Lucara Recovers 1,305-Carat Rough Diamond at Botswana's Karowe Mine

Lucara Diamond Corp. has announced the recovery of an exceptional 1,305.4-carat rough diamond from its Karowe Mine in Botswana, marking the 10th diamond weighing more than 1,000 carats discovered at the mine since production began and reinforcing its status as one of the world's most prolific sources of large, high-value diamonds.

The company said the white rough diamond was recovered intact using its Mega Diamond Recovery (MDR) system, an advanced X-ray technology designed to identify and extract large diamonds without damaging them during processing.

According to Lucara, the diamond was recovered while processing a blend of current open-pit ore and previously mined stockpiled material. As a result, the company cannot conclusively determine whether the stone originated from the active open-pit operation or from the stockpiled ore.

Karowe has established itself as one of the world's premier diamond mines for producing exceptionally large stones. Since operations began, the mine has yielded 10 diamonds exceeding 1,000 carats, including:

Motswedi – 2,488 carats, the second-largest diamond ever discovered.

Lesedi La Rona – 1,109 carats.

Seriti – 1,094 carats.

Eva Star – 1,080 carats.

Commenting on the discovery, William Lamb, President and Chief Executive Officer of Lucara Diamond Corp., said the recovery of the company's 10th diamond exceeding 1,000 carats represents another extraordinary milestone for the Karowe Mine and underscores the unique nature of its world-class ore body.

He noted that no diamond mine in history has consistently produced diamonds of this magnitude, adding that Karowe continues to distinguish itself on the global stage. Lamb also said the latest recovery reinforces the company's confidence in the exceptional value of the resource and supports the continued development of the Karowe Underground Project, which is expected to extend the mine's life and enhance the potential for future discoveries of extraordinary diamonds.

The discovery comes as global diamond producers continue to focus on recovering rare, high-value natural diamonds, despite ongoing challenges facing the broader diamond market in recent years.
