Quarterly Exploration Report For the three months ended 31 December 2021
Red Chris and Havieron drilling continues to expand mineralisation
At Red Chris, drilling continues to expand the footprint and continuity of the higher grade mineralisation at East Ridge.
Drilling has expanded mineralisation to the east, hole RC740 returned 156m @ 0.73g/t Au & 0.71% Cu from 1,452m, including 86m @ 1.2g/t Au & 0.97% Cu from 1,522m and hole RC745^^ returned 366m @ 0.45g/t Au & 0.57% Cu from 728m, including 36m @ 1.4g/t Au & 1.2% Cu from 960m. RC740, located 100m east of RC745 is one of the most eastern holes drilled to date. Mineralisation remains open to the east.
Holes RC739 and RC748 demonstrated continuity of higher grade. RC739^^ returned 390m @ 0.63g/t Au & 0.48% Cu from 1,088m, including 44m @ 2.0g/t Au & 1.3% Cu from 1,402m. This hole is located 100m east of RC727 (previously reported, returned 346m @ 1.1g/t Au & 0.79% Cu from 1,046m, including 56m @ 3.5g/t Au & 1.8% Cu from 1,336m) and extended the higher grade a further 100m to the east. RC748 returned 452m @ 0.60g/t Au & 0.54% Cu from 1,192m including 106m @ 1.2g/t Au & 1.0% Cu from 1,384m. The hole is located 100m below RC727 (previously reported) and extended the higher grade mineralisation a further 100m down dip.
Drilling to define the extent of the East Ridge mineralised corridor is ongoing.
At Havieron, growth drilling continues to identify high grade extensions to the South East Crescent Zone at depth as well as high grade crescent style mineralisation within extensions of the Eastern Breccia. Highlights include:
South East Crescent extensions more than 250m below the current Mineral Resource estimate continued to return high grade results including HAD086W3^^ 44.7m @ 7.1g/t Au & 0.17% Cu from 1,412m including 20.2m @ 15g/t Au & 0.29% Cu from 1,421m.
High grade extensions to the Eastern Breccia 200m to the SW of previous drilling include HAD104: 62.5m @ 5.9g/t Au & 0.30% Cu from 1,546.5m including 49.4m @ 7.1g/t Au & 0.38% Cu from 1,554.6m. This result is the most significant seen outside of the South East Crescent Zone to date, and confirms the potential for this separate NW trending Eastern Breccia corridor to host Crescent style high grade mineralisation. Drilling is now focussed on defining the extents of this higher-grade mineralisation which remains open in all directions.
At the South East Crescent Zone the infill drilling completed validates both geological and grade continuity.
Drill testing of new geophysical targets 2km outside of the Havieron system has commenced.
Melbourne, Australia--(Newsfile Corp. - January 27, 2022) - Newcrest Mining Limited (ASX: NCM) (TSX: NCM) (PNGX: NCM) Newcrest Managing Director and Chief Executive Officer, Sandeep Biswas, said, "Our drilling results across the quarter continue to demonstrate the quality of our Red Chris and Havieron assets. At Red Chris, results at East Ridge have expanded the footprint of the mineralised corridor, with the latest drilling intersecting higher grade mineralisation within the eastern extents of the prospect. The high grade mineralisation remains open to the east and at depth which provides exciting potential for the resource base at Red Chris to grow over time."
"At Havieron, our exploration continues to demonstrate growth upside, with HAD104 in the Eastern Breccia intersecting the highest grade mineralisation observed to date outside the South East Crescent Zone. This Eastern Breccia corridor sits outside of the Inferred Mineral Resource estimate and confirms the prospectivity of the Havieron region to host additional high grade zones and the significant potential for further resource growth," said Mr Biswas.

Red Chris, British Columbia, Canada(2)
Red Chris is a joint venture between Newcrest (70%) and Imperial Metals Corporation (30%) which is operated by Newcrest.
The Brownfields Exploration program is focused on the discovery of additional zones of higher grade mineralisation within the Red Chris porphyry corridor, including targets outside of Newcrest's initial Mineral Resource estimate. During the period, there were up to eight diamond drill rigs in operation. A further 21,275m of drilling has been completed from 27 drill holes, with all drill holes intersecting mineralisation (except 15 drill holes which were dedicated geotechnical holes). This contributed to a total of 217,349m of drilling from 199 drill holes since Newcrest acquired its interest in the joint venture in August 2019.
At East Ridge, located adjacent to the East Zone, drilling is ongoing with 18 holes completed and 4 in progress. The follow up drilling is being completed on a nominal 100m x 100m grid to determine the footprint of the mineralisation and demonstrate the continuity of the higher grade mineralisation. Drilling to date has tested a corridor 800m long and to a vertical extent of 1,000m.
Results for the reporting period include:
Drilling continues to expand the footprint and continuity of the higher grade. Holes RC740, RC745 and RC735 have extended the corridor to the east, with hole RC740 being the deepest hole drilled to date. Mineralisation remains open to the east and at depth. Holes RC739 and RC748 have demonstrated continuity of the higher grade, by extending higher grade mineralisation 100m to the east and 100m below RC727 (previously reported, returned 346m @ 1.1g/t Au & 0.79% Cu from 1,046m, including 56m @ 3.5g/t Au & 1.8% Cu from 1,336m).
The East Ridge mineralised corridor (>0.4g/t Au and >0.4% Cu) now extends over 800m long, up to 1,000m high and 125m wide, with higher grade (>0.8g/t Au and >0.8% Cu) in several smaller pods over an area 500m high, 400m long and 100m wide.
East Ridge is located east of East Zone and is outside of Newcrest's initial Mineral Resource estimate, supporting the potential for resource growth over time. Follow-up drilling is in progress to further define the extent and continuity of this high grade mineralisation.
Approximately 50,000m of growth-related drilling is planned for calendar year 2022 from eight drill rigs.
Refer to Appendix 1 for additional information, and the Drillhole data table for all results reported during the period.

Havieron Project, Western Australia, Australia(3)
The Havieron Project is operated by Newcrest under a Joint Venture Agreement (JVA) with Greatland Gold. Following the delivery of the Pre-Feasibility Study on 12 October 2021, Newcrest is now entitled to an additional 10% interest in the Havieron Project, which would bring Newcrest's cumulative interest to 70%. Newcrest has an option to acquire an additional 5% Joint Venture interest for fair market value, exercisable during the 12 months from 12 December 2021. In December 2021, Newcrest provided notice to Greatland Gold to begin the process under the JVA to seek to agree the option price for the additional 5% Havieron Joint Venture interest. The JVA includes tolling principles reflecting the intention of the parties that, subject to a successful exploration program, Feasibility Study and a positive decision to mine, the resulting joint venture mineralised material will be processed at Telfer.
The Havieron Project is centred on a deep magnetic anomaly located 45km east of Telfer in the Paterson Province. The deposit is overlain by more than 420m of post mineral Permian cover. A total of 14,481m of new drilling has been completed from 18 drill holes during the period. This report is covering results from 33 holes (including 5 holes completed this period, and 28 holes from the September quarter). Of the reported holes, 22 holes returned significant assay intercepts in excess of 50 gram metres Au (Au ppm x length m). A total of 226,492m of drilling from 272 drill holes has been completed since Newcrest commenced exploration activity (excluding holes in progress, abandoned holes, or drill holes which have not been sampled).
Drilling in the reporting period was focused on potential resource growth at the South East Crescent Zone, 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:
At the South East Crescent Deeps, 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. New results from six drill holes have been received, with results from five drill holes returning greater than 50 gram metre intercepts. Refer to Appendix 2 for all results reported.
Results include:
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 current 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 South East Crescent Zone at depth. Drilling continues to assess the depth extents of the South East Crescent Zone which now has a vertical extent of over 900m.
At the Eastern Breccia, assays for an additional four holes targeting strike extensions from previously reported drill holes HAD083 and HAD084 have been received. Interpretation of the results indicate the potential for a separate north west trending corridor, with an alteration footprint of approximately 600m, with crescent like higher grade zones developed internal to this Eastern Breccia. The most significant intercept to date was returned during the reporting period in HAD104 returning 62.5m @ 5.9g/t Au & 0.30% Cu from 1546.5m, including 49.4m @ 7.1g/t Au & 0.38% Cu from 1,554.6m. The intercept is related to massive sulphide and quartz infill, which is characteristic of the Crescent zone, and is the first intercept on the eastern side of the dolerite. The intercept is ~200m SW of the previously reported initial eastern breccia drillholes HAD083 and HAD084. HAD104 has highlighted the potential for this separate NW trending eastern breccia corridor to host crescent style high grade mineralisation. Drilling is now focussed on defining the extents of this higher grade mineralisation seen in HAD104 which remains open in all directions.
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, is located approximately 1 km to the west of Havieron North and is centred on a prominent gravity high anomaly. The initial Havieron North drillhole did not return any significant results but did intercept alteration consistent with that seen at Havieron. Assay results are awaiting for the two completed Zipa drillholes. Drilling continues to test these and other targets outside of the main Havieron deposit.
South East Crescent Zone Inferred Mineral Resource infill drilling was finalised during the period, with 3 further drill holes completed, and assays reported for all twenty-one drill holes (including 17 drill holes from the prior period). This drilling is designed to infill the South East Crescent Zone Inferred Mineral Resource volume to 50m x 50m spacing to support the potential upgrade of a significant portion of the Inferred Mineral Resource to an Indicated Mineral Resource. Results received from infill drilling support the modelled grade and thickness within the South East Crescent Zone Mineral Resource extents.
Results include:
All drill programs have now returned to growth targets with up to eight drill rigs operational. Growth drilling continues to show potential for resource additions outside of the existing Inferred Mineral Resource limits, including:
Refer to Appendix 2 for additional information and Drillhole data table for all results reported during the period.

Wilki Project, Western Australia, Australia
The Wilki Project is an exploration farm-in and joint venture with Antipa Minerals Limited (Antipa). The project area covers a strategic landholding of ~2,200km2 surrounding the Telfer operation and is adjacent to the Havieron Project. Newcrest entered into this exploration farm-in and joint venture agreement with Antipa on 11 March 2020. Newcrest currently has a 9.9% shareholding in Antipa.
Newcrest has elected to proceed to the next stage (Stage 1) of the farm-in agreement following completion of the initial exploration expenditure commitment (A$6 million). Newcrest has the potential to earn a 51% joint venture interest in the Wilki Project through expenditure of a further A$10 million by March 2025 during Stage 14.
Scout diamond drilling of the Tyama Prospect was completed during the period. Results returned low level Zn anomalism. In addition, ground electromagnetic surveys were completed over priority target areas during the period. Processing and interpretation has commenced.
Juri Joint Venture, Western Australia, Australia
The Juri Joint Venture is a farm-in and joint venture agreement with Greatland Gold with respect to the Black Hills and Paterson Range East projects, located within the Paterson Province approximately 50km from the Telfer operation and in proximity to the Havieron Project. The joint venture covers an area of approximately 248km2.
Newcrest has met the Stage 1 exploration expenditure (A$3 million) and now holds a 51% interest in the Juri Joint Venture. Under the terms of the agreement, Newcrest has the potential to earn an additional 24% joint venture interest (for a cumulative 75% joint venture interest) through expenditure of a further A$17 million over three years during Stage 24.
Follow up ground electromagnetic surveys over additional targets at both Paterson Range East and Black Hills were completed during the period.
Tennant East, Northern Territory, Australia
Work programs focussing on undercover targets at the Tennant East project (located 200km east of Tennant Creek) have been completed over the initial six target areas. Induced polarisation (IP) data processing is currently progressing. Scout drilling is planned to be completed on defined coincident gravity, magnetic and IP targets in calendar year 2022.
Nevada, USA
Drill activities were completed at the Jarbidge project in north-eastern Nevada during the period with testing focused on low sulfidation epithermal vein targets. Assay results are pending, but visually the targets are downgraded. As a result, Newcrest has provided notice of termination with respect to several of the option agreements underlying the Jarbidge project with the decision to retain any remaining option agreements pending the receipt of outstanding assay results and conducting required reclamation activities.
Drilling has commenced at the Fortuity89 project in south-western Nevada.
Central Andes, Northern Chile
Drilling was conducted across Newcrest's Chilean exploration project portfolio with 2,654m drilled during the quarter at Atlas and El Dorado (Gorbea Option and Farm-in Agreement with Mirasol Resources Ltd.), Mioceno (Option and Farm-in Agreement with Cornerstone Capital Resources Inc.) and Esparta (Option Agreement with private individuals). Interpretation of the data is ongoing, with assay results pending.
Northern Andes, Ecuador
Scout drilling commenced in November at the Gamora Project, located within southeast Ecuador. This work is being conducted by Newcrest as the operator under an earn-in agreement with Lundin Gold. pursuant to which Newcrest can earn up to a 50% interest in eight exploration concessions. The concession area covers strategic landholdings to the north and south of Lundin Gold's Fruta del Norte mining operation.
The program at Gamora is focused on testing priority copper-gold porphyry targets with two core holes completed with assays pending. Drilling is ongoing.
Appendix 1
Red Chris (70% Newcrest): JORC Table 1Section 1: Sampling Techniques and Data
| Criteria | Commentary |
| Sampling techniques | Core samples are obtained from core drilling. HQ and NQ diameter diamond core was drilled on a 3, 4.5m or 6m run. Core was cut using an automatic core-cutter and half core sampled at 2m intervals. Cover sequences were not sampled. |
| Drilling techniques | Core drilling was advanced with HQ3, HQ, NQ3 and NQ diameter coring configuration. Core from inclined drill holes are oriented on 3, 4.5m or 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. |
| Logging | Geological logging recorded qualitative descriptions of lithology, alteration, mineralisation, veining, and structure (for all core drilled - 21,275m in 27 holes - all holes intersected mineralisation except for 15 dedicated geotechnical holes, 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.All geological and geotechnical logging was conducted at the Red Chris Mine. Digital data logging was captured, validated and stored in an acQuire database. All drill cores were photographed, prior to cutting and/or sampling the core. |
| 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 Red Chris Mine core processing facility. Half core samples were collected in plastic bags together with pre-numbered sample tags and grouped in wood crates for dispatch to the laboratory. Sample weights typically varied from 5 to 10kg. Sample sizes are considered appropriate for the style of mineralisation. Drill core samples were freighted by road to the laboratory.Sample preparation was conducted at the independent ISO 9001 certified and ISO 17025 accredited Bureau Veritas Commodities Canada Ltd Laboratory, Vancouver (Bureau Veritas). Samples were dried at 650C, and crushed to 95% passing 4.75 mm, and the split to obtain up to 1kg sub-sample, which was pulverised (using LM2) to produce a pulped product with the minimum standard of 95% passing 106μm.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 Bureau Veritas. All samples were assayed for 59 elements using a 4-acid digestion followed by ICP-AES/ICP-MS determination (method MA250). Gold analyses were determined by 50g fire assay with ICP-ES finish (method FA350). Carbon and Sulphur were determined by Leco (method TC000) and mercury using aqua regia digestion followed by ICP-ES/MS determination (method AQ200). 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 the 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.Due to the limited extent of the drilling program to date, extended quality control programs are yet to be undertaken, whereby pulped samples will be submitted to an umpire laboratory and combined with more extensive re-submission programs. 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 sample tags 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 drill core intervals and assessment of high resolution core photography. The verification of significant intersections has been completed by company personnel and the Competent Person/Qualified Person.No adjustments are made to assay data, and no twinned holes have been completed. Drilling intersects mineralisation at various angles. 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 RTK GPS with GNSS with a stated accuracy of +/- 0.025m.Drill rig alignment was attained using an electronic azimuth aligner (Reflex TN14 GYROCOMPASS). Downhole survey was collected at 9 to 30m intervals of the drill hole using single shot survey (Reflex EZ-SHOT). At the end of hole, all holes have been surveyed using a continuous gyro survey to surface (Reflex EZ-GYRO). Topographic control is established from PhotoSat topographic data and derived digital elevation model. The topography is generally low relief to flat, with an average elevation of 1500 m, with several deep creek gullies.All collar coordinates are provided in the North American Datum (NAD83 Zone 9). |
| Data spacing and distribution | The drill hole spacing ranges from 100 - 200m in lateral extent within an area of 1.5km2 at the East Ridge, 1.5km2 at the East Zone, 1.5km2 at the Main Zone and 1.5km2 at the Gully Zone. No sample compositing is applied to samples. |
| Orientation of data in relation to geological structure | Drilling of reported drill holes RC735, R739, RC740, RC745, RC746, RC747, RC748, RC752 and RC754 are oriented perpendicular to the intrusive complex. The intrusive complex has an east-northeast orientation, with drilling established on a north-northwest orientation. Drill holes exploring the extents of the East Ridge, East Zone, Main Zone and Gully Zone mineral system intersected moderately dipping volcanic and sedimentary units cut by sub-vertical intrusive lithologies. Steeply dipping mineralised zones with an east-northeast orientation have been interpreted from historic and Newcrest drill holes. |
| 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 Red Chris Mine core yard every shift. Geological and geotechnical logging, high resolution core photography and cutting of drill core was undertaken at the Red Chris core processing facility. Samples were freighted in sealed bags with security tags by road to the laboratory, and in the custody of Newcrest representatives. Sample numbers are generated from pre-labelled sample tags. All samples are collected in pre-numbered plastic bags. Sample tags are inserted into prenumbered plastic bags together with the sample.Verification of sample numbers and identification is conducted by the laboratory on receipt of samples, and sample receipt advice 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 the laboratory analytical services. Any discrepancies logged at the receipt of samples into the laboratory analytical services are validated. |
| Audits or reviews | Due to the limited duration of the program, no external audits or reviews have been undertaken. Internal verification and audit of Newcrest exploration procedures and databases are periodically undertaken. |

Appendix 2Havieron Project (Greatland Gold Plc - Joint Venture Agreement): JORC Table 1Section 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 is 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 - 13,183 m for 21 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 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 programs including pulp samples submitted to an umpire laboratory and combined with more extensive re-submission programs 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 company personnel and the Competent Person/Qualified Person.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 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 1000m 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 extended to 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 Havieron facility. High resolution core photography and cutting of drill core was undertaken at the Havieron 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. Following the delivery of the PFS on 12 October 2021, Newcrest is entitled to earn an additional 10% joint venture interest, resulting in an overall joint venture interest of 70% (Greatland Gold 30%). Newcrest also has an option to acquire a further 5% at fair market value and in December 2021, Newcrest provided notice to Greatland Gold to start the process under the joint venture process to seek to agree the option exercise price for the 5% interest. Newcrest and WDLAC are parties to an 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 programs 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. |
| 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 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. |

Drillhole data(1)
Havieron Project, Paterson Province, 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 samples 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 which are greater or equal to 30 gram metres (Au_ppm x length) are tabled. Gold and copper 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 with a * show partial results, with further significant assays to be reported in subsequent exploration updates.

There may be other factors that could cause actual results or events not to be as anticipated, and many events are beyond the reasonable control of Newcrest.

Forward looking statements in this document speak only at the date of issue. Except as required by applicable laws or regulations, Newcrest does not undertake any obligation to publicly update or revise any of the forward looking statements or to advise of any change in assumptions on which any such statement is based.
