Joel Mine

Our operations

Joel

Joel is located in the Free State Province and about 292 kilometres from Johannesburg, on the southern edge of the Witwatersrand Basin. The mine comprises two shafts, the North and South shafts. The primary economical reef horizon at Joel is a narrow tabular Beatrix Reef deposit which is accessed via conventional grid development. Mining is conducted at a depth of 1 452 metres. The ore is processed at the Joel plant.

Performance FY16

Managing shaft and project schedules is critical for Joel. Capital development on the decline project progressed well in FY16 and is expected to be completed in FY17. First production from this area is expected in July 2017. Joel's future operating life depends on the successful completion of the decline project, which began in FY15.

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