De Beers, in partnership with Angola’s state-owned Endiama, has discovered a new kimberlite field, its first in 30 years, following initial drilling in a high-priority target cluster. Kimberlite is the primary source of mined diamonds, and further drilling, geophysical surveys, and lab analysis will determine diamond potential. De Beers re-entered Angola in 2022 after a decade-long absence, signing mineral investment contracts in 2022 and diamond processing agreements in 2024.
