This program is supported by cofunding from the WA Government’s merit-based Exploration Incentive Scheme (“EIS”) and a drill for equity agreement with Topdrill Pty Ltd. Dreadnought Resources Limited (“Dreadnought”) is pleased to announce that RC drilling has been completed at the Tiger Cu-Au-Zn-Ag VMS prospect, part of the Mangaroon Gold project, located in the Gascoyne Region of Western Australia. Dreadnought’s Managing Director, Dean Tuck, commented: “Tiger is off to a roaring start with significant mineralisation and five off-hole conductors identified in the first ever drilling program. We look forward to returning to Tiger to test the offhole conductors which have a geophysical signature consistent with massive sulphides. The lab is filling up with drill samples from our gold, niobium and base metal targets at Mangaroon and we look forward to announcing a steady stream of results over the coming months”.

Initial focus is on the ~15km x 10km gold and base metals system situated over the Mangaroon Shear Zone between the crustal scale Minga Bar and Edmund Faults with multiple phases of intrusions. • Genuine camp scale potential with 5 historical mines (Star of Mangaroon, Popeye, Two Peaks, Lead and Pritchard Well) developed on outcropping mineralisation and numerous historical workings along the Mangaroon Shear Zone which have only seen limited, shallow drilling along ~200m of strike near the Star of Mangaroon mine. Transformation into a self-funded explorer • Potential high-grade open pit at the Star of Mangaroon is being progressed whereby funding, development, haulage & processing is to be outsourced to third parties. This is a common model in WA given the robust gold price and, once successful, could be extended to Popeye, Two Peaks, Lead, Pritchard Well etc. Consolidation Provides for First Ever Modern Exploration • All historical workings and occurrences were discovered by pastoralists and prospectors over outcropping mineralisation. There has been minimal historical and modern exploration due to fractured, small-scale ownership. Large scale modern exploration is now being undertaken for the first time under Dreadnought’s consolidated ownership. • Dreadnought is deploying modern geochemical and geophysical techniques to explore for mineralisation under shallow cover. Initial geochemical and geophysical surveys have already generated new prospects with stronger and larger signatures than the historical mines, including the region’s largest high-grade producer at the Star of Mangaroon mine. Shallow, High-grade, Au-Ag Potential • • The Star of Mangaroon mine contains significant shallow high-grade gold intersections including (ASX: 6 Jun 2023, 4 Sep 2023, 11 Dec 2023, 22 Jan 2024): MA10: 4m @ 26.0 g/t Au from 9m MA17: 7m @ 14.3 g/t Au from 21m SOMRC004: 9m @ 13.4 g/t Au from 9m SOMRC005: 7m @ 23.0 g/t Au from 53m SOMRC006: 8m @ 15.5 g/t Au from 89m SOMDD001: 1.4m @ 87.9 g/t Au from 16m Rock chip results from regional prospects and historical workings include: MNRK0515: 74.8 g/t Au (Diamond) TPRK05: 41.7 g/t Au (Two Peaks) SM7: 121.2 g/t Au, 179 g/t Ag (Popeye) RNLYD048: 30.1 g/t Au, 552 g/t Ag (Popeye) Emerging Cu-Au-Zn-Ag System • Sub-cropping gossans covering a >500m strike length highlight the potential for a substantial base metals system with recent rock chips at Tiger including (ASX: 20 May 2024, 20 May 2024, 18 Jun 2024): TIG006: 4.3% Cu, 1.4% Zn, 22.5g/t Ag and 0.2g/t Au TIG010: 2.2% Cu, 7.9% Zn, 30.5g/t Ag and 0.2g/t Au TIG013: 1.9% Cu, 17.5% Zn, 289.0g/t Ag and 0.3g/t Au TIG026: 8.7% Cu, 9.0% Zn, 40.7g/t Ag and 1.0g/t Au TIG027: 10.5% Cu, 4.6% Zn, 16.3g/t Ag and 1.0g/t Au TIG025: 2.4% Zn, 6.3% Pb, 409.0g/t Ag and 0.1g/t Au dreadnoughtresources.com.au 2 ASX:DRE +61 (08) 9473 8345 info@dreres.com.au Unit 1, 4 Burgay Court Osborne Park WA 6017 ABN 40 119 031 864 Overview of Drilling: Tiger Cu-Au-Zn-Ag Prospect (100%) Tiger is defined by a ~500m long sub-cropping gossanous horizon within a coincident ~900m x 300m Cu-Au-Zn-Ag and pathfinder-in-soil anomaly. Tiger contains some of the strongest Cu-Au-Zn-Ag rock chips and pathfinder anomalism defined to date at Mangaroon. The Cu-Au-Zn-Ag gossans appear to have formed after massive sulphides and, given the strong pathfinder association, are considered to be related to VMS style or intrusion-related mineralisation. The first ever drill program at Tiger comprised a total of 8 RC holes (1,456m) which were drilled to test the ~500m strike of sub-cropping mineralisation including 5 shallow holes and 3 deeper holes which served as platforms for DHEM and DHMMR geophysical surveys. Drilling generally intersected multiple zones of variable base metal mineralisation with variable chlorite-magnetite-carbonate alteration within a meta-sedimentary sequence before going into a footwall intrusion. Significant intercepts include: TIGERC003: 12m @ 3.6% Zn, 0.5% Cu, 0.4% Pb, 13.4g/t Ag, and 0.1g/t Au from 31m incl. 6m @ 5.4% Zn, 0.6% Cu, 0.3% Pb, 16.6g/t Ag from 32m incl. 2m @ 5.6% Zn, 1.1% Cu, 0.3% Pb, 11.7g/t Ag from 35m and 6m @ 1.4% Zn, 0.4% Cu, 0.9% Pb, 11.5g/t Ag, and 0.2g/t Au from 18m TIGERC002: 9m @ 1.4% Zn, 0.3% Cu, 0.3% Pb, 11.5g/t Ag, and 0.1g/t Au from 31m incl. 1m @ 3.3% Zn, 0.8% Cu, 0.9% Pb, 31.0g/t Ag, and 0.3g/t Au from 32m and 2m @ 3.7% Zn, 0.5% Cu, 0.6% Pb, 23.3g/t Ag, and 0.3g/t Au from 37m TIGERC005:2m @ 2.0% Zn, 0.2% Cu, 0.8% Pb, 32.5g/t Ag and 0.3g/t Au from 54m In addition to the to the Cu-Au-Zn-Ag mineralisation, significant W-Ag-Au mineralisation was also intersected including: TIGERC001:1m @ 0.3% WO3, 31.8g/t Ag and 0.8g/t Au from 26m Sulphide species also generally showed a distinct zonation with a core of mixed sphalerite, chalcopyrite and galena with more chalcopyrite-rich possible stringer zones and more distal sphalerite-galena mineralisation in some holes. Mineralisation is interpreted to have a westerly plunge and remains open in all directions. Downhole geophysical surveys have identified 5 off-hole conductors with coincident DHMMR anomalism consistent with massive sulphide mineralisation. These off-hole conductors are compelling and follow up drilling will commence in September 2024. This program is supported by a cofunding EIS grant of up to $150,000 and a drill for equity agreement with Topdrill Pty Ltd.

The project has outcropping mineralisation and historical workings which have seen no modern exploration. Results to date indicate that there may be a related, large scale, Proterozoic Cu-Au VMS system at Tarraji-Yampi, similar to DeGrussa and Monty in the Bryah Basin. Mangaroon Ni-Cu-Co-3PGE, Au & REE Project (100%) Mangaroon covers ~5,300kms2 and is located 250kms south-east of Exmouth in the Gascoyne Region of WA. At the Money Intrusion, Ni-Cu-Co-3PGE has been identified. Dreadnought also has areas of outcropping high-grade gold including the historic Star of Mangaroon and Diamond gold mines. In addition, Mangaroon has emerged as a globally significant, rapidly growing, potential source of critical minerals. Highlights include: • An Exploration Target estimated for the top 150m of ~40km of the Yin REE Ironstone Complex (ASX 13 Feb 2023). • An independent Resource for Yin Ironstones Complex of 29.98Mt @ 1.04% TREO over only ~4.6kms – including a Measured and Indicated Resource of 26.3Mt @ 1.04% TREO (ASX 30 Nov 2023). • Regional source of rare earths at the Gifford Creek Carbonatite totaling ~17kms x ~1km (ASX 7 Aug 2023). • A large, independent initial Resource of 10.84Mt @ 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). Central Yilgarn Gold, Base Metals, Critical Minerals & Iron Ore Project (100%) Central Yilgarn is located ~190km northwest of Kalgoorlie in the Yilgarn Craton. The project comprises ~1,400kms2 covering ~150km of strike along the majority of the Illaara, Yerilgee, South Elvire and Evanston greenstone belts. Central Yilgarn is prospective for typical Archean mesothermal lode gold deposits, VMS base metals, komatiitehosted nickel sulphides and critical metals including Lithium-Cesium-Tantalum. Prior to consolidation by Dreadnought, the Central Yilgarn was predominantly held by iron ore explorers and remains highly prospective for iron ore. Bresnahan HREE-Au-U Project (100%) Bresnahan is located ~125km southwest of Newman in the Ashburton Basin. The project comprises ~3,700kms2 covering over 200kms strike along the Bresnahan Basin / Wyloo Group unconformity. Bresnahan is prospective for unconformity related heavy rare earth (“HREE”) deposits similar to Browns Range HREE deposits, unconformity uranium (“U”) deposits and mesothermal lode gold similar to Paulsens Au-Ag-Sb deposits along strike. Prior to consolidation by Dreadnought, the Bresnahan Basin had been successfully explored for unconformity uranium with limited exploration for mesothermal gold. Bresnahan is a first mover opportunity to explore for unconformity HREE. dreadnoughtresources.com.au 7 ASX:DRE +61 (08) 9473 8345 info@dreres.com.au Unit 1, 4 Burgay Court Osborne Park WA 6017 ABN 40 119 031 864 Hole ID TIGERC001 and TIGERC002 incl and and and and and TIGERC003 and and incl incl TIGERC004 and and TIGERC005 and TIGERC007 and Hole ID TIGERC001 TIGERC002 TIGERC003 TIGERC004 TIGERC005 TIGERC006 TIGERC007 TIGERC008 Table 3: Significant Results (>0.2% Zn, Cu, Pb, WO3 >0.2g/t Au) From To Interval Zn Cu Pb Ag Au WO3 (m) (m) (m) (%) (%) (%) (g/t) (g/t) (%) 26 27 1 0.2 0.2 0.5 31.8 0.8 0.3 56 59 3 1.0 0.1 0.3 12.0 31 40 9 1.4 0.3 0.3 11.5 0.1 32 33 1 3.3 0.8 0.9 31.0 0.3 37 39 2 3.7 0.5 0.6 23.3 0.3 82 84 2 0.2 0.3 14.5 0.1 90 91 1 0.2 0.3 18.3 93 95 2 0.2 0.2 13.2 139 141 2 0.3 0.1 7.8 0.1 13 15 2 0.3 3.2 0.2 18 24 6 1.4 0.4 0.9 11.5 0.2 31 43 12 3.6 0.5 0.4 13.4 0.1 32 38 6 5.4 0.6 0.3 16.6 35 37 2 5.6 1.1 0.3 11.7 70 71 1 0.8 0.1 2.7 86 87 1 0.4 0.1 0.1 5.8 46 52 6 0.2 54 56 2 2.0 0.2 0.8 32.5 0.3 61 62 1 0.8 3.3 91 93 2 0.2 0.1 0.3 9.5 98 100 2 0.2 Easting 370224 370312 370390 370493 370646 370633 370224 370393 Table 4: Drill Collar Data (GDA94 MGAz50) Northing RL Dip Azimuth EOH 7360081 295 -60 1 150 7360079 314 -60 0 150 7360072 299 -60 356 150 7360063 286 -61 0 150 7359992 286 -61 1 150 7359943 285 -61 0 250 7360036 285 -61 4 210 7360025 288 -61 2 246 Prospect Tiger Type RC RC RC RC RC RC RC RC Prospect Tiger JORC Code, 2012 Edition – Table 1 Report Template Section 1 Sampling Techniques and Data (Criteria in this section apply to all succeeding sections.) Criteria JORC Code explanation Commentary Sampling techniques • Reverse Circulation (RC) drilling was undertaken to produce samples for assaying. • • • 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. dreadnoughtresources.com.au Laboratory Analysis Two sampling techniques were utilised for this program, 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 subsampled 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. 8 ASX:DRE +61 (08) 9473 8345 info@dreres.com.au Unit 1, 4 Burgay Court Osborne Park WA 6017 ABN 40 119 031 864 Criteria JORC Code explanation Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information. Commentary 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. Suspected mineralisation at Tiger is submitted for Fire Assay from crushed sample (ALS Method Au-ICP22). All 1m samples are also submitted for 48 multi-elements via 4 acid digestion with MS/ICP finish (ALS Code ME-MS61). 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 sample recovery • • • • 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.). 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 Topdrill undertook the program utilising a truck mounted Schramm T685WS drill rig with additional air from an auxiliary compressor and booster. Bit size was 5 ½ ”. 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. At this stage, no known bias occurs between sample recovery and grade. 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. Core (or costean, channel, etc.) photography. The total length and percentage of the relevant intersections logged. RC Drilling RC chips were logged by a qualified geologist with sufficient experience in this geological terrane and relevant styles of mineralisation using an industry standard logging system which could eventually be utilised within a Mineral Resource Estimation. Lithology, mineralisation, alteration, veining, weathering and texture were all recorded digitally. Chips were washed each metre and stored in chip trays for preservation and future reference. RC pulp material is also analysed on the rig by pXRF and magnetic susceptibility meter to assist with logging and the identification of mineralisation. Logging is qualitative, quantitative or semi-quantitative in nature. Sub-sampling techniques and sample preparation • • • • • • If core, whether cut or sawn and whether quarter, half or all core taken. If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry. For all sample types, the nature, quality and appropriateness of the sample preparation technique. Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. Measures taken to ensure that the sampling is representative of the in-situ material collected, including for instance results for field duplicate/second-half sampling. Whether sample sizes are appropriate to the grain size of the material being sampled. RC Drilling From every metre drilled, a 2-3kg sample (split) was subsampled into a calico bag via a Metzke cone splitter. QAQC in the form of duplicates and CRM’s (OREAS Standards) were inserted through the ore zones at a rate of ≥1:50 samples. Additionally, within mineralised zones, a duplicate sample was taken and a blank inserted directly after. Tiger - 2-3kg samples are submitted to ALS laboratories (Perth), oven dried to 105°C, crushed to >90% passing 3mm, then pulverised to >90% passing 75µ to produce a 50g charge for determination of gold Fire Assay from crushed sample (ALS Method Au-ICP22). Additional material is then pulverised to 85% passing 75um to produce a 0.25g charge for determination of 48 multielements via 4 acid digestion with MS/ICP finish (ALS Code ME-MS61). Standard laboratory QAQC is undertaken and monitored.

Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. Specification of the grid system used. Quality and adequacy of topographic control. Collar positions have been reported here using a handheld garmin GPS (+/- 3m x/y, +/-10m z). Data spacing for reporting of Exploration Results. Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. Whether sample compositing has been applied. Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. The measures taken to ensure sample security. • • • Commentary instruments, etc., the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. The verification of significant intersections by either independent or alternative company personnel. The use of twinned holes. Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. Discuss any adjustment to assay data. ME-MS61 is considered a near total digest and is appropriate for base metals and pathfinder determination. Standard laboratory QAQC is undertaken and monitored by the laboratory and by the company upon assay result receival. Logging and Sampling Logging and sampling were recorded directly into a digital logging system, verified and eventually stored in an offsite database. Significant intersections are inspected by senior company personnel. No adjustments to any assay data have been undertaken. Collar position will be recorded using a Emlid Reach RS2 RTK GPS system (+/- 0.2m x/y, +/-0.5m z). GDA94 Z50s is the grid format for all xyz data reported. Azimuth and dip of the drill hole was recorded after the completion of the hole using a Axis Champ North-seeking Gyro. A reading was undertaken every 10th metre with an accuracy of +/- 0.75° azimuth and +/-0.15° dip. See table 4 hole positions and information. Drilling was undertaken at a near perpendicular angle to the interpreted strike and dip of the mineralised lodes. No sample bias is known at this time. All geochemical samples were collected, bagged, and sealed by Dreadnought staff and delivered t
