ASX ANNOUNCEMENT 12 August 2024
Gifford Creek Niobium Drilling Update – Mangaroon (100%)
HIGHLIGHTS
-
A total of 19 RC holes (1,795m) have been completed at the newly named Stinger and Rocky Road niobium targets, part of the Gifford Creek Carbonatite (Figure 3).
-
Initial assay results are expected in August 2024, with planned follow-up drilling once assays are received.
-
Reconnaissance drilling has extended the Gifford Creek Carbonatite by 5km to the south. An aircore drill program is being planned for testing for oxide niobium enrichment within the extension (Figure 3).
-
RC drilling of the Tiger Cu-Au-Zn-Ag target has commenced. Drilling of other Mangaroon gold targets is to follow.
Dreadnought Resources Limited (“Dreadnought”) is pleased to announce that RC drilling has been completed at the Gifford Creek Carbonatite, part of the Mangaroon project, located in the Gascoyne Region of Western Australia.
Dreadnought’s Managing Director, Dean Tuck, commented: “ The Gifford Creek Carbonatite has produced some of WA’s best niobium intercepts outside the Arunta Province. With strong niobium identified across multiple zones, we see the potential for Mangaroon to evolve as a multi-commodity critical metals hub within proximity to existing infrastructure with mutual benefit to pastoralists, existing ports and neighboring projects. We look forward to receiving the assays from this program and designing follow up programs after our gold and base metal drilling, which is currently underway.”

SNAPSHOT – MANGAROON CRITICAL MINERALS
Mangaroon is 100% Owned
- 100% owned Mangaroon confirmed as a globally significant critical minerals complex with proven potential for rare earths (REE), niobium (Nb), scandium (Sc), titanium (Ti) and phosphorous (P).
Genuine Scale Potential Already at the Yin Ironstones
-
Independent Yin Resource of 29.98Mt @ 1.04% TREO (ASX 30 Nov 2023) covers only ~4.6km of ~43km of strike - 87% Measured and Indicated.
-
Yin contains a higher NdPr to total rare earth oxides (“ NdPr:TREO ”) ratio than most REE deposits and >50% higher than the global average.
Significant, Growth and 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 4 zones of mineralisation containing rare earths, niobium, scandium, phosphorous and titanium. This makes for a potential multi-critical mineral mix of co-products with significant intercepts including:
CBRC115: 102m @ 1.1% TREO from 3m, including 29m @ 2.1% TREO from 76m
CBRC085: 48m @ 0.8% Nb2O5 from 30m, including 36m @ 1.0% Nb2O5 from 39m
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 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.
-
ANSTO, a world-leader in the processing of critical and strategic metals, has demonstrated that the Yin monazite concentrate has excellent metallurgical recoveries using a conventional low-temperature acid bake/leach process and produces a high quality MREC containing 60.7% TREO (16.3% Nd2O3 and 4.4% Pr6O11) with ~94% recovery of Nd and Pr.
-
Recent mineralogical work at the Gifford Creek Carbonatite has confirmed that the dominant niobium mineral is pyrochlore, which is a high niobium mineral (>50%) 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 whose primary use is in HSLA (high strength, low alloy) steel with major applications in renewables, infrastructure and vehicles. The addition of a small amount of niobium increases the strength of steel whilst decreasing the weight required by almost 30%.
-
In addition to traditional applications in the steel industry, niobium-based technology breakthroughs are being experienced in the battery sector, where the adoption of niobium-based materials is reducing electric vehicle charge times to a mere 5 minutes.

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 with wide spaced first pass drilling. Importantly, 3 zones of mineralisation have been confirmed (C3, Stinger and Rocky Road) with significant niobium intercepts including:
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 CBRC110: 39m @ 0.6% Nb2O5 from 66m, including 3m @ 1.1% Nb2O5 from 81m 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 from both weathered and fresh magnesio-carbonatite.

The recent RC drilling program was niobium focused and designed to:
-
Test regional geophysical targets believed to be zones of deeper weathering or different phases of carbonatite;
-
Test for extensions of the Stinger target which contains thick intervals of pyrochlore Nb mineralisation; and
-
Provide further material for mineralogical and metallurgical characterisation.
A total of 19 RC holes (1,795m) have been drilled confirming and extending enriched carbonatite at the newly named Stinger and Rocky Road niobium targets. Stinger and Rocky Road are both defined by niobium enrichment in saprolite and fresh carbonatite over areas of ~2,000m x 350m (Stinger) and ~1,000 x 200m (Rocky Road). Fresh niobium mineralisation is interpreted to be hosted in a dyke like geometry with a southwest dip within the Gifford Creek Carbonatite, similar to Catalao II Complex in Brasil. Subject to assays, follow up drilling at these targets will consist of fence line drilling to test for oxide mineralisation and the source of the fresh mineralisation.
Initial assays are expected in August 2024. In addition, samples will be sent for mineralogical work.
This drill program is 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.
Reconnaissance drilling of geophysical targets has extended the Gifford Creek Carbonatite by 5km to the south. An aircore drill program is being planned to test for oxide niobium enrichment within the extension.

Tiger Cu-Au-Zn-Ag Prospect (100%)
Tiger is defined by a ~500m long subcropping gossanous horizon within a coincident ~900m x 300m Cu-Au-Zn-Ag and pathfinder-in-soil anomaly. Tiger contains some of the strongest Cu-Au-Zn-Ag rock chips and pathfinder anomalism defined to date at Mangaroon. The Cu-Au-Zn-Ag gossans appear to have formed after massive sulphides and given the strong pathfinder association, are considered to be related to VMS style mineralisation.
RC drilling (8 holes) has been designed to test the ~500m strike of subcropping mineralisation including 5 shallow holes and three deeper holes, which will also provide a platform for down hole EM (“DHEM”) surveys.
Drilling has commenced and is expected to be completed in August 2024. DHEM surveys will commence following the program. This drilling program is supported by an EIS grant of up to $150,000.
Results of this drilling and geophysical program are expected in September/October 2024.

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.
Mangaroon Ni-Cu-Co-3PGE, Au & REE Project (100%)
Mangaroon covers ~5,300kms[2] and is located 250kms south-east of Exmouth in the Gascoyne Region of WA. At the Money Intrusion, Ni-Cu-Co-3PGE has been identified. Dreadnought also has areas of outcropping high-grade gold including the historic Star of Mangaroon and Diamond gold mines. In addition, Mangaroon has emerged as a globally significant, rapidly growing, potential source of critical minerals. Highlights include:
-
An Exploration Target estimated for the top 150m of ~40km of the Yin REE Ironstone Complex (ASX 13 Feb 2023).
-
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).
-
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 at the Gifford Creek Carbonatites, containing a range of critical minerals including rare earths, niobium, phosphate, titanium and scandium (ASX 28 Aug 2023).
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 ~1,400kms[2] 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 ~3,700kms[2] 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.

Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
| Criteria | **JORC Code explanation ** | Commentary | 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. |
Reverse Circulation (RC) drilling was undertaken to produce samples for assaying. 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 sub- sampled 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 either ALS Laboratories in Perth for determination of Rare Earth Oxides by Lithium Borate Fusion XRF (ALS Method ME-XRF30) or Intertek Minerals in Perth for determination of Rare Earth Oxides by Lithium Borate Fusion XRF (Intertek Method FB6/OM45). All 1m samples are also submitted for 48 multi-elements via 4 acid digestion with MS/ICP finish (ALS Code ME-MS61 or Intertek Code 4A/MS48) to assist with lithological interpretation. Diamond Core Core is orientated for structural and geotechnical logging where possible.Inorientatedcore,halfcoreis submittedto |

| the lab for analysis in intervals ranging from 20cm to 1m depending on the geological context. If core is orientated, then the half core is cut so as to preserve the orientation line with the same side of the core submitted down the hole. All samples are submitted to ALS Laboratories in Perth for determination of Rare Earth Oxides by Lithium Borate Fusion XRF (ALS Method MEXRF30). Select samples are also submitted for 48 multielements via 4 acid digestion with MS/ICP finish (ALS Code ME-MS61) to assist with lithological interpretation. 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 quarter core or as a B-bag from the Metzke’s cone splitter. |
|||
| 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.). |
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 5¾”. Diamond Drilling Diamond drilling was undertaken by Hagstrom Drilling with a truck-mounted low impact diamond drill rig. Drilling is either HQ to end of hole or initially HQ and dropping to NQ once the hole is cased off for deeper drill holes. Core is orientated using a Reflex Sprint gyro and True Core Orientation Tool. |
|
| 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. |
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. Diamond Drilling HQ and NQ drilling has been undertaken. All core recoveries are measured and recorded by the drill crew for each run and remeasured and checked by Dreadnought personnel. Core recovery to date has been very high. At this stage, no known bias occurs between sample recovery andgrade. |
|
| 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. |
RC Drilling RC chips were logged by a qualified geologist with sufficient experience in this geological terrane and relevant styles of mineralisation using an industry standard logging system which could eventually be utilised within a Mineral Resource Estimation. Lithology, mineralisation, alteration, veining, weathering and texture were all recorded digitally. Chips were washed each metre and stored in chip trays for preservation and future reference. RC pulp material is also analysed on the rig by pXRF, scintillometer and magnetic susceptibility meter to assist with logging and the identification of mineralisation. Logging is qualitative, quantitative or semi-quantitative in nature.

• 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. |
RC Drilling From every metre drilled, a 2-3kg sample (split) was sub- sampled into a calico bag via a Metzke cone splitter. QAQC in the form of duplicates and CRM’s (OREAS Standards) were inserted through the ore zones at a rate of 1:50 samples. Additionally, within mineralised zones, a duplicate sample was taken and a blank inserted directly after. 2-3kg samples are submitted to ALS laboratories (Perth), oven dried to 105°C and pulverised to 85% passing 75um to produce a 0.66g charge for determination of Rare Earth Oxides by Lithium Borate Fusion XRF (ALS Method ME- XRF30) and to produce a 0.25g charge for determination of 48 multi-elements via 4 acid digestion with MS/ICP finish (ALS Code ME-MS61). Standard laboratory QAQC is undertaken and monitored. Diamond Drilling 20cm – 1m quarter core samples are sawn and submitted to the lab for analysis. If core is orientated, then the core is cut so as to preserve the orientation line with the same side of the core submitted down the hole. For the purposes of metallurgical testing, half core was submitted where possible to make the required bulk composite mass required for ongoing testwork. In some instances, this required full core to be used. QAQC in the form of duplicates, blanks and CRM’s (OREAS Standards) are inserted through the mineralised zones at a rate of 1:50 samples. Additionally, within each mineralised zone, a duplicate sample is taken and a blank inserted directly after. Samples are submitted to ALS laboratories (Perth), oven dried to 105°C and pulverised to 85% passing 75um to produce a 0.66g charge for determination of Rare Earth Oxides by Lithium Borate Fusion XRF (ALS Method ME- XRF30) and to produce a 0.25g charge for determination of 48 multi-elements via 4 acid digestion with MS/ICP finish (ALS Code ME-MS61). Standard laboratory QAQC is undertaken and monitored. |

| 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) andprecision have been established. |
Laboratory Analysis Lithium borate fusion is considered a total digest and Method ME-XRF30 and FB6/OM45 are appropriate for REE, P2O5, TiO2 determination. ME-MS61 and 4A/MS48 are considered a near total digest and is appropriate for Sc determination. Standard laboratory QAQC is undertaken and monitored by the laboratory and by the company upon assay result receival. |
|
| 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. |
Logging and Sampling Logging and sampling were recorded directly into a digital logging system, verified and eventually stored in an offsite database. Significant intersections are inspected by senior company personnel. 10 pairs of twinned RC and DD holes have been drilled at this time and compared to validate the RC drilling. No adjustments to any assay data have been undertaken. |

|
| Data spacing and distribution |
• Data spacing for reporting of Exploration Results. • Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. • Whether sample compositing has been applied. |
See table 1 hole positions and information. |
| Orientation of data in relation to geological structure |
• Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. • If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
Orientation of residual mineralisation is interpreted to be flat lying near the base of weathering for which vertical drill holes are generally perpendicular and represent truth thickness. Fresh mineralisation is interpreted to have a dyke like geometry with a southerly dip, based off the resource drilling at C3. Angled drill holes are interpreted to be generally perpendicular to this mineralisation. No sample bias is known at this time. |
| Sample security | • The measures taken to ensure sample security. |
All geochemical samples were collected, bagged, and sealed by Dreadnought staff and delivered to Exmouth Haulage in Exmouth. Samples were delivered directly to ALS Laboratories Perth by Exmouth Haulage out of Exmouth and Jarrahbar Contracting out of Carnarvon. |
| Audits or reviews | • The results of any audits or reviews of sampling techniques and data. |
The program is continuously reviewed by senior company personnel. |

| Exploration done by other parties |
• Acknowledgment and appraisal of exploration by other parties. |
Historical exploration of a sufficiently high standard was carried out by a few parties which have been outlined and detailed in this ASX announcement including: Regional Resources 1986-1988s: WAMEX Reports A23715, 23713 Peter Cullen 1986: WAMEX Report A36494 Carpentaria Exploration Company 1980: WAMEX Report A9332 Newmont 1991: WAMEX Report A32886 Hallmark Gold 1996: WAMEX Report A49576 Rodney Drage 2011: WAMEX Report A94155 Sandfire Resources 2005-2012: WAMEX Report 94826 |
| Geology | • Deposit type, geological setting and style of mineralisation. |
The Mangaroon Project is located within Mangaroon Zone of the Gascoyne Province. The Mangaroon Project is prospective for orogenic gold, VMS base metals, magmatic Ni-Cu-PGE mineralisation and carbonatite hosted Nb-REEs. |
| Drill hole information | • A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: oeasting and northing of the drill hole collar oelevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar odip and azimuth of the hole odown hole length and interception depth ohole length. • If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |
An overview of the drilling program is given within the text and tables within this document. |
| 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 results reported in this announcement. No metal equivalents are reported. |
| 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’). |
Drilling is undertaken close to perpendicular to the dip and strike of the mineralisation. |
| 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. |
