2. Basal Achievability Absorption Ambit and Complete Assumptions
The PFS absorption basal aggregate estimates, was completed to an accurateness of 30 % / -20 % for the 9.5 Mtpa advantage and was undertaken based on alone attainable pit mining from the complete March 2018 Mineral Resources. The proposed bulb comprises a primary crushing, milling (SAG ball), re-crush, gravity, flotation, administer regrind and CIL circuit. Three assembly throughputs were adjourned by Cardinal, namely 9.5, 7.0 and 4.5 Mtpa. The 9.5 and 4.5 Mtpa throughput options were factored from the 7.0 Mtpa advantage ( 20 / -15% accuracy) and are appropriately lower in accurateness at 30 / -20%. A accident agency of 5% was added to the 9.5 and 4.5 Mtpa options over and aloft the action contingency.
Metallurgical testwork agitated out to date indicates that gold can be abundantly recovered from Namdini ore appliance accepted flotation, regrind and Carbon In Bleed (CIL) of the abutment concentrate. The testwork is brash adequate to actuate that the Namdini Mineral Adeptness represents a drop with abeyant bread-and-er extraction. Admiration of basal costs was able by Lycopodium for the action bulb and associated infrastructure.
Golder Associates Pty Ltd (“Golder”) provided attainable pit abundance engineering services. The appointment comprised accumulating of ascribe parameters, attainable pit optimisation studies, pit designs and abounding NPV optimised abundance schedules. A alternation of shells from the attainable pit optimisations was called and acclimated to accomplish engineering pit designs that included a Amateur Pit and Activity Of Abundance (LOM) stages for the LOM assembly schedule.
Golder estimated the Ore Assets in accordance with the JORC Cipher (2012). The appellation ‘Ore Reserve’ is alike with the appellation ‘Mineral Reserve’ as acclimated by Canadian Civic Apparatus 43-101 ‘Standards of Acknowledgment for Mineral Projects’ (NI 43-101, 2014) and conforms with CIM (2014). The JORC Cipher (2012) is authentic as an ‘acceptable adopted code’ beneath NI 43-101. The JORC Table 1 is displayed in Appendix 1.
This Ore Assets appraisement is based on the revised Mineral Adeptness archetypal referred to in the columnist absolution by Cardinal Assets Bound to the ASX and TSX, anachronous March 5, 2018 blue-blooded ‘Cardinal Upgrades Adumbrated Mineral Adeptness to 6.5 Moz’ (Cardinal, 2018). Golder provided an appraisement of mining, including haulage, appointment and blast, rehabilitation and administering costs. Lycopodium provided processing aggregate estimates.
The Ore Assets was estimated from the Mineral Adeptness afterwards appliance of the akin of aplomb in the Mineral Adeptness and because complete and accordant modifying factors including mining, processing, infrastructure, environmental, legal, amusing and bartering factors. The Credible Ore Assets appraisement is based on Adumbrated Mineral Resources. No Inferred Mineral Adeptness was included in the Ore Reserve. The Ore Assets represents the economically mineable allotment of the Adumbrated Mineral Resources. There is no Proved Ore Assets aback no Abstinent Mineral Adeptness has yet been defined.
The proposed abundance plan is technically achievable. All abstruse proposals fabricated for the operational actualization absorb the appliance of accepted technology that is broadly utilised in the gold industry. Banking modelling completed as allotment of the PFS actualization that the Action is economically applicative beneath accepted assumptions. Modifying Factors (mining, processing, infrastructure, environmental, legal, amusing and commercial) were brash during the Ore Assets admiration process. The PFS incorporates a cardinal of factors and assumptions as categorical in the sections below.
The banking archetypal was completed as a complete discounted model. A LOM banking appraisement was performed appliance the discounted banknote breeze (DCF) acclimation and capricious complete abatement rates. The banking appraisement was acclimated to actuate the abeyant bread-and-er acknowledgment of the action over the LOM.
The afterward basal agenda (Table 1) is answerable to attainable funding, complete outcomes for the PFS and DFS and favourable timelines for permitting;
3. Gold Aggregate Used
Table 2 beneath describes the gold aggregate assumptions acclimated for the purposes of the PFS.
4. Absorption Team
Cardinal commenced its PFS in October 2017 to added beforehand the Namdini Gold Project. This consisted of an Owner’s Accession and assiduity with ahead called and anew called consultants to abetment with the phased development of the Namdini Gold Project. The consultants and their roles are archival below:
5. College Throughput Advantage Study
During the PFS study, Cardinal evaluated college action throughput options to appraise whether the 6.5 Moz Mineral Adeptness was able to abutment college throughputs. Golder Associates and Intermine Engineering Consultants (Intermine) were alone tasked to accomplish an acclimation of consequence absorption on the aloft throughput options appliance adapted Whittle optimisations and pushbacks (stages). Cardinal provided acclimation of consequence basal and operating costs for the aloft throughput options to Golder and Intermine.

7. Namdini All-around Mineral Resources
Independent mining industry consultant, MPR Geological Consultants Pty Ltd (“MPR”) was commissioned by Cardinal to appraisement the Mineral Assets of the Namdini deposit. The Mineral Adeptness appraisement was arise in accordance with the JORC Cipher (2012) as credible in Appendix 1 – JORC Table 1. The Mineral Adeptness estimate, abbreviated in the afterward table (Table 2), letters the Mineral Assets by chic and complete blazon (weathering) aloft a 0.5 g/t gold complete grade. The allocation categories of Inferred and Adumbrated Mineral Assets beneath the JORC Cipher (2012) are agnate to the CIM categories of the aforementioned name (CIM, 2014).
Table 4 and Table 5 Notes:
The Namdini gold drop is a large, structurally controlled, orogenic gold drop with abounding actualization agnate to deposits begin abroad in backward Proterozoic Birimian terranes of West Africa. The Namdini gold drop has so far been delineated over a bang breadth of 1,150m, up to 300 m avant-garde and 700m abysmal and is anchored aural the Nangodi Greenstone Belt.
In 2016, geological consultants from Orefind Pty Ltd conducted an on-site structural absorption and developed a structural framework with controls on, and geometry of, gold mineralization complete the Namdini deposit.
Orefind assured that the basement types complete the Namdini Action included a steeply west dipping Birimian acclimation of interbedded, foliated, metasedimentary and metavolcanic units which acquire been intruded by a medium-grained granitoid and diorite. The southern allotment of the Action is covered by flat-lying Voltaian Basin clastic sedimentary rocks that acquire been deposited unconformably on the Birimian acclimation and antedate mineralization and the host sequence.
Underneath the weathering profile, the Birimian units board metasedimentary, metavolcanic, granitoid (tonalite) and diorite. The metasedimentary and volcaniclastic lithologies acquire been acutely adapted with a constant pyrite-carbonate-muscovite-chlorite-quartz assemblage. About-face is best accustomed in the volcaniclastic units. Similarly, the tonalite is abundantly adapted and has been overprinted by silica-sericite-carbonate assemblages.
In all basement types, the mineralization is accompanied by arresting broadcast sulphides of pyrite and complete accessory arsenopyrite in both the veins and coffer rocks. In architecture appointment core, the mineralized zones are visually characteristic due to the attendance of millimetre to centimetre avant-garde quartz-carbonate veins that are frequently bankrupt and acquire bare sericite-carbonate selvages. Rare arresting gold occurs in acerb adapted granite and is associated with sub-millimetre avant-garde silica-sericite shears.
8.1 Drilling Techniques
The ascribe dataset acclimated for the Namdini Mineral Adeptness appraisement comprises a complete of 167 HQ architecture aggregate holes and 144 RC appointment holes totalling 82,870 m.
Reverse apportionment conduct (nominally 5¼ inch diameter) was usually 200 m or beneath in depth. All about-face apportionment holes were downhole surveyed at 30 m intervals.
Diamond conduct was HQ in both asperous and alpha rock. All architecture holes were downhole surveyed at 30 m intervals. All HQ aggregate was orientated.
All about-face apportionment samples were calm at the appointment armpit over 1 m intervals and breach appliance a multi-stage riffle splitter.
Diamond aggregate was about sawn in half; with bisected beatific for assaying, and bisected retained in aggregate trays for approaching reference. One accent samples were taken and submitted to an complete chic for assaying. At the laboratory, both aggregate and about-face apportionment samples followed a accepted action of drying, crushing and grinding. The pulverised samples were thoroughly alloyed on a rolling mat (“carpet roll”) and again 200 g of sub-sample was collected. Centralized chic checks adapted at atomic 90% of the lurid accidental 75 microns. A 50 g allegation was produced for consecutive blaze appraisement analysis.
Very adequate accretion of both aggregate and about-face apportionment samples were recorded and brash to be adumbrative of the mineralisation authentic by the drilling.
8.3 Sample Analytic Methods
Cardinal acclimated two laboratories for its sample submissions, SGS Ouagadougou Chic in Burkina Faso and SGS Tarkwa Chic in Ghana. The complete SGS bartering geochemical analytic laboratories are acutely accustomed by the South African Civic Accreditation Arrangement (SANAS) for affair the requirements of the ISO/IEC 17025 accepted for specific registered tests for the Minerals Industry.
As allotment of the Cardinal QAQC, a apartment of internationally accepted and certified advertence complete (standards) and locally sourced blanks were included in the sample acquiescence sequence. The standards awning gold brand ranges accepted at Namdini. Interlaboratory adjudicator analyses were additionally conducted.
Certified advertence complete (blanks and standards) were submitted into the sample beck at a aggregate of 1 in 22 samples. Alike samples of about-face apportionment chips were taken at a aggregate of 1 in 22.
No employee, officer, director, or accessory of Cardinal agitated out any sample alertness on samples from the Namdini Action appraisement programme. Appointment aggregate was transported from the appointment armpit by a Cardinal agent to the defended aggregate backyard adeptness at the Bolgatanga Acreage Appraisement Appointment only.
All samples calm for assaying are retained in a locked, defended accumulator adeptness until they are calm and transported by the SGS chic personnel. Retained appointment aggregate is deeply stored in the aggregate accumulator adeptness and pulps and abject rejects alternate from the laboratories are deeply stored in the appraisement aggregate logging breadth and at a adjoining defended breadth in Bolgatanga, Ghana.
8.4 Geological and structural modelling
Logging, admiration and modelling were undertaken by Cardinal Resources’ abstruse agents appliance Maxwell Geoservices (Perth) “Logchief” software and specialist structural consultants Orefind Pty Ltd, (Davis and Cowan, 2016-2017) constant in a three-dimensional archetypal of key lithologies, structures and weathering zones.
8.5 Estimation Methodology
MPR estimated recoverable assets for Namdini appliance Assorted Indicator Kriging (“MIK”) with block abutment adjustment, a acclimation that has been accustomed to board reliable estimates of recoverable attainable pit assets in gold deposits of assorted geological styles. The Mineral Adeptness was estimated appliance assorted indicator kriging appliance GS3M software developed by FSSI Consultants (Australia).
Estimation was answerable aural a mineralization envelope (wireframe) based on geological logging and brand thresholds. The three-main host lithologies are granite, metavolcanics and diorite. Breadth geological contacts were not acutely authoritative the administering of mineralization, a brand complete of about 0.1 g/t Au was acclimated to assemble Mineral Adeptness boundaries.
The breadth trends north-northeast over 1.3 km and dips about 60o to the west with an boilerplate accumbent amplitude of about 350 m. The Mineral Adeptness can analytic be accepted to board appropriately reliable estimates of abeyant mining outcomes at the affected selectivity, afterwards appliance of added mining concoction or mining accretion factors. Validation of the MIK archetypal was undertaken visually and statistically and brash independently.
Parent block ambit of 12.5 mE by 25 mN by 5 mRL were acclimated for estimation. All sample assays were composited to 2 m above-mentioned to estimation.
The Namdini Mineral Adeptness has been classified into the Adumbrated and Inferred categories, in accordance with the JORC Cipher (2012) and the CIM Standards (CIM, 2014). A ambit of belief were brash in free this allocation including geological and brand continuity, abstracts affection and appointment hole spacing.
The key allocation belief are declared as follows:
Resource archetypal blocks acquire been classified as Adumbrated or Inferred on the abject of chase passes and a wire-frame analogue added carefully accomplished portions of the mineralization. Blocks aural the allocation wire-frame a by all chase passes were classified as Indicated. Blocks alfresco the allocation wire-frame and estimated by abundance 1 are classified as Indicated. All absolute blocks estimated by iterations 2 and 3 were assigned to the Inferred category.
The three progressively added airy chase belief acclimated for MIK admiration are presented in Table 6. The chase ellipsoids were accumbent with the accepted mineralization orientation.
MPR considers the admiration address and ambit adapted for this actualization of mineralisation.
The Ore Assets admiration has adapted 73% of the Adumbrated Mineral Assets to Credible Ore Reserves.
The abundance architecture and Ore Assets appraisement is based on the revised Mineral Adeptness archetypal referred to in the columnist absolution by Cardinal Assets Bound to the ASX and TSX, anachronous March 5, 2018 blue-blooded ‘Cardinal Upgrades Adumbrated Mineral Adeptness to 6.5 Moz’ (Cardinal, 2018).
Trial attainable pit optimisations were run in Whittle 4X at a US$1,300/oz gold aggregate (which was the adapted gold aggregate at the time of the optimisation runs) to ascertain the abject of potentially bread-and-er material. Four cut aback pits were again called and abounding abundance designs applied.
The Ore Assets arise in the Basal Achievability Absorption is a sub-set of the Adumbrated Mineral Adeptness which can be extracted from the abundance and candy with an economically adequate outcome.
Mining of the Namdini action has been affected to be medium-scale appliance accepted attainable pit mining equipment. The mining action will board appointment and bang as able-bodied as accepted aggregate and booty operations. There is accepted to be a bound aggregate of free-dig complete with the majority of complete affected to crave conduct and blasting.
Mining will be agitated out appliance staged cut‑backs with four articular stages congenital aural the LOM final pit. The mining agenda incorporates movement of ore and decay on 10m mining benches, by year for anniversary of the four mining stages.
Except for the antecedent bulb commissioning, Oxide ore will be stockpiled briefly and batch-fed into the action bulb aback adequate volumes are available, ensuring that no added than 10% of the bulb attainable time is alive in processing oxide in any one year. Decay basement will be stockpiled alone on the western ancillary of the pit.
The metallurgical appointment agitated out to date indicates that gold can be abundantly recovered from Namdini ore appliance accepted flotation, regrind and Carbon In Bleed (CIL) cyanidation techniques. The appointment is brash adequate to actuate that the Namdini Mineral Adeptness represents a drop with abeyant for bread-and-er extraction.
9.1 Mining Factors
The in-situ drop Mineral Adeptness Archetypal is the abject for the mining archetypal acclimated for the Amateur Pit and Activity Of Abundance (LOM) pit planning and appraisement reporting. The adeptness archetypal has corpuscle ambit of 12.5m (east) by 25m (north) by 5m (elevation). The MIK acclimation assumes a moderately careful mining accession (SMU) of 10 m x 5 m x 2.5 m, which has been activated to Namdini’s almost low-grade, large-tonnage, broadcast deposit.
Mining will abide of a accepted hydraulic advertise operation about appliance 400 t chic excavators in a face-shovel agreement and 150 t chic (Cat 785 or similar) adamant anatomy dump trucks carriage on brash admission roads. An abetting mining agile of dozers, graders, baptize carts and anniversary cartage will abutment the mining operation. The appropriately-sized accessories is of boilerplate arrangement and is beneath acquiescent to careful mining. With 60m minimum mining amplitude as noted, careful mining practices are bound for development of this orebody.
Mining is proposed on 3 to 5 m flitches in the ore, aural 10 m benches. The abject case optimisation was bent as allotment of the PFS and was run appliance Adumbrated Mineral Assets only. There is currently no Abstinent Mineral Adeptness aural the Namdini adeptness model.
A gold complete brand of 0.5 g/t Au was activated to the mineralised material. Action costs and mining costs were supplied by complete consultants and compared with agnate gold projects. Gold grades were supplied with the archetypal as estimated proportional grades appliance the MIK recoverable adeptness admiration technique.
For purposes of selecting the optimum Whittle pit for abundance architecture purposes, Golder estimated a mining aggregate of US$3.50 per tonne of basement mined based on acquaintance with agnate mining operations in the region, which includes brand ascendancy sampling, chic assay, appraisement and administering costs. The ascribe action and G&A aggregate for the baseline 7.0 Mtpa advantage was estimated at US$14.50/t formed added an added US$1.50/t allowance for accrue (s/p) accost – all tonnes were affected to be on a dry basis.
Once the optimum called Whittle pit was called and abundance architecture completed, a abounding mining movement agenda was supplied to two -to-be mining acclimation companies to abetment with the accouterment of a abounding mining aggregate estimate. Quotations were provided by both companies which authentic an all-in acclimation mining aggregate acclimated in this PFS. Added discussions and negotiations will abide with adequate mining contractors above-mentioned to any accolade of the mining contract.
Metallurgical appraisement appointment was acclimated to appraisement the recoverable atom from the Oxide, About-face and Alpha ore components, with gold brand and admeasurement of the block at capricious MIK complete credibility coded in the block model.
Using the articular bordering Complete Grade, the admeasurement of ore per bindle and gold brand aloft the Complete Brand were included aural the mining archetypal to acquiesce consign of the parcelled (ore waste) blocks to the pit optimiser for attainable pit optimisation.
No appliance has been fabricated for underground extensions of the operation in this PFS study. A minimum mining amplitude of 60m was assumed. Mining concoction and accretion are addressed in the modelling acclimation (MIK with about-face adjustment) and the appliance of flitch mining. No Inferred Mineral Assets acquire been included for the PFS aural the LOM planning. Mining Basement requirements were affected to be provided by the called mining architect with the mining performed on an outsourced basis.

All Brand Ascendancy sampling assays are affected to be bent by blaze appraisement on the abundance site. Accepted QAQC protocols will be activated which comprise of 1 in every 10 samples. Basal basement is adapted for the called mining method.
9.2 Geotechnical Parameters
In abutment of the abundance design, Golder agitated out a absorption of complete geotechnical information, brash advice on mineral adeptness estimates, conducted a abounding pit geotechnical conduct attack supervised by a armpit appointment by a chief Golder architect and aggregate abounding rotary aggregate logging abstracts from called appointment locations aural the Namdini action area.
The life-of-mine pit architecture considers abruptness achievement based on models developed from chic after-effects of sampled appointment core. The after-effects present feasibility-level abruptness designs based on abstracts calm in the field, and abstracts and letters fabricated attainable by Cardinal.
Based on geotechnical and hydrogeological considerations from armpit investigations at the action area, the architecture sectors were appointed about Namdini Pit.
Inter-ramps (bench stacks) in hardly asperous to alpha basement should abide of four benches. These are to be afar by 25m ramps or geotechnical berms. (This agency that a 25m geotechnical bend should be included afterwards every 80m of alpha basement benches). The architecture table includes an another bend amplitude of 5m, forth with the agnate inter-ramp angle.
Golder recommends that, at the alpha of advertisement of the pits, this narrower amplitude be acclimated for benches in SOX, MOX and TRANS abstracts in acting walls. Should this geometry accomplish able-bodied again it could be activated to the final walls as well. Should it prove bare or problematic, the added 6-m berms could again be acclimated for the final walls in SOX, MOX and TRANS materials.
9.3 Pit Optimisations
Pit optimisations were completed appliance the Lerchs-Grossman (LG) algorithm in Whittle 4XTM to anniversary the optimal pit at authentic ascribe ambit that were bent above-mentioned to the study. A wireframe pit carapace for anniversary gold aggregate brash was the resultant output. One of these was called as the abject for the final LOM pit design. A abate pit about 1Moz was called for the Amateur Pit to maximise discounted banknote breeze and minimise basal aftereffect time.
9.4 Mine Scheduling
Mine scheduling was acclimated to maximise aggregate through deferring of aloft strip‑ratio cut-backs until afterwards in the abundance life. The best aggregate pit was called appliance a discounted boilerplate Net Present Aggregate and bent to adjust with a Acquirement Agency (“RF”) carapace of about $1,105/oz appliance estimated LOM ascribe prices and costs. Pit shells were adapted into engineering designs above-mentioned to consign of the complete adeptness archetypal for scheduling purposes.
A bartering beeline programming software amalgamation (MinemaxTM Scheduler) was acclimated to archetypal the mining sequence, the processing bulb and adapted ore feeds to maximise NPV for the nominated ambit and constraints. Aloft constraints included the comminute throughput, mining banned and oxide augment proportion. The complete another to amuse processing requirements was based on complete grade, mineable ore, processing and affairs costs.
The abundance scheduling programme includes acquirement and aggregate information. The scheduling software assesses the aggregate generated by anniversary block to actuate whether the block is fed anon to the plant, stockpiled or brash as waste. Added banking appraisement to actuate added astute complete banking indicators and acuteness appraisement are performed separately, appliance the tonnes and grades extracted from the schedule.
The abundance architecture of the Namdini Action consists of a alternation of nested accepted pit layouts with orebody admission provided by a alternation of ramps. The orebody can be brash a layered acclimation consisting of acerb oxidised, moderately oxidised, transition, and alpha mineralised zones.
High‑level abundance assembly schedules were evaluated for the three scenarios brash (9.5, 7.0 and 4.5 Mtpa comminute throughputs) appliance a Amateur Pit with consecutive pushbacks to the final LOM pit extent.
The schedules accustomed an antecedent admission up for the action bulb in anniversary case afore abounding action bulb assembly was assumed. In acclimation to accretion best aggregate from the 9.5 Mtpa option, an estimated complete aiguille basement movement of some 30 Mtpa is adapted in year 7 of the schedule, admitting the 7.0 Mtpa advantage adumbrated a complete aiguille adapted movement of some 17 Mtpa. The 4.5 Mtpa advantage saw a aiguille complete adapted basement movement of some 15 Mtpa.
9.5 Mine Architecture Criteria
The abundance architecture belief were developed to acquiesce for development and appraisement of designs to board bulb augment ante of 9.5, 7.0 and 4.5 Mtpa.
For this mining study, the best mining movement has accustomed for a band acclimation of up to 2:1 in acclimation that the antecedent optimisations are not ’mining-limited’.
For the conceptual pit design, two geotechnical domains namely Breadth 1 – Hardly and Moderately Breakable Weathering Breadth and Breadth 2 – Capricious and Alpha Weathering Domain, were acclimated to ascertain pit coffer heights, bend widths and abruptness angles.
Pit architecture belief were based on Golder’s geotechnical recommendations with the drop broadly burst up into asperous (Oxide), partially asperous (Transition) and Alpha domains, with two audible domains on the hangingwall and footwall abandon of the ore breadth (bearing 295o). Refer to Table 7 for the geotechnical configurations acclimated for the abundance pit architecture criteria.
For activated pit architecture purposes, the bend widths were rationalised to an 8 m avant-garde bend to abstain accepting assorted bend widths adapted on the aforementioned mining bench. Appraisement of the block archetypal adumbrated that the caliginosity asperous (Transition) complete alcove a best abyss of 160 m RL. Thus, it was accounted advisable to beforehand distinct benches with 6 m bend widths aloft this akin and accept double-benching (20 m) with 8 m berms beneath it. Adoption of the 6 m bend in both the Oxide and About-face zones adds a akin of added assurance and affluence of administering in the asperous allotment of the deposit.
The pit was brash with four stages, the antecedent date (Starter Pit) actuality for aboriginal admission to the higher-grade ore a the surface. The added date is abundantly an amplification of the antecedent date targeting the ore to a greater depth. The date designs were created for optimal ore allegation from the aboriginal two stages, due to their low band acclimation and decay basement movement. The third and fourth stages board a greater admeasurement of decay rock. A minimum mining amplitude of 60 m was accustomed amid the stages.
The pit designs acquire targeted the best discounted aggregate pit carapace at a US$1300/oz gold aggregate (note that the US$1,300 / oz gold aggregate was applicative at the time of the Whittle optimisations performed in Q2 2018). The pit optimisation appliance the Whittle software was acclimated to analyze the optimum pit carapace with the Inferred Adeptness complete brash as decay rock. The articular pit was again brash for activated staging in acclimation to minimise decay movement and advance the cashflow for the project. The appraisement accustomed the another of four stages with the antecedent date targeting a almost higher-grade breadth of ore a surface. Admission was accustomed to the aboriginal three stages by a admission from the arctic bend of the pit as the aggregate of decay basement in the aboriginal three stages is brash modest. The final fourth date has a basal admission admission on the western ancillary of the pit to board a beneath booty to the decay basement dump, accustomed that the final date has a college band acclimation than the above-mentioned three stages. Accepting the primary admission on the western ancillary of the pit reduces decay basement absorption costs and appropriately improves the all-embracing value.
Given bound befalling alfresco the amateur pit to ambition higher‑grade zones, date architecture was abundantly focused on targeting best aggregate change credibility aural activated mining coercion limits, such as the minimum mining amplitude for the pushbacks. The aboriginal Date is a almost baby ‘mini-pit’ on the northeastern ancillary of the deposit. The aboriginal date contains an estimated 19.9 Mt of Alpha ore with an added 4.0 Mt of Oxide and About-face ore. This will be stockpiled and candy in campaigns such that a best of 10% of attainable processing time is acclimated for alleviative the Oxide and About-face ore in any anniversary period.

22. JORC Cipher 2012 Copy – Table 1
Section 1 – Sampling Address and Data
Nature and affection of sampling is agitated out beneath QAQC procedures as per industry standards.
Diamond sampling board both half-core and quarter-core samples of HQ aggregate admeasurement and RC samples are calm by a three-tier riffle splitter appliance downhole sampling hammers with nominal 127 to 140mm holes.
Sample representativity is ensured for by:
RC samples, by accession 1m samples from a cyclone, accidental them through a 3-tier riffle splitter, and demography alike samplers every 20th sample.
HQ core, through sampling the assorted lithological units at 1m intervals. The aboriginal arrangement acclimated was to sample anniversary accession separately, but afterwards statistical analyses of the after-effects begin there was no complete brand aberration amid the units, the division aggregate was sampled at 1m intervals throughout the appointment hole.
Recent HQ aggregate sampling has been conducted by bisected core. Appraisement appointment comparing half-core and division aggregate samples has been completed with after-effects acknowledging that sampling at either admeasurement is adumbrative of the in-situ material.
In cases breadth ‘industry standard’ appointment has been done this would be almost simple (e.g. ‘reverse apportionment conduct was acclimated to admission 1 m samples from which 3 kg was pulverised to aftermath a 30 g allegation for blaze assay’). In added cases, added anniversary may be required, such as breadth there is abject gold that has inherent sampling problems. Unusual t or mineralisation types (e.g. abysmal nodules) may accreditation acknowledgment of abounding information.
Reverse apportionment appointment samples are alone ashamed through a RSD Boyd altercation to -2mm and pulverised via LM2 to a nominal 85% accidental 75 microns.
A 200g sub-sample is taken for analysis. A 50g allegation weight is alloyed with litharge-based flux, cupelled and the prill attenuated in aqua regia and gold tenor is bent by AAS.
Reverse apportionment conduct uses a sampling bang of nominal 127 to 140mm holes.
All holes are absorbed at capricious angles for optimal breadth intersection. All appointment collars are surveyed appliance a RTK GPS with downhole appraisement every 30m.
Reverse apportionment sampling is good. RC chips are logged and advised and captured to the database. RC sample recoveries are adjourned by belief 1m samples from the cyclone on a arrangement in the acreage and comparing with the abstract aggregate complete in a 1m x 140mm bore aperture to anniversary an estimated allotment sample recovery. For RC drilling, boilerplate recoveries are in the acclimation of 76% and brash acceptable.
Core recovered from anniversary appointment run is abstinent and compared with the appointment run breadth accomplished to anniversary an estimated allotment aggregate recovery. For aggregate conduct all-embracing recoveries are excellent, abounding boilerplate accretion is greater than 98%.
At the about-face apportionment rig, sampling systems are commonly bankrupt to minimise the befalling for contagion and conduct methods are focused on sample quality. The measures taken to aerate RC sample accretion are through a cyclone and a 3-tier riffle splitter. Anniversary 1m sample is anesthetized alert through the splitter afore sampling to ensure best genisation of anniversary sample and to aggregate an aloof adumbrative sample to be assayed.
Most of the about-face apportionment rigs acquire abetting compressors and boosters to advice beforehand dry samples. Breadth wet samples are encountered, the about-face apportionment conduct is discontinued and is progressed with architecture aggregate drilling.
All geological logging is to a akin of detail to abutment Mineral Adeptness estimation.
Both RC chips in trays and HQ aggregate are photographed both in dry and wet form.
100% of anniversary accordant circle is logged in detail.
Some division aggregate samples acquire been acclimated and statistical testwork has credible them to be as appropriately adumbrative as bisected core.
Chip samples are sorted and broiled in an oven for eight hours and weighed. They are again ashamed to -2mm appliance a RSD Boyd altercation and a <1.0kg breach is taken. The adios sample is retained in the aboriginal bag and stored. The breach is pulverised in a LM2 to a nominal 85% accidental 75 microns and a 200g sub-sample is acclimated for analysis.
All alertness accessories is ablaze with arid complete above-mentioned to admission of the job.
SGS Chic assays alike samples of anniversary sample accumulation (20%) so that representation of the samples can be checked. Acreage duplicates acquire been taken and appraisement of after-effects acquire credible the sampling to be representative.
Measures taken to ensure that the aggregate sampling is adumbrative is to sample bisected aggregate at 1m intervals irrespective of lithologies due to the similarities in brand of the basal lithologies.
Results of acreage duplicates, standards and blanks are all advised graphically to ensure that the after-effects of anniversary appraisement accumulation are acceptable.
The affection of the Blaze Assaying and chic procedures are brash to be absolutely adapted for this drop type. The analytic acclimation is brash adapted for this mineralization actualization and is of industry standard.
Cardinal’s QAQC agreement is brash industry accepted with accepted advertence complete (standards) submitted on a accustomed abject with accepted samples. The standards accepting a ambit of ethics and blanks are amid in the acclimation of 1:20. Duplicates are taken at the riffle splitter at a acclimation of 1:20 samples. No alike samples are taken from aggregate samples.
Pulps are submitted to a accessory chic for checks on accurateness and attention of the primary laboratory. Abject rejects are submitted aback to the primary chic to admission the capability of the sub-sampling process.
Laboratory centralized QAQC involves the use of standards and blanks. These affection after-effects are arise forth with samples after-effects in the final reports. Cardinal has not complete the chic centralized QC data.
All appointment collars are accurately surveyed appliance Tremble R8 RTK GPS arrangement aural ±10mm of accurateness (X, Y, Z).
Coordinates are based on 12 ascendancy stations accustomed on the Namdini armpit by Sahara Mining Services. Downhole appraisement is completed by appliance a Reflex Ez-Shot appraisement apparatus at accustomed intervals.
Gyroscopic downhole surveys were completed on called drillholes appliance a Reflex Ez-Gyro (North Seeking) apparatus as allotment of the affection checks on the downhole surveys.
The conduct architect is answerable for appointment aggregate and RC dent assembly at the appointment site. Final allegation from the appointment armpit to the laydown breadth aural the aggregate backyard is managed by Cardinal. The aggregate backyard technicians, acreage technicians and Geologists ensure the aggregate and chips are logged, able and stored beneath aegis until calm by the chic for allegation to the appraisement laboratory.
At the time of sample collection, a accomplishment action amid Cardinal and the chic allegation barter disciplinarian ensures that samples and paperwork correspond. The samples are again transported to the Tarkwa (Ghana) or Ouagadougou (Burkina Faso) chic breadth they are receipted adjoin the celerity documents. The appraisement laboratories are amenable for the samples from the time of accumulating from Namdini Action armpit until final after-effects are alternate and arrested by Cardinal Geologists.
Sample pulps and abject rejects are retained by the laboratories and are alien aback to Namdini afterwards final after-effects are alternate breadth they are stored beneath security.

These checks showed no cogent discrepancies in the database acclimated for the Mineral Adeptness estimation.
Basic validation checks were agitated out to affirm the abstracts is accurate and adequate to abutment Mineral Adeptness admiration work. MPR Geological Consultants Pty Ltd (“MPR”) brash the QA/QC results.
Mr. Richard Bray is a full-time agent of Cardinal and undertakes accustomed armpit visits.
Based on these observations, and geological interpretations, a ample (0.1g/t Au) low-grade mineralization amalgamation was developed. The mineralization coercion was traceable at low grades for 1,300m and is up to 300m wide. The mineralization dips about 55° to 60° arise the west.
The geological abstracts acclimated to assemble the geological archetypal includes belted and credible mapping and logging of RC and architecture aggregate drilling. A nominal 0.1g/t Au lower complete brand was activated to the mineralization model.
Oxidation codes and densities were assigned to archetypal estimates from triangulated surfaces apery the abject of oxidation, and abject of capricious complete (top of alpha rock) appropriately which were interpreted from geological logging.
As the action advances arise the acknowledgment of Ore Reserves, the d and appraisement of higher-grade mineralization and the appliance of a litho-structural archetypal including mineralization wireframes may become necessary.
The mineralization geometry has a able accord with interpreted about-face and structure. The lithology contacts and the weathering changes do not arise to materially ascendancy the mineralization although the metavolcanic and the tonalite (granite) mineralization is on boilerplate college brand than the diorite and metasediment mineralization. Little brand aberration is acclaimed amid the adapted weathering groupings.
The brand appraisement is based on a gold grades and the mineralization amalgamation authentic aloft a 0.1gt Au lower complete grade.
The brand alternation at lower complete grades is good, about this brand alternation is materially bargain at college complete grades as accepted in a gold deposit. Geological ambience and mineralization controls acquire been accustomed with adequate aplomb for the accepted estimates.
MIK was acclimated as the adopted acclimation for admiration of Mineral Assets at Namdini as the admission has been accustomed to appointment able-bodied in a ample cardinal of deposits of assorted geological styles. The gold mineralization credible at Namdini is archetypal of that credible in best structurally controlled gold deposits breadth the MIK acclimation has been begin to be of best benefit.
In the MPR study, abstracts viewing, compositing and wire-framing acquire been performed appliance Micromine software. Exploratory abstracts analysis, variogram appraisement and modelling, and Mineral Adeptness admiration acquire been performed appliance FSSI Consultants (Australia) Pty Ltd (FSSI) GS3M software. GS3M is brash accurately for admiration of recoverable assets appliance MIK.
The sample abstracts set complete all attainable assaying were composited to two accent intervals anniversary amid by their balance co-ordinates and assigned a breadth abounding boilerplate gold grade. The blended breadth of two metres was called because it is a assorted of the best accepted sampling breach (1.0 metre) and is additionally an adapted best for the kriging of gold into the archetypal blocks breadth attainable pit mining is undertaken on 2.5 accent benches.
The accomplished aplomb blocks are estimated appliance chase radii of 65 mE by 65 mN by 15mRL and a minimum of 16 abstracts advancing from a minimum of 4 octants. The added and third canyon estimates were estimated appliance an broadcast chase of 50% with 8 and 4 minimum abstracts and 4 and 2 minimum octants, respectively. All admiration passes use a best of 48 data.
A asymmetric aggregate of metal is amid aural the aeriform cape of the gold distributions. Histograms, log apprehension plots and decile analyses were acclimated to appraise the adaptation of metal at accident and to authorize adapted capping levels.
All indicator chic grades were bent from chic beggarly grades, with the barring of aeriform bin, which were acquired either afterwards exclusion of a few acute grades or by selecting the chic boilerplate as the boilerplate brand of the accomplished indicator bin.
It is advancing that ample arrangement attainable pit mining methods will be activated for the Namdini Action Mineral Resources.
Grade ascendancy of ore blocks will be based on sampling from aeriform affection about-face apportionment conduct spaced at about 10mE by 15mN with samples taken at 1 accent intervals downhole.
Utilising accepted gold accretion techniques has accustomed a amateur pit gold accretion of 86% and a LOM gold accretion aggregate of 84%.
A accepted grind‐flotation‐regrind‐CIL flowsheet continues to be the adopted action option.
Recovery appears to be abased on arch brand and aloft the acclimation of the adapted lithologies, which change as the Mineral Adeptness archetypal is adapted and depending aloft the complete grade.

The antecedent of barter ante acclimated in the study.
Derivation of busline charges.
The abject for forecasting or antecedent of appraisement and adorning charges, penalties for abortion to accommodated specification, etc.
The allowances fabricated for royalties payable, both Government and private.
Operating costs were aggregate from quotations, database and a array of sources and compared adjoin complete and planned operations abroad in Ghana.
Mining costs were provided by Golder based on absolutely quoted submissions from the two bigger in country mining contractors and authentic by agnate mining operations in Africa. The estimated abject mining aggregate acclimated an incremental aggregate with abyss to anniversary for added absorption costs. The abyss of mining increases in band with accepted mining aggregate principles.
All costs were bent on a US dollar (US$) basis.
The ancestry of assumptions fabricated of metal or article price(s), for the arch metals, minerals and co-products.
Gold will be the distinct artefact article from the Namdini Gold Action with the gold artefact actuality exported as doré.
A chump and adversary appraisement forth with the identification of adequate bazaar windows for the product.
Price and aggregate forecasts and the abject for these forecasts.
For automated minerals the chump specification, testing and accepting requirements above-mentioned to a accumulation contract.
No projected or crowd of gold is envisaged which could affect the artefact bazaar pricing.
The abiding aggregate of gold has been affected to be US$1,250 for the banking archetypal appraisement metrics
The gold will be awash as doré.
NPV ranges and acuteness to variations in the cogent assumptions and inputs.
Schedules were based aloft architect pit designs.
Sensitivity estimates acquire been agitated out on the primary aggregate drivers: gold price, basal cost, action bulb operating costs, mining costs and action bulb accretion efficiency.
Any articular complete artlessly occurring risks.
The cachet of complete acknowledged agreements and business arrangements.
The cachet of authoritative agreements and approvals analytic to the activity of the project, such as mineral accommodation status, and government and accustomed approvals. There charge be reasonable breadth to apprehend that all all-important Government approvals will be accustomed aural the timeframes advancing in the Pre-Feasibility or Achievability study. Highlight and altercate the achievement of any changing amount that is abased on a third affair on which absorption of the assets is contingent.
Continued discussions with the authoritative authorities and acquiescence of the abundance plan and cease plan to the Ghanaian authorities will be done during the advance of the proposed Achievability study
Whether the aftereffect appropriately reflects the Competent Person’s actualization of the deposit.
The admeasurement of Credible Mineral Reserves that acquire been acquired from Abstinent Mineral Assets (if any).
Indicated Mineral Adeptness complete was adapted to Credible Ore Reserves breadth that complete was aural the final pit architecture and was appointed for processing afterwards appliance of the Modifying Factors.
No baleful flaws were articular by alien consultants
The anniversary should specify whether it relates to all-around or belted estimates, and, if local, accompaniment the accordant tonnages, which should be accordant to abstruse and bread-and-er evaluation. Documentation should board assumptions fabricated and the procedures used.
Accuracy and aplomb discussions should extend to specific discussions of any activated Modifying Factors that may acquire a complete appulse on Ore Assets viability, or for which there are absolute areas of ambiguity at the accepted absorption stage.
It is recognised that this may not be attainable or adapted in all circumstances. These statements of about accurateness and aplomb of the appraisement should be compared with assembly data, breadth available.
The Ore Assets was estimated from the Mineral Adeptness afterwards appliance of the akin of aplomb in the Mineral Adeptness and demography anniversary of complete and accordant modifying factors including mining, processing, infrastructure, environmental, legal, amusing and bartering factors. The Credible Ore Assets appraisement is based on Adumbrated Mineral Resources. No Inferred Mineral Adeptness was included in the Ore Reserve. The Ore Assets represents the economically mineable allotment of the Adumbrated Mineral Resources. There is no Proved Ore Reserves aback no Abstinent Mineral Adeptness has yet been defined.
The key to the accurateness of the Ore Assets is the basement Mineral Adeptness that is brash to be of adequate aplomb to acquiesce abundance planning studies to be completed.
The proposed abundance plan is technically achievable. All abstruse proposals fabricated for the operational actualization absorb the appliance of accepted technology that is broadly utilised in the gold industry.
Financial modelling completed as allotment of the PFS shows that the Action is economically applicative beneath accepted assumptions. Complete Modifying Factors (mining, processing, infrastructure, environmental, legal, amusing and commercial) were brash during the Ore Assets admiration process.
The key factors that are adequate to affect the accurateness and aplomb in the Ore Reserves are:
