FY19 Operational Update Harmony Gold Mining Company Limited Registration number 1950/038232/06 Incorporated in the Republic of South Africa ISIN: ZAE000015228 JSE share code: HAR (“Harmony” and/or “the Company”) FY19 OPERATIONAL UPDATE Johannesburg. Thursday, 25 July 2019. Harmony Gold Mining Company Limited (“Harmony” or the “Company”) is pleased to announce that annual gold production of 1.44 million ounces was in line with its financial year 2019 (“FY19”) guidance. “Harmony’s FY19 operating performance was boosted by the inclusion of a full financial year of production from both Moab Khotsong and Hidden Valley. We are committed to increasing margins, which is achieved by mining safely and delivering increased profitable production”, said Peter Steenkamp, chief executive officer of Harmony. Year on year, Harmony delivered a 17% increase in gold production of 1.44 million ounces, in line with its FY19 guidance of 1.45 million ounces. Underground recovered grade was 2% higher at 5.59g/t in FY19 (FY18: 5.48g/t), the seventh consecutive year of achieving an increase in underground recovered grade. All-in sustaining unit cost (“AISC”) is expected to be higher than the guided R540 000/kg, at between R550 000/kg and R555 000/kg – a year-on-year increase of about 8%. The increase in AISC is mainly due to inflationary increases and lower production at the Tshepong Operations (as previously reported). In US$ terms, AISC is expected to be about 2% lower at between US$1 210/oz and US$1 220/oz. Harmony recorded a gold price received of approximately R586 000/kg or US$1 286/oz (including the Rand gold hedge) in FY19. Detailed annual operating and financial results for the year ended 30 June 2019 will be announced on Tuesday 20 August 2019. Wafi-Golpu permitting update Recent developments in Papua New Guinea (“PNG”) have resulted in a delay to permitting of the Wafi-Golpu Project. These developments include the period culminating in the PNG Parliament’s election of a new Prime Minister, as well as the delay associated with legal proceedings between the National Government and the Morobe Provincial Government regarding the internal distribution of PNG’s economic interests in the project. The permitting delays compelled the Wafi-Golpu Joint Venture (“WGJV") to defer and revise the planned work program it had planned to commence this calendar year. General operation of the site, community programs, environmental monitoring and engineering activity all continue, although at a reduced scale in an attempt to mitigate the costs of the permitting delay. The PNG Government continues to signal its support for the project and the WGJV is well placed to resume discussions with the PNG Government given the constructive progress already made on the various agreements required for completion of the permitting process and the grant of a Special Mining Lease. It is difficult to estimate the duration of this delay and the market will be advised when discussions recommence. ends.
