Fronteer Completes Acquisition of Aurora

Fronteer Development Group Inc. announced today that it has acquired all of the remaining common shares of Aurora Energy Resources Inc. (”Aurora”) pursuant to a going private transaction involving the amalgamation (the “Amalgamation”) of Aurora and a direct wholly-owned subsidiary of Fronteer. The Amalgamation was approved and adopted at a special meeting of Aurora shareholders today.

Shareholders of Aurora (other than Fronteer) received one Class A redeemable preferred share of the amalgamated company for each Aurora common share held, and following the Amalgamation each outstanding Class A redeemable preferred share was automatically redeemed for 0.825 of a Fronteer common share (subject to adjustment for fractional shares), which is the same consideration per Aurora common share that shareholders received under Fronteer’s prior take-over bid for all of the common shares of Aurora.

Fronteer share certificates will be sent to all former Aurora shareholders who have delivered the certificate(s) representing the Aurora shares formerly held by them to Computershare Trust Company of Canada in Toronto, Ontario, together with a letter of transmittal. A copy of the letter of transmittal is available at www.sedar.com under Aurora’s profile. Any shareholder that has not delivered such share certificate(s) and a letter of transmittal must do so in order to receive the Fronteer share certificates the shareholder is entitled to. Shareholders whose share certificates are registered in the name of an investment advisor, stockbroker, bank, trust company or other nominee should immediately contact such nominee for assistance in surrendering their share certificates.

The common shares of Aurora will be delisted from and will no longer be traded on the Toronto Stock Exchange as of the close of market today.
