NEWS RELEASE

LUCARA RECOVERS EPIC 2,492 CARAT DIAMOND FROM THE KAROWE MINE

VANCOUVER, B.C., August 21, 2024 /CNW/ (LUC – TSX, LUC – BSE, LUC – Nasdaq Stockholm)

Lucara Diamond Corp. (“Lucara” or the “Company”) is thrilled to announce the recovery of an exceptional 2,492 carat

diamond from its Karowe Diamond Mine in Botswana. This remarkable find, one of the largest rough diamonds ever

unearthed, was detected and recovered by the Company's Mega Diamond Recovery (“MDR”) X-ray Transmission (“XRT”)

technology, installed in 2017 to identify and preserve large, high -value diamonds. The stone was recovered from the

processing of EM/PK(S) kimberlite, the dominant ore type that Lucara will continue to target during the first years of

the Company’s underground mining operations.

This discovery underscores Karowe's reputation as a world -class asset and reaffirms Lucara's position as a leading

producer of large, exceptional diamonds. This latest recovery joins an impressive roster of other significant finds from

the mine, including the 1,758 carat Sewelô and the 1,109 carat Lesedi La Rona.

William Lamb, President and CEO of Lucara, commented on this historic discovery: "We are ecstatic about the recovery

of this extraordinary 2,492 carat diamond. This find not only showcases the remarkable potential of our Karowe Mine,

but also upholds our strategic investment in cutting -edge XRT technology. The ability to recover such a massive, high -

quality stone intact demonstrates the effectivene ss of our approach to diamond recovery and our commitment to

maximizing value for our shareholders and stakeholders."

Mr. Lamb added, "This discovery reinforces Karowe's position as a truly world -class diamond mine and highlights the

continued success of our operational and underground development strategy. ”

Botswana’s diamond industry delivers wide-ranging socio-economic benefits to the country that extend well beyond

the mining sector. Its influence supports national development by funding critical areas such as education and

healthcare.

This discovery symbolizes Botswana's continued ascent as a global leader in diamond production. It represents not only

the unparalleled wealth found in Botswana's soil, but also the remarkable progress the nation has made in developing

its diamond industry for the benefit of its citizens.

This news release has been reviewed and approved by Dr. Lauren Freeman, PhD. Pr. Sci. Nat., Vice-President, Mineral

Resources of the Company and a "Qualified Person" for the purposes of National Instrument 43 -101.

On behalf of the Board,

William Lamb

President and Chief Executive Officer
