October 19, 2012

NEWS RELEASE Acadian Update Regarding Listing of its Shares Halifax, Nova Scotia - Acadian Mining Corporation ("Acadian" or the "Company") announces that the Toronto Stock Exchange (the "TSX") notified the Company that it has determined to delist the Company's common shares from the TSX at the close of market on November 29, 2012 for failure to meet the continued listing requirements of the TSX.

After careful consideration, Acadian concluded it was in the best interest of the Company and its shareholders to pursue a listing on the TSX Venture Exchange (the "TSXV") to ensure, subject to the TSXV approval, continued and seamless trading liquidity for the Company's shareholders. As a result, Acadian has filed an application with the TSXV under the streamlined listing procedure for listing as a Tier 2 issuer. Management is currently working on completing the necessary filings to obtain the TSXV conditional listing approval prior to the delisting of its common shares from the TSX.
The Company's common shares will continue to trade in the United States on the over the counter market under the symbol "ADAIF".
The Company will provide updates in the following weeks.
