KoBold Starts Development of Zambia Copper Project

Why It Matters

Mingomba will boost Zambia’s position as Africa’s leading copper producer while advancing U.S. goals to diversify critical mineral supply chains away from China.

Key Takeaways

• Project needs $2.4 bn capital, produces 300k tons copper
• Production slated for early 2030s, shaft sinking 2027
• Supports Zambia's goal to triple copper output by 2031
• Backed by Bezos and Gates, uses AI for discovery
• US aims to curb China's mineral supply dominance

Pulse Analysis

KoBold Metals, the venture backed by Jeff Bezos and Bill Gates, has moved from exploration to development on its Mingomba copper project in Zambia. The mine will require roughly $2.4 billion in capital and is designed to deliver about 300,000 metric tons of copper each year once it reaches commercial operation in the early 2030s, with shaft sinking scheduled for early 2027. By securing land for processing facilities, a tailings dam and administrative buildings, KoBold has cleared a major logistical hurdle that many African projects struggle to overcome. At roughly 300,000 tonnes per year, Mingomba ranks among the world’s largest greenfield copper builds.

The timing aligns with Washington’s push to diversify critical mineral supply chains away from China. KoBold’s AI‑driven discovery platform, which identified Mingomba among dozens of prospects, showcases how data‑intensive techniques can de‑risk projects and attract financing in a competitive market. While the company says it can fund early development on its own, it is already in talks with banks and sovereign lenders, signaling that the project could become a flagship example of private‑public partnership in the continent’s mining sector.

Copper demand is set to surge as electric‑vehicle production and renewable‑energy infrastructure expand, and analysts forecast a tightening of supply over the next decade. Zambia’s ambition to lift annual output to three million tonnes by 2031 would make it Africa’s top producer, overtaking the Democratic Republic of Congo, and projects like Mingomba are critical to meeting that target. However, investors must weigh geopolitical risk, infrastructure constraints and potential environmental scrutiny, especially around tailings management, before committing to the multi‑billion‑dollar venture.
