The government of Guinea says it plans to revoke the mining rights to one of the largest untapped iron ore deposits in the world, following a watchdog's recommendation.
A committee reviewing mining deals in the west African country has said it has evidence the exploitation rights were obtained through corrupt practices and recommended they be cancelled.
The deal is also under US investigation.
Government spokesman Damantang Camara announced late on Friday that Guinea would follow the committee's recommendation.
The rights are held by a joint-venture owned by Israeli billionaire Beny Steinmetz's BSG Resources and Brazilian mining firm, Vale.
But the report focused its allegations on BSG Resources.
BSG Resources has said it will fight the allegations.
Vale has said it does not believe it has been accused of wrongdoing.
