Moreover, Lucapa and its partners – Angola’s national diamond company Endiama, and Rosas & Petalas – have commenced commissioning of the modules for the new XRT diamond processing and recovery stream.

The XRT technology and larger screens (55 mm) will, as part of the new processing stream at the 150 tph diamond processing plant, provide capacity to recover individual diamonds of up to 1 100 carats.

The XRT technology is also more efficient at recovering low-luminescing Type IIa diamonds.

To ensure grade and source integrity, the oversize material that has been stockpiled since February 2016, which now stands at about 19 000 bcm, will be managed and processed through the new XRT stream, over time, in batches separate to the ongoing oversize material recvovered and processed from daily mining operations at Lulo.

Lucapa has to date recovered more than 30 +50 carat diamonds and 6 +100 carat diamonds
