De Beers and Angola’s national diamond company, Endiama, have announced the discovery of a kimberlite—the primary host rock for diamonds—marking a significant breakthrough in their joint exploration efforts.
The discovery was made in July 2025 when the De Beers-Endiama joint venture intersected kimberlite in its first drill hole into a high-priority target cluster, identified from airborne surveys completed earlier in March.
This find represents the first new kimberlite field discovered by De Beers Group in over 30 years.
Further drilling, ground geophysical surveys, and laboratory analysis will now be conducted to determine the kimberlite’s characteristics and diamond-bearing potential.
The milestone builds on two Mineral Investment Contracts signed between De Beers and the Angolan government in April 2022, as well as a Memorandum of Understanding inked at Mining Indaba in February 2024.
These agreements solidify a long-term partnership aimed at responsibly developing Angola’s diamond resources.
De Beers chief executive Al Cook hailed the discovery as a testament to Angola’s diamond potential and the strength of collaboration.
“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.
“It is a powerful reminder of what can be achieved through partnership, and I commend President Lourenco and his government for all the work they have done to enhance transparency, adopt international best practices, and create a business friendly environment, all of which has enabled us to return to Angola and seek new sources of supply.”
