One of Brazil’s biggest gold refiners delisted amid an Amazon mining probe

MIAMI (AP) — 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.

A former partner at Marsam, Dirceu Frederico Sobrinho, has been at the center of recent gold rush in the Amazon, purchasing through a separate company he controls more than 2 billion reais ($388 million) worth of gold last year from wildcat miners at 252 sites. Last year, federal prosecutors filed a civil suit against the company, F.D’Gold , and two other companies that purchase gold, seeking 10 billion reais in social and environmental damages.

With that lawsuit still going on, Marsam this month was quietly removed by the Responsible Minerals Initiative from a public list of smelters and refiners deemed to follow best sourcing practices. The assessment program run by a Virginia-based coalition of manufacturers emerged with the passage a decade ago of legislation in the U.S. requiring companies to disclose their use of conflict minerals fueling civil war in the Democratic Republic of Congo.

André Nunes, an external consultant for Marsam, said it would appeal the initiative’s decision. He said Marsam conducted its own evaluation of F.D’Gold and found nothing amiss.

He also cautioned that the accusations of illegal mining against Marsam’s client have yet to be proven, citing a procedural decision last month by a judge who blasted prosecutors for not providing sufficient evidence to back their request that company’s activities be suspended pending the outcome of the investigation.

“In Marsam’s understanding, we were diligent and did what was within our reach,” Nunes said. “We didn’t see a reason to end our relationship with F.D’Gold and the judiciary corroborated that decision.”

The Responsible Minerals Initiative wouldn’t disclose its findings, citing confidentiality agreements to encourage companies to participate in its evaluation process. But according to its standards, refiners can be removed from its “conformant” list for a variety of reasons, ranging from not performing enhanced due diligence when red flags are raised — something Marsam’s internal policies also require — to overlooking evidence that actors in its supply chain falsified mandatory declaration of origin forms, a rampant problem in the Amazon’s prospecting frontier.

More than 300 publicly traded companies list Marsam as a supplier in responsible mining disclosures that they are required to file with the U.S. Securities and Exchange Commission. Such sourcing decisions are guided by independent auditors who evaluate refiners to make sure they aren’t contributing to illegal armed groups, human rights violations and financial wrongdoing. Currently, 98 refiners are considered to be aligned with the initiative’s standards — the same status Marsam enjoyed from 2017 until its recent delisting.

Additionally, Marsam provided the gold that was used to make the medals hanging on the necks of athletes in the 2016 Olympic Games in Rio de Janeiro — medals touted as a victory for the environment because they were partly made from recycled materials and free of mercury.

But critics said much of Marsam’s bona fides were undeserved. They accuse the company of “greenwashing” — promoting itself as more sustainable than it really is — by not delving deep into the origin of the ore it processes on behalf of F.D’Gold.

Marsam is now co-run by the daughter of Dirceu, as he is widely known in Brazil.

“In Brazil, as in so many gold-producing countries, illegality enters into the supply chain very early on, so it’s essential to get better visibility on what happens upstream,” said David Soud, head of research at I.R. Consilium, who has researched illegal gold flows in South America. “Refiners are often culpable for failures in due diligence and need to be held to strict standards so that questionably sourced gold doesn’t get laundered into the legitimate supply chain.”

Illegal airstrips, toxic mercury ponds and forest-wrecking heavy machinery have proliferated throughout the Amazon as prospecting for gold on Indigenous lands and other protected areas has exploded in recent years. Weak government oversight enabled by President Jair Bolsonaro, the proud son of a prospector whose administration has facilitated mining in the Amazon, has…
