Trilogy Metals Reports High Grade Copper and Zinc from Drilling at its Arctic Deposit

VANCOUVER, Oct. 27, 2016 /PRNewswire/ – Trilogy Metals Inc. (TSX:TMQ) (NYSE:TMQ), formerly NovaCopper Inc., is pleased to announce drill results and provide a project update from its 2016 summer field program at the Arctic poly-metallic volcanogenic massive sulphide (VMS) deposit, part of the Upper Kobuk Mineral Projects (UKMP) located in the Ambler mining district of Northwest Alaska. All amounts are in United States dollars unless otherwise stated.

The majority of this year’s project budget of US$5.5 million was spent on a drilling program at the Arctic Project that included 3,058 meters of drilling for geotechnical, hydrological, waste rock characterization and metallurgical studies as well as further resource definition. In addition to the drilling program, a series of environmental studies were conducted over the UKMP. The LiDAR survey that was incomplete last year due to weather conditions was also completed during the summer. This site investigation work will form the basis for completing a future pre-feasibility study on the Arctic deposit.

Highlights from the Drill Program

Based on a cut-off grade of 0.7% copper, significant zones of high grade copper, gold, silver, lead and zinc mineralization were intersected – including:

• AR16-0155 intersected three mineralized intervals, including 36.36 meters of 2.27% copper, 0.27 g/t gold, 25.3 g/t silver, 0.36% lead, and 2.54% zinc, and 8.48 meters of 6.14% copper, 1.32 g/t Au, 96.6 g/t silver, 1.93% lead, and 8.27% zinc;

• AR16-0148 intersected four mineralized intervals, including 21.22 meters of 3.79% copper, 0.85 g/t gold, 69.1 g/t silver, 0.99% lead, and 5.78% zinc;

• AR16-0150 intersected five mineralized intervals, including 16.60 meters of 5.40% copper, 0.20 g/t gold, 46.0 g/t silver, 1.23 % lead, and 6.69 % zinc; and

• AR16-0153 intersected 12.59 meters of 2.49% copper, 0.86 g/t gold, 56.6 g/t silver, 2.17 % lead, and 9.64 % zinc.

“We are pleased to announce another highly successful and safe field season at our high grade Arctic deposit. We had Zero Loss Time Incidents, no environmental incidents and maintained a high percentage of local NANA shareholder hire. We continue to see exceptional high grades of copper, zinc and precious metals reported for all in-fill drill holes. The results demonstrate the continuity of multiple high grade zones of copper, zinc and precious metals,” stated Rick Van Nieuwenhuyse, President and Chief Executive Officer for Trilogy Metals. “By completing an array of studies, including geotechnical for pit-slope stability, hydrology, waste rock characterization, environmental and metallurgy, we continue to advance Arctic towards a pre-feasibility level of study which will demonstrate that Arctic is one of the highest grade, open pitable copper deposits in the world. By having exposure to copper, zinc and precious metals, the Company maintains its flexibility as we advance this project up the value chain. Meanwhile, the Alaska Industrial Development and Export Authority (AIDEA) continues to advance permitting of the Ambler Mining District Industrial Access Project (AMDIAP) – a road connecting the Ambler mining district to a year-round port at Port Mackenzie.”
