HIGHLIGHTS
WONGAN HILLS – targeting Volcanic-Hosted Massive Sulphides (VHMS) base metal mineralisation
-
A single “Slimline RC” drill hole (20WHRC001) beneath copper sulphide mineralisation from previous air core drilling, intersected a zone of anomalous copper - 10m @ 465ppm Cu (from 55-65m, 5m composites) with elevated, Bi, W, and Au (see Table 1) - 1m re-assays to follow.
-
This result, and on-going compilation and interpretation continue to support a VHMS model with follow-up Down Hole Electro Magnetic surveying (DHEM) and deeper drill testing planned.
BROMUS SOUTH – new project for gold and nickel
- Air core drilling to commence at Bromus South in the 1[st] half of this calendar year, targeting a sheared, granite-greenstone contact and an historical gold-in-soil anomaly, subject to access following extensive bush fires in the Norseman area since December 2019.
NORTH TUCKABIANNA – targeting (VHMS) base metal mineralisation
- 2 RC drill holes have been planned to test DHEM anomalies in the Eelya Felsic Complex – at a prospect just east of known base metal mineralisation at the Colonel Prospect (Cyprium Metals Limited, ASX:CYM).
BARLEE – new project for gold
-
Field reconnaissance completed at two contiguous exploration licence applications that stretch from 10 – 55 km SSE of the Penny West Gold deposit.
-
Regolith mapping and prospecting on existing tracks confirmed elongate, ~5km long aeromagnetic anomaly (high), is a sheared amphibolite at a granite contact marking a prime target for follow-up exploration upon tenement grant.

WONGAN HILLS PROJECT, E’s 70/4882, 5162 and 5201, (Cullen 90% - Tregor Pty Ltd 10%): ~180 km north-east of Perth, base metals and gold project
A single “Slimline RC” drill hole was completed in early January on-section west of 19WAC48 - 6593100mN (Figs. 1 and 2) and to allow for follow-up Down Hole Electro Magnetic surveying (DHEM). Interpretation of the drill hole data onsection indicates thin, steeply - dipping zones of hydrothermal alteration (quartzepidote) with traces to low levels (1-2%) of sulphides (including chalcopyrite, pyrite and pyrrhotite). The hole intersected 10m @ 465ppm Cu (from 55-65m, 5m composites) with elevated, Bi, W, and Au (see Table 1) - 1m re-assays to follow.
These alteration-sulphide zones have the same pathfinder geochemical characteristics of the large laterite anomaly, which first attracted Cullen to the target area. However, in Cullen’s opinion, given the size and strength of the CHI3 laterite anomaly ( CHI-3 = As+3Sb+10Bi+10Cd+10In+3Mo+30Ag+30Sn), a more significant sulphide source(s) remains to be discovered (Fig.1).

Cullen Resources Limited Quarterly Report – December 2019
It is possible that the mainly mafic lithologies intersected to date are the hanging wall stratigraphy of a VHMS system and that the footwall stratigraphy, which may include felsic volcanics, lies further east.
DHEM surveying and deeper drilling (RC/diamond, ~1000m with EIS funding) will proceed, following heritage surveying and drill rig sourcing, to test:
-
On-section of the interpreted, west to steeply-dipping anomalous copper zones (package true thickness ~75m) around 19WAC48 on 6593100mN to the east and west and thereafter;
-
South along the target trend (“Prospective Corridor”) of VTEM anomalies and air core copper anomalies Cullen has previously reported (Figs.1 and 2).

BARLEE PROJECT - ELA’s 77/2606, 57/1135 (Cullen 100%)
Cullen holds two contiguous applications totaling ~350sq km from 10 - 55 km SSE of the Penny West Gold deposit and the Youanmi greenstone belt, towards the NW tip of the Marda-Diemals greenstone belt (Fig.4). The applications cover significant strike previously underexplored strike lengths of interpreted shear zones and numerous elongate and/or folded aeromagnetic anomalies (highs) which appear to be intercalated amphibolite within the granite terrane. A reconnaissance field review, regolith mapping and orientation soil sampling were completed in December 2019. This work, via existing access tracks, confirmed sheared amphibolite – granite contacts and parallel quartz veining occurs in target areas.
The first of these applications is anticipated to be approved in March 2020 to allow for exploration, including systematic soil sampling and first pass air core drilling to commence.

NORTH TUCKABIANNA PROJECT, E20/714 - Cullen 100%
Cullen holds E20/714 centered ~30km east of Cue, in the Murchison Region of Western Australia (Fig. 6). The tenement lies north along strike of historical gold deposits that make up the “Tuckabianna Gold Trend”, and is on-strike of the Hollandaire copper resource (see ASX:CYM, 18-7-2019) - Fig. 7. Despite several historical air core drilling campaigns by Cullen and others, in Cullen’s opinion, large tracts of prospective stratigraphy and strike extensive shear zones remain to be fully tested.
Cullen has completed data compilation of the geological setting of VTEM anomalies along strike to the east of Cyprium’s (ASX:CYM) Colonel Prospect. Using mapping and drilling results from 1970’s exploration programs, Cullen has compiled a plan which suggests a target stratigraphic horizon for base metal mineralisation exists as a “synform” and further exploration is warranted.
In particular, Cullen’s previous RC drilling of the strong VTEM anomaly (TNRC13,14,15) did not explain the source of the anomaly and a downhole conductor remains to be tested at this position – two follow-up RC drillholes planned (see Fig. 5 below).

BROMUS SOUTH - Targeting untested gold-in-auger soil anomaly near Norseman, W.A. (Cullen 100%)
Cullen’s E63/1894, approximately 100 sq. kms, is centered 20km SW of Norseman in the Eastern Goldfields of W.A . The tenement includes the “Bromus South” gold prospect within a mixed granite-greenstone terrane (as interpreted by Cullen from aeromagnetic images) and is prospective for gold, and lithium in pegmatites. A low-level, gold-in-auger anomaly (to 8.4ppb), approximately 4.6km long and up to 600m wide (mainly sandplain regolith), was determined by previous explorers (see References below). This anomaly is untested and appears to parallel a granitegreenstone contact. Southern Geoscience Consultants (SGC) has completed processing and imaging of aeromagnetics data. A structural interpretation is in progress to identify favourable structural settings for mineralisation within the gold anomaly. Cullen has applied for a new exploration licence along the western margin of E63/1894.

Data description as required by the 2012 JORC Code - Section 1 and Section 2 of Table 1 RC Drilling – E70/4882
Section 1 Sampling techniques and data
| 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. One hole for 99m was completed – E70/4882. |
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used |
The collar position 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. Drilling was used to obtain one metre samples delivered through a cyclone. The 1m sample was placed in plastic bags and from each drill bag, 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 laboratoryMinanalyticalfor 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.). |
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 |
Sample recovery was assessed visually and adverse recovery recorded. The samples were generally dry, a few were damp, and showed little (<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 hole was kept dry and there was no significant loss/gain of material introducing a sample bias. |

Cullen Resources Limited Quarterly Report – December 2019
| 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. |
|
|---|---|---|---|
| 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 hole 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 - no core taken. | |
| 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. 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 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. |
||
| 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 and primarily aimed at establishing bedrock mineralisation style and type beneath air core anomalies. |
||
| 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. |

| 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. |
|
| Specification of the grid system used. | The grid are in UTM grid GDA94, Zone50 | ||
| 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 of air core anomalies. | |
| 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 by drilling was composited into 5m intervals . |

| 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 a geochemical and geological target, to assist in mapping, and to test for mineralisation below previous anomalies. The drill orientation was easterly (090°). 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 samples are handled, transported and delivered to the laboratory by Cullen staff. All samples were accounted for. |
|
| Audits or reviews |
The results of and audits or reviews of samplingtechniques and data. |
No audits or reviews of sampling techniques and data have been conducted to date. |
|
| Section 2 Reporting of exploration results | |||
| Mineral tenements and land tenure status |
Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interest, historical sites, wilderness or national park and environmental settings. |
The drill target located on E70/4882 is 90% owned by Cullen Exploration Pty Ltd (a wholly-owned subsidiary of Cullen Resources Limited). Cullen has completed a review of heritage sites, and found no issues. Particular environmental settings have been considered when planning drilling. |
|
| The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. |
The tenure is secure and in good standing at the time of writing. |
||
| Exploration done by other parties |
Acknowledgement and appraisal of exploration by other parties. |
There has been previous drilling by Cullen in the general area of this current programme. |
|
| Geology | Deposit type, geological settings and style of mineralisation. |
The targeted mineralisation is volcanic-hosted base metal,type Cu-Au mineralisation |

| Drill hole information |
A summary of all information material for the understanding of the exploration results including a tabulation of the following information for all Material drill holes: |
||
| · E_asting and northing of the drill_ hole collar |
See included table | ||
| ·Elevation or RL (Reduced level- elevation above sea level in metres)and the drill hole collar |

| ·Dip and azimuth of the hole | ||
|---|---|---|
| ·Down hole length and interception depth |
||
| ·Hole 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 whythis is the case. |
See included table | |
| 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. |
See included table |
| 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. |
Drilling was at -60 degree angles to test previous air core anomalies target. The stratigraphy encountered in drilling appears to be dipping to the west at a high angle or is near vertical, and any mineralisation intercepts are likely to overstate 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 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. |

| 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. |
See included figures where current reported data shown together with interpretation of previous drill hole information. There are currently no other exploration data that appear meaningful in the context of the reported results. |
| Further work | The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling). |
Further work, including air core, RC and/or diamond drilling, and DHEM has been planned. |
| Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, providing this information is not commerciallysensitive. |
