Announcement PDF Unit 1, 4 Burgay Court, Osborne Park, WA 6017 +61 8 9473 8345 info@dreres.com.au www.dreadnoughtresources.com.au ASX:DRE Dreadnought Resources Ltd 1 ASX ANNOUNCEMENT 4 May 2026 Exceptional Gold Recoveries from Metzke’s Find – Illaara Au (100%) HIGHLIGHTS • Five composite samples representing various grades from Metzke’s Find were submitted to confirm recoveries from conventional gravity and carbon in leach (“CIL”) circuits. Results across four grind sizes are exceptional with: o Combined gravity and CIL recoveries averaging 98.9%; and o High gravity recovery averaging 78.5% and up to 91.0% • Test work confirms that mineralisation at Metzke’s Find is free milling (non-refractory) and amendable to conventional extraction methods including strong gravity recovery. • These results will provide further positive input into a study for Metzke’s Find. The already high-grade 2023 Resource (14,900 oz @ 6.8 g/t Au) will be updated and upgraded in July 2026 following drilling results. Dreadnought Resources Limited (“Dreadnought”) is pleased to announce metallurgical test results from Metzke’s Find, part of the 100% owned Illaara Gold Project, located in the Yilgarn region of Western Australia. Dreadnought’s Managing Director, Dean Tuck, commented: “These exceptional metallurgical results highlight the quality of the coarse- grained free-gold mineralisation at Metzke’s Find and strongly support our strategy to transform into a self- funded explorer through the development of both Star of Mangaroon and Metzke’s Find, that can be commercialised. These results will be included in the updated Resource in July 2026, which will be followed by completion of a study”.

The results confirm exceptional recoveries using conventional gravity and CIL processing. Key results after 48 hours were: • Combined gravity and leach recovery averaged 98.9% across all grind sizes and 99.5% at 75μm grind size. • Gravity gold recovery averaged 78.5% at 212 μm grind size. • Rapid leach kinetics with extraction largely completed within 8 hours. The test-work was carried out on five composite samples which were selected to represent a range of head grades and locations within the planned updated and upgraded Resource (Table 1 and Figure 2). The tests were conducted using Perth tap water and completed by independent metallurgical consultants, Strategic Metallurgy. Additional metallurgical and geotechnical test work is planned following the updated and upgraded Resource. Table 1: Summary table of the gold recovery test work.

Samples were ground using a rod mill and the resultant feed was upgraded using a Falcon concentrator. Results showed high gravity recoveries as shown in Table 1 above. Gravity recoveries range from 65–91% with an average gravity recovery of 78.5% using a coarse grind size of 212µm. Recovery was highest with sample S4 which was selected as a low-grade composite based on the drill hole assays (MZRC078 2m @ 1.3g/t Au from 39m). The calculated grade of the sample from the metallurgical test-work was 5.1g/t highlighting the coarse-grained free gold nature (nuggety) of the mineralisation. However, all gravity recovery results are well above industry averages and reflect the high-grade and coarse nature of the gold throughout the deposit. CIL Recovery CIL tests were carried out at four different grind sizes using the gravity tails to characterise the performance at different grind sizes. Samples were milled and then transferred to a bottle where reagents were added to achieve a pH of 10. The favourable leach extraction and associated reagent consumption results are also shown in table 1 above. Results from all samples show exceptional overall recoveries with moderate reagent consumption in line with typical gold deposits.

The remote location, being 160km from the nearest railhead, and lack of readily available fresh water limited follow-up work. Metzke’s Find was worked on a few occasions over the following decades for a recorded production of ~890 oz @ ~40 g/t Au. Metzke’s Find comprises ~20 small, historic shafts over ~700m of strike. The only significant exploration at Metzke’s Find was in the late 1980s and early 1990s by junior gold explorers who drilled shallow percussion holes (average ~24m) which recorded a number of attractive results, including: MZ07: 5m @ 4.0 g/t Au from 11m MZ25: 1m @ 18.0 g/t Au from 22m MZ19: 2m @ 15.7 g/t Au from 19m MZ23: 3m @ 11.7 g/t Au from 18m Dreadnought acquired Metke’s Find in 2020 and has completed RC and diamond drilling, which also delivered significant results including: MZRC022: 4m @ 10.5 g/t Au from 19m MZRC017: 7m @ 7.5 g/t Au from 51m MZRC019: 4m @ 19.9 g/t Au from 45m MZRC016: 3m @ 21.0 g/t Au from 85m Mineralisation at Metzke’s Find is hosted within a series of stacked, moderately dipping quartz lodes up to 4m thick that occasionally overlap within a mafic sequence with sulphidic interflow sediments. The main deposit scale structural control is a north-south trending shear zone that consists of a series of steep (70–90˚) southwest dipping shear planes and parallel quartz veins with dominate sinistral reverse movement and moderate to steep (55–70˚) west dipping schistosity. The intersection between shear planes and shear schistosity controls an apparent north shoot plunge. In 2023, a Resource (72% Indicated) was declared with the majority of mineralisation being contained within 140m of surface. The current Resource is shown below. Metzke’s Find remains open along strike and at depth.

Unit 1, 4 Burgay Court, Osborne Park, WA 6017 +61 8 9473 8345 info@dreres.com.au www.dreadnoughtresources.com.au ASX:DRE Dreadnought Resources Ltd 4 Background on Illaara Illaara is a consolidated landholding covering ~800km2 and ~70km strike of a greenstone belt located ~190km from Kalgoorlie. Illaara is one of the most underexplored greenstone belts in the Yilgarn Craton and is situated near mills at Davyhurst (OBM.ASX) and Bottle Creek (Aurenne). Historically gold was worked at Metzke’s Find and the nearby Lawrence’s Find in the early 1900s. However, the remoteness, lack of water and access hindered early prospecting. Recent exploration within Illaara was spurred on by a ~55km long Au-As-Sb anomaly generated from regional regolith sampling by the Geological Survey of Western Australia which led to Newmont acquiring Illaara in 2016. Prior to Newmont, iron ore companies held the project as part of the Koolyanobbing Iron Ore Operation. Given the long history of iron ore mining in the region, Illaara is well situated in relation to existing road and rail infrastructure. Dreadnought acquired Illaara from Newmont in 2019 and has consolidated the rest of the greenstone belt through a series of acquisitions. Early drilling by Dreadnought focused on the historical workings at Metzke’s Find resulting in a high-grade Resource (14,900 oz @ 6.8 g/t Au) that remains open along strike and at depth. Given the lack of systematic exploration, Illaara presents a strong opportunity to make a major gold discovery within the world-renowned Yilgarn Craton. Figure 3: Map showing the location of Illaara relative to other gold operations and major players in the region.

Consolidation Provides for First Ever Modern Exploration • All historical workings and known gold occurrences relate to outcropping mineralisation. There has been minimal historical and modern exploration due to remoteness and iron ore exploration. • 2026 will see the first ever systematic air core drilling program undertaken across the belt, a drilling program that previous owners Newmont wanted to undertake prior to Dreadnought acquiring the project in 2019 and consolidating the remainder of the belt. Significant, Step-change, Growth Potential • Illaara contains multiple highly prospective structural corridors with known gold anomalism providing near term drilling targets and discovery potential. • Dreadnought is deploying modern geochemical and geophysical techniques to explore for mineralisation under shallow cover. Shallow, High-grade Gold at Metzke’s Find • The Resource at Metzke’s contains shallow, high-grade gold which provides a strong foundation for the project. • Mineralisation at Metzke’s Find remains open along strike and at depth.

This includes a high-grade open pit at the Metzke’s Find where funding, development, haulage & processing are outsourced to third parties. This is a common model in WA given the robust gold price. In this way, there is reduced reliance on market funding and internal cashflows are aimed at making life-changing discoveries.

Since 2020, Dreadnought has identified three major focus areas within the Mangaroon Project: Mangaroon Gold (100%) Outcropping gold mineralisation was first identified and mined at Mangaroon by local pastoralists and prospectors in the 1960s and has seen no modern gold exploration. Dreadnought has consolidated this gold field and is undertaking the first modern exploration across the region which has identified five camp scale gold opportunities at Bordah, High Range, Alma, Minga Bar and Star of Mangaroon. In addition, the project contains granted mining leases that provide an opportunity for cashflow including the Star of Mangaroon Mine where Dreadnought has delivered a 27,000 oz Resource at 11.1 g/t Au (98% Measured and Indicated) Gifford Creek Critical Metals (100%) Dreadnought discovered the Yin Ironstones and the Gifford Creek Carbonatite in 2021. Since then, the Gifford Creek Carbonatite Complex has emerged as a globally significant, rapidly growing, potential source of critical minerals. Highlights include: • Discovery of the Yin REE Ironstone Complex and delivery of a 30.0Mt @ 1.04% TREO Resource over only ~4.6km – including a Measured and Indicated Resource of 26.3Mt @ 1.04% TREO (ASX 30 Nov 2023). • Discovery of the globally significant, Nb-REE-P-Ti-Sc enriched Gifford Creek Carbonatite (ASX 7 Aug 2023). • Delivery of a large, independent initial Resource of 10.8Mt @ 1.00% TREO at the Gifford Creek Carbonatites, containing a range of critical minerals including rare earths, niobium, phosphate, titanium and scandium (ASX 28 Aug 2023). • Discovery of Stinger Nb-REE-P-Ti-Sc-Zr bearing carbonatite and delivery of the Stinger Niobium Exploration Target (ASX 3 Mar 2025, 29 Sept 2025). Money Intrusion Ni-Cu-PGEs (Teck Earn-In) The Money Intrusion is a ~45km long mafic intrusion prospective for Ni-Cu-PGE massive sulphides. In 2023, Dreadnought discovered high tenor nickel-copper massive sulphides confirming the potential of this new system. Dreadnought entered in to a $15M Farm-In and Joint Venture agreement with Teck Resources, a leading Canadian resource company, to earn up to 75% of the Money Intrusion tenements. Illaara Gold Project (100%) Illaara is located ~190km northwest of Kalgoorlie in the Yilgarn Craton. The project comprises ~800km2 covering ~70km of strike along the Illaara greenstone belts. Illaara was acquired off Newmont in 2019 as an early stage exploration project prospective for typical Archean mesothermal lode gold deposits. Dreadnought has delivered a 14,900 oz @ 6.8 g/t Au Resource at Metzke’s Find (72% Indicated). Prior to consolidation by Dreadnought, Illaara was predominantly held by iron ore explorers and remains highly prospective for iron ore amongst other commodities. Kimberley Cu-Au-Sb Project (Tarraji 80% / Yampi 100%) Tarraji-Yampi covers ~420km2 is located only 85km from Derby in the West Kimberley region of WA and was locked up as a Defence Reserve since 1978. The project has outcropping mineralisation and historical workings which have seen no modern exploration. In 2021, Dreadnought discovered high grade Cu-Au massive sulphides at Orion with results to date indicating a large scale, Proterozoic Cu-Au VMS system at Tarraji-Yampi, similar to DeGrussa and Monty in the Bryah Basin. In addition, the project contains outcropping high-grade Cu-Ag-Sb-Bi Veins at Rough Triangle and Grant’s Find.

Criteria JORC Code explanation Commentary Sampling techniques • Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc.). 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 (e.g. ‘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 (e.g. submarine nodules) may warrant disclosure of detailed information. Reverse Circulation (RC) drilling was undertaken to produce samples for assay. RC Drilling Two sampling techniques were utilised for the RC drilling, 1m metre splits directly from the rig sampling system for each metre and 3m composite sampling from spoil piles. Samples submitted to the laboratory were determined by the site geologist. 1m Splits From every metre drilled a 2-3kg sample (split) was sub- sampled into a calico bag via a Metzke cone splitter from each metre of drilling. 3m Composites All remaining spoil from the sampling system was collected in buckets from the sampling system and neatly deposited in rows adjacent to the rig. An aluminium scoop was used to then sub-sample each spoil pile to create a 2-3kg 3m composite sample in a calico bag. A pXRF is used on site to help determine mineralised samples. Mineralised intervals have the 1m split collected, while unmineralised samples have 3m composites collected. All samples are submitted to ALS Laboratories in Perth for determination of gold by Photon assay from crushed sample (ALS Method Au-PA01). Select samples are also submitted for 48 multi-elements via 4 acid digestion with MS/ICP finish (ALS Code ME-MS61) to assist with lithological interpretation. QAQC samples consisting of duplicates, blanks and CRM’s (OREAS Standards) are inserted through the program at a rate of 1:50 samples. Drilling techniques • Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc.). RC Drilling Drilling was completed by Precision Exploration Drilling (PXD) utilising a DRA 600 truck mounted drill rig with additional air from an auxiliary compressor and booster. Bit size was 5¾“. Drill sample recovery • Method of recording and assessing core and chip sample recoveries and results assessed. • Measures taken to maximise sample recovery and ensure representative nature of the samples. • Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. RC Drilling Drilling was undertaken using a ‘best practice’ approach to achieve maximum sample recovery and quality through the mineralised zones. Best practice sampling procedure included: suitable usage of dust suppression, suitable shroud, lifting off bottom between each metre, cleaning of sampling equipment, ensuring a dry sample and suitable supervision by the supervising geologist to ensure good sample quality. Logging • Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. • Whether logging is qualitative or quantitative in nature.
