TORONTO, Aug. 29, 2018 (GLOBE NEWSWIRE) -- Cardinal Resources Limited (ASX/TSX: CDV) (“Cardinal” or “the Company”) is pleased to announce further shallow gold intersections to the exploration drill results previously announced on 16 July 2018 from its new Ndongo East discovery on the Ndongo License. The Ndongo East prospect is located approximately 20km north of the Company’s Namdini Gold Project which has a 6.5Moz Indicated Mineral Resource.
Highlights
- Significant gold intersections include:
• 2m @ 27.0 g/t Au from 10m in NDRC247
• 6m @ 12.6 g/t Au from 2m in NDRC275
• 7m @ 2.2 g/t Au from 55m in NDRC276 - Shallow RC drilling has encountered multiple intercepts of near-surface gold mineralisation over a strike length of approximately 1.2km
- Prospectivity of Ndongo East enhanced by proximity to historic Nangodi Gold Mine on regional Nangodi Shear Zone
Cardinal’s Chief Executive Officer / Managing Director, Archie Koimtsidis stated:
“These latest shallow, significant gold intersections have provided a possible threefold extension to the original 400m strike length discovery zone to 1.2km in length.
“The Ndongo East prospect lies within a larger target area of approximately 7km in strike length which has yet to be RC drill tested.
“We are increasingly encouraged at how Ndongo East is evolving with the potential to add high-grade gold ounces to our 6.5Moz Namdini Gold Project located only 20km to the south and we expect the recommencement of the drilling as soon as possible after the wet season ends during October-November 2018”.

Ndongo Prospecting License
The Ndongo Prospecting License covers an area of 295km2, having been expanded by the purchase of two exploration license areas from Kinross Gold in August 2017 (Figure 1).
The license area is considered highly prospective for the discovery of economic gold mineralisation associated with the prolific Nangodi Shear Zone, a splay fault off the main regional-scale Bole-Bolgatanga Shear. The Nangodi Shear Zone is spatially related to no fewer than four significant gold discoveries, including the Company’s Namdini Gold Project with 6.5Moz Indicated Mineral Resource, the Shaanxi Gold Mine, the historic Nangodi Gold Mine and the Youga Gold Mine in Burkina Faso, adjacent to the Ghana border. In addition, there are numerous historic shallow artisanal workings along many parts of this shear zone including the Dusi, Zug and McGuiness Prospects which all fall within Cardinal’s license area (Figure 2).
Ndongo East Prospect
The Ndongo East Prospect is located within NE-SW trending Birimian metavolcanics and metasediments.
Previously announced drilling intersected higher-grade gold mineralised structures concentrated in the northern portion of the shear zone over a 400m strike length on coincident gold-in-soil and geophysical targets (refer to Cardinal’s ASX/TSX announcement 16 July 2018 “Cardinal Makes New Gold Discovery at Ndongo”).
Cardinal’s most recent RC drilling along fence lines to test mineralisation further to the southwest along strike and at depth has proven encouraging as further significant intercepts within the mineralised structures suggest mineralisation continues. The furthest drill fence to the southwest intercepted a narrow zone of mineralisation of 2m grading 27.0 g/t Au from 10m downhole in NDRC247 which indicates a strike potential of up to 1.2km of mineralised structures (Figure 3 and 5). Further infill drilling is planned to test this extended zone.
Drill Section E - E¹ is typical of the intersections encountered during the RC drilling, with gold mineralisation developed at, or near, the diorite-granodiorite contacts where competency differences create brittle fracturing which allows the ingress and precipitation of mineralising fluids (Figure 4). The mineralised horizons contain variable chlorite-silica-carbonate-sericite alteration with sulphides (mainly pyrite with very minor arsenopyrite).
The mineralised system is open along a northwest-southeast strike and at depth with multiple mineralised intersections (Figure 5 and Table 2).
We expect to recommence drilling after the wet season during October-November 2018 in order to test the strike and depth extents of the mineralised system.

| 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. | Reverse Circulation (RC) drill samples are collected by using downhole sampling hammers with nominal 127 to 140mm diameters. Samples are collected through a cyclone and immediately weighed to determine recoveries; the entire sample is then split by a three-tier riffle splitter. Two samples (~2.5-3.0 kg) are collected, one for the lab, the other a duplicate stored at the Bolgatanga sample shed. |
| 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 Resources protocols and Quality Control procedures as per industry standard. To ensure representative sampling, 1m RC samples are collected from a cyclone, passing them through a three-tier riffle splitter, and taking duplicate samples every 20th sample. | |
| 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. | The determination of mineralisation is based on observed alterations and lithological differences. RC samples are crushed through a RSD Boyd crusher to -2mm, then a <1kg split sample is pulverised via LM2 Ring Pulveriser to a nominal 85% passing -75µm. A 200 g sub-sample is taken from the pulverised material for analysis. A 50 g charge weight is fused with litharge-based flux, cupelled and the prill dissolved in aqua regia. The gold tenor is then 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.). | Reverse circulation drilling uses sampling hammer of nominal 127 to 140mm diameter. Drill holes are inclined at -45⁰ to -60⁰ angles for optimal zone intersection. All RC drill collars are surveyed using Trimble R8 RTK GPS with downhole surveying every 30m using Reflex digital surveying instruments. |
| Drill sample recovery | Method of recording and assessing core and chip sample recoveries and results assessed. | The method of recording RC chip sample data is to enter the relevant data onto a hand-held Motion F5te Tablet PC using a set of standard templates supplied by Maxwell Geoservices, Perth (Maxwell). Reverse circulation sampling is good. RC chips are logged, weighed and captured to the database. RC sample recoveries are assessed by weighing 1m samples from the cyclone on a scale in the field and comparing with the theoretical volume contained in a 1m x 140mm diameter hole to calculate an estimated percentage sample recovery. |
| Measures taken to maximise sample recovery and ensure representative nature of the samples. | At the reverse circulation rig, sampling systems are routinely cleaned to minimise the opportunity for contamination and drilling methods are focused on sample quality. The measures taken to maximize RC sample recovery are through a cyclone and a 3-tier riffle splitter. Each 1m sample is passed twice through the splitter before sampling to ensure maximum homogenisation of each sample and to collect an unbiased representative sample to be assayed. 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. | |
| 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 relationship is seen to exist between RC sample recovery and grade, and no sample bias has occurred due to preferential loss/gain of any fine/coarse material due to the acceptable sample recoveries obtained by the drilling methods employed. | |
| 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 RC drill samples are fully logged according to observed lithology and alteration 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 RC chip geological logging is to a level of detail to support Mineral Resource estimation when required. |
| Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) photography. | Logging is both quantitative and qualitative. RC chips in trays are photographed both in dry and wet form. | |
| The total length and percentage of the relevant intersections logged. | All RC holes are logged in full and to the total length of each drill hole. | |
| Sub- sampling techniques and sample preparation | If core, whether cut or sawn and whether quarter, half or all core taken. | No core was drilled. |
| 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 that 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. | RC drill samples are sorted and dried in an oven for eight 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. | Cardinal Resources has protocols that cover the sample preparation at the laboratories and the collection and assessment of data to ensure that accurate steps are used in producing representative samples for the analytical process. Key performance indices include:
| |
| 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. | RC sampling is carried out in accordance with Cardinal protocols as per industry best practice. Quality control procedures adopted for all sub-sampling stages to maximize representativeness of samples is to insert commercial certified reference material (CRM) for standards and blanks every 20 samples. The Laboratory assays duplicate samples of each sample batch (20%) so that representation of the samples can be checked. Field duplicates have been taken and analysis of results have shown the sampling to be representative. The measures described above are not applicable for Rock Chip sampling. | |
| Whether sample sizes are appropriate to the grain size of the material being sampled. | Measures taken to ensure that the RC sampling is representative of the in-situ material collected are to take field duplicate samples every 20th sample. Approximately 3kg samples from the splitter are retained from each sample and stored at the company’s secured premises for possible re‐assay. Results of field duplicates, standards and blanks are all evaluated to ensure that the results of each assay batch are acceptable for the RC drill samples. | |
| 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 samples are analysed for gold by lead collection fire assay of a 50 g charge with AAS finish; the assay charge is fused with the litharge-based flux, cupelled and prill dissolved in aqua regia and gold tenor determined by flame AAS. The analytical method is considered appropriate for the mineralisation style and is of industry standards. The quality of the Fire Assaying and laboratory procedures are considered to be entirely appropriate for the rock samples submitted. |
| 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. Laboratories’ QAQC involves the use of internal lab standards using certified reference material (CRM) and blanks. Cardinal’s QAQC protocol is considered industry standard with CRMs submitted on a regular basis with routine samples. The CRMs having a range of values and blanks are inserted in the ratio of 1:20. Duplicates are taken at the riffle splitter every 20th sample. No duplicate samples are taken from core samples. Pulps are submitted to a secondary laboratory for checks on accuracy and precision of the primary laboratory. Coarse rejects are submitted back to the primary laboratory to assess the adequacy of the sub-sampling process. | |
| Verification of sampling and assaying | The verification of significant intersections by either independent or alternative company personnel. | Significant intersections from RC samples 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. | RC drill hole collar coordinates are surveyed using handheld Garmin GPSmap 62s GPS within ±3m accuracy. All drill collars are accurately surveyed using Trimble R8 RTK GPS system within ±10mm of accuracy (X, Y, Z). Coordinates are based on three control stations established at Namdini by Sahara Mining Services. Downhole survey on RC drill holes is completed by using Reflex Ez-Shot survey instrument at regular 30 m 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 at Ndongo was supplied by Southern Geoscience Consultants (Perth) using satellite imagery. | |
| Data spacing and distribution | Data spacing for reporting of Exploration Results. | The RC drilling was carried out on variably spaced fence lines (30m to 775m apart) with hole spacing of 50m along lines testing mineralisation to a vertical depth of approximately 200m and covering a strike length of 1.25km |
| 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. | Exploration is at the early stage, and as such drill data spacing and distribution are insufficient to establish geological and grade continuity that are appropriate for reporting Mineral Resources and Ore Reserves. | |
| 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. | RC drillholes are orientated to achieve intersection angles as close to perpendicular to the mineralisation as practicable based on ground magnetic modelling data. Some sampling bias may occur. Systematic geological mapping and diamond drilling are required to determine the true orientation of dips and structures of the mineralisation. | |
| 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 field technicians and geologists ensure the rock chip samples are logged, prepared and stored under security until collected for delivery to the laboratories. At the time of sample collection, a sign-off process between Cardinal and the laboratory delivery truck driver ensures that samples and paperwork correspond. The samples are then transported to the laboratory where they are receipted against the dispatch documents. The assay laboratories are responsible for the samples from the time of collection from Cardinal 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 Cardinal 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. | Sampling techniques are of industry standards. Data is audited by Maxwell Geoservices (Perth), who have not made any other recommendations. |
Section 2 – Reporting of Exploration Results
(Criteria listed in section 1 will also apply to this section where relevant)
| Criteria | JORC Code Explanation | Commentary |
| Mineral Tenement and Land Status | Type, name/reference number, location and ownership including agreements or material issues with third parties including joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. | The Ndongo Exploration Permit is on PL9/22, PL9/13 and PL9/19 licenses over an area of 295 sq. km located in the North-East region of Ghana. |
| The security of the tenure held at the time of reporting along with any known impediments to obtaining a license to operate in the area. | All tenements are current and in good standing. | |
| Exploration Done by Other Parties | Acknowledgment and appraisal of exploration by other parties. | Exploration in the region has been undertaken by a number of groups including:
|
| Geology | Deposit type, geological setting and style of mineralisation | RC samples were collected within sheared and folded rocks containing sulphides; mainly pyrite with minor arsenopyrite. The geological setting is a Paleoproterozoic Greenstone Belt comprising Birimian metavolcanics, volcaniclastics and metasediments located along portion of the regional Bole-Bolgatanga Shear Zone and a splay off this Shear Zone (the Nangodi Shear Zone). The style of mineralisation is yet to be determined. |
| Drill hole information | A summary of all information material to the understanding of the exploration results including tabulation of the following information for all Material drill holes:
| A summary of drill hole information is provided in this document. |
| 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. | No weighting averaging techniques nor cutting of high grades have yet been undertaken. |
| 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 from RC drilling are 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 angles 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 plane view of drill hole collar locations and appropriate sectional views. | Appropriate locality map is 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 and rock characteristics; potential deleterious or contaminating substances. | Other exploration data collected is not considered material to this document at this stage. The interpretation of the geological observations shown in the cross sections are subject to possible change as new information is gathered. 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. | Geological mapping, surface rock sampling, trenching, geophysical surveys and RC drilling are continuing. Further RC drilling is required along strike and at depth to further delineate this gold mineralised zone and to determine whether more sub-parallel mineralised horizons can be located. |
