AT A GLANCE PRODUCING EXCEPTIONAL QUALITY, HIGH VALUE DIAMONDS AIM listed diamond producer Cullinan which operates the Kareevlei Diamond Mine – Exploration one of the top 10 highest value per carat (South Africa) diamond mines in the world Kimberley Finsch KAREEVLEI High calibre local team Koffiefontein with years of experience gained at De Beers and Petra Diamonds recently strengthened by appointment of Michael Houston as Chairman Total material processed Plans to significantly increase 400,000 tonnes, carats recovered 13,000 production in 2019 with further growth expected in 2020 Increasing stone size with FY2018 average grade 3.28 cpht & average value of US$316/c; recently recovered exceptional 8.97c diamond independently valued +$50,000 3 Corporate Presentation Q1 2019

  7. THE RESOURCE INFERRED RESOURCE FOR KV1, KV2, KV3 & KV5 OF 7,744,600 TONNES AND 367,000 CARATS ▪ To date, only 3% of the inferred resource has been mined ▪ Currently mining KV1 and KV2 ▪ Trial mining at KV5 showed that it produces larger, higher value diamonds with an initial estimate of US$411 per carat ▪ Developing plans to start mining the higher grade section of KV3 within the mid term INFERRED RESOURCE NOVEMBER 2018 mine plan Volume Carats Grade Pipe Tonnes (m 3 ) (+1mm) (cpht +1mm) KVW01 605 800 1 561 400 97 000 6.2 ▪ Potential inground value of circa US$100 KVW02 734 000 1 909 700 86 600 4.5 million KVW03 1 461 600 3 629 200 152 000 4.2 KVW05 253 400 644 300 31 400 4.9 TOTAL 3 054 800 7 744 600 367 000 4.7 6 Corporate Presentation Q1 2019

  10. GRADE KV2 - Section 4 (CPHT OF KIMBERLITE) ▪ Of total material mined to-date 80% of ore has been extracted from between surface and 20m below. Grades from this diluted area run between 0 and 3 cpht ▪ Less than 20% of material processed has been at levels below 20m from surface. Grades from this area run up to 6.3 cpht ▪ When mining undiluted kimberlite (typically below 20m) grades are expected to average at pit grade (4.5 cpht KV2 and 6.3 cpht KV1) KV2 - Section 8 ▪ Assuming 400,000 tonnes of kimberlite processed per year (our YE 2019 run rate target) the variation in grade has the following effect (assuming our historic valuation of US$327/carat) on revenues: Grade (cpht) US$ millions 2 2.6 3 3.9 4 5.2 5 6.5 0 – 3 cpht Costs remain unchanged irrespective of grade 4 – 6 cpht (Grade measured by cpht is the weight of diamonds Already mined (carats) found in 100 tonnes of kimberlite) 9 Corporate Presentation Q1 2019

  11. OPERATIONS TO DATE: MINING KV2 DRIVE TO OPEN UP SECOND PIT TO PROVIDE FLEXIBILITY AND DE-RISK SUPPLY OF ORE ▪ Mined 380,000 tonnes to date ▪ 100,000 very low grade 0- 10 m from surface. <1 cpht ▪ 230,000 calcretised kimberlite. 10 – 20m from surface 2 – 3 cpht ▪ 50,000 undiluted kimberlite. 20 – 30m from surface. 4 – 6 cpht ▪ Average grade assuming zero grade in the 0 - 10m level is 3.5 cpht ▪ Expect future mining to be in +4 cpht ▪ Grade so far varies between 1.1 cpht to 6.3 cpht ▪ This variation is expected whilst mining the near surface section ▪ Average grade increases when mining undiluted kimberlite at the sub 20m level 10 Corporate Presentation Q1 2019

  12. OPERATIONS TO DATE: MINING KV1 DRIVE TO OPEN UP SECOND PIT TO PROVIDE FLEXIBILITY AND DE-RISK SUPPLY OF ORE ▪ Commenced stripping in April 2018 ▪ 340,000 tonnes of waste removed ▪ 55,000 tonnes kimberlite processed ▪ Inferred resource of 1.56m tonnes ▪ Resource modelled to 65m below surface ▪ Total mineable resource likely to be much greater ▪ Inferred grade of 6.2 cpht, 40% higher than KV2 ▪ 40m from KV2 at closest point which will enable mining both pipes as one pit, saving costs ▪ 10.58c diamond recovered ▪ Sold in October 2018 for US$74,557 ▪ Third largest stone by size and value ever mined at Kareevlei ▪ Pleasing that it has come from near surface ground 11 Corporate Presentation Q1 2019

  13. OPERATIONS TO DATE: THE PLANT Historic Tonnage Processed 200000 ▪ Plant utilisation of 73% 150000 ▪ Poor design and layout Tonnes 100000 ▪ Non-standardisation of 50000 components 0 2014 2015 2016 2017 2018 ▪ Identified bottleneck with Year crushing circuit ▪ Augmenting current skill base ▪ Continual improvement ongoing 12 Corporate Presentation Q1 2019

EVALUATION AND EXECUTING OF DEVELOPMENT PLAN PIT EVALUATION Phase 1 Phase 2 Phase 3 ▪ KV3 ▪ 4 to 5 year mine plan to ▪ Flexibility during this period to extract 2m tonnes ore from switch to 70m push back ▪ Total mineable resource of ▪ combined KV1 and KV2 Strip ration increases 3.6m tonnes ▪ Extends pits by 1 to 2 years (400,000t per year, 300,000 to ▪ Total surface area of 5.5 ha 350,000t for 2019) ▪ Depending on grade a further ▪ 50m push back allowing ▪ 250m from plant push back to 100m is possible mining to 70m below ▪ Higher strip ratio ▪ North segment of specific surface interest ▪ Geology similar to KV1 and KV2 ▪ Inferred grade ▪ 4.2 cpht ▪ Mining to 70m will provide a further 8 years extra Life of Mine 13 Corporate Presentation Q1 2019
