In Puinawai National Park in Colombia, law enforcement officials are increasingly cracking down on the link between coltan mining and Drug Trafficking. According to documents filed in the US Federal Court, members of the Cifuentes Villa family run a collection of cobalt mines that have been described by prosecutors as a Money Laundering operation, used to support a criminal narcotics enterprise. Mines operated by the Cifuentes Villa family have been blacklisted by the US Treasury, presenting a Sanctions Evasion risk, and Colombian authorities have pulled their license to mine cobalt in certain hotspot areas.
