HIGHLIGHTS
Mt Stuart Iron Ore Joint Venture (MSIOJV), West Pilbara - Cullen 30% iron ore rights
-
The MSIOJV owns the Catho Well channel iron ore deposit (CID) – one of four starter pits for the proposed West Pilbara Iron Ore Project - Stage 1 (WPIOP), a 30 Mtpa project to be developed by the APIJV (based upon a 2010 Feasibility Study). Cullen Exploration Pty Limited, a wholly-owned subsidiary of Cullen Resources Limited (Cullen), is contributing funds and maintaining its 30% participating interest in the Mt Stuart Iron Ore Joint Venture (MSIOJV). The participants in the APIJV are: Aquila Steel Pty Ltd (a subsidiary of Aquila Resources Limited) 50%, and AMCI (IO) Pty Ltd 50%.
-
Cullen’s ownership of iron ore produced from Catho Well, under one scenario, is ~1.5Mtpa for a 14 year mine life derived from the Catho Well Ore Reserve of 70Mt @ 54.81% Fe (JORC 2004 compliant) – see Cullen’s ASX announcements of 14 December 2010; and 7 June 2012.
-
Cullen anticipates new momentum towards a development decision for the proposed West Pilbara Iron Ore Project, to include mining of Cullen’s ore in the Catho Well CID, in the wake of the successful takeover of Aquila Resources Limited by Baosteel Resources Australia Pty Ltd (Baosteel) and Aurizon Operations Limited (Aurizon).
Wyloo Iron Ore Joint Venture, West Pilbara - Cullen 49% of iron ore rights
- Drilling is planned for the coming Quarter at the Wyloo North and Wyloo South prospects (Fortescue Mining Group Ltd, Manager, earning 80% in iron ore rights)

Cullen Resources Limited Quarterly Report for the period ending 30 June 2014
Mt Eureka, nickel and gold project, North Eastern Goldfields - Cullen 100%
-
A further phase of RC drilling (9 holes for 1502m, MERC 126-134, and deepening of MERC121, Table 1, page 10) was completed in July, testing various targets at the Doyles and Silverbark North nickel sulphide prospects and elsewhere. Ni, Cu and Au assays for 5-metre composite samples are pending. Geological logging indicates no significant Ni sulphide mineralisation associated with the ultramafics intersected. Of the four EM anomalies tested: two were explained as black shale/pyritic sediments; two were pyritic-pyrrhotitic-quartz veined structures in basalt and possibly prospective for gold mineralisation. Other holes tested ultramafics and below anomalous geochemistry in ultramafics, and a magnetic anomaly.
-
On-going geological mapping and prospecting of nickel sulphide targets at Mt Eureka has underlined the AK47 prospect area, the Central Ultramafics basal contact, and the Silverbark North BIF contacts – both east and west – as the priorities for further exploration and drill testing

MT EUREKA, NORTH EASTERN GOLDFIELDS, W.A. – Gold and Nickel
Cullen holds 100% of approximately 650km[2] of approved tenure* in the Mt Eureka Greenstone Belt in the North Eastern Goldfields of Western Australia which includes multiple targets for nickel sulphides and gold. The high nickel prospectivity of Cullen’s ground is confirmed by the discovery of nickel sulphides by Rox Resources Limited (Rox) at Camelwood and Cannonball – Musket (Fisher East Project), located a few kilometres along strike to the south of Cullen’s tenement boundary (Rox ASX release, ASX: RXL of 3/10/2013 describes the maiden mineral resource for Camelwood and ASX release of 10/1/2014 describes discoveries at Cannonball and Musket).
In early July 2014, Cullen commenced a further program of RC drilling, which had been suspended in early May due to heavy rain, and completed on the 14 July (9 holes for 1502 m, including deepening of MERC121). This drilling continued Cullen’s systematic exploration and evaluation of various EM targets and ultramafic trends for nickel sulphides, focused on targets in the stratigraphic corridor along strike of and commencing ~3km north of the Camelwood nickel mineralisation. The program also included reconnaissance drill testing of EM targets on the western margin of the greenstone belt, which intersected pyritic metasediments (MERC129 and 130) at modelled EM plate positions downhole, and MERC133 which intersected meta-sediments and mafic rocks at the Doyles east prospect (see Figures).

Cullen Resources Limited Quarterly Report for the period ending 30 June 2014
DOYLES NICKEL PROSPECT
This “Doyles ultramafic trend” is coincident with a trend of “weak” bedrock conductors interpreted from Cullen’s ground EM, but not modeled, which are generally untested both along strike and in fresh rock. Recent drilling (MERC134 and MERC121 deepened) tested below shallow, anomalous nickel sections of ultramafic but did not intersect any visible Ni sulphide mineralisation. Drilling of the magnetic anomaly under cover east of the main Doyles ultramafic trend, interpreted to be an ultramafic close to the greenstone-granite contact, indicates the magnetic signature is most likely related to meta-sediments and meta-basalts (MERC133).
SILVERBARK NORTH NICKEL PROSPECT
This prospect comprises a series of VTEM and ground EM modeled conductors stretching over 1km in Cullen’s ground (E1637). Cullen has only completed an effective test of one of the modeled conductor plates at Silverbark North; in a previous RC programme (MERC107). However, the VTEM and ground EM anomalous responses are multiple both along strike and across the metasediment stratigraphy and the western contact (hanging wall) of the mixed BIF/black shale package remains largely untested. This contact may host massive nickel sulphides where intersected by any overlying ultramafic. There are two VTEM anomalies coincident with this stratigraphic position which warrants drill testing (see figures).
Drilling completed in the most recent programme targeted modelled EM conductor plates located further to the west of the Silverbark North VTEM/ground EM trend mentioned above (see Figures). This drilling intersected: quartz-pyrite-pyrrhotite zones in meta-basalts at modelled EM plate positions down hole (MERC 126, 127); meta-basalt (MERC 131 and 132); and ultramafic without visible sulphide (MERC 128).
Assay data is pending for all drillholes - MERC 126-134, and the deepened section of MERC121.
FOLLOW-UP PROGRAMMES FOR NICKEL
Cullen’s next round of exploration at Mt Eureka is planned to include (see Figures):
-
follow-up RC drilling of VTEM anomalies on the western margin of the Silverbark North BIF/black shale – possibly coincident with an ultramafic contact;
-
Prospecting of the interpreted basal contact of the Central ultramafic sequence , and an RC drill hole designed to intersect the base of these ultramafic strata on section to the west of MERC 103 – interpreted to be a prospective shale/ultramafic contact;
-
ground EM surveying around the AK47 prospect; and,
-
first pass drill testing, of ground EM anomalies at the Wonganoo Prospect (E53/1611).

EASTERN GOLDFIELDS, W.A. – Gold / Nickel
KILLALOE JV– EL63/1018, 1199 and PLs Matsa Resources Limited 80%; Cullen 20% free carried interest
During the Quarter, Cullen reported to the ASX in relation to the exploration activities completed by Matsa Resources Limited (Matsa), the JV Manager. These announcements described the intersection of narrow zones of semi-massive, and disseminated sulphides in komatiite at the “Hanging Wall Gossan” nickel prospect (diamond drill-hole 14KLDH01 – see CUL: ASX, 17 June 2014). Down hole surveying of this hole identified two strong off-hole conductors (CUL: ASX, 20 June ASX).
Thereafter, Matsa reported that ground EM surveying and full assessment of all existing exploration data for the prospect would be undertaken to allow for the design of a follow-up drill programme at the Hanging Wall Gossan prospect (MAT: ASX, 23 June 2014).
==> picture [335 x 413] intentionally omitted <==
In addition, Cullen suggests there is significant nickel sulphide prospectivity along the western contact of the Eastern Ultramafic Belt (see Figure above). Cullen interprets this contact is the southern strike extent of the basal contact of ultramafics which host the Taipan nickel sulphide discovery of Sirius Resources Limited (SIR: ASX announcement of 16 July, 2014) in their Polar Bear Project.

Cullen Resources Limited Quarterly Report for the period ending 30 June 2014
Data description as required by the 2012 JORC Code - Section 1 and Section 2 of Table 1
| Section 1 Sampling techniques and data | Section 1 Sampling techniques and data | |
|---|---|---|
| Criteria | JORC Code explanation | Comments re RC drilling programme |
| Sampling technique |
Nature and quality of sampling (egg 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 broadmeaning ofsampling. |
Sampling was by reverse circulation (RC) drilling testing individual EM conductors and geological targets. Nine RC holes were drilled and one previously drilled hole was deepened for a total of 1502m. |
| 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 a handheld GPS with an approximate accuracy of ±3m; down-hole surveys were completed. |
|
| 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 (e.g. submarine nodules) may warrant disclosure ofdetailedinformation. |
RC drilling was used to obtain one metre samples from which a 3-4kg sub-sample was taken using a cone splitter. The sub-sample together with the remainder of the 1-m sample was placed on the ground. From each drill spoil pile, a c. 400g sample was then collected using a scoop; five of such 1-m samples were combined into one composite sample. The composite samples (2- 3kg) were sent to an accredited Perth laboratory 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.). |
Drilling was by reverse circulation using a 140mm diameter 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 the recovery recorded. The samples were generally dry or 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 spreadsheets. Cyclone, splitter and buckets were cleaned regularly and thoroughly (between rod changes and after completion of each drill hole) to avoid cross contamination. |
|
| 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 kept dry and within the targeted zones, there was no significant loss/gain of material introducing a sample bias. |
12
Cullen Resources Limited Quarterly Report for the period ending 30 June 2014
| Logging | Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. |
All samples were 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 mineralization) and semi-quantitative (visual estimation of sulphide content, quartz veining, alteration etc.). |
|
| The total length and percentage of the relevant intersections logged |
All drill holes were 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 split dry using a cone splitter attached to the drill rig. Composite samples were taken using a sampling scoop. |
|
| For all sample types, quality and appropriateness of the sample preparation technique. |
All samples are pulverised using Essa LM1, LM2 or LM5 grinding mills determined by the size of the sample. Dry crushed or fine samples are pulverized to produce a homogenous and representative sub-sample for analysis. A grind quality target of 85% passing 75μm is established and is relative to sample size, type and hardness. However the nature (hardness) of some samples is such that this may not always be achievable using standard preparation protocols. In such case an additional 2nd stage grinding is applied where a sub split is taken and further ground to ensure the assay pulp passes QC. In extreme cases, 85% passing 75 micron may not be achievable and thus cannot be guaranteed for all samples. Low chrome steel bowls are used for pulverising which could impart trace levels ofcontaminants suchas Cr,Fe andMo. |
|
| 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. |
|
| 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. |
For quality control of the field sampling, duplicate samples of the 5-m composites are taken at the rate of 1 per 20. |
|
| 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 exploratory and primarily aimed at establishing the presence of mineralisation. |
|
| The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. |
For all 5-m composite samples, a 10g aliquot is digested using aqua regia. Analysis for gold is by AAS; Cu and Ni are analysed using ICP-OES. 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 containedtargetelements. |

| Quality of assay data and laboratory tests |
Nature of quality control procedures adopted (egg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have beenestablished. |
International standards, blanks and duplicates are inserted by the laboratory. |
| Verification of sampling and assaying |
The verification of significant intersections by either independent or alternative company personnel. |
Cullen staff (Chief Geologist and Managing Director) has visually inspected the samples and sampling procedures. |
| The use of twinned holes | No twinned holes drilled to date | |
| 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 any adjustment to assay data. | No adjustments are made to assay data other than the replacement of ‘less than detection limit’ with a value of halfoftherespective detection limit. |
|
| 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. |
All drill collar surveys are by handheld GPS. Several measurements (2-3) at different times are averaged; the estimated error is ±3m. |
| Specification of the grid system used. | The grid coordinates for the Silverbark North and Doyle's targets are in GDA94, Zone 51 |
|
| Quality and adequacy of topographic control. |
There is currently no topographic control and the RL is a nominal 500m for all drill holes. |
|
| Data spacing and distribution |
Data spacing for reporting of Exploration Results. |
The drilling tested geological and geophysical targets, several kilometers apart. Some of the targets were tested by a single hole others were drilled along a traverse with holes spaced20-80mapart. |
| 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 exploratory and not designed to satisfy requirements for mineral reserve estimations. |
|
| Whether sample compositing has been applied. |
The drill spoil generated by the RC drilling was composited into one metre 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. |
The drilling is exploratory only and designed to test geophysical and geological targets for the presence of nickel mineralisation at depth. The drill orientation was generally to the west (257 or 270 degrees) and at an angle of -60 degrees with the exception of MERC133 which targeted a magnetic high east of Doyles at a dip of -90 degrees. No visible Ni sulphide mineralisation has been encountered and hence 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. |
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 mineralization related to geophysical modeling has not been established yet (single holes only) but based on the geophysical modeled plates it is likely that the drilled intersections overestimate the true thickness of any intersected mineralisation. |

| The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operatein 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 no previous drilling at Silverbark North by other parties than Cullen and only limited historic drilling at the Doyles Prospect (Dominion Mining,1994). |
||
| Geology | Deposit type, geological settings and style of mineralisation. |
The targeted mineralisation is komatiite-hosted and/orassociatedArchean nickelsulphide. |

Quarterly Report for the period ending 30 June 2014
Cullen Resources Limited
| 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. |
No analytical results reported - all assays pending. |
|---|---|---|
| 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 indetail. |
No analytical results reported - all assays pending. | |
| The assumptions used for any reporting of metal equivalent values should be clearly stated. |
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 60-90 degree angles to test geophysical target plates derived from EM ground surveys and prospective geological settings. The stratigraphy encountered in drilling is variably dipping to the east 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 known yet. |
|
| 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’) |
No mineralized intervals reported in this release – all assays pending. |
|
| 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 sectionalviews.. |
see attached table/figures |
| 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 attached 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 containing substances. |
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 (e.g. tests for lateral extensions or depth extensions or large-scale step-out drilling). |
Further work, including RC drilling, and ground and down hole geophysical surveys, is planned. |
| Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, providing this information is not commercially sensitive. |
