§ Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation)

§ 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

§ An RC Drill rig was used to complete drill holes at Chilly prospect and pre- collars on the Scallywag and Skylar tenements for follow up tails with DD rig.  The diamond core rig was also used to drill mud rotary from surface to competent ground or through the cover sequence, before completing the hole with a diamond core tail in competent ground/basement, to obtain representative samples in an industry standard method.

§ Greatland RC samples consisted of cone split representative 1m crushed rock samples with average weights of less than 5kg.

§ Greatland diamond core samples comprise half core material in generally 1m lengths (NQ and HQ diameter core). All Proterozoic basement and generally the basal 10-20m of the Permian cover was sampled where intersected with Diamond or RC drilling. Core was cut using an automated core-cutter.

§ No regular sampling was completed for mud rotary drilling as the sample is considered contaminated.

§ Cutting of core adjacent to downhole orientation line or, where un-oriented and possible, orthogonal to visible geological structures such as bedding, foliation; ensures sample representivity.

§ 50% of the core is retained for future check logging, re-sampling and QA/QC

Ground Gravity Data Collection:

In late June through early July 2024, Daishsat on behalf of Greatland Gold undertook the collection of 1786 individual station gravity measurements on a predominantly 100x100m east - west orientation going out to 200 x200m spacing on the margins of the survey. The data collection traverses were customised to avoid crossing sand dunes. The survey covered the northern 5.2km of the Budjidowns tenement inclusive of the Atlantis prospect.

Scintrex CG-5 Autograv gravity meters were used for gravity data acquisition and base station control. Leica GX1230 GNSS receivers were used for gravity station positional acquisition. All gravity and GNSS data were acquired using Daishsat UTV methods, with 2 crews operating concurrently onsite.

One new GNSS base station, numbered 1600, was established and utilised for reduction and drift control for the survey.

§ 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)

§ RC drilling was completed at Chilly.

§ For Havieron region drilling RC or mud-rotary pre-collars were followed by PQ and/orHQ then NQ diamond drill core to EOH

§ The core is oriented using a Reflex mark III tool, nominally every core run (around 6m)

§ 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

§ Recovery is measured on core and reconciled against driller's depth blocks in each core tray. Basement core recovery is typically around 100%

§ No specific measures have been taken to maximise recovery, other than employing skilled drillers

§ Half core cut at a consistent spacing from orientation lines assist in sample representivity

§ No relationship between recovery and grade has been observed

§ To ensure sample quality from RC drilling, a face sampling drill bit was used and an attempt was made to keep the sample dry to avoid downhole smearing. Where this was not possible the sample was noted as wet in the sample log. Where this is the case some potential for sample bias may exist

§ 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

§ The total length and percentage of the relevant intersections logged

§ The logging is of sufficient quality to support a Mineral Resource estimate and comprises a combination of quantitative and qualitative features. The entire hole is logged except any mud rotary pre-collars where this is not feasible.

§ Geological logging recorded qualitative descriptions of lithology, alteration, mineralisation, veining, and structure including orientation of key geological features where oriented core was available.

§ Geotechnical measurements were recorded in core including Rock Quality Designation (RQD), solid core recovery and qualitative rock strength measurements

§ Magnetic susceptibility measurements were recorded every metre using a KT20 machine

§ The bulk density of selected drill core intervals was determined at site on whole core samples

§ Digital data was recorded on site and stored in an SQL database

§ All drill cores were photographed, prior to cutting and sampling the core

§ The ground gravity survey data identified several gravity anomalies.  These have been modelled by an expert geophysical Consultant from NewExCo, and separately by Jim Hanneson from Adelaide Mining Geophysics Pty Ltd.

§ If core, whether cut or sawn and whether quarter, half or all core taken.

§ If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry

§ For all sample types, the nature, quality and appropriateness of the sample preparation technique

§ Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples

§ 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

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

§ Drill samples were freighted by road to the laboratory. All core is cut with a core saw, and half core sampled.

§ RC samples are split with a cone splitter attached to the cyclone and effort made to ensure samples are dry. Whether a specific sample is wet or dry is recorded in the database.

§ The samples are assayed at Intertek (Perth, WA).  Samples were dried at 105^oC, and the bulk of the samples pulverised (using LM5) to produce a pulped product. Oversize primary samples were crushed and a 3kg subsample then milled with the LM5 mill

§ Sub sampling is reduced to minimum by using total sample pulverisation prior to sub sampling wherever possible.

§ The sample sizes (2-3kg) are considered appropriate for the material being sampled

§ The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total

§ 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

§ Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established.

§ The samples were assayed for Au by a 50gm fire assay and for a multi-element scan using 4 acid digest and MS and OES finish for pathfinder and lithogeochemical elements. The assays are considered total rather than partial.

§ Greatland QA/QC procedures include using reference samples and field duplicate samples every 25 samples, in addition to the laboratories in - house QA/QC methods.

§ Analysis of the quality control sample assay results indicates that an acceptable level of accuracy and precision has been achieved and the database contains no analytical data that has been numerically manipulated.

§ Historical drilling- no sampling reported

§ The verification of significant intersections by either independent or alternative company personnel.

§ The use of twinned holes

§ Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols

§ Discuss any adjustment to assay data.

§ No twinned holes have been completed.

§ All data entry procedures, including original logging, sample depth selection for sampling and recording of sample numbers are recorded digitally in an electronic database.

§ There are no adjustments to assay data, other than below detection samples are reported at negative one half the detection limit

§ 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.

§ Specification of the grid system used.

§ Quality and adequacy of topographic control

§ Drill collar locations were surveyed using handheld GPS. RL's were collected with the same GPS and verified against regional SRTM datasets.

§ Drill rig alignment was attained primarily using a digital reflex TN-14 Azi Aligner, of if not available, compass and tape method.

§ Downhole survey was collected generally every 30m down the drill hole using a single shot Axis Mining Champ Gyro or Relfex North Seeking Gyro tool.

§ The topography is generally low relief to flat, elevation within the dune corridors in ranges between 250-265m AHD, steepening to the southeast.

§ All collar coordinates are provided in the Geocentric Datum of Australian (GDA2020 Zone 51). All relative depth information is reported in Australian Height Datum (AHD)

§ Data spacing for reporting of Exploration Results

§ 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

§ Whether sample compositing has been applied

§ RC drilling at Chilly is on 3 lines separated by approximately 750m and oriented at approximately 050 degrees to be at right angles to the observed geological strike. Hole spacing on lines was 100-200m with 2 holes on the northern line, 1 hole on the middle line and 2 holes on southern line.

§ Drill holes reported for the Havieron region are individual exploration holes targeting specific targets, and are not part of a grid pattern.

§ Not applicable in early-stage exploration

§ 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

§ 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

§ At Chilly, RC drilling is orientated nominally at 050^o true which is at right angles to the observed geological trend. Holes were angled at -60^o to provide a high angle to the expected vertical stratigraphy.

§ The Havieron region drilling is oriented at various angles to folded layering, and to identified sulphide mineralised structures. The relationship to possible mineralised structures is unknown at this stage.

§ Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings

§ The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area

The tenements are subject to Land Access Agreements with Jamukurnu-Yapalikurnu (JYAC) Aboriginal Corporation on behalf of the Martu People.

The Chilly RC drilling;

§  Occurred on tenement E45/4807 Strickland which is 100% owned by Rio Tinto Exploration Pty and is the subject of an agreement where Greatland is farming in (the Paterson South farm-in), but has not yet earned an interest.

§  Sits within the Martu category IV Indigenous Protection Area. Discussions with JYAC and the Martu state that there is allowance made for mining within Cat IV IPAs.

The Gravity survey at Atlantis occurs on tenement E45/4815 and is also subject to the Paterson South farm-in.

Diamond drilling on E45/5351 Skylar and E45/5532 Triangle South at the Bootstrap and Teague prospects respectively are subject to the Paterson South farm-in.

London diamond drilling occurs on E45/4701 - Scallywag which is 100% owned by Greatland Exploration Pty Ltd, a subsidiary of Greatland Holdings Group Pty Ltd.

All tenements are considered to be in good standing.

Regional 1km spaced AC drilling completed along existing tracks (TEA prefix) is unlikely to have been effective A84215

Scallywag E45/4701:

§ Historical work comprised shallow drilling in the north end of the Scallywag tenement (72 generally aircore holes, averaging 47.3m deep, 4 RAB holes (average 68m) and 9 RC holes (average 96.3m) by companies including Newcrest and Normandy Exploration Limited.

§ Historical reports (WAMEX "A" numbers) are referenced in previous RNS announcements dated 24 August 2021 and 16 April 2021 

§ Deposit type, geological setting and style of mineralisation

§ Exploration is for intrusion related and orogenic, structurally controlled Au-Cu deposits similar to Telfer, Havieron and Winu, all located in Neo-Proterozoic Yeneena Group sediments of the Paterson Province, Western Australia

§ 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

§ Greatland drill hole collar details are listed in - Table 1 for Chilly RC and Table 2 for Havieron Region drilling.

§ Anomalous results for Chilly RC are also recorded in Table 1

§ Assay results are not yet available for Havieron vicinity drilling.

§ 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

§ Anomalous results for Chilly RC are recorded in Table 1.  The anomalous sample intervals been selected as follows:

-  Au >=0.1ppm; or

-  Cu >=1000ppm; average grade,

with a maximum consecutive internal dilution of 4m. 

§ 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')

§ All Chilly RC intercepts reported are downhole and not true width. The intersected geology is interpreted to be subvertical with drilling angled at -60^o to provide a high angle to expected bedding parallel mineralisation. The nature of RC drilling is such that the true orientation of mineralisation intersected is currently unknown.

§ 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

§ Maps and a Section are provided in Figures 1-7. No significant discovery is reported

§ 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 reporting is considered balanced

§ Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; 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

§ No other substantive exploration data other than that provided in the figures

§ The nature and scale of planned further work (eg 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

§ Further drilling of the Chilly prospect has been proposed internally but has not advanced to a drill program, however the south eastern 3km extension of the magnetic linear in Figure 2 is considered prospective.

§ Four targets for follow up drilling are highlighted at Atlantis in Figure 6.

§ Further work at the Teague, London and Bootstrap prospects will be considered following the return and review of assays for those prospects.
