Kalgold open pit

Our operations

Kalgold open pit

Kalgold is an open-pit mine near Mahikeng, accessing gold-bearing ore in a banded ironstone formation in Kraaipan Greenstone Belt. Tonnage mined at Kalgold is treated at carbon-in-leach plant site.

Performance FY14

Kalgold experienced a series of challenges throughout the year with concomitant falls in gold production. In the first quarter, crusher system operations were affected. However, in the interests of maintaining cash-flow positive operations, capital spending on new mills was deferred. This proved to be the correct strategy during the third quarter when mill grades fell following heavy rains which resulted in delayed blasting of higher-grade ore blocks. Plans to improve production include a focus on maintenance of the crusher so as to enhance mill throughput and an upgrade of the elution plant.

The Kalgold plant upgrade is starting to yield improved throughput results. The plant struggled with poor gold recovery during the last two months of the year. The A zone pit is changing from oxide ore to sulphide ore.

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