Havieron Exploration and Development Update

Greatland Gold plc (AIM:GGP), a mining development and exploration company with a focus on precious and base metals, is pleased to provide an update on the drilling campaign at the Havieron gold-copper project in the Paterson region of Western Australia. The Company notes the release of an ASX announcement titled "Exploration Update" by Newcrest Mining Ltd ("Newcrest") earlier today.

Activity to date and planned

§ The latest results comprise 24 new drill holes, including 20 holes from the Infill Drilling programme and 4 holes from the Growth Drilling programme

§ Significant mineralisation was reported in 19 of the new holes

§ The Havieron joint venture has now completed a total of 219,561m of drilling from 266 holes, with all the latest completed holes continuing to intersect mineralisation, and 19 reporting significant mineralisation

§ A further 10 drill holes have been completed and are awaiting assay

§ 90,000 meters of Growth Drilling targeted to 30 June 2022

Highlights of Drilling Campaign

§ Infill drilling within the South East Crescent Zone Inferred Mineral Resource supports the modelled grade and thickness within the South East Crescent Zone Mineral Resource:

§ The results support the continuity of the high grade South East Crescent Zone

§ This drilling is designed to infill the South East Crescent Inferred Mineral Resource volume to support the potential upgrade of a significant portion of the Inferred Mineral Resource to an Indicated Mineral Resource

§ Growth drilling continues to show potential for resource additions outside of the existing Inferred Mineral Resource, including a mineralised zone 100m below and 100m to the north-west of prior high grade holes:

§ Extension of the South East Crescent Zone at depth below the current Mineral Resource, where increasing mineralisation grade and thickness was observed from recent drilling

§ Further to results reported in the last period, HAD086W3 returned assays for the lower portion of the drill hole and reported a second high grade zone 200m below the existing resource of 48m @ 2.2g/t Au & 0.15% Cu from 1,525m, including 26.9m @ 3.7g/t Au & 0.26% Cu from 1,538.1m. A mineralised zone 100m below HAD086W3 was returned in HAD086W4, which confirmed extension of crescent mineralisation over 250m from the Inferred Mineral Resource extents. These results are approximately 100m to the north-west of prior high grade hole HAD133W1 and continue to support extensions of the Crescent Zone at depth. Drilling continues to assess the depth extents of the South East Crescent which now has a vertical extent of over 900m

§ Drilling to test geophysical targets outside of the known Havieron system have commenced at Havieron North, and Zipa

§ The Havieron North target is located 2 km north of Havieron and is sited on a magnetic high anomaly. Zipa, located approximately 1 km to the west of Havieron North and is centred on a prominent gravity high anomaly. The assay results for initial drilling into these targets is pending. Drilling continues to test these and other targets outboard of the main Havieron deposit

§ All drilling now focused on growth programs to continue into FY22 with 8 drill rigs operational, targeting:

§ Expansion of multiple higher-grade targets including Northern Breccia and North West Pod

§ Potential for additional North West trending structural corridors including the Eastern Breccia

§ South East Crescent and Breccia: Targeting potential resource definition of extensions below the existing resource shell and lateral extensions adjacent to the existing high-grade resource shell

§ New Targets: Identified outside of the immediate vicinity of the Havieron deposit, but within the Havieron Joint Venture area, with the potential to conduct drill testing of these targets in the future

§ Early Works advancing: Construction activities are progressing well with achievements including (as of 1 December 2021):

§ Box cut and portal completed in May 2021

§ Exploration decline has advanced 245 metres (as at 1 November 2021)

§ Decline contractor operating 24-hour per day

§ Planning has commenced for the first ventilation shaft, scheduled to begin in late December 2021

§ Works to progress the necessary approvals and permits required to commence the development of an operating underground mine and associated infrastructure at the Havieron Project are ongoing

§ Approval for blind boring of the decline vent raise from surface is in the final stages

§ Feasibility Study progressing: Feasibility study work by Newcrest continuing along with concurrent studies assessing broader growth options for Havieron. Upside opportunities are being evaluated to increase the scale and life of Havieron, as well as presenting the opportunity to adopt alternative, lower cost, mining methods. The Feasibility Study is still forecasted to be delivered in the December 2022 quarter.

Shaun Day, Chief Executive Officer of Greatland Gold plc, commented: "The drill programme at Havieron consistently delivers high grade results and intersects significant mineralisation which continues to support a significant upgrade of the Inferred Mineral Resource to an Indicated Mineral Resource.

"This latest drilling demonstrates continuity within the South East Crescent and together with significant assay intercepts running into the broader mineralized zonation. In addition, we have intercepts over 250 meters below the existing South East Crescent Mineral Resource which demonstrates the opportunity to further expand the ore body.

"As we head towards 2022, all drill programmes will be focused on growth, including new targets outside the known Havieron system with drill testing commencing at Havieron North and Zipa while we await the assay results of the initial drilling into these targets.

"With eight drill rigs operational, construction activities advancing and potential for significant upside for the scale and life of Havieron, there continues to be tremendous progress in the development of this world class project."

Further Information on Drilling and Operations at Havieron

The Havieron copper-gold deposit is centered on a deep magnetic anomaly located 45km east of Telfer in the Paterson Province, and where exploration drilling by Greatland during 2018 resulted in the discovery of gold and copper mineralisation under 420m of post mineralisation cover. The Joint Venture commenced drilling during the June 2019 quarter and has completed 219,561m of drilling from 266 drill holes to date (excluding holes in progress, abandoned holes, or drill holes which have not been sampled).

Drilling activities during the period of this report comprised 8,932m for 12 drill holes. Results from 24 holes (including 3 holes completed this period, and 21 holes from the September quarter) are reported here. Of these, 19 holes returned significant assay intercepts in excess of 50 gram metres Au (Au ppm x length metres).

Drilling in the reporting period was focused on potential resource growth at the South East Crescent, Northern Breccia and Eastern Breccia, and infill drilling the South East Crescent Zone to support the potential conversion of the Inferred Resource to Indicated Resource. Drilling included:

§ South East Crescent Zone Infill - assay results reported for twenty drill holes, and one hole awaiting assays.

§ South East Crescent Zone Growth - assay results reported for four drill holes, with one hole awaiting assays.

§ Northern Breccia & North West Pod - assay results awaiting for three drill holes.

§ Eastern Breccia - assay results awaiting for two drill holes.

§ First pass testing of geophysical targets outboard of the Havieron system (at Havieron North and Zipa) - assay results are awaiting for two drill holes.

Infill drilling within the South East Crescent Zone Inferred Mineral Resource was completed during the period, with 3 further drill holes completed, and assays reported for twenty drill holes (including 17 drill holes from the prior period). Assay results from one final drill hole is pending. This drilling is designed to infill the drill spacing within the South East Crescent Inferred Mineral Resource to 50m x 50m spacing to support the potential for a significant upgrade the Inferred Mineral Resource to an Indicated Mineral Resource. Results received from infill drilling support the modelled grade and thickness within the currently defined South East Crescent Zone Mineral Resource.

Results include:

§ HAD053W5

§ 119.7m @ 1.2g/t Au & 0.49% Cu from 1,041.4m

§ HAD053W6

§ 164.3m @ 1.8g/t Au & 0.53% Cu from 1,065m

§ including 14.3m @ 9.7g/t Au & 0.78% Cu from 1,065.7m

§ HAD061W1

§ 144.7m @ 1.6g/t Au & 0.14% Cu from 856.3m

§ including 14.2m @ 20g/t Au & 0.14% Cu from 1,035.8m

At the South East Crescent, growth drilling targeting higher grade mineralisation at depth on 75m by 75m spacing has extended the mineralisation 250m below the initial Inferred Mineral Resource estimate, with mineralisation still open below this. New results from four drill holes have been received.

Results include:

§ HAD086W3

§ 48m @ 2.2g/t Au & 0.15% Cu from 1,525m

§ including 26.9m @ 3.7g/t Au & 0.26% Cu from 1,538.1m

§ HAD086W4

§ 102.3m @ 1.5g/t Au & 0.17% Cu from 1,404.3m

§ including 62.8m @ 3.0g/t Au & 0.16% Cu from 1,460.5m

Other drilling completed during the period (but with assays awaited) included three drill holes testing the North Breccia and North West Pod Target (potential Crescent Sulphide Zone style mineralisation on the northern margin of the Northern Breccia) and two holes testing the Eastern Breccia.

Growth Drilling is ongoing, with eight rigs currently operational testing extensions of the South East Crescent Zone below 4,200mRL; extension and definition of the Northern and Eastern Breccias, and associated internal higher-grade zones within them to support potential expansion of the existing Inferred Mineral Resource; and drilling is continuing to target geophysical targets outboard of the main Havieron system.

Development Update

The development of the exploration decline continued during the period with 245 metres now complete as at 1 November 2021. Planning has commenced for the first ventilation shaft, scheduled to begin in late December 2021 and Approval for blind boring of the decline vent raise from surface is in the final stages. Works to progress the necessary approvals and permits that are required to commence the development of an operating underground mine and associated infrastructure at the Havieron Project are ongoing.

Background to Havieron and Joint Venture Agreement with Newcrest

The Havieron copper-gold project is operated by Newcrest under a Joint Venture Agreement with Greatland. As announced on 12 October 2021, following delivery of a Pre-Feasibility Study and meeting the Stage 4 expenditure, Newcrest is entitled to an additional 10% joint venture interest, resulting in an overall joint venture interest of 70% (Greatland 30%). Newcrest may acquire an additional 5% interest following completion of Stage 4 at fair market value.

The Joint Venture Agreement includes tolling principles reflecting the intention of the parties that, subject to a successful exploration programme and feasibility study and a positive decision to mine, the resulting joint venture mineralised material will be processed at Telfer, located 45km west of Havieron.

Notes for Editors:

Greatland Gold plc (AIM:GGP) is a mining development and exploration company with a focus on precious and base metals. The Company's flagship asset is the world-class Havieron gold-copper deposit in the Paterson region of Western Australia, discovered by Greatland and presently under development in Joint Venture with Newcrest Mining Ltd.

Havieron is located approximately 45km east of Newcrest's Telfer gold mine and, subject to positive decision to mine, will leverage the existing infrastructure and processing plant to significantly reduce the project's capital expenditure and carbon impact for a low-cost pathway to development. An extensive growth drilling programme is presently underway at Havieron with a maiden Pre-Feasibility Study released on the South-East crescent on 12 October 2021. Construction of the box cut and decline to develop the Havieron deposit commenced in February 2021.

Greatland has a proven track record of discovery and exploration success. It is pursuing the next generation of tier-one mineral deposits by applying advanced exploration techniques in under-explored regions. The Company is focused on safe, low-risk jurisdictions and is strategically positioned in the highly prospective Paterson region. Greatland has a total six projects across Australia with a focus on becoming a multi-commodity mining company of significant scale.

Sampling techniques

Core samples are obtained from core drilling in Proterozoic basement lithologies. PQ-HQ and NQ diameter core was drilled on a 6m run. Core was cut using an automated core-cutter and half core sampled at 1m intervals with breaks for major geological changes. Sampling intervals range from 0.2 - 1.0m. Cover sequences were not sampled.

Drilling techniques

Permian Paterson Formation cover sequence was drilled using mud rotary drilling. Depths of cover typically observed to approximately 420m vertically below surface. Steel casing was emplaced to secure the pre-collar.

Core drilling was advanced from the base of the cover sequence with PQ3, HQ3 and NQ2 diameter coring configuration.

Core from inclined drill holes are oriented on 3m and 6m runs using an electronic core orientation tool (Reflex ACTIII). At the end of each run, the bottom of hole position is marked by the driller, which is later transferred to the whole drill core run length with a bottom of hole reference line.

Drill sample recovery

Core recovery is systematically recorded from the commencement of coring to end of hole, by reconciling against driller's depth blocks in each core tray with data recorded in the database. Drillers depth blocks provided the depth, interval of core recovered, and interval of core drilled.

Core recoveries were typically 100%, with isolated zones of lower recovery.

Cover sequence drilling by the mud-rotary drilling did not yield recoverable samples.

Logging

Geological logging recorded qualitative descriptions of lithology, alteration, mineralisation, veining, and structure (for all core drilled 10,375m for 18 drill holes, all intersecting mineralisation), including orientation of key geological features.

Geotechnical measurements were recorded including Rock Quality Designation (RQD) fracture frequency, solid core recovery and qualitative rock strength measurements.

Magnetic susceptibility measurements were recorded every metre. The bulk density of selected drill core intervals was determined at site on whole core samples.

All geological and geotechnical logging was conducted at the Havieron site.

Digital data logging was captured on diamond drill core intervals only, and all data validated and stored in an acQuire database.

All drill cores were photographed, prior to cutting and/or sampling the core.

The logging is of sufficient quality to support Mineral Resource estimates.

Sub-sampling techniques and sample preparation

Sampling, sample preparation and quality control protocols are considered appropriate for the material being sampled.

Core was cut and sampled at the Telfer and Havieron core processing facility. Half core samples of between 0.2 and 2.0 m were collected in pre-numbered calico bags and grouped in plastic bags for dispatch to the laboratory. Sample weights typically varied from 0.5 to 8kg. Sample sizes are considered appropriate for the style of mineralisation. Drill core samples were freighted by air and road to the laboratory.

Sample preparation was conducted at the independent ISO17025 accredited Intertek Laboratory, Perth (Intertek). Samples were dried at 105oC, and crushed to 95% passing 4.75mm, and the split to obtain up to 3kg sub-sample, which was pulverised (using LM5) to produce a pulped product with the minimum standard of 95% passing 106μm. Routine grind size analysis is conducted. Duplicate samples were collected from crush and pulp samples at a rate of 1:20.

Duplicate results show an acceptable level of variability for the material sampled and style of mineralisation.

Periodic size checks (1:20) for crush and pulp samples and sample weights are provided by the laboratory and recorded in the acQuire database.

Quality of assay data and laboratory tests

Assaying of drill core samples was conducted at Intertek. All samples were assayed for 48 elements using a 4-acid digestion followed by ICP-AES/ICP-MS determination (method 4A/MS907), which is considered to provide a total assay for copper. Gold analyses were determined by 50g fire assay with AAS finish (method FA50N/AA), which is considered to provide a total assay for gold.

Sampling and assaying quality control procedures consisted of inclusion of certified reference material (CRMs), coarse residue and pulp duplicates with each batch (at least 1:20).

Assays of quality control samples were compared with reference samples in acQuire database and verified as acceptable prior to use of data from analysed batches.

Laboratory quality control data, including laboratory standards, blanks, duplicates, repeats and grind size results are captured in the acQuire database and assessed for accuracy and precision for recent data.

Extended quality control programmes including pulp samples submitted to an umpire laboratory and combined with more extensive re-submission programmes have been completed.

Analysis of the available 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.

The assaying techniques and quality control protocols used are considered appropriate for the data to be used for reporting exploration drilling results.

Verification of sampling and assaying

Sampling intervals defined by the geologist are electronically assigned sample identification numbers prior to core cutting. Corresponding sample numbers matching pre-labelled calico bags are assigned to each interval.

All sampling and assay information were stored in a secure acQuire database with restricted access.

Electronically generated sample submission forms providing the sample identification number accompany each submission to the laboratory. Assay results from the laboratory with corresponding sample identification are loaded directly into the acQuire database.

Assessment of reported significant assay intervals was verified by re-logging of diamond drill core intervals and assessment of high resolution core photography. The verification of significant intersections has been completed by Newcrest personnel and Newcrest's Competent Person/Qualified Person. John McIntyre, Greatland's Competent Person, has reviewed and validated the significant intersections.

No adjustments are made to assay data, and no twinned holes have been completed.

There are no currently known drilling, sampling, recovery, or other factors that could materially affect the accuracy or reliability of the data.

Location of data points

Drill collar locations were surveyed using a differential GPS with GNSS with a stated accuracy of +/- 0.5m for all drill holes reported.

Drill rig alignment was attained using an electronic azimuth aligner. Downhole survey was collected at 6-12m intervals in the cover sequence, and every 6 to 30m in diamond drill core segments of the drill hole using single shot (Axis Mining Champ Gyro). The single shot surveys have been validated using continuous survey to surface (Axis Mining Champ) along with a selection of drill holes re-surveyed by an external survey contactor using a DeviGyro tool - confirming sufficient accuracy for downhole spatial recording.

A LIDAR survey was completed over the project area in Nov 2019 which was used to prepare a DEM / topographic model for the project with a spatial accuracy of +/- 0.1m vertical and +/- 0.3m horizontal. The topography is generally low relief to flat, elevation within the dune corridors in ranges between 250-265m Australian Height Datum (AHD) steepening to the southeast. All collar coordinates are provided in the Geocentric Datum of Australian (GDA20 Zone 51). All relative depth information is reported in AHD +5000m.

Data spacing and distribution

Within the South-East Crescent and Breccia zone drill hole spacing ranges from 50 to 100m, to 50 by 50m within the initial resource extents. Outside the initial resource boundary drill hole spacing ranges from 50 to 200m in lateral extent within the breccia zone over an area of ~2km2. The data spacing is sufficient to establish the degree of geological and grade continuity.

Significant assay intercepts remain open. Further drilling is required to determine the extent of currently defined mineralisation. No sample compositing is applied to samples.

Drilling intersects mineralisation at various angles.

Orientation of data in relation to geological structure

Drill holes exploring the extents of the Havieron mineral system intersect moderately dipping carbonate and siliclastic sedimentary facies, mineralised breccia and sub-vertical intrusive lithologies. Geological modelling has been interpreted from historic and Newcrest drill holes.

Variable brecciation, alteration and sulphide mineralisation is observed with a footprint with dimensions of 650m x 350m trending in a north west orientation and over 1,000m in vertical extent below cover.

The subvertical southeast high grade arcuate Crescent Sulphide Zone has an average thickness of 20m and has been defined over a strike length of up to 550m, and over 850m in vertical extent below cover.

Drilling direction is oriented to intersect the steeply dipping high-grade sulphide mineralisation zones at an intersection angle of greater than 40 degrees. The drilled length of reported intersections is typically greater than true width of mineralisation.

Sample security

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

Drill core was delivered from the drill rig to the Havieron core yard every shift. On completion of geological and geotechnical logging, core processing was completed by Newcrest personnel at the Telfer facility but subsequently completed at the Havieron facility.

High resolution core photography and cutting of drill core was undertaken at the Havieron or Telfer core processing facilities.

Samples were freighted in sealed bags by air and road to the Laboratory, and in the custody of Newcrest representatives. Sample numbers are generated directly from the database. All samples are collected in pre-numbered calico bags.

Verification of sample numbers and identification is conducted by the laboratory on receipt of samples, and sample receipt advise issued to Newcrest.

Details of all sample movement are recorded in a database table. Dates, Hole ID sample ranges, and the analytical suite requested are recorded with the dispatch of samples to analytical services. Any discrepancies logged at the receipt of samples into the analytical services are validated.

Audits or reviews

Internal reviews of core handling, sample preparation and assays laboratories were conducted on a regular basis by both project personnel and owner representatives.

In the Competent Person's opinion, the sample preparation, security and analytical procedures are consistent with current industry standards and are entirely appropriate and acceptable for the styles of mineralisation identified and will be appropriate for use in the reporting of exploration results and Mineral Resource estimates. There are no identified drilling, sampling or recovery factors that materially impact the adequacy and reliability of the results of the drilling programme in place at the Havieron Project.

Criteria

Commentary

Mineral tenement and land tenure status

The Havieron Project is entirely contained within mining tenement M45/1287, which is jointly owned by Greatland Pty Ltd and Newcrest Operations Limited. Newcrest has entered into a Joint Venture Agreement (effective 30 November 2020) and Farm-In Agreement (effective 12 March 2019) with Greatland Pty Ltd and Greatland Gold plc. Newcrest is the manager of the Havieron Project. The Havieron copper-gold project is operated by Newcrest under a Joint Venture Agreement with Greatland. As announced on 12 October 2021, following delivery of a Pre-Feasibility Study and meeting the Stage 4 expenditure, Newcrest is entitled to an additional 10% joint venture interest, resulting in an overall joint venture interest of 70% (Greatland 30%). Newcrest may acquire an additional 5% interest following completion of Stage 4 at fair market value.

Newcrest and the Western Desert Lands Aboriginal Corporation are parties to an Indigenous Land Use Agreement (ILUA) which relates to the use of native title land for Newcrest's current operations at Telfer and its activities within a 60-km radius around Telfer and includes its exploration activities at Havieron. The parties have agreed that the ILUA will apply to any future development activities by the Joint Venture Participants (Newcrest and Greatland Gold) at Havieron.

Exploration done by other parties

Newcrest completed six core holes in the vicinity of the Havieron Project from 1991 to 2003. Greatland Gold completed drill targeting and drilling of nine Reverse Circulation (RC) drill holes with core tails for a total of approximately 6,800m in 2018. Results of drilling programmes conducted by Greatland Gold have previously been reported on the Greatland Gold website.

Drilling has defined an intrusion-related mineral system with evidence of breccia and massive sulphide-hosted higher-grade gold-copper mineralisation.

Geology

The Havieron Project is located within the north-western exposure of the Palaeo-Proterozoic to Neoproterozoic Paterson Orogen (formerly Paterson Province), 45 km east of Telfer. The Yeneena Supergroup hosts the Havieron prospect and consists of a 9km thick sequence of marine sedimentary rocks and is entirely overlain by approximately 420m of Phanerozoic sediments of the Paterson Formation and Quaternary aeolian sediments.

Gold and copper mineralisation at Havieron consist of breccia, vein and massive sulphide replacement gold and copper mineralisation typical of intrusion-related and skarn styles of mineralisation. Mineralisation is hosted by metasedimentary rocks (meta-sandstones, meta-siltstones and meta-carbonate) and intrusive rocks of an undetermined age. The main mineral assemblage contains well developed pyrrhotite-chalcopyrite and pyrite sulphide mineral assemblages as breccia and vein infill, and massive sulphide lenses. The main mineralisation event is associated with amphibole-carbonate-biotite-sericite-chlorite wall rock alteration. Drilling has partially defined the extents of mineralisation which are observed over 650m by 350m within an arcuate shaped mineralised zone, and to depths of up to 1400m below surface.

Drill hole Information

As provided in Appendix II.

Data aggregation methods

Significant assay intercepts are reported as (A) length-weighted averages exceeding 1.0g/t Au greater than or equal to 10m, with a maximum of 5m consecutive internal dilution; and (B) length-weighted averages exceeding 0.2g/t Au for greater than or equal to 20m, with a maximum of 10m consecutive internal dilution, and (C) intervals of >30g/t with no internal dilution which are greater or equal to 30 gram metres (Au_ppm x length). No top cuts are applied to intercept calculations.

Relationship between mineralisation widths and intercept lengths

Significant assay intervals reported represent apparent widths. Drilling is not always perpendicular to the dip of mineralisation and true widths are less than downhole widths. Estimates of true widths will only be possible when all results are received, and final geological interpretations have been completed.
