About Mining in South Africa

South Africa holds the world's largest known gold reserves and produces more than 70% of global platinum group elements. The Witwatersrand Basin is the world's largest gold deposit by historical production, and the Bushveld Complex is the world's largest layered igneous intrusion, hosting the majority of the world's platinum, palladium, and chrome resources.

Key minerals: gold, platinum group elements, chrome, manganese, iron ore, diamonds. Notable deposits: Witwatersrand Gold Basin, Bushveld Complex, Venetia Diamond Mine, Sishen Iron Mine. Mining districts: Witwatersrand, Bushveld Complex, Northern Cape, Limpopo.

The Department of Mineral and Petroleum Resources (DMPR) administers mineral rights in South Africa. Claim data is accessible through South African Mineral Resources Administration System (SAMRAD).

How to Create a Drill Results Map for South Africa

For a full step-by-step guide to drill results maps, see How to Make a Drill Results Map.

Import your drill collar CSV (columns: hole ID, latitude, longitude, depth, assay)
Assign the Drillholes layer role
Import the property claims boundary as GeoJSON
Add callout labels to key holes showing hole ID and best intercept
Use Badge Label type to highlight the highest-grade holes
Configure the title with program name and date
Set the Landscape 16:9 ratio for news release figures
Export as PNG at 2× for email and PDF for the news release attachment
