Drill Results Map — South Africa

To create a drill results map for South Africa, import your ZA claims or data as GeoJSON, assign the appropriate layer role for automatic styling, set the Light or Satellite basemap, and export as PNG or PDF. The entire process takes 15–30 minutes with no GIS experience required.

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).

What is a Drill Results Map?

A drill results map plots the collar locations of completed drill holes alongside key assay results — typically highest-grade intercept, hole depth, and azimuth. It is the standard figure included in exploration news releases and is scrutinized by investors and analysts to understand the spatial distribution of mineralization.

How to Create a Drill Results Map for South Africa

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

Who regulates mineral claims in South Africa?
Mineral claims in South Africa are regulated by the Department of Mineral and Petroleum Resources (DMPR). All tenure and claims data can be queried through South African Mineral Resources Administration System (SAMRAD).
What minerals are typically mapped in South Africa?
South Africa is known for its gold, platinum group elements, chrome, manganese deposits. Key producing and exploration-stage properties include Witwatersrand Gold Basin, Bushveld Complex, Venetia Diamond Mine. The main mining districts are Witwatersrand, Bushveld Complex, Northern Cape.
Can I export a South Africa drill results map for a SAMREC Code report?
Yes. Exploration Maps exports PNG and PDF at 2–3× pixel ratio, suitable for inclusion in SAMREC Code technical reports as required figures. The export includes north arrow, scale bar, legend, and title block — all standard map elements required for SAMREC Code compliance.
