De Beers, in collaboration with Angola’s national diamond company Endiama, has revealed a major geological breakthrough—the discovery of a new kimberlite field in northeastern Angola, a promising indicator of potential diamond deposits.
This marks De Beers’ first kimberlite field discovery in over 30 years and signals a major milestone for Angola’s diamond sector, where only around 40% of the country’s mineral-rich lands have been explored to date.
In a joint announcement released on August 12, the companies described the find as “a significant step forward” in their renewed exploration campaign. Kimberlite, the volcanic rock that often hosts diamonds, was successfully intersected in July 2025 during initial drilling of a high-priority target zone identified through airborne geophysical surveys conducted in March.
De Beers initially returned to Angola in 2022 after a previous exploration phase (2005–2012) yielded limited results. The company re-engaged with Angola under new mineral investment contracts, focusing on two license areas in Lunda Sul province—an area long known for its diamond potential.
Over the past year, De Beers has carried out comprehensive geological fieldwork, including aerial electromagnetic surveys and ground-based prospecting. By late 2024, the company had pinpointed eight promising kimberlite targets.
The newly discovered field, located within a cluster of these targets, now enters a more intensive phase of evaluation. Over the coming months, the joint venture will carry out further drilling, ground-based geophysical assessments, and detailed laboratory analysis to determine the nature of the kimberlite and its diamond-bearing potential.
This discovery reinforces Angola’s position as a rising force in the global diamond industry and reaffirms De Beers’ long-term confidence in the region’s untapped resources.
