Excellent Growth Drilling results continue to support potential for resource expansion with additional mineralisation identified in Northern and Eastern Breccias
Several exciting results from the South East Crescent, extending the high grade mineralisation beneath the initial Inferred Resource estimate
Early works progressing with the Karlajartu decline officially opened and advanced to 69m from Portal
Greatland Gold plc (AIM:GGP), the precious and base metals mining and exploration company and Joint Venture owner of the world class Havieron gold-copper project, 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 "Quarterly Exploration Report" by Newcrest Mining Ltd ("Newcrest") earlier today.
Drilling activities since the last update include new results from the Growth Drilling programme, which continue to support the potential for resource expansion of the Havieron gold-copper project.
The latest results comprise seven new drill holes from the Growth Drilling programme (not previously reported), with all holes intersecting significant mineralisation. Newcrest has now completed a total of 184,081m of drilling from 212 holes to date, with all the latest holes continuing to intersect significant mineralisation.
Highlights
§ Further significant results from Growth Drilling continue to support the potential for resource expansion within the Havieron gold-copper mineralised system
o Growth Drilling continues to confirm extensions to the high grade South East Crescent and the Northern Breccia mineralisation below and around the initial Inferred Mineral Resource estimate.
o HAD138 (Northern Breccia) reported 84.5m @ 2.0 g/t Au & 0.05 % Cu from 683m, Including 12.7m @ 6.0 g/t Au & 0.01 % Cu from 685.3m.
§ 2021 Growth Drilling is progressing into FY22
o A further 15 Growth drill holes have been completed with samples awaiting assay, anticipated to be received and reported in the next update.
o These holes are part of the ongoing Growth Drilling programme, targeting:
§ North West Crescent and Northern Breccia: Zone of initial focus aimed at providing support for the potential expansion of the existing Inferred Mineral Resource.
§ Eastern Breccia: Drill testing and interpretation of the geological and mineralisation controls is ongoing.
§ 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 14 July 2021):
o Box cut and portal completed in May 2021
o Exploration decline commenced on 14 May 2021 and has advanced 69 metres
o Decline contractor has moved to 24-hour operations
o All surface support infrastructure is nearing completion

Shaun Day, Chief Executive Officer of Greatland Gold plc, commented: "There is a tremendous amount of activity and excitement with the progress across the Havieron gold-copper project. In addition to the intensity of the drilling programme, the decline development is now maintaining 24-hour operations and the surface support infrastructure is nearing completion."
"The drilling programme keeps on delivering with every hole continuing to hit significant mineralisation while also growing the scale of the Project. Drilling has identified several exciting results from the South East Crescent, extending the high grade mineralisation beneath the initial Inferred Resource estimate."
"The ongoing success from each set of drill results builds confidence in the world class nature of the Havieron gold-copper project and its potential to expand. This de-risks the project as we progress it towards potential production and adds further upside to the value of the deposit."
"With 15 intersections awaiting assay, the volume of information available is expected to significantly expand with our next update as we continue to grow our understanding and scale of the Havieron gold-copper project."
Results from the seven Growth Drilling holes reported in the last update ("Further Excellent Growth Drilling Results at Havieron", dated 10 June 2021) and reported in Newcrest's Quarterly Exploration Report are also included below.
Analytical results for new drilling from HAD057W6, HAD089W2, HAD097W4, HAD099, HAD099W1, HAD136W1 and HAD138 (partial results) have been received and are announced today, along with results from HAD086W1, HAD089W1, HAD096W1, HAD097W3, HAD106W2, HAD133, and HAD136 which were completed early in the Quarter and have been previously reported.

Further Information on Newcrest Drilling and Operations at Havieron
Exploration activities at Havieron are operated by Newcrest under a Joint Venture Agreement with Greatland. The Havieron deposit is centered on a magnetic anomaly located 45km east of Telfer. Exploration drilling by Greatland during 2018 resulted in the discovery of gold and copper mineralisation under 420m of post mineralisation cover. Newcrest commenced drilling at Havieron during the June 2019 quarter and have completed 184,081m of drilling from 212 holes to date (excluding holes in progress, abandoned holes, or drill holes which have not been sampled).
Drilling activities from 29 drill holes resulted in 25,418m of drilling completed since 31 March 2021. Results from 14 of 29 holes drilled have been received, with 9 holes returning significant assay intercepts in excess of 100 gram metres Au (Au_ppm x length).
Drilling activity during the period utilised up to eight drill rigs, and the results reported today include seven new drill holes (completed since the last release dated 10 June 2021). A further 15 holes have been completed but with assay results pending. Results from the seven "Growth Drilling" holes reported in the last update ("Further Excellent Growth Drilling Results at Havieron", dated 10 June 2021) and reported in Newcrest' Quarterly are also included below. All drilling reported here is from Growth Drilling with a focus on the North West Crescent, Northern Breccia Zone, depth extensions of the South East Crescent and Breccia, and drilling to test the extents of the Eastern Breccia.
Significant new results are presented in Table 1, and full drilling results are presented in Appendix II. Drilling in the reporting period was designed to support potential resource growth at the South East Crescent, Northern Breccia, and Havieron system extents and Eastern Breccia including:
· South East Crescent Zone - four drill holes completed, with assay results reported for two drill holes
· Northern Breccia - 21 drill holes completed, with assay results reported for 12 drill holes
· Eastern Breccia - four drill holes completed, all assays pending
At the South East Crescent, four drill holes targeting resource extensions on 75m x 75m spacing for up to 200m below the initial Inferred Mineral Resource extents have been completed. Results from two drill holes have been received, with previously reported holes HAD086W1^^ and HAD133^^ extending the high-grade mineralisation ~80m below the base of the Inferred Mineral Resource estimate. These intercepts are also below previously reported hole HAD065W2^^ (120.7m @ 9.3 g/t Au & 0.18 % Cu from 1,349.3m, including 26.6m @ 34 g/t Au & 0.23 % Cu from 1,384.4m). Assay results from two further drill holes HAD133W1 and HAD133W2 are pending. Further drilling is planned to continue to assess the lower RL resource extensions of the South East Crescent zone.
Results from HAD086W1 and HAD133 include:
· HAD086W1^^
o 99.7m @ 2.5g/t Au & 0.85% Cu from 1,308m
o including 50.4m @ 4.3g/t Au & 1.6% Cu from 1,313.6m
· HAD133^^
o 85m @ 11g/t Au & 0.29% Cu from 1,345m
o including 13m @ 32g/t Au & 0.46% Cu from 1,363m
o including 14.5m @ 32g/t Au & 0.33% Cu from 1,396.5m
Three further drill holes drilled to test lower target positions in the Northern Breccia traversed the South East Crescent Zone, within the current Inferred Mineral Resource footprint including HAD097W3^^, HAD097W4 and HAD136^^. Results demonstrate good alignment with modelled grade and thickness within the South East Crescent zone which further supports the geological model including continuity of high grade.
Results include:
· HAD097W3^^
o 47.8m @ 2.3g/t Au & 0.28% Cu from 620.2m
o including 28.3m @ 3.8g/t Au & 0.45% Cu from 639.7m
· HAD097W4
o 50m @ 1.1 g/t Au & 0.04 % Cu from 1,051m
o including 10m @ 2.0 g/t Au & 0.04 % Cu from 1,081m
· HAD136^^
o 55.2m @ 2.5g/t Au & 0.65% Cu from 501m
o including 24.5m @ 5.4g/t Au & 0.95% Cu from 506.8m
At the Northern Breccia, 21 drill holes have been completed, with results from 12 drill holes reported. Drilling has targeted the Northern Breccia mineralisation footprint on a 75m x 75m target spacing to allow for a full assessment of the potential resource footprint in this zone (previously limited by drill spacing). Drilling has extended the mineralised breccia footprint around the Inferred Mineral Resource extents with reported drill holes supporting extensions to breccia mineralisation. Drilling has confirmed and increased the continuity of mineralisation as a north-west mineralised corridor which has been identified up to 300m in length, and 100m wide, between 4300 - 4100mRL and remains open at depth. Higher grade mineralisation has been identified internal to the mineralised breccia corridor. The results support the potential for incremental resource extensions.
Results include:
· HAD057W6
o 25.1 m @ 2.3g/t Au & 0.03% Cu from 1,123.4m
o including 13.4m @ 4.0g/t Au & 0.06% Cu from 1,127.5m
· HAD089W1^^
o 81.3m @ 1.2g/t Au & 0.04% Cu from 1,009.7m
· HAD136W1
o 36.2m @ 2.7 g/t Au & 0.09 % Cu from 988.8m
o 201m @ 0.45 g/t Au and 0.09% Cu from 1050m
· HAD138
o 84.5m @ 2.0 g/t Au & 0.05 % Cu from 683m
o Including 12.7m @ 6.0 g/t Au & 0.01 % Cu from 685.3m
At the Eastern Breccia four drill holes have been completed, with results from all drill holes pending. Drilling has targeted along strike from prior reported drill holes HAD083 (184.7m @ 1.8 g/t Au and 0.18% Cu from 1098m; and 134m @ 1.4 g/t Au and 0.04% Cu from 1529m) and HAD084 (342.2m @ 2.0 g/t Au and 0.11% Cu from 1536.8m), over a strike length of approximately 600m. Drill testing and interpretation of the geological and mineralisation controls of the Eastern Breccia Zone is ongoing.
All drill rigs are currently operational on the growth drilling programme, including testing extensions of the South East Crescent Zone below 4,200mRL, extension and definition of the Northern Breccia and associated internal higher-grade zones to support potential expansion of the existing Inferred Mineral Resource. Additionally, drilling programmes are focussed on defining the system footprint of the Havieron deposit, including Eastern Breccia.
Drilling since May 2019 has outlined an ovoid shaped zone of variable brecciation, alteration and sulphide mineralisation with dimensions of 650m x 350m trending in a north west orientation. Breccia mineralisation has been identified internally and externally to the Crescent zones, including targets which remain open to the east, northwest and southeast. Mineralisation has been observed to greater than 1,000m in vertical extent below the around 420m thick post mineral cover sequence and remains open at depth. Within this ovoid shaped zone (at this stage) exploration has identified four key target regions, which are:
§ South East Crescent and Breccia
§ North West Crescent
§ Northern Breccia; and
§ Eastern Breccia
Drill data density in the South East Crescent and adjacent Breccia and a portion of the Northern Breccia has been sufficient for the definition of an Inferred Mineral Resource Estimate1 for these domains. Reported inside an A$50/t Net Smelter Return ("NSR") shell, the volume of identified mineralised geological domains where information to estimate the metal inventory and grades is at a sufficient magnitude and having the reasonable prospects of eventual economic extraction comprises:
§ 52Mt @ 2.0g/t Au and 0.31% Cu for 3.4Moz Au and 160Kt Cu for 4.2Moz gold equivalent2, included in geological domains:
o Crescent Zone containing 18Mt @ 3.8g/t Au and 0.61% Cu for 2.2Moz Au and 110Kt Cu; and
o Breccia Zone containing 34Mt @ 1.1g/t Au and 0.15% Cu for 1.2Moz Au and 50Kt Cu.
[1] Refer to Newcrest announcement titled "Newcrest announces initial Inferred Mineral Resource estimate for Havieron of 3.4Moz of gold and 160Kt of Copper" dated 10 December 2020 and available on www.asx.com.au under the code "NCM".
2 The gold equivalent (AuEq) is based on assumed prices of US$1,400/oz Au and US$3.40/lb Cu, gold recoveries of 94% (Crescent) and 84% (Breccia), and copper recoveries of 84% (Crescent) and 82% (Breccia), which equates to a formula of approximately AuEq = Au (g/t) + 1.65 * Cu (%). In Greatland's opinion all elements (gold and copper) have a reasonable potential to be recovered and sold
Mineralisation in the Havieron deposit is hosted by metasedimentary (meta-sandstones, meta-siltstones and meta-carbonate) and intrusive rocks. Gold and copper mineralisation is hosted in breccia, vein and massive sulphide replacement styles, typical of intrusion-related and skarn types of mineralisation. The main sulphide mineral assemblage contains well developed pyrrhotite-chalcopyrite and pyrite. Alteration assemblages associated with mineralisation are amphibole-carbonate-biotite-sericite-chlorite. Higher-grade gold zones (+10g/t Au) are often associated with quartz/chalcopyrite-pyrite veining.
Outside of the Initial Inferred Mineral Resource Estimate, mineralisation remains open with encouraging results identified from below the South East Crescent and Breccia Zone, and around the Northern Breccia Zone (including the new results reported here), and the Eastern Breccia Zone. The extents of the Havieron system are still to be defined.
Currently, all drill rigs are operational on the Growth Drilling programme with a focus on the North West Crescent, Northern Breccia Zone and depth extension of the South East Crescent and Breccia. This drilling is aimed to provide support for the potential expansion of the existing Inferred Mineral Resource estimate. Drill testing and interpretation of the geological and mineralisation controls of the Eastern Breccia Zone is ongoing.
Further targets outside of Havieron, but within the Havieron Joint Venture area, have been identified with the potential to conduct drilling to test these targets in the future.
Construction update
Newcrest received the required regulatory approvals to commence construction of an exploration decline at Havieron following approval of the Water Management Plan on 30 April 2021.
Construction activities are progressing to plan with achievements as at 14 July 2021 including:
· Box cut and portal completed in May 2021
· Exploration decline commenced on 14 May 2021 and has advanced 69 metres
· Decline contractor has moved to 24 hour operations
· All surface support infrastructure is nearing completion
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 Project are ongoing1.
The Havieron Pre-Feasibility Study in expected to be released in the second half of CY21.
Additional drill hole information is presented in Appendix I and tabulated drill hole intercepts are presented in Appendix II. A 3D schematic plan view of Crescent Sulphide Zone and Breccia target zones is shown in Figure 1, a schematic horizontal slice through the Crescent Sulphide Zone and Breccia hosted mineralisation is shown in Figure 2, drill hole locations are shown in Figure 3 and Cross Sections are shown in Figures 4 and 5.
[1]The development of any underground mine at the Havieron Project will also be subject to the completion of a successful exploration programme and further studies, market and operating conditions, Board approvals, and a positive decision to mine.
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 30 November 2020, Newcrest has now met the Stage 3 expenditure requirement (US$45 million) and is entitled to earn an additional 20% joint venture interest, resulting in an overall joint venture interest of 60% (Greatland 40%). Newcrest can earn up to a 70% joint venture interest through total expenditure of US$65 million and the completion of a series of exploration and development milestones in a four-stage farm-in over a six-year period that commenced in March 2019. 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.
Juri Joint Venture
On 30 November 2020, Newcrest announced its entry into the Juri Joint Venture. Juri is a farm-in and joint venture agreement with Greatland Gold with respect to its Black Hills and Paterson Range East projects, located within the Paterson Province approximately 50km from the Telfer operation. The joint venture covers an area of approximately 248km2.
Under the terms of the agreement, Newcrest has been granted an initial 25% joint venture interest with the potential to earn up to a 75% joint venture interest through total expenditure of A$20 million over a two stage earn-in, across a five-year period. Greatland Gold will manage the Juri Joint Venture until the end of calendar year 2021, after which Newcrest has the right to be appointed as Manager.
Initial scout drill testing of the Goliath, Outamind and Los Diablos targets in the Paterson Range East area has been completed. Assay results are pending. Subsequent work programmes for the next period, including drilling, will focus on the Parlay target within the Black Hills Project.

Notes for Editors:
Greatland Gold plc is a London Stock Exchange AIM-listed (AIM:GGP) natural resource exploration and development company with a current focus on precious and base metals.
The Company's flagship asset is the world class Havieron gold-copper project in the Paterson region of Western Australia. This asset is held in joint venture with Newcrest Mining Ltd. Havieron is located approximately 45km east of Newcrest's Telfer gold mine, processing plant and existing infrastructure.
The box cut for the decline to develop the Havieron ore body was commenced in February 2021. The portal was complete in April 2021 and the decline commenced later that month. In addition, a substantial ongoing growth drilling programme is presently underway at Havieron which is being undertaken in conjunction with preparation of a Pre-Feasibility Study ("PFS"). Newcrest is managing the preparation of the PFS which is expected to be released in H2 2021.
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.
Greatland is seeking to identify large mineral deposits in areas that have not been subject to extensive exploration previously. It is widely recognised that the next generation of large deposits will come from such under-explored areas and Greatland is applying advanced exploration techniques to investigate a number of carefully selected targets within its focused licence portfolio.
The Company is actively investigating a range of new opportunities in Australia for precious and strategic metals and will update the market on new opportunities as and when appropriate.

Section 1 Sampling Techniques and Data
| Criteria |
Commentary |
| 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 25418m from 29 drillholes, 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 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 4kg. 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, the sample and 10 samples either side are re-ground or re-screened. There are very few instances of <95% passing the second grind. An assessment of the grind size verses Au grade has shown that rare mineralised assays are affected by grinding issues. 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 700m 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. |
Section 2 Reporting of Exploration Results
| 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. Newcrest has now met the Stage 3 expenditure requirement (US$45 million) and is entitled to earn an additional 20% joint venture interest, resulting in an overall joint venture interest of 60%. Newcrest has the right to earn up to a 70% interest and acquire a further 5% 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. The mining tenement M45/1287 wholly replaces the 12 sub-blocks of exploration tenement E45/4701 (former exploration tenement on which the Havieron Project is based) and was granted on 10 September 2020. All obligations with respect to legislative requirements including minimum expenditure are maintained in good standing for prior exploration tenement E45/4701. |
| 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. |

APPENDIX II
Drillhole Data
Havieron Project, Paterson, Western Australia
Reporting Criteria: Intercepts reported are downhole drill width (not true width) Au >0.20ppm (0.2g/t Au) and minimum 20m downhole width with maximum consecutive internal dilution of 10m. Average grades are based on length-weighting of uncut sample grades. Also highlighted are high grade intervals of Au >1.0ppm (1g/t Au) and minimum 10m downhole width with maximum consecutive internal dilution of 5m, and intervals of >30g/t with no internal dilution which are greater or equal to 30 gram metres (Au_ppm x length) are tabled. Gold grades are reported to two significant figures, the downhole lengths are rounded to 0.1m which may cause some apparent discrepancies in interval widths. Samples are from core drilling which is PQ, HQ or NQ in diameter. Core is photographed and logged by the geology team before being cut. Half core PQ, HQ and NQ samples are prepared for assay and the remaining material is retained in the core farm for future reference. Each assay batch is submitted with duplicates and standards to monitor laboratory quality. Total depth (end of hole) is rounded to one decimal place for reporting purposes. Collars denoted "^^" have been reported previously.
