Criteria

Explanation

Sampling techniques

• Nature and quality of sampling (eg 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.

• Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used.

• 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 (eg '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 (eg submarine nodules) may warrant disclosure of detailed information.

2019 Diamond Drilling

·; Assays have been received for 3 diamond drill holes. In aggregate, 285m of drilling was completed.

·; Hole 2019WTD001 failed to reach target depth. Subsequent hole 2019WTD003 was a step back hole and reached target depth.

·; Samples consist of diamond drill core (HQ and NQ sizes) cut in half.

·; All available core was cut and sampled. Sampling interval is generally 1m or 0.5m, but respects geological contacts in places. Sampling was carried out to Greatland internal protocols and QAQC procedures.

·; Entire samples were crushed then pulverised to a nominal 85% passing 75 microns. The resulting pulps were analysed for Au (50g charge, fire assay) and multi-element geochemistry (four acid digest ICP-MS).

·; The method of sampling is industry standard for reporting of Exploration Results.

·; Locations and orientation of 2019 drill holes for this release are tabulated in Appendix I.

 Historic RC Drilling

·; RC sampling was carried out using Greatland internal protocols and QAQC procedures.

·; One metre samples were collected from the cyclone into a plastic bucket and laid out generally in rows of 50.

·; RC samples were composited to 4m lengths via 'spear' sampling the individual 1m intervals. Samples were then taken to the laboratory and pulverised.

Drilling techniques

• Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg 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).

2019 Diamond Drilling

·; Drilling was undertaken using a track mounted Coretech CSD1800 drill rig. The drill rig is capable of ~1000m NQ.

·; Drill holes were cased with HWT casing to ~3m. HQ sized drill core from 0m to ~20m followed by NQ drill core from 20m to end of hole.

Historic RC Drilling

·; Drilling was undertaken using a track mounted RC drill rig.

·; RC Drill holes - 134mm face sampling RC bit to end of hole.

Drill sample recovery

• Method of recording and assessing core and chip sample recoveries and results assessed.

• Measures taken to maximise sample recovery and ensure representative nature of the samples.

• 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.

2019 Diamond Drilling

·; Length based core recovery is measured from reassembled core for every drill run. Data is recorded into laptop computer using 'LogChief' - geological logging software.

·; Core recovery is high (93%). The drilling method employed leads to very high recoveries.

·; Due to consistently high recoveries, no relationship between grade and recovery is evident.

Historic RC Drilling

·; RC sample recovery and quality was recorded via visual estimation of sample volume and the condition of drill spoils.

·; Recovery ranges from 90-100%, with only occasional recoveries of less than 70%. Sample recovery was maximized by maintaining dry samples (dry drilling conditions) as much as possible.

·; Due to consistently high recoveries, no relationship between grade and recovery is evident.

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.

• Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography.

2019 Diamond Drilling

·; All drill core/samples were geologically logged for lithology, mineralogy, alteration, veining, sulphide occurrences, structure and geotechnical data. This logging includes both qualitative and quantitative components. All core is digitally photographed.

·; Logging is recorded directly into a laptop computer using 'LogChief' - geological logging software. This software has 'look-up tables' that do not allow for invalid entries. Additional validation is then carried out when data is transferred to Greatlands database managers.

·; All samples are analysed in the field using a pXRF (Olympus Vanta handheld - model VMR) for the purpose of geochemical interpretation.

·; All core is analysed in the field using a Minalyze unit. This collects ultra-high resolution photography, and continuous XRF measurements.

• Whether sample sizes are appropriate to the grain size of the material being sampled.

2019 Diamond Drilling

·; All sampled core was cut with a core saw in a consistent way that preserved the bottom of hole reference line, where present. Sampling interval is generally 1m or 0.5m, but respects geological contacts in places.

·; Sample preparation included drying, crushing and pulverising in full to a nominal 85% passing 75 microns.

·; All staff were adequately trained for all sampling steps, with geologists checking sample sheets prior to loading into the database.

·; The sample sizes are considered appropriate for the style of mineralisation encountered in the region.

·; No field duplicates have been collected/reported.

Historic RC Drilling

Drill hole Information

• A summary of all information material to the understanding of the exploration results including a 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 metres) of the drill hole collar

• dip and azimuth of the hole

• down hole length and interception depth

• hole length.

• 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.

·; A tabulation of the collar details and significant intersections is contained in Appendix I.

·; Reports prepared by Greatland Pty Ltd are available to view on: www.greatlandgold.com

Data aggregation methods

• In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated.

• Where aggregate 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.

• The assumptions used for any reporting of metal equivalent values should be clearly stated.

• Exploration results are reported by length weighted average.

• Warrentinna - Significant intersections are reported as minimum length of 1m - greater than or equal to 0.2ppm Au with up to 4m of internal dilution and intervals greater than or equal to 1ppm Au with zero metres of internal dilution. Au is reported to two significant figures.

Relationship between mineralisation widths and intercept lengths

• These relationships are particularly important in the reporting of Exploration Results.

• If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported.

• If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg 'down hole length, true width not known').

• Down hole lengths are reported, true width is not known.

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 plan view of drill hole collar locations and appropriate sectional views.

• Appropriate diagrams are available with this report.

Balanced reporting

• Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results.

• The company believes this announcement is a balanced report, and that all material information has been reported.
