Announcement PDF 20 June 2023 HIGHLY CONDUCTIVE ANOMALIES ENHANCE ORION LOOK-ALIKES – TARRAJI-YAMPI (80%/100%) HIGHLIGHTS • The high-grade Cu-Ag-Au-Co-Zn Orion discovery (~350m wide x ~150m long and modelled to at least 500m deep) was made in 2021. The Orion discovery was followed by extensive auger sampling programs in 2022 designed to geochemically “fingerprint” Orion and apply that knowledge across other under cover areas at Tarraji-Yampi. The auger program has now identified 14 high-quality Orion look-alikes to date with a similar geochemical signature (ASX 18 May 2023). • A Fixed Loop Electromagnetic (“FLEM”) survey has been completed to define conductive bodies associated with the geochemical anomalism. Of the 9 geochemical anomalies now surveyed, 6 have produced strong coincident conductors (3 with outcropping mineralisation) and 3 with moderate to weak conductors. • Discovery focused RC and diamond drilling is to commence in August / September 2023. Dreadnought Resources Limited (“Dreadnought”) is pleased to announce the results from the recently completed FLEM survey at Tarraji-Yampi, in the Kimberley Region of Western Australia. The FLEM survey has complimented the recently announced auger results that identified 14 high-quality targets with similar geochemical and geophysical signatures to Orion. Significantly, the combined results have identified 6 coincident geochemical, magnetic and strong conductor (>2,000S) anomalies, 3 of which have identified outcropping mineralisation. There are a further 3 moderate to weak conductors with coincident geochemical anomalies, including Thunderer North where an outcropping mineralised vein was identified with similarities to Grant’s Find and Vanguard. All targets sit within prospective lithostructural settings and will be RC drilled in August / September 2023. Dreadnought’s Managing Director, Dean Tuck, commented: “Tarraji-Yampi had been unexplored for over 50 years prior to becoming Dreadnought’s original flagship project upon listing in 2019. Since the Orion discovery in 2021, Dreadnought has significantly enhanced the geological, geochemical and geophysical understanding of this unexplored region. This has resulted in fourteen geochemical and geophysical anomalies, hosted within prospective lithostructural settings similar to the known massive sulphide mineralisation at Orion and vein hosted mineralisation at Grant’s. With our new understandings and datasets now available, it is worth highlighting that several of these anomalies are stronger, larger and/or higher tenor than those over Orion. We are excited about the prospect of making additional discoveries and proving the scale of the Cu-Ag-Au-Co opportunity at Tarraji-Yampi.” Figure 1: SGC Niche Acquisitions team and Frontier Helicopters prepare to set up FLEM loops at Orion.

A benchmark auger program was conducted over Orion where the cover is only 1-5m thick. Pleasingly, the weathered saprolite material beneath the cover expressed a ~350m x ~150m geochemical anomaly with a peak value of ~1,400ppm Cu+Pb+Zn+As above the massive sulphide mineralisation. The implication of “fingerprinting” Orion being that a broader auger program over Tarraji-Yampi would identify Orion look-alikes. Results have been highly encouraging with 14 look-alikes identified highlighting the camp scale potential at Tarraji-Yampi. Orion Trend: First pass, 200m x 40m and 100m x 40m auger sampling over the 4km x 1km Orion trend has highlighted 9 targets (Ironclad, OR1-8) all with >10x background (~80ppm Cu+Pb+Zn+As) with similar lithostructural settings and geophysical signatures to Orion. Other Areas: Outside of the Orion trend, over a dozen prospective areas were prioritised for auger work based on their known mineralisation, magnetic anomalism and or interpreted lithostructural setting. Of these areas, 5 returned significant anomalism with Thunderer East, Thunderer West and Neptune also having similar lithostructural settings to Orion. Vanguard and Thunderer North are similar to and a possible extension of Grant’s Find (Cu-Au). Gossanous and mineralised outcrops: Pleasingly, 6 new gossanous and mineralised outcrops were identified at Ironclad, OR4, Vanguard, Thunderer North, East and West. The recent FLEM survey has resulted in 6 highly conductive bodies coincident with defined geochemical anomalism at Orion and Thunderer. In particular, the modelled conductors at OR2 (4,590S) and OR7 (4,200S) are stronger than the original Orion anomaly (4,146S) with similar geochemical and magnetic signatures. A further 3 weak to moderate conductors have been defined coincident with geochemical anomalism and outcropping mineralisation which are analogous to the Grant’s Find style of vein hosted mineralisation. Additional FLEM surveys are planned for OR1, OR5, OR6 and Neptune in August with IP surveys at Vanguard following a trial orientation at Grants. RC drilling of the 14 Orion look-alikes will commence in August / September 2023. Table 1: Description of 14 Orion look-alikes (GDA94 MGA z51).

The YSTA is the second largest defence reserve in Australia after Woomera in South Australia and was off limits to mineral exploration from 1978 to 2013. The only significant exploration undertaken in the area was by WMC Resources in 1958 and Australian Consolidated Minerals in 1972, with both parties exploring for copper. Since opening for exploration in 2013, Dreadnought has secured the largest ground holding within the YSTA and developed strong working relationships with both the Department of Defence and the Dambimangari People.

The main project area, Tarraji-Yampi, is located only 85kms from Derby and has been locked up as a Defence Reserve since 1978. Tarraji-Yampi presents a rare first mover opportunity with known outcropping mineralisation and historic workings from the early 1900’s which have seen no modern exploration. Results to date indicate that there may be a related, large scale, Proterozoic Cu-Au-Ag-Bi-Sb-Co system at Tarraji-Yampi, similar to Cloncurry / Mt Isa in Queensland and Tennant Creek in the Northern Territory. Mangaroon Ni-Cu-PGE JV & REE Au 100% Project Mangaroon is a first mover opportunity covering ~5,300 kms located 250kms south-east of Exmouth in the vastly underexplored Gascoyne Region of WA. Part of the project is targeting Ni-Cu-PGE and is subject to a joint venture with First Quantum Minerals (earning up to 70%). The joint venture area contains outcropping high tenor Ni-Cu-PGE blebby sulphides at the Money Intrusion. Dreadnought’s 100% owned areas contain outcropping high-grade gold bearing quartz veins including the historic Star of Mangaroon and Diamond’s gold mines, along the Edmund and Minga Bar Faults and outcropping high-grade REE ironstones and seven carbonatite intrusions which may be the source of the region’s rare earth mineralisation. Dreadnought has delivered an initial JORC Inferred Resource over just 3kms of the Yin REE Ironstone Complex delivering 14.36Mt @ 1.13% TREO (30% NdPr:TREO Ratio) (ASX 28 Dec 2022) with an additional 40 strike kilometres still to be tested. Bresnahan HREE and Au Project Bresnahan is located ~125km southwest of Newman in the Ashburton Basin. The project comprises ~3,700 sq kms 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 and mesothermal lode gold similar to Paulsen’s Au-Ag-Sb deposits along strike. Prior to consolidation by Dreadnought, the Bresnahan Basin had only been explored for unconformity uranium with limited exploration for mesothermal gold. Bresnahan is a first mover opportunity to explore for unconformity HREE. Central Yilgarn Gold, Base Metals, Critical Minerals & Iron Ore Project Central Yilgarn is located ~190km northwest of Kalgoorlie in the Yilgarn Craton. The project comprises ~1,600 sq kms covering ~150km of strike along the majority of the Illaara, Yerilgee and Evanston greenstone belts. Central Yilgarn is prospective for typical Archean mesothermal lode gold deposits, VMS base metals, komatiite hosted nickel sulphides and critical metals including Lithium-Caesium-Tantalum. Prior to consolidation by Dreadnought, the Central Yilgarn was predominantly held by iron ore explorers and remains highly prospective for iron ore.

Criteria Sampling techniques JORC Code explanation • • • • 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. Commentary FLEM Survey Fixed Loop EM (FLEM) surveyed at 25m and 50m station spacing with 50m and 100m spaced lines. FLEM stations were planned perpendicular to geological strike of target horizons. Auger Soils Soil auger sampling was undertaken to produce samples for assaying. For the purposes of this program, auger is considered a surface sampling technique and not a drilling technique. ~500 grams of material was collected from the end of hole auger spoils (holes are between 1 and 9m deep) and placed into prenumbered plastic bags. All samples were submitted to ALS Laboratories in Perth and pulverised to produce a 0.5g charge for determination of 53 elements by an aqua regia digest and ICP-MS finish (ALS Code ME-MS41L). Samples were backfilled on completion of each hole to ensure minimal disturbance and evidence of drilling. Rock Chips Rock Chips were collected by Dreadnought staff and submitted for analysis. Rock chips are random, subject to bias and often unrepresentative for the typical widths required for economic consideration. They are by nature difficult to duplicate with any acceptable form of precision or accuracy. Rock chips have been collected by Dreadnought to assist in characterising different lithologies, alterations and expressions of mineralisation. In many instances, several rock chips were collected from a single location to assist with characterising and understanding the different lithologies, alterations and expressions of mineralisation present at the locality. Rock chips were submitted to ALS Laboratories in Perth for determination of Au, Pt and Pd by PGMICP24 and multiple (48) elements by ME-MS61 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 Auger Sampling OzEx undertook the program utilising a CF moto 1000cc UTV towing a custom built heli-portable auger rig mounted on a trailer and a second auger rig mounted on a Toyota Landcruiser.

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. Auger Sampling Auger sample recoveries are considered to be near 100%. There is potential for contamination from bringing the sample to surface, however assays are used as indicative values and not to be used for any resource studies. Auger sampling was undertaken using a ‘best practice’ approach to achieve maximum sample recovery and quality. Best practice sampling procedure included a shovel and trowel to separate material based on colour and geological changes downhole and every 1.5m rod, cleaning of sampling equipment every hole and suitable supervision by supervising DRE geologist to ensure good sample quality and the sampling of the correct material. At the end of each hole the auger is cleaned and suitable supervision by the supervising geologist to ensure good sample quality. At this stage, no known bias occurs between sample recovery and grade.

Duplicate samples were taken every 50 holes, whereby a second auger sample was completed ~1m from the original auger location and sampled to the same depth. All QAQC performed to an acceptable standard. Rock Chips All samples were submitted to ALS Laboratories in Perth where 1-3kg rock chips samples were crushed so that >70% of material passes through 6mm, the sample is then pulverised to >85% passing 75 micron. A 50 gram aliquot was analysed for Au, Pt and Pd by Fire Assay and ICP-AES finish (ALS Code PGMICP24) Fire Assay is considered a total digest for Au, Pt and Pd. A 0.25 grams aliquot was analysed for 48 elements by a four-acid digest and ICP-MS finish (ALS Code ME-MS61). Four-acid digest is considered a “near-total” digest for most elements. No standards, duplicates or blanks submitted with rock chips. Verification of sampling and assaying • • • • 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.
