Lucara Diamond Corp. has recovered an unbroken 998 carat high white clivage diamond from its Karowe mine in Botswana. The diamond, measuring 67x49x45mm, was recovered from direct milling of ore sourced from the EM/PK(S) unit of the South Lobe of Karowe. Lucara has made several high-quality recoveries lately, including a number of top quality clivage and gem quality stones.
According to Eira Thomas, CEO of Lucara, the EM/PK(S) is an important economic driver for the proposed underground mine at Karowe and continues to produce large gem quality diamonds in line with expectations, a further testament to the strong resource performance at Karowe.
The 998-carat diamond was recovered in the MDR (Mega Diamond Recovery) XRT circuit that allows for diamond recovery post primary crushing and prior to milling. This recovery represents the second +500 carat diamond recovered from this circuit in 2020. Year to date, Karowe has produced 31 diamonds greater than 100 carats including 10 diamonds greater than 200 carats comprising of the 549 carat Sethunya, and the 998 carat diamond.
Eira Thomas, CEO commented: “Lucara is extremely pleased with the continued recovery of large high quality diamonds from the South Lobe of the Karowe mine.” To recover two +500 carat diamonds in 10 months along with the many other high quality diamonds across all the size ranges is a testament to the unique aspect of the resource at Karowe and the mine’s ability to recover these large and rare diamonds. Operations at Karowe have continued through 2020 and operational challenges, due to Covid-19 restrictions, have been met with professionalism by the team. “We look forward to a safe finish to 2020 and continued success at Karowe as we remain focused on strong operations to ensure maximum resource performance,” says Thomas.
