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 10 March 2026 RC Drilling Commenced at Metzke’s Find — Illaara Gold HIGHLIGHTS • A ~60-hole (~4,900m) RC drilling program has commenced at Metzke’s Find, part of the Illaara Gold Project (“Illaara”), with a focus on adding near-term production as part of Dreadnought’s Finding More Gold Faster strategy. • The drill program aims to: • Add ounces to the Resource along strike and at shallow depths; and • Upgrade even more of the Resource to the Indicated category • The 2023 Resource at Metzke’s Find currently consists of 14,900 oz @ 6.8 g/t Au (72% Indicated). Upon completion of the program, the Resource will be updated, upgraded and used to support studies. • The program will take ~4–6 weeks with assays expected in April and May 2026. Dreadnought Resources Ltd (“Dreadnought”) is pleased to announce the commencement of RC drilling at Metzke’s Find, part of the 100% owned Illaara Gold Project, in the Yilgarn region of WA. Dreadnought’s Managing Director, Dean Tuck, commented: “We now have two rigs at Illaara, an air core rig which is advancing our largest exploration drilling program to date, and now an RC rig focused on adding ounces to and upgrading the Metzke’s Find Resource. A key focus of our Finding More Gold Faster Strategy is to rapidly advance Metzke’s Find towards production. This drilling program will result in an updated Resource which will form the foundation of initial studies. We believe that our high-grade Metzke’s Find Resource is a great opportunity to expand production beyond the Star of Mangaroon. With two rigs, we look forward to a steady stream of news flow throughout the year from both Resource focused RC drilling and first pass air core drilling.” Figure 1: Image of the PXD RC rig drilling at Metzke’s Find.

In 2023, Dreadnought declared a shallow, high-grade Resource of 14,900 oz @ 6.8 g/t Au (72% Indicated). Historically, mineralisation was thought to terminate at a cross-cutting Proterozoic dyke located just north of the historic workings. Recent drilling has extended mineralisation by ~250m north of those workings with significant intercepts including MZRC103: 10m @ 1.5 g/t Au from 20m including 2m @ 5.8 g/t Au from 22m. The program of ~60-holes (~4,900m) aims to add to the Resource along strike and at shallow depths, and upgrade even more of the Resource to the Indicated category. Drilling will take ~4–6 weeks with assays expected in April and May 2026.

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 The mineralisation at Metzke’s Find comprises quartz lodes hosted within a foliated mafic sequence and typically dips steeply to the west. Discrete zones of mineralisation are high-grade, 1–4m in thickness and strike north-south with an interpreted moderate north plunge of around 30°. A total of 5 separate mineralised zones are interpreted, likely representing shoots developed within a single planar shear. 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.

Illaara is one of the most underexplored greenstone belts in the Yilgarn Craton and is situated nearby to 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.

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. Metzke’s Find – Indicated and Inferred Resources (ASX 27 April 2023) Table 2: Resource (0.5g/t Au cutoff grade) - Numbers may not add up due to rounding Type Indicated Inferred Total Tonnes Au (g/t) Au (Oz) Tonnes Au (g/t) Au (Oz) Tonnes Au (g/t) Au (Oz) Transition 800 1.1 30 1,100 17.4 600 1,900 10.3 600 Fresh 44,600 7.4 10,600 21,800 5.2 3,600 66,500 6.7 14,300 Total 45,00 7.3 10,700 22,900 5.8 4,200 68,400 6.8 14,900 Self-Funded Explorer Strategy – Pathway to Production • Dreadnought’s strategy is to transform into a self-funded explorer. 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 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, 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 @ 6.8g/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-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-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.
