RioZim is weighing a listing on Zimbabwe’s Victoria Falls Stock Exchange, where trading is denominated in foreign currency, according to people familiar with the matter. The nickel, gold and diamonds producer is “seriously considering all options available to it under the legal framework of the country and will move in consonance with such opportunities,” Wilson Gwatiringa, a company spokesman said Thursday via text message. Any decision to list on the bourse would require shareholder approval, which has “neither been proposed or voted upon,” he said.
