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 15 December 2025 Initial Orion Cu-Au-Ag-Co Resource – Tarraji-Yampi HIGHLIGHTS • The Orion Cu-Au-Ag-Co deposit was discovered in 2021 and has since been confirmed as a pelitic-mafic or “Besshi-style” volcanogenic massive sulphide (“VMS”) systems, similar to Degrussa in Western Australia. This is a style of mineralisation that is known to occur in camps with multiple deposits. Orion is part of the Tarraji-Yampi project. • The initial, independent Inferred JORC 2012 Mineral Resource (”Resource”) delivers 1.17Mt @ 1.2% Cu, 1.0g/t Au and 0.06% Co containing 14,200t of Cu, 38,900oz of Au, 745,900oz of Ag and 650t of Co (Table 1).

Additionally, repeat lodes and further targets within this emerging VMS camp show promise for additional discoveries. • Next steps include metallurgical test work on diamond core and finalizing the bi-annual renewal of the Deed of Access with the Commonwealth. • Importantly, Tarraji-Yampi is located in the Commonwealth’s Northern Australia Infrastructure Facility (“NAIF”) zone and hosts critical minerals including copper and cobalt which are essential for the global energy transition, electronics, and defense. Critical minerals are key to the Commonwealth's transition to net zero, vital to Australia’s strategic interests, and have the potential to boost economic development, particularly in northern Australia. Dreadnought Resources Limited (“Dreadnought”) is pleased to announce an independent, initial Resource for Orion, part of the Tarraji-Yampi project, located in the Kimberley Region of WA. Dreadnought’s Managing Director, Dean Tuck, commented: “Since the 2021 Orion discovery, Dreadnought has pushed to understand the system and opportunity at Orion and the wider Tarraji-Yampi Project. The initial resource for Orion highlights the attractive copper and gold mix of the near surface massive sulphide mineralisation. The discovery of additional massive sulphide lenses within the project and extensions of Orion is a compelling proposition. Understanding that Orion is part of a pelitic-mafic or “Besshi-style” VMS system, a system that tends to produce multiple deposits, underscores the possibility of further discoveries in this newly defined and vastly underexplored area. Given the recent closure of the Koolan Island Iron Ore mine, Orion also represents a potentially significant economic contributor to the West Kimberley Region. We are proud to continue to have the support of the Dambimangari People and look forward to renewing our Deed of Access with the Commonwealth Government to continue exploration in 2026” Figure 1: Image of RC drilling at Orion.

The region is known to contain outcropping quartz copper-gold lodes that were mined for copper on a small scale in the early 1900s and explored briefly by WMC in 1958 and ACM in 1972. The area has lithostructural and geochemical similarities to pelitic-mafic or “Besshi-style” VMS systems such as Degrussa in Western Australia, Windy Craggy in Canada or the Matchless deposits in Namibia. Dreadnought and others signed Deeds of Access with the Commonwealth commencing in 2018. The area was opened to exploration under the Commonwealth’s concept of "co-existence" involving Aboriginal people, explorers/developers/miners. Since that time, Dreadnought has been applying modern exploration techniques and knowledge to discover mineralisation in this highly prospective area investing ~$10M in the region and delivering a number of significant outcomes. The Orion discovery in 2021 was the result of testing one of its first undercover geophysical targets and resulted in a significant intercept of: 12m @ 1.6% Cu, 31.7g/t Ag, 0.5g/t Au, 0.02% Co from 45m (KMRC017). This was quickly followed by additional drilling confirming mineralisation to be ~350m wide x ~150m long, modelled to at least 500m deep and open down dip. Significant intercepts include (ASX 15 Nov 2021): 16m @ 2.2% Cu, 38.7g/t Ag, 6.6g/t Au, 0.40% Co from 77m (KMRC022) 20m @ 1.4% Cu, 13.4g/t Ag, 0.5g/t Au, 0.03% Co from 3m (KMRC039) 12m @ 3.0% Cu, 21.4g/t Ag, 1.7g/t Au, 0.02% Co from 1m (KMRC047) Since 2022, Dreadnought has been focused on extending Orion at depth, finding additional Orion look-a-like targets and assessing the potential for epithermal or lode style Cu-Au mineralisation such as those at Grant’s Find. To date, Dreadnought has undertaken several geochemical and geophysical surveys and drilled 62 RC holes (8,868m) and 17 diamond holes (3,282m) resulting in the Orion Cu-Au-Ag-Co discovery and the following exploration outcomes: • Discovery of high-grade critical metal vein system at Rough Triangle with rock chips returning significant results including: (ASX: 27 Aug 2021) • 13.2% Cu, 197g/t Ag, 14.5% Sb and 1.6% Bi (KMRK0007) • 21.3% Cu, 291g/t Ag, 15.0% Sb and 3.1% Bi (KMRK0010) • Cu-Ag-Zn-Pb Massive Sulphides at Chianti (ASX: 2 Dec 2019) • 0.5m @ 1.9% Cu, 2.2% Zn, 1.0% Pb, 37.6g/t Au • Cu-Au-Co System at Grants Find (ASX: 25 Aug 2021) • 10m @ 2.3% Cu, 0.1g/t Au and 0.03% Co from 101m (KMRC016) • 3m @ 2.1% Cu, 0.4g/t Au and 0.08% Co from 105m (KMRC015) • Cu-Co mineralisation at OR1 (ASX: 27 Oct 2024) • 6m @ 1.2% Cu and 0.08% Co from 27m including 2m @ 2.0% Cu and 0.19% Co from 28m (KMDD006) • Cu-Au-Co System at Ironclad (ASX: 27 Marc 2024) • 1m @ 2.2% Cu, 0.4g/t Au and 0.83% Co from 24m (KMRC059) • Four potential VMS camps and over a dozen drill targets with geophysical and geochemical anomalism warranting further exploration.

Dreadnought first signed a Deed of Access for the YSTA in 2018 which is renewed bi- annually. Dreadnought is currently re-negotiating its Deed of Access with the Commonwealth. Dreadnought has commissioned a review resulting in an initial, independent Inferred Resource at Orion. This Resource highlights the significant copper, cobalt and gold potential at Orion and within Tarriji-Yampi.

Commentary on the relevant input parameters for the Resource process is contained at the end of this announcement. Location and Region The Orion Cu-Au-Ag-Co Resource is located within Tarraji-Yampi located ~850kms north-east of Derby, in the Kimberley region of WA. Derby is identified as one of WA's most disadvantaged regions, particularly within the West Kimberley, and has and would greatly benefit from the development of critical and other minerals at Tarraji-Yampi.

Tarraji-Yampi predominantly comprises tightly folded metasediments of the highly prospective Early Proterozoic Marboo Formation, tightly constrained by Late Proterozoic granites of the Paperbark Suite which are exposed in the margins of the project area. The Marboo Formation sediments (consisting of thinly bedded, metamorphosed mudstone, siltstone, and sandstone lithologies interpreted as a turbidite sequence) outcrop in the headwaters of local rivers and host the known Cu-Au-Ag-Co mineralisation. Orion represents a Proterozoic pelitic-mafic Cu-Au-Ag-Co VMS system with analogues including the DeGrussa and Monty VMS deposits in the Bryah Basin. Mineralisation Interpretation Mineralisation at Orion consists of Cu-Au-Ag-Co massive sulphides hosted within a talc and chlorite altered peperite unit at the lower contact of mafic flows and sills that were intruded into wet, unconsolidated sediments of the Marboo Formation during rifting. At Orion, the principal mineralised horizon consists of a quartzite unit, with a strike of roughly 025° dipping to the southeast at ~50°. The mineralised horizon is ~250m long, 1-20m wide and defined over a dip length of 200m. Sulphide mineralisation is dominantly comprised of pyrrhotite and chalcopyrite with lessor pyrite, sphalerite, galena and localized cobaltite, arsenopyrite and bismuth-tellurides. Petrographic analysis of drill chips and diamond core suggests the mineralisation at Orion is associated with chlorite, talc, amphibolite and carbonate alteration. Classic durchbewegung textures have also been identified supporting the primary VMS style of mineralisation. Gold has been observed as free grains up to 50 microns in size associated with arsenopyrite, cobaltite and bismuth-tellurides. Weathering at the deposit is limited to a zone of transitional material extending up to 30m below surface. The majority of the mineralisation is within fresh rock.

In total, 22 RC (2,580m), 9 diamond holes (1,634m) have been used to estimate the Resource. The drilling has resulted in a relatively even spread of intersections throughout the Resource at spacings of 40x40m with some broader spaced drilling to test down-dip extensions to 120m. All holes used in the Resource have been previously announced with the necessary collar and assay details provided. These holes are also shown in Tables 9 and 10. RC holes were drilled by Ausdrill with a 5¾-inch bit and face sampling hammer. RC holes are also drilled with some water injection at the bit for dust suppression and with the use of booster/auxiliary air when ground water is encountered. Diamond holes were drilled by Top Drill as orientated HQ for shallower and NQ size for deeper drill holes. Collar positions were recorded using an Emlid Reach RS2 RTK GPS system (+/- 0.2m x/y, +/-0.5m z). GDA94 Z51s is the grid format for all xyz data reported. Azimuth and dip of each RC drill hole were recorded by Ausdrill after the completion of the hole using a Reflex Sprint IQ Gyro. A reading was undertaken every 30th metre with an accuracy of +/- 1° azimuth and +/-0.3° dip. Azimuth and dip of the diamond drill holes were recorded by Topdrill after the completion of the hole using an Axis Champ North-seeking Gyro. A reading was undertaken every 10th metre with an accuracy of +/- 0.5° azimuth and +/-0.15° dip. Sampling and Subsampling Techniques For the Resource drilling, RC samples were collected in 1m intervals directly from the rig sampling system. From every 1m drilled, a 2-3kg sample (split) was sub-sampled into a calico bag via a Metzke cone splitter. All remaining spoil from the sampling system was collected in buckets and deposited in rows adjacent to the rig. Orientated diamond core samples were collected with a diamond drill rig drilling HQ or NQ core. After geological logging and processing, the core was marked up for sampling at a typical minimum interval of 0.2m to ensure adequate sample weight and to a typical maximum interval of 1.0m. The selected sample intervals of drill core were cut in half or quartered along the length of the drill core. Sample sizes for both RC and diamond are considered appropriate for the style of mineralisation. Assaying and QAQC Samples were submitted to the ALS Perth laboratory for preparation and analysis of gold by fire assay and for 48 additional elements using a four-acid digest and ICP mass spectrometry. The 2-3kg samples were oven dried to 105°C and crushed to >85% passing 75um to produce a 50g charge for determination of gold by fire assay from crushed sample (ALS Method PGM-ICP24 or Au-ICP22) and to produce a 0.25g charge for determination of 48 multi- elements via 4 acid digestion with MS/ICP finish (ALS Code ME-MS61). QAQC in the form of duplicates and CRM’s (OREAS Standards) were inserted through the mineralised zones at a rate of 1:50 samples. Additionally, within mineralised zones, a duplicate sample was taken and a blank inserted directly after. Field duplicates (206) showed repeatable results with no bias evident. All OREAS standards (111) passed within the recommended control limits. Of the 113 blanks inserted within mineralised intervals, three contained minor (below cut off) contamination from two RC holes. A recognised laboratory was used for all assays which undertook standard laboratory QAQC. Overall, the QAQC returned satisfactory results and supports the assay data used in the Resource.

This was based on statistical analysis and visual examination of intersections suggesting a natural cut-off to the mineralisation of 0.3% Cu. The wireframes were used as hard boundaries to all grade estimation. The Resource was estimated using ordinary kriging (“OK”) grade interpolation of 1m composited data within the mineralisation wireframe. A high-grade cut of 15g/t was applied to gold. Zinc and lead mineralisation was also observed at Orion, but not modelled due to the focus on copper, cobalt and gold. Search ellipse parameters were based on the geometry of the mineralised zone and geostatistical parameters determined by variography. Up to three passes were used. The first pass had a search range of 50m with a minimum of 6 samples. For the second pass, the range was extended to 100m, with a minimum of 4 samples. The third pass had a range of 150m with a minimum of 2 samples. A maximum of 16 samples was used for all passes, with a maximum of 6 samples per hole. The block dimensions used in the model were 20m NS by 10m EW by 5m vertical with sub-cells of 1.25m x 1.25m x 1.25m. The parent block size is ~50% of the average drill hole spacing in the more intensely drilled part of the deposit. Density determinations were based on 151 measurements completed on rock core samples using the water displacement method as well as known values from similar geological terrains. The following bulk densities as tonnes per cubic metre were used: fresh high grade 3.85t/m3 , fresh mineralisation 3.10 t/m3 , fresh waste rock 2.86 t/m3 , transitional high grade 2.88 t/m3 , transitional mineralisation 2.70 t/m3 , transitional waste rock 2.58 t/m3 , transported surface material 1.8 t/m3 . Figure 8: Long section view showing the drill hole traces and grade distribution. Cut-off Grade, Metallurgy and Prospects for Economic Extraction The reporting cut-off grade of 0.5% Cu or 0.5g/t Au was derived considering the potential for open pit mining of the deposit. There is good potential for open pit mining of the upper portion of the deposit based on haulage to a milling facility or the discovery of additional mineralisation to justify a standalone operation. Metallurgical test work has not yet been conducted. Petrographic and mineralogical work has identified massive sulphides as predominantly medium grained (500um-1mm) with zones of finer grained (5-100um) base metal sulphides that should be amendable to standard flotation techniques. This test work will be undertaken as a part of future programs. Resource Classification Orion shows good continuity of the main mineralised units which allowed the drill hole intersections to be modelled into coherent, geologically robust domains. Consistency is evident in the thickness of the structures and the distribution of grade appears to be reasonable along and across strike. The Orion Resource was classified as Inferred based on data quality, sample spacing, and lode continuity in accordance with the 2012 Australasian Code for Reporting of Mineral Resources and Ore Reserves (“2012 JORC Code’). The Inferred Resource was assigned to the deposit based on 40m by 40m drill spacing, with some broader spaced drilling to test down-dip extensions to 120m.

Under this scenario, by 2030, supply from both existing and projected copper mines will meet just 80% of demand (S&P Global: The Future of Copper, July 2022). 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 11 Mangaroon Project Mangaroon covers ~5,000kms2 and is located 250kms south-east of Exmouth in the Gascoyne Region of WA. 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 23,400 oz Resource at 12.8g/t Au (84% 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 ~4.6kms – 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). 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 @ 6.8g/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-Co-Au-Sb Project (Tarraji 80% / Yampi 100%) Tarraji-Yampi covers ~420km2 is located only 85kms 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-Co-Au massive sulphides at Orion with results to date indicating a larg
