Unisel Mine Headgear

Our operations

Unisel

Unisel is located in the Free State Province, near Virginia and about 271 kilometres from Johannesburg. Mining is conducted at a depth of 2 153 metres below surface. Conventional scattered mining and pillar reclamation takes place to access the Basal, Leader and, to a lesser extent, the Middle reefs. Ore mined is processed at Harmony One plant.

Performance FY16

Unisel is nearing the end of its operating life, but has been a good performer despite being Harmony's oldest operating mine. Unisel's aging operations and infrastructure present significant challenges to the mine's operational flexibility and to the maintenance of production.

More detailed information on safety performance can be found in the Integrated annual report.
