De Beers announces kimberlite field discovery in Angola
Aug 12 (Reuters) – De Beers’ joint venture in Angola has discovered a new kimberlite field, the most common source of mined diamonds, it said on Tuesday, its first such discovery in three decades.
The Anglo American (AAL.L), opens new tab unit is jointly exploring for diamonds in Angola in partnership with the country’s state-owned diamond company Endiama.
De Beers said in a statement the joint venture had hit kimberlite in its first drill hole into a high-priority cluster of targets in July 2025.
The company said further drilling, geophysical surveys and laboratory analysis will be conducted over the next few months to confirm the kimberlite type and assess its diamond potential.
Kimberlites are a rare rock type that brings diamonds to the surface through volcanic eruptions.
De Beers returned to Angola in 2022, having left a decade earlier after exploring unsuccessfully. The mining giant signed two mineral investment contracts with the government of Angola in April 2022, followed by agreements on diamond processing and exploration in 2024.
