The feasibility study is vital in securing Karowe’s lifespan past its current 2026 open pit lifespan by at least another 10 years.
The EM/PK(S) is a higher grade and has larger diamonds – source of Lesedi La Rona, Constellation diamonds and the 1,758carat diamond recovered in April 2019.
At least 51% of the remaining South Lobe recoverable indicated carats and 35% of the tonnage is attributable to the EM/PK(S) unit, in comparison with 12% carats and 8% tonnage from the previous estimate.
Meanwhile, Lucara said it is projected to rake in between $170 million and $200 million in revenue from the sale of between 300 000 carats and 320 000 carats.
The company was also set to produce between 300 000 carats and 330 000 carats this year.
