Newcrest Announces Cadia PC1-2 Feasibility Study Demonstrates Strong Financial Returns
Cadia PC1-2 Feasibility Study demonstrates strong financial returns
Feasibility Study estimated IRR of 18% and NPV of US$1.4 billion over a 16 year mine life1,2,3,4
Confirms Cadia's position as a world class, long-life gold and copper producer
Optimised mine footprint with additional ore mined across the life of the project
Increased annual gold and copper production compared to the Pre-Feasibility Study
Early works continue to progress well, with first gold and copper production anticipated in FY265
Melbourne, Australia--(Newsfile Corp. - November 10, 2022) - Newcrest Mining Limited (ASX: NCM) (TSX: NCM) (PNGX: NCM) is pleased to announce that the Newcrest Board has approved progression of the Cadia PC1-2 Feasibility Study (the Study) to the Execution Stage.
The Study represents the next panel cave for execution at Cadia after PC2-3 and forms a key strategic milestone for Newcrest to maintain Cadia's long-life production profile, with the development of PC1-2 accounting for approximately 20% of Cadia's published Ore Reserves. The Study contemplates a high lift, undercut block cave producing up to 25 million tonnes1,2 of crushed ore per annum at a very attractive rate of return. First production from PC1-2 is expected in FY26, with execution targeted for FY295.
The Early Works Program remains on track with key development activities and raise boring currently underway. Preliminary earthworks to support construction of the primary ventilation system are also in progress.
Newcrest Managing Director and Chief Executive Officer, Sandeep Biswas, said, "We are very pleased to announce the findings of the Cadia PC1-2 Feasibility Study today, which indicates strong financial returns and underscores the quality of this world class asset. Together with the Cadia Expansion Project which is nearing completion, we are confident that Cadia will continue to be an outstanding gold and copper producer for decades to come."
"Through applying our technical expertise in deep underground mining and value breakthrough strategies, our team has further optimised the PC1-2 mine footprint since the Pre-Feasibility Study, creating a more efficient cave and substantially increasing expected ore production across the life of the project. We now expect to deliver additional gold and copper production over the next decade and beyond, which is an outstanding achievement by our team and a great example of our innovation and creativity in action."
"We also have significant financial headroom to fund the construction of PC1-2 through our internal cash flow and prudent use of our strong balance sheet. This further underpins Cadia's ability to continue contributing to the community and we remain focused on pursuing further optimisations during the Execution Stage of the project," said Mr Biswas.

Development of PC1-2 is expected to sustain total Cadia mine production at approximately 35 million tonnes per annum as production from the current operational PC1 and PC2 caves begin to decline from FY246. The first draw bell for PC2-3 was successfully fired in September 2022, with first production expected during the March 2023 quarter. The PC1-2 cave is expected to take approximately 6-7 years to reach its maximum production capacity following blasting of the first draw bell.

Metal price and exchange rate sensitivity analysis1,2,3,4
The actual IRR of the Study will vary according to the gold and copper prices realised. Base case assumptions include a gold price of US$1,500 per ounce, copper price of US$3.50 per pound, and an AUD:USD exchange rate of 0.75.
The table below outlines how the estimated Study IRR of 18% varies using different price assumptions:
|Gold price (per ounce)||1,250||15|
|Gold price (per ounce)||1,950||23|
|Copper price (per lb)||3.00||16|
|Copper price (per lb)||4.10||20|
Estimated project capital expenditure profile1,3,4
Total capital expenditure for the main works phase development of PC1-2 is estimated to be approximately
A$1.4 billion (~US$1.1 billion) on a real basis, and approximately A$1.6 billion (~US$1.2 billion) on a nominal basis over the following years:
|Project capital expenditure (main works)||FY23||FY24||FY25||FY26||FY27+||Total|
|Project Capital Expenditure (A$m)||139||297||329||260||411||1,437|
|Project Capital Expenditure (US$m)||105||223||247||195||309||1,077|
|Project Capital Expenditure (A$m)||144||315||358||290||474||1,581|
|Project Capital Expenditure (US$m)||108||236||268||217||355||1,185|
Cost assumptions and further optimisation opportunities
Changes in cost assumptions compared to the PFS are outlined below:
Project main works capital expenditure of A$1,437 million (real) is higher than the PFS project main works capital of A$1,122 million. The 28% cost increase is driven by a 10% increase in the extraction footprint, inflationary pressures, primarily across labour, contractors, steel, electricity and explosives, and an additional contingency allowance to account for increased volatility.
Sustaining capital expenditure of A$1,195 million (real) is ~2% higher due to inflationary pressures and additional costs associated with tailings storage, partly offset by value engineering.
Average All-In Sustaining Cost (AISC) across the life of the project of A$198/oz (US$148/oz) on a real basis is higher than the PFS AISC of A$54/oz (US$41/oz), mainly driven by higher operating costs, with inflationary pressures across labour, steel, electricity and processing consumables. In addition, copper recovery assumptions are lower, treatment and refining charges are increasing with market conditions deteriorating for shipping, freight, refining and smelting charges, and general and administrative costs are higher due to increasing insurance charges. These costs were partly offset by a higher copper price assumption.
Activities continue to be pursued to optimise the Study outcomes and reduce costs to maximise long-term value.
Newcrest continued to progress the early works program since the PFS release in August 2021, with A$74 million of capital expenditure incurred on key development activities, raise boring and earthworks to support construction of the primary ventilation system.
Cadia presently holds a major Project Approval for the Cadia East Project until calendar year 2031 (inclusive of the permit to develop PC1-2).
In December 2021, Cadia received approval from the New South Wales Department of Planning, Industry & Environment for a modification to increase its permitted processing capacity from 32Mtpa to 35Mtpa6. The modification also provided approval for Newcrest to repair the slumped section of the Northern Tailings Storage Facility and revise the footprint of the NTSF and Southern Tailings Storage Facility to allow for a change from upstream to a centreline lift design.
Cadia has commenced planning for the long-term continuation of mining operations known as the Cadia Continued Operations Project (CCOP). Key aspects of the CCOP include a proposed development for a new Tailings Storage Facility adjacent to the current Southern Tailings Storage Facility.
