Group Ore Reserves
As at 31 December 2021, Group Ore Reserves are estimated to contain approximately 54 million ounces of gold, 7.9 million tonnes of copper, 30 million ounces of silver and 0.11 million tonnes of molybdenum. This represents increases of approximately 5 million ounces of gold (~10%) and 1.1 million tonnes of copper (~2%) and decreases of approximately 5 million ounces of silver (~17%) and 0.01 million tonnes of molybdenum (~8%) compared with the estimate as at 31 December 2020. The Group Ore Reserve estimates as at 31 December 2021 are set out in Tables 15 to 19. Tonnes are reported as dry metric tonnes. All Group Ore Reserves are classified as Probable Reserves except for 58 million tonnes of Lihir Stockpiles that are Proved Reserves. All tabulated tonnes, grade and metal information has been rounded to two significant figures to reflect appropriate precision in the estimate, and this may cause some apparent discrepancies in totals.
The Group Ore Reserves as at 31 December 2021 includes the following changes as compared to 31 December 2020:
- Estimated mining depletion of approximately 2.4 million ounces of gold, 0.1 million tonnes of copper, 0.8 million ounces of silver and minor molybdenum.
- Cadia East Underground decrease of 1.6 million ounces of gold, 0.2 million tonnes of copper, 4.6 million ounces of silver and 0.01 million tonnes of molybdenum due to mining depletion (0.9 million ounces of gold, 0.1 million tonnes of copper and 0.8 million ounces of silver) and an updated Ore Reserve estimate informed by additional drilling, revised input assumptions and exclusion of some dilution material.
- Red Chris Ore Reserves initial estimates added 5.6 million ounces of gold and 1.5 million tonnes of copper.
- Havieron Ore Reserve initial estimate added 0.65 million ounces of gold and 0.03 million tonnes of copper.
- Lihir added one million ounces of gold in Probable Reserves, underpinned by completion of the Phase 14A Pre-Feasibility Study.
- O'Callaghans Ore Reserve has been withdrawn pending outcomes from planned strategic, technical and financial studies.

Mineral Resources and Ore Reserves Assumptions
Mining, metallurgical and long-term cost assumptions were developed with reference to performance data. The revised assumptions include changes in performance consistent with changing activity levels at each site over the life of the operation and the latest study for each deposit.
Long-term metal prices and foreign exchange assumptions for Mineral Resources and Ore Reserves are presented in Table 2. For long and short mine life assets, all metal prices, AUD:USD exchange rate and USD:PNG kina exchange rate applied are unchanged for both Mineral Resources and Ore Reserves compared to December 2020 prices used for reporting.
In consideration of Telfer's current comparatively short mine life, the gold price assumption is US$100/oz higher and the copper price assumption is US$0.20/Ib lower than prices applied for Ore Reserves reporting of long life assets. The AUD:USD exchange rate is also reduced to 0.70.
Note that long term metal prices and exchange rate assumptions are applied to Havieron Mineral Resources and Ore Reserves. Where appropriate, Mineral Resources are also spatially constrained within notional mining volumes based on metal prices of US$1,400/oz for gold and US$4.00/lb for copper. This approach is adopted to eliminate mineralisation that does not have reasonable prospects of eventual economic extraction from Mineral Resource estimates.
Undeveloped projects at Wafi-Golpu and Telfer will be progressively re-optimised when the full supporting studies are updated and are currently optimised on the more conservative (US$100/oz lower) 2019 gold price assumption.
Mineral Resource and Ore Reserve cut-off criteria are described in Table 3.
Ore Reserve metallurgical recovery assumptions are described in Table 4.
A discussion of the known legal, political, environmental, or other risks that could materially affect the potential development of the Ore Reserves and Mineral Resources for each of the material properties Cadia, Lihir, Wafi-Golpu and Red Chris can be found in the Technical Report for each project (referred to below).

JORC Code and ASX Listing Rules Requirements
This annual statement of Mineral Resources and Ore Reserves has been prepared in accordance with the JORC Code. Mineral Resources and Ore Reserves reported for the Wafi-Golpu Joint Venture (WGJV) are quoted as Newcrest's 50% interest. Mineral Resources and Ore Reserves reported for the Havieron Joint Venture are quoted as Newcrest's 40% interest. Mineral Resources and Ore Reserves reported for the Red Chris Joint Venture are quoted as Newcrest's 70% interest and Mineral Resources reported for the Namosi Joint Venture are quoted as Newcrest's 72.74% interest.
JORC and CIM Comparison
Mineral Resources and Ore Reserves are classified using the JORC Code. The confidence categories assigned under the JORC Code were reconciled to the confidence categories in the CIM Definition Standards. As the confidence category definitions are the same, no modifications to the confidence categories were required.
There are differences in terminology from JORC compared to the CIM Definition Standards. Terminology differences are the term "Ore Reserves" in the JORC Code is equivalent to "Mineral Reserves" using the CIM Definition Standards, and the term "Proved Ore Reserves" in the JORC Code is equivalent to "Proven Mineral Reserves" using the CIM Definition Standards. There are no other material differences between JORC and the CIM Definition Standards.
Note that NI 43-101 reporting requirements do not permit Inferred Mineral Resources to be added to other Mineral Resource categories. Therefore, Measured and Indicated Mineral Resources have been reported separately from Inferred Mineral Resources.
Mineral Resources that are not Ore Reserves do not have demonstrated economic viability. Due to lower certainty, the inclusion of Mineral Resources should not be regarded as a representation by Newcrest that such amounts can necessarily be totally economically exploited, and investors are cautioned not to place undue reliance upon such figures. Therefore, no assurances can be given that the estimates of Mineral Resources presented in this statement will be recovered at the tonnages and grades presented, or at all.
