Cardinal Infill Drilling Results Returned

TORONTO, Feb. 22, 2018 (GLOBE NEWSWIRE) -- Cardinal Resources Limited (CDV.TO)(CDV.TO) (“Cardinal” or “the Company”) is pleased to advise that it has now received the final tranche of assay results from its current phase of infill resource drilling at the Namdini Gold Project in Ghana.  These encouraging results follow on from the previously announced drilling results (refer to ASX/TSX announcement of 22 January 2018), and will now form the basis for an update to the Mineral Resource estimate which is expected to be delivered at the end of the March quarter.

Cardinal’s Chief Executive Officer / Managing Director, Archie Koimtsidis said:

“These are the final tranche of drill results from the infill drilling programme which was specifically designed with the objective of increasing the confidence level by targeting our 3.1Moz of Inferred Resources into the Indicated Mineral Resource category which currently contains 4.3Moz at a 0.5 g/t gold cut-off grade. The Measured and Indicated Mineral Resources will drive our Pit Design and Mining Schedule for the Pre-Feasibility Study that is well underway, and expected to be completed by mid-2018.

“While we are continuing to work towards upgrading our current Mineral Resource base at Namdini by Q1 2018, we also have drill rigs actively testing our highly prospective regional exploration licences for new discoveries, and we look forward to providing information from these first pass drill programmes”.

DISCUSSION OF RESULTS

All drilling results from the current phase of infill drilling have been returned from the comprehensive campaign designed to increase the confidence in the current Namdini Mineral Resource and enable the establishment of a maiden Ore Reserve. The current phase of drilling specifically focused on Mineral Resource conversion by infilling the existing drill pattern to within a nominal 50m x 50m spacing targeting a vertical depth of approximately 400m below surface.  In total, the Company has now completed 96,228m of drilling comprised of 62,935 HQ diamond drill metres and 33,293 5.5’ RC drill metres for the Namdini Mineral Resource. The results strongly support the continuity of mineralization and increase the confidence in the current Mineral Resource.

The Namdini Project currently has an estimated Indicated Mineral Resource of 4.3 Moz of gold and an Inferred Mineral Resource of 3.1 Moz of gold (refer to ASX/TSX announcement on 18 September 2017 for details) at 0.5 g/t cut-off grade. The infill drilling is expected to upgrade a significant portion of the current Inferred Mineral Resource into a higher category thereby increasing the current Indicated Mineral Resource base. Optimisation studies will commence after the Mineral Resource update due Q1 2018, which will then underpin the Company’s maiden Ore Reserve. The Ore Reserve will then form the basis of the Pre-Feasibility and Definitive Feasibility Studies that the Company is progressing for the Namdini Project.

APPENDIX 1
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.
Nature and quality of sampling is carried out under QAQC procedures as per industry standards.
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. Sample representivity is ensured for:
RC samples by collecting 1m samples from a cyclone, passing them through a 3-tier riffle splitter, and taking duplicate samples every 22nd sample.
HQ core through sampling the various lithological units at 1m intervals. The original system used was to sample each unit separately, but after statistical analyses of the results found there was no material grade variation between the units, the half core was sampled at 1m intervals throughout the drill hole. Recent HQ core sampling has been conducted by half core.

 
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 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 sampling hammer of nominal 127 to 140mm holes.
All holes are inclined at varying angles for optimal zone intersection.
All drill collars are surveyed using Trimble R8 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. Method of recording chip and core sample recoveries was to enter the relevant data on a hand-held Motion F5te Tablet PC using a set of standard templates supplied by Maxwell Geoservices, Perth (Maxwell).
Reverse circulation sampling is good.  Chips are logged and 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.
For RC drilling, average recoveries are in the order of 76% and considered acceptable.
Core recovered from each drill run is measured and compared with the drill run length drilled to calculate an estimated percentage core recovery.
For core drilling overall recoveries are excellent, weighted average recovery greater than 98%.

 
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.  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 majority 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 relationship is seen to exist between sample recovery and grade, and no sample bias due to preferential loss/gain of any fine/coarse material due to the acceptable sample recoveries obtained by both 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 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 Mineral Resource estimation.
Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) photography. Logging is both qualitative and quantitative depending on the field being logged.
Both RC chips in trays and HQ core are photographed both in dry and wet form.
The total length and percentage of the relevant intersections logged. All holes are logged in full and to the total length of each drill hole.
100% of each relevant intersection is logged in detail.
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 test-work has shown them to be as equally representative as half core.
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. 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 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. 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:
  • Contamination index of 95% (that is at least 95% of blanks pass; failures can only be attributed to probable minor laboratory contamination.
  • Crushed Size index of P95-2mm (1:50 sample screened).
  • Grind Size index of P85-75µm (1:50 sample screened).
  • Check Samples returning at worse 20% precision at 90th percentile and bias of 5% or better.
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. Quality control procedures adopted for all sub-sampling stages to maximize representivity of samples is to insert commercial certified reference material (CRM) for standards and in-house blanks every 22 samples.
SGS Laboratory assays duplicate samples of each sample batch (20%) so that representivity of the samples can be checked
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. Measures taken to ensure that the RC sampling is representative of the in-situ material collected are to take field duplicate samples every 22nd sample.
Approximately 3kg samples from the splitter are retained from each sample and stored on the company’s premises for possible re‐assay.
Measures taken to ensure that the core sampling is representative is to sample half core at 1m intervals irrespective of lithologies due to the similarities in grade of the main lithologies.
Results of field duplicates, standards and blanks are all plotted graphically to ensure that the results of each assay batch are acceptable.
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 AAS 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 quality of the Fire Assaying and laboratory procedures are considered to be entirely appropriate for this deposit type.
The analytical method is considered appropriate for this mineralization style and is of industry standards.
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 1:20. Duplicates are taken at the riffle splitter at a ratio of 1:22 samples. No duplicate samples are taken from core samples.
Pulp rejects (Check Assays) are submitted to a secondary laboratory for checks on accuracy and precision of the primary laboratory.
Coarse rejects (Check Samples) 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 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 Trimble 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 survey is completed by using Reflex Ez-Shot survey instrument at regular intervals.
Gyroscopic downhole survey was completed on some selected drillholes for the recent drilling using Reflex Ez-Gyro (North Seeking) instrument as part of the quality checks on the downhole surveys.
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 establish mineralization continuity and 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 the geological and grade continuity appropriate for reporting Mineral Resource and Ore Reserve and classifications applied.
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 mineralization as practicable.  This achieves unbiased sampling of possible structures as drilling is orientated normal to the dip and foliation of the deposit. Structural measurements confirm that the foliation of the entire deposit dips -60⁰W so that the sampling achieves unbiased sampling of the lithologies
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 paper work corresponds. The samples are then transported to the SGS Tarkwa (Ghana) or SGS 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 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 Mining Licence covering Cardinal’s Namdini Project over an area of approximately 19.54 sq. Km is located in the North-East region of Ghana.
The previous holder of the Mining Licence, Savannah Mining Ghana Limited (Savanah) completed an initial Environmental Impact Statement (EIS) and lodged the EIS with the Environmental Protection Agency of Ghana.
Cardinal and Savannah have both signed the necessary documents to assign the Namdini Mining Licence to Cardinal Namdini Mining Limited (Cardinal Namdini), a wholly owned subsidiary of Cardinal Resources, for US$1.00 as per the Savannah agreement.  After the completion of the upcoming Preliminary Economic Assessment, Cardinal Namdini will submit to the Minerals Commission an updated EIS and an application for an Operating Permit, bringing all permitting for the Namdini Project on track for development.
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. Aside from Cardinal there has been no recent systematic exploration undertaken on the Namdini Project.
Geology

 
Deposit type, geological setting and style of mineralisation The deposit type comprises gold mineralization within sheared and highly altered rocks containing sulphides; mainly pyrite with minor arsenopyrite.
The geological setting is a Paleoproterozoic Greenstone Belt comprising Birimian metavolcanics, volcaniclastics and metasediments located in close proximity to a major 30 km ~N-S regional shear zone with splays.
The style of mineralization is hydrothermal alteration containing disseminated gold-bearing sulphides.
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:
  • Easting and northing of the drill hole collar
  • Elevation or RL (Reduced Level – elevation above sea level in meters) of the drill hole collar
  • Dip and azimuth of the hole
  • Down hole length and interception depth
  • Hole length
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 mineralization 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 mineralization 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 mineralization is unknown; only downhole length is reported (no true width of mineralization 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 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 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 and long 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.
The immediate aim is to update the existing Mineral Resource to incorporate the new infill results.

 

Further definition drilling is also planned for the Namdini Mineral Resource.
