Botswana Diamonds has commenced an exploration program in its diamond reconnaissance license to the south of the Mobilong diamond field in Cameroon.

The purpose of the 60-90 day work program is to identify the presence and extent of the diamond bearing host rock that defines the Mobilong diamond field.

According to the company, it appears that the diamonds are hosted in a palaeo-conglomerate, from which they have since been eroded in places, and now also occur sporadically in modern alluvial deposits.

The program will include geological mapping, using traverses and cut-lines on a regular grid, accompanied by excavation of observation pits and the collecting of geochemical and rock samples for further analyses.

If successful, a limited drilling and trenching/pitting exercise will be implemented to further define the scope and extent of potentially diamondiferous rock sequences, the company said.
