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 fromwhich 3 kg was pulverised to produce a 30 g charge for fire assay’).In other cases, more explanation may be required, such as where thereis coarse gold that has inherent sampling problems. Unusualcommodities or mineralisation types (e.g. submarine nodules) maywarrant disclosure of detailed information.

No drilling has been undertaken. The current ASXannouncement presents initial results of a soil geochemical surveybeing undertaken on the Zuénoula project PR-750 in Coted’Ivoire.

Soil Sampling (PortablePPB): Initial broad-spaced (1km by 1km) soil sampling supported byrapid field analysis of samples using the PortablePPB analyticaltechnique is being undertaken so that gold anomalous trends can beidentified and infill sampling conducted to define drill targetsbefore the field crew is demobilized.

• The highly professional and experienced consultinggroup SEMS Exploration Services has been contracted to conduct soilsampling and assay the samples using their PortablePPB mobilelaboratory 

• 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 100 metres ofthe designated sample point, with the actual sample point thenrecorded 

• At each sample point: 1) the organic rich soil isbrushed away, 2) a 15cm deep hole is dug and the sample collected bytaking a channel-cut along the entire length of the hole, 3) 800g ofthe minus 2mm sieved fraction of each sample is collected from thesample point, 4) at the field lab in Zuénoula, a hand-held XRF (pXRF)is used to determine and record arsenic, copper, nickel, tungsten,iron and manganese concentrations 5) gold is  determined using thePortablePPB technique and results are reported in dU, an partial extracted gold measurement units 

• Duplicate samples are collected every 20th sample andgiven the next sample number 

• No Standards other than instrument calibrationstandards are used to avoid low-level gold contamination. Goldanomalous samples sites (+15dU Au) are to bere-assayed using the fire assay technique atMSALabs in Yamoussoukro 

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

• Assay results are reported to MetalsGrove within 48hours so that infill sampling can be planned and scheduled. 

Drilling Techniques

• Drill type (e.g. core, reverse circulation, open-holehammer, rotary air blast, auger, Bangka, sonic, etc.) and details(e.g. corediameter,tripleorstandardtube,depthofdiamond tails, face-sampling bit or other type, whether coreis oriented and if so, by what method, etc). 

• No drilling has been undertaken.

their derivation, etc.

• Nature of quality control procedures adopted (e.g.standards, blanks, duplicates, externallaboratorychecks)and whether acceptable levels of accuracy (i.e. lack of bias)and precision have beenestablished. 

• Samples are analysed using the patented detectORE™process developed by Portable PPB Pty Ltd in Australia 

• 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 400g 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 ProgrammingInterface to Olympus/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 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 rangeof Certified Collector Devices, which are used to confirm the pXRF isoperating as expected. The pXRF spectral files are reviewed byPortable PPB’s cloud and SME procedures.  

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 WGS84 zone 29N) and sampledescriptions are noted on a standard form in the field and enteredinto a computer of an evening 

• GPS measurements of sample positions are sufficientlyaccurate for first pass, board-spaced sample collection.  

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. 

• The 1km by 1km offset soil sample pattern over thepermit area, excluding areas of irrigated sugar cane, is considered aneffective technique for identifying and delimiting gold anomaloustrends, which are then followed up with higher density sampling, with400m by 400m as the next phase and then further infill as required todefine well constrained drill targets. 

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. 

• 800g 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 for golddetermination by PortablePPB.  

Audits or Reviews

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

• The sampling and assay technique adopted by MetalsGrovehas been effectively used in the Vavoua-Kounahiri district, and morewidely in Cote d’Ivoire, to define drill targets and it isconsidered an effective initial approach for defining gold anomalouslithogeochemical trends.
