PRESS RELEASE

Lucara Announces the Naming of the 1,758 carat Sewelô Diamond

VANCOUVER, July 18, 2019/CNW/ - (LUC – TSX, LUC – BSE, LUC – Nasdaq Stockholm)

Lucara Diamond Corp. (“Lucara” or the “Company”) is pleased to announce that the winning

submission for the naming of the 1 ,758 carat diamond has been chosen. Meaning “rare find” in

Setswana, the name Sewelô was selected from over 2 2,000 submissions in a contest open to

all citizens of Botswana. The announcement was made during a gala event hosted by Lucara

Botswana in the presence of His Excellency Dr . Mokgweetsi Eric Keabetswe Masisi, President

of the Republic of Botswana . The unbroken 1,758 carat stone was mined from the EM/PK(S)

unit of the South Lobe and was recovered through Lucara’s XRT circuit in April 2019.

Lucara has completed its analysis of the Sewelô Diamond and is considering next steps toward

selling the diamond. Lucara is committed to ensuring that the Sewelô Diamond has a lasting

and positive impact for Botswana and is proud to have once again invited and engaged with

the people of Botswana to choose the name of such an iconic diamond recovered at the Karowe

Mine.

Eira Thomas CEO commented: “ The largest diamond recovered in Botswana’s history was

named by the people of Botswana this evening in a celebration of Botswana’s success. Lucara

is proud to share our achievements with all stakeholders in Karowe and the people of Botswana.

We are in the process of completing an analysis of the Sewelô and we look forward to sharing

the results of this rare find.”
