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 Q1 2018.

Highlights from the Drill Program

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.

"These results from large diameter drill holes continue to demonstrate that Arctic is an exceptional copper-zinc rich deposit. Further engineering and environmental work completed this summer will support completion of the Arctic Pre-feasibility Study by the end of Q1, 2018. We expect this study will demonstrate that Arctic is one of the highest grade, open pitable copper deposits in the world. And it is located in a mining friendly jurisdiction in the United States where both our shareholders and stakeholders will be able to reap the benefits of our efforts. Meanwhile, the Alaska Industrial and Export Authority ("AIDEA") continues to advance permitting of the Ambler Mining District Industrial Access Project with the scoping process set to be finalized by the end of January", stated Rick Van Nieuwenhuyse, President and CEO of Trilogy Metals.  

Trilogy Metals completed five PQ diamond drill holes for a total of 785.2 meters of core (see Figure 1). 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 is pleased to announce 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 are reported in Table 1. These drill results, along with ongoing engineering and environmental studies described below, will be used to support the PFS on the Arctic deposit.

Pre-Feasibility Study Update

Trilogy Metals completed 11 sonic drill holes (273.8 meters), 26 test pits, and 2 pump tests during the 2017 field season.  This program was developed to collect geotechnical, hydrological, geothermal (permafrost), and hydrogeological information for the various tailings management facilities and waste rock dump areas for the Arctic project.  Four of the sonic drill holes were instrumented with thermistors, piezometers and data loggers that will allow for long term baseline monitoring information to be gathered that will be required for a future permitting document. 

On-going baseline environmental data collection included maintenance of three hydrologic gauging stations and one meteorological station. Surface water quality samples were taken from several surface water locations and analyzed for a full suite of parameters including total and dissolved metals.  An aquatics survey of rivers and creeks over the UKMP included identification of fish species present and tissues metals testing.  An avian survey over the UKMP was conducted in May to identify bird nest locations, with a follow-up survey in July to measure fledging success.

The Company continues to advance the acid-base-accounting static and kinetic test work at Arctic. Six on-site barrel samples were successfully collected during all seasons of 2017 to support the kinetics program.  Maintenance and monitoring of all kinetic tests continues into 2018.

Trilogy Metals is pleased to announce that the Pre-Feasibility Study is on schedule and anticipated to be completed by the end of the first quarter in 2018.

QAQC Program

The drill program, sampling protocol, and data verification were managed by qualified persons employed by Trilogy Metals. The diamond drill holes were drilled at PQ diameter drill core. Samples were collected using a 0.17-meter minimum length, 5-meter maximum length and 2.4-meter average sample length (1.7m through the mineralized zones). Drill core recovery averaged 96% overall. Three quality control samples (one blank, one standard and one duplicate) were inserted into each batch of 20 samples. The drill core was sawn, with a quarter sent to ALS Minerals in Fairbanks for sample preparation and the sample pulps forwarded to ALS's North Vancouver facility for analysis. ALS Minerals in North Vancouver, B.C., Canada, is an independent facility certified as ISO 9001:2008 and accredited to ISO / IEC 17025:2005 from the Standards Council of Canada.  Results of the control samples were reviewed by a QP and were all within acceptable limits. Trilogy Metals will submit 5% of the assay intervals from prospective lithologies to an independent check assay lab.
