HIGHLIGHTS
WONGAN HILLS PROJECT - targeting Volcanic-Hosted Massive Sulphide (VHMS) mineralisation (Cullen 90%)
-
Soil sampling, and reverse circulation and air core drilling completed – all assays pending.
-
Drilling tested ground EM conductors for VHMS mineralisation; soil sampling across base metal-gold targets and historical Pt-Pd-Au soil anomalies.
-
At Rupert, drilling intersected semi-massive to massive pyrite with minor pyrrhotite in shale and siltstone at mafic volcanics-sediment interfaces. Presence of felsic metasediments supports a VHMS model.
-
Wongan and Louise Prospect trends are dominated by mafic lithologies with probable structural control to known copper-gold mineralisation.
BARLEE PROJECT - targeting Penny West - type Gold (Cullen 100%)
- 579 auger soil samples collected, targeting magnetic/structural anomalies within E77/2606 - all assays pending.
OVERVIEW
The December Quarter focused on drilling key targets at the Wongan Hills Project. This work supports VHMS prospectivity along the Rupert Trend where follow-up ground EM surveying of the untested southern part of this trend is planned to commence. Soil sampling was also completed at Wongan Hills along the southern extension of the Rupert Trend, and elsewhere within E4882 to follow-up historical Pt-Pd-Au soil anomalies. This project will be a focus for the remainder of this current Quarter prior to the re-start of wheat farming activities in April.
Also in the current Quarter, soil sampling and reconnaissance mapping programs, will be undertaken at the Barlee and Bromus gold projects, with air core drilling subject to heritage clearances.

Cullen has applied for a Reservation Licence of approximately 200 sq. km for a 2 year term. “Aakenus” surrounds Cullen’s Katajavaara Exploration Permit application in the Central Lapland Greenstone Belt. The region has seen substantial uplift in exploration activity with recent company gold discoveries in the region including: S2R (ASX), and Rupert Resources (RUP.V). Aakenus surrounds several known gold and copper occurrences, including Sattopora and Rikkonas, and includes part of the regionally-significant Sirrka shear zone and strike-extensive, prospective stratigraphy.

Quarterly Report - December 2020
WONGAN HILLS PROJECT, EL’s 70/4882 and 5162, ELA 70/5414 (Cullen 90% - Tregor Pty Ltd 10%): ~150 km north-east of Perth, base metals and gold project
SUMMARY
-
A program of 3 Reverse Circulation (RC) holes for 456m, and 13 Air core (AC) holes for 552m was completed in December. (The air core program was interrupted in mid-December following a rig breakdown and recommenced in January, 2021, with a further 22 holes for 1151m completed – all assays pending).
-
The two RC holes at Rupert (ASX:CUL, 22-6 and 15-7-2020), tested the northern and southern ground EM (Electromagnetic) conductor plates below historic gold and silver soil geochemistry.
-
Both of these holes intersected sections of semi-massive to massive pyrite with minor pyrrhotite in shale and siltstone at mafic volcanics-sediment interfaces, from down-hole depths of 141m (3m thick) and 115m (5m thick).
-
These sulphide intersections are interpreted to be the source of the modeled conductors in both cases and, from the position of mapped VTEM responses, may be two separate stratigraphic horizons or a single faulted unit.
-
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. In-fill soil sampling was completed in January with assays pending.
-
A number of air core holes was completed in January at the southern end of the Louise prospect, with assays pending.
-
One RC hole was completed at Wongan to test below one of the better bottom-of-hole zinc with copper anomalies from previous air core drilling.
-
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. (Subsequent to the Quarter, in January 2021, a program of soil sampling was completed within E4882 across the interpreted northern margin of a major gravity anomaly and historical Pt-Pd-Au soil anomalies, the Pioneer Prospect - with assays pending.)

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, near Bindi Bindi (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 - December 2020
Cullen currently exploring four prospects: “Wongan”, “Rupert” “Louise” and “Pioneer”.
Wongan Prospect - RC drilling
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. Ground EM could not resolve or refine the main VTEM responses 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.
RC hole ( 20WHRC005 ) completed in December, tested below one of the better bottom-of-hole zinc with copper anomalies at Wongan from previous air core drilling (January 2019). It intersected mafic volcanics with minor disseminated pyrite-pyrrhotite in an interpreted fault zone. These data, together with the sectional data at 6593100mN and greenstone belt-wide aeromagnetic interpretations (WAMEX, A47022), support Cullen’s interpretation that coppergold mineralisation discovered to date at the Wongan Prospect may be structurally controlled. Major North-South faulting has been interpreted in parallel to the Wongan Prospect VTEM corridor/prospect trend.

Rupert Prospect - RC and AC drilling
“Rupert”, approximately 3km to the east of “Wongan”, is an untested VHMS target trend with coincident ground EM conductors and associated geochemical anomalies, and favorable geology (ASX:CUL, 22-6-2020 and 15-7-2020). RC drilling in December ( 20WHRC003 and 004 ) tested the two ground EM plates as described above.
Air core drilling traverses were also completed at Rupert to establish and test the stratigraphy which hosts the ground EM anomalies, discovered to be pyrite - pyrrhotite bearing black shales/siltstones. Drilling intersected mafics and quartzites along the southern traverse across the EM plate, whereas the northern traverse intersected some quartz-mica-schists (felsic metasediments) to the east of the EM anomaly (interpreted to be stratigraphically below the shale horizon). These are the only felsic derived lithologies intersected to date in the Project area, and concur with historical geological interpretation maps (Fig.5).

Louise Prospect - AC drilling
A number of air core holes were drilled at the southern end of the Louise prospect subsequent to the end of the Quarter. Drilling intersected unaltered mafics and fresh felsic intrusive. The historical Louise soil anomaly forms a coherent NNE trend parallel to stratigraphy (magnetics interpretation), lying west of the Wongan laterite anomaly. The southern portion of the Louise anomaly and the contact with an nearby interpreted felsic intrusive - a possible sources of metals - was the target of recent air core and drilling, with assays pending (Fig.5).

Quarterly Report - December 2020
Soil sampling - southern Rupert
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. Infill soil sampling for multi-element analyses was completed in January to the south, and further ground EM surveying and/or air core drilling are planned (Fig.6).

Soil sampling - Pioneer Prospect, historical Pt, Pd, Au soil anomalies
Five soil samples were collected by a previous explorer within E5162 in 2015. Samples were from road side Reserves, of 200-300g, taken from 30-50cm depth, and sieved to -1.6mm. Assays were by aqua regia digest with ICP-MS finish. The results reported (Table 1 below) show anomalous Pd, Pt, Au, and elevated levels of several other metals (all ppm except where shown).

The two most anomalous soil samples are 500m apart and spatially associated with a prominent, large gravity high. There are no bedrock exposures in the vicinity of the soil samples or the general area of the gravity anomaly. Cullen has completed soil sampling traverses across the line of these historical reconnaissance samples and a number of traverses to the north, across the paddock (200 to 400m x 50m spacing (Fig.6) with assays pending.

Quarterly Report - December 2020
Data description as required by the 2012 JORC Code - Section 1 and Section 2 of Table 1 RC and Air Core Drilling– E70/4882
| 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 Reverse Circulation (RC) and Air Core (AC) drilling testing bedrock and interpreted geological and/or geophysical targets for gold mineralisation and/or base metals. 3 RC holes for 456m and 13 AC holes for 552m. |
| 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. 1m RC samples were collected in calico bags, and stored. 1 m air core samples were placed on the ground. RC 1m samples were also collected in plastic bags and, a ~500g sample was collected using a scoop and five of such 1m samples were combined into one 5m composite samples. 5m composite air core samples were collected similarly. 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 using a 5.5in, face sampling hammer bit. AC drilling using a 4.5 inch 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. |
20
Quarterly Report - December 2020
| Whether logging is qualitative or quantitative in nature. Core (or costean, channel etc.) photography. |
Logging of rock chips was qualitative (lithology, type of mineralisation) and semi-quantitative (visual estimation of sulphide content, quartz veining, alteration etc.). |
|
|---|---|---|
| The total length and percentage of the relevant intersections logged |
Drill holes logged in full. | |
| Sub- sampling techniques and sample preparation |
If core, whether cut or sawn and whether quarter, half or all core taken. |
Not applicable (N/A) |
| 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 to be 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. Planned analysis of all drill 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. |
|
| 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 to be 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 thiese drilling programmes, which are reconnaissance only, primarily aimed at establishing bedrock mineralisation and source of EM anomalies (RC drilling) and geology presence of favourable shear structures forgold and base metals(air core). |

N/A | |
| 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. |
N/A | |
| The assumptions used for any reporting of metal equivalent values should be clearlystated. |
N/A | |
| 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 west at a moderate angle (~50°). No mineralisation reported – assays pending. |
| If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. |
N/A | |
| 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’) |
N/A | |
| 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 |
