This marks the first new kimberlite field discovery for De Beers in over 30 years and signals a significant development for Angola, which has explored only around 40% of its diamond-rich territories.

The find follows De Beers’ return to Angola in 2022, after earlier exploration efforts between 2005 and 2012 yielded limited success. Under new mineral investment contracts with the Angolan government, the company focused its efforts in the northeast, conducting geological surveys, aerial electromagnetic studies, and prospecting work.

By late 2024, De Beers had identified eight high-potential kimberlite targets from airborne survey data. In July 2025, the De Beers–Endiama joint venture intersected kimberlite in its first drill hole into a high-priority target cluster.

“This breakthrough represents the discovery of the first new kimberlite field by De Beers Group in more than three decades,” the companies said in a joint statement issued on 12 August. “Over the coming months, further drilling, ground geophysical surveys, and laboratory analysis will be conducted to confirm the kimberlite type and assess its diamond potential.”
