FOUR NEW RARE EARTH ELEMENT IRONSTONES DISCOVERED AT MANGAROON
HIGHLIGHTS
-
Four new Rare Earth Element (“REE”) ironstones have been discovered as part of the emerging Yin REE camp (Dreadnought 100%). Significant rock chips results include:
-
MNRK0407: 5.65% TREO, including 1.61% Nd2O3+Pr6O11
-
MNRK0399: 1.35% TREO, including 0.56% Nd2O3+Pr6O11
-
The new REE ironstones significantly increase the footprint of known REE mineralisation to ~11kms of strike.
-
A detailed airborne magnetic-radiometric survey will be flown in the December 2021 quarter over 50km strike extent which includes the six mineralised REE ironstones.
-
Importantly, Yin rock chips contain high neodymium and praseodymium (Nd2O3+Pr6O11) ratios of total rare earth oxides (“TREO”) of up to 43% and produce a potentially commercially treatable monazite concentrate.
-
The Yin REE camp is located ~5kms southwest of the Yangibana REE Project (“Yangibana”) which is currently under construction and development by Hastings Technology Metals Limited (ASX:HAS, “Hastings”).
Dreadnought Resources Limited (“ Dreadnought ”) is pleased to announce that it has received assays from recent rock chips that confirm four additional REE ironstones. This significantly expands the strike of the emerging Yin REE camp to ~11kms. The four newly identified prospects (Y3, Y4, Y5 and Y6) are visually and chemically similar to those seen at both Yin and Yangibana.
A detailed airborne magnetic and radiometric survey will commence later in September and is expected to highlight additional anomalies and allow for mapping under shallow cover to trace the ironstones. This work will assist in identifying new ironstone occurrences, and for the design of drill programs to commence in the March 2022 quarter.
Dreadnought’s Managing Director, Dean Tuck, commented: “ It is an exciting development confirming four new REE ironstones over ~11kms of strike which make Yin camp scale. We are excited for the results of the planned magnetic-radiometric survey to assist in further target generation ahead of Resource and discovery drilling in the March 2022 quarter.

Current Knowledge on REE at Yin (E09/2448, E09/2450, E09/2535: DRE 100%)
Mineralogy:
Yin, like Yangibana, is unique to REE deposits globally due to the high proportion of neodymium and praseodymium in the total rare earth oxides, with rock chips from Yin containing up to a 43% NdPr ratio (Nd2O3+Pr6O11 content of the TREO). As shown in the charts below, Nd2O3 and Pr6O11 account for ~90% of the relative value of the REE despite comprising ~31% of the TREO inventory. These charts have been based on the average of all REE ironstone rock chips collected to date across the Yin Camp.
==> picture [205 x 219] intentionally omitted <==
==> picture [208 x 218] intentionally omitted <==
Metallurgy:
One of the key matters to determine with REE projects is the ability to create a commercial product with economically recoverable REE. Dreadnought undertook early metallurgical test work to determine the amenability of the Yin ironstones to produce a commercially treatable monazite concentrate.
An initial flotation circuit using bulk surface samples from Yin performed well, achieving a recovery of 92.8% at a concentrate grade of 12.3% Nd2O3. and an average 40% TREO.
In addition, powder X-ray diffraction ( “XRD” ) confirmed the type of minerals hosting the REE at Yin to be predominantly monazite. Monazite is well-known to be amendable to commercial processing and as a source of REE at commercial scales.
Thorium and Uranium:
All REE deposits exhibit some degree of radioactivity, however, like Hastings’ Yangibana, data to date indicates that the Yin ironstones are very low in Th and U compared to other REE deposits.
| Yin | Yangibana | Nolan’s Bore | Dubbo | Mt Weld | Kvanfjeld | |
|---|---|---|---|---|---|---|
| Th(ppm) | 3141 | ~450 | ~2,700 | ~400 | ~700 | ~700 |
| U(ppm) | **101 ** | ~27 | ~200 | ~100 | ~20 | ~300 |

Rare Earth Element Strategy at Mangaroon (E09/2448, E09/2450, E09/2535: DRE 100%)
Work to date at Yin has confirmed encouraging REE grades, mineralogy and amenability to concentration by simple flotation. Furthermore, a high NdPr monazite concentrate may be attractive for processing by a number of facilities in Australia or overseas.
Dreadnought is now committed to commence Resource and discovery drilling at the Yin REE camp.
A modern, high resolution airborne magnetic-radiometric survey will be flown in September 2021 with results by November 2021. Drilling is expected to commence in the March 2022 quarter. This drilling will form the basis for a planned maiden JORC 2012 Resource in the June 2022 quarter.
Ongoing and Upcoming Work Programs at Mangaroon:
Ongoing: Mapping and rock chipping along the Money Intrusion for Ni-Cu-PGE target generation
Commenced: Project wide multi-element stream sediment sampling
Commenced: Petrological and mineralogical analysis of rocks from Yin
September: Fixed Loop EM Surveys along the Money Intrusion for Ni-Cu-PGE target definition
September/October: Detailed airborne magnetic-radiometric survey over REE ironstones

Rare Earth Elements at Mangaroon (E09/2448, E09/2450, E09/2535: DRE 100%)
The Yangibana ironstones are readily accessible and located 5-20kms from the Cobra-Gifford Creek Road. The ironstones were first explored in 1972 for base metals. The REE potential of the ironstones was first assessed in 1985 and has seen substantial work by Hastings Technology Metals on the Yangibana ironstones north of the Lyons River Fault since 2011 (Figure 3).
Yangibana currently has a JORC 2012 Mineral Resource* of 27.42Mt @ 0.97% TREO with 0.33% Nd2O3+Pr6O11 and is under construction and development. The high proportion of Nd2O3+Pr6O11 (used for electric vehicle magnets for and renewable power generation) are an important component of the project’s economics.
However, prior to Dreadnought, no significant REE exploration was undertaken south of the Lyons River Fault, which until now was considered to be the southern extent of the Yangibana REE Ironstones.
Recent TREO and Nd2O3+Pr6O11 results from Yin, exhibit similar characteristics to Yangibana and, to confirm this similarity, bulk samples were collected from outcrop for flotation test work and mineralogical analysis. The metallurgical assessment is an important first step in determining the potential for the TREO to be upgraded into a saleable intermediate product in the form of a concentrate. The mineralogical assessment is also important in that the beneficiation of monazite containing minerals to produce monazite concentrates is a demonstrated commercial scale process.
Significantly, six outcropping REE ironstones have now been identified, with detailed airborne magnetic-radiometric surveys to refine existing and additional targets. These surveys are to be conducted ahead of a drill program planned for Yin (initial JORC 2012 Resource definition) and any additional prospects (discovery).

Background on Mangaroon (E08/3274, E8/3178, E09/2384, E09/2433, E09/2473: Option with FQM) (E08/3275, E09/2370, E09/2448, E09/2449, E09/2450, E09/2467, E09/2478: 100%)
Mangaroon covers >4,500 sq. kms of the Mangaroon Zone in the Gascoyne Region of Western Australia. The region is host to high-grade gold mineralisation at the Bangemall/Cobra and Star of Mangaroon gold mining centres and the high-grade Yangibana REE deposits. During most of the region’s early history, there was no government support for prospecting and or exploration resulting in a vastly underexplored region in Western Australia.
Dreadnought has located outcropping high-grade gold bearing quartz veins along the Edmund and Minga Bar Faults, outcropping high tenor Ni-Cu-PGE blebby sulphides in the recently defined Money Intrusion and outcropping high-grade REE ironstones, similar to those under development at Yangibana. Mangaroon is still in the early stages with limited modern exploration.

About Rare Earths
REEs are comprised of fifteen elements that are “rare” in terms of the limited number of concentrated deposits.
Neodymium and praseodymium (Nd2O3 and Pr6O11) are classified as light rare earths and are used in steelmaking to remove impurities, as well as in the production of specialty alloys (including steel, chromium, magnesium, molybdenum, tungsten, vanadium and zirconium).
The use of REEs in magnets is rapidly increasing with neodymium-iron-boron magnets being the strongest known magnets and are used in applications such as electric motors for hybrid cars, wind turbines, high-tech military components and battery alloys.
China accounts for >90% of global REE supply and applies restrictions to this supply. Accordingly, REEs are critical metals because of the specialised use in modern technology combined with China’s near monopoly on supply. The political and economic issues surrounding global supply have highlighted the strategic importance of REEs.
Critical Minerals
Critical minerals are considered vital for the economic well-being of the world's economies, yet whose supply may be at risk due to geological, geopolitical or other factors. These minerals are used in the manufacture of mobile phones, flat screen monitors, wind turbines, electric cars, solar panels and many other high-tech applications.
The minerals ranked as most critical by the USA, Japan, South Korea, the UK and the European Union are as follows: rare-earth elements (REE), gallium (Ga), indium (In), tungsten (W), platinum-group elements (PGE), cobalt (Co), niobium (Nb), magnesium (Mg), molybdenum (Mo), antimony (Sb), lithium (Li), vanadium (V), nickel (Ni), tantalum (Ta), tellurium (Te), chromium (Cr), manganese (Mn) and bismuth (Bi).
Dreadnought’s critical minerals prospects include the following:
-
Illaara: Peggy Sue tantalum, niobium and lithium prospect
-
Mangaroon: Yin light rare earths and Lumpy’s Ni-Cu-PGE prospects
-
Tarraji-Yampi: Rough Triangle Cu-Sb-Bi-Ag, Texas and Orion Ni-Cu-PGE prospects

INVESTMENT HIGHLIGHTS
Kimberley Ni-Cu-Au Projects
Dreadnought controls the second largest land holding in the highly prospective West Kimberley region of WA. 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 1900s which have seen no modern exploration.
Three styles of mineralisation occur at Tarraji-Yampi including: volcanogenic massive sulphide (“ VMS ”); Proterozoic Cu-Au (“ IOCG ”); and magmatic sulphide Ni-Cu-PGE. Numerous high priority nickel, copper and gold drill targets have been identified from recent VTEM surveys, historical drilling and surface sampling of outcropping mineralisation.
==> picture [261 x 358] intentionally omitted <==
Mangaroon Ni-Cu-PGE, REE & Au Project
Mangaroon is a first mover opportunity covering ~4,500sq kms of tenure located 250kms south-east of Exmouth in the Gascoyne Region of Western Australia. During most of the regions early history, it did not receive government support for prospecting and or exploration resulting in a vastly underexplored region in Western Australia.
Since acquiring the project in late 2020, Dreadnought has located outcropping high-grade gold bearing quartz veins along the Edmund and Minga Bar Faults, outcropping high tenor Ni-Cu-PGE blebby sulphides in the recently defined Money Intrusion and outcropping high-grade REE ironstones, similar to those under development at the Yangibana REE Project. Mangaroon is still in the early stages with limited modern exploration.
Illaara Gold, VMS & Iron Ore Project
Illaara is located 190km northwest of Kalgoorlie in the Yilgarn Craton and covers 75kms of strike along the Illaara Greenstone Belt. Illaara is prospective for typical Archean mesothermal lode gold deposits and base metals VMS mineralisation.
Dreadnought has consolidated the Illaara Greenstone Belt mainly through an acquisition from Newmont. Newmont defined several camp-scale targets which were undrilled due to a change in corporate focus. Prior to Newmont, the Illaara Greenstone Belt was predominantly held by iron ore explorers and has seen minimal gold and base metal exploration since the 1990s.

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.
• 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.
