Hathor Board Recommends Rio Tinto's Increased All-Cash Offer of C$4.70 Per Share for Hathor Exploration

VANCOUVER, BRITISH COLUMBIA -- (Marketwire - Nov. 17, 2011) - Hathor Exploration Limited (TSX: HAT) ("Hathor") announces that Rio Tinto plc. (LSE:RIO)(ASX:RIO)(NYSE: RIO), through an indirect wholly-owned Canadian subsidiary ("Rio Tinto"), has increased its all-cash offer to acquire all of the outstanding common shares of Hathor to $4.70 per share (the "Increased Rio Offer"). All other terms of the offer will remain the same as those described in the Rio Tinto offer and the takeover bid circular dated October 25, 2011. Rio Tinto's increased offer values Hathor at approximately C$654 million on a fully-diluted basis and represents a premium to Cameco Corporation's unsolicited revised offer of C$4.50 per common share made on November 14, 2011 (the "Cameco Offer").

Hathor's board of directors, after receiving the recommendation of its special committee and the oral opinion of its financial advisor as to the fairness, from a financial standpoint, of the Increased Rio Offer, has unanimously determined that the Increased Rio Offer is in the best interests of Hathor's shareholders and reaffirms its support of Rio Tinto's increased offer and unanimously recommends that Hathor shareholders accept and tender their common shares to the Increased Rio Offer and reject the Cameco Offer.

The support agreement between the Rio Tinto and Hathor has been amended by the parties to reflect Rio Tinto's increased offer and remains in effect. The lock-up agreements with Hathor directors and senior officers also remain in effect.

The Increased Rio Offer remains open for acceptance until 5:00pm (Toronto time) on November 30, 2011, unless extended or withdrawn in accordance with its terms. Full details of the Increased Rio Offer will be included in a notice of variation that will be mailed by Rio Tinto to Hathor securityholders shortly and filed on SEDAR. The Increased Rio Offer is subject to customary conditions, as described in the original offer and takeover bid circular dated October 25, 2011 and previously delivered to Hathor securityholders.

If shareholders wish to obtain any information about existing offers, please contact Hathor's information agent, Phoenix Advisory Partners, at 1-800-243-1162.
