Mining giant Rio Tinto has, through an indirect wholly-owned subsidiary, acquired the remaining 5.87%, or 7.9m Hathor shares not already owned by Rio. The firm now anticipates that the Hathor shares will be delisted from the Toronto Stock Exchange by the end of today, Thursday January 12th. It was announced on Monday that Rio had taken up 93.76% of the outstanding common shares of the Canadian uranium firm, following a determind takeover process. During the latter part of 2011, Rio extended its deadline for acceptance of its $654m bid several times.NR
