COPPER MOUNTAIN COMPLETES PHASE 2 DRILL PROGRAM AT NEW INGERBELLE WITH CONTINUED POSITIVE RESULTS

Copper Mountain Mining Corp. has completed phase 2 of its three-phase drilling program at the New Ingerbelle property, and results continue to be positive. New Ingerbelle is located adjacent to the present operations of the Copper Mountain mine.

Highlights from the remaining 14 drill holes of phase 2 include:

• Hole 18IG-24 returning 188 metres of 0.55 per cent copper equivalent (CuEq) (0.38 per cent copper, 0.45 gram per tonne silver and 0.25 g/t gold), which includes 114 metres of 0.71 per cent CuEq (0.49 per cent Cu, 0.51 g/t Ag, 0.32 Au g/t);
• Hole 18IG-26 returning 135 metres of 0.71 per cent CuEq (0.49 per cent Cu, 0.97 g/t Ag, 0.32 g/t Au);
• Hole 18IG-18 returning 339 metres of 0.37 per cent CuEq (0.27 per cent Cu, 0.53 g/t Ag, 0.14 g/t Au);
• Hole 18IG-27 returning 96 metres of 0.55 per cent CuEq (0.39 per cent Cu, 0.69 g/t Ag, 0.23 g/t Au);
• Hole 18IG-28 returning 54 metres of 0.58 per cent CuEq (0.42 per cent Cu, 0.80 g/t Ag, 0.23 g/t Au) and 90 metres of 0.62 per cent CuEq (0.46 per cent Cu, 0.57 g/t Ag, 0.23 g/t Au).

Gil Clausen, Copper Mountain's president and chief executive officer, stated: "These drill results continue to demonstrate that New Ingerbelle has the potential to be of considerable size and significance to the company. We have extended mineralization below prior resource limits, expanded it laterally and filled in the resource as planned. With the phase 2 drilling program complete, we are now working on incorporating the results into an updated mineral resource for New Ingerbelle, which we expect to announce shortly. We believe New Ingerbelle will continue to increase in significance as a development project for the company and will fit perfectly in our organic development pipeline of growth projects."

Copper Mountain initiated a three-phase drilling program at the New Ingerbelle mine last year with phase 1, which was successful in validating and confirming historical data. Phase 2, which consisted of 29 drill holes totalling approximately 10,000 metres, was designed to expand the New Ingerbelle resource area and convert inferred mineral resources to the measured and indicated status. Having now completed the second phase, work is currently under way to update the resource. The updated resource estimate is planned to be announced before the end of the third quarter of 2018. Significant intercepts from the remaining 14 holes that have not yet been announced from the phase 2 drill program, are summarized in the attached table.

About Copper Mountain Mining Corporation

Copper Mountain's flagship asset is the 75-per-cent-owned Copper Mountain mine located in Southern British Columbia near the town of Princeton. The Copper Mountain mine produces about 90 million pounds of copper equivalent per year with a large resource that remains open laterally and at depth. Copper Mountain also has the permitted, development-stage Eva copper project in Queensland, Australia, and an extensive 379,000-hectare highly prospective land package in the Mount Isa area.

Quality assurance/quality control

Diamond drilling, which runs 24 hours a day, seven days a week, uses NQ2-diameter rods and bits, and drill core is placed in wooden boxes that are delivered to the core logging area at the end of every shift. Drill hole collars are surveyed with differential GPS (global positioning system) and downhole surveys using a Reflex instrument are taken approximately every 30 metres to 80 metres, depending on ground conditions and hole length. The core is logged, and sample tags are stapled into the boxes where samples are to be taken and the core is photographed. Core recovery is always at, or near, 100 per cent, except for fault zones. All assay samples are three metres in length. Core is split with a diamond saw, and samples are transported to the mine's analytical laboratory by members of the exploration team. Samples are sorted, weighed, dried and crushed prior to pulverizing to 75 per cent passing minus 200 mesh. Copper and silver are analyzed by XRF (X-ray fluorescence) and samples with over 0.4 per cent copper are reanalyzed by atomic absorption. Sample pulps for all samples over 0.1 per cent copper are delivered to a commercial lab for gold analysis by either fire assay or aqua regia digestion followed by AA analysis. Additionally, every 10th sample is analyzed by ICP-AES for a 35-element suite, which includes copper and silver, providing checks on the mine-site laboratory, in addition to routine insertion of standards and blanks. All pulps and coarse reject material are retained.

We seek Safe Harbor.
