Lucapa Diamond Company Limited - 41 DIAMONDS INCLUDING TWO SPECIALS RECOVERED FROM LULO KIMBERLITE L164 BULK SAMPLE

Lucapa Diamond Company Limited (ASX: LOM) ('Lucapa' or 'the Company') together with our Project Lulo partners, Endiama and Rosas & Petalas, are pleased to advise that the results from the completed processing of bulk sample KBS/164/01 from Lulo kimberlite L164 have confirmed that it is a primary source hosting Special sized diamonds.

Lulo kimberlite bulk sample KBS/164/01, totalling ~2,200 in-situ m3 or ~5,641 wet tonnes of kimberlite material, has returned a total of 41 diamonds weighing 66.05 carats, including two Special sized diamonds weighing 15.27 and 12.37 carats (total of 27.64 carats or ~42% of the total weight) with 12 diamonds greater than one carat recovered (total of 50.21 carats or ~76% of the total weight). This yielded an average grade of ~3.00 carats per one hundred cubic metres ('cphm3 ') or ~1.17 carats per one hundred tonnes ('cpht') and an average stone size of ~1.61 carats (at a bottom cut of screen size of 1.5mm).

Lucapa Managing Director, Stephen Wetherall said, 'We are delighted with the result and recovery of Special sized diamonds from this Lulo kimberlite sample. The Lulo kimberlite exploration program has delivered tangible proof that the Lulo kimberlite province hosts primary sources containing Specials, confirming Lucapa's and our partner's long held views. Preliminary indications are that the kimberlite deposit has a very coarse (large) average stone size of 1.61 carats which, compares very favourably to two of the coarsest primary source kimberlites globally, the Mothae and LetSeng mines in Lesotho.'

The varying size frequency distributions and the differing diamond characteristics from the many alluvial diamond mining blocks continue to provide evidence that there are multiple primary sources contributing to the secondary alluvial resource on the Lulo concession. The methodical approach to the exploration program will continue with the processing of all the kimberlites on the priority list in order to ensure that all large stone bearing kimberlites are identified and taken to the next stage of evaluation. Kimberlite L164 is located south (upstream) of the Canguige Catchment area and was placed on the priority kimberlite bulk sample list due to its indicator mineral content.

ABOUT LUCAPA

Lucapa is an ASX listed diamond miner and explorer with assets in Africa and Australia. It has interests in two producing diamond mines in Angola (Lulo, in which LOM holds 40%) and Lesotho (Mothae, in which LOM holds 70%). The large, high-value diamonds produced from these two niche African diamond mines attract some of the highest prices per carat for rough diamonds globally. The Lulo mine has been in commercial production since 2015, while the Mothae mine commenced commercial production in 2019. In 2021, through its wholly owned subsidiary, Australian Natural Diamonds Pty Ltd, Lucapa completed the strategic and transformative acquisition of the Merlin Diamond Project, an historic Australian mine in the Northern Territory of Australia. A feasibility study is expected to be completed in Q1 2023. Lucapa and its project partners are also exploring for potential primary source kimberlites or lamproites at the prolific Lulo concession in Angola, the Brooking and Merlin projects in Australia and the Orapa Area F project in Botswana. The Board, management and key stakeholders in Lucapa have deep global diamond industry experience and networks all through the value chain from exploration to retail.
