Tsodilo says completion of BK16 drilling programme in the offing

19 may 2017
Tsodilo Resources said a pilot hole drill programme at its BK16 kimberlite project in Botswana will be completed end of this month-end.
Fourteen holes totaling approximately 3,100 meters had been planned with 11 completed to date.
This was expected to provide just under 2 000 t of kimberlite for processing.
The pilot hole pattern was designed to achieve an approximate 50-metre grid hole spacing for the first phase large diameter drilling (LDD) sampling.
Tsodilo said the primary objectives of the pilot holes were to improve on and upgrade the knowledge of the internal geology of the kimberlite and optimise the kimberlite intersected by the LDD programme.
“Geotechnical studies of the cores will allow for the selection of the appropriate LDD drill bits based on rock hardness and the pilot hole cores will also provide a reference once the diamond recovery results have been obtained from the LDD programme,” it said.
The BK16 kimberlite project is located within the Orapa Kimberlite Field (OKF).
Of the 83 known kimberlite bodies in the OKF, nine had been or are currently being mined. These included Debswana’s Orapa and Lucara’s Karowe.
