The Group owns Letšeng diamond mine in Lesotho with Head Offices in the United Kingdom and Sales and Marketing capabilities in Belgium and Innovation Solutions in Cyprus. In June 2025, following agreed site rehabilitation and remediation and the Company's application to relinquish the Ghaghoo mining license, the license was officially cancelled and the mine site was formally handed back to the Government of Botswana. The Group has no further obligations or commitments related to the Ghaghoo Mining Licence or the mine site.

The Letšeng mine is renowned for its production of large, top colour, exceptional white diamonds, making it the highest average dollar per carat kimberlite diamond mine in the world.
