Newcrest Mining Limited (ASX: NCM) (TSX: NCM) Newcrest Managing Director and Chief Executive Officer, Sandeep Biswas, said, “Our extensive growth drilling program has delivered several new exciting high grade intercepts at Havieron, including 85m @ 11gt Au and 0.29% Cu. These results highlight the potential for significant high grade depth extension of the South East Crescent zone. We are also excited by our continued exploration success at Red Chris, with drill results from East Ridge and Main Zone expanding the footprint of the higher grade mineralisation. East Ridge is our new discovery that is located outside of our initial Red Chris Mineral Resource estimate with drill results to date supporting the potential for resource growth at Red Chris over time. Drill results in the Main Zone have confirmed the potential for higher grade mineralisation which could support additional mining fronts beneath and to the south west of the open pit.”

Red Chris, British Columbia, Canada(2)

Red Chris is a joint venture between Newcrest (70%) and Imperial Metals Corporation (30%). Newcrest acquired its interest in, and operatorship of, Red Chris on 15 August 2019.

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 Mineral Resource estimate. During the period, there were up to eight diamond drill rigs in operation. A further 15,342m of drilling has been completed from 11 drill holes, with all drill holes intersecting mineralisation (except two which were dedicated geotechnical holes). This contributed to a total of 136,631m of drilling from 111 drill holes since Newcrest acquired its interest in the joint venture.

At East Ridge, located adjacent to the East Zone, Newcrest has discovered a new zone of higher grade mineralisation, with previously reported hole RC678^^ returning 198m @ 0.89g/t Au & 0.83% Cu from 800m, including 76m @ 1.8g/t Au and 1.5% Cu from 908m. The style of mineralisation and grade tenor is similar to that seen in the high grade pods from the East Zone.

Final results from follow-up drill hole RC684 drilled 100m down dip of RC678 returned 252m^ @ 0.46g/t Au & 0.53% Cu from 814m, including 98m^ @ 0.85g/t Au & 0.86% Cu from 962m. This hole demonstrates the continuity of the East Ridge zone over 100m vertically.

Results from follow-up drill hole RC688 drilled 100m east of RC678 returned 344m @ 0.70g/t Au & 0.75% Cu from 776m including 170m @ 1.1g/t Au & 1.1% Cu from 892m. This hole demonstrates the continuity of the East Ridge zone over 100m horizontally.

East Ridge is located 300m east of East Zone and outside of Newcrest’s Red Chris Mineral Resource estimate, and it supports the potential for resource growth over time. Mineralisation is open and extends the eastern side of the porphyry corridor as shown in Figures 1 and 2. Follow-up drilling to further define the extent and continuity of this high grade mineralisation continues.

In the Main Zone, drilling has confirmed the potential for further higher grade mineralisation which could support additional mining fronts, beneath and to the south west of the open pit. Results from RC679^^ (previously reported), which followed up historic results south west of the Main Zone pit, returned 456m^^ @ 0.37g/t Au & 0.42% Cu from 418m, including 98m^^ @ 0.71g/t Au & 1.0% Cu from 440m. Results from follow-up drill hole RC683 drilled 100m east of RC679 returned 300m @ 0.41g/t Au & 0.51% Cu from 260m, including 114m @ 0.67g/t Au & 0.85% Cu from 390m. This hole demonstrates the continuity of the higher grade mineralisation over 100m horizontally. The mineralisation is located within Newcrest’s Mineral Resource estimate. Drilling to define the extent and continuity of this high grade mineralisation is planned.

Approximately 50,000m of growth-related drilling is planned this calendar year with the increase to eight drill rigs in April 2021. Further drilling of the East Ridge is underway to define the extent of the mineralisation. Further targets along the porphyry corridor and neighbouring GJ property have been identified with the potential to conduct drilling to test these targets in the future.

Refer to Appendix 1 for additional information, and Drillhole data table for all results reported during the period.

Havieron Project, Western Australia3

The Havieron Project is operated by Newcrest under a Joint Venture Agreement with Greatland Gold. 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 Gold 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 (including the delivery of a Pre-Feasibility Study) in a four-stage farm-in over a six year period that commenced in May 2019. Newcrest may acquire an additional 5% interest at the end of the farm-in period at fair market value. The Joint Venture Agreement 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. Newcrest commenced drilling in May 2019. Drilling activities from seven drill holes resulted in 5,757m of drilling completed since 31 March 2021, with all drill holes intersecting mineralisation. A total of 164,420m of drilling from 190 drill holes has been completed since Newcrest commenced exploration activity.

At the South East Crescent, growth drilling to expand the resource has commenced with two drill holes HAD086W1 and HAD133 extending the high grade mineralisation ~80m below the base of the Inferred Mineral Resource. 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) and highlights significant high grade depth extension of the South East Crescent zone. Drilling continues to define the extent of the high grade South East Crescent zone.

Results from HAD086W1 and HAD133 include:

  • HAD086W1
    • 99.7m @ 2.5g/t Au & 0.85% Cu from 1,308m
    • including 50.4m @ 4.3g/t Au & 1.6% Cu from 1,313.6m
  • HAD133
    • 85m @ 11g/t Au & 0.29% Cu from 1,345m
    • including 13m @ 32g/t Au & 0.46% Cu from 1,363m
    • including 14.5m @ 32g/t Au & 0.33% Cu from 1,396.5m

HAD097W3 and HAD136 returned Crescent intercepts within the current Inferred Mineral Resource footprint. These holes were designed to target depth extensions in the breccia mineralisation. They also show good alignment with modelled grade and thickness within the South East Crescent zone which further supports the continuity of high grade.

Results include:

  • HAD097W3
    • 47.8m @ 2.3g/t Au & 0.28% Cu from 620.2m
    • including 28.3m @ 3.8g/t Au & 0.45% Cu from 639.7m
  • HAD136
    • 55.2m @ 2.5g/t Au & 0.65% Cu from 501m
    • including 24.5m @ 5.4g/t Au & 0.95% Cu from 506.8m

At the Northern Breccia results from an additional three growth holes identified mineralisation outside of the Inferred Mineral Resource footprint. These results support extensions to breccia mineralisation in the north west of the system and further highlights the potential for resource extensions outside of the South East Crescent zone.

Results include:

  • HAD089W1
    • 81.3m @ 1.2g/t Au & 0.04% Cu from 1,009.7m.

Currently, all drill rigs are operational on the growth drilling program with a focus on the South East Crescent depth extensions below 4,200mRL, the north west extensions of the Northern Breccia Zone and higher grade crescent-like mineralised zones. The intent of this drilling is to support 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 joint venture area with Greatland Gold, have been identified with the potential to conduct drilling to test these targets in the future.

Refer to Appendix 2 for additional information, and Drillhole data table for all results reported during the period.

Wilki Project, Western Australia

The Wilki Project covers a strategic landholding of ~2,200km2 surrounding the Telfer operation and is also in close proximity to the Havieron Project. Newcrest entered into this exploration farm-in and joint venture agreement with Antipa Minerals Limited on 11 March 2020.

During the period, Newcrest participated in Antipa’s share placements to maintain its 9.9% shareholding.

Exploration activity during the period included the re-interpretation and validation of anomalies generated from the previously reported Airborne Electromagnetic Survey (AEM) completed in CY20. Prioritisation of targets for the CY21 drill program has been completed utilising the AEM anomalies and other datasets including magnetics and geochemistry.

It is anticipated that the field program for the CY21 field season including drill testing will commence in June 2021.

Juri Joint Venture, Western Australia

On 30 November 2020, Newcrest announced its entry into the Juri Joint Venture which 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.

Exploration activities have commenced with an initial program designed to drill test the Goliath, Outamind and Los Diablos targets in the Paterson Range East area. An initial scout drill program has been completed at the Goliath target with assay results pending. Subsequent work programs, including drilling, will also focus on the Parlay target within the Black Hills Project.

Tennant East, Northern Territory

Newcrest is the holder of six granted titles as well as seven application areas in the recently recognised Tennant East domain. Drill testing on the initial two target areas of Lantern and Sabretooth commenced in late April 2021.

Nevada, USA

Newcrest recently entered into an option and earn-in agreement with Discovery Harbour Resources Corp. on their Fortuity 89 property located in the Great Basin, Nevada. Fortuity 89 is characterised by limited outcrop in a large gravel covered plain. The limited outcrop is strongly altered, and other indications are consistent with the area having potential for epithermal gold mineralisation. On ground exploration work has commenced with target generation activities including mapping, sampling and geophysical surveys underway.

GJ Project, British Columbia, Canada

At the GJ Project, which is part of the Red Chris joint venture between Newcrest (70%) and Imperial Metals Corporation (30%), Newcrest is using its strong exploration expertise, to test the depth potential of the Donnelly Zone, part of a 10km porphyry corridor (Groat Stock). An initial program of two holes for 2,500m is planned to commence in the December 2021 half.

Section 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 -15,342m in 11 holes- all holes intersected mineralisation except for 2 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 plastic bags 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 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 RC676, RC683, RC684, RC686, RC687 and RC688 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 2

Havieron Project (Greatland Gold Plc – Joint Venture Agreement): JORC Table 1
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 – 4,798 m for 7 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 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. 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 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 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. 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 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.
Diagrams As provided.

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 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.

  • Lihir Phase 14A PFS indicates potential for growth and large scale, long life, low cost production
  • Confirms Lihir’s pathway to become a 1Moz+ gold producer for at least 10 years from FY241
  • $179m investment projected to deliver outstanding return metrics of 37% IRR & 2.6 year payback2,3,4
  • Increases Lihir’s Ore Reserves by 1 million ounces5
  • Project implementation to enhance operational flexibility and risk management
  • Potential to deploy Phase 14A mining techniques in other parts of the mine to unlock more value
  • Feasibility Study expected to be completed in the second half of FY226

Newcrest Mining Limited (ASX: NCM) (TSX: NCM) (PNGX: NCM) is pleased to announce that the Newcrest Board has approved the Lihir Phase 14A Pre-Feasibility Study (the Phase 14A Study), enabling the commencement of the Feasibility Study and Early Works Program.

The Study focuses on extending the Phase 14 cutback and safely steepening the walls of the pit utilising civil engineering techniques to access existing Indicated Mineral Resources that would have otherwise been inaccessible through standard mining techniques. The Study integrates Phase 14A’s future mine design and sequence into Lihir’s mine plan and establishes the expected costs, schedule and sustainable production rate.

Newcrest Managing Director and Chief Executive Officer, Sandeep Biswas, said “The findings of our Lihir Phase 14A Pre-Feasibility Study accelerate the realisation of our aspiration for Lihir to be a 1 million ounce plus per annum producer from FY24, which will benefit landowners, all Lihirians and PNG. Phase 14A increases Lihir’s Ore Reserves, brings forward gold production and improves operational flexibility by establishing an additional independent ore source. The Study also highlights the opportunity for Phase14A techniques to be applied to future cutbacks at Lihir, potentially unlocking more value. We have also confirmed the deferral of the need for the Seepage Barrier to Q2 FY26, with the potential to further defer the timing of the barrier.”

Summary of Phase 14A Study Findings2,3,7

The Phase 14A Study has identified the following:

  • Estimated project capital expenditure of $179 million
  • Internal Rate of Return (IRR) of 37% (real, after tax)
  • Payback of 2.6 years4
  • Net Present Value (NPV) of $284 million[8]
  • Mill feed increase of 483koz contained gold, with ~400koz of additional gold produced from FY23 to FY26
  • Additional Life of Mine (LOM) gold production of 965koz

The Feasibility Study is expected to be completed in the fourth quarter of FY226, with the expenditures and study scope expected to include:

  • Early Works expenditure of $47 million for fleet procurement and initial bench establishment
  • Trial works for ground support anchors to validate design, costs and schedule
  • Additional drilling and test work to validate ore deposit knowledge

The Lihir Ore Reserves estimate has been updated to include the conversion of the Phase 14A Indicated Mineral Resource to Probable Ore Reserves, increasing Lihir’s Total Ore Reserves by 1Moz to 23Moz as at 30 June 20215.

Mining of Phase 14A is expected to take place between FY22 and FY26. Ore mined from this Phase will replace lower grade ore feed to the processing plant, with an initial 13Mt of high and medium grade ore from Phase 14A planned to be fed between FY22 and FY26. Lower grade material will be stockpiled and fed progressively over the remaining LOM. This is expected to deliver an additional 965koz of gold production over the LOM.

In addition, Newcrest has completed its Seepage Barrier Feasibility Study, which enables further definition of the expected construction costs and schedule. The findings from the project field trials indicate that the Seepage Barrier can be constructed using hydromill cutters and grouting methods. Approval of the Seepage Barrier Feasibility Study to move to Execution has been deferred until FY23, in line with the findings of the Lihir Mine Optimisation Study (LMOS) which established that the eastern limits of Phases 16 and 17 could be moved further east, deferring the need for the Seepage Barrier by ~18 months to Q2 FY26.

Phase 14A Overview2

In February 2021, Newcrest announced the findings of the LMOS which included the identification of a new, essentially brownfield opportunity called Phase 14A. The Phase 14A Study focused on extending the Phase 14 cutback and safely steepening the walls of the pit by utilising civil engineering techniques to access existing Indicated Mineral Resources which would have otherwise been inaccessible through standard mining techniques. The Phase 14A cutback is expected to provide an additional mining front enabling further flexibility for fresh competent ore feed. The Phase 14A cutback is fully permitted and is within the existing mine lease.

Field trials of the wall support technology are planned for the December 2021 quarter6, with long lead materials to be ordered and the engagement of specialist contractors in progress.

The addition of Phase 14A into the Lihir mine plan accelerates Newcrest’s aspiration for Lihir to be a 1Moz+ per annum producer from FY24.

Mining of Phase 14A is expected to take place from FY22 to FY26 and include:

  • Total ex-pit mining of 34Mt, including 13Mt of high and medium grade ore at an average of 3g/t, which will displace lower grade ore (mostly stockpile) that would otherwise have been processed in the mill
  • An uplift in the total mill feed grade and an additional 483koz of gold in feed and 400koz recovered gold over FY23 – FY263

Backfilling the cutback will occur after the completion of mining and will act as a buttress supporting long-term stability of the highwall.

A program of infill resource definition drilling and trial installations of the ground anchors is underway and will be completed in FY22. This program is expected to improve resource definition, further reducing project risk.

The Phase 14A design utilises civil engineering techniques, in conjunction with existing mining practices, to increase pit wall angles. The upper Argillic horizons without ground support typically have an unsupported slope angle of ~45° which has been increased to ~77° using soil anchors to provide stability. The soil anchors will be installed in the upper benches of the cutback to support the steeper wall angles in these areas. The slope angles of the lower benches will be similar to the existing walls in Phase 14. The increase in pit wall angle enables access to ore within the current permitted pit shell.

To integrate with the civil construction, mining will be conducted by a dedicated mining fleet which will comprise a small excavator and dump trucks mining 3m flitches. The 3m flitches are required to provide a working platform for installation of soil anchors at 3m vertical spacings.

The Lihir base case gold production schedule projects mining rates to increase up to 50Mtpa over the coming years and an average milling rate of 15.5Mtpa9. Ore from Phase 14A is expected to be mined between FY22-26 and will be processed over the LOM.

Base Case Expit Mining to 50Mtpa

Mining rates for Lihir are expected to increase (as identified in the LMOS) over the coming years through a combination of equipment capacity and mining efficiency projects. Additional mining capacity is expected to be delivered through increased truck availability as a result of a program of truck re-builds and the replacement of primary dig units. This program is currently underway and is scheduled to be completed by December 20216.

Mine efficiency improvements identified in the Study include improved fleet utilisation, which is expected to be achieved by increasing operator availability and improving dispatch tactics to reduce equipment delays.

Process Plant Improvements12

Newcrest is currently implementing numerous throughput improvement initiatives which are targeting the achievement of a process plant throughput rate of 15.5Mtpa from FY24. Lihir has previously demonstrated annualised milling performance rates of ~16Mtpa during Q4 FY18 and Q4 FY19.

Recovery Improvements

Recovery improvements are expected to be achieved through a combination of increasing mill feed grades, improved feed blends and recovery improvement projects that are currently in progress. Phase 14A is expected to provide additional fresh ore to the mill, offsetting lower grade and lower performing recovery material types.

The Front End Recovery project is expected to deliver increased recoveries from the beginning of FY23, with further studies assessing recovery improvements underway.

Project Investment

The Phase 14A Project requires a total capital investment of $179 million and comprises:

Activity $m2,7
Study and trial costs 22
Mining and ancillary fleet
(Excluding contractor ground support equipment)
46
Production stripping cost (capitalised) 111
Total 179

Production Stripping

Pre-production stripping of Phase 14A waste material is expected to commence in the second half of FY226. Due to the initial civil works requirements and available bench space, there is expected to be a ramp up of the mining rate to a peak of ~1Mtpa per month through FY23 and FY24.

Phase 14A has a very low strip ratio of 0.66 and as such will start producing HG and MG ore within six months from the commencement of mining. This is expected to provide significant HG mill feed through FY24 and FY25, lifting intended production rates to 1Moz+ per year from FY24, prior to completion of pre-stripping in Phase 179.

Seepage Barrier Feasibility Study Update18

The development of the Kapit orebody requires construction of a seepage barrier to cut off ocean water inflows from Luise Harbour to the open pit as shown in Figures 6 and 7.

The LMOS defined a base case for the Lihir mine plan which found that through further geotechnical analysis, the eastern limits of Phases 16 and 17 could be moved further east, deferring the need for the Seepage Barrier by
18 months to Q2 FY26 to coincide with mining Phase 18.

Additional mining studies are underway to identify further options to delay timing and/or alter the scope for the Seepage Barrier, including:

  • Kapit Pit Slope Optimisation (steepening of pit walls using conventional methods)
  • Installation of a mini seepage barrier to access Phase 18 without the need for the full seepage barrier
  • Combined pit slope steepening with a mini seepage barrier

The Seepage Barrier Feasibility Study has further defined the technical elements, cost and execution of the Seepage Barrier. It has determined:

  • A cut-off wall can be constructed in line with the designed method using standard hydromill cutters and grouting methods with a sea water slurry cooling system and confirmation of the concrete mix
  • An expected capital cost of US$569 million7
  • Construction duration of approximately 72 months

Material Assumptions for Ore Reserves

Lihir is an operating open pit mine on Lihir Island, and the Study incorporates learnings from operational execution to date. Work is progressing on a Feasibility Study for the Phase 14A cutback and any adjustments to the Ore Reserves statement will be made following the completion of the Feasibility Study.

Ore Reserve Classification

All of the in-situ Probable Ore Reserve is based on Indicated Mineral Resources. The Proved Ore Reserve is based on Measured Mineral Resources defined for known and quantified low grade stockpiles. The in-situ resource classification is based on an assessment of geological confidence as a function of geological and mineralisation continuity.

Mining Method

Current mining activity at Lihir is via conventional truck and shovel operation, with offshore barge disposal of waste rock and land based and in-pit stockpiling and reclaim of lower grade ore.

Ore Processing

Ore processing at Lihir involves the main operations of crushing, grinding, flotation, pressure oxidation, leaching and electrowinning to recover gold from relatively high-grade sulphide feed producing gold doré. The Lihir process plant utilises proven technology that is widely used in the gold industry for this style of mineralisation. The ore processing facility has been operating since it was commissioned in 1996 and upgrades took place during 2011 and 2012. Comminution circuit operating optimisations and minor upgrades are planned to achieve a 15.5Mtpa plant capacity12.

The metallurgical recovery assumption for ore feed to the autoclave is dependent on the gold and sulphide sulphur grades, and dependent on sulphur to calcium ratio and proportion of aged stockpile feed for flotation material. Overall metallurgical recovery is reconciled with historic production data, laboratory test samples for stockpiled ore and reflects a partial oxidation metallurgical operating strategy. Average life of mine gold recovery is modelled to be 81-82%.

Cut-Off Grade

Lihir open pit employs a grade based cut-off, taking into account gold price, metallurgical recovery assumptions and site operating costs. The site operating costs include transport and refining costs, royalty charges, mining and processing costs, relevant site general and administration costs and relevant sustaining capital costs. These costs equate to a break even cut off value of US$38/t milled used to define the ultimate pit shell and a marginal cut off value of US$33/t milled or 1.0 g/t gold used to define ore and waste material within the ultimate pit shell.

The marginal site cost is based on an end of mine life low grade stockpile reclaim strategy, reducing the site activity and long term cost base. The mining cost in the marginal site cost represents the stockpile reclaim cost.

Estimation Methodology

Estimation of the Lihir Ore Reserve involved standard steps of mine optimisation, mine design, production scheduling and financial modelling. Factors and assumptions have been based on operating experience and performance at the Lihir operations. The Ore Reserve has been evaluated through a financial model. All operating and capital costs as well as Ore Reserve revenue factors stated in this document were included in the financial model. A discount factor of 4.5% real was applied. This process demonstrated that the Lihir Ore Reserve has a positive NPV. Sensitivities were conducted on the key input parameters including commodity prices, capital and operating costs, ore grade, discount rate, exchange rate and recovery which confirmed the estimate to be robust.

Material Modifying Factors

The resource estimation process allows for ore dilution and recovery to be built into the resource model based on the assumption of the selective mining unit (SMU) as the block size. The SMU assumption is based on the mining fleet size and is consistent with a high mill throughput/bulk mining strategy. Due to the Localised Uniform Conditioning (LUC) approach adopted in the resource model no additional mining dilution or recovery factors have been applied to the Ore Reserve estimate.

This assumption is supported by the actual reconciliation between resource model and mill performance at Lihir to date being within an acceptable uncertainty range for the style of mineralisation under consideration.

The pit optimisation takes into account Inferred Mineral Resources, however only Measured and Indicated Mineral Resources are reported in the Ore Reserve estimate. The Inferred Mineral Resource represents a small portion of material within the ultimate pit design and both the design and financial model are insensitive to the exclusion of this material.

Civil engineered wall support is required for the Phase 14A cutback to allow access to the orebody. The cutback design also requires mining by a fleet of small equipment owing to the narrow ramp configuration required. Allowances for these activities are included in the preparation of the Ore Reserve estimate.

Other Modifying Factors

Lihir Gold Limited and the Lihir Open Pit are in material compliance with all legal and regulatory requirements. Naturally occurring risks that might have a material impact upon the Lihir ore reserve are discussed in the risks section of Newcrest’s Operating and Financial Review (in the Appendix 4E and Financial Report for the year ended 30 June 2021 which is available to view at www.asx.com.au under the code “NCM” and on Newcrest’s SEDAR profile) and include the potential impacts of seismic activity.

Environmental permitting for the Phase 14A Project has been assessed and approved by the Conservation and Environment Protection Authority (CEPA).

The known legal, political, environmental or other risks that could materially affect the potential development of the mineral resources or ore reserves are identified in Sections 3 and 4 of Appendix 1.

Section 1: Sampling Techniques and Data

Criteria Commentary
Sampling techniques Lihir is located in an active geothermal area and procedures have been developed to ensure that all drilling activities are conducted in a safe manner which is appropriate for when zones of high pressure steam are intersected. Data used for the resource estimation is obtained by two main drilling methods – diamond coring and reverse circulation (RC) drilling. All available diamond drill holes are sampled by cutting the core in half with a diamond saw with sample intervals being either 1m or 2m in length. Half the cut core is placed in a calico bag with a sample number and sent to the laboratory for assaying. All RC drilling was sampled at 1m intervals collected via a cyclone and split with a riffle splitter. The riffle split sample size of 4-5kg is placed in a calico bag with a sample number and sent to the laboratory for assaying.
Drilling techniques Drilling is the primary source of data for Mineral Resource estimation at Lihir. Data is obtained from two main drilling methods-diamond coring and RC drilling. The majority of drilling for the resource estimation is diamond drill core (93%), comprising PQ (84.8 mm core diameter), HQ (63.5 mm core diameter) and NQ (47.6 mm core diameter). Very little core orientation is performed on site as the structurally complex and geothermal conditions make it very difficult to obtain accurate orientations. Minor (~7%) of resource drilling is RC (5 1/4′” diameter) completed prior to 2002 used both vertical and angled holes. Since 2002 all resource drilling has been comprised of diamond core. Stockpile drilling is campaigned using an RC rig with a 4″ bit. Hole lengths are routinely 36m.
Drill sample recovery Core recovery is recorded and stored in an acQuire software database. There are only minor zones of core loss or poor core recovery. Core recovery is generally excellent with average core recoveries around 99%. There is no identified relationship between core loss and grade and the style of mineralisation suggests this is unlikely. There are no records of RC sample recovery.
Logging All diamond drill holes are geologically logged. Due to the nature of the intense alteration core is qualitatively logged for lithology and alteration and quantitatively logged for structure and geotechnical parameters. All core is logged and photographed after marking up metre intervals and prior to cutting and sampling. Logging data are entered into the acQuire database via a laptop computer or historically via manual data entry.
Sub-sampling techniques and sample preparation The sampling technique used is considered appropriate for the assessment of Lihir mineralisation. At the completion of drill core logging, the geologist defines which intervals of a drill hole are to be cut for analysis. All recent drilling is analysed on 2m intervals on the metre mark. PQ and HQ sized drill core is sampled by cutting the core in half with a diamond blade saw when intact and competent. The left hand half is placed in a calico bag marked with the appropriate sample number and sent to the assay laboratory for analysis. Where the core is too soft to be cut with a diamond saw, a knife is used to cut the core in the core tray. Where the core is too broken or brittle to be cut by the saw, the fragments are manually sampled. NQ sized core is not cut in half as the entire section is sampled so that sample support is maintained. The standard sampling interval is 2m but has varied over time from 1m to 2m. The remaining half core is stored in the original trays on pallets at the core processing facility.

Lihir has a sample preparation facility at the mine and up to January 2015 there are records for crusher duplicates. Drill core was crushed and RC and blast hole samples were dried and loaded into the pulverisers without laboratory splitting. After 2015 there was a reduction in core sampling and all samples were transferred directly to a bank of 6 * LM5 pulverisers without crushing or splitting. There are two standby jaw crushers with a small single deck riffle splitter which are rarely used.

Sample preparation for analysis is as follows: Samples are crushed if required to 10mm maximum diameter and split to a nominal weight of 2.5 – 3kg using a riffle splitter. Split samples are dried in an oven at 105°C until dry. Each sample is pulverised using a Labtechnics LM5 pulverizing mill to specified grind parameters of 95% passing 106µm. A 200g sub-sample is collected for analysis and submitted to the assay laboratory. Pulp replicates (not duplicates) are routinely undertaken. Crushed and pulp duplicates are collected at the Orange laboratory.

The sample preparation and size is considered appropriate for assessment of bulk tonnage mineral deposits of this type.

Quality of assay data and laboratory tests The Lihir onsite laboratory has been the primary laboratory used for assaying, with some more recent assaying completed at the Newcrest Services laboratory (Orange, NSW).

Samples are routinely assayed for gold and sulphur. Gold analysis is by fire assay with 25g charge and Atomic Absorption Spectroscopy (AAS) finish and detection limit of 0.01ppm (g/t), which is considered complete. Sulphide sulphur is by Labfit method where the sample is ignited at high temperature in a stream of oxygen. The resulting sulphur dioxide is measured by an infra-red detector using a Carbon/Sulphur analyser.

A detailed Quality Assurance/Quality Control (QAQC) program is in place for on-going assessment of sampling and analytical procedures. The process currently involves analysis of blind submissions of certified reference material (standards) to Lihir laboratory, duplicates from the LM5 pulveriser pulp, assayed during the same batch, blind resubmission of pulps to Lihir laboratory, replicate submissions of pulps to an alternative laboratory for analysis, submission of coarse blank samples (non-Lihir Island barren rock samples), checks on grind and crush size from the sample preparation steps and laboratory inspections and monthly QA/QC meetings. A monthly report is prepared detailing QA/QC performance to support the Mineral Resource estimate. There have been 30 standards used, not all of which were certified for sulphur. The first 16 standards were commercially available standards. Since 2008, there have been 14 standards used, all matrix-matched.

Data suggests that during the period between 2007 and 2012 there was a positive bias of between 5 and 20% in sulphide sulphur analysis conducted at Lihir laboratory data acquisition compared to standards reference materials. This suggests the Lihir method during this period reflects a total sulphur assay rather than the sulphide sulphur of the certified reference materials. In 2013 alternative sulphide sulphur techniques were introduced at Lihir which have improved the method accuracy. A further sulphide sulphur methodology improvement was implemented in 2016, with the installation of the Leco Infrared combustion analytical equipment.

Verification of sampling and assaying All data and interpretative inputs to Mineral Resource estimates are checked and verified in accordance with a range of Newcrest standard operating procedures. Procedures were also in place for all historical drilling programs at Lihir. Diamond drill core samples are processed in-house using a dedicated core processing facility, sample preparation and analytical laboratory. All resource logging data is automatically uploaded to the resource database via logging notebook computers. Newcrest employs a centralised resource drill hole database team to check, verify and validate new data and to ensure the integrity of the total resource database. Day-to-day management of the resource data is undertaken by the database administrator on site using the acQuire database system. Prior to resource estimation a centralised resource team conducts further data checks to ensure data integrity prior to estimation.

Regular internal and external reviews of all geological and Mineral Resource estimation processes are conducted to check the quality and integrity of these procedures. No adjustments have been made to assay data.

Location of data points The grid applied is a local Mine Grid that has it based on AMG Zone 56.

The original topography surface is a Light Detection and Ranging (LIDAR) surface created pre-mining. Mining activities are surveyed each month and incorporated into a topographic surface model for depletion purposes.

All completed drill hole collars are surveyed by the mine surveyors.

A variety of methods have been used to measure down hole deviation (dip and azimuth), including conventional borehole camera, electronic single shot and gyroscopic methods. The majority of the holes have been surveyed using conventional borehole camera methods.

Data spacing and distribution Historical drilling has been nominally on 35m eastings, but noting the orebody is generally insensitive to drill orientation due to complex mineralisation events.

The Mineral Resource has been classified into Indicated and Inferred Mineral Resource after assessing the following factors: drill hole spacing (only areas drilled to 70m x70m drill density have been classified as Indicated Resource), style of mineralisation and geological continuity, data quality and associated QA/QC, grade continuity and proposed mining selectivity and scale of mining. Refer Section 3 Resource Classification for further details.

The data spacing and distribution is sufficient to establish geological and grade continuity appropriate for Mineral Resource estimation and classification and supported by historical reconciliation with actual production results.
Samples for estimation purposes have been taken, but no physical compositing of samples has occurred during the analysis process.

Orientation of data in relation to geological structure Gold mineralisation in the Luise Caldera is hosted within volcanics, intrusives, and breccias which have undergone extensive alteration. Two major alteration episodes have been identified which have destroyed much of the original host rock lithologies, and due to this an “ore type” classification has been developed based largely upon various combinations of alteration, hardness, the degree of brecciation and/or leaching of matrix material, and the presence of late stage anhydrite veining. The deposit is generally sub-horizontal.

The nature of the mineralisation distribution is such that it is insensitive to drill orientation with a wide variety of orientations having been used. Diamond holes prior to 2002 are predominantly vertical, with angled holes used subsequently to define the Mineral Resource. RC holes completed prior to 2002 used both vertical and angled holes.

Sample security Samples were transported from drill site to core shed and to site laboratory, all within the operational security zone of the mine. Sample dispatches are reconciled against Laboratory samples received and discrepancies reconciled by geology staff.
Audits or reviews An independent review of assaying and QAQC in September 2012 concluded: “The historic assay bias for gold has now been rectified at Lihir, sulphur from sulphide has not been assayed correctly at Lihir laboratory during some stages of the life of operation. Assaying precision for gold is considered consistent with industry standards but lacking for sulphide sulphur. Overall the quality of the Lihir laboratory is now well controlled.”

Section 2: Reporting of Exploration Results

Criteria Commentary
Mineral tenement and land tenure status Mining and ore processing operations at Lihir are conducted pursuant to a mining development contract with the State of Papua New Guinea and the related special mining lease, and a series of granted mining leases, exploration licenses, leases for mining purposes and mining easements, and associated environmental and other approvals. The granted tenements and permits cover all infrastructure in the immediate vicinity of the mine site, including the open pit, accommodation, plant site, power station, waste-rock and tailings disposal, and bore fields. All infrastructure is in place for the continued operation of Lihir.

Current tenements granted under the PNG Mining Act comprise Special Mining Lease (SML) 6, two granted Mining Leases (MLs) and one granted Exploration Licence (EL), plus a number of miscellaneous mining purpose and easement leases. The total area under lease/licence is approximately 250 km2. The Mineral Resource lies entirely within SML 6. The registered holder for all tenure is Lihir Gold Limited, a wholly-owned subsidiary of Newcrest Mining Limited since late 2010. SML 6 expires 16 March 2035 and EL485 expired on 31 March 2020. Process for a new renewal from 1 April 2020 to 31 March 2022 was delayed by COVID-19 restrictions and will be lodged for EL485. The two MLs are current to July 2025.

Exploration done by other parties The first systematic mineral exploration in the area was by the PNG Bureau of Mineral Resources and the Geological Survey of PNG between 1969 and 1974. In their report (which was released in 1982), it detailed the hydrothermal alteration and thermal activity on Lihir Island and suggested that it was a favourable geologic environment for epithermal gold mineralisation.

The Ladolam gold deposit was initially discovered in 1982 by joint venture between Kennecott Exploration and Niugini Mining. A feasibility study was completed by Kennecott Mining in March 1992. In the mid 1990’s a joint venture was formed between Kennecott Mining and Rio Tinto. Lihir Gold Limited (LGL) was subsequently formed to hold the Mining Development Contract, the Special Mining Lease and associated tenure. Mining operations commenced at Lihir in 1997.

In 2005 Rio Tinto sold its interest in LGL, then, in late 2010, Newcrest Mining Limited acquired LGL by scheme of arrangement.

Geology Exploration has identified several adjacent and partly overlapping mineral deposits in the Luise Caldera, which are collectively called the Ladolam Deposit. The principal component deposits are called Lienetz, Minifie, Coastal and Kapit. Gold mineralisation in the Luise Caldera is contained in a hydrothermally-altered porphyry gold system with the gold hosted in volcanic, intrusive and breccias within the caldera. Two major alteration episodes have been identified which have destroyed much of the original host rock lithologies, and due to this an “ore type” classification has been developed based largely upon various combinations of alteration, hardness, the degree of brecciation and/or leaching of matrix material, and the presence of late stage anhydrite veining. The majority of the gold is contained in sulphides.

The limits of the mineralisation have not been completely defined and the deposit remains are open at depth, along strike and to the east (currently limited by the Pacific Ocean).

Drill hole Information No exploration has been reported in this release, therefore there is no drill hole information to report. This section is not relevant to this report on Ore Reserves and Mineral Resources.

Comments relating to drill hole information relevant to the Mineral Resource estimate can be found in Section 1 – “Sampling techniques”, “Drilling techniques” and “Drill sample recovery”.

Data aggregation methods No exploration has been reported in this release, therefore there are no drill hole intercepts to report. This section is not relevant to this report on Ore Reserves and Mineral Resources.

Comments relating to data aggregation methods relevant to the Mineral Resource estimate can be found in Section 1 – “Sampling techniques”, “Drilling techniques” and “Drill sample recovery”.

Relationship between mineralisation widths and intercept lengths No exploration has been reported in this release, therefore there are no relationships between mineralisation widths and intercept lengths to report. This section is not relevant to this report on Ore Reserves and Mineral Resources.
Diagrams No exploration has been reported in this release; therefore no exploration diagrams have been produced. This section is not relevant to this report on Ore Reserves and Mineral Resources.
Balanced reporting No exploration has been reported in this release, therefore there are no results to report. This section is not relevant to this report on Ore Reserves and Mineral Resources.
Other substantive exploration data Previously reported drilling results have confirmed the extension of geological and grade continuity beyond the current Mineral Resource seaward constraint.
Further work A concept study of mining beyond the current seaward constraint of the Mineral Resource is required to assess the reasonable prospects for eventual economic extraction of identified mineralisation outside the current Mineral Resource seaward constraint.

Section 3: Estimation and Reporting of Mineral Resources

Criteria Commentary
Database integrity Data is stored in a SQL Server database known as acQuire. Assay and geological data are electronically loaded into acQuire and the database is replicated in Newcrest’s centralized database system. Regular reviews of data quality are conducted by site and corporate teams prior to resource estimation, in addition to external reviews.
Site visits The Competent Person for the Lihir Mineral Resource is part of the operational management team for Lihir Mine.
Geological interpretation Gold mineralisation in the Luise Caldera is hosted within volcanics, intrusives, and breccias which have undergone extensive alteration. Two major alteration episodes have been identified; an earlier and deeper “porphyry style” event resulting in potassic alteration grading laterally into propylitic alteration, and a later and higher level epithermal event producing argillic, advanced argillic, phyllic, and lower temperature potassic alteration. This intensive alteration has destroyed much of the original host rock lithologies, and due to this an “ore type” classification has been developed based essentially upon various combinations of alteration, hardness, the degree of brecciation and/or leaching of matrix material, and the presence of late stage anhydrite veining. The ore types are roughly sub-horizontal in occurrence and form a fairly consistent vertical sequence of clay-rich rock, grading into white mica-feldspar rock, then feldspar-biotite and, at depth, into feldspar-biotite-anhydrite rock. Within and at the boundaries of the ore types, geological structure is also a major influence on the localization of higher gold grades in the orebodies.
Dimension The maximum extent of the Mineral Resource is 3km x 1km x 350m. The deposit is generally sub-horizontal with the reporting of the Mineral Resource extent limited by a seaward constraint. An exploration target known as Kapit North East is a seaward extension outside the Mineral Resource.
Estimation and modelling techniques The Lihir resource estimate contains estimates for gold, arsenic, silver, copper, carbonate, molybdenum and sulphide sulphur. Gold is the primary economic metal with sulphur and carbonate estimates required for autoclave feed management. Estimates of minor elements are required to assist with overall plant performance management.

The estimation for each element was undertaken using the non-linear estimation method of Localised Uniform Conditioning (LUC) and is based on an underlying ‘diffusion’ model, where, in general, grade tends to trend from lower to higher values and vice versa in a relatively continuous way. Raw data was composited to 12m intervals for gold and all other elements. Uniform Conditioning (UC) was used to estimate gold and sulphide sulphur within 100x100x12m panels. The UC model was converted to a LUC model into 20m x 20m x 12m blocks that define the selective mining unit (SMU). Ordinary Kriging (OK) was used for the local estimation of density into the SMU blocks. All other elements (arsenic, silver, copper, carbonate, molybdenum and calcium) were estimated into the SMU. All elements are estimated independently of each other.

In 2017 the estimation domains were updated for geologically interpreted fault blocks as well as geometallurgical domains. These were assessed and validated using contact analysis. Nine estimation domains were used for gold (used also for sulphide sulphur, carbonate, silver, arsenic, copper and molybdenum). Top cutting of extreme values for each element was done on a domain basis by examining the histogram of data such that the top 1% samples were cut so that they contained approximately 10% or less of total metal (for example this ranged from 4 to 30 g/t for gold domains).

The resource estimate is validated via visual, geostatistical and production reconciliation methods.

The December 2017 model is the basis of the Lihir December 2020 Mineral Resource.

Moisture All tonnages are calculated and reported on a dry tonnes basis.
Cut-off parameters Lihir open pit employs a grade based cut-off, taking into account metallurgical recovery assumptions, transport costs, refining charges and royalty charges. The site operating costs include mining cost, processing cost, relevant site general and administration costs and relevant sustaining capital costs. These costs equate to a break even cut off value of US$40/t milled used to define the ultimate pit shell and a marginal cut off value of US$35/t milled or 1.0 g/t gold used to define ore and waste material within the ultimate pit shell.

The marginal site cost is based on an end of mine life low grade stockpile reclaim strategy, reducing the site activity and long term cost base. The mining cost in the marginal site cost represents the stockpile reclaim cost.

Mining factors or assumptions The Mineral Resource estimate is reported within a constraining notional pit shell. The Lihir deposit is extracted via a large Open Cut. Consequently, some aspects of the model construction reflect the proposed bulk mining method of open pit mining on 12 m benches with a 20m x 20m selective mining unit.
Metallurgical factors or assumptions Gold extraction is by pressure oxidation of ore from a combination of direct feed and flotation feed sources depending on sulphur levels. The target sulphur content in slurry to the autoclave is in the range 5-10% to ensure auto-thermal operation of the autoclave. Ore blending and flotation plant operation is undertaken in a manner to maintain feed sulphur content in this range. Metallurgical test work and operating experience at site has shown that there are four main rock /alteration domain groups identified as: Argillic Clay, Advanced Argillic, Epithermal and Porphyry.

Gold recoveries recognise float recovery differences between in-situ and stockpile material, and overall neutralisation cyanidation adsorption (NCA) recovery formulae reflect oxidation intensity.

Environmental factors or assumptions Lihir operations comprise an open pit mine, ore processing plant, and associated supporting infrastructure. Higher-grade ore is processed via pressure oxidation and carbon-in-leach cyanidation methods, with lower grade ore stockpiled for later processing. Lihir uses deep sea tailings placement (DSTP). In view of the heavy rainfall typically experienced on Niolam Island, the lack of suitable area for a tailings storage facility and the high seismicity of the region, DSTP was the preferred tailings placement method for Lihir. The plant tailings are premixed with sea water within the confines of the mining lease before being placed offshore. Baseline studies were undertaken prior to the approval by PNG environmental authorities and commencement of the DSTP. Regular monitoring is undertaken to verify the operational performance of the system and is subject to the regulatory criteria established by the PNG CEPA. Waste rock from the mine is either used for construction purposes or transported in barges for off-shore submarine disposal. Submarine disposal is carefully planned and controlled to achieve a continuous rill slope along the steeply dipping sea floor and to prevent uncontrolled slumping triggering a rise in water levels.

The Mineral Resource assumes the continued use of these waste management processes.

Bulk Density All bulk density measurements are carried out in accordance with site standard procedures for Specific Gravity. The physical determination of bulk density is undertaken on solid pieces of core, 10cm in length. Intervals for bulk density determination are selected according to lithology or alteration / mineralisation type (to best represent certain intervals as defined by the geologist). The measurements are performed on site (as part of the logging process), by geological assistants. Measurements are generally taken at 50m intervals down hole, or more frequently if required. This is a dry air method of analysis.

Ordinary Kriging (OK) was used for the local estimation of density into the nine geometallurgical domains.

Classification The in-situ Mineral Resource has been classified into Indicated and Inferred based on grade continuity assessments using the criteria of slope of regression (SOR) and the variogram weighted distance (WTD). For Indicated classification a guideline of SOR > 0.7 and WTD 0.65 and WTD
Audits or reviews The current Mineral Resource estimate has been externally reviewed by SRK in December 2017 and there were no issues or concerns with the Mineral Resource inputs, process and execution. SRK concluded that the Mineral Resource estimate was suitable for reporting in accordance with the requirements of the JORC Code (2012).
Discussion of relative accuracy/ confidence For an Indicated Resource it is considered reasonable for the relative uncertainty to be +/- 15% in tonnage, grade and metal (exclusive of each other, i.e., each variable has to satisfy the criteria) for an annual production volume at a 90% confidence level. Geostatistical evaluations indicate that based on the annual processing throughputs from the pits this criteria is satisfied globally within the deposit. Relative uncertainties and confidence level estimates are only considered for gold as it is the primary economic contributor.

Detailed monthly mine reconciliations have been maintained since production commenced. The mine reconciliations since 2012 confirm that the in-situ tonnage, grade and metal variances are well within the Indicated Resource relative uncertainty band, globally.

Section 4: Estimation and Reporting of Ore Reserves

Criteria Commentary
Mineral Resource Estimate for conversion to Ore Reserves A technical description of the Mineral Resource estimate that provided the basis for the December 2020 Lihir Ore Reserve estimate is presented in the preceding sections to this table.

The Ladolam gold deposit is located within the Louise Caldera, on the eastern side of Lihir Island, New Ireland Province, Papua New Guinea. Gold mineralisation in the Luise Caldera is hosted within volcanics, intrusives, and breccias that have undergone extensive alteration. The ore body is contained in a hydrothermally-altered porphyry gold system with the gold hosted in volcanic, intrusive and breccias within the caldera. The majority of the gold is contained in sulphides.

The Measured and Indicated Mineral Resources reported in the Mineral Resource report are inclusive of those Mineral Resources modified to produce the Ore Reserves Estimate herein.

Site Visits The Competent Person for the Ore Reserve estimate is an employee of Newcrest Mining Limited and at the time of Phase 14A Ore Reserve preparation was the Senior Specialist – Long Term Planning. The CP was based on site from 2015 to 2020 providing long term and strategic planning support for operations and technical studies. This experience has been used to validate technical and operating assumptions used in the preparation of this Ore Reserve estimate.
Study Status Production at Lihir commenced in 1996 and it is now a mature and stable operation with well-established mining and processing performance.
Cut-off Parameters Lihir open pit employs a grade based cut-off, taking into account gold price, metallurgical recovery assumptions and site operating costs. The site operating costs include transport and refining costs, royalty charges, mining and processing costs, relevant site general and administration costs and relevant sustaining capital costs. These costs equate to a break even cut off value of US$38/t milled used to define the ultimate pit shell and a marginal cut off value of US$33/t milled or 1.0 g/t gold used to define ore and waste material within the ultimate pit shell.

The marginal site cost is based on an end of mine life low grade stockpile reclaim strategy, reducing the site activity and long term cost base. The mining cost in the marginal site cost represents the stockpile reclaim cost.

Mining factors or assumptions Estimation of the Lihir Ore Reserve involved standard steps of pit optimisation, mine design, production scheduling and financial modelling. Factors and assumptions have been determined as part of a prefeasibility level study completed in 2020, or are based on operating experience and performance.

Current mining activity at Lihir is via conventional truck and shovel operation, with offshore barge disposal of waste rock and land based and in-pit stockpiling and reclaim of lower grade ore. The current mining activities demonstrate the appropriateness of this mining method as the basis of the Ore Reserve estimate.

Phase 14A design parameters are tabled below:

Geotechnical slope parameters are based on the detailed analysis of ground conditions and other factors which influence geotechnical performance within the Phase 14A cutback. The Phase 14A slope design parameters are also based on the assumption that a comprehensive system of soil nails, cable anchors, mesh, shotcreting and depressurisation is used to provide additional support to the final wall configuration during cutback development, and that a backfill buttress is used to provide long term support after cutback completion. The design parameters are based on current geotechnical experience and a prefeasibility level study for the cutback mining area.

The Lihir Resource Model utilises LUC to estimate block gold content. This process allows for ore dilution and recovery to be built into the resource model based on the assumption of the selective mining unit (SMU) as the block size. The SMU assumption (20m x 20m x 12m) is based on the mining fleet size and is consistent with a high mill throughput/bulk mining strategy. Due to the LUC approach adopted in the resource model no additional mining dilution or recovery factors have been applied to the Ore Reserve estimate. This assumption is supported by the actual reconciliation between resource model and mill performance at Lihir project to date being within an acceptable uncertainty range for the style of mineralisation under consideration.

The pit optimisation takes into account Inferred Mineral Resource, however only Measured and Indicated Resource is reported in the Ore Reserve estimate. The Inferred Resource represents a small portion of material within the ultimate pit design and both the design and financial model are insensitive to the exclusion of this material.

The selected mining method requires civil engineered wall support as described above to allow access to the Phase 14A orebody. The cutback design also requires mining by a fleet of small equipment owing to the narrow ramp configuration required. Allowances for these activities are included in the preparation of the Ore Reserve estimate.
A backfill buttress required for long term support of the final cutback wall prevents mining of some existing Reserves inventory.

Metallurgical factors or assumptions The Ore Reserve estimate is based on a maximum 15.5Mtpa comminution rate plant producing gold doré. Ore processing at Lihir involves the main operations of crushing, grinding, flotation, pressure oxidation, leaching and electrowinning to recover gold from relatively high-grade sulphide feed. The Lihir process plant utilises proven technology that is widely used in the gold industry for this style of mineralisation.

The ore processing facility has been operating since it was commissioned in 1996 and upgrades took place during 2011/2012. Comminution circuit operating optimisations and minor upgrades are planned to achieve a 15.5Mtpa plant capacity.

The metallurgical recovery assumption for ore feed to the autoclave is dependent on the gold and sulphide sulphur grades, and dependent on sulphur to calcium ratio and proportion of aged stockpile feed for flotation material. Overall metallurgical recovery is reconciled with historic production data, laboratory test samples for stockpiled ore and reflects a partial oxidation metallurgical operating strategy. Average life of mine gold recovery is modelled to be
81-82%.

The potential impact of the presence of low concentrations of copper on leaching efficiency and cyanide consumption has been assessed and is not considered an issue for the Ore Reserve estimate. Copper levels are generally below 500ppm, and historical performance indicates that levels below 1000ppm show no material impact.

Environmental Lihir open pit is an operating mine and has been granted an environmental permit for the mining of the Phase 14A cutback.
Infrastructure The Lihir operation is an operating mine and has the necessary infrastructure in place for its continued operation.
Costs Capital and operating costs have been determined as part of the prefeasibility study based on estimated operating costs for a drilling, shotcreting and cable bolt installation program. Reserve cost estimates are considered to be pre-feasibility level. Provision has also been made for capital expenditure required for a fleet of smaller mining equipment suited to the cutback access configuration. Life of cutback non-sustaining capital is estimated in the range of US$60-70 million.

No cost impact is expected from deleterious elements. It has therefore not been necessary to include additional costs relating to minor elements when preparing the Ore Reserve estimate.

Transport and refining charges have been developed from first principles consistent with the application and input assumptions for these costs used by the current operation. Refining charges and transport costs are estimated to average US$2.24/oz of gold.

A royalty of 2.0% of gold revenue (net of refining and transport costs) is divided between federal, provincial governments and local level governments and landowners. A mining levy of 0.5% (net of refining and transport costs) is also applied in the preparation of this reserve estimate.

Revenue factors Long term metal prices and exchange rate assumptions adopted in the December 2020 Reserve estimation process are US$1,300/oz for gold at a AUD:USD exchange rate of 0.75. These assumptions are consistent with Newcrest metal price guideline for December 2020 Ore Reserve period.
Market assessment Newcrest is a price taker and gold is sold on the open market and subject to price fluctuations. Supply and demand for gold from Lihir is not a constraint in the estimation of the Ore Reserve.
Economic The Ore Reserve has been evaluated through a financial model. All operating and capital costs as well as revenue factors stated in this document were included in the financial model. This process demonstrated the Lihir Ore Reserve to have a positive NPV.

Sensitivities have been conducted on the key input parameters of costs and recovery which confirm the estimate to be robust. The NPV range has not been provided as Newcrest considers this to be commercially sensitive information.

Social Engagement with landowners for affected blocks within the cutback footprint and the local community was undertaken through a series of meetings in conjunction with the Mineral Resources Authority (MRA). Approval for the project has been endorsed by block executives as documented in the engagement meeting minutes.

Environmental permitting for the Phase 14A Project has been assessed and approved by CEPA.

Other Lihir Gold Limited and the Lihir Open Pit are in material compliance with all legal and regulatory requirements.

Naturally occurring risks that might have a material impact upon the Lihir ore reserve are discussed in the risks section of Newcrest’s Operating and Financial Review (in the Appendix 4E and Financial Report for the year ended 30 June 2021 which is available to view at www.asx.com.au under the code “NCM” and on Newcrest’s SEDAR profile) and include the potential impacts of seismic activity.

Classification All of the in-situ Ore Reserve is currently derived from Indicated Resources. This classification is based on the density of drilling, the ore body experience and the mining method employed. The only Proved Ore Reserves derived from Measured Resources are those reported in known and quantified stockpiles.

It is the Competent Person’s view that the classifications used for the Ore Reserves are appropriate.

Audits or reviews Golder Associates Pty Ltd (Golder) was commissioned in 2020 to conduct an independent review of the Ore Reserve estimation processes and results that did not include Phase 14A.

Golder concluded that the Ore Reserve had been prepared using accepted industry practice and is considered suitable and reported in accordance with the JORC Code, 2012 Edition.

A competent independent review of the Phase 14A Ore Reserve estimate has been undertaken by Newcrest group planning with no non-compliances or material issues.

Discussion of relative accuracy/ confidence The accuracy of the estimates within this Ore Reserve is mostly determined by the order of accuracy associated with the geotechnical slope parameters, the Mineral Resource model and the cost factors used.

The Competent Person views the Lihir Ore Reserve a reasonable assessment of the global estimate.

There are many big Australian gold stocks, but these are the five top companies in the sector by market cap.

Australia is the fourth largest producer of gold worldwide, and this past year has brought ups and downs for the commodity. The precious metal hit its 2021 high point early on and fell soon after.

Lately, gold has been resting at a strong price of around US$1,800 per ounce, and it seems like it will exit the year that way. It may even be in for a serious price hike if inflationary pressures continue on their current trajectory.

Read on to learn more about Australia’s five top gold companies by market cap. All market cap and share price information was obtained on November 25, 2021, using TradingView's stock screener.


1. Newcrest Mining

Market cap: AU$19.54 billion; current share price: AU$24.14

What are the largest Australian copper companies? These five ASX copper stocks are the biggest on the exchange by market cap.

Last year, pandemic restrictions forced copper mines to shut down across the world, driving down global production and causing the 10 largest copper-mining companies to suffer dramatic losses.

But in 2021, copper hit an all-time high of US$10,700 per tonne, and stayed over US$9,000 for much of the year.

The three top copper-producing countries globally are Chile, Peru and China, with Australia coming in at number six. Still, there are plenty of untapped resources in the land down under, and Australia is making a name for itself as an up-and-coming producer of this important base metal.


Read on to learn more about the top five Australian copper companies on the ASX, ranked by market cap. All market cap and share price information was obtained on November 26, 2021, from TradingView.

1. BHP

Market cap: AU$192.56 billion; current share price: AU$38.03

BHP (ASX:BHP) is a top global producer of copper, nickel, potash, iron ore and metallurgical coal, with copper production centralised at its South Australia-based Olympic Dam mine.

The company, whose headquarters are in Melbourne, Australia, emphasises copper’s function in renewable energy systems and the metal’s critical role in reducing carbon dioxide emissions.

Recently, BHP has focused its attention on its energy assets. In late November, the company merged its oil and gas portfolio with Woodside Petroleum, a deal that was originally struck in August of the same year. On the mineral side of its operations, BHP was looking to acquire Noront Resources (TSXV:NOT,OTC Pink:NOSOF), a Canada-based nickel, copper, chrome and platinum company, but decided not to match a superior offer.

2. OZ Minerals 

Market cap: AU$8.77 billion; current share price: AU$25.70

OZ Minerals (ASX:OZL) is a South Australia-based copper-mining company founded in 2008. Its operations include the Carrapateena project, where construction was completed in 2019, and the upcoming Malu underground mine, which was commissioned in 2015.

In a November press release, OZ Minerals reported a year-to-date 5 percent increase in group ore reserve copper metal tonnes. In its third quarter results, the company reported guidance of between 120,000 and 145,000 tonnes of copper for the year.

3. Sandfire Resources

Market cap: AU$2.59 billion; current share price: AU$6.11

Sandfire Resources (ASX:SFR) owns 7,189 square kilometres in the Bryah Basin region of Western Australia, including its DeGrussa and Monty operations. Both of these are 100 percent owned and produce copper and gold.

The company released its third quarter results in October, reporting total copper production of 15,946 tonnes. Sandfire expects output of between 64,000 and 68,000 tonnes of copper in 2022.

4. 29Metals

Market cap: AU$1.29 billion; current share price: AU$2.63

Australia-based mining company 29Metals (ASX:29M) has the Golden Grove mine in Western Australia and the Capricorn copper mine in Queensland, along with several promising new growth opportunities lined up. 29Metals focuses on copper production, though it also mines for zinc, gold and silver.

According to an October release from the company, production was weaker than expected at Golden Grove during the September quarter. However, the asset's quarter-on-quarter decline of about 10 percent was largely offset by a strong performance at Capricorn.

5. Copper Mountain Mining

Market cap: AU$804.96 million; current share price: AU$3.81

Copper Mountain Mining (ASX:C6C) is a Canadian and Australian copper miner, with its flagship Copper Mountain operation in British Columbia, Canada, and its Eva and Cameron copper projects in Queensland, Australia.

In the third quarter, Copper Mountain Mining reported total output of 22.4 million pounds of copper at its Copper Mountain mine, representing a 12.1 percent quarter-over-quarter decline in production. The company still reported positive cash flow, with strong construction and exploration gains made at its Eva and Cameron projects.
