In a breakthrough for Angola’s diamond sector, London-based mining giant De Beers has announced the discovery of a new kimberlite field — the company’s first such find in more than three decades.
The discovery, made in July 2025 through its joint venture with Angola’s state-owned diamond firm Endiama, is a result of airborne surveys conducted earlier this year.
Kimberlites, a rare volcanic rock that transports diamonds from deep within the Earth to the surface, are the primary sources of mined diamonds. The newly intersected kimberlite lies in a high-priority target zone identified using advanced geophysical techniques. “Angola is, in our view, one of the best places on the planet to look for diamonds, and this discovery reinforces our confidence,” said Al Cook, CEO of De Beers Group. He also praised the Angolan government’s efforts to improve transparency and foster international investment in mining.
The find stems from two mineral investment contracts signed in 2022 and a Memorandum of Understanding signed in 2024. It comes at a time when parent company Anglo American is preparing to divest De Beers to shift its focus on mining copper and iron ore, with multiple buyers reportedly expressing interest, including the Government of Botswana. Exploration will continue with further drilling and lab analysis to assess the diamond potential of the site.
If commercially viable, the field could bolster Angola’s economy and help stabilize global diamond supply amid tightening reserves and rising demand. “We are excited about the role De Beers can play in helping the country deliver on its huge potential, both below and above the ground,” Al Cook added.
