Dreadnought Resources Limited (“Dreadnought”) is pleased to announce results from
recent drilling at the Gifford Creek Carbonatite, part of the 100% owned Mangaroon Nb-REE
project, located in the Gascoyne Region of Western Australia.
Dreadnought’s Managing Director, Dean Tuck, commented: “The Gifford Creek Carbonatite has delivered the thickest
and highest-grade intercepts to date. All
this in a Tier 1 jurisdiction with ready
access to infrastructure including sealed
roads, ports, regional workforces and
airports. We continue to see the potential
for Mangaroon to evolve as a multicommodity critical metals hub with ready
access to existing infrastructure.”

Overview of Drilling Program: Nb-REE Gifford Creek Carbonatite
The Gifford Creek Carbonatite and the Yin Ironstones together form one of the largest alkali-carbonatite complexes in the
world (Figure 2). Carbonatite intrusions are known globally to host several different commodities including rare earths,
niobium, phosphate, titanium and scandium, often as separate deposits within the same intrusion. Examples of this include
Mt Weld in Australia, Ngualla in Tanzania, Araxa in Brazil and Bayan Obo in China.
Since the initial discovery of the Yin Ironstones and the Gifford Creek Carbonatite in 2021, Dreadnought’s focus has been
on rare earths. To date only ~25% of the Gifford Creek Carbonatite has been tested and then only with wide spaced first
pass drilling. Importantly, 3 zones of mineralisation have been confirmed (C3, Stinger and Rocky Road) with significant
niobium intercepts in the Stinger Zone, including:
CBRC176: 50m @ 0.9% Nb2O5 from 49m, including 20m @ 1.3% Nb2O5 from 56m
CBRC085: 48m @ 0.8% Nb2O5 from 30m, including 36m @ 1.0% Nb2O5 from 39m
CBRC111: 48m @ 0.7% Nb2O5 from 63m, including 9m @ 1.4% Nb2O5 from 72m
CBRC125: 59m @ 0.6% Nb2O5 from 63m, including 19m @ 1.0% Nb2O5 from 99m
CBRC138: 57m @ 0.6% Nb2O5 from 45m, including 3m @ 1.4% Nb2O5 from 90m
Recent mineralogical work has confirmed the presence of coarse grained (>0.30mm) pyrochlore niobium from both
weathered and fresh carbonatite. Pyrochlore niobium is commercially viable and accounts for ~95% of global niobium
production. Additional mineralogical work is ongoing with results expected in December 2024.

Recent drilling comprised 9 RC holes (1,508m) which were niobium focused and designed to:
-
Test for extensions of the Stinger oxide zone which contains thick intervals of niobium; and
-
Confirm the fresh rock source of the oxide mineralisation; and
-
Provide further material for mineralogical and metallurgical characterisation.
The program sought to confirm fresh mineralisation and extend oxide enriched mineralisation at Stinger. Stinger is defined
by niobium enrichment over an area of ~2,000m x 350m. Fresh niobium mineralisation is interpreted to be hosted in a dyke
like geometry with a southwest dip within the Gifford Creek Carbonatite, which has now been confirmed over ~1.2km in
strike.
Assays have been received for the 9 RC holes and all holes returned significant mineralisation, including the 4 thickest and
highest-grade intercepts to date. Intercepts include:
CBRC195: 130m @ 0.7% Nb2O5 from 71m, including:
39m @ 1.3% Nb2O5 from 84m including 4m @ 2.0% Nb2O5 from 86m
CBRC200: 95m @ 0.9% Nb2O5 from 48m, including
20m @ 1.4% Nb2O5 from 102m and 8m @ 1.7% Nb2O5 from 72m
CBRC194: 122m @ 0.7% Nb2O5 from 71m, including 26m @ 1.1% Nb2O5 from 99m
CBRC201: 98m @ 0.7% Nb2O5 from 54m, including 41m @ 1.1% Nb2O5 from 85m

CBRC196: 24m @ 0.7% Nb2O5 from 81m, including 8m @ 1.3% Nb2O5 from 81m
CBRC197: 28m @ 0.8% Nb2O5 from 66m, including 14m @ 1.0% Nb2O5 from 71m
This program has confirmed
fresh
mineralisation
over
~1.2km of strike which remains
open in all directions.
Next steps include wide spaced
fenceline drilling across the
Stinger Zone to better constrain
the oxide and fresh boundaries.
This work will also collect
material for mineralogical and
metallurgical assessment.
The program was supported by
a co-funded drilling grant of up
to
$180,000
under
the
Geological Survey of Western
Australia’s
merit-based
Exploration Incentive Scheme
(“EIS”) and a drill-for-equity
agreement with Topdrill Pty Ltd.

Zone providing significant upside tonnage potential.
Multiple Critical Minerals Potential at the Gifford Creek Carbonatite
•
The Gifford Creek Carbonatite and associated ironstones is one of the largest carbonatite complexes in the
world.
•
Wide spaced drilling over <25% of the ~17km long Gifford Creek Carbonatite has already identified 3 zones
of mineralisation containing Nb-REE-Sc-Ti-P. This makes for a critical mineral mix of co-products with
significant intercepts including:
CBRC115: 102m @ 1.1% TREO from 3m, including 29m @ 2.1% TREO from 76m
CBRC148: 43m @ 11.9% P2O5 from 87m, including 24m @ 14.5% P2O5 from 105m to EOH
CBRC138: 12m @ 319ppm Sc from 48m and CBRC125: 10m @ 270ppm Sc from 18m
CBRC086: 72m @ 8.6% TiO2 from 12m, including 6m @ 12.8% TiO2 from 66m
Positive Mineralogical Results
•
Recent mineralogical work at the Gifford Creek Carbonatite has confirmed the presence of pyrochlore,
which is a high niobium mineral (>50%) which is commercially viable and from which ~95% of global niobium
is produced.
Global Strategic Imperative Driving Critical Minerals Growth
•
Supply chain security and low carbon transition are imperatives against a backdrop of heightened geopolitical
tension.
•
Niobium is a critical mineral primarily used in high strength, low alloy steel with application to renewables,
infrastructure and vehicles. The addition of a small amount of niobium increases the strength of steel whilst
decreasing weight by ~30%.
•
Niobium-based technology breakthroughs are being experienced in the battery sector where niobium is
reducing electric vehicle charge times to ~5 minutes.

INVESTMENT HIGHLIGHTS
Mangaroon Au, Nb-REE, Ni-Cu-PGE Project (100%)
Mangaroon covers ~5,300kms2 and is located 250kms
south-east of Exmouth in the Gascoyne Region of WA.
At Mangaroon, Dreadnought has consolidated areas of
outcropping high-grade gold and historical high grade
gold mines including the historic Star of Mangaroon and
Diamond gold mines. Exploration at the Money Intrusion
has identified high tenor Ni-Cu-PGE sulphides. In
addition, Mangaroon has emerged as a globally
significant, rapidly growing, potential source of critical
minerals. Highlights include:
•
An independent Resource for Yin Ironstones
Complex of 29.98Mt @ 1.04% TREO 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-TiSc enriched Gifford Creek Carbonatite (ASX 7 Aug
2023).
•
A large, independent initial Resource of 10.84Mt @
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).
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 historical workings which have seen no modern exploration.
Results to date indicate that there may be a related, large scale, Proterozoic Cu-Au VMS system at Tarraji-Yampi,
similar to DeGrussa and Monty in the Bryah Basin.
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 ~1,400kms2
covering ~150km of strike along the majority of the Illaara, Yerilgee, South Elvire and Evanston greenstone belts.
Central Yilgarn is prospective for typical Archean mesothermal lode gold deposits, VMS base metals, komatiitehosted nickel sulphides and critical metals including Lithium-Cesium-Tantalum.
Prior to consolidation by Dreadnought, the Central Yilgarn was predominantly held by iron ore explorers and
remains highly prospective for iron ore.
Bresnahan HREE-Au-U Project (100%)
Bresnahan is located ~125km southwest of Newman in the Ashburton Basin. The project comprises ~3,700kms2
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, unconformity
uranium (“U”) deposits and mesothermal lode gold similar to Paulsens Au-Ag-Sb deposits along strike.
Prior to consolidation by Dreadnought, the Bresnahan Basin had been successfully explored for unconformity
uranium with limited exploration for mesothermal gold. Bresnahan is a first mover opportunity to explore for
unconformity HREE.

Commentary
Sampling techniques
•
Reverse Circulation (RC) drilling was undertaken to produce
samples for assaying.
•
•
•
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.
Laboratory Analysis
Two sampling techniques were utilised for this program, 1m
metre splits directly from the rig sampling system for each
metre and 3m composite sampling from spoil piles. Samples
submitted to the laboratory were determined by the site
geologist.
1m Splits
From every metre drilled a 2-3kg sample (split) was subsampled into a calico bag via a Metzke cone splitter from each
metre of drilling.
3m Composites
All remaining spoil from the sampling system was collected in
buckets from the sampling system and neatly deposited in
rows adjacent to the rig. An aluminium scoop was used to
then sub-sample each spoil pile to create a 2-3kg 3m
composite sample in a calico bag.
A pXRF is used on site to determine mineralised samples.
Mineralised intervals have the 1m split collected, while
unmineralised samples have 3m composites collected.
All samples are submitted to ALS Laboratories in Perth for
determination of Niobium and Rare Earth Oxides by Lithium
Borate Fusion and ICP-MS and ICP-AES (ALS Method MEMS81h and ME-ICP06h).
QAQC samples consisting of duplicates, blanks and CRM’s
(OREAS Standards) were inserted through the program at a
rate of 1:50 samples. Duplicate samples are submitted as a Bbag from the Metzke’s cone splitter.
Drilling techniques
Drill sample recovery
•
•
•
•
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.).
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.
RC Drilling
Topdrill undertook the program utilising a truck mounted
Schramm T685WS drill rig with additional air from an
auxiliary compressor and booster. Bit size was 5 ½ ”.
RC Drilling
Drilling was undertaken using a ‘best practice’ approach to
achieve maximum sample recovery and quality through the
mineralised zones.
Best practice sampling procedure included: suitable usage of
dust suppression, suitable shroud, lifting off bottom between
each metre, cleaning of sampling equipment, ensuring a dry
sample and suitable supervision by the supervising geologist
to ensure good sample quality.
At this stage, no known bias occurs between sample recovery
and grade.
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.
