Trilogy Metals Inc. announced additional in-fill drill results and provides a project update from its 2017 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 2017 Arctic field program included 785.2 meters of diamond drilling to collect representative sample material to conduct bulk ore sorting studies for the Arctic deposit. An additional 273.8 meters of sonic drilling was completed to collect geotechnical, hydrological, geothermal, and hydrogeological information for the tailings management facilities and waste rock dump for the project in support of the upcoming Pre-Feasibility Study ("PFS"). The PFS results are anticipated to be released in first quarter of 2018. Based on a cut-off grade of 0.5% CuEq, significant zones of high grade copper, zinc, lead, gold, and silver mineralization were intersected – including: AR17-0159 intersected four mineralized intervals, including 31.11 meters of 1.58% copper, 2.84% zinc, 0.69% lead, 0.38 g/t gold, and 30.79 g/t silver, and 15.25 meters of 2.91% copper, 4.34% zinc, 0.96% lead, 0.66 g/t gold, and 44.27 g/t silver;AR17-0160 intersected four mineralized intervals, including 25.95 meters of 2.43% copper, 1.19% zinc, 0.16% lead, 0.59 g/t gold, and 46.31 g/t silver, and 17.23 meters of 4.42% copper, 5.32% zinc, 1.37% lead, 0.13 g/t gold, and 43.92 g/t silver;AR17-0161 intersected two mineralized intervals, including 17.60 meters of 2.69% copper, 5.50% zinc, 1.14% lead, 0.66 g/t gold, and 54.47 g/t silver, and 4.40 meters of 3.01% copper, 3.80% zinc, 0.95% lead, 0.54 g/t gold, and 50.90 g/t silver; AR17-0162 intersected one mineralized interval, 6.75 meters of 2.35% copper, 6.00% zinc, 1.57% lead, 0.71 g/t gold, and 43.27 g/t silver; and AR17-0163 intersected one mineralized interval, 6.48 meters of 2.95% copper, 6.33% zinc, 1.40% lead, 0.84 g/t gold, and 44.23 g/t silver. The company completed five PQ diamond drill holes for a total of 785.2 meters of core. This drill program was designed to collect 2 tons of representative mill-feed material for bulk ore sorting test work at the Steinert facility in Kentucky, USA, an independent facility. The core was quartered for geochemical analysis, and the remaining core shipped to ALS Minerals, in North Vancouver, B.C., Canada, an independent laboratory for coarse crushing and chemical analysis.  The core will be sent to the Steinert facility in early 2018 for subsequent bulk ore sorting testing.  The ore sorting studies will be carried out after the PFS is released and if determined to be advantageous to overall project, will be incorporated in subsequent studies. The company announced that all five holes encountered mineralized intervals consistent with previous drilling conducted within the resource area on the property. Significant mineralized intervals of high-grade mineralization at a cutoff of 0.5% CuEq. These drill results, along with ongoing engineering and environmental studies described below, will be used to support the PFS on the Arctic deposit.
