Facing Diamond Slump, Botswana Expands Mining Ties With Gulf and Europe – by Emiliano Tossou (Ecofin Agency – April 17, 2026)

Key Takeaways

• Diamonds represent roughly 70% of Botswana's export earnings
• Debswana cut production 40% from 2023‑2025, deepening recession
• Botswana signed exploration pact with Oman’s Minerals Development Oman
• French talks aim to attract European mining investment beyond diamonds

Pulse Analysis

The diamond market’s recent slump has exposed the fragility of economies that rely heavily on a single commodity. In Botswana, where diamonds underpin roughly 70% of export revenue and a third of the state budget, falling prices and the rise of lab‑grown stones have slashed Debswana’s output by 40% over two years. The resulting double‑dip recession, with GDP contracting 2.8% in 2024 and 0.4% in 2025, has forced policymakers to confront the limits of a mono‑mineral model and seek alternative growth engines.

President Duma Boko’s outreach to the Gulf, highlighted by a joint exploration agreement with Oman’s Minerals Development Oman, reflects a pragmatic pivot toward geological diversification. Oman brings advanced geoscience capabilities and a track record of developing copper, gold and base‑metal projects, offering Botswana a pathway to identify and exploit untapped mineral deposits. The partnership also opens doors to Gulf capital, which is increasingly looking for stable, long‑term investments in Africa’s resource sector, potentially financing infrastructure and downstream processing that can add value locally.

Simultaneously, Botswana’s diplomatic push in Europe, exemplified by recent talks in France, aims to attract European mining firms experienced in large‑scale copper and lithium ventures. By positioning itself as a gateway to Southern Africa’s broader mineral belt, Botswana hopes to capture a share of the global transition to clean energy metals. For investors, the country’s strategic diversification signals a lower risk profile and new opportunities beyond diamonds, while the government’s proactive engagement underscores its commitment to sustainable economic resilience.
