ABOUT CARDINAL
Cardinal Resources Limited (ASX:CDV) (TSX:CDV) is an African gold-focused exploration and development Company which holds interests in tenements within Ghana, West Africa.
The Company’s Namdini Project has a declared gold Mineral Resource of 23.86Mt @ 1.21 g/t for 931,000 oz Indicated and 100.15Mt @ 1.13 g/t for 3.63 Moz Inferred (Refer to Cardinal “Technical Report on Namdini” dated 5 April 2017). The Company is focused on the development of the Namdini Project through a resource expansion drilling programme, pre-feasibility studies, detailed metallurgical test work and process flowsheet studies. Exploration activity is also underway at the Company’s Bolgatanga (Northern Ghana) and Subranum (Southern Ghana) Projects.
Cardinal technical staff maintain a set of standard procedures for both diamond drilling and reverse circulation drilling. For diamond drilling (which is completed using HQ core collection), the key aspects are that the holes are electronically surveyed every 30 metres down hole, all core runs are routinely oriented using a Reflex digital orientation instrument, core recovery is measured and geotechnical logging is completed as the core is recovered at the rig site. Back at the Bolgatanga office the core is photographed wet and dry and after logging onto digital data recorders, the core is cut such that a half HQ core is retained for reference. The same sector of core, relative to the core orientation mark is routinely sampled for assaying.
For RC drilling, samples are collected on a one metre interval using a multi‐‐‐tier riffle splitter, duplicate field samples are routinely collected (one in 20), the cyclone is thoroughly cleaned on each rod change and the splitter is cleaned after each metre sample. The sample bag weights for each metre interval are routinely weighed, as are the split samples for submission to the assay laboratory and approximately 2.5 to 3 kilogram chip samples are dispatched to the laboratory. Amongst the samples, a suite of internationally accredited and certified reference material along with blanks are included in the sample submission sequence. The standards cover the gold grade range expected at Namdini. The individual sample bags for both core and drill chips are sealed at the Bolgatanga site office and are grouped into tens for placement in a large plastic bag, which is, in turn, sealed. The assay laboratory provides sample transport from Bolgatanga such that the chain of custody passes from Cardinal to the assay laboratory at the Bolgatanga sample logging facility.
Once sample bags and pulps are returned from the assay laboratory to Cardinal’s Bolgatanga facility, a representative suite of pulps, covering the entire range of both sample batches and gold grades are chosen for ‘referee’ analysis at an accredited independent laboratory. As with the routine sample submission, a suite of international certified standards and blanks are inserted into the referee assaying pulp sequence.
Cardinal technical staff carry out routine analysis of the quality control data on receipt of assay results from the laboratory in order to determine if the batch of samples has passed industry standard levels for control samples. If the batch ‘fails’, the batch of assays is rejected and a re‐assay request for the batch of samples is made to the laboratory.

SCHEDULE 2: JORC CODE 2012 EDITION – TABLE 1
Section 1 – Sampling Technique and Data
| 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. | Sampling is by a combination of diamond drill and reverse circulation holes. Diamond sampling include both half-core and quarter-core samples of HQ core size and RC samples are collected by a three-tier riffle splitter using downhole sampling hammers with nominal 127 to 140mm holes. |
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. | Sampling is guided by Cardinal Namdini protocols and Quality Control procedures as per industry standard. | |
| 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. |
Diamond drill samples are firstly crushed using a Jaw Crusher and thereafter crushed to -2mm using a RSD Boyd crusher. A less than 1kg split sample is then pulverised via LM2 to a nominal 85% passing -75µm.
Reverse circulation drill samples are only crushed through a RSD Boyd crusher to -2mm and pulverised via LM2 to a nominal 85% passing-75µm. A 200g sub-sample is taken for analysis. A 50g charge weight is fused with litharge based flux, cupelled and the prill dissolved in aqua regia and gold is determined by AAS. |
|
| 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.). | Diamond core drilling is completed with core size of HQ with a standard tube. Triple tube is used in saprolite at the tops of the hole. Core is orientated using digital Reflex ACT II RD orientation tool.
Reverse circulation drilling uses a sampling hammer of nominal 127 to 140mm holes. All drill collars are surveyed using RTK GPS with downhole surveying every 30m. |
| Drill sample recovery | Method of recording and assessing core and chip sample recoveries and results assessed. | Diamond core recovery is logged and captured into the database. Overall recoveries are excellent with a weighted average recovery greater than 98%.
Reverse circulation sampling is good. Chips are logged and weighed and captured to the database. |
| Measures taken to maximise sample recovery and ensure representative nature of the samples. | Measures taken include the use of bigger HQ core size diamond drilling to maximise recovery, having a geologist onsite to examine core and core metres marked and orientated to check against the driller’s blocks and ensuring that all core loss is taken into account.
At the reverse circulation rig, sampling systems are routinely cleaned to minimise the opportunity for contamination and drilling methods are focused on sample quality. Most of the reverse circulation rigs have auxiliary compressors and boosters to help maintain dry samples. Where wet samples are encountered, the reverse circulation drilling is discontinued and is progressed with diamond core drilling. |
|
| 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 known sample recovery issues have impacted on potential 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 studies and metallurgical studies. | All drill holes are fully logged. The lithology, alteration and geotechnical characteristics of core are logged directly to a digital format on a Field Toughbook laptop logging system following procedures and using Cardinal geologic codes. Data is imported into Cardinal’s central database after validation in LogChief™.
All geological logging is to a level of detail to support appropriate future Mineral Resource estimations. |
| Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) photography. | Logging is both qualitative and quantitative depending on field being logged.
All core is photographed. |
|
| The total length and percentage of the relevant intersections logged. | All holes are fully logged. | |
| Sub-sampling techniques and sample preparation | If core, whether cut or sawn and whether quarter, half or all core taken. | Core orientation is completed for all diamond holes and all are marked prior to sampling. Longitudinally cut half core samples are produced using a Core Saw. Samples are weighed and recorded.
Some quarter core samples have been used and statistical testwork has shown them to be representative. |
| If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry. | RC samples are split using a three-tier riffle splitter. The majority of RC samples are dry. On occasions when wet samples are encountered, they are dried prior to splitting with a riffle splitter. | |
| For all sample types, the nature, quality and appropriateness of the sample preparation technique. | Drill core samples are sorted, dried at 105°C for 4 hours and weighed. Samples are firstly Jaw Crushed and a second stage crushing is through a RSD Jaques crusher to a nominal -2mm and then split to <1.0kg. The reject sample is retained in the original bag and stored. The split is pulverised in a LM2 to a nominal 85% passing 75%µm and approximately 200g sub-sample of the pulverised material is used for assay.
Chip samples are sorted and dried in an oven for 8 hours and weighed. They are then crushed to -2mm using a RSD Boyd crusher and a <1.0kg split is taken. The reject sample is retained in the original bag and stored. The split is pulverised in a LM2 to a nominal 85% passing 75µm and a 200g sub-sample is used for analysis. All preparation equipment is flushed with barren material prior to commencement of the job. |
|
| Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. | 1:20 sample is screened to confirm percentage passing 2mm (crushed) and 75µm (pulverised).
Crusher and pulveriser are flushed with barren material at the start of every batch. |
|
| 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. | Sampling is carried out in accordance with Cardinal protocols as per industry best practice.
Field duplicates have been taken and analysis of results have shown the sampling to be representative. |
|
| Whether sample sizes are appropriate to the grain size of the material being sampled. | The sample sizes are considered appropriate for the mineralisation type. | |
| 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. | Samples are analysed for Au by lead collection fire assay of a 50g charge with ASS finish; the assay charge is fused with the litharge based flux, cupelled and prill dissolved in aqua regia and gold determined by flame AAS.
The analytical method is considered appropriate for this mineralisation style. |
| 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 are used. | |
| 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. | Sample preparation checks for pulp fineness are carried out by the laboratory as part of their internal procedures to ensure the grind size of 85% passing 75µm is being attained. Laboratory QAQC involves the use of internal lab standards using certified reference material and blanks.
Cardinal’s QAQC protocol is considered industry standard with standard reference material (SRM) submitted on a regular basis with routine samples. The SRMs having a range of values and blanks are inserted in the ratio of 1:22. Duplicates are taken at the riffle splitter with a ratio of 1:20 samples. No duplicate samples are taken from core samples. |
|
| Verification of sampling and assaying | The verification of significant intersections by either independent or alternative company personnel. | Significant intersections have been verified by alternative company personnel. |
| The use of twinned holes. | None of the drill holes in this report are twinned. | |
| Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. | Primary data are captured on field tough book laptops using LogChief™ Software. The software has validation routines and data is then imported onto a secure central database. | |
| Discuss any adjustment to assay data. | The primary data is always kept and is never replaced by adjusted or interpreted data. | |
| 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. | Planned drill hole collar coordinates are surveyed using handheld Garmin GPSmap 62s GPS within ±3m accuracy.
All drill collars are accurately surveyed using a Tremble R8 RTK GPS system within ±10mm of accuracy (X, Y, Z). Coordinates are based on 12 control stations established on the Namdini site by Sahara Mining Services. Downhole surveys are completed by using a Reflex Ez-Shot survey instrument at regular intervals. |
| Specification of the grid system used. | Coordinate and azimuth are reported in UTM WGS84 Zone 30 North. | |
| Quality and adequacy of topographic control. | Topographic control was established from aerial photography using a series of 12 surveyed control points. A 1m ground resolution DTM was produced by Sahara Mining Services from the survey completed in 24 flights using the DJI Inspire 1 UAV at an altitude of 100m with an overlap of 70%. | |
| Data spacing and distribution | Data spacing for reporting of Exploration Results. | Drill spacing is at 50m x 100m line spacing with infill to 50m x 50m and 10m x 15m in areas to upgrade the Mineral Resource. |
| 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. | Drill data spacing and distribution are sufficient to establish geological and grade continuity. This latest drilling has not been included in the Mineral Resources. | |
| Orientation of data in relation to geological structure | Whether sample compositing has been applied. | No sample compositing has been applied. |
| Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. | The majority of the drill holes are orientated to achieve intersection angles as close to perpendicular to the mineralisation as practicable. | |
| 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 significant orientation based sampling bias is known at this time. | |
| Sample security | The measures taken to ensure sample security. | An independent Ghanaian security contractor is used to ensure sample security.
The drilling contractor is accountable for drill core and RC chips production at the drill site. Final delivery from the drill site to the laydown within the core yard is managed by Cardinal. The core yard technicians, field technicians and Geologists ensure the core and chips are logged, prepared and stored under security until collected by SGS for delivery to the laboratories. At the time of sample collection, a sign-off process between Cardinal and the SGS delivery truck driver ensures the samples and paperwork corresponds. The samples are then transported to the SGS Tarkwa (Ghana) or Ouagadougou (Burkina Faso) laboratory where they are receipted against the dispatch documents. The assay laboratories are responsible for the samples from the time of collection from Namdini Project site until final results are returned and checked by Cardinal Geologists. Sample pulps and coarse rejects are retained by the laboratories and are shipped back to Namdini after final results are returned where they are stored under security. |
| Audits or reviews | The results of any audits or reviews of sampling techniques and data. | No external audits or reviews of the sampling techniques and data have been completed. |

A summary of all information material to the understanding of these exploration results is contained within this announcement. |
| 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 why this is the case. | There has been no exclusion of information. | |
| 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. | Significant intersections are calculated using a 3m minimum width, 3m contiguous internal waste and 0.5g/t Au minimum grade.
Gold grades used for calculating significant intersections are uncut and the results are length weighted. |
| Where aggregated 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. | Aggregated intercepts incorporating short lengths of high grade results within the lithological units are calculated to include no more than intervals of 3m below grades of <0.5 g/t Au when assay results are reported. | |
| The assumptions used for any reporting of metal equivalent values should be clearly stated. | No metal equivalents are used in the intersection calculation. | |
| Relationship between mineralisation widths and intercept lengths | These relationships are particularly important in the reporting of exploration results. | The relationship between mineralisation widths and intercept length is not yet known. |
| If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. | The geometry of the mineralisation with respect to the drill hole angle 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’). | The geometry of the mineralisation is unknown; only downhole length is reported (no true width of mineralisation is reported). | |
| 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. | Appropriate maps and cross-sections with scale are included within the body of the accompanying document. |
| Balanced Reporting | Where comprehensive reporting of all Exploration Results is not practical, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. | The accompanying document is considered to represent a balanced report. |
| Other substantive exploration data | Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observation; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical & rock characteristics; potential deleterious or contaminating substances. | Other exploration data collected is not considered material to this document at this stage.
Further data collection will be reviewed and reported when considered material. |
| 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. |
Exploration drilling will continue to target projected lateral and depth extensions of the mineralisation and infill drilling to increase the confidence in the Mineral Resource. Results from the drilling will be included in the next Mineral Resource update. |
