Sikwane Project

  • There are 9 known kimberlites in the DES Sikwane Prospecting Licences. These were previously drilled, modelled and relinquished by De Beers due to their small size. The kimberlites of highest interest are Sikwane 01 and Sikwane 07.
  • Sikwane 01 is a kimberlite sill, subcropping over an area of approximately 20 ha with drilled intersections varying between 0.2m to 9m at depths of between 3.5m to 25m. An in situ tonnage of 300,000 to 600,000 tons is possible.
  • Sikwane 07 is modelled as a pipe of approximately 1ha size. This pipe was not drilled due to an ephemeral dam overlying the kimberlite. It remains a priority due to its larger size and drilling is proposed in the dry season
  • The Sikwane kimberlites are on a regional linear trend of 500million year old kimberlites that has proved elsewhere to be economically significant (e.g. Venetia and The Oaks in South Africa, Martins Drift in Botswana, and Beit Bridge and Murowa in Zimbabwe).
  • Macro diamonds (>1mm) were recovered in Sikwane 01 during historic De Beers percussion drilling indicating good diamond grade potential.
  • The chemistry of associated kimberlitic minerals from these kimberlites is indicative of good potential for diamond mineralisation.
  • 120kg of kimberlite from Sikwane 01 has been acquired from recent DES core drilling which can be submitted for micro-diamond analysis to rapidly establish preliminary diamond grade estimation.
  • The shallow depth of Sikwane 01 presents an opportunity for rapid mineral resource and small mine development though initial bulk sampling (which could be funded through diamond revenue).
