Tax authorities in the Democratic Republic of Congo sealed offices at Glencore-operated Kamoto on July 9 as a transfer-pricing dispute intensified, with claims estimated at $3 billion to $6 billion. The mine is a key source of cobalt, and Kamoto and Mutanda together produced 247,800 metric tons of copper and 33,500 metric tons of cobalt in 2025. It remains unclear how long the measure will last, raising the risk of short-term disruption. The move threatens Orion Critical Minerals’ proposed $9 billion investment, according to Bankable.
