Melbourne, Australia--(Newsfile Corp. - October 11, 2021) - Newcrest Mining Limited (ASX: NCM) (TSX: NCM) (PNGX: NCM) is pleased to announce that the Havieron Pre-Feasibility Study Stage 1 (the Study) has been completed and the Newcrest Board has approved the progression of the Study to the Feasibility Stage.

The Havieron Project (the Project) is located 45km east of Newcrest's existing Telfer operation and is a high grade, low capital intensity project with significant expansion potential. Newcrest has adopted a staged approach to the evaluation and development of Havieron aiming to deliver early production and cash flows from the project while work continues to define potential resource additions and assess growth targets. The benefit of existing processing capacity at Telfer and ongoing definitional drilling highlights the clear potential for a larger scale operation that will be further assessed during the Feasibility Stage.

Newcrest Managing Director and Chief Executive Officer, Sandeep Biswas, said "It is an incredible achievement that, within two years of starting the Havieron drilling program, we have been able to deliver this significant project milestone and demonstrate financial returns that comfortably exceed our hurdle rate, even in this first stage. The Pre-Feasibility Study underpins an initial Ore Reserve estimate for the upper section of the South East Crescent Zone which increases our confidence in achieving first production in FY24 and triggers our entitlement to a cumulative 70% Joint Venture interest."

"We believe that this is just the first stage of a bright and profitable future for Havieron. Our extensive drilling program continues to assess the extent of the South East Crescent Zone and further test the Northern and Eastern Breccia for mineralisation which may be suitable for bulk mining methods. We have recently delivered several new and exciting high grade intercepts which extend the high grade mineralisation beneath the initial Mineral Resource estimate and highlights the potential for further resource growth".

"Notably, the Study assumes that Havieron is the sole ore feed for the Telfer plant and does not assume any potential upside from the extension of Telfer's mine life beyond FY24. We continue to assess the potential for further open pit and underground opportunities at Telfer to extend its life and supplement production from Havieron in FY24 and beyond" said Mr Biswas.

The Havieron Project is located on the traditional lands of the Martu people who hold exclusive possession native title rights to 130,000km² of country in the Western Desert. The Indigenous Land Use Agreement with Western Desert Land Aboriginal Corporation, centred on the Telfer mine, extends to the Havieron project.

The Project is operated by Newcrest under a Joint Venture Agreement with Greatland Gold plc (Greatland Gold). Completion of this Pre-Feasibility Study triggers Newcrest's entitlement to an additional 10% interest in the Joint Venture for a cumulative 70% Joint Venture interest. Newcrest has an option to acquire an additional 5% Joint Venture interest for fair market value, exercisable during the 12 months from 12 December 2021.

Key milestones⁵

Potential Exploration Upside

The Study considers only the Indicated Mineral Resource, which is a small portion of the existing resource inventory and excludes Inferred Mineral Resources. The Havieron Project has significant additional growth potential, including:

• Mineralisation open at depth and along strike:
  • Extension of the SE Crescent Zone below the current Mineral Resource, where increasing grade and thickness of mineralisation has been observed in recent drilling
• Expansion of multiple higher-grade targets within the main Havieron NW corridor, including the Northern Breccia and NW Pod
• Potential for additional NW trending corridors including the Eastern Breccia; and
• Potential to discover additional mineralisation centres (at Havieron North, Zipa and Meco).

In addition to the active testing of the above higher-grade targets, drilling continues in the northern and eastern breccia corridors to assess the bulk mining potential.

Havieron Feasibility Study⁵

The Havieron Feasibility Study is expected to be completed in the December 2022 Quarter and the study scope is expected to include:

• Completion of a further infill drilling program by end of CY21 to increase the Indicated Mineral Resource base for potential Ore Reserve expansion
• Completion of the growth drill program immediately below the Crescent Zone for potential Mineral Resource expansion
• Further investigation and optimisation of the Sub-Level Open Stoping (SLOS) design and sequence to include additional Inferred Mineral Resources that are currently being drilled with the aim of increasing resource confidence that Indicated Mineral Resources can support production rates of 3Mtpa or higher
• Initial assessment of future development options with further resource growth in the Northern and Eastern Breccia including evaluation of alternative, lower cost, mining methods.

Project Details

The Havieron Project is centred on a deep magnetic anomaly 45km east of Telfer in the Paterson Province on the traditional lands of the Martu people. The target is overlain by approximately 420m of post mineralisation Permian cover. Newcrest commenced drilling during mid-2019 and has progressively increased its drilling activities with up to eight drill rigs now in operation.

The Martu people and the Western Desert Land Aboriginal Corporation (WDLAC) are key project stakeholders. The Martu hold exclusive possession native title rights and interests over more than 130,000 km² of land, including to all points around the Telfer mine and Havieron Project. The Indigenous Land Use Agreement (ILUA) with WDLAC, centred on the Telfer mine, extends to the Havieron project.

The Project has received the necessary regulatory approvals for the construction of a box cut, exploration decline and associated surface infrastructure, with these works formally commencing in January 2021. The Study has assessed the next stage of the Project which comprises the underground and surface development to establish the initial mining area at Havieron and ore processing modifications at Telfer.

Mineralisation of gold and copper in the current Resource Model are within the South East (SE) Crescent and the Breccia zones. High grade gold mineralisation is associated with a massive sulphide zone termed the Crescent Zone which occurs on the margin of the Breccia zones. The Crescent Zone is characterised by a series of massive to
semi-massive sulphide replacement units that have a subvertical dip and are best developed on the SE of the system forming as arcuate, crescent like geometry. The Breccias are still being defined through exploration drilling and
early-stage evaluations will be completed to test the potential to develop additional mining fronts and utilise bulk mining methods.

The SE Crescent Zone is 5-40m wide, extending 550m in length in unfolded section from the basement contact and defined over 900m vertically, tapering to ~300m in length and open at that depth. The SE Crescent Zone has been the focus of drilling and has been infilled to a nominal drill spacing of 50-100m laterally (with at least part being infilled to a 50m x 50m spacing to satisfy the requirements for an Indicated Mineral Resource), and 100m vertically.

The Study assessed mining production methods including SLOS with mining rates of 2Mtpa to 3Mtpa and caving options up to 6Mtpa. Surface infrastructure studies were focused on the transportation of ore back to the Telfer processing plant with a range of options considered in early-stage evaluations including conveyor, rail, pipeline and truck haulage, with the latter adopted for the Ore Reserve case. Processing studies evaluated a modified Telfer process plant to accommodate the Havieron ore.

The initial Ore Reserve case is based on a ~2Mtpa production rate from SLOS mining method limited to the Indicated Mineral Resources within the SE Crescent Zone. The Study demonstrates the potential to expand the Project and increase the mining rate to 3Mtpa or more based on the conversion of the current Inferred Mineral Resources and additional potential Mineral Resource growth from immediately below the Crescent Zone (Figure 2) as seen in recent drill results (refer to Section titled "Potential Exploration Growth" on Page 14 for a summary of drill results).

Indicative Production Profile (100% terms)^1,2

The Ore Reserve Case for the Study is based on the currently defined Indicated Mineral Resource estimate which incorporates a ~2Mtpa underground SLOS operation with an expected mine life of 9 years. Ore will be transported in trucks along a new 55km long haul road to the modified processing plant at the Telfer mine and tailings deposited at Telfer's existing tailings storage facility (TSF).

Multiple stope priority runs were conducted to determine the optimal sequence which maximises the number of years at peak production while reducing and compressing the production tail as much as practical. The production rate of ~2Mtpa for the Havieron SLOS was determined by maximising the steady state production of the sequence.

The indicative gold and copper production profiles are shown in the figures below:

Indicative Havieron Mine Production Profile^1,2

Estimated Development Capital Profile (100% terms)^1,3,7,8

The capital profile for the Project contemplates a ~2Mtpa SLOS operation. Having now completed the Study, Greatland is obliged to fund 30% of all project expenditure going forward and Newcrest is obliged to fund 70%. This funding split will adjust to 25% Greatland and 75% Newcrest if Newcrest exercises its option to acquire the additional 5% interest.

Metal Price and Exchange Rate Sensitivity Analysis^1,2,3

The actual IRR of the Project will vary according to the gold and copper prices realised. Base case assumptions include a gold price of US$1,500/oz, copper price of US$3.30/lb, and an AUD:USD exchange rate of 0.75.

The table below outlines how the estimated Base Case Project IRR of 16% varies using different price assumptions:

Mine Development and Sequence

SLOS is a large-scale open stoping method that is conducted over multiple levels at once. Once the stope has been mined out it is backfilled with paste to maintain the overall stability of the opening and enable mining of adjacent stopes. This method is typically applied to strong orebodies that require minimal support and are surrounded by strong country rock, such as the Havieron deposit. Stopes are mined in a checkerboard fashion with all primary stopes first, followed by the intermediate secondary stopes. The mining sequence is top down overall, divided into a number of different lifts separated by horizontal sill levels which are recovered after the upper and lower level have been mined and filled.

A sub-level spacing of 50m with sill drill levels located 20m below each mining front was selected. Some sub-level spacings are increased to 60m to accommodate the inclusion of ore and minimising additional level development. The design consists of nine semi-independent mining sequences, based on both horizontal and vertical mining fronts. The horizontal fronts are determined by the orebody orientations as outlined in Figure 4.

Infrastructure

The Study contemplates the transport of ore from the mine to Telfer via road trains on an all-weather unsealed road. The road has been designed to withstand a 1-in-a-100-year flood event and maintain access to Havieron.

Power will be supplied to Havieron from Telfer's existing gas power station via a 66 kilovolt (kV) overhead line running parallel to the nominated haul road corridor. Further opportunities to replace this with non-fossil fuel power generation as part of Newcrest's emission reduction program will be evaluated as part of the Feasibility Study.

Telfer currently operates two processing trains with a total capacity of ~22Mtpa. The Havieron ore is expected to be processed through a modified Telfer Processing Plant which will operate a single train at 6Mtpa rate on a campaign basis. The Plant modifications are expected to include magnetic separation within the flotation circuit to reduce the amount of pyrrhotite in the final Cu Concentrate and a Carbon in Pulp (CIP) circuit on the flotation tail and cyanide detoxification circuit. The expected cost of the plant modifications is included in the $529 million project capital estimate^1,3,7,8 . A single train operation also provides optionality if higher mining rates are achieved from Havieron or through the extension of Telfer's current mine life (i.e. Telfer ore can be run through the other train with the existing flowsheet). Tailings from ore processed will be deposited at the existing Telfer TSF.

Joint Venture Agreement

The Project is operated by Newcrest under a Joint Venture Agreement with Greatland. Pursuant to the farm-in and joint venture arrangements, the completion of the Study triggers Newcrest's entitlement to an additional interest in the joint venture for a cumulative 70% joint venture interest and the option to acquire an additional 5% joint venture interest at fair market value. The option period commences on 12 December 2021 and will run for 12 months.

The Joint Venture Agreement includes tolling principles reflecting the intention of the parties that, subject to the outcome of the Feasibility Study and a positive decision to mine, the Havieron mineralised material will be processed at Telfer pursuant to a Tolling Agreement. The tolling principles include an agreed processing fee formula, which includes charges for capital costs incurred in upgrading the Telfer facilities, as required, to treat Havieron ore in the tolling process. The Telfer infrastructure is not included in the scope of the Joint Venture assets, so the Tolling Agreement is the route by which Greatland will bear the capital, operating and haulage costs involved with processing Havieron ore.

Mineral Resource Estimate^[12]

The updated Mineral Resource is estimated to contain an Indicated Mineral Resource of 1.9 million ounces of gold and 0.10 million tonnes of copper and an Inferred Mineral Resource of 1.7 million ounces of gold and 0.07 million tonnes of copper. This Mineral Resource estimate is based on drilling completed by February 2021.

Since the initial Mineral Resource estimate an additional 45 drill holes were completed between November 2020 and February 2021, primarily as infill drilling to increase the resource confidence of the Crescent Zone, that transferred 1.9 million ounces of gold and 0.10 million tonnes of copper from Inferred Mineral Resources to Indicated Mineral Resources.

Mineral Resource estimate tabulation for the Havieron Deposit:

Indicated Gold Mineral Resource (100%):

Inferred Gold Mineral Resource (100%):

Indicated Copper Mineral Resource (100%):

Inferred Copper Mineral Resource (100%):

The Havieron Mineral Resource estimate is reported as an Indicated Mineral Resource and Inferred Mineral Resource in accordance with the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves 2012 (JORC Code). Refer to details in Appendix 1 for information relating to data collection and resource estimation. There are no material differences between the definitions of Indicated or Inferred Mineral Resources under the 2014 CIM Definition Standards for Mineral Resources and Mineral Reserves and the equivalent definitions in the JORC Code. Mineral Resources are reported inclusive of Ore Reserves. Mineral Resources that are not Ore Reserves do not have demonstrated economic viability.

Drilling has outlined an ovoid shaped zone of variable brecciation, alteration and sulphide mineralisation with dimensions of approximately 650m x 350m x 1000m trending in a north west orientation below 420m of Permian cover.

Gold and copper mineralisation at Havieron consists of breccia, vein and massive sulphide replacement gold and copper mineralisation typical of intrusion-related 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 Indicated Mineral Resource estimate is restricted to the South East Crescent Zone only, with the Inferred Mineral Resource estimate comprised of some part of the South East Crescent Zone, the Breccia Zones, and a portion of the Northern Breccia Zones to an RL of 4060m (~750m below the unconformity) where drill data provides sufficient support to define an appropriate level of geological control and statistical confidence.

Ordinary Kriging of 5m composites of gold and copper was undertaken into 10m x 10m x 10m blocks for Crescent and 20m x 20m x 20m blocks for Breccia and re-blocked into 5m x 5m x 5m blocks. The resource model was domained utilising the geological unit of the Crescent Zone, the Calcite Cemented Breccia, Actinolite Cemented Breccia and Crackle Breccia. Hard boundaries were used between the Crescent Zone and the Breccia zones with semi soft boundaries used between the Breccia zones. Kriging Neighbourhood Analysis was used to define the search neighbourhood for gold and copper. Gold and copper were estimated independently of each other. Composite copper and gold grades were capped prior to estimation. The resource estimation is based entirely on interpolation. The resource model was validated via visual, statistical, and geostatistical methods.

Reasonable prospects for eventual economic extraction have been assessed through ongoing mining and processing studies which suggest that selective underground mining would be appropriate for exploitation of the Crescent Zone. The Indicated and Inferred Mineral Resource estimate has been constrained using appropriate drill hole data spacing parameters and geological control. The Indicated Mineral Resource estimate is reported based on the A$100/t Net Smelter Return (NSR) value cut-off and the average weighted distance of 45 metres within the SE Crescent Zone which assumes selective underground mining. The Inferred Mineral Resource estimate is reported within an A$50/t NSR value shell with no internal selectivity, which assumes bulk mining and therefore includes internal waste. The NSR uses metals prices of US$1,400/oz Au and US$3.40/lb Cu, domain-specific metallurgical recoveries of 84-94% for Au and 82-92% for Cu, a AUD:USD exchange rate of 0.75, as well as treatment and refining costs, payables and royalties, similar to those at Telfer.

Ore Reserve Estimate¹³

The Havieron Ore Reserve estimate is outlined below and reported as a Probable Ore Reserve in accordance with the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves 2012 (JORC Code). Refer to details in Appendix 1 for information relating to Ore Reserve estimation. There are no material differences between the definitions of Probable Ore Reserves under the JORC Code and the equivalent definitions under the 2014 CIM Definition Standards for Mineral Resources and Mineral Reserves.

A summary of the material assumptions is outlined below and included in the Appendix (JORC Table 1 - Section 4).

A Pre-Feasibility level study has been completed which provides supporting basis for this Ore Reserve estimate. The Havieron Pre-Feasibility Study (on which this Ore Reserve statement is based) defined a SLOS mining method with paste fill and truck ore haulage at a 2Mtpa mining rate. Metallurgical test-work has been executed on the Havieron deposit during the Pre-Feasibility Study and in preceding studies. The test-work undertaken is of an adequate level to ensure an appropriate representation of metallurgical characterisation and the derivation of corresponding metallurgical recovery factors.

Havieron is a greenfield site and currently does not have infrastructure to support mining operations. Major infrastructure requirements are included in the Pre-Feasibility Study capital cost estimates, which are based on multiple market prices across all technical disciplines. Provision has been made for capital expenditure requirements for new equipment, infrastructure and replacement of infrastructure and equipment during the life of the mine is based on the study. A contingency has also been factored into the capital cost estimate consistent with the level of accuracy of the study.

The operating cost estimate has been built up from a combination of existing Telfer site costs scaled for the Havieron material throughput rate, first principles cost modelling and quotations where practicable.

The Probable Ore Reserve is based on Indicated Mineral Resources and diluting material. No Measured Mineral Resources are stated for this deposit. This classification is based on geological confidence as a function of continuity and complexity of geological features; data spacing and distribution and estimation quality parameters including distance to informing samples for block grade estimation.

Underground mining at Havieron is planned to be undertaken using a SLOS mining method at a 2Mtpa mining rate. The Pre-Feasibility Study has been prepared on the basis of:

• decline, accesses to the levels, ore passes, ventilation raises and other underground excavations
• SLOS stopes with paste fill
• paste fill plant and underground distribution system
• ventilation shafts, fans, regulators and refrigeration equipment
• dewatering, electrical and other service equipment
• truck haulage of ore to surface via the access decline

The following Modifying Factors have been applied to all mining shapes to accurately represent the expected mined tonnes and grades:

• Dilution factors for overbreak in primary, secondary and tertiary stopes (average 9%) consisting of waste (average 6%) and stope paste (average 3%);
• Dilution included at zero grade; and
• Mining recovery factor of 97.5%

Of the total Ore Reserve approximately 0.6Mt of ore is Inferred Mineral Resource as dilution. This material contains 2% of the gold metal and 1.6% of the copper metal in the Ore Reserve and does not have a material impact upon the estimate. As this is dilution material associated with the SLOS mining method, it has been incorporated into the Ore Reserve estimate.

Havieron ore will be processed on a campaign basis through the Telfer Train 2 Treatment Plant circuit at a throughput of approximately 2Mtpa. Metal recovery will be through conventional flotation to produce a copper/gold concentrate and doré through a newly installed flotation tails leach circuit. The technology associated with the ore processing is conventional and the flowsheet is similar to that utilised by other operations.

Metallurgical recovery assumptions are based on detailed analysis and laboratory flotation and leach test work completed on 38 variability samples during the Havieron Concept (2020) and Pre-Feasibility (2021) studies with good spatial coverage of the SE Crescent Zone. Of the 38 samples, 8 samples are located in the breccia zones and
30 samples are located in the SE Crescent Zone, of which 21 samples are located within the SE Crescent Zone Indicated Mineral Resources. Based on these samples metallurgical recoveries for gold are anticipated to average approximately 88% and recoveries of copper are expected to average approximately 84% throughout the life of the project.

Bismuth is the key deleterious element for the gold/copper concentrate product with smelter penalties incurred on the basis of bismuth content. The impact of bismuth in concentrate will be managed by mine sequencing and concentrate blending.

The Havieron Ore Reserve employs a value based cut-off determined from the Net Smelter Return (NSR) value equal to the site operating cost included within the Pre-Feasibility Study. The NSR calculation takes into account revenue factors, metallurgical recovery assumptions, transport costs, refining charges, and royalty charges.

The site operating costs include mining cost, processing cost, relevant site general & administration costs and relevant sustaining capital costs. These costs equate to a break even cut off value of approximately A$130/t milled, and a marginal cut off value of approximately A$115/t milled.

Estimation of the Havieron Ore Reserve involved standard steps of mine optimisation, mine design, production scheduling and financial modelling. Factors and assumptions have been based on benchmarked performance from similar SLOS 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 Havieron Ore Reserve has a positive NPV. Sensitivities were conducted on the key input parameters including commodity prices, capital and operating costs, ore grade, mined tonnes and mining rate, exchange rate and metallurgical recoveries confirming the estimate to be robust.

A staged approach for approvals is being undertaken with Phase 1 currently approved which has allowed the development of the boxcut, decline and service corridor. These approvals also allow for a waste rock dump, evaporation ponds and supporting infrastructure such as offices and workshops.

Phase 2 approvals will consist of a SLOS underground mine, permanent infrastructure corridor, associated infrastructure and changes to Telfer approvals to accept Havieron tailings in existing tailings storage facilities. The approval strategy for Phase 2 consists of both Commonwealth and State level approvals with engagement well advanced with all regulatory bodies. The timelines outlined in the Pre-Feasibility Study are considered achievable.

A Mining Lease has been granted over the orebody, and miscellaneous leases granted along the existing service corridor. For Phase 2 approvals an application will be made for an additional miscellaneous lease to secure access for an infrastructure corridor to connect Telfer and Havieron (haul road, powerlines, water pipes). This is not considered a risk to the timelines or project.

Potential Exploration Growth

The Havieron mineral system as outlined by drill testing to date, is an 650m x 350m ovate shaped NW trending alteration zone in which mineralisation is hosted by variable brecciation, and sulphide accumulations centred on a complex of nested diorite intrusions. Higher grade zones are associated with increases in sulphide accumulations including pyrrhotite, chalcopyrite and pyrite with quartz. The SE Crescent Zone is a geological domain characterised by massive sulphide accumulations. Mineralisation has been observed to over 1,000m in vertical extent below the 420m of post mineralisation cover sequence.

The Study only considers the Indicated Mineral Resource which is a relatively small proportion of the existing resource inventory. The Havieron project has significant additional growth potential including:

• Conversion of existing Inferred Mineral Resources
• Mineralisation open at depth and along strike
  • Extension of the SE Crescent Zone below the current Mineral Resource, where increasing grade and thickness of mineralisation has been observed in recent drilling
• Expansion of multiple higher-grade targets within the main Havieron NW corridor, including the Northern Breccia and NW Pod
• Potential for additional NW trending corridors including the Eastern Breccia; and
• Potential to discover additional mineralisation centres (at Havieron North, Zipa and Meco)

In addition to the active testing of the above higher-grade targets, drilling continues in the northern and eastern breccia corridors to assess the bulk extraction potential.

At the SE Crescent, drilling has extended the high-grade mineralisation ~250m below the base of the current Mineral Resource with two recent drillholes (HAD133 and HAD133W1) returning intervals >900 gram metres (Au ppm x length). These new intercepts show an increase in both grade and thickness with increasing depth. Drilling continues to assess the depth extents of SE Crescent which now has a vertical extent of over 900m.

At the Northern Breccia, drilling has extended the mineralised breccia footprint around the Mineral Resource extents. Drilling has confirmed and increased the continuity of internal higher grade Crescent-like mineralisation in a north-west mineralised corridor which now extends up to 300m in length, and 100m wide, between 4300 - 4100mRL, and remains open at depth. Results of greater than 150 gram metres (Au ppm x length) outside of the current Mineral Resource include¹⁴:
