This updated prefeasibility study covers the first stage of Golpu’s development. Stage 1 of the Golpu development targets the upper higher value portion of the orebody. Work will continue on optimising a second stage mine development (Stage 2), which will encompass the rest of the ore reserves. Both the feasibility study for the first stage and the updated prefeasibility study for the second stage of the project are scheduled to be completed by the end of calendar year 2015. The updated prefeasibility study entails low development capital cost, targets high grades to maximise free cash flow generation and demonstrates the potential of this world class ore body. “The updated prefeasibility study supports our view that Golpu is a spectacular ore body with a large copper component, affordable and mineable. Key objectives of the study have been achieved by reducing the capital of the project, lowering operating costs and improving the rate of return”, said Graham Briggs, chief executive officer (CEO) of Harmony. Harmony’s CEO notes that the development of the Golpu Project aligns with Harmony’s strategy of profitable, low-cost operations: “The conclusion of the updated PFS is a major project milestone and has demonstrated the significant potential of this world-class orebody, which contains mineral resources of 20 million ounces of gold and 9.4 million tonnes of copper. Attributable annual production for Harmony is significant and averages at 500 000¹ gold equivalent ounces per year in years 2024 to 2029. Stage 1 is expected to have a life of approximately 27 years”. The Golpu project team, with the assistance of WorleyParsons as project consultant, have incorporated a total of 52 000 new drill core samples into the updated study – significantly improving the understanding of the geological framework. This has redefined the boundaries of the high grade porphyry event in the upper part of the orebody, which will be mined by block caving method. This enables a reduction in the size of the footprint of the block caves compared to the 2012 prefeasibility study significantly reducing capital requirements. The Stage 1 project capital on a 100% basis is estimated at US$2.3bn, yielding an attractive return on investment with an internal rate of return of 17%. The updated prefeasibility study recommends the development of twin exploration declines to establish further geotechnical and geological data to support the feasibility study. A decision on the declines is anticipated in the first half of 2015. The two proposed block caves in Stage 1 are designed to access approximately 40% of the contained metal (gold and copper) of the Golpu reserve. The approximately 60% remaining of the reserve would be extracted by a future deeper block cave (Stage 2). The mining and processing infrastructure of Stage 1 would then be utilised to support development of Stage 2. Engagement with key stakeholders, including the PNG national government, the Morobe provincial government, landowners and community representatives continues to ensure clear alignment on the project objectives. Golpu has the potential to deliver significant benefits to local and regional communities and the broader economy of Papua New Guinea, including local business opportunities, taxation and royalty revenues to all levels of government. It will also offer benefits through training and employment opportunities, business and community development programmes, health and education investments and improved regional infrastructure. Environmental baseline studies and risk and impact assessments were undertaken as part of the updated pre-feasibility study and will be further developed during the feasibility study in preparation for the submission of an Environmental and Social Impact Assessment to the PNG Government for consideration. Harmony and Newcrest each own 50% of the Golpu Project through the Wafi-Golpu Joint Venture (WGJV). The PNG government retains the right to acquire up to a 30% interest in the project, at any time up to the date of granting the mining lease, at a price equal to the sunk costs at the date of acquisition. If this right is exercised, the government becomes a full equity partner in the project. “The Golpu project is a significant value accretive game-changer for Harmony”, says Graham Briggs, CEO of Harmony. “Harmony intends to fund the earlier stages of the project from internal cash flows, and reviewing other funding options for the latter stages. In the current environment of volatile gold prices, we are focussed – more than ever – on cost control and cash generation at existing operations. In addition, shareholder value is created through investing in Golpu, securing a sustainable, profitable future for Harmony.” Key items for Stage 1 (100%) AreaMeasureUnit ProductionFirst oreSteady-state productionOre minedLife of Stage 1Cu metal producedAu metal producedPeak gold production (Year 2025)Peak copper production (Year 2025)Gold recoveriesCopper recoveriesDateDateMtYearsMt CuMoz Aukoz pakt pa%%20202024146272.23.73201507794CapitalProject capitalSustaining capitalTotal life of Stage 1 capitalMaximum negative cash flowUS$bnUS$bnUS$bnUS$bn2.30.83.11.6OperatingTotal operating cost (real)Cash cost (C1) (after gold credits)Total production cost* (after gold credits)Cash costs (after copper credits)Total production cost* (after copper credits)US$/tUS$/lb CuUS$/lb CuUS$/oz AuUS$/oz Au34.60.781.42~ negative 1 700~ negative 950Economic assumptionsGold priceCopper priceExchange ratesUS$/ozUS$/lbAU$/US$PGK/US$1 2503.100.902.58Stage 1 outcomesPercentage of reserve utilisedInternal Rate of ReturnNet present value (at a discount rate of 8.58%)%%US$bn~40171.1 *Includes capital Overview of mining operationsGolpu is expected to comprise of at least two stages. The updated prefeasibility study for Stage 1 of Golpu recommends two block caves accessing the high value core of the Golpu ore body. Stage 1 extracts 146Mt at an average grade of 1.02g/t gold and 1.60% copper. The proposed start-up production rate is 3Mtpa mined from Block Cave 1 (BC1) and 6Mtpa mined from the deeper Block Cave 2 (BC2). BC1 is situated approximately 425m below surface and will extract 12Mt of cave ore over a five year period at a peak production rate of 3Mtpa. During caving operations, ore from the block cave draw points will be delivered by diesel load haul dump units to an underground jaw crusher and then conveyed to surface. BC2 is situated approximately 1 050m below surface. BC2 will be mined at a rate of 6Mtpa to extract 134Mt of cave ore over a 23 year period. Access to the orebody is planned to be via twin declines developed from the Watut River flats. During the production phase it is envisaged that an inclined conveyor is installed in one of the declines for transportation of production ore to the process plant located near the portal; the other being used for ventilation. The two proposed block caves in Stage 1 are designed to access approximately 30% of the tonnes, which contain approximately 40% of the metal (gold and copper) of the Golpu reserve. The mining and processing infrastructure would then be utilised to exploit the remaining 70% of the tonnes, which contain about 60% of the contained metal (gold and copper) of the Golpu reserve. Stage 2 will focus on block cave 3 (BC3). Study work completed to date on Stage 1 and Stage 2 combined indicates no material difference in metal recovered from the 2012 reserve. Capital costs and funding The capital cost estimate has been completed to a Prefeasibility level of accuracy and includes all capital from 1 January 2015.

From FY21 Stage 1 will be cash flow positive after capital expenditure. Operating costs The key driver for the mining costs is the power requirements for ventilation, cooling and mine dewatering, which accounts for $6.56/t (55%) of the mining costs. The key driver for ore treatment costs is also power, which accounts for 42% of treatment costs. Power is a key project driver that influences both mining and treatment cost assumptions. The study has used a power price assumption of US20c/kWh. The Project will source bulk power from either its own power station or from an independent power producer.

The cash flow for Stage 1 forecasts a maximum negative cash position of US$1.6bn in 2020 as the project moves into initial production from BC1. Once BC2 is in full production in 2024, it is estimated the project will produce significant free cash flows, with total undiscounted free cash flow of approximately US$5.8bn over the 27 year life of Stage 1. Stage 1 positions Golpu as a lowest quartile cost producer with copper including capital (C3) at US$1.42/lb and the cash cost for gold at approximately negative US$1 700/oz. Process plant, infrastructure and waste management The updated study anticipates the construction of a 6Mtpa process plant scheduled for commissioning in the first year of production in calendar year 2020, which will produce a copper-gold concentrate. The Golpu project is located in a greenfields location. The main infrastructure requirements for the Golpu project are access roads, tailings storage, water management, port facilities and power supply and transmission. It is expected that the copper-gold concentrate will be filtered at the mine site and transported to the Port of Lae by trucks for the initial production, with the concentrate to be pumped to the filtration plant located at the port as production rates increase. Summary of next steps The updated prefeasibility study recommends the development of twin exploration declines to establish further geotechnical and geological data. A decision on the declines is anticipated in the first half of 2015. The feasibility study will address and finalise technical issues identified in the prefeasibility study. It will progress further environmental, social and cultural heritage studies associated with access roads and tailings storage. Further work will also be conducted to identify the optimal solution for power for the operations. Advanced exploration activities are subject to board and government regulatory approval. The Harmony board will consider the advanced exploration activity in the first half of calendar year 2015, once a pre-development agreement has been concluded. Both the Stage 1 feasibility study and the updated prefeasibility study for Stage 2 are targeted to be completed by the end of calendar year 2015. 1 Equivalent gold ounces converted by using a copper price of US$3.10/lb and a gold price of US$1250/oz Please also refer to the presentation in support of this release.
