HARMONY GOLD : MOAB KHOTSONG MINE
Long Business Description

Moab Khotsong is a deep-level mine near the towns of Orkney and Klerksdorp, some 180km south-west of Johannesburg. The mine, which began producing in 2003, was acquired from AngloGold Ashanti Limited in March 2018.
Mining is based on a scattered mining method, together with an integrated backfill support system that incorporates bracket pillars. The geology at Moab Khotsong is structurally complex, with large fault-loss areas between the three mining areas (top mine (Great Noligwa), middle mine and lower mine (growth project and Zaaiplaats project in execution phase)). The mine exploits the Vaal Reef as its primary orebody. The economic reef horizons are mined between 1 791m and 3 052m below surface. Ore mined is processed at the Great Noligwa gold plant. The plant uses the reverse gold leach method, with gold and uranium recoveries achieved by gold cyanide and uranium leaching.

OPERATING PERFORMANCE FY21
The mine is the group’s second-largest gold operation. It contributes 15% of total production and is the largest contributor to operating free cash flow. Along with higher revenues and costs in the post-lockdown period capex rose by 27%, associated mainly with ongoing development and infrastructure to extract and mine the pillar in Great Noligwa.
EXPANSION PROJECT
The Great Noligwa pillar extraction feasibility study was completed in FY2021. With implementation the second rock transfer system was completed and commissioned. Harmony’s extensive pillar-mining expertise is being used to develop the infrastructure for extracting and mining the pillar.
