Copper Intelligence–CoTec DRC tailings JV: project and process notes for mine engineers
Reviewed by Tom Sullivan

First reported on MINING.com
30 Second Briefing
Copper Intelligence and CoTec Holdings have formed a British Virgin Islands joint-venture company to process historical copper tailings across the Democratic Republic of Congo’s legacy copper districts, which have generated waste since the 1950s. CoTec will deploy its extraction technologies for rare earth and strategic materials to upgrade old tailings and redundant copper deposits, while Copper Intelligence provides regional execution capability and targets high-potential DRC assets. Projects will be advanced asset-by-asset, subject to detailed legal and technical due diligence and board approvals, with scale-up funding sought from the US International Development Finance Corporation and others.
Technical Brief
- Target area is the DRC’s legacy copper districts that have generated tailings continuously since the 1950s.
- CoTec’s extraction technologies are configured for rare earths and strategic materials, repurposed here for copper-bearing tailings.
- Asset selection will proceed tailings facility by tailings facility, each requiring separate binding development agreements.
- Governance requires approvals from independent members of both the JV and CoTec boards before committing capital.
- Two third‑party investment vehicles linked to CoTec’s CEO and chairman are formal parties to the JV structure.
- Copper traded up about 9% in September, hitting a record price of $14,875 earlier in the month.
- Market valuations at announcement: Copper Intelligence about $1.2 billion; CoTec roughly C$150.5 million (~$106 million).
Our Take
Within our 1245 Mining stories, DRC copper items are still heavily weighted to primary operations like Kamoa-Kakula, so a JV explicitly targeting legacy tailings from districts active since the 1950s signals more attention to secondary copper supply and environmental liabilities in the country.
The presence of the US International Development Finance Corporation alongside Copper Intelligence and CoTec suggests this DRC tailings work could be structured to meet development-finance ESG and governance thresholds, which often becomes a de facto benchmark for other African copper waste-reprocessing projects.
