In April 2014 the Guinean government cancelled the company's mining rights in Simandou. BSGR has denied any wrongdoing, and in May 2014 sought arbitration over the government of Guinea's decision to expropriate its mining rights. In February 2019, BSGR and Guinean President Alpha Condé agreed to drop all allegations of wrongdoing as well as the pending arbitration case. Under the agreement, BSGR would relinquish rights to Simandou while being allowed to maintain an interest in the smaller Zogota deposit that would be developed by Niron Metals head Mick Davis.
