SIGNIFICANT MINERALISATION FROM MULTIPLE PROSPECTS AT TARRAJI-YAMPI PROJECT
HIGHLIGHTS
-
RC drilling program (18 RC holes for 3,511m) now completed at the Tarraji-Yampi Project in the West Kimberley region of Western Australia with significant results as follows:
-
13m of massive to semi-massive sulphides intersected at Orion containing ~5-20% chalcopyrite (copper sulphide);
-
5m of chalcopyrite-rich quartz veining (~10-30% chalcopyrite) at Grant’s Find;
- Intense potassic-sulphide alteration and quartz veining at Fuso and Paul’s Find, possibly indicative of a gold bearing system and additional magnetic surveys underway as the magnetic anomaly remains unexplained; and
- 2m of massive sulphide at Chianti containing dominant chalcopyrite, sphalerite and galena.
-
Texas diamond drilling has been delayed due to rig breakdown at 55m. Drilling is expected to recommence early August 2021 with initial results mid-August 2021.
-
RC rig to return September 2021 for follow-up drilling with a copper-gold focus on Orion and Grant’s Find. Assays for the program are due in late August 2021.
Dreadnought Resources Limited (“ Dreadnought ”) is pleased to announce that the RC drilling program at Tarraji-Yampi (18 RC holes for 3,511m) has now been completed. The drilling sequence was Chianti, Fuso, Paul’s Find, Grant’s Find and Orion. The program successfully intersected significant mineralisation and/or alteration across multiple targets.
In total, 18 RC holes for 3,511m have been completed resulting in several significant intercepts including thick chalcopyrite rich massive and semi-massive sulphides in the first hole ever drilled into Orion. RC drilling has demobilised as planned and will recommence in September 2021 with a particular focus on Orion and Grant’s Find.
Dreadnought’s Managing Director, Dean Tuck, commented: “Intersecting massive copper bearing sulphide in the first hole drilled at Orion is a watershed moment for the Tarraji-Yampi project. Furthermore, significant mineralisation and/or alteration was intersected at Grant’s Find, Fuso, Paul’s Find and Chianti with a number of targets still to be tested and new targets emerging. We have rushed assays and expedited downhole and surface geophysical surveys to assist with prioritising follow up drilling. Our obvious priorities are Orion and Grant’s Find with other priorities to be set as further information is forthcoming. We look forward to returning in September 2021 with follow-up RC drilling and to completing the diamond program at Texas in the meantime.”

Drilling at Texas and Orion (E04/2315: 80%)
Texas and Orion are magmatic Ni-Cu-PGE targets hosted within the Ruins Dolerite. In 2015, an airborne VTEM survey was flown resulting in the identification of Texas and Orion as multiple EM anomalies +/- coincident magnetic anomalies hosted within a thick Ruins Dolerite sequence.
Two RC drill holes for 336m were recently drilled at Orion EM Plate C (KMRC018) and into the magnetic anomaly ~850m north of EM Plate C (KMRC017). A ground Fixed Loop EM (“FLEM”) survey was undertaken as planned which highlighted a conductive body associated with the intense magnetic high. While ground truthing the target, a subcropping ironstone with malachite staining was identified and a drill pad was quickly prepared. KMRC017 intersected 13m of massive to semimassive sulphides dominated by pyrite-pyrrhotite and carrying ~5-20% chalcopyrite from 44m

downhole. Downhole EM (“DHEM”) and modelling of the FLEM data is ongoing and will assist with designing follow-up drill holes. Samples have been dispatched to the lab for rush analysis with assay results expected in August 2021.
KMRC018 intersected multiple sulphidic shale horizons dominated by pyrrhotite, pyrite and sphalerite with trace chalcopyrite. A DHEM survey is underway to identify any off-hole conductors.
Based on these encouraging results, further RC drilling at Orion is set to commence in September 2021. This drilling will follow-up on the massive sulphide intercept in KMRC017 and finish testing the A and B EM plates (Figure2).
Diamond drilling at Texas has been delayed due to a breakdown of the diamond rig at 55m depth. Drilling is set to recommence in early August 2021 and to be finished in mid-August 2021.

Drilling at Grant’s Find (E04/2315: 80%)
Grant’s Find is a ~700m long outcropping copper-gold lode that was identified and mined in the 1910s and explored by Western Mining Corporation (“WMC”) in the 1950s. In 2019, Dreadnought drilled two diamond holes into Grant’s Find to determine the tenor of copper and gold mineralisation in fresh rock as WMC had not previously assayed for gold in their drilling.
Despite intersecting encouraging copper mineralisation, including 1.7m @ 3.8% Cu and 0.5 g/t Au, the overall tenor of the gold mineralisation was disappointing.
Upon relogging the core, a 1-2mm gold nugget was identified in GRDD002 on the unassayed half of the core, reigniting interest in Grant’s Find.
==> picture [235 x 212] intentionally omitted <==
Figure 4: Photo of diamond core from GRDD002 showing a 1-2mm gold nugget in a copper bearing quartz vein.
After the recent drill program had commenced, approvals were received for RC drilling at Grant’s Find and three holes were drilled (537m). It is considered that the RC drilling would better represent the nuggety nature of the gold mineralisation. All three holes hit chalcopyrite bearing quartz veining with KMRC016 intersecting 5m of chalcopyrite-rich quartz veining (~10-30% chalcopyrite) from 106m within a broader 9m mineralised intercept.
All samples have been dispatched for rush analysis to determine the presence of any significant mineralisation and to assist with the design and prioritisation of follow-up drilling in September 2021.

Drilling at Fuso and Paul’s Find (E04/2315: 80%)
Fuso and Paul’s Find are Cu-Au targets defined from airborne magnetics and ground gravity surveys undertaken in 2019. Fuso was defined by an intense magnetic high surrounding the northern extent of a strong density anomaly. The ~500m x 400m ovoid gravity feature is cupped on the northern side by the ~1,700m x 700m magnetic anomaly.
5 RC drill holes for 1,125m were drilled into Fuso. The gravity anomaly was determined to be due to a medium to coarse grained mafic intrusion, following which attention turned to focus on the magnetic anomalies. Four holes were drilled to test the magnetic anomaly and intersected multiple zones of chlorite-sulphide alteration with locally significant quartz-sulphide-carbonate veining. This alteration and mineralisation is suggestive of an orogenic gold system; however, the source of the magnetic anomaly remains unresolved.
One metre samples have been dispatched for rush analysis and additional magnetic surveys are ongoing to assist with defining the magnetic anomalies for follow-up testing.
Paul’s Find is defined by an intense, reversely/remanently magnetised anomaly with a coincident density anomaly. A single RC hole for 249m was drilled into Paul’s Find intersecting a sheared potassic and sulphide altered hornblende-rich lithology with isolated quartz-sulphide veining. The hornblendite is interpreted to be part of a fractionated mafic intrusion with potential to host Ni-CuPGE mineralisation at depth. In addition, the shearing and alteration have the potential to host orogenic gold mineralisation.
All samples have been dispatched for rush analysis to determine the presence of any significant mineralisation and to assist with the design and prioritisation of follow-up drilling in September 2021.

Drilling at Chianti-Rufina Cu-Zn-Ag (E04/2508: 100%)
Chianti was originally defined and drilled by Australian Consolidated Minerals in 1972. An airborne VTEM survey flown in 2015 highlighted a conductor beneath the 1972 drilling. Since acquiring the project, Dreadnought has carried out a FLEM survey covering a portion of the VTEM conductor which contained outcropping gossans and historical drilling. The FLEM survey identified two strong EM plates which were then drilled in late 2019 and successfully intersected highly magnetic massive sulphide mineralisation (refer ASX 2 December 2019).
7 RC holes were drilled for 1,264m into seven FLEM plates with associated outcropping gossans, magnetic anomalies and/or soil anomalies within the interpreted prospective VMS horizon (Figure 7).
KMRC001, drilled into Chianti intersected 2m of massive sulphide dominated by pyrrhotite and pyrite with significant chalcopyrite, sphalerite and minor galena.
Barolo, Amarone and Rufina intersected sulphidic mud horizons with minor base metal sulphides indicative of a prospective mineralised exhalative horizon. DHEM surveys are currently underway across all 7 drill holes with results expected in August 2021.

Update on Target Definition at Tarraji-Yampi (E04/2315: 80%)
Detailed mapping at Rough Triangle has identified outcropping masses of cuprite (a high-grade copper oxide) which is encouraging of a preserved oxide and supergene sulphide zone at Rough Triangle. Mapping has confirmed the main lode is 1m to 5m thick with outcropping mineralisation concentrated in the northern ~600m of the ~1.2km long lode, where the lode exploits a zone of structural complexity in the host sediments. Additionally, multiple veins including parallel veins have been identified along strike increasing the potential for additional mineralisation.
==> picture [315 x 201] intentionally omitted <==
Systematic surface sampling has been completed over Rough Triangle and six additional outcropping copper bearing lodes at Tarraji with assays expected in August/September 2021.

Airborne magnetic surveys at Yampi and Wombarella (E04/2508, E04/2572, E04/2557, E04/2608, E04/2560: 100%)
A detailed airborne magnetic survey has commenced over the Yampi and Wombarella tenements. The survey consists of ~15,000-line kilometres of 100m and 50m spaced flight lines. The results of this
survey will assist with lithostructural interpretations of the Yampi and Wombarella tenements as well as to generate targets for follow-up work. Results are expected in September 2021.

Background on Tarraji-Yampi
Tarraji-Yampi is located entirely within the Yampi Sound Training Area (“YSTA”), a commonwealth owned defence reserve in the West Kimberley, ~80kms from the port of Derby. The YSTA is the second largest defence reserve in Australia after Woomera in South Australia and has been off limits to mineral exploration from 1978 to 2013.
Copper was discovered and mined in the early 1900s with the only significant exploration undertaken by WMC in 1958 and Australian Consolidated Minerals in 1972 with both parties exploring for copper. Since opening for exploration in 2013, Dreadnought has secured the largest ground holding within the YSTA and developed strong working relationships with both the Department of Defence and the Dambimangari People. Dreadnought has completed successful drilling programs at the Chianti-Rufina VMS and Grant’s Find Cu-Au targets. In addition, geophysical and geochemical surveys have resulted in the definition of >12 drill targets.

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 1900s which have seen no modern exploration.
Three styles of mineralisation occur at Tarraji-Yampi including: volcanogenic massive sulphide (“ VMS ”); Proterozoic Cu-Au; and magmatic sulphide Ni-CuPGE. Numerous high priority nickel, copper and gold drill targets have been identified from recent VTEM surveys, historical drilling and surface sampling of outcropping mineralisation.
==> picture [261 x 358] intentionally omitted <==
Illaara Gold, VMS & 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 and base metals VMS mineralisation.
Dreadnought has consolidated the Illaara Greenstone Belt mainly through an acquisition from Newmont. Newmont defined several camp-scale targets which were undrilled due to a change in corporate focus. Prior to Newmont, the Illaara Greenstone Belt was predominantly held by iron ore explorers and has seen minimal gold and base metal exploration since the 1990s.
Mangaroon Ni-Cu-PGE, REE & Au Project
Mangaroon is a first mover opportunity covering ~4,500sq kms of tenure located 250kms south-east of Exmouth in the Gascoyne Region of Western Australia. During most of the regions early history, it did not receive government support for prospecting and or exploration resulting in a vastly underexplored region in Western Australia.
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. Mangaroon is still in the early stages with limited modern exploration.
