HIGHLIGHTS
WONGAN HILLS PROJECT - targeting Volcanic-Hosted Massive Sulphide (VHMS) mineralisation (Cullen 90%)
-
Following the rain-interrupted program (ASX: CUL, 21-8-2020), RC and air core drilling are planned to commence in December, subject to the end of wheat harvest.
-
A new target trend of VTEM, and historical Au, Ag and Cu soil anomalies, is recognised in a stratigraphic corridor to the north of the Rupert Prospect (ASX:CUL, 22-6 and 15-7-2020), with ground EM and/or air core traversing also planned to commence in December.
-
A private land access agreement has been signed to enable exploration to the south of the Rupert Prospect on previously untested coincident VTEM and soil anomalies, commencing in January.
-
Zinc and copper bedrock anomalies in Cullen’s previous air core drilling are coincident with silver anomalies in soils and define a new VHMS target trend named Louise.
-
The large gravity anomaly in the southern part of the E4882, and ELA 70/5414, that adjoins Liontown’s (ASX:LTR) Moora Nickel Project to the east, are under initial investigation for mafic-ultramafic hosted Ni-Cu-PGE mineralisation potential, with mapping, soil sampling and, potentially, air core drilling to follow.
-
Together these developments provide an expanded project area and additional targets that warrants an exploration focus in the coming three months, and especially post the wheat harvest.

Fig.2 Project Location Map
Wongan Hills Project on regional gravity image (1VD) from government database (“Geoview”), hot colours are positive. Regional Exploration Activity and Mineralisation includes : the Nickel-Palladium (Ni-Pd) discovery by Chalice Gold Mines Limited at Julimar (ASX:CHN, 15-4-2020); the Nickel - Copper - PGE mineralisation at Yarawindah being explored by Cassini Resources Limited (see ASX:CZI, 16-4-2020); and exploration results reported by Liontown Resources Limited at their Moora Nickel Project (ASX:LTR;16-4-2020). Thus, industry attention now focussed on what may be an emerging Nickel - Copper - PGE province to the north east of Perth. There is also a notable copper resource near Calingiri (see Caravel Minerals Limited, ASX:CVV, “Caravel Copper Project”) just south of the Wongan Hills project.

Quarterly Report - September 2020
Cullen currently exploring three VHMS prospects: “Wongan”, “Rupert” and “Louise”.
Wongan Prospect – RC drilling to test VTEM anomalies
The Wongan Prospect and its target “Stratigraphic Corridor”, defined by a Golden Grove-type laterite geochemical anomaly and a cluster of VTEM anomalies, has been the focus of exploration to date. This exploration has included: ground EM surveying, and air core, RC and diamond drilling, focused on section 6593100mN beneath the highest values of the laterite anomaly (ASX: CUL, 15-7-2020). Ground EM could not resolve or refine the VTEM response in this area due to the presence of conductive overburden, and DHEM surveying, completed on diamond drill hole 20WHD001 in September, did not detect any near hole conductors.
However, Cullen plans further drilling to depth to the west of current drilling on section 6539100mN (Fig.4). In Cullen’s opinion, the extent of base metal mineralisation discovered to date (ASX:CUL, 15-7-2020) does not account for the intensity of the laterite anomaly in this area nor the VTEM anomalies.

Rupert Prospect – extension ground EM, air core and RC drilling planned
“Rupert”, approximately 3km to the east of “Wongan”, is an important, new, untested VHMS target trend with coincident ground EM conductors and associated geochemical anomalies, and favorable geology (ASX:CUL, 22-6-2020 and 15-72020). Importantly, a recently-negotiated access agreement now permits exploration of the area to the south of the Rupert EM plates, over which there has been minimal previous exploration. An RC drill rig to be employed to test the EM plates as soon as practical after wheat harvesting (Fig.5).
Compilation of historical soil sampling data indicates significant geochemical anomalies (Ag, Au and Cu) with coincident VTEM conductors to the north and south of the modelled EM plates. Ground EM surveying and/or air core drilling are planned (see Figures 5 and 6 following).

Quarterly Report - September 2020
Louise Prospect
The historical Louise soil anomaly (Fig. 6) forms a coherent trend lying west of the Wongan laterite anomaly, and is now regarded as a discrete VHMS target. Higher BLEG silver assays in the southern part of the Louise anomaly form a NNE trend parallel to stratigraphy (magnetics interpretation). Although Cullen’s air core drilling to date indicates thick cover of transported lateritic pisolites, bedrock anomalies of copper and zinc along this silver anomaly trend warrant in-fill air core and potentially, deeper RC drill testing to follow. (The general area of interest is shown as a yellow oval on Figs. 5 and 6). This work is planned for a December start.

BARLEE PROJECT - ELs 77/2606, 57/1135 (Cullen 100%)
The project area extends from 10 - 55 km SSE of the Penny Gold (previously “Penny West”) deposit and the Youanmi greenstone belt, towards the NW tip of the Marda - Diemals greenstone belt (Fig.9). It covers significant strike of underexplored shear zones and numerous elongate and/or folded aeromagnetic anomalies (highs), which are interpreted to be intercalated greenstone within the granite terrane.

NORTH TUCKABIANNA PROJECT, E20/714 (Cullen 100%), centered ~30km east of Cue, in the Murchison Region, gold and base metals
Cullen holds E20/714 centered ~30km east of Cue, in the Murchison Region of Western Australia (Fig.11). Cullen completed two “Slimline” RC holes (223m) to test DHEM anomalies for base metal sulphides, ~2.5km along strike to the east of Cyprium’s Colonel Prospect and north east of its Mt Eelya Prospect (ASX: CYM 8-7-2020). Both holes intersected thick zones of pyritisation (2-50% per metre, in down hole sections up to ~20m thick) in felsic volcanics. This pyritisation is coincident with the DHEM plate in both holes, and is clearly the cause of the two EM anomalies targeted. Only geochemically anomalous base metals assays ( best 35m @ 310ppm Cu downhole – TNRC19 ) were returned.
The felsic volcanics intersected comprise sheared andesite and quartz mica schists in contact with mafic volcanics to the south, and intermediate tuffs and lavas to the north. The strata are interpreted to be on-strike of the Colonel mineralisation and they appear to continue eastwards, as indicated by air magnetics images. Further exploration along trend to the east is under consideration.
A short reconnaissance air core program (21 holes for 793m) was also completed to test interpreted N-S trending shear zones/faults, which are at a high-angle to the “Tuckabianna Gold Trend”. Zone of shearing and some quartz veining were intersected in several holes supporting the interpretation of the N-S trending structures, but no significant gold assays (5m composite > 0.1g/t Au) were returned. There are numerous other N-S structures and their intersections with stratigraphic boundaries will be reviewed as potential additional gold targets (Fig.11).

Data description as required by the 2012 JORC Code - Section 1 and Section 2 of Table 1 RC and Air Core Drilling– E20/714
| Section 1 Sampling techniques and data | Section 1 Sampling techniques and data | Section 1 Sampling techniques and data |
|---|---|---|
| Criteria | JORC Code explanation | Comments |
| Sampling technique |
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 XRF instruments, etc.). These examples should not be taken as limiting the broad meaningof sampling. |
Sampling was by “Slim Line RC” (RC) drilling testing bedrock and interpreted geological and/or geophysical targets for gold mineralisation and/or base metals. Two RC holes for 223m, and 21 air core holes for 793m were completed. |
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used |
The collar positions were located using handheld GPS units with an approximate accuracy of +/- 5 m. Drill rig cyclone and sampling tools cleaned regularly during drilling. |
|
| 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 1m samples from which 3kg was pulverised to produce a 30g 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 (eg submarine nodules) may warrant disclosure of detailed information. |
Mineralisation determined qualitatively from rock type, alteration, structure and veining observations. RC and air core drilling was used to obtain one metre samples delivered through a cyclone. The 1m sample was placed on the ground and, a ~500g sample was collected using a scoop and five of such 1m samples were combined into one 5m composite sample. The composite samples (2-3kg) were sent to Perth laboratory Minanalytical for analysis. |
|
| Drilling technique |
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.). |
RC Drilling was by Slim Line RC using a 4.5in, face sampling hammer bit. |
| Drill Sample recovery |
Method of recording and assessing core and chip sample recoveries and results assessed |
RC and air core sample recovery was assessed visually and adverse recovery recorded. The samples were generally dry, a few were damp, and showed some (<10%)variation in volume. |
| Measurements taken to maximise sample recovery and ensure representative nature of the samples. |
The samples were visually checked for recovery, contamination and water content; the results were recorded on log sheets. Cyclone and buckets were cleaned regularly and thoroughly (between rod changes as required and after completion). |
|
| Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. |
The holes were generally kept dry and there was no significant loss/gain of material introducing a sample bias. |
|
| Logging | Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining and metallurgical studies. |
All samples were qualitatively logged by a geologist in order to provide a geological framework for the interpretation of the analytical data. |

| If non-core, whether riffles, tube sampled, rotary split, etc. and whether sampled wet or dry. |
One-metre samples were collected from a cyclone attached to the drill rig into bags or buckets, then emptied on to the ground in rows. Composite samples were taken using a sampling scoop. |
|
| For all sample types, quality and appropriateness of the sample preparation technique. |
All samples are pulverised to produce a homogenous representative sub-sample for analysis. A grind quality target of 85% passing 75μm is established and is relative to sample size, type and hardness. For all samples : Gold (Au), Silver (Ag,) Arsenic (As), Bismuth (Bi) Copper (Cu), Cobalt (Co), Molybdenum (Mo), Nickel (Ni), Lead (Pb), Antimony (Sb), Tellurium (Te), Tungsten (W) and Zinc (Zn)) was analyzed by Aqua Regia digest with ICP-MS finish.(Gold by AAS). |
|
| Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. |
Duplicates certified reference materials and blanks are inserted by the laboratory and reported in the final assay report. Check analyses were also undertaken by the laboratory. |
|
| Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling. |
No field duplicate samples were taken – one metre resampling and duplicating was anticipated for any mineralised intersections. |
|
| Whether sample sizes are appropriate to the grain size of the material being sampled. |
The sample size is considered appropriate for the purpose of this drilling programme, which is reconnaissance only, primarily aimed at establishing bedrock mineralisation and source of EM anomalies (RC drilling) and presence of favourable shear structures forgold(air core). |
|
| The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. |
For all samples, a 25g aliquot is digested using Aqua Regia. Analysis for gold and a range of other trace elements is by ICP-MS or AAS. The aqua regia digestion is considered partial depending on the host of the elements analyzed, but does provide an acceptable level of accuracy for an initial assessment of the contained target elements. |
|
| For geophysical tools, spectrometers, handheld XRF instruments, etc., the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. |

| Documentation of primary data, data entry procedures, data verification, data storage (physically and electronic) protocols. |
All primary geological data are recorded manually on log sheets and transferred into digital format. |
|
| Discuss anyadjustment to assaydata. | No adjustments are made to assaydata aspresented. | |
| Location of data points |
Accuracy and quality of surveys used to locate drill holes (collar and down- hole surveys), trenches, mine workings and other locations used in Mineral Resources estimation. |
Drill collar survey by handheld GPS. Several measurements (2-3) at different times are averaged; the estimated error is +/-5 m. RL was measured by GPS. |

| Quality and adequacy of topographic control. |
There is currently no topographic control and the RL is GPS (+/-5m). |
|
| Data spacing and distribution |
Data spacing for reporting of Exploration Results. |
The drilling tested down dip EM anomalies and interpreted structures. |
| Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Reserve and Ore Re4serve estimation procedure(s) and classifications applied. |
The drilling was reconnaissance and not designed to satisfy requirements for mineral reserve estimations. |
|
| Whether sample compositing has been applied. |
The drill spoil generated was composited into 5m samples. |

Quarterly Report - September 2020
| Orientation of data in relation to geological structure |
Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. |
Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. |
The drilling is reconnaissance level and designed to test geophysical and geological targets, to assist in mapping, and to test for mineralisation below anomalies. The RC drill orientation was northerly (000°), and air core drilling along existing tracks at ~ 270,225,255, or 180°. It is unclear whether the sampling is unbiased or not. |
|---|---|---|---|
| If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
The exact dip of the structures targeted has not been established yet but it is likely that the drilled intersections overestimate the true thickness of any intersected mineralisation. |

| Sample security |
The measures taken to ensure sample security. |
All drilling samples are handled, transported and delivered to the laboratory by Cullen staff. All samples were accounted for. |
|

| Data aggregation methods |
In reporting Exploration results, weighing 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. |
N/A |
| 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. |
See included table | |
| The assumptions used for any reporting of metal equivalent values should be clearlystated. |
No metal equivalents used. | |
| Relationship between mineralisation widths and intercept lengths |
These relationships are particularly important in the reporting of Exploration Results. |
RC and AC Drilling was at -60 degree angles. The stratigraphy encountered in RC drilling appears to be dipping to the south at a moderate angle (~50°) and any mineralisation intercepts are likely to be close to the true width of mineralisation. |
| If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. |
The exact geometry of the mineralisation/intersections is not yet known. |
|
| 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’) |
See Table in report | |
| Diagrams | Appropriate maps and sections (with scales) and tabulations of intercepts would 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. |
See included figures |

Quarterly Report - September 2020
| 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. |
See included Table.. |
|---|---|---|
| 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 containingsubstances. |
N/A – reported previously |
| 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). |
Further work is under consideration. |
| Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, providing this information is not commerciallysensitive. |
