COMPILATION AND CATEGORIZATION OF SOUTH AFRICA’S GOLD AND PGM RESOURCES

Challenge

South Africa’s mining industry lacks a compilation of the remaining PGM and gold resources, with an identification of green- and brownfields areas for future exploration and mining. It is also important for such a compilation to categorise the resources in terms of geological and geotechnical characteristics, with the long-term objective of reversing the decline of the mining industry.

Research and development

A three-phased approach was adopted: The research team collected data related to gold and PGM resources.

The data sources include listed and unlisted explorers; listed and unlisted miners; defunct mines; and online sources. These have been captured into a database. The research team is digitally capturing, or obtaining shareholder plans, reef wireframes and underground infrastructure; and they are establishing polygons of mined and unmined reefs. The team categorised resources using criteria such as depth; resource types; structural disturbances; and geotechnical settings.

Solution

The research team has developed a custom-designed database; and a visualisation map of captured data, with information pertaining to the aforementioned criteria. A total of 23 areas, from the South Rand and Natal, to Kraaipan and Pilgrim’s Rest is covered in the visualisation maps.

Status

This project is still in progress. A detailed Sector Coupling Model is to be developed from the study findings; it will guide the understanding of the coupling of electricity, heat/cooling and transport. Specialised tools (PLEXOS) will be utilised to model optimal investment opportunities.
