The company’s social investments and export concentration also signal broader economic and development implications for the region.

Key Takeaways

• Chitotolo holds 7.46 million carats, supporting 20+ years of mining
• 2025 production hit 331,000 kg, 6% above target
• Revenue fell to $150 million despite higher output
• Dubai absorbs 97.7% of exports, local processing at 2.3%

Pulse Analysis

Angola’s diamond sector has long been a cornerstone of its export earnings, and the Chitotolo Mine stands out as a strategic asset. With an estimated 7.46 million carats in proven reserves, the operation can theoretically continue for more than 20 years at current extraction rates. This longevity places Chitotolo among the continent’s most sustainable diamond projects, offering investors a rare blend of resource depth and operational stability that can buffer against short‑term market swings.

Despite a 6% production boost in 2025, Chitotolo’s revenue declined to roughly $150 million, underscoring the impact of volatile international diamond prices. The company’s capital spending also contracted, dropping to $8 million after a $11 million outlay in 2024, suggesting a cautious approach to expansion amid uncertain pricing. Nevertheless, the mine contributed $7.5 million in royalties, reinforcing its fiscal importance to the Angolan state and highlighting the sector’s role in public‑budget diversification.

Export dynamics reveal a heavy reliance on the Dubai market, which absorbs 97.7% of Chitotolo’s diamonds, while domestic cutting facilities account for a modest 2.3% of sales. This concentration exposes the mine to geopolitical and trade‑policy risks, prompting the firm to explore value‑addition locally. On the social front, Chitotolo employs over a thousand workers—89% nationals—and has earmarked $2.8 million for health and education, including a new clinic slated for 2027. Addressing gender balance and retaining female geologists remain challenges, but the company’s community investments signal a broader commitment to sustainable development in the region.
