MASSIVE SULPHIDES INTERSECTED IN MULTIPLE HOLES AT ORION Cu-Au-Ag-Co
HIGHLIGHTS
-
8 RC drill holes have been completed to date at Orion, with 6 of these holes intersecting massive sulphides, confirming base metal mineralisation over 120m of strike and remaining open in all directions.
-
Initial drilling is designed to follow up on KMRC017 (12m @ 1.6% Cu, 31.7 g/t Ag and 0.5g/t Au from 45m)
-
RC drilling to commence at Fuso and Grants while downhole EM (“DHEM”) surveys are undertaken at Orion to assist with planning additional drill holes.
-
Drilling updates and assay results are expected throughout October and November 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.
Drilling at Orion has seen 8 holes (846m) of a 23 Hole (2,411m) program completed. This program
==> picture [214 x 400] intentionally omitted <==
follows up on the previous massive sulphide intersection from KMRC017 (12m @ 1.6% Cu, 31.7 g/t Ag and 0.5g/t Au from 45m) testing along strike, at depth and for shallow supergene mineralisation (17 holes) before proceeding to test the remaining EM plates and three magnetic anomalies (6 holes).
Dreadnought’s Managing Director, Dean Tuck, commented: “We are off to an encouraging start with our drilling program at Orion. Strong mineralisation has been observed in six of eight holes with copper, cobalt and zinc sulphide mineralisation present. Down hole EM is currently underway to assist with our targeting at Orion. Orion remains open in all directions. Drilling at Fuso, and Grant’s Find will commence tomorrow and will be followed by the balance of the Orion program on the back of the down hole EM results. Orion, Fuso and Grant’s Find are considered to be part of a large mineralised system and this program is well on its way to providing the framework to determine the scale of the opportunity.”

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. Originally targeted for Ni-Cu-PGE mineralisation within the Ruins Dolerite, a number of anomalies also sit adjacent to significant cross cutting structures which could provide fluid pathways for Proterozoic Cu-Au-Ag mineralisation.
Two RC drill holes for 336m were recently drilled at Orion (see Figure 4), being: EM Plate C (KMRC018); and a magnetic anomaly ~850m north of EM Plate C (KMRC017).
KMRC017 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. The massive sulphide is also strongly magnetic, likely due to pyrrhotite, making other magnetic anomalies attractive drill targets. Given the wellpreserved supergene mineralisation seen across the Tarraji-Yampi project, including at Grant’s Find and Rough Triangle, the shallower up dip projections of the massive sulphide zone are high priority follow up drill targets.
The initial results of DHEM and fixed loop EM (“FLEM”) surveys from Orion, indicate that only the edge of a ~400m x ~300m highly conductive (~4,000-5,000S) plate and coincident magnetic anomaly was intersected.
Eleven RC holes were designed to test the strike extents of the FLEM and DHEM plates associated with
==> picture [307 x 383] intentionally omitted <==
the massive sulphide mineralisation. Six of these holes will also test the potential for high-grade supergene mineralisation. An additional six RC holes will be drilled at EM Plates A and B as well as three additional magnetic anomalies sitting on similar structures as mineralisation intersected in KMRC017.
Drilling should take two to three weeks to complete with rushed assays expected in November 2021. The results of the initial program could lead to additional holes being drilled as part of this program.

Drilling Summary: Massive Sulphide Intersections
KMRC019 and KMRC020 were drilled up and down dip from KMRC017 (12m @ 1.6% Cu, 31.7g/t Ag and 0.5g/t Au from 45m) with both holes intersecting base metal rich massive sulphides.
-
KMRC019 was drilled 40m down dip of KMRC017 and intersected 12m of pyritedominant massive sulphide from 83m, which contained 2 – 10% chalcopyrite. The mineralised zone was hosted in a foliated chlorite-altered mafic with numerous quartz-pyrite-pyrrhotite veins.
-
KMRC020 was drilled 30m up dip of KMRC017 targeting supergene mineralisation but instead intersected 3m of pyrite-dominant semi-massive to massive sulphides from 33m, with up to 5% chalcopyrite and minor sphalerite. The mineralised zone was hosted in a foliated and chlorite-altered mafic that contained disseminated sulphides.

KMRC021 and KMRC022 were drilled 40m northwest along strike from with both holes intersecting base metal rich massive sulphides:
-
KMRC021 intersected a sheared mafic package, with significant chlorite-silica alteration. The alteration halo surrounded a 3m-wide mineralised zone of semimassive sulphides from 45m, which contained 2-20% chalcopyrite.
-
KMRC022 intersected 11m of mineralisation from 78m, which included a highly enriched 5m zone that contained 1525% semi-massive chalcopyrite and significant quartz-carbonate veining. The mafic rocks hosting the mineralised package were strongly altered to a silicachlorite-bearing assemblage.

KMRC023 and KMRC024 were drilled 40m to the southwest along strike of KMRC017 and intersected a possible offsetting fault with minimal chalcopyrite-pyrite bearing quartz veins. The occurrence of an offsetting fault is further supported by magnetic interpretation with mineralisation not considered closed out to the south. DHEM will be undertaken on KMRC024 to test for offset mineralisation.

KMRC025 and KMRC026 were drilled 120m northwest along strike from KMRC017 with both holes intersecting base metal rich massive sulphides:
-
KMRC025 intersected 1m of mineralisation from 41m, containing approximately 10% chalcopyrite within a semi-massive sulphide from 41-42m, hosted in a sheared sulphidic shale and chlorite altered mafic package.
-
KMRC026 intersected two zones of massive sulphides, including 5m of copper-rich mineralisation from 91m, with 1m containing ~5% chalcopyrite. A further 7m of copperzinc mineralisation was intersected from 105m, which included a highly enriched 3m zone with 10-15% chalcopyrite and up to 20% sphalerite.

Drilling to date indicates that there is localised fault offsets and a DHEM survey is underway to assist in targeting the remaining holes. Two more holes are underway at Orion with the balance to be drilled after the DHEM results are received.
All mineralised intercepts from Orion will be rushed through the lab with assays expected in October/November 2021.
Drilling will then progress to test the Fuso magnetic anomalies (4 holes) and then Grant’s Find along strike and at depth (3 holes).

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.
