During FY 2022 the Board approved an extension project of CC1 East: We are monitoring these changes together with options to mitigate the grade differential.įY 2022 total production was 4.9 million tonnes, 1.8 Mcts. Recovered ROM grade was 36.2cpht in FY 2022, within guidance despite a decline towards the end of the Year due to a change in the composition of ore within the C-Cut block cave resulting in a higher proportion of lower-grade and greater-density ore. The Cullinan Mine contains a world-class gross resource of 147.2 Mcts as at 30 June 2022, which suggests its mine life could be significantly longer than the current mine plan to 2030. Many of the world’s most famous diamonds herald from the Cullinan Mine, and it continues to produce world-class diamonds under Petra’s stewardship. The mine earned its place in history with the discovery of the Cullinan diamond in 1905, the largest rough gem diamond ever found at 3,106 carats, which was cut to form the two most important diamonds in the British Crown Jewels. The Cullinan Mine is renowned as a source of large, high-quality gem diamonds, including Type II stones, as well as being the world’s most important source of very rare blue diamonds.
