Newcrest Mining Limited – Exploration Quarterly Report – June 2022

2022-07-20 17:36:14

Exploration success continues at Brucejack, Red Chris and Havieron

At Brucejack, drilling continues to confirm the potential for resource growth at the Valley of the Kings deposit and the surrounding area with further high grade intercepts returned from the 1080 HBx Zone, the Bridge Zone and Gossan Hill North, which are all located outside the current published resource.

  • At 1080 HBx Zone, located south of the previously released 1080 East drilling results, VU-4184 returned 25.5m @ 52g/t Au from 43.5m, including 1.0m @ 1,173g/t Au from 67.5m. In addition, VU-4201 returned 28.5m @ 35g/t Au from 48m, including 1.0m @ 924g/t Au from 72m.

  • At the Bridge Zone, VU-3767 returned 36m @ 33g/t Au from 189m, including 1m @ 1,164g/t Au from 197m.

  • At Gossan Hill North, SU-768 returned 30m @ 28g/t Au from 181.5m, including 1m @ 717g/t Au from 205.5m, and 14m @ 26g/t Au from 358.5m, including 1m @ 360g/t Au from 371.5m.

At Red Chris, ongoing drilling activities at East Ridge continue to expand the footprint and confirm continuity and extensions of higher grade mineralisation.

  • An Exploration Target1 has been defined for East Ridge with ranges from a lower case of approximately 170Mt @ 0.5g/t Au & 0.5% Cu for 2.8Moz Au & 0.9Mt Cu to an upper case of approximately 300Mt @ 0.4g/t Au & 0.4% Cu for 4.3Moz Au & 1.3Mt Cu. The Exploration Target is exclusive of the current published resource and relates to the portion of the deposit that has not yet been adequately drill tested. The potential quantity and grade of the Exploration Target is conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource.

    The grades and tonnages are estimates based on continuity of mineralisation defined by exploration diamond drilling results (previously reported including relevant sections and plans) within the Redstock Intrusive with the lower range estimate in the area with a nominal drill hole spacing of 100m x 100m and the upper range estimate extended into the area with a nominal drill hole spacing of 100m x 200m.

  • RC786 returned 482m @ 0.26g/t Au & 0.43% Cu from 712m, including 32m @ 0.88g/t Au & 0.80% Cu from 948m, located 100m above RC773 (previously reported) and remains open up dip. In addition, RC789W returned 154m @ 0.46g/t Au & 0.47% Cu from 1,242m, including 10m @ 2.0g/t Au & 1.5% Cu from 1,370m, located 100 below RC773 and 100m above RC779 (both previously reported), confirming the presence of the higher grade mineralisation.

At Havieron, growth drilling continues to identify and expand high grade extensions to the mineralisation in the Eastern Breccia, South East Crescent Zone and Northern Breccia.

  • In the Eastern Breccia, HAD152W1 returned 82.3m @ 1.7g/t Au & 0.96% Cu from 1,829.2m including 15.9m @ 1.9g/t Au & 1.6% Cu from 1,853.1m. Furthermore, HAD145AW4 returned 54m @ 3.8g/t Au & 0.02% Cu from 1,854m including 19.6m @ 9.9g/t Au & 0.02% Cu from 1,854m. These intercepts support the interpretation for the North West trending Eastern Breccia corridor to host high grade sulphide dominated mineralisation.

  • At the South East Crescent HAD133W9 returned 85.8m @ 3.0g/t Au & 0.06% Cu from 1,604m. This result has extended the Crescent high grade zone by a further 100 metres to over 1,000 vertical metres (3,800m RL) of continuous high grade sulphide dominated mineralisation.

Melbourne, Australia–(Newsfile Corp. – July 20, 2022) – Newcrest (ASX: NCM) (TSX: NCM) (PNGX: NCM) Managing Director and Chief Executive Officer, Sandeep Biswas, said, “The June quarter delivered another round of excellent drilling results across our key sites, continuing our strong track record of exploration success.”

“At Brucejack, drilling continued to deliver outstanding results in all of our target zones, supporting our views of significant resource growth opportunities beyond the Valley of the Kings deposit.”

“Drilling at Red Chris continues to define the extent and continuity of higher grade mineralisation at East Ridge, and pleasingly, the system continues to remain open further to the east.”

“Havieron continues to deliver promising results, with recent intercepts extending the high grade zone in the South East Crescent, as well as expanding the higher grade footprint in the Eastern and Northern Breccia, indicating significant potential for further resource growth.”

“Overall, FY22 has been a tremendous year for exploration success and we are well placed to progress our extensive drilling programs in the new year to create additional value for our shareholders.” said Mr Biswas.

Brucejack, British Columbia, Canada(2)

The Brucejack Property hosts the Valley of the Kings (VOK) high-grade gold deposit. The VOK is characterised by multiple occurrences of higher grade mineralisation over selected intervals hosted within broader zones of stockwork and vein arrays. Growth activities are focused on both resource expansion within the existing mine area, as well as brownfields exploration activities within 4km of the mine area. Both programs continued to deliver very strong results for the period.

Resource expansion drilling during the quarter was focused on targets in the 1080 HBx Zone and Galena Hill. A total of 18,934m in 75 drill holes was completed using 3 underground drill rigs. Assay results have been received for the first two drill fans in the 1080 HBx Zone. All other assays are pending. During the quarter, final assay results were also received from the Bridge Zone Phase 1 drill program, which included 42 drill holes in 6 drill fans, totalling 8,610m.

Brownfields drilling during the quarter focused on targets in Gossan Hill South and Golden Marmot. A total of 6,746m in 17 drill holes was completed using 4 drill rigs on surface. Assay results from these drill holes are pending. During the quarter final assay results were received from the Gossan Hill North drill program, which included 50 drill holes drilled in 8 drill fans, totalling 15,045m.

At 1080 HBx Zone, assays were received for 22 drill holes, totalling 4,983m of drilling. All drill holes intersected gold mineralisation, with 12 of the 22 drill holes intersecting higher grade mineralisation, in excess of 5 grams per tonne gold. The drill program was designed to follow up on the extensions of the high-grade gold mineralisation intersected in 1080 East drill program (previously reported).

Results have identified high-grade gold mineralisation hosted in a structure oriented sub-parallel to Domain 20, which is currently being mined in the VOK. This structure extends the zone of mineralisation an additional 150m south of the previous 1080 East drilling. Gold mineralisation has now been intersected up to 225m south and 240m below the existing Mineral Resource estimate. Drilling to test the structure along strike is currently in progress.

Results for the reporting period include:

  • VU-4117
    • 63m @ 9.1g/t Au from 10.5m
    • including 1m @ 294g/t Au from 64m
    • and 1.1m @ 1,907g/t Au from 268.2m
  • VU-4184
    • 25.5m @ 52g/t Au from 43.5m
    • including 1m @ 1,173g/t Au from 67.5m
  • VU-4194
    • 31.5m @ 19g/t Au from 79.5m
    • including 1m @ 583g/t Au from 101m
  • VU-4201
    • 28.5m @ 35g/t Au from 48m
    • including 1m @ 924g/t Au from 72m

At the Bridge Zone Phase 1, assays were received for 42 drill holes, totalling 8,610m of drilling. All drill holes intersected gold mineralisation, with 14 of the 42 drill holes intersecting higher grade mineralisation, in excess of 5 grams per tonne gold. Drilling was completed to test an area 150m south of the Valley of the Kings deposit, where previous widely spaced surface drilling intersected high-grade gold mineralisation.

Results from the Bridge Zone have defined a zone of high-grade gold mineralisation over an area with dimensions of 100m wide, 250m long, and 250m high. The zone remains open to the east, up dip, and at depth. Follow up drilling is planned to test the Bridge Zone to the east, towards the Brucejack Fault, and to test the extensions at depth.

Results for the reporting period include:

  • VU-3753
    • 18m @ 48g/t Au from 34.5m
    • including 1.1m @ 775g/t Au from 49m
  • VU-3757
    • 21m @ 37g/t Au from 51m
    • including 1m @ 728g/t Au from 66.5m
  • VU-3767
    • 36m @ 33g/t Au from 189m
    • including 1m @ 1,164g/t Au from 197m

At Gossan Hill North, assays have been received for 50 drill holes, totalling 15,045m of drilling. All drill holes intersected gold mineralisation, with 9 of 50 drill holes intersecting higher grade, in excess of 5 grams per tonne gold.

Gossan Hill is part of a four-kilometre trend of highly altered rocks which outcrop from Golden Marmot in the northwest to the Bridge Zone in the southeast. Drilling identified a series of narrow east-west trending mineralisation domains. These domains extend over an area 250m wide, 300m long, and 300m high and remain open at depth. Follow up drilling is currently in progress at Gossan Hill South, located between Gossan Hill North and the West Zone.

Results for the reporting period include:

  • SU-768
    • 30m @ 28g/t Au from 181.5m
    • including 1m @ 717g/t Au from 205.5m
    • and 14m @ 26g/t Au from 358.5m
    • including 1m @ 360g/t Au from 371.5m
  • SU-793
    • 52.5m @ 14g/t Au from 18m
    • including 1m @ 491g/t Au from 21m
  • SU-812
    • 34.5m @ 12g/t Au from 133.5m
    • including 1m @ 329g/t Au from 160.43m

Approximately 54,000m of resource expansion drilling and 35,000m of brownfield exploration drilling targeting mineralisation definition and continuity are planned during calendar year 2022 with three drill rigs underground and four drill rigs on surface.

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

Red Chris, British Columbia, Canada(3)

Red Chris is a joint venture between Newcrest (70%) and Imperial Metals Corporation (30%) which is operated by Newcrest.

The Brownfield Exploration program is focused on the discovery of additional zones of higher-grade mineralisation within the Red Chris porphyry corridor, including targets outside of Newcrest’s initial Mineral Resource estimate. During the period, there were up to eight diamond drill rigs in operation. A further 30,482m of drilling has been completed from 32 drill holes, with all drill holes intersecting mineralisation (except 5 drill holes which were dedicated geotechnical holes). This contributed to a total of 265,374m of drilling from 251 drill holes since Newcrest acquired its interest in the joint venture in August 2019.

At East Ridge, located adjacent to the East Zone, drilling is ongoing with 43 holes completed and 7 in progress. The follow up drilling is being completed on a nominal 100m x 100m grid to determine the footprint and characterise the mineralisation, and to demonstrate the continuity of the higher-grade mineralisation. Drilling to date has tested a corridor 900m long and to a vertical extent of 1,000m within which zones of higher grade mineralisation have been identified.

An Exploration Target has been defined for East Ridge as described above with ranges from a lower case of approximately 170Mt @ 0.5g/t Au & 0.5% Cu for 2.8Moz Au & 0.9Mt Cu to an upper case of approximately 300Mt @ 0.4g/t Au & 0.4% Cu for 4.3Moz Au & 1.3Mt Cu. The grades and tonnages are estimates based on continuity of mineralisation defined by exploration diamond drilling results (previously reported including relevant sections and plans) within the Redstock Intrusive with the lower range estimate in the area with a nominal drill hole spacing of 100m x 100m and the upper range estimate extended into the area with a nominal drill hole spacing of 100m x 200m.

East Ridge is outside of Newcrest’s initial Mineral Resource estimate. Diamond drilling continues to define the extent and continuity of this higher grade mineralisation. A further 25 diamond drill holes are planned, at a minimum, to test and close out the target mineralisation. This program is expected to be completed by the second quarter of calendar year 2023.

Results for the reporting period include:

  • RC786
    • 482m @ 0.26g/t Au & 0.43% Cu from 712m
    • including 32m @ 0.88g/t Au & 0.80% Cu from 948m
  • RC789W
    • 154m @ 0.46g/t Au & 0.47% Cu from 1,242m
    • including 16m @ 1.5g/t Au & 1.2% Cu from 1,370m
    • including 10m @ 2.0g/t Au & 1.5% Cu from 1,370m
  • RC795
    • 92m @ 0.41g/t Au & 0.55% Cu from 1,324m
    • including 16m @ 0.59g/t Au & 0.97% Cu from 1,390m
  • RC797
    • 152m @ 0.12g/t Au & 0.41% Cu from 1,288m

Drilling continues to define the continuity of the higher grade mineralisation with holes RC786 and RC789W. RC786 returned 482m @ 0.26g/t Au & 0.43% Cu from 712m, including 32m @ 0.88g/t Au & 0.80% Cu from 948m, located 100m above RC773 (previously reported) and remains open up dip. RC789W returned 154m @ 0.46g/t Au & 0.47% Cu from 1,242m, including 10m @ 2g/t Au & 1.5% Cu from 1,370m, located 100 below RC773 and 100m above RC779 (both previously reported) and confirmed the presence of the higher grade mineralisation.

Drilling also continues to expand the strike extent of the East Ridge mineralisation within the Exploration Target, with RC793, RC795, RC797 and RC799 located along several of the eastern most sections. RC797 and RC799 extended the porphyry corridor a further 100m east of RC793 (previously reported). RC797 returned 152m @ 0.12g/t Au & 0.41% Cu from 1,288m and demonstrates the system is present and remains open further to the east.

The East Ridge mineralised corridor (>0.4g/t Au and >0.4% Cu) extends over 900m long, up to 1,000m high and 125m wide, with higher grade (>0.8g/t Au and >0.8% Cu) in several smaller pods over an area 500m high, 400m long and 100m wide.

Approximately 50,000m of growth-related drilling targeting mineralisation definition and continuity is planned for the first half of FY23 from eight drill rigs.

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

Havieron Project, Western Australia, Australia(4)

The Havieron Project is operated by Newcrest under a Joint Venture Agreement (JVA) with Greatland Gold. Newcrest holds a 70% interest in the Havieron Project and has an option to acquire an additional 5% joint venture interest. The option price for the 5% interest has been determined by an independent valuer to be US$60 million in accordance with the process under the JVA. Newcrest has 30 business days from 20 July 2022 to elect whether to exercise the option5. The JVA includes tolling principles reflecting the intention of the parties that, subject to a successful exploration program, Feasibility Study and a positive decision to mine, the resulting joint venture mineralised material will be processed at Telfer.

The Havieron Project is centred on a deep magnetic anomaly located 45km east of Telfer in the Paterson Province. The deposit is overlain by more than 420m of post mineral Permian cover. The Joint Venture commenced drilling during the June 2019 quarter and has completed 249,240m of drilling from 306 drill holes to date (excluding holes in progress, abandoned holes, or drill holes which have not been sampled).

Drilling activities in the period have produced a further 11,796m of drilling from 21 holes with up to 7 drill rigs operating during the quarter. New assay results are reported from 18 drill holes (5 from previous quarter). Of the reported holes, 11 holes returned significant assay intercepts in excess of 50 gram metres gold (Au ppm x length m).

Growth drilling targeting mineralisation definition and continuity continues to show potential for resource additions outside of the existing Inferred Mineral Resource limits, including:

  • Extension of the South East Crescent Zone Deeps below the Updated Mineral Resource – assay results reported for 2 drill holes, 1 hole awaiting assays.
  • Extensions of the Eastern Breccia including definition of identified internal higher grade zones – assay results reported for 8 drill holes, 7 holes awaiting assays.
  • Drilling is continuing to target geophysical targets outside of the main Havieron system – 2 drill holes results reported from step out drilling north and south of the Havieron system.

At the Eastern Breccia, assays for 8 holes targeting strike and depth extensions from previously reported drill holes have been received, with 7 holes awaiting assays. The Eastern Breccia is developed below the 4,100RL with a footprint of over 500m in strike, up to 200m in width, and over 250m in vertical extent. The Eastern Breccia remains open at depth. Within this zone multiple northwest trending internal higher-grade sulphide dominated domains are observed. Results for the quarter further highlight geological continuity of higher grade within the Eastern Breccia.

Results include:

  • HAD104W2
    • 51m @ 1.1g/t Au & 0.07% Cu from 1,496m
  • HAD141W2^
    • 39m @ 2.9g/t Au & 0.15% Cu from 1,824.6m
    • including 13.8m @ 7.8g/t Au & 0.15% Cu from 1,849.8m
  • HAD145AW4
    • 54m @ 3.8g/t Au & 0.02% Cu from 1,854m
    • including 19.6m @ 9.9g/t Au & 0.02% Cu from 1,854m
  • HAD152W1
    • 82.3m @ 1.7g/t Au & 0.96% Cu from 1,829.2m
    • including 15.9m @ 1.9g/t Au & 1.6% Cu from 1,853.1m.

Drill holes targeting the Eastern Breccia also provide infill drill intercepts within the Mineral Resource in the Northern Breccia and South East Crescent. These results are in line with the modelled grades in the area. For reporting completeness these infill resource intercepts are included in Appendix 3, and highlighted in the Drill data and supporting sections and diagrams.

South East Crescent Deeps growth drilling continued during the quarter targeting higher grade mineralisation at depth below the current Mineral Resource. Results were received from 2 drill holes, with 1 hole awaiting assay results. Results from HAD133W9 have extended the Crescent high grade zone by a further 100 metres to over 1,000 vertical metres (3,800m RL) of continuous high grade sulphide dominated mineralisation, however the drilling suggests tapering of the high grade mineralisation with depth. Further drilling is planned to test this potential.

Results include:

  • HAD133W9
    • 85.8m @ 3.0g/t Au & 0.06% Cu from 1,604m.
  • HAD153
    • 44.9m @ 2.5g/t Au & 0.14% Cu from 1,577.1m
    • including 25m @ 4.1g/t Au & 0.09% Cu from 1,585m.

Drilling to test geophysical targets outside of the known Havieron mineralised system, including evaluating the Havieron dolerite at multiple intervals north and south of the Havieron mineralised envelope revealed no significant intercepts from two drill holes (HAD154 & HAD155).

Ongoing drilling is planned for the Eastern Breccia, the South East Crescent Deeps and additional geophysical targets external to the Havieron mineralised footprint.

Refer to Appendix 3 for additional information and Drillhole data table for all results reported during the period.

Wilki Project, Western Australia, Australia

The Wilki Project is an exploration farm-in and joint venture with Antipa Minerals Limited (Antipa). The project area covers a strategic landholding of ~2,200km2 surrounding the Telfer operation and is adjacent to the Havieron Project. Newcrest entered into this exploration farm-in and joint venture agreement with Antipa on 11 March 2020. Newcrest currently also has a 9.9% shareholding in Antipa.

As previously highlighted, Newcrest has elected to proceed to the next stage (Stage 1) of the farm-in agreement following completion of the initial exploration expenditure commitment (A$6 million). Newcrest has the potential to earn a 51% joint venture interest in the Wilki Project through expenditure of a further A$10 million by March 2025 during Stage 1(6). As of 1 July 2022, Newcrest is now the manager and operator of the Wilki Project.

Cultural clearance activities commenced over priority areas during the period. Field programs including soil sampling and follow up drilling will be ready for execution on completion of access.

Juri Joint Venture, Western Australia, Australia

The Juri Joint Venture is a farm-in and joint venture agreement with Greatland Gold with respect to the Black Hills and Paterson Range East projects, located within the Paterson Province approximately 50km from the Telfer operation and in proximity to the Havieron Project. The joint venture covers an area of approximately 248km2. Newcrest currently has a 51% interest in the Juri Joint Venture. Under the terms of the agreement, Newcrest has the potential to earn an additional 24% joint venture interest through expenditure of a further A$17 million over three years.

Field programs have commenced, including initial drilling focused on the A27 anomaly in Black Hills region.

Tennant East, Northern Territory, Australia

The Tennant East project comprises 6 undercover targets located 200km east of Tennant Creek. These targets have been identified on the basis of coincident gravity, magnetic and induced polarisation anomalies. Scout drill testing of the Lantern and Sabertooth targets in calendar year 2021 identified narrow zones of low order pathfinder geochemistry hosted by intense chlorite-magnetite-hematite-silica-pyrrhotite altered metasediments. Follow up exploration is currently being assessed.

Nevada, USA

Notice of termination was provided to Discovery Harbour with respect to the Fortuity89 Project in Nevada. Five RC holes were completed for 1,656m testing the targets defined from mapping and geophysics.

Central Andes, Northern Chile

A geochemical survey along with detailed geological mapping was completed for three areas of the Gorbea-Mioceno-Silencio district. A total of 1,565 soil samples and 1,565 lag samples were collected. Geochemical results will be used to evaluate the potential for the project to host a High Sulphidation Epithermal style deposit.

Field activities were suspended by adverse weather conditions at the end of May 2022 and are expected to resume during the September 2022 quarter.

Northern Andes, Ecuador

The first phase of scout drilling at the Gamora Project in southeast Ecuador was completed. Work was conducted by Newcrest as the operator under an earn-in agreement with Lundin Gold, pursuant to which Newcrest can earn up to a 50% interest in eight exploration concessions. Newcrest has elected to move to Stage Two of the agreement, which includes expenditure of US$6 million over 18 months for a 25% interest. The concession area covers strategic landholdings to the north and south of Lundin Gold’s Fruta del Norte mining operation.

First phase of drilling has downgraded the initial drill target. Further drilling on additional targets will be completed in the second half of calendar year 2022.

Section 1: Sampling Techniques and Data

Criteria Commentary
Sampling techniques Core samples are obtained from core drilling. HQ diameter diamond core was drilled on a 3m run. Core was whole core sampled at 1.5m intervals except where visible gold was identified, in which case the sample was shortened to 1.0 or 0.5m.
Drilling techniques Core drilling was advanced with HQ diameter coring configuration.

Core from select inclined drill holes are oriented on 3m 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 – 25,680m).

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

All geological and geotechnical logging was conducted at the Brucejack Mine.

Digital data logging was captured, validated and stored in a GeoSpark database.

All drill cores were photographed, prior to sampling the core.

Sub-sampling techniques and sample preparation Sampling, sample preparation and quality control protocols are considered appropriate for the material being sampled.
Whole core HQ samples.

Whole core samples were collected in plastic bags together with pre-numbered sample tags and grouped into shipping bins for dispatch to the laboratory by dedicated transport. Sample lengths were typically 1.5m, and weights typically varied from 11 to 15kg, with an average weight of approximately 12.5 Kg. Sample sizes are considered appropriate for the style of mineralisation.

All drill core samples were freighted by road to the laboratory via hired transport.

Sample preparation was conducted at the independent ISO 9001 certified and ISO 17025 accredited ALS Global preparation laboratories. Samples were dried at 600C, and crushed to 90% passing 2 mm, and split to obtain up to 1 kg sub-sample, which was pulverised (using LM2) to produce a pulped product with the minimum standard of 85% passing 75μm.

Duplicate sample data are available from crush and pulp samples at a rate of approximately 1:20. Duplicate results show an acceptable level of variability for the material sampled and style of mineralisation.

Quality of assay data and laboratory tests Assaying of drill core samples was conducted at ALS in North Vancouver. All samples were assayed for 33 elements using a 4-acid digestion followed by ICP-OES determination (method ME-ICP61). Gold analyses were determined by 50g fire assay with atomic absorption finish (method Au-AA26; with trigger to Au-Gra22 50g gravimetric overlimit method at 18 ppm).

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 Geospark SQL database and verified as acceptable prior to formal use of data from analysed batches.

Laboratory quality duplicates including replicates and preparation duplicates are captured in the Geospark SQL database and assessed.

Prepared pulp splits for mineralized samples were sent to MS Analytical Labs in Langley BC for secondary lab check work by comparable Au and ICP methods to ensure agreement with original results; check pulps were prepared for 20 samples, from 5 of the Golden Marmot holes, and overall a representative 5-7% of mineralized samples for VOK drilling was sent for secondary lab checks, including North Block Phase 4 and 1080 East level drilling. Comparisons are acceptable.

Analysis of the available quality control sample assay results indicates that an acceptable level of accuracy and precision has been achieved. 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 sampling. Corresponding sample numbers matching pre-labelled sample tags are assigned to each interval.

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

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 GeoSpark database.

Assessment of reported significant assay intervals was verified by review of visible gold identified in the drill core and review 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 All collar coordinates are provided in the North American Datum (NAD83 Zone 9N).

1080 HBx and Bridge Zone: Underground drill collar locations are marked up by the survey department with spray paint, and a back site and foresight are provided to enable alignment; Drills are then aligned by the drill contractor based on the markup and sights, and a TN-14 collar Gyro is used to confirm orientation prior to drilling.

Gossan Hill North: Surface drill collar locations are marked with a stake, and a back site and fore site are provided to enable alignment. Collar locations are picked up using a Trimble 7-series differential GPS and a TN-14 collar Gyro is used to confirm orientation prior to drilling.

Topographic control is established from 2014 Lidar.

Data spacing and distribution 1080 HBx: Drill hole spacing is 15m laterally. Assays have been received for two drill fans to date, which is insufficient for estimation of a Mineral Resource.

Bridge Zone: Drill hole spacing was 20m in lateral extent within an area of 0.025km2. The current drill hole spacing does provide sufficient information for the estimation of a Mineral Resource at Bridge Zone.

Gossan Hill North: Drill hole spacing was at 40m horizontal spacing within an area of 0.75km2. The current drill hole spacing does not provide sufficient information for the estimation of a Mineral Resource.

No sample compositing is applied to samples.

Orientation of data in relation to geological structure Drill holes at 1080 HBx are oriented towards 205 in order to drill perpendicular to the broadly WNW-ESE oriented mineralization domains. Drilling at 1080 HBx intersected a mineralized structure oriented sub-parallel to Domain 20, hosted in the Eastern Promises Porphyry unit.

Drill holes at Bridge zone are oriented towards 205 in order to drill perpendicular to the broadly WNW-ESE oriented mineralization domains. Drilling at Bridge Zone interested the Bridge Zone porphyry unit.

Drill holes at Gossan Hill North are oriented towards either 160 or 340 in order to drill perpendicular to the mineralization domains which broadly strike towards 295 degrees. Drill holes at North Gossan Hill intersected shallowly dipping andesitic fragmental volcaniclastic units.

Sample security The security of samples is ensured by tracking samples from drill rig to database and by using trusted transportation services, and third party laboratories with security protocols.

Drill core was delivered from the drill rig to the Brucejack Core Facility. Geological and geotechnical logging, high resolution core photography and whole core sampling was undertaken at the Brucejack Core Facility.

Sample numbers are obtained from pre-made sample tag books, first ensuring no duplication of sample ID’s in the database. Sample tags are inserted into labelled plastic bags together with the sample, and the bagged sample secured with a zip tie.

Samples were grouped in sequence into rice bags, then placed into dedicated sample shipment bins for transport offsite. Samples are transported by road to the preparation lab where transfer of custody occurs.

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 shipments are recorded in a shipment tracking table and require offsite removal forms prior to leaving the Brucejack site. Shipping dates, Hole IDs, sample ranges, and special instructions are recorded with the dispatch of samples to the laboratory analytical services. Receiving laboratories have a workorder template of methods and duplicates by which to process the samples unless otherwise specified. Any discrepancies noted during sample login at the laboratory are communicated and addressed.

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.

Section 2: Reporting of Exploration Results

Criteria Commentary
Mineral tenement and land tenure status Brucejack comprises 346 mineral tenures including four mining leases and is 100% owned by Newcrest Mining Limited.

All obligations with respect to legislative requirements including minimum expenditure are maintained in good standing.

Exploration done by other parties Granduc, Esso, Newhawk, Lacana Mining Corp., and Silver Standard conducted exploration in the area between 1960 and 2010.

Pretium Resources acquired the Brucejack Property in 2010 and drilled the discovery hole at the Valley of the Kings in 2011. North Block and 1080 level were first drilled in 2020. Golden Marmot was previously drilled in 1988 and 2011.

Geology The Brucejack Project is located in the Stikine terrane of north-western British Columbia, 50 km north of the town of Stewart. Early Jurassic sedimentary and volcanic rocks of the Lower Hazelton Group host mineralisation. A pervasive quartz-pyrite-sericite alteration event predates the main stage of epithermal mineralisation. Gold mineralisation at Brucejack consists of electrum hosted in vein stockworks, sheeted veins, and veinlets.
Drill hole information As provided.
Data aggregation methods Significant assay intercepts are reported as length-weighted averages exceeding 0.6g/t Au greater than or equal to 10m, with less than 7.5m of consecutive internal dilution. Also reported are intervals greater than 150g/t Au. Intervals below a cutoff of 1.0gt Au were not reported as significant results. No top cuts are applied to intercept calculations.
Relationship between mineralisation widths and intercept lengths Significant assay intervals reported represent apparent widths. Insufficient geological information is available to confirm the geological model and true width of significant assay intervals.
Diagrams As provided.
Balanced reporting This is the second release of Exploration Results for this project made by Newcrest. The previous release date was 28 April 2022.

Exploration drilling programs are ongoing and further material results will be reported in subsequent Newcrest releases.

Other substantive exploration data Nil.
Further work Drilling is currently at 1080 HBx to complete the remaining 10 drill fans in the program. Surface drilling is also planned for Golden Marmot and South Gossan Hill, which is located between North Gossan Hill and the West Zone. Follow up drilling is also planned for Bridge Zone, west from the existing drilling towards the Brucejack Fault.

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 – 30,482m in 32 holes – all holes intersected mineralisation except for 5 dedicated geotechnical holes, including orientation of key geological features).

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

Magnetic susceptibility measurements were recorded every metre.

All geological and geotechnical logging was conducted at the Red Chris Mine.

Digital data logging was captured, validated and stored in an acQuire database.

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

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

Core was cut and sampled at the Red Chris Mine core processing facility. Half core samples were collected in plastic bags together with pre-numbered sample tags and grouped in wood crates for dispatch to the laboratory. Sample weights typically varied from 5 to 10kg. Sample sizes are considered appropriate for the style of mineralisation. Drill core samples were freighted by road to the laboratory.

Sample preparation was conducted at the independent ISO 9001 certified and ISO 17025 accredited Bureau Veritas Commodities Canada Ltd Laboratory, Vancouver (Bureau Veritas). Samples were dried at 650C, and crushed to 95% passing 4.75 mm, and the split to obtain up to 1kg sub-sample, which was pulverised (using LM2) to produce a pulped product with the minimum standard of 95% passing 106μm.

Duplicate samples were collected from crush and pulp samples at a rate of 1:20. Duplicate results show an acceptable level of variability for the material sampled and style of mineralisation.

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

Quality of assay data and
laboratory tests
Assaying of drill core samples was conducted at Bureau Veritas. All samples were assayed for 59 elements using a 4-acid digestion followed by ICP-AES/ICP-MS determination (method MA250). Gold analyses were determined by 50g fire assay with ICP-ES finish (method FA350). Carbon and Sulphur were determined by Leco (method TC000) and mercury using aqua regia digestion followed by ICP-ES/MS determination (method AQ200).

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

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

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

Due to the limited extent of the drilling program to date, extended quality control programs are yet to be undertaken, whereby pulped samples will be submitted to an umpire laboratory and combined with more extensive re-submission programs.

Analysis of the available quality control sample assay results indicates that an acceptable level of accuracy and precision has been achieved and the database contains no analytical data that has been numerically manipulated.

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

Verification of sampling and assaying Sampling intervals defined by the geologist are electronically assigned sample identification numbers prior to core cutting. Corresponding sample numbers matching pre-labelled sample tags are assigned to each interval.

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

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

Assessment of reported significant assay intervals was verified by re-logging of drill core intervals and assessment of high resolution core photography. The verification of significant intersections has been completed by company personnel and the Competent Person/Qualified Person.

No adjustments are made to assay data, and no twinned holes have been completed. Drilling intersects mineralisation at various angles.

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

Location of data points Drill collar locations were surveyed using a RTK GPS with GNSS with a stated accuracy of +/- 0.025m.

Drill rig alignment was attained using an electronic azimuth aligner (Reflex TN14 GYROCOMPASS). Downhole survey was collected at 9 to 30m intervals of the drill hole using single shot survey (Reflex EZ-SHOT). At the end of hole, all holes have been surveyed using a continuous gyro survey to surface (Reflex EZ-GYRO).

Topographic control is established from PhotoSat topographic data and derived digital elevation model. The topography is generally low relief to flat, with an average elevation of 1500 m, with several deep creek gullies.

All collar coordinates are provided in the North American Datum (NAD83 Zone 9).

Data spacing and distribution The drill hole spacing ranges from 100 – 200m in lateral extent within an area of 1.5km2 at the East Ridge, 1.5km2 at the East Zone, 1.5km2 at the Main Zone and 1.5km2 at the Gully Zone. An initial Mineral Resource for the East Zone, Main Zone and Gully Zone was released on 31 March 2021.
No sample compositing is applied to samples.
Orientation of data in relation to geological structure Drilling of reported drill holes RC787, RC789, RC789W, RC793, RC795, RC797 and RC799 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.

Section 2: Reporting of Exploration Results

Criteria Commentary
Mineral tenement and land tenure status Red Chris (including the GJ Property) comprises 204 mineral claims including five mining leases and is a joint venture between subsidiaries of Newcrest Mining Limited (70%) and Imperial Metals Corporation (30%). Newcrest Red Chris Mining Limited is the operator of Red Chris. In June 2022, Newcrest closed the acquisition of four early stage exploration properties from Hawkeye Gold & Diamond. The Todagin, McBride and Railway properties are expected to be added to the Red Chris Joint Venture.

Newcrest Red Chris Mining Limited and the Tahltan Nation (as represented by the Tahltan Central Government, the Tahltan Band and Iskut First Nation) signed an amended and restated updated Impact, Benefit and Co-Management Agreement (IBCA) covering Red Chris on 15 August 2019.

All obligations with respect to legislative requirements including minimum expenditure are maintained in good standing.

Exploration done by other parties Conwest Exploration Limited, Great Plains Development Co. of Canada, Silver Standard Mines Ltd, Texasgulf Canada Ltd. (formerly Ecstall Mining Limited), American Bullion Minerals Ltd and bcMetals Corporation conducted exploration in the areas between 1956 and 2006.

Imperial Metals Corporation acquired the project in 2007 and completed deeper drilling at the East and Main Zones between 2007 and 2012.

Geology The Red Chris Project is located in the Stikine terrane of north-western British Columbia, 80 km south of the town of Dease Lake.

Late Triassic sedimentary and volcanic rocks of the Stuhini Group host a series of Late Triassic to Early Jurassic (204−198 Ma) diorite to quartz monzonite stocks and dykes.

Gold and copper mineralisation at Red Chris consists of vein, disseminated and breccia sulphide typical of porphyry-style mineralisation. Mineralisation is hosted by diorite to quartz monzonite stocks and dykes. The main mineral assemblage contains well developed pyrite-chalcopyrite-bornite sulphide mineral assemblages as vein and breccia infill, and disseminations. The main mineralisation event is associated with biotite and potassium feldspar-magnetite wall rock alteration.

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

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

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

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

Logging Geological logging recorded qualitative descriptions of lithology, alteration, mineralisation, veining, and structure (for all core drilled – 10,217 m for 21 drill holes, all intersecting mineralisation), including orientation of key geological features.

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

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

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

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

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

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

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

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

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

Duplicate samples were collected from crush and pulp samples at a rate of 1:20. Duplicate results show an acceptable level of variability for the material sampled and style of mineralisation.

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

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

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

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

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

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

Analysis of the available quality control sample assay results indicates that an acceptable level of accuracy and precision has been achieved and the database contains no analytical data that has been numerically manipulated.

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

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

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

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

Assessment of reported significant assay intervals was verified by re-logging of diamond drill core intervals and assessment of high resolution core photography. The verification of significant intersections has been completed by company personnel and the Competent Person/Qualified Person.

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

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

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

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

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

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

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

Drilling intersects mineralisation at various angles.

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

Variable brecciation, alteration and sulphide mineralisation is observed with a footprint with dimensions of 650m x 350m trending in a north west orientation and over 1000m in vertical extent below cover.

The subvertical southeast high grade arcuate crescent sulphide zone has an average thickness of 20m and has been defined over a strike length of up to 550m, and extended to over 700m in vertical extent below cover.

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

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

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

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

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

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

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

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

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

Section 2: Reporting of Exploration Results

Criteria Commentary
Mineral tenement and land tenure status The Havieron Project is entirely contained within mining tenement M45/1287, which is jointly owned by Greatland Pty Ltd and Newcrest Operations Limited. Newcrest has entered into a Joint Venture Agreement (effective 30 November 2020) and Farm-In Agreement (effective 12 March 2019) with Greatland Pty Ltd and Greatland Gold plc. Newcrest is the Manager of the Havieron Project and holds a 70% interest in the Havieron Project with an option to acquire an additional 5% joint venture interest. The option price for the 5% interest has been determined by an independent valuer to be US$60 million in accordance with the process under the joint venture agreement. Newcrest has 30 business days from 20 July 2022 to elect whether to exercise the option.

Newcrest and Jamukurnu-Yapalikurnu Aboriginal Corporation (formerly WDLAC) are parties to an ILUA which relates to the use of native title land for Newcrest’s current operations at Telfer and its activities within a 60km 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 part of the exploration tenement on which the Havieron Project is based) and was granted on 10 September 2020.

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 and copper grades are reported to two significant figures, the downhole lengths are rounded to 0.1m which may cause some apparent discrepancies in interval widths. Samples are from core drilling which is PQ, HQ or NQ in diameter. Core is photographed and logged by the geology team before being cut. Half core PQ, HQ and NQ samples are prepared for assay and the remaining material is retained in the core farm for future reference. Each assay batch is submitted with duplicates and standards to monitor laboratory quality. Total depth (end of hole) is rounded to one decimal place for reporting purposes. Collars denoted with a * show partial results, with further significant assays to be reported in subsequent exploration updates.
