HIGH PRIORITY COPPER GOLD TARGETS AT FUSO AND PAUL’S FIND
HIGHLIGHTS
-
3D Inversion of magnetic and gravity data has refined the Fuso Cu-Au target and confirmed a ~500m x 400m high density gravity anomaly nestled within a ~1,700m x 700m south-southeast plunging magnetic anomaly
-
Paul’s Find is confirmed as a coincident intense ~300m x 200m remanently magnetic and density anomaly located near surface
-
RC drilling will commence at Tarraji-Yampi during the December 2020 quarter. The sequence and timing of the program will be advised in early September 2020. This will allow for mobilisation costs and drill productivity to be optimised.
Dreadnought Resources Limited (“ Dreadnought ”) is pleased to announce the results of 3D inversion of the detailed magnetic and gravity surveys at the Fuso and Paul’s Find Cu-Au targets.
The 3D inversion at the Fuso Cu-Au target has refined and confirmed an intense south-east dipping magnetic anomaly with a central gravity anomaly associated with demagnetisation (see Figure 1). This geophysical signature is typical of Proterozoic Cu-Au deposits such as those seen in Tennant Creek and Mt Isa. With ~1.7km of strike on the magnetic anomaly and ~500m of strike on the gravity anomaly, the target has significant scale.
Dreadnought Managing Director, Dean Tuck, commented: “Dreadnought is excited about the results of these surveys which highlight the scale and attractiveness of our targets in an area which seen no exploration since 1978. Fuso and Paul’s Find are large and intense coincident magnetic-gravity targets completely undercover with an abundance of Cu-Au-Bi-Sb smoke.”

3D Inversion of Fuso and Paul’s Find Cu-Au
In 2019, Dreadnought undertook a detailed airborne magnetics survey which highlighted several magnetic anomalies. Most of the anomalies are located undercover with no outcrop. To prioritize these anomalies and to define a target for drill testing, a 200m x 50m ground gravity survey was also undertaken. These surveys resulted in defining two coincident magnetic and gravity anomalies at Fuso and Paul’s Find.
As both targets are undercover, the magnetics and gravity data were then used to create a 3D Inversion model to better constrain the geometry of the anomalies and to define drill targets.
At Fuso, there is an intense magnetic high surrounding the northern extent of a strong density anomaly. Inversion modelling suggests a south to south-easterly dip with the top of the anomaly at 50-100m depth. The ~500m x 400m ovoid gravity feature is cupped on the northern side of the ~1,700m x 700m magnetic anomaly. The magnetic anomaly is interpreted to be related to intense iron rich alteration, either as magnetite or pyrrhotite and the gravity signature conceptually represents the mineralised lode.
At Paul’s Find, there is an intense, isolated, reversely/remanently magnetised anomaly with a coincident density anomaly. Inversion modelling suggests that the isolated feature is located near surface with dimension of ~300m x 200m. The magnetic low is interpreted to be remnant magnetisation associated with a mineralised lode.
Both Fuso and Paul’s Find are located in close proximity to a high-K felsic intrusion and a splay in crustal scale structures, both of which have known outcropping Cu-Au mineralisation.
RC drilling at Fuso will be designed to test the contacts of the magnetic and gravity anomalies as well as the centre of the gravity anomaly. At Paul’s Find, RC drilling will be designed to test the coincident magnetic and gravity anomaly. See Figure 4.
==> picture [328 x 259] intentionally omitted <==
Both targets are high priority. All drilling approvals are in place for Fuso. At Paul’s Find, a heritage survey is planned for September 2020, otherwise all other approvals are in place.

Background on the Fuso and Paul’s Find Cu-Au Targets
Fuso and Paul’s Find are the first priority targets to result from the recent airborne magnetics and ground gravity surveys.
This work was motivated by the comparisons of the lithostructural and geochemical signature of Tarraji-Yampi to other Proterozoic Cu-Au terranes such as Tennant Creek Inlier (ex. Gecko, Peko) and Mt Isa (ex. Brumby, Ernest Henry).
In these terranes, Proterozoic Cu-Au deposits occur as coincident magnetic-gravity anomalies regionally associated with Proterozoic high-K intrusions. Deposits are also likely to form topographic lows with no outcrop. With this model, outcropping quartz copper lodes, as seen at Grants and Wilsons (see Figures 3 and 5), could represent distal hydrothermal mineralisation and work as a vector towards mineralisation undercover. Both Fuso and Paul’s Find are located in close proximity to the Mondoooma Granite which is a high-K felsic intrusion similar in age to intrusions at Tennant Creek.

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. The area was only recently opened under the Commonwealth Government’s co-existence regime that balances Defence’s needs with the requirements of others including Aboriginal groups, the resources industry, pastoralists and State Governments.
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-
==> picture [236 x 322] intentionally omitted <==
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. Illaara contains several drill ready gold targets. In addition, the Eastern and Western VMS Horizons are expected to produce exciting drill targets with the application of modern exploration technology.
Rocky Dam Gold & VMS Project
Rocky Dam is located 45kms east of Kalgoorlie in the Eastern Goldfields Superterrane of Western Australia. Rocky Dam is prospective for typical Archean mesothermal lode gold deposits and Cu-Zn VMS mineralisation. Rocky Dam has known gold and VMS occurrences with drill ready gold targets including the recently defined CRA-North Gold Prospect.

Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
| Criteria | JORC Code explanation | Commentary | |
|---|---|---|---|
| Sampling techniques |
• 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 has inherent sampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information. |
The 3D inversion modelling were processed by Southern Geoscience Consultants Pty. Ltd. (SGC) (Perth) using the Geosoft VOXi inversion code. Magnetic inversions were conducted using standard Susceptibility and Magnetic Vector Inversion (MVI) algorithms due to expected remanent magnetism associated with the Paul’s Find magnetic feature. The inversion parameters are below: Technique Area Resolution Dimension Suscep/MVI 3.8x2.4km 25m 150x94x30 Density 3.8x2.4km 100m 38x24x16 Magnetic data used was from a 2019 airborne survey flown by MagSpec which was conducted on 50m spaced E-W flight lines at a nominal altitude of 33m. Gravity data used was from a 2019 ground gravity survey acquired by Atlas Geophysics at 200m spaced traverses and 50m spaced station spacing. Further details regarding the gravity survey is reported in the ASX Announcement dated 23 December 2019. |
