Mineral resources and mineral reserves

 
 
   
 

Geology: The Kalgold operation is located within the Kraaipan Greenstone Belt, 60km south of Mahikeng. This is part of the larger Amalia-Kraaipan Greenstone terrain, consisting of north-trending linear belts of Archaean meta-volcanic and metasedimentary rocks, separated by granitoid units. Mineralisation occurs in shallow dipping quartz veins, which occur in clusters or swarms, within the steeply dipping magnetite-chert banded iron formation. Disseminated sulphide mineralisation, dominated mostly by pyrite, occurs around and between the shallow dipping quartz vein swarms. The D zone is the largest orebody encountered and has been depleted. Mineralisation has also been found in the Mielie Field zone (adjacent to the D zone), the A zone and A zone west (along strike to the north of the D zone), and the Watertank and Windmill areas to the north of the A zone. Current operations are focused on mining the Watertank and A zone open pits.
