Lucara Recovers 470 Carat Diamond from the Karowe Mine in Botswana

470 carat diamond recovered from the Karowe Mine in Botswana

Lucara Diamond Corp. is pleased to announce the recovery of a 470 carat top light
brown clivage diamond from its 100% owned Karowe Diamond Mine located in Botswana.

The diamond, measuring 49x42x26mm, was recovered from direct milling of ore sourced from the EM/PK(S) unit of the
South Lobe. The 470 carat recovery forms a notable contribution to a series of top quality gem and clivage quality
diamond recoveries during a recent production run, including an additional 5 diamonds greater than 100 carats
(265ct, 183ct, 161ct, 116ct, 106ct) and 13 diamonds between 50 and 100 carats in weight.

The May production run, dominated by EM/PK(S) ore, produced diamonds greater than 10.8 carat in weight accounting for 12.7% weight percent of total production, exceeding resource expectations. Continued strong resource performance and recovery of large diamonds reinforces the significance of the EM/PK(S) as an important economic driver for the proposed underground mine at Karowe.


The 470 carat diamond was recovered in the Coarse XRT circuit and represents the third +300 carat diamond
recovered to date in 2021. Year to date, Karowe has produced 10 diamonds greater than 100 carats including 6
diamonds greater than 200 carats, including the 341 carat (link to press release) and 378 carat (link to press release)
top white diamonds recovered in January 2021.
