Welcome back to another edition of the daily Clue Challenge — where geopolitics, energy security, critical minerals, and hidden global stories come together.
Today’s challenge takes us deep into Central Africa, into one of the world’s most strategically important mining regions.
This location is at the center of the electric vehicle revolution. It helps power smartphones, laptops, military systems, and lithium-ion batteries used across the globe.
But behind the clean energy transition lies a darker story involving pollution, displacement, toxic gas emissions, and growing concerns over global supply chains. Can you identify this controversial mega-mine?

The Clues
- Located in the Democratic Republic of the Congo (DRC), which dominates global cobalt production.
- Operated through a subsidiary connected to CMOC Group Limited.
- Became globally important due to the rapid rise in demand for EV lithium-ion batteries.
- In 2023, a massive new copper-cobalt processing facility known as the “30k plant” began operations here.
- The complex handles around 30,000 tons of ore daily, dramatically increasing capacity.
- Nearby communities report severe respiratory illnesses, nosebleeds, and pregnancy complications.
- Independent investigations found sulphur dioxide (SO₂) concentrations exceeding international safety limits.
- Air quality issues are linked to ore processing and alleged toxic gas releases.
- More than 12,000 people were reportedly displaced due to site expansion.
- In 2024, it became the first Chinese-owned mine in Africa to receive the Copper Mark ESG certification.
- Extracted cobalt is primarily exported to China and Europe for battery manufacturing.
- Supply chains link this mine to major automakers like BMW, Mercedes-Benz, Volkswagen, and Stellantis.
- The mine sits in one of the world’s richest copper-cobalt belts, central to the clean energy transition.
- Critics argue the “green energy” push depends on minerals extracted under controversial social conditions.
