COPPER MOUNTAIN'S ACQUISITION OF ALTONA MINING RECEIVES SHAREHOLDER APPROVAL

Copper Mountain Mining Corp. and Altona Mining Ltd. shareholders have respectively voted in favour of the share issuance resolution and the scheme of arrangement, providing for the acquisition of Altona by Copper Mountain, at their special meetings of shareholders.

"We are pleased to have received the support of shareholders from both companies. Altona's assets include $30-million in cash, a permitted development project in Queensland, Australia, and a large mineral land tenure position in the highly prospective area. The Altona team has done an outstanding job in pulling together an exceptional mineral land package in a prolific mineral belt that we believe will provide long-term value to all shareholders," said Jim O'Rourke, president and chief executive officer of Copper Mountain.

Altona will now seek orders from the Federal Court of Australia for approval of the scheme at a hearing scheduled for early April, 2018. The transaction is expected to close by mid-April, 2018, subject to applicable regulatory approvals, and the satisfaction of other customary conditions.

About Altona Mining Ltd.

Altona's principal asset is the Cloncurry copper project in Queensland, Australia, found within a dominant 3,970-square-kilometre land package in the highly prospective Mt. Isa inlier. It is envisaged that an open pit copper-gold mine and a seven-million-tonne-per-annum concentrator will be developed. The development is permitted with proposed annual production of 39,000 tonnes of copper and 17,200 ounces of gold for a minimum of 14 years.

About Copper Mountain Mining Corp.

Copper Mountain's flagship asset is the Copper Mountain mine located in Southern British Columbia near the town of Princeton. The company has a strategic alliance with Mitsubishi Materials Corp., which owns 25 per cent of the mine. The Copper Mountain mine has a large resource of copper that remains open laterally and at depth. This significant exploration potential is being explored over the next few years in order to fully appreciate the property's full development potential.
