VANCOUVER, BRITISH COLUMBIA -- (Marketwire - Oct. 27, 2011) - Hathor Exploration Limited (TSX: HAT) ("Hathor") is pleased to announce that, further to the joint press release of October 19, 2011, it has now received a formal all cash take-over bid offer (the "Offer") from an indirect wholly owned subsidiary (the "Offeror") of Rio Tinto, at a price of $4.15 per Common Share, for all of the outstanding common shares ("Common Shares") of Hathor, together with the associated rights (the "SRP Rights") issued and outstanding under Hathor's shareholder rights plan, other than any Common Shares owned directly or indirectly by the Offeror and its affiliates, and including any Common Shares that may become issued and outstanding after the date of the Offer but prior to the Expiry Time (as defined below) upon the exercise, exchange or conversion of: (i) options under Hathor's stock option plan, (ii) issued and outstanding warrants of Hathor, or (iii) other securities of Hathor that are exercisable or exchangeable for or convertible into Common Shares (other than the SRP Rights).

As previously announced, a Support Agreement dated October 18, 2011 entered into by the Offeror, an affiliate of the Offeror and Hathor includes a non-solicitation covenant, a right by the Offeror to match any unsolicited superior proposal and payment by Hathor to the Offeror of a break fee of $20 million in certain circumstances.

Full details of the Offer are set forth in the offer to purchase and related take-over bid circular dated October 25, 2011 (the "Offer to Purchase and Circular") and the letter of transmittal and the notice of guaranteed delivery accompanying the Offer to Purchase and Circular (collectively, the "Offer Documents"), copies of which have been filed with the securities regulatory authorities in Canada and will be mailed to Hathor's securityholders shortly. The Offer will expire at 5:00 p.m. (Toronto time) on November 30, 2011 (the "Expiry Time"), unless otherwise extended or withdrawn, and is subject to a number of customary conditions, including (i) there being deposited under the Offer and not withdrawn at the Expiry Time such number of Common Shares that represent at least 66 2/3% of the Common Shares calculated on a fully-diluted basis, and (ii) the receipt of all necessary regulatory approvals.

The Board of Directors of Hathor ("Hathor Board"), after consultation with its financial and legal advisors and on receipt of a recommendation of its Special Committee, has unanimously determined that the Offer is in the best interests of Hathor and holders of Common Shares (the "Shareholders") (other than the Offeror and its affiliates) and, accordingly the Hathor Board has agreed to unanimously recommend that Shareholders ACCEPT the Offer and tender their Common Shares to the Offer. A more detailed discussion of the reasons for accepting the Offer and the written opinions provided by Canaccord Genuity Corp. and Scotia Capital Inc. are contained in the Directors' Circular that has been filed with the securities regulatory authorities in Canada and will be mailed to Hathor securityholders shortly.

Roughrider Project Update

Further to Hathor's September 13, 2011 press release announcing the receipt from SRK Consulting (Canada) Inc. ("SRK") of summary results of its preliminary economic assessment on the Roughrider uranium deposit (the "PEA"), Hathor announces that it has filed a National Instrument 43-101 compliant technical report prepared by SRK on SEDAR supporting the disclosure of the PEA in the September 13th press release. The technical report is consistent with the summary results announced in the September 13th press release, except for the payback period, which SRK has determined was miscalculated in its summary results and has increased in all three cases reported, (from 1.6 years to 2.2 years in Case A; from 1.2 to 1.8 years in Case B; from 0.8 to 1.4 years in Case C), a change which does not affect other aspects of the PEA and which SRK and Hathor deem not material to the results of the study.
