Lucara Diamond has awarded the critical lateral development contract for its Karowe underground expansion project (UGP) to Group R Mining and Exploration Botswana, marking a significant milestone in the mine's transition from open-pit to underground operations.
The contract covers all underground lateral development work from the production and ventilation shafts to the orebody, including construction of the extraction level, underground crushing chamber, fine ore bins, pump stations, and associated infrastructure.
"We are pleased to announce the award of this critical Contract to Group R, marking an important milestone in the continued development of our underground project,” said Lucara president and chief executive William Lamb.
“The award of the last major contract for the UGP reflects our commitment to maintaining momentum on the Project and delivering the Project safely, responsibly, and in accordance with our schedule."
Group R chief executive Hannes van Staden said they are honoured to partner with Lucara on this crucial phase of the Karowe underground project.
“Our team is dedicated to upholding the highest standards of safety, quality, and operational excellence as we collaborate to open the next chapter of this world-class asset," he said.
Group R is expected to mobilise in the second quarter of 2026, with lateral development work commencing in July 2026.
The Karowe underground project is designed to extend the mine's life and maintain its position as a leading producer of large, high-quality diamonds.
