MOSCOW : Russian miners and Chinese investors are among the parties interested in buying gold and silver producer Polymetal International's Russian assets, CEO Vitaly Nesis told the Financial Times. Polymetal had considered spinning off its Russian business after re-domiciling to Kazakhstan from Jersey, but U.S. sanctions imposed on its Russian assets complicated that process, forcing the group to seek a sale. Nesis last week said on an investor call that a sale was now the only reasonable option and that the company intended to sell within six to nine months.
