VANCOUVER, Nov. 9, 2017/PRNewswire/ - Trilogy Metals Inc. (TSX, NYSE-MKT:TMQ) ("Trilogy Metals" or "the Company") has filed a National Instrument 43-101 technical report with the Canadian securities regulators relating to the Arctic Project which supports the resource estimate previously announced on April 25, 2017 which is of sufficient quality to support the Arctic pre-feasibility study ("PFS").  The technical report is entitled NI 43-101 Technical Report on the Arctic Project, Northwest Alaska, USA and prepared by Bruce Davis, Robert Sim and Jeff Austin, all of whom are "Qualified Persons" under NI 43-101 (the "Technical Report").  The Arctic Project is estimated to contain at a base case of 0.5% copper equivalent cut-off grade, an in-pit indicated resource of approximately 36 million tonnes of copper grading 3.07% (see Table 1) that are expected to form the basis for the PFS and the Company's first reserves in the Ambler Mining District. The PFS is on target to be released in the first quarter of 2018.

Rick Van Nieuwenhuyse, President and CEO of Trilogy Metals, commented, "We are excited in the progress made to date towards finalizing the pre-feasibility study for our high-grade Arctic Project in Q1 2018.  Arctic is pretty special – we predict it will be one of the highest grade open pit copper projects in the world.  Arctic is also located in the geographic center of a 100 Km long belt containing over two dozen known grade polymetallic deposits and occurrences.  It is not hard to envision a central milling concept with the other deposits potentially feeding the mill beyond the mine life at Arctic.  With the Ambler Mining District Industrial Access Project ("AMDIAP") now in the formal permitting process and public scoping meetings taking place, it is exciting to see the Ambler Access Road finally taking shape."

Table 1. Estimate of Mineral Resources for the Arctic Deposit

• Base Case cut-off grade of 0.5% CuEq.
• Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. There is no certainty that all or any part of the Mineral Resources will be converted into Mineral Reserves. See "Cautionary Note to United States Investors."
• Resources stated as contained within a pit shell developed using metal prices of US$3.00/lb copper, US$0.90/lb lead, US$1.00/lb zinc, US$1300/oz gold, US$18/oz silver, mining costsof US$3.00/tonne, milling and G&A costs of US$35/tonne, metallurgical recoveries of 92% for copper, 77% for lead, 88% for zinc, 63% for gold, 56% for silver and an average pit slope of 43 degrees.
• Inferred resources have a great amount of uncertainty as to whether they can be mined legally or economically. It is expected that a majority of the inferred resources will be converted to indicated mineral resources with continued exploration.

The sensitivity of mineral resources, contained within the resource limiting pit shell, is demonstrated by listing resources at a series of cut-off thresholds as shown in Table 2.

Table 2. Sensitivity of Mineral Resources to Cut-off Grade

• Base Case cut-off grade of 0.5% CuEq is highlighted in table.

Mineral resource estimates are made from a 3D block model based on geostatistical applications using commercial mine planning software (MineSight® v11.60-2). The block model has a nominal block size measuring 10 x 10 x 5 m and utilizes data derived from 152 drill holes in the vicinity of the Arctic deposit. The resource estimate was generated using drill hole sample assay results and the interpretation of a geological model which relates to the spatial distribution of copper, lead, zinc, gold and silver.  Interpolation characteristics were defined based on the geology, drill hole spacing, and geostatistical analysis of the data. The effects of potentially anomalous high-grade sample data, composited to two metre intervals, are controlled by limiting the distance of influence during block grade interpolation. The grade models have been validated using a combination of visual and statistical methods. The resources were classified according to their proximity to the sample data locations and are reported, as required by NI 43-101 (as defined herein), according to the 2014 CIM Definition Standards for Mineral Resources and Mineral Reserves. Model blocks estimated by three or more drill holes spaced at a maximum distance of 100 metres are included in the Indicated category. Inferred blocks are within a maximum distance of 150 metres from a drill hole. The estimate of Indicated and Inferred mineral resources is within a limiting pit shell derived using projected technical and economic parameters.

About Trilogy Metals

Trilogy Metals Inc. is a metals exploration company focused on exploring and developing the Ambler mining district located in northwestern Alaska. It is one of the richest and most-prospective known copper-dominant districts located in one of the safest geopolitical jurisdictions in the world. It hosts world-class polymetallic VMS deposits that contain copper, zinc, lead, gold and silver, and carbonate replacement deposits which have been found to host high grade copper mineralization. Exploration efforts have been focused on two deposits in the Ambler mining district - the Arctic VMS deposit and the Bornite carbonate replacement deposit. Both deposits are located within the Company's land package that spans approximately 143,000 hectares. The Company has an agreement with NANA Regional Corporation, Inc., a Regional Alaska Native Corporation that provides a framework for the exploration and potential development of the Ambler mining district in cooperation with local communities. Our vision is to develop the Ambler mining district into a premier North American copper producer.
