Sampling Techniques

• Nature and quality of sampling (e.g. cut channels,random chips, or specific specialied industrystandard measurement tools appropriate to the minerals underinvestigation, such as downhole gamma sondes, orhandheld XRF instruments, etc.) These examples should not be taken aslimiting the broad meaning of sampling. 

• Include reference to measures taken to ensure samplerepresentivity and the appropriate calibration of any measurementtools or systems used. 

• Aspects of the determination ofmineralisation that are Material to the PublicReport. 

In cases where ‘industry standard’ work has beendone, this would be relatively simple (e.g. ‘reverse circulationdrilling was used to obtain 1 m samples from which 3 kg was pulverisedto produce a 30 g charge for fire assay’). In other cases, moreexplanation may be required, such as where there is coarse gold thathas inherent sampling problems. Unusual commodities or mineralisationtypes (e.g. submarine nodules) may warrant disclosure of detailedinformation.

No drilling has been undertaken on Vavoua PR-454.

Soil samples collected for Vavoua PR-454 are to beassayed by fire assay at Bureau Veritas laboratory in Côted’Ivoire, and selected samples analyses by PortablePPB at the SEMSfield compound in Zuénoula.

SOIL SAMPLING STAGES

• Stage 1: Initial, permit-wide,broad-spaced soil sampling on an 800m x 800m grid 

• Stage 2: Gold anomalous clustersand trends defined by multiple anomalous soil samples are theninfilled with soil samples collected on 400m x 400m grid.  

• Stage 3: Coherent gold soilanomalies are then infilled with soil samples collected on a 100m x50m grid 

• All samples are to be analysed by fire assay at BureauVeritas laboratory in Côted’Ivoire, with selected samples analysed byPortablePPB at the SEMS compound in Zuénoula.  

• The assay results from this higher-density sampling(100m x 50m) permit trenching and drilling to be planned.  

SOIL SAMPLING PROCEDURES

• The highly experienced consulting group SEMSExploration Services (SEMS) has been contracted by MGA to conduct thesoil sampling 

• Up to 4 sampling crews may be active 

• The MGA Exploration Manager was onsite at the start ofthe field program to instruct the sampling crew on the StandardSampling Procedure required by MGA  

• MGA provided SEMS Exploration Services with an Exceltable listing the designated sample point locations using WGS-84 UTMzone 29N coordinates 

• Each soil sample is collected from within 50 metres ofthe designated sample point, with the actual sample point thenrecorded 

• At each sample point: 1) the organic rich soil isbrushed away, 2) a 40cm deep hole dug and the sample collected bytaking a channel-cut along the bottom 20cm of the hole, 3) 1000g ofthe minus 2mm sieved fraction of each sample is collected from thesample point, 4) gold is  determined by fire assay (LDL 2ppb) andwith selected samples also analysed by PortablePPB (LDL ~6dU) 

• Duplicate samples are collected every 20th sample,certified reference material (CRM) inserted every 20th samples andblanks inserted every 20th sample 

• PortablePPB is a partial gold extraction technique,whereas fire assay is a total gold extraction technique 

• Samples are processed and stored at the secure SEMSfield compound in Zuénoula. 

Drilling Techniques

PORTABLE-PPB ANALYSIS

• Selected 500g sub-samples are analysed using thepatented detectORE™ process developed by Portable PPB Pty Ltd inAustralia 

• The process involves a partial extraction using thesafe, non-dangerous GLIX-20® reagent that is akin to traditional BLEG(which uses a cyanide leach) 

• The 500g samples are added to the reagent and tumbledfor 12 hours, into which the detectORE™ collector device had beeninserted 

• After the bottle roll process has completed, thecollector device is removed, washed, and dried prior to reading on aVanta M (VMR) pXRF loaded with Evident/Olympus’s detectORE™mode 

• The entire process is managed using Portable PPB’sPortable Lab Information Management System (pLIMSTM), which recordsall aspects of the sample throughput, including QAQC and control ofthe pXRF via the Application Programming Interface toOlympus/Evident’s co-developed detectORE™ mode.  

• Certified Collector Devices (CCDs) supplied byPortablePPB with known quantities of gold ranging from 0 -1000 ppb areused to check that the pXRF was functioning correctly and that theinstrument settings were as intended. One CCD serves as a blank. 

• The pLIMS software confirmed the instrument settingsare correct and the VMR is operating as expected, controlled by thepLIMS API and Evident’s detectORE™ firmware.

• The verification of significant intersections by eitherindependent or alternative company personnel. 

• Theuseoftwinnedholes. 

• Documentationofprimarydata, data entry procedures,data verification, data storage (physical and electronic) protocols. 

• Discussanyadjustmentstoassay data. 

• The detectORE™ process is checked in accordance withPortablePPB’s recommended processes and procedures. These includethe insertion of 400g reference materials (RMs).  

• The RMs comprise mixtures of commercial CertifiedReference Materials (CRMs) and barren regolith material. The RMs areof known, but uncertified gold concentration and are used to checkthat the leach and collect process has worked as intended during the12-hour bottle roll.  

• RMs were inserted at a rate of 1 every 44 samplesthroughout the sample batches. The RMs were checked against PortablePPB’s cloud-based database and passed within the accepted toleranceranges for the technique, currently 20% (3 sigma).  

• The pXRF instrument settings are checked using a range of Certified Collector Devices, which are usedto confirm the pXRF is operating as expected. The pXRF spectral filesare reviewed by Portable PPB’s cloud and SME procedures.  

FIRE ASSAY ANALYSIS

• All samples are analysed for gold by fire at BureauVeritas laboratory in Cote d’Ivoire 

• The original 1000g -2mm sample collected in the fieldis split into two 500g sub-samples using a riffle splitter. One 500gsub-sample is kept as a reference sample and may be used forPortablePPB analysis. The second 500g sub-sample is used for goldanalysis by fire assay (Lab Code: FE450, LDL 2ppb) 

• At the laboratory, the 500g -2mm sub-sample is driedand pulverised to 85% passing 75 microns. 

• This sample pulp is then mixed with a combination ofchemical reagents, which when heated to high temperatures results inthe formation of a lead button and slag. The lead button that containsthe precious metals (including gold) is cupelled at high temperature.The lead is adsorbed by the cupel leaving behind a bead that containsthe precious metals. 

• The bead is acid digested and analysed by AAS, with alower detection limit of 2ppb Au 

Location of Data Points

• Accuracy and qualityof surveysused to locate drillholes (collar and down-hole surveys), trenches,mine workings and other locations used in Mineral Resourceestimation. 

• Specification of the grid system used. 

• Quality and adequacy of topographic control. 

• A handheld GPS is used to locate the soil datapositions, with a +/-5m vertical and horizontal accuracy 

• Sample locations (UTM WGS-84 zone 29N) and sampledescriptions are noted on a standard form in the field and entered ona computer of an evening 

• GPS measurements of sample positions are sufficientlyaccurate for exploration targeting of gold systems. 

Data Spacing and Distribution

• Data spacing for reporting ExplorationResults. 

• Whether the data spacing and distribution is sufficientto establish the degree of geologicalandgradecontinuity appropriate for the Mineral Resource and OreReserve estimation procedure(s) and classifications applied. 

• Whethersamplecompositing hasbeenapplied. 

• An 800m by 800m offset grid pattern has been adoptedfor the entire project area, excluding areas of irrigated sugar caneand villages.  

• Broad-spaced soil sampling (800m by 800m) and low levelgold fire assay analysis (LDL 2ppb) is considered an effectivetechnique for identifying and delimiting gold anomalous clusters andtrends, which are then followed up with higher density sampling at400m 400m and 100m x 50m as the next phases ofsampling ahead of trenching and drill testing of coherent gold soilanomalies. 

Orientation of data in relationto geological alstructure

• Whether the orientation of sampling achieves unbiasedsampling of possible structures and the extent to which this is known,considering the deposit type. 

• If the relationship between the drilling orientationand the orientation of key mineralised structures is considered tohave introduced a sampling bias, this should be assessed and reportedif material. 

• The sample location configuration has been deliberatelyplanned to avoid directional bias. 

Sample security

• The measures taken to ensure sample security. 

• 1000g of the -2mm sieved fraction of soil samples arecollected in plastic bags, assigned individual sample numbers andtransported to the secure SEMS lab and compound in Zuénoula 

• Samples are analysed by fire assay at Bureau Veritas in Côte d’Ivoire and are personally transported to the laboratory by a seniormember of the SEMS crew.  

Audits or Reviews

• The results of any audits or reviews of samplingtechniques and data. 

• The sampling and assay techniques adopted byMetalsGrove has been effectively used in the Vavoua-Kounahiridistrict, and more widely in Cte d’Ivoire, todefine drill targets and it is considered an effective initialapproach for defining gold anomalous lithogeochemical trends.
