COPPER MOUNTAIN ANNOUNCES Q1 2018 PRODUCTION RESULTS

Copper Mountain Mining Corp. has released its production results for the first quarter of 2018 from the Copper Mountain mine, located in Southern British Columbia.

First quarter 2018 production highlights:

• Production on track: Production totalled 23.2 million pounds of copper equivalent during the quarter, which included:
  • 19.9 million pounds of copper (a 10-per-cent increase over Q1 2017);
  • 6,070 ounces of gold;
  • 77,900 ounces of silver.
• Gold and silver: Gold and silver production continues to provide a favourable contribution to the operation.
• Mill throughput: The average milling rate for Q1 2018 was 38,800 tonnes per day for the quarter. Total tonnes milled during the period were 3.5 million tonnes at an average head grade of 0.328 per cent copper.
• Mining production: Open-pit mining averaged 184,300 tonnes of material per day during the first quarter, within 3 per cent of the company's 190,000 tonnes per day guidance, with the slight decrease related to the abnormally high snowfall.

Mining activities continued from the Pit 2, Saddle and Oriole areas during the quarter. A total of 16.6 million tonnes of material was mined, including 6.5 million tonnes of ore and 10.1 million tonnes of waste, resulting in a strip ratio of 1.54 to one.

Jim O'Rourke, president and chief executive officer of Copper Mountain Mining, said: "The operation performed well during the quarter despite the abnormally high snowfall causing some challenges in the pit and a minor disruption in power supply. These challenges were handled well by the crew, which has kept us on track to meet our 2018 production guidance of 80 million pounds of copper."

Copper Mountain will hold a conference call on Friday, April 27, 2018, at 7:30 a.m. Pacific Standard Time for management to discuss the Q1 2018 financial and operating results. Results will be released before the market opens on Friday, April 27, 2018.
