Free State surface operations

Our operations

Surface dumps

There are reserves available in rock dumps around our Free State operations. A programme run by metallurgical services is under way to mill and process these dumps when there is spare capacity.

Performance FY16

In FY16, Central Plant only processed re-mined, redundant plant clean-up and rock dumps.

The processing of the rock dumps is approaching its end as virtually all of the higher-grade dump material originally available has been processed, leaving only lower-grade material. During FY16, the Central Plant tailings retreatment project started, aimed at upgrading the plant to process only tailings. The life of the tailing retreatment project is expected to be 19 years and upgrades are scheduled to be completed by the end of FY17.

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