It was planned to set up fourteen wells with a total length of about 3100 meters, with eleven of them are completed by now.
It was expected that recycling will receive about 2,000 tonnes of kimberlite.
Pilot holes were designed so as to ensure an approximate 50 meter spacing for the first stage of drilling large diameter (LDD).
The Tsodilo said that the priorities of the experimental wells are to obtain new data on the internal geology of the kimberlite and kimberlite optimization intersected program LDD.
"Geotechnical investigation cores enable to select suitable drill bits LDD based on rock hardness as well, core holes to test wells will also be reference as soon as the results obtained in diamond production under the LDD program", - said in a statement.
BK16 kimberlite project is located within kimberlite field Orapa (Orapa).
Of the 83 known kimberlite bodies Orapa being developed 9. These include the project of Debswana Orapa mine and cars (Karowe), owned by Lucara.

(thediamondloupe.com) - In April 2017 in Geneva symposium was held under the name "synthetic diamonds: the watch industry and jewelry under the threat of" specially to discuss the issue of synthetic stones in the field of horology, and how you can distinguish natural from diamonds grown in laboratories.
Events of the past decade have led to a critical moment, when the price of synthetic diamonds has dropped below the price of natural diamonds, increasing the incentive for blending synthetic mimics natural diamonds. The risk increases significantly when it comes to diamonds, "chalk" and watch industry - and, ultimately, consumers - are concerned.
CEO of Diamond Manufacturers Association (Diamond Producers Association, DPA) Jean-Marc Lieberherr (Jean-Marc Lieberherr) says: "The worst thing that can happen - this is what people will lose confidence in diamonds, because they are not sure that the product that they are buying is authentic. This is the number one challenge for us. "
Dr. Philip Martino (Philip Martineau), head of the research department at De Beers Research Center, said: "Consumers should be able to buy what they want, without fear of distortion of the facts we see that the price of synthetic diamonds are falling very quickly, and the difference. in prices between natural and synthetic stones is growing rapidly, which will increase the incentive for unscrupulous people to sell synthetic diamonds as if they were natural. to counteract this, we need to develop a very affordable technology that can test stones and protect the consumer. "
The conference was attended by leading representatives of the Association Romande des Métiers de la Bijouterie (ASEMBI ), Diamond Division of the Swiss Gemmological Institute (SSEF), Laboratory GGTL in Switzerland and Liechtenstein, the Gemological Institute of America (GIA), DPA, RJC, as well as organizations such as the société Suisse de Gemmologie (SSG) and the Union Française de la Bijouterie, Joaillerie, Orfèvrerie, des Pierres et Perles.
