Harmony Gold has generated 70 gigawatt-hours (GWh) of electricity by converting pressure from chilled water travelling through its deep-level gold mines into power, recovering energy that would otherwise go unused.
Harmony Gold produced 1.43Moz in the year to June 2026, within guidance, and lifted headline earnings per share 87% to 4,363c, with Mponeng and Moab Khotsong generating a 38% free cash flow margin.
Harmony Gold is expanding its Sungazer solar programme with a 100MW plant under construction at Moab Khotsong, part of a roughly R2bn plan to add wind, solar and PPA capacity across its South African mines.
Harmony Gold finalised its US$1.01bn acquisition of MAC Copper on 24 October 2025, taking full ownership of the CSA copper mine in New South Wales and adding copper to its production mix for the first time at scale.
