HARMONY GOLD MINING : OPERATIONAL UPDATE FOR THE NINE MONTHS ENDED 31 MARCH 2021

Johannesburg - Harmony Gold Mining Company Limited ('Harmony' or 'the Company') is pleased to report its operational performance for the nine months ended 31 March 2021.

Harmony has delivered another strong set of operational results year-on-year on the back of the successful integration of Mponeng and related assets into its portfolio, and a stronger Rand per kilogram gold price. The combination of a higher gold price received and improved EBITDA margin has resulted in strong cash generation and further strengthening of the Company's balance sheet. Growing the Company's ounces and margins in a safe and capital-responsible manner will guide each of its decisions as it continues to invest in both its people and its assets.

With a sturdy balance sheet and astute capital decisions, Harmony is well positioned for the next phase of its growth strategy. The Company has a pipeline of cash-enhancing projects which will boost its cash flow margins and sustain its production for many years to come. In addition, the tier 1 Wafi-Golpu project offers both commodity and geographic diversification, further transforming Harmony's portfolio as it focuses on becoming a lower risk and higher margin business.

Harmony has a proven track record in sustaining communities, creating jobs and unlocking significant value from assets well beyond their initial life of mine. Environmental, Social and Governance ('ESG') practices are embedded in how the Company operates and makes decisions to ensure sustainable mining. Through its successful track record, Harmony has become not only the South African gold mining champion, but also an established player in Papua New Guinea.

Harmony has an exciting story to tell and a wealth of emerging market experience. The combination of its existing asset portfolio, Wafi-Golpu and other brownfield projects will allow the Company to build on its copper-gold story while it continues to create value for all shareholders and stakeholders.
