Massive Sulphides Confirmed in Lower EM Plate at Chianti VMS Target
HIGHLIGHTS
-
Second hole drilled at Chianti VMS Target confirms massive sulphides in the lower EM plate (EM Plate 2).
-
A down hole EM crew has now been mobilised. Drill core will be dispatched for analysis with results expected in the next 4-6 weeks.
-
The rig will be moved to and commence EIS co-funded diamond drilling at the Grants Cu-Au Target.
Dreadnought Resources Limited (“ Dreadnought ” or “ the Company ”) is pleased to announce that the second drill hole (CHDD002) at the Chianti VMS Target has confirmed VMS mineralisation in the lower EM plate (EM Plate 2). As with EM Plate 1, this hole has successfully confirmed the style of mineralisation and that the geophysical methods deployed are effective at identifying VMS mineralisation. Drilling intersected sulphides over two zones as shown in Table 1 below.
| Zone | From(m) | To(m) | Interval(m) | Description of Mineralisation | Description of Mineralisation |
|---|---|---|---|---|---|
| Upper zone | 79.8 | 80.3 | 0.5 | Massive sulphides | 100% suphides comprising cp |
| 80.3 | 82.8 | 2.5 | Semi-massive, bedded massive sulphides | 30-60% sulphides comprising po,cp,sp | |
| Lower zone | 108.0 | 114.8 | 6.8 | Sulphidic sediments | 10-20% sulphides comprising po, cp, sp |
| 114.8 | 116.4 | 1.6 | Sulphidic sediments | 5-20% sulphides comprising of po, cp, sp | |
| 116.4 | 120.0 | 3.6 | Massive sulphides | 80-100% sulphides comprising po, cp, sp | |
| 120.0 | 122.0 | 2.0 | Stringer zone | 10-20% sulphides comprising po,cp |

Dreadnought Managing Director, Dean Tuck, commented “Dreadnought’s second Chianti drill hole has followed on from the success of our first drill hole. This is further confirmation of our exploration model and geophysical techniques which will open up the wider Chianti VMS Target to exploration. There is a large VTEM anomaly over Chianti of which only 20% has been covered by ground EM. Extending these ground EM surveys is now a priority for us. As VMS deposits tend to occur in clusters, we believe there is significant potential for Chianti to contain additional non-outcropping mineralistion.”

Background on the Chianti Cu-Zn-Pb-Ag VMS Target
Chianti was originally defined by Australian Consolidated Minerals (“ ACM ”) in 1972. An airborne electro magnetic (“ VTEM ”) survey flown in 2015 highlighted a conductor beneath the 1972 ACM drilling. A ground fixed loop electro magnetic (“ FLEM ”) survey was recently completed over ~20% of the VTEM conductor and identified two strong EM plates.
==> picture [295 x 296] intentionally omitted <==
==> picture [295 x 287] intentionally omitted <==
The upper EM plate (EM Plate 1) 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 3).
The lower EM plate (EM Plate 2) 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 Figures 2 and 3).
Both EM plates are associated with outcropping and recently rock chip sampled gossans (see Figure 2), 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.

Diamond Drill Hole CHDD002
Diamond drill hole CHDD002 was drilled at a -60 degree angle with an azimuth of 270 degrees to a depth of 135.8m. The hole interesected two sulphide zones:
Upper Zone (79.8m to 82.8m) - an interval of massive and semi massive sulphides within a black, fine grained, sulphide bearing sediment; and
Lower Zone (108.0m to 122.0m) - moved from a fine grained sulphide bearing sediment into massive sulphides and finished in an altered footwall stringer zone.
As expected, the drill hole intersected similar litholgies to CHDD001, with a series of bimodal volcanics, siliclasitic sediments and minor late stage mafic intrusives intersected. Both mineralised zones were closely associated with intensly altered stockwork zones in their footwall positions with stringers and disseminations of various sulphides. Alteration consisted of intense chlorite and silica alteration with localised bleaching. Black fine grained, sulphide bearing sediments were also intersected within the mineralised sequence, these sediments showed evidence of folding and thrusting.
The overall mineralised sequence is interpretted as a structually complex fold hinge. The lithology, alteration and minerlisation styles encountered in both of the completed drill holes is a classical VMS sequence.
The lower zone of massive sulphide mineralisation was intersected near the planned target depth of 110m. Again, this confirms the effectiveness of ground based FLEM for the definition of drill targets at Chianti and VTEM surveys for identifying massive sulphide mineralisation.
These results highlight the potential for the rest of the VTEM anomaly at Chianti to contain additional non-outcropping mineralistion. To date, only about 20% of the VTEM anomaly has been covered with ground based FLEM surveys.
FLEM surveys over the remaining 80% of the VTEM anomaly are now a priority. Orientation soil sampling is also underway to highlight additional base metal anomalism in the area. A down hole EM crew will mobilise now that both holes at Chianti have been drilled. Drill core will be dispatched for analysis with results expected in the next 4-6 weeks.

Diamond Drill Hole CHDD001
Diamond Drill Hole CHDD002 follows on from the first drill hole (CHDD001) at the Chianti VMS Target. CHDD001 confirmed VMS mineralisation in the upper EM plate (EM Plate 1). Drilling intersected sulphides over an interval of 12.7m including a thick stringer zone of sulphide mineralisation followed by massive to semi-massive sulphides.

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 [204 x 279] 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-Zn 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-Zn VMS mineralisation.
The project has known gold and VMS occurrences with drill ready gold targets based on 1990s mineralised gold intercepts which have not been followed up.

| 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.).

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. |

| 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 assays 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 • Intervals reported are downhole intervals. At this stage true widths are unknown, however drilling was designed to test near perpendicular to mineralisation. 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. |

Targets from the VTEM survey are shown in Figure 3 in this report. • Whitewater Resources Pty Ltd completed rock chip sampling of copper gossans in 2013. • Maldron Minerals NL completed rock chip sampling of gossans in 1993. |
| Further work | • The nature and scale of planned further work (e.g. tests for lateral extensions or depth extensions or large-scale step-out drilling). • Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. |
• DHEM will be conducted on drill holes once drilling is completed • Orientation surface geochemistry is being undertaken to determine the applicability of soil sampling • Ground gravity lines will be run over Chianti to determine if gravity techniques can be used to identify massive sulphide targets. • |
