ASSAYS AND EM SURVEYS CONFIRM MASSIVE SULPHIDE SYSTEM AT CHIANTI-RUFINA
HIGHLIGHTS
-
Assays confirm massive sulphide mineralisation:
-
Upper Plate: CHDD001: 61.4m-61.9m: 6.0% Zn, 0.7% Pb, 0.2% Cu, 14.1 g/t Ag Lower Plate: CHDD002: 79.8m-80.3m: 1.9% Cu, 2.2% Zn, 1.0% Pb, 37.6 g/t Ag CHDD002: 116.4m-120m: 1.0% Cu, 4.9 g/t Ag
-
Down Hole EM (“DHEM”) indicates that only the fringe of the upper plate was intersected and that the upper plate is part of a stacked lode above the lower plate
-
The lower plate remains open and is providing a much stronger EM response (10k siemens DHEM vs 2k siemens Fixed Loop EM (“FLEM”)) indicating higher pyrrhotite-chalcopyrite Cu mineralisation
-
There is potential for further stacked lodes beneath the lower plate
-
Six larger FLEM plates have been generated nearby to Chianti associated with outcropping gossans, magnetic anomalies and Versatile Time EM (“VTEM”) anomalies – indicating potential for a number of VMS deposits
Dreadnought Resources Limited (“ Dreadnought ” or “ the Company ”) is pleased to announce that assay results have confirmed significant VMS mineralisation at Chianti. In addition, DHEM results indicate Chianti is comprised of stacked lodes. The lower plate is showing a much stronger EM response and has the potential for further stacked loads below it. The DHEM survey also shows that the upper plate is located further to the south than expected.
At Rufina, FLEM surveys generated an additional six plates, all larger than Chianti. The Rufina plates are associated with gossans and/or strong magnetic anomalies. This further highlights the potential of Chianti-Rufina to host a number of VMS deposits.
Dreadnought Managing Director, Dean Tuck, commented “Our VMS work in 2019 has been a success. At Chianti, we have already identified significant VMS mineralisation in multiple stacked lodes. Assay results confirm the tenor of historical ACM intercepts at Chianti and are aligned with the previously reported massive sulphide intervals . Our targeting approach has also been validated leading to six additional large drill targets being identified. It is clear that the area could host host a number of VMS deposits and we look forward to follow up drilling at Chianti and the nearby targets in 2020.”

Background on the Chianti VMS Target
Chianti was originally defined by Australian Consolidated Minerals (“ ACM ”) in 1972. An airborne VTEM survey flown in 2015 highlighted a conductor beneath the 1972 ACM drilling.
A ground FLEM survey was completed over the outcropping gossans and historical drilling covering ~20% of the VTEM conductor and identified two strong EM plates. The upper plate (EM Plate 1) was modelled at ~100m x 40m with a moderate to high conductivity of 900 siemens. The top of the upper plate was modelled at ~25m below surface and lined up with the historical ACM drilling (see Figure 3).
==> picture [261 x 261] intentionally omitted <==
==> picture [261 x 253] intentionally omitted <==
The lower EM plate (EM Plate 2) was modelled at ~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 3 and 4).
The plates were diamond drilled (CHDD001 and CHDD002 respectively) as designed. Both holes intersected massive sulphide mineralisation within a sequence of bimodal volcanics, potential minor mafic intrusives and minor siliciclastic lithologies and showed classic VMS textures and alteration.
A DHEM survey was carried out over each hole.
In addition, three FLEM surveys were conducted over several anomalies within the interpreted VMS horizon as identifed by outcropping gossans, magnetic anomalies and VTEM anomalies.

Diamond drill hole CHDD002 was drilled into the lower plate at a -60 degree angle with an azimuth of 270 degrees to a depth of 135.8m. The hole interesected two sulphide zones. An Upper Zone (79.8m to 82.8m) consisting of massive and semi massive sulphides within a black, fine grained, sulphide
==> picture [267 x 448] intentionally omitted <==
bearing sediment; and a Lower Zone (108.0m to 122.0m) consisting of a fine grained, sulphide bearing sediment which transistioned into massive sulphides and finished in an altered footwall stringer zone.
CHDD002 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 and these sediments showed evidence of folding and thrusting.

DHEM Results
Modelling of the DHEM data from CHDD001 and CHDD002 indicates the following key points:
-
CHDD001 intersected the fringe of the upper plate, which now appears to sit further south;
-
The upper zone in CHDD002 is connected to the upper plate drilled by CHDD001, forming a stacked lode;
-
Logging and DHEM indicate that the pyrrhotite-chalcopyrite Cu rich zones are more conductive, while Zn-Pb produces a weaker EM anomaly;
-
The upper plate had an original FLEM response of 900 siemens (Zn-Pb response) and the lower plate 2,050 siemens. The DHEM is now showing the lower plate with 10,000 siemens
==> picture [293 x 257] intentionally omitted <==
==> picture [292 x 284] intentionally omitted <==
(pyrrhotite-chalcopyrite Cu response).
Accordingly, the lower plate remains open, has a strong Cu response, has a stacked lode above it and potentially has additional stacked lodes below it.
Figure 7: Section view of the original FLEM plates (top) and remodelled plates (bottom) showing both holes piercing the original plates as designed (top) and the remodelled upper plate aligning with the upper massive sulphide intercepts (bottom). This highlights the potential for further stacked lodes and that CHDD001 did not pierce the lower plate horizon (bottom).

Chianti-Rufina FLEM Results
Diamond drilling at Chianti confirmed both the VMS style of mineralisation and the approach on how to target massive sulphide bodies within the area. Key learnings include:
-
The massive sulphide mineralisation is comprised of significant amounts of highly magnetic pyrrhotite;
-
The VMS horizon is expressed as a sulphide replacement within a reduced sediment package;
-
The VMS horizon is located between turbiditic sediments and a dominantly mafic to bi-modal volcanic sequence.
In order to maximise our use of the available field season, FLEM surveys were conducted over approximately 40% of the Chianti-Rufina area targeting outcropping gossans, magnetic anomalies and or existing VTEM anomalies within the interpreted VMS horizon.
Six discrete late time FLEM conductors were identified associated with outcropping gossans and magnetic anomalies. Several of the plates are larger than Chianti, further highlighting the potential of this area to host multiple VMS deposits. All FLEM anomalies present priority drill targets in addition to the follow up drilling required at Chianti.

INVESTMENT HIGHLIGHTS
Tarraji-Yampi Ni-Cu-Au Project
Dreadnought controls the second largest land holding in the highly prospective West Kimberley located only 85kms 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-Zn Project is located 160km northwest of Kalgoorlie-Boulder 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 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. Illaara 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 Eastern Goldfields Superterrane of Western Australia. Rocky Dam 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.). 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 • Diamond core sampling intervals were nominally 1m, but within the mineralised horizons they ranged from 0.4 to 1.4 depending on lithological contacts. • At Chianti, HQ quarter core was submitted for analysis. At Grants, HQ and NQ half core was submitted for analysis. • All core was systematically cut slightly offset of the orientation line • All drilled intervals were metre marked with any core loss recorded. Over 95% of core was recovered with most loss in the upper regolith. • QAQC measures included duplicates and inserting blanks and appropriate OREAS standards within the mineralised zones. • Samples were submitted to ALS in Perth for cutting, sample prep, analysis and over range analysis where required. • 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. • Down Hole EM (DHEM) surveyed at 1m to 10m intervals. 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.

Current Exploration • The drill holes are drilled to intersect the modelled mineralised zones at a near perpendicular orientation. However, the orientation of key structures may be locally variable and any relationship to mineralisation has yet to be identified. • FLEM survey was orientated perpendicular to the interpreted lithological strike of the prospective VMS horizon. Historical Exploration •2015 VTEM data was acquired in three blocks on lines orientated 137° (Block A), 164° (Block B) and 000° (Block C), slightly oblique to the strike of the predominant structural/geological trend. •Drilling at 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. |

| 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 were 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. |
| Drill hole information | • A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: oeasting and northing of the drill hole collar oelevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar odip and azimuth of the hole odown hole length and interception depth ohole length. • 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. |
Current Exploration • Refer to table in the report. Historical Exploration • Drilling was completed in the 1950s and 1970s and limited information is available. • Drill collar locations are not visible on the surface and have not been verified. • Locations have been georeferenced from historical mapping and drill plans. . |
| 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 • Exploration assay results are reported where the assays are >0.1% Cu, Pb or Zn or >0.1g/t Au over a geological interval. • No top cutting was used • Length weighted averages are used for any non-uniform intersection sample lengths. Length weighted average is (sum produce of interval x corresponding interval grade %) divided by the sum of interval length. • No metal equivilants values are used for reporting exploration results. 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. |
| 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. |
Current Exploration • All copper, lead zinc values >0.1% and all gold values >0.1g/t are reported in the tables in this announcement. Historical Exploration • All collar locations have been shown in plan view. Further information can be found in WAMEX in reports WMC: A405, A407, A413, A415, A417 ACM: 7506. |
| Other substantive exploration data |
• Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. |
• Rio Tinto Exploration completed a versatile time domain electromagnetic (VTEM) and aeromagnetic survey covering 206 sq km of the Yampi tenements for 901 line kilometres of data using 125 and 250 m line spacing. 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. |
• Additional FLEM surveys will be carried out over the remaining prospective VMS horizon • Surface geochemical orientation surveys are pending to assess the suitability of soil sampling to assist in targeting mineralisation • All targets will be ranked and priority targets drill tested in 2020. |
