This estimate was compiled from the enriched portions only of the sills intersected in six drill holes, within a scoping-level discounted cash flow study of a 100,000 tonne-per-annum selective mining operation (DCF rates of return of 2.9-10.5% at Ta2O5 prices of US$30-60/lb). The estimates are historical estimates reported under ASX Listing Rule 5.12. They are based on percussion- dominated drilling with no QAQC records, no downhole surveys and no recorded bulk density determinations, and the estimation methodologies are only partially documented in the source reports. Dart Mining has compiled and verified the underlying drill data (see Historic Drill Database Compilation and Verification above) but has not undertaken the confirmatory drilling, density work or interpretation and review of potential for a Mineral Resource at this stage. A later conceptual "potential resource" figure appearing in a 2009 annual report is not considered by Dart Mining to have been prepared with sufficient rigour to warrant reporting, and is addressed in JORC Table 1 Section 3 only, despite it being a larger estimate.16 The supporting information required by Listing Rules 5.12.2 to 5.12.9 is set out in Section 3 of the JORC Table 1 appended to this announcement. GEOLOGY OF THE WALWA TIN ZONE A number of shallow dipping tin-bearing greisenous aplite/pegmatite dykes are found in the Walwa-Mt Alwa historic mine area and have been worked at various periods for a century with mining first commencing around 1882 with large open pit workings developed in the 1970s. The sub-horizontal dykes cut across the vertical metasedimentary country rocks. The country rocks are knotted schists, phyllites and quartzites found throughout the region. The prominent foliation/ bedding strikes at 160° magnetic with vertical or subvertical dips. Joints are irregularly developed with variable direction and dip. At the Walwa mine four major dykes can be recognised at surface and in addition two other dykes were detected during previous drilling. These dykes are from 1 to 8 metres thick, with variable strike. They generally dip at 20-30° to the north or north-east in the vicinity of the Walwa mine but form a dome with dip becoming north westerly as one traverses west from the historic mine. The dykes themselves are predominantly aplite with pegmatite and greisen phases, often containing coarse cassiterite along their margins and large potassium feldspar crystals. Tantalum and Niobium have been recorded in previous assays from the project area2 . Walwa is an early drill target for multiple sub-horizontal tin lodes to 8m thickness and a possible tin rich greisen zone at the top of a causative intrusion. 10 | P a g e THE BOUNCE The Bounce lode is a sub-horizontal pegmatite dyke with a vertical dyke interpreted as a feeder structure from a causative intrusion. Workings were limited to a few shallow pits of small extent with the largest being approximately 25m by 12m and around 3m deep. MT ALWA SOUTH The Mt Alwa South prospect is located around 500m SSW of the Walwa tin mine and appears to have been discovered and drilled after 1960 with no recorded historic production. Minor historic alluvial tin workings were observed in the narrow gullies leading from the area. Mt Alwa South has four existing bulldozed benches which served as drilling locations for previous RC percussion drilling. These benches are cut into the hillside with switchback connections at the bench end, each bench is 10m to 15m higher in elevation than the last. Sub-horizontal aplite-pegmatite dykes 3m to 8m thick are present (Figure 4). Alderan5 concluded that, “Review of the Walwa Sn-Ta prospect indicated that historical exploration and drilling may have penetrated the top margins of a larger mineralized body with 3D modelling showing grades increasing to depth and magnetic data indicating that the drilled mineralisation lies on the margins of a larger intrusion. The Walwa Sn-Ta prospect shows significant potential for higher grade extensions of mineralisation with depth, where Sn grades appear to increase, and towards the west where historic stream sediment sampling shows anomalous Sn over a magnetic anomaly.” Figure 4 – Mt Alwa South showing outcrop of pegmatite dyke and bulldozed bench previously used for drill access. 11 | P a g e NEXT STEPS • Consider theoretical tin mineralisation models and historical exploration results at Walwa tin mine to determine optimum drilling locations and depths; and • Drill deep holes testing stacked aplite/pegmatite targets, feeder structures and greisen zones at the top of an underlying causative intrusion. Diamond drilling is anticipated to commence in October 2026. Approved for release by the Board of Directors.

These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are Material to the Public Report. • In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine
