Kalgold open pit

Our operations

Kalgold open pit

Kalgold is an open-pit mine situated 55 kilometres southwest of Mahikeng in North West Province and located within the Kraaipan Greenstone Belt. Mining takes place from the A Zone pit. Ore mined from the pit is processed at a carbon-in-leach plant located at Kalgold.

Performance FY16

Both the A and B mills were replaced in FY16. The elution upgrade project and plant refurbishment upgrades are underway and will improve plant efficiencies. Upgrades to the crushers and improved maintenance will aid improved performance of the operation in future.

Upgrades to the plant and underperformance of the crushing units impacted gold production in FY16.

Risks managed at Kalgold include the prevention of plant intrusions and gold theft and the performance of blasting and hauling operations in the pit.

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