De Beers announces the discovery of a kimberlite field in Angola

De Beers joint venture in Angola announced on Tuesday that it had discovered a kimberlite mine, which is the main source of diamonds. This was its first discovery of this kind in 30 years.

Anglo American is exploring for diamonds with Endiama, the state-owned diamond firm of Angola.

De Beers announced in a press release that the joint venture's first drill hole in July 2025 was kimberlite.

The company stated that further drilling, geophysical survey and laboratory analyses will be carried out over the next few month to confirm the type of kimberlite and assess its diamond-producing potential.

Kimberlites, a rare type of rock that is formed by volcanic eruptions, bring diamonds to the surface.

De Beers, which had left Angola a decade before after unsuccessful explorations, returned in 2022. In April 2022, the mining giant signed mineral investment contracts with Angola's government. This was followed by agreements for diamond processing and exploration.

Anglo American, the parent company of De Beers, is selling it as part its strategy to concentrate on its copper and ore assets.

Sources close to De Beers told the media in June that at least six consortia have expressed interest in De Beers, including Anil Agarwal (the commodities billionaire), Indian diamond firms and Qatari funds. (Reporting and editing by Jan Harvey; Nelson Banya)
