Accretion
Accretion, the opposite of erosion, is a gradual process in which layers of a material are formed as small amounts are added over time.

Exploration
Once an area has been opened for mining through accretion, exploration work commences to determine the availability of resources in the area.

Strip mining
A form of surface mining which involves the removal of a layer of material known as overburden to access buried mineral deposits.

Bedrock cleaning and Bulk Excavation
The main function of bulk excavation and bedrock cleaning is to extract all diamondiferous gravel from the bedrock footwall.

Loading & Hauling
The collected/bulked diamondiferous material is loaded onto ridged frame trucks (RFT’s) with a Front-End loader through the process of Loading & Hauling.

Treatment
The concentration process of the ore consists of crushing, screening, scrubbing and dense-medium separation.

Dimond Sorting
Concentrated diamond rich materials are introduced into the Red Area Complex (RAC) by means of concentrate transfer silos or dumper trucks from the various sources.

Final product
After treatment, the concentrated diamond rich material is transported to the Red Area Complex for final recovery through x-ray luminescence technology and sorting of diamonds. As part of sorting, mat
