One of Brazil’s biggest gold refiners, which processes gold suspected of being mined illegally in the Amazon rainforest, has been stripped of an important industry seal of approval that global manufacturers from Apple to Tesla rely on to root out abuses in their supply chains.
An investigation by The Associated Press in January revealed how Sao Paulo-based Marsam shared ownership links and processes gold on behalf of an intermediary accused by Brazilian prosecutors of buying tarnished gold from Indigenous territories and other protected areas.
