Masimong housing project

Our operations

Masimong

Masimong is located in the Free State Province, near the city of Welkom and about 260 kilometres from Johannesburg. The Masimong complex comprises an operating shaft (5 shaft), and a second shaft (4 shaft), which, although closed for mining, is used for ventilation, pumping and as a second outlet. Masimong exploits the Basal Reef and the B Reef. Mining is conducted at a depth of 2 050 metres. Ore mined is processed at the Harmony One plant.

Performance FY16

Masimong was restructured in FY15 to improve its profitability by scaling down ore body development in an effort to reduce costs and increase margins. As a result, the expected life of mine was shortened to three years.

During FY16, Masimong's production was negatively impacted by safety stoppages. Grade management and quality mining practices are important to achieve increased recovered grades.

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