RARE EARTHS, PHOSPHATE, NIOBIUM & ZIRCONIUM RESULTS FROM MANGAROON (DRE 100%)
HIGHLIGHTS
-
Two of six carbonatites (C3 and C4) confirmed as mineralised in rare earth elements (“REE”) and phosphate. C1, C2, C5 and C6 remain to be tested. Significant total rare earth oxides (“TREO”), neodymium-praseodymium (“Nd2O3+Pr6O11”) and phosphate rock chips included:
-
MNRK0545: 2.52% TREO (0.65% Nd2O3+Pr6O11) • MNRK0547: 1.98% TREO (0.59% Nd2O3+Pr6O11)
-
MNRK0542: 15.5% P2O5 and 0.72% TREO
-
High-grade ironstones (REE, niobium (“Nb2O5”) and zirconium (“ZrO2”)) identified around Y2 and Y3. Significant rock chips include:
-
MNRK0529: 39.7% TREO (6.30% Nd2O3+Pr6O11) • MNRK0573: 5.67% TREO (1.67% Nd2O3+Pr6O11)
-
MNRK0528: 15.2% Nb2O5, 21.5% ZrO2 • MNRK0526: 12.9% Nb2O5 and 0.67% TREO
-
Results support the geological model where the mineralised carbonatite intrusions may represent the source of the regional REE and associated mineralisation.
-
Potential carbonatite C6 interpreted from large undercover ~2km x 1.5km ovoid magnetic feature located between the Minga Bar and Minnie Creek Faults, which are major structural splays off the crustal scale Lyons River Fault.
Dreadnought Resources Limited (“ Dreadnought ”) is pleased to announce rock chip assay results from Mangaroon in the Gascoyne region of Western Australia (DRE 100%).
These results have confirmed REE and phosphate mineralisation within the C3 and C4 carbonatites. Additional high-grade ironstones containing REE, niobium and zircon have also been identified and support a geological model where the large-scale mineralised carbonatite intrusions may represent the source of the regional REE and associated mineralisation.
==> picture [257 x 291] intentionally omitted <==
Dreadnought’s Managing Director, Dean Tuck, commented: “Our geological model is that the large scale C1-C6 carbonatites may represent the source of REE mineralisation within the region. REE and niobium veins forming outwards from a central carbonatite core make for a textbook case. Phosphate is also another positive indicator as seen around the Mt Weld and other REE carbonatites. We expect to be drilling exciting targets along these large-scale carbonatites and ironstones commencing in March 2022.

Mangaroon Carbonatites C1-C5 (E09/2448: 100% DRE)
Dreadnought's recently flown airborne magnetic survey has highlighted five ovoid features (Figure 5) interpreted as igneous carbonatite intrusions. The intrusions range in size from 1,000m x 1,000m to 800m x 500m in dimension with internal ringing and a magnetic, possibly fenite alteration, halo around the perimeter of the intrusions. Over 99% of the interpreted carbonatite intrusions are obscured by a calcrete and alluvial plain with rare outcrop.
Rock chip samples were recently collected from the few outcrops within C3 and C4 with assays and XRD analysis confirming REE and phosphate mineralised carbonatites. Significant results include:
-
MNRK0545: 2.52% TREO (0.65% Nd2O3+Pr6O11) • MNRK0547: 1.98% TREO (0.59% Nd2O3+Pr6O11)
-
MNRK0542: 15.5% P2O5 and 0.72% TREO
XRD analysis has identified dolomite, microcline, and clinopyroxene, likely aegirine, confirming dolomitic carbonatites.
The intrusions are central to all known REE and niobium bearing ironstone dykes, fitting the classical carbonatite intrusion model. Recent ground truthing by Dreadnought has confirmed the presence of intrusive carbonatite within these features.
Outcrops sampled consisted of both fresh and weathered carbonatites with both rock types returning REE and phosphate mineralisation with higher grades coming from weathered carbonatites, which is similar to the mineralisation at Mt Weld in Western Australia and Araxa in Brazil.
The carbonatites remain largely obscured under calcrete cover. Systematic RC drilling will be undertaken at C1-C5 in April 2022. This program will identify areas of mineralisation under cover and help improve the understanding of this obscured and newly discovered system.

Mangaroon Carbonatite C6 (E09/2448: 100% DRE)
C6 is another potential carbonatite intrusion located between the Minnie Creek and Minga Bar Faults, structural splays linked with the crustal scale Lyons River Fault which is the interpreted conduit for carbonatite intrusions. C6 occurs ~25kms south of the C1-C5 carbonatites. C6 is defined by a large ovoid magnetic feature ~2km x 1.5km. The entire magnetic feature is under cover and drilling is required to confirm the lithology and presence of mineralisation.
Immediately to the northwest of C6 is an intense 900m x 600m magnetic feature which has been confirmed
==> picture [334 x 262] intentionally omitted <==
as an outcropping orthocumulate ultramafic intrusion. Ultramafic intrusions are known to occur associated with carbonatite intrusions and this could be part of the wider system.
C6 will be tested as part of the April 2022 drill program to confirm lithology and test for mineralisation. Geochemical and possibly geophysical work will also be undertaken on the ultramafic intrusion to assess the potential for Ni-Cu-PGE mineralisation. The base metal rights on E09/2448 remain 100% DRE.

Regional REE Carbonatite Model
The classic carbonatite model (Figure 1) envisions multiple pulses of carbonatites intrusions associated with radial or ring like dykes of REE and niobium bearing veins and widespread fenite alteration of the host rocks. These intrusions are nearly always associated with major crustal scale structures. Economic mineralisation is often concentrated within the carbonatite plugs (as primary magmatic, structural/vein hosted or residual enrichment) with additional minor mineralisation associated with the radial and ring dykes.
The Yangibana, Yin, Y2 and Y3 ironstones are weathered REE enriched dykes. Niobium rich veins have also been reported from drilling at Yangibana. Since 1991, explorers, geological surveys and academics have searched for the intrusive carbonatite sources that could explain the local proliferation of REE. These carbonatite intrusion sources have the potential to host significantly more mineralisation than the surrounding ironstones.
Previously, the carbonatite intrusions were believed to be blind and deep beneath the local REE ironstones as mineralisation was believed to have stopped at the Lyons River Fault – a major mantle tapping crustal scale structure.
The identification and confirmation of mineralised carbonatite intrusions has the potential to be a game changer for the region.

REE ironstones and Nb-bearing veins 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.
Mapping and interpretation of the recently flown magnetic and radiometric survey has highlighted Yin, Y2 and Y3 and significant clusters of REE and niobium ironstones. Surface sampling undertaken at the end of 2021, utilising a recently flown magnetic and radiometric survey, has resulted in the highestgrade rock chip ( MNRK0529: 39.7% TREO (6.30% Nd2O3+Pr6O11) from Y3 and the identification and confirmation of high-grade niobium veins at both Y2 and Y3 with significant results including:
• MNRK0528: 15.2% Nb2O5, 21.5% ZrO2 • MNRK0526: 12.9% Nb2O5 and 0.67% TREO
Yin, Y2 and Y3 will be RC drill tested in April 2022 with an aim to deliver an initial JORC 2012 resource.

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 48% Nd2O3+Pr6O11 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.

Figure 8: Charts outlining the abundance of rare earth oxides in rock chips (L) and relative value of rare earth oxides in rock chips (R) based on the average of all REE ironstone rock chips collected across the Yin camp to date.
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. No test work has yet been undertaken on the recently discovered carbonatite intrusions.
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.
1Yin values are based on the average of all rock chips containing >0.1% TREO, and may not reflect eventual resource Th and U grades.

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-grade REE ironstones, similar to those under development at Yangibana, and outcropping high tenor Ni-Cu-PGE blebby sulphides in the recently defined Money Intrusion.

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 1900’s which have seen no modern exploration.
Results to date indicate that there may be a related, large scale, Proterozoic Cu-AuAg-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, REE & Au Project
==> picture [256 x 351] intentionally omitted <==
Mangaroon is a first mover opportunity covering ~4,500sq kms of tenure located 250kms south-east of Exmouth in the Gascoyne Region of WA. During the region’s early history, there was limited government support for exploration resulting in the region being vastly underexplored.
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.
Illaara Gold, Base Metals, Critical Minerals & 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, VMS base metals and critical metals including Lithium-Caesium-Tantalum.
Dreadnought has consolidated the Illaara Greenstone Belt mainly through an acquisition from Newmont. Prior to Newmont, the Illaara Greenstone Belt was predominantly held by iron ore explorers and remains highly prospective for iron ore.

Section 1 Sampling Techniques and Data
JORC TABLE 1
Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Sampling techniques |
• 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. |
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 Rare Earth Oxides by Lithium Borate Fusion XRF (ALS Method ME-XRF30). |
| 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 what method, etc.). |
No drilling undertaken |
| Drill sample recovery |
• 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. |
No drilling undertaken |
| 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. |
||
| 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. |
Rock Chips Entire rock chips were submitted to the lab for sample prep and analysis. |
| Quality of assay data and laboratory tests |
• The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. • For geophysical tools, spectrometers, handheld XRF 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. |
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 66-gram aliquot of pulverised sample is fused with 12:22 lithium borate flux containing an oxidizing agent, and poured to form a fused disk. The resultant disk is in then analysed by XRF spectrometry specifically for Rare Earths (ALS Method ME-XRF30) • Lithium borate fusion is considered a total digest and Method ME-XRF30 is appropriate for REE determination. • 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. |
Rock Chips • Rock chip and geological information is written in field books and coordinates and track data saved from hand held GPSs used in the field. • Dreadnought and/or FQM geologists have inspected and logged all rock chips. • Field data is entered into excel spreadsheets to be loaded into a database. |
| Location of data points |
• 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 thegrid system used. |
• All sample locations were recorded with a Garmin handheld GPS which has an accuracy of +/- 5m. • GDA94 MGAz50. |

| Data aggregation methods |
• In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually Material and should be stated. • Where aggregate intercepts incorporate short lengths of high-grade results and longer lengths of low-grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. • The assumptions used for any reporting of metal equivalent values should be clearly stated. |
No drilling undertaken |
| Relationship between mineralisation widths and intercept lengths |
• These relationships are particularly important in the reporting of Exploration Results. • If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. • If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (e.g. ‘down hole length, true width not known’). |
No drilling undertaken |
| Diagrams | • Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. |
• Refer to figures within this report. |
| Balanced reporting | • Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. |
• The accompanying document is a balanced report with a suitable cautionary note. |
| Other substantive exploration data |
• Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. |
• Suitable commentary of the geology encountered are given within the text of this document. |
| Further work | • The nature and scale of planned further work (e.g. tests for lateral extensions or depth extensions or large-scale step-out drilling). • Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. |
• Additional mapping, surface sampling followed by EM surveys • Environmental and Heritage Surveys • Drilling |
