ASX ANNOUNCEMENT 3 March 2025
Stinger Niobium Exploration Target – Mangaroon 100%
HIGHLIGHTS (All amounts in A$ unless otherwise stated)
• Dreadnought has undertaken an internal study that has highlighted significant economic potential at the Stinger
niobium target (“Stinger”). As a result, a JORC 2012 Exploration Target (“Exploration Target”) has been
estimated for Stinger, part of the Gifford Creek Carbonatite complex that also includes the Yin REE Ironstones
and the C3 REE-Nb Resources (ASX 30 Nov 2023, 28 Aug 2023).
• Stinger has delivered the thickest and highest-grade niobium intercepts in the region with mineralogy results
confirming the commercially viable pyrochlore as the dominate niobium bearing mineral.
• An Exploration Target has been estimated for Stinger over an area of ~1,700m x 500m and to a depth of ~180m
based on drilling results to date:
Table 1: Estimated Stinger Niobium Exploration Target
Tonnage Range (Mt)
15 - 60Mt
Grade Range (% Nb2O5)
0.5% – 1.0%
Contained Nb2O5 Range (t)
150,000 – 300,000t
*Note that the potential quality and grade of the Exploration Target is conceptual in nature, there has been insufficient
exploration to estimate a Resource, and it is uncertain if further exploration will result in the estimation of a Resource. The
Exploration Target has been prepared in accordance with JORC 2012.
• The Exploration Target is based on wide spaced drilling and excludes:
•
Fresh rock depth extensions to Stinger including drill holes ending in mineralisation;
•
Mineralised extensions to Stinger and discoveries within the region; and
•
Other associated critical minerals including titanium, scandium, rare earths and phosphorus.
• An internal study on the smaller, higher grade portion of the Exploration Target, with an open pit down to ~180m
and a standard 1mtpa concentrator supports the significant potential of the niobium and justifies further work
including infill drilling and metallurgical test work. A partner, preferably already in the steel industry (iron ore,
coal, steel), will be sought to advance to this next step.
Dreadnought Resources Ltd (“Dreadnought”) is pleased to announce an Exploration Target
for Stinger, part of the 100% owned Mangaroon Critical Metals Project (“Mangaroon”), in
the Gascoyne region of WA.
Dreadnought’s Managing Director, Dean Tuck, commented: “The Gifford Creek Carbonatite Complex is one of the largest
carbonatite complexes globally and already contains multiple critical minerals including niobium, rare earths, titanium, scandium
and phosphorus. Stinger has produced some of the thickest and highest-grade niobium intercepts to date and our internal
study justifies the next stage of work in conjunction with an industry partner. Importantly, the Exploration Target compares
well to the deposits at global operating
mines.
Dreadnought is now funded to deliver its
self-funded explorer strategy by bringing
the high-grade Star of Mangaroon gold
mine into production. Accordingly,
discussions with potential partners will be
undertaken in the background.
We remain on track to commence our
gold focused exploration drilling in late
March 2025.”

Background
Thick, high grade niobium mineralisation at Stinger was discovered by Dreadnought and has been defined by drilling over
~1,700m x 500m with significant intercepts to date including:
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 @ 0.6% Nb2O5 from 71m, including 26m @ 1.1% Nb2O5 from 99m
CBRC201: 98m @ 0.7% Nb2O5 from 54m, including 41m @ 1.1% Nb2O5 from 85m
CBRC193: 57m @ 0.9% Nb2O5 from 51m, including 10m @ 1.2% Nb2O5 from 72m
CBRC196: 24m @ 0.7% Nb2O5 from 81m, including 8m @ 1.3% Nb2O5 from 81m
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
Mineralisation is predominantly hosted within deeply weathered calcio-magnesio carbonatites of the Gifford Creek
Carbonatite. Mineralogical test work to date has determined that the dominate niobium mineral at Stinger is pyrochlore
with subordinate ilmenorutile. Pyrochlore niobium is commercially viable and accounts for ~95% of global production.
The main mineralisation has been tested with RC drilling and has defined a largely continuous, flat lying sheet of mineralisation
~1,700m in length and up to 500m in width in the deeply weathered sections of the carbonatite with some mineralisation
extending down into the fresh rock. Limited drilling has tested down to the fresh rock at 180m and beyond, which has been
excluded from this Exploration Target.

Estimation Methodology
The preparation of the Exploration Target involved the integration of multiple datasets including drilling, geophysics, geological
logging and geological interpretation.
The footprint of Stinger is defined by broad spaced ~360m x 180m spaced vertical RC holes. Within that footprint, 4 partial
lines of angled fence line drilling have been used to help interpret the geometry of mineralisation at depth. The Exploration
Target has been defined to a maximum vertical depth of ~180m from surface. The mineralisation remains open at depth into
fresh rock and is loosely closed out by broad spaced drilling along strike.
Volume estimates were based on the creation of two wireframes. One using a lower grade 0.1% Nb2O5 cut off and the other
using a higher grade 0.7% Nb2O5 cut off. Mineralised intersections were defined using a minimum down hole width of 6m with
a 0.1% Nb2O5 cut off and a minimum down hole width of 1m with a 0.7% Nb2O5 cut off.
A weighted average of the Nb2O5 grade was calculated on 1,018 assay results using the 0.1% Nb2O5 cut off and on 326 assay
results using the 0.7% Nb2O5 cut off. Using these parameters, the length weighted grade ranged from 0.53% - 1.07% Nb2O5.
These numbers were conservatively rounded down to 0.5% and 1.0% for the Exploration Target grade range.
A total of 266 density measurements were used from diamond drilling in the C3 REE-Nb Resource as coded with lithology
and weathering. A supergene density of 2.0 t/m3 was used for the Exploration Target due to rock type similarities (ASX 28 Aug
2023).

Overview of the Gifford Creek Carbonatite Complex
The Gifford Creek Carbonatite and the Yin Ironstones together form one of the largest alkali-carbonatite complexes in the
world (Figure 5). 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 has delivered
multiple discoveries and Resources, including:
•
Yin REE Ironstones: 29.98Mt @ 1.0% TREO (87% M+I Resource) including 11.63Mt @ 1.9% TREO (94%
M+I Resource) (ASX 30 Nov 2023) over just ~4.6kms of the 43km long Yin Ironstones.
•
C3 REE-Nb Inferred Resource of 10.84Mt @ 1.0% TREO and 0.22% Nb2O5 (ASX 28 Aug 2023).
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
•
CBRC200: 95m @ 0.9% Nb2O5 from 48m, including 20m @ 1.4% Nb2O5 from 102m

Commercialisation Strategy
Dreadnought recently announced a Resource and scoping study for the Star of Mangaroon that includes an initial production
target of ~20koz at 10g/t Au delivering robust financials including a maximum cash drawdown of ~$10M at a AISC of
$1,800/oz and a post capital and tax operating cashflow of ~$40M at a $4,100/oz gold price increasing to ~$50M at forward
gold prices of $4,600/oz (ASX 27 Nov 2024, 28 Jan 2025). Mineralisation at the Star of Mangaroon remains open along strike and
depth with significant potential to add ounces.
Dreadnought is now funded to deliver its self-funded explorer strategy by bringing the high-grade Star of Mangaroon gold
mine into production by delivering the following:
•
•
•
Obtaining the remaining mining approvals for the Star of Mangaroon;
Adding ounces on the existing mining leases (Star of Mangaroon extensions, Popeye, Pritchard, etc.); and
Filling the discovery pipeline with new targets (Bordah, High Range).
The self-funded explorer strategy is Dreadnought’s focus. An internal study on an open pit down to ~180m and a standard
1mtpa concentrator supports the significant potential of the niobium and justifies further work including infill drilling and
metallurgical test work. Accordingly, a partner, preferably already in the steel industry (iron ore, coal, steel), will be sought
to advance to this next step. This potential is further supported by the proximity to existing infrastructure including ports,
roads and gas pipeline (Figure 6).

Fresh niobium mineralisation has been confirmed over 1.2 km strike, open in all directions at Stinger.
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 minerals 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.

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
