“Mr. Steinmetz is robustly defending this claim, which is factually and legally without merit and which was brought outside the time limit for claims of this kind,” a spokesperson at Asserson, the law firm representing Steinmetz, said.

The trial which began Wednesday represents the latest chapter in a 12-year-old saga about control of one of the planet’s richest mineral deposits. Steinmetz, 65, acquired the rights to the Simandou iron-ore project in 2008, before the Guinean government took back the rights amid a corruption probe into how the Israeli businessman secured the resource. That probe in turn triggered investigations in the U.S. and Switzerland into Steinmetz, BSGR and other companies he controlled.

“If any of the defendants was genuinely honest they would recognize that BSGR was engaged in corrupt practices,” Vale’s lawyer, Sonia Tolaney, said in written documents prepared for the hearing.

Vale is seeking damages of up to $1.2 billion collectively from Steinmetz and his associates. The Brazilian miner sought and won in 2019 $2 billion in compensation from a London arbitration court, but that too has become the subject of a legal dispute as BSGR seeks to overturn it.

Steinmetz has faced further setbacks recently. In December 2020, he was convicted by a Romanian court in absentia over his role in a property bribery scheme. A month later, a Geneva judge convicted Steinmetz of bribery over the Simandou rights and sentenced him to five years in prison.

A quirk of Swiss law allowed Steinmetz within hours of his sentencing to return to Israel, from where he plans to appeal both the Swiss and Romanian convictions.

Two companies associated with Steinmetz, Balda Foundation and Nysco Management Corp., are also named in the suit underpinning the trial, set to last around eleven weeks.

Steinmetz is scheduled to appear in court to give evidence later in the trial. But Vale’s lawyers said there’s been indication he will not attend to give oral evidence, according to its written documents.
