TARRAJI-YAMPI PROJECT
SUPERGENE CONFIRMED AND MASSIVE SULPHIDES EXTENDED AT ORION Cu-Au-Ag-Co
HIGHLIGHTS
-
Mineralisation at Orion is now confirmed from a depth of ~1m to ~150m down dip and along strike for ~240m and remains open at depth and along strike. This includes multiple supergene (chalcocite) and oxide (gossanous) intercepts in the top 20m from surface. Of 29 holes drilled at Orion, 19 intersected massive to semi-massive sulphides or supergene / oxide mineralisation.
-
Magnetic targets at Orion and Fuso containing multiple zones of copper and cobalt mineralisation within chlorite and silica altered sediments and mafics also confirm additional mineralisation potential.
-
Due to the wet season, drilling at Tarraji-Yampi has finished with a total of 32 RC drill holes drilled for 3,921m. Assay results are expected through November/December 2021.
Dreadnought Resources Limited (“ Dreadnought ”) is pleased to provide an update on the RC drilling program at the Tarraji-Yampi Project in the West Kimberley region of Western Australia.
A program of 32 RC holes (3,921m) has been completed at the Orion and Fuso prospects. At Orion, recent drilling focussed on a geophysical anomaly that extends ~400m in strike and to a depth of at least 500m. The anomaly contains a recent massive sulphide intersection ( KMRC017 12m @ 1.6% Cu, 31.7 g/t Ag & 0.5g/t Au from 45m ). This work included testing along strike and at depth from KMRC017 as well as for nearby, shallow supergene mineralisation. Furthermore, 6 magnetic anomalies around Orion and Fuso were tested.
Dreadnought’s Managing Director, Dean Tuck, commented: “Of the 29 holes drilled at Orion this season, 19 intersected massive to semi-massive sulphides or supergene / oxide mineralisation which
==> picture [229 x 272] intentionally omitted <==
confirmed our targeting techniques as well as the potential scale of the system. Mineralisation is now confirmed over ~240m of strike and to a depth of 150m and remains open. Orion also has oxide and supergene mineralisation from 1m depth. Orion, Fuso and surrounds are proving more and more to be part of a large mineralised system with similar geochemical signatures to Proterozoic Cu-Au / sedimentary copper systems with the rocks showing similar age, mineralisation and alteration as the Mt Isa Region.”

Program at Orion Cu-Au-Ag-Co (E04/2315: 80%)
Orion consists of multiple magnetic and EM anomalies within a thick 4km long Ruins Dolerite and sediment package. A number of anomalies sit adjacent to significant cross cutting structures which could provide fluid pathways for Proterozoic Cu-Au-Ag-Co mineralisation.
During the 2021 field season 29 RC holes (3,240m) were drilled at Orion over 2 programs and included KMRC017 which intersected 12m @ 1.6% Cu, 31.7g/t Ag and 0.5g/t Au from 45m from an interval of massive to semi-massive sulphides within the Ruins Dolerite. Subsequent to drilling KMRC017, downhole and fixed loop EM surveys (Figure 3) modelled the anomaly at Orion to extend over ~400m of strike and to ~500m in depth (being the limit of the EM surveys’ effectiveness).
During the second program 27 RC holes (2,904m) were drilled at Orion to test the anomaly’s strike length and depth extent, as well as to test for nearby supergene mineralisation and 3 RC holes were drilled to test 3 additional magnetic anomalies. Of the 27 holes, 14 intersected massive to semimassive sulphides and a further 4 holes intersected supergene mineralisation.
Mineralisation has now been confirmed over ~240m in strike from within ~1m of surface to ~150m down dip with mineralisation remaining open along strike and at depth.
Massive sulphide mineralisation consists of pyrrhotite-pyrite-chalcopyrite-cobaltite and zones into more pyrrhotite-pyrite-chalcopyrite-sphalerite and galena rich compositions to the north and occasionally along the margins of the massive sulphide intervals. This zonation is likely due to a temperature gradient and/or multiple overprinted pulses within the mineral system.
The massive sulphide mineralisation occurs in a sequence of graphitic shales and siltstones and fine to medium-grained foliated dolerite and mafic schists. The mineralised lodes are approximately conformable with the stratigraphy and dip from 55-70 degrees to the east, ranges in thickness from 1- 16m and generally increases in thickness and tenor down dip. The results align with stronger modelled EM and magnetic responses at depth. Several NW-trending faults offset the lode and may offset, but not necessarily close off, the mineralisation to the south.

Oxide and supergene mineralisation is developed in the weathered portions of the lode down to ~20m depth and is marked by iron rich gossans and secondary copper carbonates in the oxide portions and chalcocite in the supergene.
==> picture [260 x 272] intentionally omitted <==
A palaeochannel ranging from 1-5m thick covers the shallowest portions of the mineralisation making it blind at surface.
In addition, three holes (357m) were drilled into magnetic anomalies with multiple zones of copper and cobalt minerals intersected within sheared, sulphide altered mafic rocks. These results indicate that additional lodes of massive sulphide mineralisation may exist within the broader Orion area.

Program at Fuso Cu-Au-Ag-Co (E04/2315: 80%)
Fuso is a Cu-Au-Ag-Co prospect 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 a ~1,700m x 700m magnetic anomaly.
Earlier this year, 5 RC holes for 1,125m were drilled into Fuso. The gravity anomaly was tested and determined to be due to a medium to coarse grained mafic intrusion. However, multiple zones of chlorite-sulphide alteration with locally significant quartz-sulphide veining were intersected and the source of the magnetic anomaly remained unexplained. Encouragingly, 1 hole (KMRC012) intersected 1m @ 2.1% Cu, 0.1 g/t Au, 3.9 g/t Ag and 0.2% Co from 90m . Given the chemical similarity to Orion and, because no magnetic lithologies were intersected downhole, this intercept was interpreted as a near miss.
Recently, 4 additional holes (834m) were drilled at Fuso to test the two main magnetic anomalies and a third smaller anomaly to the northeast. KMRC028 and KMRC029 tested the main magnetic anomalies with KMRC029 intersecting thin mineralisation similar to KMRC012. Down hole magnetic surveys were undertaken confirming strong remanence in the magnetic signature. This data is being reviewed with additional drilling to be undertaken in 2022.
KMRC030 and KMRC031 tested the NE magnetic anomaly with KMRC031 intersecting Cu-Co mineralisation within chlorite and silica altered black shales.
Mineralised intercepts have been prioritised with results expected in November/December 2021.

Background on Tarraji-Yampi
Tarraji-Yampi is located entirely within the Yampi Sound Training Area (“ YSTA ”), a Commonwealth 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 was off limits to mineral exploration from 1978 to 2013.
In 1906, Mr J.H. Grant, a mining engineer from Ballarat working with local prospector Mr. G.J. Poulton, reported the discovery of copper lodes in the Mt Nellie district and took out several mining leases for the Oobagooma Copper Syndicate. Small scale shafts were developed at Grant’s Find, Wilson’s Reward, Ironclad and Monarch.
Since the Oobagooma Copper Syndicate, the only significant exploration undertaken was by WMC Resources 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.

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 1900’s which have seen no modern exploration.
Results to date indicate that there may be a related, large scale, Proterozoic Cu-AuAg-Bi-Sb-Co system at Tarraji-Yampi, similar to Cloncurry / Mt Isa in Queensland and Tennant Creek in the Northern Territory.
Mangaroon Ni-Cu-PGE, REE & Au Project
==> picture [256 x 351] intentionally omitted <==
Mangaroon is a first mover opportunity covering ~4,500sq kms of tenure located 250kms south-east of Exmouth in the Gascoyne Region of WA. During the region’s early history, there was limited government support for exploration resulting in the region being vastly underexplored.
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.
Illaara Gold, Base Metals, Critical Minerals & 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, VMS base metals and critical metals including Lithium-Caesium-Tantalum.
Dreadnought has consolidated the Illaara Greenstone Belt mainly through an acquisition from Newmont. Prior to Newmont, the Illaara Greenstone Belt was predominantly held by iron ore explorers and remains highly prospective for iron ore.
