ASX ANNOUNCEMENT 25 October 2023
$180,000 DRILLING GRANT FOR MANGAROON REEs (100%)
HIGHLIGHTS
•
Dreadnought is pleased to advise that it has been awarded a co-funded drilling grant under the
Geological Survey of Western Australia’s merit-based Exploration Incentive Scheme (“EIS”) for
the Gifford Creek REE Carbonatite at Mangaroon (100%).
•
EIS grant of $180,000 for RC drilling to target gravity anomalies within the ~17km long Gifford
Creek Carbonatite and test for REE, niobium, titanium, phosphate and scandium mineralisation.
•
Dreadnought has received three EIS grants in 2023 totaling $620,000 to support drilling at the
Yin ironstones, the Gifford Creek Carbonatite (both at Mangaroon) and at Orion (TarrajiYampi).
•
The EIS grant for RC drilling at the Gifford Creek Carbonatite commences in December 2023,
therefore drill testing of the gravity anomalies will commence in 2024.
•
Results of the recently completed gravity survey over the Gifford Creek Carbonatite are
expected in November 2023. Drilling of the gravity anomalies will commence in March 2024.
Dreadnought Resources Limited (“Dreadnought”) is pleased to announce that it has been
awarded an EIS co-funded drilling grant at the 100% owned Mangaroon REE-Nb-P-Ti-Sc
project located in the Gascoyne Region of Western Australia.
EIS funding is managed by the Geological Survey of Western Australia (“GSWA") to stimulate exploration leading
to mineral discoveries. These grants are based on the technical merit of the drill target and Dreadnought was 1 of
36 successful applicants.
Dreadnought’s Managing Director, Dean Tuck, commented: “Dreadnought is very pleased to continue to receive support
from the EIS co-funded drilling program. The program is highly competitive, and the awarding of this grant further recognises
the technical merits and potential of the Gifford Creek Carbonatite to host significant rare earths and other critical metals. A
previous EIS grant funded the first holes into what has become the ~17km long Gifford Creek Carbonatite, the potential
source intrusions for the
Yin and Yangibana
ironstones. A lot has
been learned since
those first drill holes,
and we look forward to
delivering this program
with support of the
Geological Survey and
the State of Western
Australia.”

SNAPSHOT – MANGAROON RARE EARTHS
Mangaroon is 100% Owned by Dreadnought
Genuine Scale Potential Already at Yin REE Ironstone Complex
•
Independent Yin Inferred Resource of 20.06Mt @ 1.03% TREO (ASX 5 Jul 2023) covers only ~4km of ~43km of
strike with the initial Indicated Resource of 5.52Mt @ 1.23% TREO covering only ~250m of strike.
•
Exploration Target* of 50-100Mt at 0.9-1.3% TREO estimated for the top 150m of the Yin REE Ironstone
Complex (ASX 13 Feb 2023).
*This Exploration Target was first published by the Company on 13 February 2023. A copy of that announcement, containing the information underlying the
Exploration Target referred to above, is included in that announcement (refer to Annexure A). The Exploration Target has been prepared and reported in
accordance with the 2012 edition of the JORC Code. The potential quality and grade of the Exploration Target is conceptual in nature. There has been
insufficient exploration to estimate a Resource for all target areas reported. It is uncertain if further exploration will result in the estimation of a Resource. For
further understanding of the Exploration Target, refer to the announcement included in Annexure A.
Significant, Critical Minerals Potential at the Gifford Creek Carbonatite
•
Gifford Creek Carbonatite is considered to be the regional source of REE.
• In less than 12 months since the discovery of Gifford Creek Carbonatite, a large, independent Resource of
10.84Mt @ 1.00% TREO has been delivered. The Resource contains a range of critical minerals including rare
earths, niobium, phosphate, titanium and scandium.
•
The initial Resource covers an area of only ~600m x 550m. With the Gifford Creek Carbonatite now expanding
to ~17kms x 1km under wide-spaced, first pass drilling, it is expected that the Resource will grow substantially
with future drilling.
High-grade, Multi-Metal Potential Including REE (Neodymium, Praseodymium), Phosphate,
Niobium, Titanium & Scandium
•
The mineralisation at the Yin REE Ironstone Complex contains significantly higher NdPr as a fraction of the rare
earth oxides (“NdPr:TREO” ratio) than most other REE deposits globally, over 50% higher than the global
average.
•
Partially completed, first pass, wide spaced drilling over the Gifford Creek Carbonatite has identified significant
critical metal potential with REE, P, Nb, Ti and Sc.
Potentially Attractive Mining Proposition
•
At Yin, broad zones of flat to moderate dipping mineralisation with parallel lodes and Resource intensity of
~4.8Mt/km make for a potentially attractive mining proposition.
Positive Metallurgy Results
•
Metallurgical test work from Yin has performed well, achieving recoveries ranging from 85.9% to 92.8% at a
concentrate grade of 10.76% to 15.31% Nd2O3+Pr6O11.
•
REE at Yin is predominantly hosted in monazite which is amenable to commercial processing.
•
Significant metallurgical studies ongoing – results expected throughout 2023.
Global Strategic Imperative Driving Rare Earth Growth & Prices
•
Supply chain security and low carbon transition are imperatives against a backdrop of heightened geopolitical
tension.
•
Dreadnought is receiving increasing levels of interest from midstream and downstream industry participants in
Mangaroon. While the current focus is on upstream options (mining, milling and concentrating) opportunities
to collaborate with midstream and downstream industry participants may represent an opportunity.

INVESTMENT HIGHLIGHTS
Kimberley Ni-Cu-Au Project (80/100%)
The project 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 historic
workings 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 and Tennant
Creek.
Mangaroon Ni-Cu-PGE JV & Au/REE 100%
Project
Mangaroon covers ~5,200 kms and is located 250kms
south-east of Exmouth in the Gascoyne Region of WA.
At the Money Ni-Cu-PGE has been identified and is
subject to an earn-in by First Quantum Minerals (up to
70%). Dreadnought also has areas of outcropping highgrade gold including the historic Star of Mangaroon and
Diamonds gold mines. In addition, Mangaroon has
emerged as a globally significant, rapidly growing,
potential source of critical minerals. Highlights include:
-
An Exploration Target of 50-100Mt at 0.9-1.3%
TREO estimated for the top 150m of the ~43km
long Yin REE Ironstone Complex (ASX 13 Feb 2023).
-
An independent Resource for Yin Ironstones
Complex of 20.06Mt @ 1.03% TREO over only ~4kms – including an Indicated Resource of 5.52Mt @ 1.23%
TREO over just 250m strike (ASX 5 Jul 2023).
-
Regional source of rare earths at the Gifford Creek Carbonatite totaling >17kms x ~1km (ASX 7 Aug 2023).
-
A large, independent initial Resource of 10.84Mt @ 1.00% TREO, containing a range of critical minerals
including rare earths, niobium, phosphate, titanium and scandium (ASX 28 Aug 2023).
Bresnahan HREE and Au Project (100%)
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 (100%)
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.

ANNEXURE A
13 February 2023
REE IRONSTONE EXPLORATION TARGET DEFINED– MANGAROON (100%)
HIGHLIGHTS
• The substantial amount of geological knowledge derived from exploration and Resource work at the Yin and
Yangibana (ASX:HAS) ironstone complexes allows for robust interpretation of rare earth element (“REE”) ironstone
potential.
• The Yin Ironstone Complex is comprised of 43kms of REE mineralised ironstones which include:
• 3kms containing a JORC 2012 Mineral Resource (“Resource”) of 14.36Mt @ 1.13% TREO with a Resource
intensity of 4.8Mt/km (ASX 28 Dec 2022); and
• 40kms containing a JORC 2012 Exploration Target (“Exploration Target”) of 50-100Mt at 0.9-1.3% TREO with a
Resource intensity of 1.25-2.5Mt/km and a grade range of 1.13% TREO +/- 20%.
• The Exploration Target excludes potential ironstone mineralisation at >150m depth and mineralisation at the C1-C7
carbonatites.
• Mobilisation for the 2023 drilling campaign is underway with drilling expected to commence in February 2023.
Dreadnought Resources Limited (“Dreadnought”) is pleased to announce an Exploration Target for the ~40kms strike of
the Yin Ironstone Complex at the 100% owned Mangaroon project, located in the Gascoyne Region of Western Australia.
The recent expansion of the Yin Ironstone Complex to 43kms of strike, combined with extensive geological knowledge of
the REE ironstones in the region has provided the foundation for the Exploration Target. The Exploration Target covers
over 40kms of the near surface ironstones at Yin and importantly, excludes the current Yin Resource, any mineralisation
at depth (underground potential) and the C1-C7 carbonatites.
Systematic drilling to test the Yin Ironstone Complex has the potential to add significantly to the existing Resource.
Mobilisation for drilling at Yin and the C1-7 carbonatites is underway with drilling to commence in February 2023.
Dreadnought’s Managing Director, Dean Tuck, commented: “The
Exploration Target for the Yin Ironstone Complex is a fantastic
outcome reflecting the outstanding work undertaken by the
Dreadnought team over the past 18 months at Mangaroon. When
taken in the context that this estimation excludes the current
Resource at Yin and the mineralisation at the C1-C7 carbonatites the
opportunity for Mangaroon to become a globally significant REE
project cannot be underestimated.”
Cautionary Statement
The Exploration Target has been prepared and reported in
accordance with the 2012 edition of the JORC Code. The potential
quality and grade of the Exploration Target is conceptual in nature.
There has been insufficient exploration to estimate a Resource for all
target areas reported. It is uncertain if further exploration will result
in the estimation of a Resource.

SNAPSHOT - MANGAROON RARE EARTHS
Mangaroon is 100% Owned by Dreadnought
Genuine Scale Potential Already at Yin Ironstone Complex
• Initial independent Yin Inferred Resource of 14.36Mt @ 1.13% TREO (ASX 28 Dec 2022) covers only 3km of
43km of strike and is based on only 2.5 months of RC drilling (11,907m).
• Exploration Target of 50-100Mt at 0.9-1.3% TREO estimated for the top 150m of the Yin Ironstone
Complex.
• First tranche of long-term incentives now triggered with balance on track to be triggered at JORC
Resource of at least 30Mt @ >1% TREO by 31 December 2024.
Significant, Step-Change, Growth Potential Beyond Yin Ironstone Complex
• C1-C7 carbonatites are shaping up as the regional source of REE – initial drill program expands C1-C5 to
~6.5kms in strike length x 1km wide.
• C6 Carbonatite located ~25kms south of C1-5 and C7 is situated over a crustal scale structural splay of
the Lyons River Fault and has a geophysical similarity to other globally significant carbonatite intrusions
such as Mt Weld, Araxa and Ngualla
High-grade, Multi-Metal Potential Including REE (Neodymium, Praseodymium), Phosphorus, Niobium,
Titanium & Scandium (REE-P2O5-Nb2O5-TiO2-Sc)
• Yin, like the Yangibana REE project controlled by the ~$450M Hastings Technology Metals Ltd (ASX.HAS),
(“Hastings”) is globally unique due to the high proportion of NdPr as a total of the rare earth oxides
(“NdPr:TREO“ ratio).
• Six coherent zones of REE-P2O5-Nb2O5-TiO2-Sc successfully identified within the C1-C5 carbonatites with
a ~600m x 550m zone of REE-P2O5-Nb2O5-TiO2-Sc mineralisation now confirmed at the C3 discovery.
Potentially Attractive Mining Proposition
• Broad zones of shallow dipping mineralisation with parallel lodes and Resource intensity of ~4.8Mt/km
make for a potentially attractive mining proposition.
Positive Metallurgy Results
• Initial metallurgical test work from Yin performed well, achieving a recovery of 92.8% at a concentrate
grade of 12.3% Nd2O3 and an average 40% TREO.
• REE at Yin is predominantly hosted in monazite which is amenable to commercial processing.
• Significant metallurgical study from 16 diamond holes drilled at Yin underway – results expected
April/May 2023.
Analogous to a Globally Unique, Commercially Viable Development 25kms Away
• Yangibana is located only 25kms to the northeast of Yin and currently has a Resource* of 29.93Mt @
0.93% TREO with 0.32% Nd2O3+Pr6O11 (34% NdPr:TREO).
• Yangibana is under construction and development with first production planned for 2024.
Global Strategic Imperative Driving Rare Earth Growth & Prices
• Supply chain security and low carbon transition are imperatives against a backdrop of heightened
geopolitical tension.

Mangaroon REE Ironstones Exploration Target (E09/2448, E09/2450, E09/2535: DRE 100%)
The Yangibana 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 since 2011. The ~$450M Hastings controls the
Yangibana Ironstone Project and is Dreadnought’s immediate neighbour being to the north of the Lyons River Fault.
Yangibana (under construction) currently has a Resource of 29.93Mt @ 0.93% TREO (ASX:HAS 11 Oct 2022) and an
Exploration Target of 40-60Mt @ 0.7-1.0% TREO (ASX:HAS 15 Dec 2022). The Yangibana Resource is based off detailed
drilling covering 24kms of the identified 66kms (36%) of potential ironstones providing a Resource intensity of
1.25Mt/km. The Yangibana Exploration Target uses a Resource intensity of 0.6-0.9Mt/km to account for potentially
unmineralised portions and a grade range of +/- 20% to account for grade variation.
Over the past 18 months, Dreadnought has been exploring south of the Lyons River Fault resulting in the discovery
of the Yin Ironstone Complex and the C1-C7 carbonatites, the source intrusions for the region. A Resource of
14.36Mt @ 1.13% TREO (ASX:DRE 28 Dec 2022) has been defined based on detailed drilling over only 3kms of 43kms (7%)
of mineralised ironstones providing a Resource intensity of 4.8Mt/km, including unmineralised portions.
For the purposes of the Yin Exploration Target, geological information has been used from both Yangibana and Yin
to improve the robustness of the estimation whilst also reflecting the uniqueness of Yin in regards to its size and
grade.
The Exploration Target is based on a number of key assumptions including:
-
-
Tonnage of 50-100Mt: a Resource intensity of 1.25-2.5Mt/km reflecting the average of the wider Gifford Creek
Ferrocarbonatite Complex (1.25Mt/km – 40km x 1.25Mt = 50Mt) and the approximate midpoint between the
lower Yangibana Resource intensity of 0.6Mt/km and the current Yin Resource of 4.8Mt/km (2.5Mt/km – 40km
x 2.5Mt = 100Mt). This range is considered to be conservative given the extensive work in the region and the
significant Resource intensity already seen at Yin.
Grade of 0.9-1.3% TREO: the grade range was estimated using the existing Yin Resource grade of 1.13% +/20%.
The Exploration Target will be further refined through ongoing RC and diamond drilling commencing in February
2023.
The above Exploration Target process only considers the top 150m of the Yin Ironstone Complex. Given the
thickness and grades of Yin, internal assessment of the underground potential will be considered which may lead
to deeper drilling at Yin. Importantly, the Exploration Target excludes the C1-C7 carbonatites, the source intrusions
for the region.

Background on Mangaroon (E08/3274, E8/3178, E09/2384, E09/2433, E09/2473: FQM Earn-in)
(E08/3275, E09/2370, E09/2448, E09/2449, E09/2450, E09/2467, E09/2478: DRE 100%)
Mangaroon covers >5,300sq kms of the Mangaroon Zone in the Gascoyne Region of Western Australia.
Part of the project is targeting Ni-Cu-PGE and is subject to an earn in with First Quantum Minerals Ltd
(“FQM”) (earning up to 70%) – Figure 4. The region is host to high-grade gold mineralisation at the
Bangemall/Cobra and Star of Mangaroon gold mining centres and the high NdPr:TREO ratio Yangibana
REE deposits.
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, REE-Nb-Ti-P Carbonatites and outcropping high tenor Ni-Cu-PGE blebby sulphides in the
recently defined Money Intrusion.
In December 2022, Dreadnought delivered an initial independent Yin Resource of 14.36Mt @ 1.13%
TREO covering only 3kms of the 43kms of strike within the Yin REE Ironstone Complex.
