HIGHLIGHTS
-
A total of 53 RC drill-holes were completed into pisolitic ironstone (CID) hosted by the Robe Mesa on the Yarraloola Project.
-
Geological logging identified the upper (outcropping) and lower (subcropping) interval of sub-horizontal pisolitic ironstone with Fe>50% (calcined iron as FeCa>55%) which is a feature of the Robe Mesa in almost all the drill-holes.
-
All assays have been received and samples with Fe>50% (FeCa>55%) are characterised by low phosphorus (<0.05%) and high loss on ignition ( ̴10%).
-
Upper zone mineralisation extends entirely across the surface of the mesa and is up to 28m thick. Intercepts report Fe up to 22m @ 57.3 (Feca @ 63.7%) in YAR147.
-
Subcropping lower zone mineralisation is up to 30m thick but wider intercepts are more localised within a broad channel that underlies the western and central parts of the Robe Mesa. Intercepts report Fe up to 30m @ 55.37% (Feca @ 61.2%) in YAR121.
-
The easterly outcrop and subcrop extension of pisolitic ironstone in the Lower Robe represents a significant target for future exploration drilling
Yarraloola Project
Robe Mesa - Background
During 2014, Coziron Resources Limited (“CZR or Company”) mapped, surface-sampled and completed 25 vertical RC drill-holes for 1562m into part of the Robe Mesa which extends for a length of about 2km and a width of between 400 to 600m on tenements E08/1060 and E08/1686 at the Yarraloola Project (Fig 1). This drilling intersected two intervals of pisolitic iron-stone (CID
1
mineralisation) with grades of Fe>50%. The upper zone outcrops as a cap on the mesa, while the lower zone typically underlies 10 to 20m of silty and sandy material.
Following the initial round of drilling in 2014, Optiro Ltd used the available geological and geochemical data and Surpac to independently generate an Inferred Resource which is summarised in Tables 1 and 2.
Table 1. Robe Mesa – Mineral Resource Estimate at January 2015 – reported above a Fe cut-off grade of 50% .

(Full details of the parameters used to calculate the Inferred Resource model were announced by CZR on the ASX on 3[rd] February 2015.)
Robe Mesa - 2015 Activities and Results
The recently completed 2015 RC programme by Topdrill Pty Ltd on the Robe Mesa (drill-hole locations and a map reported to the ASX on 16[th] August 2015 but included here for completeness) has infilled the 200m spaced drill-holes from the 2014 drilling campaign to approximately 100m intervals (Table 3; Fig 2). The 53 holes for 3374m were each sampled with appropriate duplicates at 1m intervals by a cone splitter attached to the RC drill-rig. The samples, each weighing about 3-5kg, were packed in bulka bags onsite and dispatched using RGR Transport to Bureau Veritas Laboratories in Perth for analysis. After grinding, a representative sample was fused with a sodium borate flux and analysed for a suite of major elements by XRF. Details of the process are contained in Appendix 1.
The purpose of the drilling was to provide a significant increase and confidence in the amount of geological and geochemical data within the confines of the Inferred Resource model which was announced to the ASX on 13[th] February 2015. The material results to date from the 2014 and 2015 drilling programmes can be summarised as follows.
-
The planned depth for all the 2015 RC holes was sufficient to intercept both the upper and lower intervals of pisolitic ironstone and all holes were completed in weathered material derived from the Duck Creek Dolomite.
-
All the holes reported 1m samples with Fe >50% (calcined iron Feca>55%) and all the intercepts that extend over at least 5m in thickness are reported in Table 4.
-
The increased drill-hole density supported the initial geological model, which interpolated mineralisation as being represented by two flat-lying sheets of pisolitic iron-stone separated by silty sandstone (Fig 3 and 4).
-
The thickness of both the upper and lower zone pisolites has remained relatively consistent in adjacent drill-holes.

-
The upper zone of pisolitic iron-stone with Fe>50% that outcrops on the mesa is characterised by stronger development of a goethitic cement, is widely distributed and up to 29m thick (Fig 5).
-
The lower zone of pisolitic iron-stone with Fe>50% which is also up to 30m thick and appears to have lesser amounts of vitreous goethite cement is contained within a slightly asymmetric channel that has the thickest development along the western and northern margins of the drilled prospect (Fig 6).
The Chairman of CZR Mr Adam Sierakowski commented: “The Board is very happy with the results of the recent drilling at the Robe Mesa. The drilling not only confirms the geological model but appears to show there is significant opportunity to increase both the resource tonnage and confidence. Further this exploration success represents only the first of multiple targets of similar geology and scale that exist on the Yarraloola project.
While early days, it appears as if the Robe Mesa could support a stand-alone mining operation, particularly given it is ideally located in proximity to both existing and proposed transportation infrastructure and coastal ports. These elements afford CZR the rare potential to be a commercial iron ore producer even at current depressed iron ore prices.”
Future Work
Following from the RC drilling programme, priority activities to be completed by the Company over the coming weeks include the following.
-
Acquisition of survey control on the surface of the Robe Mesa
-
Complete an independent review of the JORC-compliant Inferred Resource completed with the view of increasing both the tonnage and confidence of the resource.
-
Review the grade distribution and thickness models in detail to determine whether the core of the channel system contains higher grade material.
Results will be announced as they become available.

Appendix 1 – Reporting of exploration results from the Yarraloola Project - JORC 2012 requirements.
| Section 1 Sampling Techniques and Data | Section 1 Sampling Techniques and Data | |
|---|---|---|
| Criteria | JORC Code explanation | Commentary |
| Sampling techniques |
Nature and quality of sampling (eg 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. |
The results presented are derived from a 5.5” reverse circulation drilling programme with continuous down-hole sampling. |
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. |
2-3kg of drill chips are collected during the drilling of each meter in a calico bag from a cone splitter which is attached to the drill-rig. |
|
| 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 (eg ‘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 (eg submarine nodules) may warrant disclosure of detailed information. |
The entire 2-3kg drill-chip sample is crushed, dried and pulverized at Bureau Veritas Laboratories in Perth. Western Australia. A sub sample was fused and the "basic iron-ore suite" of major oxide and selected trace- element analysis was obtained by XRF Spectrometry. |
|
| Drilling techniques |
Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg 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). |
Samples were collected by reverse circulation drilling using a 5.5” face sampling hammer. |
| Drill sample recovery |
Method of recording and assessing core and chip sample recoveries and results assessed. |
The volume of sample derived from each reverse circulation meter drilled is approximately equal. |
| Measures taken to maximise sample recovery and ensure representative nature of the samples. |
Some water is injected into the sample stream during drilling to minimise the loss of fine particles. |
|
| 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 loss of fine material has been minimized during drilling. Sample recovery is regarded as being representative. |
|
| 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. |
Each metre of reverse circulation chips is described geologically for mineralogy, colour and texture. The mineral resource estimate has not been updated in this report. |
| Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. |
Logging is qualitative. | |
| The total length and percentage of the relevant intersections logged. |
Sample intervals from the entire drill hole are logged. |

15
| Sub-sampling techniques and sample preparation |
If core, whether cut or sawn and whether quarter, half or all core taken. |
No core was collected for this study |
|---|---|---|
| If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. |
Reverse circulation drill chip samples are collected from a cone splitter during drilling. |
|
| For all sample types, the nature, quality and appropriateness of the sample preparation technique. |
Reverse circulation drilling is an appropriate method of recovering representative samples though the interval of mineralization. |
|
| Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. |
Appropriate duplicate samples in mineralized intervals are collected and analysed to ensure representivity. |
|
| 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. |
The reverse circulation method samples continuously and the splitter selects a representative proportion of the sample and provides an indication of compositional variations associated with each lithology or mineralized interval. |
|
| Whether sample sizes are appropriate to the grain size of the material being sampled. |
The 2-3kg of homogenized chips recovered is sufficient to provide a representative indication the material sampled. |
|
| Quality of assay data and laboratory tests |
The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. |
All analyses at Bureau Veritas Laboratories in Perth. Iron- ore suite for all major-element oxides and selected minor element oxides were determined by XRF on fused disks. |
| 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. |
No hand-held geophysical tools or hand-held analytical tools were used for the reported results. |
|
| Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established. |
Laboratory QAQC involves the use of internal lab standards using certified reference material, blanks, splits and replicates as part of their in-house procedures. Results highlight that sample assay values are accurate and that contamination has been contained. |
|
| Verification of sampling and assaying |
The verification of significant intersections by either independent or alternative company personnel. |
No independent of alternative company has been used to verify the intersections. |
| The use of twinned holes. | The drill intercepts reported are from an exploratory drill programme. |
|
| Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. |
Assay data is received electronically and uploaded into an access database. All hand-held GPS locations are checked against the field logs. |
|
| Discuss any adjustment to assay data. | No adjustment or calibrations were made to any assay data presented. |
|
| 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 Resource estimation. |
Drill hole locations are derived from a hand held Garmin 72h GPS units, with an average accuracy of ±3m. |
| Specification of the grid system used. | The grid system is MGA GDA94, zone 50, all easting's and northings are in MGA co-ordinates |
|
| Quality and adequacy of topographic control. |
SRTM90 is used to provide topographic control and is regarded as being adequate for early stage exploration and thelocationofdrill-sites. |
|
| Data spacing and distribution |
Data spacing for reporting of Exploration Results. |
The early-stage drilling is located on sites spaced approximately on a 100m grid over an area of outcroppingmappedmineralization. |
| Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. |
The Mineral Resource statement that is summarised in this report was fully described and attributed in an announcement to the ASX on 3rdFebruary 2015. |
|
| Whether sample compositing has been applied. |
Sample results represent 1m interval reverse circulation drill-chips and samples have not been composited. |
==> picture [92 x 35] intentionally omitted <==
16
| 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, |
Mineralization is contained within a sub-horizontal sheets and the vertical drill-holes and associated sampling collects representative material through the mineralized zone. |
|---|---|---|
| considering the deposit type. | ||
| 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 drill orientation was selected to minimise any sampling bias. |
|
| Sample security | The measures taken to ensure sample security. |
Samples are collected labelled and packed into bulka bags by Coziron Geologists. RGR Transport collected the sealed bulka bags from site and delivered them directly to Bureau Veritas Laboratories in Perth. |
| Audits or reviews | The results of any audits or reviews of sampling techniques and data. |
No audits or reviews of the sampling techniques and data have been obtained. |
| Section 2 Reporting of Exploration Results | ||
| Criteria | JORC Code explanation | Commentary |
| Mineral tenement 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 interests, historical sites, wilderness or national park and environmental settings. |
All exploration licenses and prospecting licenses owned 85% by Zanthus Resources Ltd and 15% by ZanF Pty Ltd. The tenements are covered by the Kuruma Marthudunera Native Title Claim and relevant heritage agreements are in place. |
| 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 tenements are in good standing and no known impediments exist. |
|
| Exploration done by other parties |
Acknowledgment and appraisal of exploration by other parties. |
In 1990-1991, Aberfoyle Resources held tenements covering the Ashburton Trough which partially overlapped Yarraloola. They collected 26 rock-chip and 73 stream sediment samples for gold and base-metal exploration but encountered no significant results and surrendered the ground. |
| In 1991-1992, Poseidon Exploration Ltd held exploration tenements covering the Ashburton Trough which partially overlapped Yarraloola for base-metals, gold and iron-ore. They collected 54 rock-chips, 236 soil samples, 492 stream sediment samples and completed 159 RAB holes for 2410m but encountered no significant mineralisation and surrendered the tenements. |
||
| In 1997-1998, Sipa Resources NL held tenements over the Ashburton Trough that partially covered Yarraloola for gold and base-metals. A field trip after the interpretation of LANDSAT and air-photos collected six rock-chip samples which failed to detect mineralisation and the tenementswere surrendered. |
||
| In 2005-2009, Red Hill Iron Ltd held a tenement 15km northwest of Pannawonica which partially overlapped Yarraloola for gold and base-metal prospectivity. Following and aeromagnetic survey and air-photo interpretation, 16 rock-chips and 207 soil samples were collected but no targets were generated and the ground was surrendered. |
||
| Geology | Deposit type, geological setting and style of mineralisation. |
The eastern section of the tenements covers Archaean- age chemical and clastic sediments overlying basalts in the Hamersley Basin. The western part of the tenements covers deformed Palaeoproterozoic mostly clastic sediments of the Ashburton Trough which are overlain by more recent undeformed detritus associated with the Carnarvon Basin. Sediments of the Hamersley and Carnarvon Basins are known to host economic deposits of iron-ore. |

| 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: |
|
|---|---|---|
o easting and northing of the drill hole collar |
Easting and Northing is reported as GDA Zone50 in Table 3. |
|
o elevation or RL (Reduced Level –elevation above sea level in metres) of the drill hole collar |
The area has only minor relief and a nominal RL of 140m above sea level from the SRTM90 is used for results in this report. A differential GPS survey is planned to providefuture surface control |
|
o dip and azimuth of the hole |
Dipand azimuth is reported in Table 3. | |
o down hole length and interception depth |
Down hole lengths and intercept depths are reported in Table4. |
|
o hole length. |
Hole lengths are reported in Table 3. | |
| Data aggregation methods |
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. |
Intercept values are numerical averages of the 1m sample results reporting Fe>55% with intercepts greater than 5m including a maximum of 2m of samples with Fe<55%. No cutting of high grades has been used. |
| 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. |
All samples intervals used to calculate the intercepts are of equal length. |
|
| The assumptions used for any reporting of metal equivalent values should be clearly stated. |
No metal equivalents are presented | |
| Relationship between mineralisation widths and intercept lengths |
If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. |
The vertical drill-holes are designed to intercept the true widths of the essentially horizontal sheets of pisolitic iron- stone mineralization. |
| If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length, true width not known’). |
The down-hole widths are regarded as true widths of the mineralization. |
|
| Ait d ti ith | Maps of the dill-hole locations are included in the report. Further assay and survey results are required to generate cross-sectional and wire frame models on the distribution of the mineralization. These results will be reported when they become available. |
|
| pproprae maps an secons (w l d bli f i hld b |
||
| scaes) an tauatons o ntercepts sou e 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. |
||
| Diagrams | 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. |
Refer to the maps and cross-sections in body of text which provide a graphical summary of the locations and relationships between the data which is summarised in the tables. |
| Balanced reporting |
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. |
Intervals of samples with Fe>50% and the trace elements appropriate to the description of pisolitic iron- stone are reported. |

DGPS surveying over the mineralized area, quantitative mineralogical studies, infill and extensional drilling is being planned. |
|---|---|---|
| Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. |
Areas of outcropping mineralization have been identified on the map in the body of the text highlight the high prospectivity areas for future work. |
