Since commissioning of the XRT circuit in 2015, a total of 12 diamonds in excess of 300 carats have been recovered at Karowe, including 2 greater than 1,000 carats, from a total production of approximately 1.4 million carats. Of the 12 +300 carat diamonds recovered, 50% were categorized as gem quality with 11 sold to date generating revenue in excess of US$158 million.   

Eira Thomas, Lucara's CEO commented: "Lucara's technologically advanced, XRT diamond recovery circuit has once again delivered historic results. Karowe has now produced two diamonds greater than 1,000 carats in just four years, affirming the coarse nature of the resource and the likelihood of recovering additional, large, high quality diamonds in the future, particularly as we mine deeper in the orebody and gain access to the geologically favourable EM/PK(S) unit, the source of both of our record breaking, +1,000 carat diamonds."

This press release has been reviewed and approved by Dr. John Armstrong, Ph.D. P.Geol., Vice-President, Technical Services of the Company and a "Qualified Person" for the purposes of National Instrument 43-101.
