FURTHER HIGH GRADE ROCK CHIP RESULTS FROM THE CHIANTI VMS TARGET AT YAMPI
HIGHLIGHTS
-
High‐grade rock chip results confirm extension of mineralised gossan at the Chianti Target
-
Mineralised rock chips aligned with the entire strike of FLEM plates
-
Drilling approvals well advanced with final approval expected in the September 2019 quarter
Dreadnought Resources Ltd (“Dreadnought” or “the Company”) is pleased to announce the results of surface rock chip sampling at the Chianti Target at the Tarraji‐Yampi Ni‐Cu‐Au Project (“Tarraji” or “the Project”) in the West Kimberley Region of Western Australia. These additional samples were collected during the recent heritage and environmental surveys and covered the strike extent of gossans which were historically mapped in the 1970s. These new results confirm the outcropping gossan is mineralised in Cu‐Zn‐Pb‐Sn‐Ag‐Au along the entire strike of defined FLEM plates (see Figure 1 and Table 1).

Background on the Chianti Cu‐Zn‐Pb‐Ag VMS Target
Chianti was originally defined by Australian Consolidated Minerals (“ACM”) in 1972. An airborne EM survey flown in 2015 highlighted an EM conductor beneath the 1972 ACM drilling. A FLEM survey was recently completed over part of the airborne EM conductor and identified two strong EM plates.
The Upper EM plate is roughly 100m x 40m with a moderate to high conductivity of 900 siemens. The top of this EM plate is ~25m below the surface and lines up with the historical ACM drill intercepts (see Figure 2):
-
PD1: 4.57m @ 1.13% Cu, 0.69% Pb, 2.05% Zn, 21.7 g/t Ag from 10.7m; and
-
DDH3: 6.55m @ 1.23% Cu, 0.93% Pb, 2.85% Zn, 32.2 g/t Ag from 36m.
The Lower EM plate is roughly 160m x 80m with a high conductivity of 2,050 siemens and appears to be fault offset in section view extending to a depth of ~150m (See Figure 2).
Dreadnought’s recent rock chip sampling was designed to confirm mineralisation, characterise the different lithologies and to provide a geochemical signature to the alteration to help fingerprint the mineralisation system responsible for the outcropping gossans. Rock chips samples were collected from in‐situ outcrops where available, however ACM disturbed the Chianti area with numerous costeans. Because the costeans have collapsed and become overgrown, multiple samples of different lithologies and styles of mineralisation were collected from piles at each end of the costeans to assist with understanding the immediate area.
==> picture [299 x 290] intentionally omitted <==
Both EM plates are associated with outcropping and mapped gossans (see Figure 1), covering almost 200m of strike. When combined with the rock chips and previous drill intercepts, the EM plates create compelling high priority targets for drill testing.

INVESTMENT HIGHLIGHTS
Tarraji‐Yampi Ni‐Cu‐Au Project
Dreadnought controls a significant land holding in the highly prospective West Kimberley located only 85 kms from Derby, Western Australia. The project area has been locked up as a Defence reserve since 1978 and was only recently opened under the Commonwealth Government’s coexistence regime that balances Defence needs with the requirements of others including Aboriginal groups, the resources industry, pastoralists and State Governments.
The Tarraji‐Yampi Ni‐Cu‐Au Project presents a rare first mover opportunity in Western Australia with known outcropping mineralisation and historic workings from the early 1900s which have seen no modern exploration.
==> picture [182 x 250] intentionally omitted <==
Three styles of mineralisation occur at Tarraji 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 Au‐Cu‐Zn Project:
The Illaara Au‐Cu‐Pb‐Zn Project is located 160km northwest of Kalgoorlie‐Boulder in the world class Yilgarn Craton and covers 75 strike kilometres of the Illaara Greenstone Belt. The Project is prospective for typical Archean mesothermal lode gold deposits and Cu‐Pb‐Zn‐Ag VMS mineralisation.
The project was acquired from Newmont Goldcorp who
defined several camp‐scale targets which were undrilled due to a change in corporate focus. Prior to Newmont Goldcorp, the Illaara greenstone belt was held predominantly by iron ore explorers and has seen minimal gold and base metal exploration since the 1990s. The project contains several drill ready gold targets and known VMS horizons which could produce exciting drill targets with the efficient and effective application of modern exploration technology.
Rocky Dam Au‐Cu‐Zn Project:
The Rocky Dam Au Project is located 45kms east of Kalgoorlie‐Boulder in the world class Eastern Goldfields Superterrane of Western Australia. The Project is prospective for typical Archean mesothermal lode gold deposits and Cu‐Pb‐Zn‐Ag VMS mineralisation.
The project has known gold and VMS occurrences with drill ready gold targets based from 1990s mineralised gold intercepts which have not been followed up.

JORC Code, 2012 Edition – Table 1 report template Section 1 Sampling Techniques and Data
JORC TABLE 1
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. |
Current Exploration Fixed Loop EM (FLEM) surveyed at 25m and 50m station spacing with 50m and 100m spaced lines. FLEM stations were planned perpendicular to geological strike of target horizons. Rock Chips were collected by Dreadnought staff and submitted for analysis. Rock chips are random, subject to bias and often unrepresentative for the typical widths required for economic consideration. They are by nature difficult to duplicate with any acceptable form of precision or accuracy. Rock chips have been collected by Dreadnought to assist in characterising different lithologies, alterations and expressions of mineralisation. In many instances, several rock chips were collected from a single location to assist with characterising and understanding the different lithologies, alterations and expressions of mineralisation present at the locality. Rock chips were submitted to ALS Laboratories in Perth for determination of Au, Pt and Pd by PGM- ICP24 and multiple (48) elements by ME-MS61 Historical Exploration WMC completed diamond drilling at Yampi in the 1950s. The drilling intersected copper mineralisation, but sampling techniques are not known. ACM completed percussion and diamond drilling at Chianti in the 1970s. The drilling intersected base metal mineralisation, but sampling techniques are not known. Versatile time domain electromagnetic (VTEM) and aeromagnetic data acquired for Rio Tinto Exploration in October 2015 were flown by UTS Geophysics using an A-star 350 B3 helicopter with a VTEM max receiver and transmitter and Geometrics caesium vapour magnetic sensor. |
| Drilling techniques |
Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc.). |
Current Exploration No drilling undertaken. Historical Exploration Diamond drilling at Grants and Wilsons, percussion and diamond drilling at Chianti. |

Being freehold Commonwealth Land, there is no Native Title over these tenements. E04/2608 is partly located within the YSTA and partly on Vacant Crown Land which has Native Title claim by the Warra Combined (NNTT Number 2901) |
| Exploration done by other parties |
Acknowledgment and appraisal of exploration by other parties. |
Regional mapping, basic stream sediment, soil sampling and limited diamond drilling was completed by WMC in the 1950s. Shallow percussion and diamond drilling was undertaken by ACM at Chianti in the 1970s. The YSTA was off limits to exploration from 1978 until 2013. |
| Geology | Deposit type, geological setting and style of mineralisation. |
The Tarraji-Yampi Project is located within the Hooper Complex which is a Proterozoic Mobile Belt in the West Kimberley. The Hooper Complex has known occurrences of Cu-Zn-Pb-Ag VMS mineralisation within the Marboo Formation, magmatic Ni-Cu-PGE mineralisation in the Ruins Dolerite and later stage Proterozoic Cu-Au mineralisation associated with significant structures and late stage intrusions. |

| If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |
||
| Data aggregation methods |
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually Material and should be stated. Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. The assumptions used for any reporting of metal equivalent values should be clearly stated. |
Current Exploration No drilling reported. Historical Exploration Reported mineralised intercepts are from historical reports and sections. Historical intercepts appear to be weighted averages, but no information is known regarding techniques or cut offs used. |
| Relationship between mineralisation widths and intercept lengths |
These relationships are particularly important in the reporting of Exploration Results. If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (e.g. ‘down hole length, true width not known’). |
Current Exploration No drilling was undertaken. Historical Exploration Chianti was drilled at 60 degrees to the west into a N-S trending and east dipping mineralised lode. This drilling is believed to be largely perpendicular, but reported thicknesses are down hole thicknesses and cannot be converted to true thickness based on current knowledge. Grants and Wilsons were drilled at 60 degrees to the west into a N-S trending and near vertical dipping mineralised lode. This drilling is believed to be largely perpendicular and with some bias, but reported thicknesses are down hole thicknesses and cannot be converted to true thickness based on current knowledge. |
| Diagrams | Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. |
Refer to figures within this report. |
| Balanced reporting | Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. |
