Al Jazeera's Investigative Unit sends undercover reporters posing as representatives of a criminal syndicate looking to launder dirty money through gold. Over four episodes, hidden cameras catch dealers, bankers, and fixers in Zimbabwe and South Africa explaining, in their own words, how smuggled gold gets turned into clean cash: fake church ministries used as money-laundering fronts, sanctioned businessmen brokering deals, and gold bars moved across borders to dodge taxes and sanctions. The reporters are offered ways to launder tens of millions of dollars, and the people making the offers do not know they are being filmed. The series follows the money from artisanal mines through smuggling networks to the offshore accounts and shell companies that clean it, naming specific operators and showing the paperwork and recorded meetings that back up the claims. It is a straightforward undercover exposé: patient setup, hidden-camera confrontations, and a paper trail, aimed at showing how gold has become a preferred tool for sanctions evasion and organized financial crime in southern Africa.
