Lucapa Diamond Company Limited Provides Lulo Alluvial Resource Update Lucapa Diamond Company Limited refers to the announcement released on 10 April 2025 titled "Lulo Alluvial Resource Update increases carats by 9% at modelled value of USD 1,581/ct". The total diluted volume of gravel available for mining in the Lulo Alluvial Resource increased by 15% to 5.8Mm3, maintaining the equivalent of at least eight years of production at Lulo's planned mining and processing capacities. Extensive resource definition work involving 7,197 auger drill holes and 150 pits, including drilling in Mining Blocks 129 and 137 in the south (Maps 1-3);. These data are predominantly based on mining results. No metallurgical recovery factors are applied as the data has been generated using actual production results. Information included in this announcement that relates to exploration results and resource estimates is based on and fairly represents information and supporting documentation prepared and compiled by Richard Price MAusIMM who is a Member of the Australasian Institute of Mining and Metallurgy. Mr. Price has sufficient experience which is relevant to the style of mineralisation and type of deposit under consideration and to the activity which he is undertaking to qualify as a Competent Person as defined in the 2012 Edition of the Australasian Code for Reporting Exploration Results, Mineral Resources and Ore Reserves. Reporting of diamond exploration results and diamond resource estimates for the Lulo concession. Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material., Material is recovered from the auger flights and used to measure depth and thickness of the gravels., The drilling is used to measure gravel thickness only. Core (or costean, channel, etc.) photography., The total length and percentage of the relevant intersections logged., Drilled material is recovered from the auger flight and used to measure depth and thick of the gravels., Sample pits are lithologically logged and measured to determine gravel thickness., Logging is semi-quantitative with edge thicknesses measured of the entire pit. The process is identical to that which would be used for commercial mining and results are considered representative. Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. 6,199 pits have been completed in total during the project. Other data required in the Code is not material and its exclusion does not detract from the understanding of the Resource Report. Bulk sampling and production results were included in the Lulo Diamond Resource estimate. The estimated areal grade in stones per hundred metres squared (sphm2) and average stone size as carats per stone (cts/stn) are determined using all available diamond data within each block These data are predominantly based on Mining results. If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. Diagrams, Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported. These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views., Appropriate maps for the reported mineralisation with scale and north points are included in Maps 1-3., Balanced reporting, Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results., Several blocks have gravel volume estimates based on thickness measurements but have not been included in the Lulo Diamond Resources due to insufficient information related to diamond content., Other substantive exploration data, Other substantive exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples - size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances., The data from the auger drilling and pitting programs has allowed the definition of alluvial channels, which has been followed by the Lead Author of the Resource Report and Independent Competent Person were undertaken in January 2015 and August 2018. If a computer assisted estimation method was chosen include a description of computer software and parameters used. If a description of computer software and guidelines include a description of computer software & parameters used. The availability of check estimates, previous estimates, previous estimates and parameters used. The availability of computer software and whether the availability of computer assisted estimation method of computer software and/or mine production records and parameters used.

Lucapa Diamond Company Limited Announces an Updated JORC Classified Inferred Alluvial Diamond Resource for the Lulo Diamond Concession in Angola Lucapa Diamond Company Limited announced an updated JORC Classified Inferred Alluvial Diamond Resource (Lulo Alluvial Resource) for the Lulo diamond concession in Angola. The Lulo Alluvial Resource has grown to 249,000 carats, representing a 9% increase compared to the prior period (228,400 carats) and the seventh consecutive year in which resource carats have increased. The total diluted volume of gravel available for mining in the Lulo Alluvial Resource increased by 15% to 5.8Mm3, maintaining the equivalent of at least eight years of production at Lulo's planned mining and processing capacities. The updated Lulo Alluvial Resource was estimated after taking into account: Mining depletion to 31 December 2024 by SML mining operations, during which time 25,341 carats of diamonds were recovered; Extensive resource definition work involving 7,197 auger drill holes and 150 pits, including drilling in Mining Blocks 129 and 137 in the south (Map 1); Sales of diamonds during 2024 totaling USD 54.5m at an average diamond price of USD 1,980/carat. Information included in this announcement that relates to exploration results and resource estimates is based on and fairly represents information and supporting documentation prepared and compiled by Richard Price MAusIMM who is a Member of the Australasian Institute of Mining and Metallurgy. Mr. Price is an employee of Lucapa Diamond Company Limited. Mr. Price has sufficient experience which is relevant to the style of mineralisation and type of deposit under consideration and to the activity which he is undertaking to qualify as a Competent Person as defined. in the 2012 Edition of the Australasian Code for Reporting Exploration Results, Mineral Resources and Ore Reserves. Subject to any continuing obligations under applicable law and ASX Listing Rules, the Company does not undertake any obligation to update or revise any information. Reporting of diamond exploration results and diamond resource estimates for the Lulo concession. JORC Code (2012) requirements - Sampling Techniques and Data.
