Botswana Diamonds discovers kimberlites of up to 1.15 ha in size at SA project

21 november 2017
Botswana Diamonds said results from the survey work conducted at its Free State project, in South Africa, has indicated that sizes of kimberlites found ranged from 0.3 hectares to 1.15 hectares.
The objective of the survey work was to discover the surface area of the kimberlites, following the re-discovery of eight Group 1 kimberlites last month.
The sizes, it said, were determined using a combination of magnetic, electromagnetic and gravity geophysical techniques, which had resulted in “very strong” images of the footprints of the kimberlites.
"The re-discovery of 8 kimberlites in a highly prospective diamond area was very positive. We now know the sizes of each pipe/dyke and we believe that each could contain diamonds,” said company chairperson John Teeling.
He said the next step was to evaluate the diamond indicator minerals in each pipe to decide priorities for drilling.
