Further to its SENS announcement on 24 March 2020 relating to the 21-day national lockdown announced by South Africa’s President on 23 March 2020 to address the spread of COVID- 19 in the country, Harmony Gold Mining Company Limited (“Harmony” and/or “the Company”) provides the following update. Committed to curb the spread of COVID-19 “The health and safety of all of our employees - and in particular those who continue to work on the care and maintenance of our mines, as well as at Hidden Valley – remain our highest priorities. We continue to ensure compliance with all prescribed and recommended preventive measures – in both South Africa and Papua New Guinea,” said Harmony’s CEO, Peter Steenkamp. Production in South Africa Underground mining operations in South Africa All nine of the Company’s underground mines in South Africa have ceased mining and are now on care and maintenance in terms of the requirements of the national lockdown. Care and maintenance includes the continued provision of various essential services such as water, power and security and the operation of health hubs at each mine. Surface treatment plants and surface retreatment operations All surface treatment plants at the underground mines continue to process pre-existing surface reef and waste, and surface retreatment operations continue to treat surface tailings, in line with the concessions announced by the Minister of Mineral Resources and Energy on 25 March 2020. Open-pit mining operation in South Africa Kalgold, the Company’s open-pit mining operation in South Africa’s North West Province, continues to mine and treat its ore at a reduced rate. Limited gold production during lockdown It is anticipated that Harmony will only produce between 650kg to 700kg of gold in South Africa during the 21-day lockdown period. Cash preservation is key, and as such all exploration and capital projects have been suspended. Production in Papua New Guinea (“PNG”) to continue Hidden Valley Hidden Valley will continue to mine in line with its plan, subject to any directives issued in line with PNG’s National Security Plan of Action in response to COVID-19.
