Lucapa Diamond Company, the Sydney-listed diamond producer and exploration firm, had started commissioning the modules for the new state-of-the-art XRT processing and recovery stream, a move they announced last summer. The he XRT technology and larger screens (55 mm) recovery and sorting solution will allow recovery of diamonds of up to 1,100 carats. This is the same technology Lucara Diamond used to recover the 1,109-carat Lesedi La Rona. The company also says the XRT technology is more efficient at recovering low-luminescing Type IIa diamonds. Lulo has already delivered six diamonds weighing more than 100 ct and yielded a record 404 ct diamond in February. Following the discovery of that diamond, the Lulo mine partners secured the XRT module and started stockpiling oversized material. The stockpile of 19,000 bulk cubic metres will be processed through the new XRT stream over time.
It has also added the recovery of another two large diamonds weighing 77 and 71 carats that they will sell in December along with the stones of 172, 104 and 72 carats announced last week. As with all previous Lulo diamond sales, the sales will be conducted in Luanda by the Angolan government’s diamond marketing division, Sodiam.
