It takes years of searching, cutting-edge science and sophisticated technology, coupled with traditional mining know-how to find diamonds.  We explore in two stages, each supported by extensive field and laboratory resources.

Early stage exploration - In the reconnaissance and discovery phases, we decide where to explore and identify targets for further analysis by:

  • Conducting geophysical studies from the surface
  • Sampling soil and stream sediments for indicator minerals
  • Drilling to extract materials for examination

Advanced exploration - Not every discovery is an economically viable kimberlite – in fact, the vast majority are not. We use the following advanced techniques to determine which ones are.

  • Microdiamond analysis uses the size, frequency and distribution of tiny diamonds to assess potential and prioritise projects
  • Macrodiamond analysis extracts diamonds from bulk samples to determine grade and estimated value

Unparalleled diamond exploration experience, geological and mineral expertise and globally benchmarked laboratory services support our exploration activities.

Exploration activities

We continually seek out new diamond deposits, investigate the outer limits of our existing mines and analyse former mines to see if new technologies can economically recover additional diamonds.  Our current activities include:

  • Angola - Early and advanced stage exploration
  • Botswana - Geophysical surveys and drilling of selected targets near the Orapa Mine
  • Canada - Deposit assessment drilling of two satellite pipes in the Victor cluster
  • South Africa and India - Technical reviews of data to define high priority target areas
