What's Happening?
De Beers, a subsidiary of Anglo American, has significantly expanded its diamond exploration efforts in Angola, investing $15 million to date and extending its search to 16 areas. This move positions Angola as the company's largest global diamond exploration focus.
Chief executive Al Cook met with Angolan President João Lourenço, indicating that a successful exploration program could lead to a multi-billion dollar investment in a new diamond mine. De Beers returned to Angola in 2022 after a decade-long absence, signing mineral investment contracts and forming joint ventures with Endiama, Angola’s state-owned diamond company. In 2025, De Beers discovered a new kimberlite field, its first in over 30 years, though further analysis is required to confirm commercial viability. The company has also committed over $15 million to sustainable environmental projects in southern Angola, separate from its exploration budget.
Why It's Important?
This substantial investment by De Beers underscores Angola's growing significance in the global diamond industry. Angola was the world's third-largest rough-diamond producer by volume in 2025, and De Beers' expanded presence could further solidify this position. A successful discovery and subsequent mine development would bring significant foreign investment, create jobs, and boost Angola's economy. For De Beers, finding new, commercially viable diamond deposits is crucial as production declines at older mines globally and as the company navigates market shifts, including competition from laboratory-grown diamonds and fluctuating natural diamond prices. This expansion also occurs amidst uncertainty regarding Anglo American's ownership of De Beers, with Angola having previously expressed interest in acquiring a stake, highlighting broader geopolitical and economic dynamics in the diamond sector.
What's Next?
The immediate next steps involve extensive drilling, laboratory analysis, and geological studies to assess the size, grade, and economic value of the kimberlite discoveries. De Beers aims to transition from early prospecting to production projects if these studies confirm profitable diamond extraction. The company will continue its partnership with Endiama and the Angolan government, which also covers diamond traceability, support for artisanal miners, and international promotion of Angolan stones. A final investment decision on a potential mine will depend entirely on the results of the ongoing exploration work. The outcome of Anglo American's review of De Beers' ownership could also influence future strategic decisions and investment levels in Angola.
Beyond the Headlines
De Beers' renewed focus on Angola reflects a strategic pivot towards underexplored regions with high potential, leveraging modern geological surveys and drilling technology. This move could reshape the global supply chain for natural diamonds, potentially mitigating future supply shortages. Beyond the economic impact, the partnership with Angola includes initiatives for diamond traceability and support for artisanal miners, which could contribute to more ethical and sustainable practices within the diamond industry. The commitment to sustainable environmental projects also signals a broader trend among mining companies to address ecological concerns. This expansion could also empower African diamond-producing nations to exert greater influence over the production and marketing of their natural resources, fostering a more equitable distribution of value within the industry.
