Botswana –Tsodilo Resources, an international diamond and metals exploration company, has completed the purchase of a dense medium separation (DMS) treatment plant for use at its BK16 kimberlite project located within the Orapa Kimberlite Field (OKF) in Botswana.
In 2014, the OKF area produced 13 355 292 carats
TSX-V-listed Tsodilo is currently completing the diamond core drilling programme of 15 holes to a cumulative depth of 2 621 m on both the main and satellite bodies of kimberlite BK16 in order to develop an advanced geological model.
In anticipation of the bulk sampling program, which is scheduled to start during the second half of this year, the company purchased the DMS mobile plant from diamond miner De Beers Botswana.
Botswana diamond mines have produced an average of 27 million carats annually in the last ten years and Botswana is the world’s largest producer of diamonds by value
The DMS plant is capable of handling a 10 t/h head feed throughput and was used in the evaluation of Lucara Diamond Corporation’s AK06 Karowe diamond mine.
The plant is located just outside the Lethlakane village about 15 km directly WNW from the BK16 kimberlite pipe.
The plant is equipped with primary and secondary crushers (cone and jaw), de-sliming screens, conveyors, a scrubber with 12 mm trommel screen, a DMS preparation screen and DMS cyclone (250mm/57mm).
It is also equipped with a laboratory, security office and concentrate storage units.
Tsodilo intends to spend some time refurbishing the plant in order to start treatment of the diamondiferous BK16 kimberlite during Phase 1 of the evaluation programme, which is to take place towards the end of 2015.
Using very conservative estimated grades the company intends to extract and treat some 3 500 t in order to recover in excess over 200 carats during Phase 1 of the evaluation program.
Tsodilo chairperson and CEO James Bruchs says: “Tsodilo continues to advance its projects in an expedient and cost effective fashion by using its company-owned drill rigs, geophysical equipment and now the DMS processing plant. This allows us to evaluate the potential of our projects in a fast and cost effective fashion which is crucial at any time but especially in today’s economic environment. The outlook for diamonds is very positive and we want to move BK16 along as fast as we can.”
