Mixed Fortunes for DRC Minerals as Copper, Gold, and Tin Prices Decline While Tantalum Gains

Why It Matters

The price shifts directly affect DRC’s export revenues and its role as a critical supplier of minerals for global manufacturing and the clean‑energy transition, influencing investment and policy decisions in the sector.

Key Takeaways

• Copper falls $115 per tonne, price pressure persists
• Gold down $3.49/kg, marginal decline continues
• Tantalum jumps $94.60/kg, electronics demand drives surge
• Cobalt stable at $55,600/t after export lift
• Aluminum gains modestly, indicating steady industrial demand

Pulse Analysis

The Democratic Republic of the Congo’s weekly mineral price bulletin for March 23‑28 2026 shows a broad slide in several of its flagship commodities. Copper, the country’s top export, slipped to $12,718 per tonne, a $115 decline from the previous week, echoing weaker industrial demand and softer global metal cycles. Gold and zinc also posted modest drops, while tin, silver and nickel each edged lower. These movements underscore how tightly DRC’s export revenues are tied to the volatility of international markets, especially as the mining sector grapples with fluctuating macro‑economic signals.

Exporters will watch the upcoming IMF commodity outlook for clues on price recovery. In contrast, tantalum broke the downward trend, climbing to $717 per kilogram—an increase of roughly $95 week‑over‑week. The surge reflects sustained demand from the electronics industry, where tantalum’s high capacitance and corrosion resistance remain essential for smartphones, automotive sensors and emerging 5G infrastructure. Aluminum also posted a modest rise to $1,635 per tonne, signalling that broader industrial activity, particularly in construction and packaging, continues to support base‑metal consumption despite the broader metal slowdown. Higher tantalum prices also improve margins for DRC miners, encouraging further exploration.

Cobalt, a strategic battery metal, held steady at about $55,600 per tonne after the Congolese regulator lifted a temporary export suspension in October 2025. The policy reversal has helped preserve market confidence and keeps DRC’s cobalt output flowing to electric‑vehicle manufacturers and renewable‑energy storage projects worldwide. As the clean‑energy transition accelerates, the country’s ability to maintain stable cobalt pricing while navigating price swings in other commodities will be crucial for sustaining foreign exchange earnings and attracting continued investment in its mining infrastructure. Long‑term contracts with major automakers could buffer future price volatility.
