NEWS RELEASE | 13 December 2023

Results of Drilling and Ground Geophysical Survey at Scallywag

Greatland Gold plc (AIM:GGP) (Greatland or the Company) is pleased to announce the results of its 2023 drilling and geophysical exploration program at the 100% owned Scallywag tenement in the Paterson Region of Western Australia. Scallywag is located adjacent to Greatland's flagship Havieron gold-copper project.

Highlights

§ Anomalous gold and copper, and key pathfinder metal geochemistry, returned in assays from all four prospects.

§ A35 prospect returned best gold assay of 1m @ 0.83g/t Au from 238m in A35RD003 and peak copper intercept of 2m @ 0.17% Cu from 310m in A35RD002.

§ Preliminary modelling of the ground magneto-telluric (MT) data indicates a conductor at depth within a syncline fold structure along trend from Havieron.

§ Ongoing optimisation of the MT modelling is aimed at confirming the anomaly as a high priority target for 2024 as well as improving the understanding of stratigraphy and structure to identify Telfer style targets in the broader Scallywag tenement.

Greatland Managing Director, Shaun Day, commented:

"We are happy to report the effective completion of another phase of geological testing at our 100% owned Scallywag project, where drilling tested previously defined EM and geological targets, once again building on our understanding of the structure, stratigraphy and geochemistry of our landholding.

The ground magneto-telluric survey provides an enhanced understanding of the geology around the Scallywag syncline target area and identifies an untested conductor target coincident with a structural trap which potentially delineates the key structure to be tested."

2023 Exploration Program

A total of 10 diamond core holes were completed for 2,517.8m at the four high priority prospect targets areas of A35, A34, Pearl and Swan during the 2023 program (Table 1, Figure 2). Work in 2023 focused on completing the reverse circulation (RC) pre-collars with diamond core (DD) tails, targeting ground EM conductors (Figure 2), as reported in Greatland's previous RNS of 8 March 2023 titled "Scallywag Exploration Results". Downhole EM was attempted on each hole and successfully completed on five holes: A35RD003, PDD003, PDD005, PDD006 and PRD002. Results showed conductive responses at the weathering and stratigraphic boundaries, but no significant off-hole conductors.

A ground magneto-telluric survey was completed over the eastern part of the licence (Figure 3), to define any conductors under the deeper (>200m) cover of the major regional synclinal fold structure and area of previous drilling at Kraken, London and Blackbeard targets (see RNS of 20 January 2021 titled 'Initial Scallywag Drill Results and New Targets Identified').

Pearl Prospect

Drilling at Pearl intersected stratigraphy interpreted as the Telfer Member and Puntapunta. The Telfer Member is a mid to shallow marine sediment with minor carbonate units which is the host rock to The Telfer orebody.

PDD004 was drilled to twin an interval of high tenor metal fragments intersected from 77m downhole in PDD003 (see RNS of 8 March 2023 titled "Scallywag Exploration Results"), where poor drilling recoveries prevented interpretation of their significance. PDD004 returned weak gold anomalism of 2m @ 0.19g/t Au from 79m in the correlating position. The pathfinder geochemistry was not repeated, meaning the PDD003 anomaly may have been the result of downhole contamination.

Holes PRD002, PDD005 and PDD006 successfully targeted EM conductor plates from previous electromagnetic surveys.

Drilling intersected a sequence of massive, bedded, variably calcareous sediments; with minor zones of patchy K-feldspar / hematitic alteration, veining and faulting, providing some evidence of hydrothermal fluids and structural porosity. Anomalous pathfinder elements of copper, arsenic, lead, zinc and nickel, in addition to elevated bismuth, were recorded.

A34 and A35 Prospects

Diamond core tails at the A34 and A35 prospects successfully intersected the previously modelled electromagnetic plate conductors (Table 1). The A34 and A35 drill holes intersected progressively stronger calcareous units to the east. A35RD003 has a thick sequence of dolomite which has not been intersected in any previous Greatland drilling.

The best copper and gold results from the Scallywag drilling program occurred at the A35 prospect. They are 2m @ 0.17% copper from 310m in A35RD002 and 1m @ 0.83g/t gold from 238m in A35RD003. The copper interval from 310m correlates to a structurally disrupted zone at the contact between a strongly calcareous limestone unit and sandstones. It features weakly elevated bismuth, molybdenum, lead, sulphur and antimony, while the gold result was returned from strong calcareous and iron oxide weathered and faulted limestone sediments.

The A34 prospect returned limited assays of significance, with a minor zone of anomalous arsenic and bismuth, and a coincident anomalous cobalt assay (2m @ 11ppm bismuth and 2m @ 45ppm cobalt) and elevated molybdenum, sulphur and tellurium in an iron-oxidised, faulted coarse sandstone.

Swan Prospect

Swan drill hole SWRD004 to the north of the Pearl drill holes intersected Telfer Member sediments. SWRD005 further east intersected siliceous sediment but with increased calcareous units.

SWRD004 tested a zone of moderate carbonate - hematite - sericite alteration from 388 - 393m with minor quartz, carbonate, pyrite veining, coinciding with relatively anomalous gold, silver, arsenic, bismuth, cobalt, sulphur and tungsten. The highest copper intersection in the hole was recorded as 2m @ 0.04% copper from 391m, with coincident gold (peak 0.023g/t) and bismuth 2m @ 7.8g/t. These zones are indicative of mineralising fluids within a wider system.

The interval broadly coincident with the interpreted position of the EM conductor plate returned a gold assay of 0.22g/t Au from a 1m sample at 239m in SWRD005. It displayed a vuggy calcareous fault/vein zone, coincident with elevated metal pathfinder geochemistry of arsenic, chromium, molybdenum, nickel, lead, antimony, tungsten and zinc in a narrow 2-5m halo.

Ground Magneto-Telluric Survey

Greatland procured a ground magneto-telluric (MT) survey and modelling over the eastern part of the Scallywag tenement, comprising the major syncline structure that was the target of previous Greatland drilling at Kraken, London and Blackbeard (Figure 3). MT surveys are considered particularly effective in areas of deep conductive cover as the signal only traverses the conductive cover once, reducing the deleterious effect that this has at the receiver(s). A similar survey conducted in 2022 of the Havieron mining lease successfully detected the Havieron orebody.

The survey was designed to investigate the parts of the Scallywag project where thick (>200m) cover sequences exist which the aerial electromagnetic survey of 2021 did not effectively penetrate. Nominal station spacing was 500m over key geophysical targets. A total of 120 stations were collected.

Preliminary modelling appears to show a weak anomalous zone coincident with a de-magnetised section of the northern limb of the syncline. Further modelling is underway to improve identification of the geology under cover.

Ongoing optimisation of the MT modelling is aimed at confirming the anomaly as a high priority target for 2024 as well as improving the understanding of stratigraphy and structure to identify Telfer style targets in the broader Scallywag tenement.

Further work

The targeted electromagnetic plates were all successfully intersected, with generally very subtle petrophysical property changes or structural / mineralisation zones detected.

This round of drilling has provided a line of geological observations across the prospective Black Hills Anticline (Figure 2) after it plunges under cover to the south. The development of a two dimensional section across the anticline is in progress, which when combined with the final MT survey results will inform a broader three dimensional bedrock geology model of the Scallywag area including structure.

The objective of this work is to identify the prospective Telfer Member (which is not geophysically detectable) where it lies within structural traps under shallow to moderate cover. Any resultant blind Telfer-style ore body targets along with any confirmed MT conductors will be targeted for drilling.

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.

§ 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

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.

§ A single twin was completed (PDD004) to resample a zone of poor recovery intersected in PDD003. The twin hole intersected competent ground and week anomalism at the same depth as PDD003

§ 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

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 locations were surveyed using hand held GPS. RL's were collected with the same GPS

§ Drill rig alignment was attained using a hand held compass

§ Downhole survey orientation data was collected every 30m in diamond drill core segments of the drill hole using a single shot Axis Mining Champ Gyro

§ 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 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

§ Drill holes 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

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

Sample security

§ The measures taken to ensure sample security

§ The security of samples is controlled by tracking samples from drill rig to database

§ Entire core samples are delivered by company personnel to a freight company in Port Hedland for delivery by road freight to the assay lab in Perth, where the core is cut and sampled

Audits or reviews

§ The results of any audits or reviews of sampling techniques and data

§ No audits or reviews have been completed

Section 2 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 Scallywag tenement E45/4701 is 100% owned by Greatland Pty Ltd § The tenement is subject to a Land Access Agreement with Jamukurnu-Yapalikurnu Aboriginal Corporation
Exploration done by other parties	§ Acknowledgment and appraisal of exploration by other parties	§ 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
Geology	§ 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
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	§ Greatland drill hole collar details are listed in - Table 1 and anomalous results in Table 2
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 (Table 2) the samples have been selected as follows: - Au >0.1ppm; or - Cu >0.1%;
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
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 and a Section are provided in Figures 1-2. 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	§ Further drilling of any ground MT targets generated and follow up from further geological interpretation is planned for 2024, along with geophysical follow up.
