Abundant visible gold panned from Southern Gold Zone
o Visible gold now identified in 3 separate locations along a 2200 metre trend
High grade trench sample assays from Southern Gold Zone received
o 3 metres at 11 g/t including one metre at 17.9 g/t gold
Three major mineralised systems containing visible gold at surface now identified
White Cliff Minerals Limited ("White Cliff" or the "Company") is pleased to report that abundant visible gold has been panned from an exceptionally rich mineralised outcrop at the eastern end of the Southern Gold Zone (SGZ). This new outcrop extends the SGZ to at least 2500 metres with visible gold identified at three locations over 2200 metres.
The SGZ is 400 metres south of the inferred Aucu gold resource of 156,000 ounces (1.2Mt at 4.2 g/t) and is easily accessible from existing tracks. The new zone will be targeted in the upcoming drilling program which is planned to significantly increase the current inferred resource.
Managing Director Todd Hibberd commented that, "The Company has now identified three major mineralised systems, each extending over 2500 metres and each containing visible gold at SURFACE in more than one location. The upcoming drill program will enable us to conduct first pass drilling of this new zone while also extending the foot print of the existing high grade deposit".
"We now believe that deposit has the potential to contain several million ounces based on the rock sampling,
trenching and drilling to date."

White Cliff Minerals Limited 3JORC Compliance
The Information in this report that relates to exploration results, mineral resources or ore reserves is based on information compiled by Mr Todd Hibberd, who is a member of the Australasian Institute of Mining and Metallurgy. Mr Hibberd is a full time employee of the Company. Mr Hibberd has sufficient experience which is relevant to the style of mineralisation and type of deposits under consideration and to the activity that he is undertaking to qualify as a Competent Person as defined in the 2012 edition of the `Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (the JORC Code)`. Mr Hibberd consents to the inclusion of this information in the form and context in which it appears in this report.
The following information is provided to comply with the JORC Code (2012) requirements for the reporting of the Exploration Results and Mineral Resources on tenement AP590.
Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
Criteria | JORC Code Explanation | Commentary |
Sampling Techniques | 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 handheld XRF instruments, etc.). These examples should not be taken as limiting the broad meaning of sampling | Trenches were sampled by hand using a rock hammer with samples collected in 1 metre intervals by chipping across the entire 1 metre rock face. Rock chip samples were collected by hand using a rock hammer with multiple pieces of rock collect at one location for each sample. |
Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. | The sample locations are picked up by handheld GPS. Sample rock types were recorded where the rock was identifiable. Sampling was carried out under standard industry protocols and QAQC procedures | |
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 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 (e.g. submarine nodules) may warrant disclosure of detailed information. | Samples ranged between 1 and 3 kg were crushed to 2mm and a 200 gram subsample was extracted and pulverized to produce a 1-2 gram sample for gold analysis by Aqua Regia digest and Atomic Adsorption Spectrophotometry (AAS), and for copper analysis via pressed pellet X-ray florescence (XRF). | |
Drilling Techniques | 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.). | No drilling has been carried out |
Drill sample recovery | Method of recording and assessing core and chip sample recoveries and results assessed | No drilling has been carried out |
Measures taken to maximise sample recovery and ensure representative nature of the samples. | No drilling has been carried out | |
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. | No drilling has been carried out | |
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. | No drilling has been carried out |
Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) Photography | No logging has been carried out. The samples collected are rock chips and trench samples. Sample lithology is qualitative | |
The total length and percentage of the relevant intersections logged. | Refer to text in the main body of the announcement | |
Sub-sampling techniques and sample preparation | If core, whether cut or sawn and whether quarter, half or all core taken. | No drilling has been carried out |
If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry. | Samples were collected directly from the rock. Samples taken were dry. | |
For all sample types, the nature, quality and appropriateness of the sample preparation technique | Samples were collected directly from the trench or surface via rock hammer sampling. Rock samples are inherently variable and do not accurately represent the average grade of the surrounding rock. Rock samples are used as an non-quantitative guide for assessing prospectivity hence are regarded as suitable for this purpose | |
Quality control procedures adopted for all sub- sampling stages to maximise representivity of samples | At this stage of the exploration no sub sampling is undertaken during the collection stage | |
Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second- | The whole sample collected is crushed to 2mm and a 200g sub-sample pulverised. A 1-10 gram sub sample of the pulverised sample is analysed. Field duplicates |
Criteria | JORC Code Explanation | Commentary |
half sampling | are not routinely collected at the rock sampling stage of exploration | |
Whether sample sizes are appropriate to the grain size of the material being sampled | The sample sizes are considered to be appropriate to correctly represent the sought after mineralisation style | |
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. | The analytical techniques used Aqua Regia digest, Atomic adsorption Spectrophotometry for gold analysis and XRF for copper analysis suitable for the reconnaissance style sampling undertaken. |
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. | Copper analysis was carried out by X-Ray Fluorescent Spectrometer Quant'X (Thermo Scientific (Austria- USA)). Analysis is performed at a rhodium tube with 30…50 kV voltage and 0, 13 mm palladium filter. Gold analysis was carried out using a Thermo Scientific Solar S2 AA-Spectrometer with Atom Trap STAT (Slotted Tube Atom Trap), gaseous hydride generation system (VP100 Continuous Flow Vapour System) | |
Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. 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 the in house procedures. | |
Verification of sampling and assaying | The verification of significant intersections by either independent or alternative company personnel. | An executive director has visually verified significant intersections in rock samples from the Chanach project. |
The use of twinned holes | Not Applicable | |
Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols | Primary data was collected using a set of standard Excel templates on paper and re-entered into laptop computers. The information was sent to WCN in-house database manager for validation and compilation into an Access database. | |
Discuss any adjustment to assay data | No adjustments or calibrations were made to any assay data used in this report. | |
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. | Sample locations were recorded using handheld Garmin GPS60s. Elevation values were in AHD RL and values recorded within the database. Expected accuracy is + or - 5 m for easting, northing and 10m for elevation coordinates. No down hole surveying techniques were used due to the sampling methods used. |
Specification of the grid system used. | The grid system is WGS84 UTM (zone 42 north) | |
Quality and adequacy of topographic control. | Topographic surface uses handheld GPS elevation data, which is adequate at the current stage of the project. | |
Data spacing and distribution | Data spacing for reporting of Exploration Results. | The nominal sample spacing is 1 m (northing) by 1 m (easting). |
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 mineralised domains have not yet demonstrated sufficient continuity in both geological and grade continuity to support the definition of Mineral Resource and Reserves, and the classifications applied under the 2012 JORC Code. | |
Whether sample compositing has been applied. | Samples have not been composited | |
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 sampling method is used to provide a surface sample only. |
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 | No orientation based sampling bias has been identified in the data at this point. | |
Sample security | The measures taken to ensure sample security. | Sample security is managed by the Company. Since at this stage these are field analyses, no sample transit security has been necessary. |
Audits of reviews | The results of any audits or reviews of sampling | The Company carries out its own internal data audits. |

techniques and data. | No problems have been detected. |
Section 2 Reporting of Exploration Results
(Criteria listed in the preceding section also apply to this section.)
Criteria | 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. | The mineralisation is located within Exploration License AP590 which is a Joint Venture between White Cliff Minerals Limited (90%) and BW3 Pty Ltd (10%) There are no other material issues |
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 tenement is in good standing and no known impediments exist. | |
Exploration done by other parties | Acknowledgment and appraisal of exploration by other parties. | None |
Geology | Deposit type, geological setting and style of mineralisation. | The geological setting is of Cambrian to Permian aged intrusive porphyry systems, bounded by overlying basaltic, and sedimentary rocks. Mineralisation is mostly situated within granitic porphyry units as broad alteration containing copper sulphides and within narrow quartz veins and faults. |
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: | No drilling has been carried out |
easting and northing of the drill hole collar | ||
elevation or RL (Reduced Level - elevation above sea level in metres) of 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 | ||
Data Aggregation methods | In reporting Exploration Results, weighting 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 length weighting has been applied due to the nature of the sampling technique. No top-cuts have been applied. |
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. | Not applicable for the sampling methods used. | |
The assumptions used for any reporting of metal equivalent values should be clearly stated | No metal equivalent values are used for reporting exploration results. | |
Relationship between mineralisation widths and intercept lengths | These relationships are particularly important in the reporting of Exploration Results: If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. 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'). | The sampling technique used defines a surficial geochemical expression. No information is attainable relating to the geometry of any mineralisation based on these results. |
Diagrams | Appropriate maps and sections (with scales) and tabulations of intercepts should 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` | Refer to figures in the body of text. |
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 | All results within the mineralised zones are reported. |
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 | NIL |
Criteria | Explanation | Commentary |
characteristics; potential deleterious or contaminating substances. | ||
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). Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. | RAB/AC drilling will be used to further define the nature and extent of the geochemical anomalism, and to gain lithological information. |
