Aurora Energy Resources Inc. ("Aurora" or the "Company") (AXU:TSX) announced today that its Board of Directors has issued a Notice of Change to Directors' Circular in respect of the offer (the "Fronteer Offer") by Fronteer Development Group Inc. ("Fronteer") to acquire all of the common shares of Aurora that it does not already own on the basis of 0.825 of a Fronteer common share for each Aurora common share.  The Notice of Change to Directors' Circular will be mailed to shareholders and will be available on www.sedar.com.

On February 5, 2009, the Board decided they would defer making a recommendation to Shareholders with respect to the Fronteer Offer.  At that time, the Special Committee was engaging in discussions with third parties to solicit other offers for Aurora or its assets or other transactions involving Aurora.  The Board did not believe that it was in a position at that time to make a recommendation with respect to the Fronteer Offer until these discussions had concluded.  Accordingly, a Directors' Circular dated February 6, 2009 was mailed to shareholders and filed on www.sedar.com that summarized the situation at that time but set out no recommendation from the Board.

Discussions between third parties and the Special Committee have terminated without an alternative to the Fronteer Offer emerging.  The Board of Directors is now recommending (with all attending members of the Board voting in favour) that Aurora shareholders accept the Fronteer Offer and deposit their Aurora common shares to the Fronteer Offer.  Aurora shareholders should read carefully the reasons for this recommendation contained in the Notice of Change, together with the other information contained in the Notice of Change and the Directors' Circular, before deciding whether or not they will deposit their common shares to the Fronteer Offer.

The Special Committee of the Aurora Board of Directors has retained National Bank Financial Inc. as its financial advisor to advise it with respect to the Fronteer Offer.  National Bank Financial Inc. has delivered to the Special Committee and Board of Directors its opinion that, based upon and subject to the considerations, assumptions and limitations described therein, as of February 20, 2009 the consideration offered pursuant to the Fronteer Offer is fair, from a financial point of view, to Aurora shareholders other than Fronteer.

The Fronteer Offer will be open for acceptance until 8:00 p.m. (Toronto time) on March 2, 2009, unless extended or withdrawn.  Reference is made to Fronteer's take-over bid circular dated January 23, 2009, which accompanies the Fronteer Offer, for details of additional terms and conditions of the Fronteer Offer.
