The De Beers Group, in partnership with Angola’s national diamond company, Endiama, has confirmed the discovery of a new kimberlite field in Angola — the host rock for diamonds — marking the first such find by De Beers in over three decades.
The breakthrough occurred in July 2025 when the joint venture intersected kimberlite in its first drill hole into a high-priority cluster of targets. These targets were identified through airborne geophysical surveys conducted in March 2025. The find represents a pivotal moment in the partnership’s exploration efforts and offers potential for further development, although the diamond content and commercial viability are yet to be established.
Further exploration work, including drilling, ground geophysical surveys, and laboratory analysis, is set to take place in the coming months to determine the kimberlite type and assess its diamond potential.
The discovery builds upon the framework established by two Mineral Investment Contracts signed in April 2022 between De Beers and the Government of Angola, along with a Memorandum of Understanding signed at Mining Indaba in February 2024. These agreements reflect a mutual commitment to responsibly developing Angola’s diamond resources under improved transparency measures and adherence to international best practices.
Al Cook, Chief Executive Officer of De Beers Group, emphasised Angola’s geological potential and praised the Angolan government’s reforms in creating a business-friendly environment. “Angola is, in our view, one of the best places on the planet to look for diamonds, and this discovery reinforces our confidence,” he said, highlighting the role of public-private partnerships in unlocking natural resource potential.
Angola ranks among the world’s top diamond-producing nations, with the majority of its production historically sourced from alluvial deposits. The identification of a new kimberlite field — potentially hosting primary diamond sources — could represent a significant step forward in diversifying and expanding the country’s production base.
This development comes at a time of heightened interest in African diamond reserves, as global supply constraints and shifting market demands prompt mining companies to seek new deposits. While the commercial prospects of the newly discovered field remain to be confirmed, the find underscores the geological promise of Angola’s underexplored regions.
