Zijin Gold International, a wholly owned unit of China’s Zijin Mining, is aiming to raise HK$24.98 billion ($3.21 billion) in a Hong Kong IPO, in what will be the largest in the city this year, according to its prospectus released on Friday, reports Reuters . Zijin Gold is selling 349 million shares at an offer price of HK$71.59 apiece, with trading to commence on the exchange on September 29, the prospectus showed. The deal will value Zijin Gold at $24.1 billion. Zijin Gold’s IPO is set to overtake Chinese automaker Chery’s offering this week that aims to raise up to $1.2 billion and become the largest in Hong Kong this year. Hong Kong’s capital market activity has been driven mainly by companies listed in mainland China making Hong Kong share sales.
