HIGH-GRADE Cu-Ag-Sb-Bi MINERALISATION AT ROUGH TRIANGLE – TARRAJI-YAMPI
HIGHLIGHTS
-
From a total of 16 reconnaissance rock chip samples, 13 have returned highly mineralised polymetallic results from Rough Triangle. Significant results include:
-
RT07: 20.4% Cu, 4.6% Sb, 0.9% Bi, 101g/t Ag
-
RT08: 8.1% Cu, 2.2% Sb, 0.3% Bi, 44.5g/t Ag
-
RT09: 18.9% Cu, 14.1% Sb, 1.6% Bi, 196g/t Ag • RT12: 18.5% Cu, 10.8% Sb, 1.9% Bi, 291g/t Ag
-
Rough Triangle is an outcropping lode over 1.2kms long, 1m to 5m in width with multiple parallel lodes.
-
Systematic sampling and mapping are underway with further results expected in August 2021.
Dreadnought Resources Limited (“ Dreadnought ”) is pleased to announce results of reconnaissance sampling at Rough Triangle, part of the Tarraji-Yampi Project in the West Kimberley region of Western Australia.
Rough Triangle was identified and mapped by Western Mining Corporation ( “WMC” ) in 1958. Even though it was declared a “significant lode” after mapping by WMC, Rough Triangle was not sampled. No exploration has been undertaken at Rough Triangle since 1958.
Rough Triangle was sampled by Dreadnought as part of a project wide reconnaissance program assessing historically mapped mineralisation and more recently generated anomalies. The results of this sampling have confirmed high tenor polymetallic mineralisation, including critical minerals Antinomy (Sb) and Bismuth (Bi), in addition to Copper (Cu) and Silver (Ag) over ~600m of strike length.

Systematic sampling and mapping of the outcropping lodes is currently underway with an aim to define drill targets. Further assay results are expected in August 2021.
Dreadnought’s Managing Director, Dean Tuck, commented: “We have no shortage of outcropping mineralisation at TarrajiYampi. There is certainly nothing more exciting than walking along walls of outcrop with copper staining. The confirmation of high tenor antimony, bismuth, copper and silver is highly encouraging for a substantial system at Rough Triangle. We will continue to assess additional targets while undertaking our drilling programs at Texas, Fuso, Paul’s Find, Orion and Chianti-Rufina.”

Rough Triangle Cu-Ag-Sb-Bi (E04/2315: 80%)
From 1957-1959 WMC explored the “Tarraji Copper Project” for sedimentary copper deposits. This was the only exploration conducted before the area was declared a Defence Reserve in 1978.
lode hosted within intensely bleached and silicified sediments. The lode was mapped continuously over 1,280m and ranged thickness from 1m to 5m with copper mineralisation evident throughout the lode. In addition to the main lode, parallel lodes were observed running >300m in length before going under cover.
The Rough Triangle lode was never sampled by WMC.
Recently, 16 reconnaissance rock chips were collected over ~600m along the outcropping lode to assess the tenor of mineralisation at Rough Triangle. Of these samples, 13 returned high grades of Cu-Ag-Sb-Bi with accessory Au (Table 1.).
Results from additional sampling and mapping are expected in August 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 since undertaken by Western Mining Corporation 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 Grants 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 (“ IOCG ”); and magmatic sulphide Ni-Cu-PGE. Numerous high priority nickel, copper and gold drill targets have been identified from recent VTEM surveys, historical drilling and surface sampling of outcropping mineralisation.

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.
