Overview
Production from processing surface-rock dumps, situated across Harmony’s Free State operations, depends entirely on the availability of spare mill capacity at the various operational plants. Waste and waste-rock dump deliveries to the Kusasalethu plant (near the border of Gauteng and North West provinces) supplement mining volumes to secure sufficient backfill to use as support in stoping areas.
Waste-rock dumps near Orkney are treated at the Great Noligwa and Mispah plants. Milling of waste-rock dumps at the Doornkop plant, in Gauteng, began in FY18. Waste-rock dumps and tailings facilities acquired with Mponeng are treated at the Mponeng, Kusasalethu and Savuka plants.

Operating performance FY24
Production for the waste rock dumps increased in FY24 to 4.16 million tonnes being processed, 6% more than the 3.94 million tonnes in FY23. The recovered grade also improved year on year to 0.414g/t from 0.392g/t in FY23, a 6% improvement. As a result gold production increased by 12% to 1 724kg (55 429oz) from 1 541kg (49 544oz) in the previous year. A higher gold price received supported by the increase in production resulted in a rise in gold revenue to R2 100 million (FY23: R1 631 million). The average gold price received for FY24 increased by 16% to R1 222 494/kg from R1 052 903/kg in FY23.
All-in sustaining cost decreased 6% to R810 746/kg (FY23: R859 974/kg) due to the increase in gold production. Cash operating costs increased 6% mainly due to inflationary as well as annual electricity tariff increases. A total of R4 million was spent on capital in FY24 (FY23: 12 million).
Our focus area in FY25
Our priority is to continue safe, profitable production by maintaining costs and improving mining efficiencies.
