The Federal Court of Australia has made orders approving the scheme of arrangement between Altona Mining Ltd. and its shareholders under which Copper Mountain Mining Corp. will acquire all of the shares in Altona. Copper Mountain anticipates that Altona will lodge a copy of the Court's orders approving the scheme with the Australian Securities and Investment Commission on April 4, 2018, at which time the scheme will become effective.

The company is also pleased to announce it has received approval, subject to the usual conditions, from the Australian Securities Exchange for the admission of Copper Mountain to the official list and to the official quotation of Copper Mountain's CHESS Depository Instruments (CDIs). It is anticipated that trading in Altona's shares on the ASX will be suspended from close of trading on April 4, 2018, and that trading in Copper Mountain CDIs (which have been assigned a stock code of C6C) is expected to commence on a deferred settlement basis on April 5, 2018.

It is anticipated that the scheme will be implemented on April 18, 2018, at which time Copper Mountain CDIs will commence trading on the ASX.
