Sampling Method and Approach

Exploration work involves the collection and analysis of samples for the recovery of kimberlitic indicator minerals ("KIM(s)"). Various KIM sample types have been collected to date.

Kimberlite has been excavated from pits to assist in the delineation of internal Kimberlite phase variation and to assess diamond potential for optimisation of the proposed bulk sample program. Samples for hand specimen description, petrographic description, Mantle Mapper(tm) processing, whole rock geochemistry and microdiamond recovery have been collected.

The Mothae Project is an evaluation project and the recovery of micro-diamonds and macro-diamonds will be the essential elements of the program.

Samples of Kimberlite will be extracted by drilling or excavated from pits/trenches. The processing of these samples will be as follows:

  • Caustic fusion analysis for microdiamonds
  • Bulk sample treatment for macrodiamond grade
  • Bulk sample treatment for diamond value.
