After receiving approval from the Botswana Department of Environmental Affairs, triple-listed Lucara Diamond Corp is ready to proceed with extracting a bulk sample from one of two high-potential exploration licenses located on trend with the company’s flagship Karowe mine.
The licenses, awarded in 2014, were believed to host at least three known diamondiferous kimberlites – BK02, AK11 and AK12 – and the company advised that it was ready to move forward with more in-depth exploration work on BK02 in November.
“The receipt of the permits is a positive step forward in our resource extension campaign. We are excited about the prospects of these licenses based on the historical work conducted on the property,” president and CEO William Lamb stated.
Lucara said it had completed building and commissioning a bulk sample plant for use during the 5,000 ton campaign and first results were expected before year-end as the company had already awarded mining and transport contracts, with earthmoving equipment expected to be mobilized to the BK02 kimberlite within the next two weeks. Initial work would involve removing the overburden and trenching, to determine the optimal sample areas before extraction started and advised that applications were in progress for bulk sample extraction from the AK11 and AK12 kimberlites, along with the required permits to allow drilling on the respective sites.
The Karowe mine is listed in mines that had produced the largest diamonds with a rough stone (uncut) weight of over 200 carats (40 grams) and has probable reserves to a depth of 324 m of 33.1 mt containing 5.1 million carats with remaining indicated resource from surface to a depth of 400 m of 48.07 mt containing 7.61 million carats. There is an inferred resource from 400 m to 750 m of 21 mt containing 3.04 million carats. The Mine is based on the AK6 kimberlite pipe, which is part of the Orapa Kimberlite Field (“OKF”) in Botswana. The bedrock of the region is covered by a thin veneer of wind-blown Kalahari sand and exposure is very poor. Rocks close to surface are often extensively calcretised and silcretised due to prolonged exposure on a late Tertiary erosion surface (the African Surface) which approximates to the present day land surface.
