This week, the Canadian diamond miner announced it recovered a 1,080.1-carat Type IIa from the Karowe mine in Botswana.
The diamond measures 82.2mm by 42.8mm by 34.2mm. Lucara said the “top” white stone is “high quality.”
It was recovered in the Coarse XRT unit from direct milling of ore from the M/PK(S) unit located in the South Lobe.
The South Lobe has produced four diamonds weighing more than 1,000 carats since 2015.
Others were a 1,174-carat diamond in 2021, the 1,758-carat Sewelô diamond in 2019, and the 1,109-carat Lesedi La Rona in 2015.
“As we progress mining deeper in the open pit and transition to underground mining, exclusively in the South Lobe, the preponderance of large, high value stones is increasing, consistent with the resource model and underpins the strong economic rationale for investing in the Underground expansion that will extend the mine-life out to at least 2040,” remarked Lucara CEO Eira Thomas.
Lucara owns the Karowe mine in its entirety. It has been in production since 2012.
