NEWS RELEASE | 14 November 2023
Drilling commences at 100% owned Ernest Giles Project
Co-funded diamond core drilling to test the high priority Meadows gold prospect
Greatland Gold plc (AIM:GGP) (Greatland or the Company) is pleased to advise that drilling has commenced at the Meadows gold prospect within the Ernest Giles Project (Ernest Giles).
Highlights
§ Ernest Giles is an underexplored Archean greenstone belt which lies within the highly mineralised Yilgarn Craton of Western Australia
§ A drill rig is on site and has commenced diamond core drilling at the highly prospective Meadows gold prospect
§ Heritage surveys and mobilisation was completed safely and quickly following entry into the Ernest Giles Land Access Agreement (LAA) in September 2023
§ First two diamond holes will test interpreted mineralised zones and are co-funded by the Government of Western Australia's Exploration Incentive Scheme (EIS) drilling grant for up to A$220,000 (£115,000)
§ Current drilling builds on previous work at Ernest Giles and will provide important geological and structural information to inform a systematic reverse circulation drill program in 2024
Greatland Managing Director, Shaun Day, commented:
"We are very pleased to be drilling the high priority Meadows gold prospect at Ernest Giles following conclusion of the Land Access Agreement."
"Ernest Giles sits within an underexplored greenstone belt located north of the world-class Tropicana and Gruyere gold operations. As a 100% owned project, Ernest Giles represents an excellent exploration opportunity for Greatland and our shareholders."
Overview of the Ernest Giles Project
The Ernest Giles Project is located approximately 250km north-east of the town of Laverton and covers a folded belt of magnetic greenstone rocks (Figure 1) which is typical of the highly gold and nickel endowed parts of the Archean Goldfields of Western Australia. The Goldfields host large gold camps such as Kalgoorlie, St Ives, Leonora, Laverton, Mt Magnet, Jundee, Gruyere and Tropicana. The prospective greenstone sequence at Ernest Giles does not outcrop and is therefore underexplored relative to the remainder of the Goldfields.
Greatland's granted and under-application tenure at Ernest Giles comprises a comprehensive holding over what Greatland considers to be the most prospective near surface portions of the Ernest Giles belt, covering more than 1,950km2.

Current drilling program
Previous exploration at Ernest Giles included a program of 62,800m spaced vertical RC drillholes, largely focused on the Meadows prospect, in addition to airborne magnetics and ground gravity surveys.
Gold mineralisation and anomalism is hosted within altered mafic volcanic, banded iron formation (BIF) and syenite. The mafic is pyrite and albite altered with thin quartz veinlets. Hematite alteration has also been observed. The syenite comprises disseminated pyrite and may be hematite altered.
Results returned previously included a peak of 16m @ 0.36g/t Au from 182m downhole including 3m @ 1.28g/t Au in hole ERC011. Table 1 in Appendix 1 sets out all significant results.
The two EIS co-funded diamond core drill holes will provide the first angled diamond holes and oriented core at Meadows, considered critical for the geological understanding of the project.
Drill hole EG_Prop_1 targets two mineralised zones within the previous vertical RC hole ERC011 which returned values +1g/t Au (Appendix 1, Table 1) in mafic rock (Figure 4).
Drill hole EG_Prop_2 targets the interpreted syenite (intrusive granitoid) body intersected in ERC014 which returned 18m @ 0.11g/t Au (Appendix 1, Table 1).
In addition, the drilling is planned to:
§ confirm gold mineralisation and anomalism intersected in previous RC drilling and test for continuity down dip;
§ provide geological and structural information to understand the setting and nature of gold mineralisation;
§ investigate a larger section across strike than has been possible with vertical drillholes;
§ identify pathfinders for mineralisation; and
§ be utilised as a platform for downhole geophysics should it be viable.

Further work
Additional ongoing work will include airborne geophysics to better understand the geology of the entire Ernest Giles belt. A follow up RC drilling program will be designed utilising the knowledge gained from the current drilling, to systematically target the best results of all drilling at Meadows to date. This work will commence in the 2024 calendar year.

About Greatland
Greatland is a mining development and exploration company focused primarily on precious and base metals.
The Company's flagship asset is the world-class Havieron gold-copper project in the Paterson Province of Western Australia, discovered by Greatland and presently under development in joint venture with world gold major, Newmont Corporation.
Havieron is located approximately 45km east of Newmont's existing Telfer gold mine. The box cut and decline to the Havieron orebody commenced in February 2021. Total development now exceeds 2,820m including over 2,030m of advance in the main access decline (as at 8 October 2023). Subject to a positive feasibility study and Decision to Mine, Havieron is intended to leverage the existing Telfer infrastructure and processing plant. Access to Telfer will de-risk the development and reduces capital expenditure.
Greatland has a proven track record of discovery and exploration success and is pursuing the next generation of tier-one mineral deposits by applying advanced exploration techniques in under-explored regions. Greatland has a number of exploration projects across Western Australia and in parallel to the development of Havieron is focused on becoming a multi-commodity miner of significant scale.

Appendix 2: JORC Table 1
Section 1 Ernest Giles Project: Sampling Techniques and Data
Criteria | JORC Code Explanation | Commentary |
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) § 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 | § Reverse Circulation (RC) Drilling and RC pre-collars for diamond - 1m samples were collected from the cyclone and a hollow "spear" was used to collect a sample for assay. The residue was placed in individual piles on the ground. - The samples were then composited over 4m and were collected for the entire length of the drillhole including cover. An approximate 3kg sample was pulverised to provide a 50g charge for fire assay for gold and 25g charges for 47 element geochemistry analysis. § Diamond drilling - Where diamond commenced in Proterozoic cover and in areas considered of low interest in the bedrock in early holes, a 20cm long piece of half core was sampled every 4 metres. - In archean basement areas of interest in early drilling and for the whole basement in later drilling, half core was sampled on a single metre basis. - The entire sample was crushed and pulverized to provide a 50g charge for fire assay for gold and 25g charges for 47 element geochemistry analysis. MMI soil sampling - Samples were collected from a depth of 300mmm and sieved to -2mm and sent for MMI analysis for a suite of 53 elements. - Target elements are extracted using weak solutions of organic and inorganic compounds rather than conventional aggressive acid or cyanide-based digest for a partial extraction of minerals adhered to the boundary of grains in an effort to identify transported metals using ICP-MS. Passive seismic was carried out over the Meadows target area. A total of 184 readings were taken over five east-west lines and were used for calibration of the interface depths to estimate the regolith-basement interface.
Ground Gravity was undertaken in the Meadows, Wishbone and Empress target areas at a sample spacing of 1600m x 200m for a total of 360 line km
|
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) | § RC - A single purpose RC drill rig was used to complete vertical holes. - No information is available as to whether a face sampling hammer was used, but it is assumed. § Diamond drilling - A multipurpose drilling rig was used to complete vertical holes. - Holes were pre-collared with RC to bedrock (approximately 100-150m), then completed with diamond core to between 300 and 380m. - No information is available on core diameter or tube type. A combination of HQ and NQ with standard (not triple) tube is assumed. - As holes are vertical no orientation of cure was possible.
|
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 | § 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. § No relationship between recovery and grade has been observed.
|
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 § The total length and percentage of the relevant intersections logged | § The logging comprises a combination of quantitative and qualitative features. The entire hole is logged. § Geological logging recorded qualitative descriptions of lithology, alteration, mineralisation, veining, and structure of key geological features. § Digital data was recorded on site and stored in an SQL database. § The ground EM survey data was interpreted and reported by expert geophysical Consultants NewExCo. |
Sub-sampling techniques and sample preparation | § 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 | § All samples were freighted by road to the laboratory. § All core is cut with a core saw, and half core samples sent to the laboratory. § All drill samples were sent to Genalysis Laboratories in Kalgoorlie and analysed for a suite of 47 elements. § RC composite samples showing anomalous gold levels were then resampled at 1m sample intervals with the same technique as the composites. § The sample sizes (0.5-3kg) are considered appropriate for the material being sampled. § MMI samples were sent to SGS Laboratories in Perth and analysed for a suite of 53 elements. |
Quality of assay data and laboratory tests | § 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 drill samples were assayed for Au by a 50gm fire assay and 25g 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. § Blanks were inserted roughly every 25 samples in diamond core. 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 include duplicates , standard and blank assays for each batch. § Analysis of the quality control sample assay results indicates that an acceptable level of accuracy and precision has been achieved. § Comparison of the original laboratory files and the database plus database logs indicates no analytical data has been numerically manipulated.
|
Verification of sampling and assaying | § 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. MMI Results correlated favourably with pre-existing drilling and with a trial of Newcrest's proprietary Deep Sensing Geochemistry (DSG) sampling.
|
Location of data points | § 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 and surface sample locations were surveyed using hand held GPS. RL's were collected with the same GPS § As all holes were drilled vertically drill rig alignment was not required. § Downhole survey was collected using a single shot reflex down hole camera for diamond holes at 90 metres, then base of transported and every fifty metres in bedrock. No downhole surveys were taken for RC holes § The topography is generally low relief to flat, elevation within the dune corridors in ranges between 250-265m AHD steepening to the southeast § All coordinates are provided in the Geocentric Datum of Australian (GDA94 Zone 51). All relative depth information is reported in Australian Height Datum (AHD) |
Data spacing and distribution | § 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 holes were vertical and drilled on a broad grid spacing of 1,600m x 800m. The broad spaced holes were designed to test basement lithologies for gold mineralisation which had been intersected in previous 'wildcat' drilling by the company, and also test geochemical responses from surface sampling work carried out by a previous explorer. § RC samples including RC pre-collars were original composited to 4m. any anomalous intervals where then re-assayed on 1m intervals. Diamond drilling was carried out on a "wild cat " basis with individual holes testing geochemical and geophysical anomalies
The drill data spacing is not sufficient for calculation of a mineral resource or reserve and none is reported.
MMI sampling was done on 200m x800m basis with the shorter distance across strike. |
Orientation of data in relation to geological structure | § 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 | § Drilling is vertical into what are expected to be dominantly vertical stratigraphy. Any mineralisation intervals are expected to be significantly greater than true width.
|
Sample security | § The measures taken to ensure sample security | § The security of samples is controlled by tracking samples from drill rig to database. § |
Audits or reviews | § The results of any audits or reviews of sampling techniques and data | § No audits or reviews have been completed |
Section 2 Ernest Giles Project: Reporting of Exploration Results
Criteria | JORC Code explanation | Commentary |
Mineral tenement and land tenure status | 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 Ernest Giles tenements E38/3185 and E38/2205 are 100% owned by Greatland Pty Ltd Land Access Agreements are currently being negotiated with the native title holders and claimants for all granted tenement and applications. No access has currently been approved.

Exploration done by other parties | Acknowledgment and appraisal of exploration by other parties | CRA initially carried out an aeromagnetic survey in the mid 90's. WMC after reviewing the geophysics interpreted the area as containing archean greenstones, and completed regional soils and gravity surveys along with 200m spaced aeromagnetic and 8 RC holes (ENGC01-8) over what is now the Meadows prospect, identifying anomalous gold between 1996 and 1999. MRG metal completed further aeromagnetics and 3 diamond holes (EY4001-EY4003) in the region from 2011 to 2015. |
Geology | Deposit type, geological setting and style of mineralisation | Exploration is for Yilgarn style Archean lode gold. |
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 | Drill hole collar details are listed in Appendix 1 (Table 2) and anomalous results in Appendix 1 (Table 1).
|
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 | No economically significant results have been reported, and no data aggregation methods have been applied. Where anomalous results are quoted (Appendix 1, Table 1) the samples have been selected as follows: Au >0.1ppm or Au >0.5ppm for higher grade with a maximum consecutive internal waste of 5m
|
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') | No economically significant results are reported, and there is no known relationship between reported widths and the geometry of any mineralisation. All intercepts are reported downhole as 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 | Maps are provided in Figures 1 - 3. No significant discovery is reported. |
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 reporting is considered balanced. |
Other substantive exploration data | 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. |
Further work | 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 | Finalization of land access agreement is required prior to further on ground work. Systematic .infill of anomalous RC and diamond drilling is planned for the Meadows prospect. |
