Trilogy Metals Reports Additional Drilling Results from the Bornite Project
November 19, 2018 - Vancouver, British Columbia – Trilogy Metals Inc. (TSX/NYSE
American: TMQ) ("Trilogy Metals” or the “Company”) is pleased to announce the second set
of copper and cobalt assay results from the 2018 summer exploration diamond drilling program
at the Bornite Project, a part of the Company’s Upper Kobuk Mineral Projects (“UKMP”) located
in the Ambler Mining District of Northwest Alaska . Assay results from these three holes
comprise approximately 2,888 meters from the 10,123-meter drill campaign. Two of the three
drill holes contain significant copper mineralization and were designed as infill and extension
holes to the 300 to 400 meter step-out holes drilled by the Company’s previous round of drilling
completed in 2017.
At a cutoff grade of 0.5% copper the results are as follows:
• RC18-0248 intersected five mineralized intervals of:
o 1.0 meter averaging 14.38% copper;
o 21.3 meters averaging 1.73% copper;
o 21.0 meters averaging 0.93% copper;
o 15.1 meters averaging 1.32% copper; and
o 4.9 meters averaging 2.97% copper.
• RC18-0249 intersected one mineralized interval of:
o 38.3 meters averaging 1.12% copper.
• RC18-0250 did not contain any significant mineralization.
On August 23, 2018, the Company announced initial assay results from the first drill hole,
RC18-0247, from the Bornite Project. Subsequently, on October 9, 2018, the Company
announced additional assay results for four drill holes (RC18 -0243, RC18-0244, RC18-0246
and RC18-0247).
Rick Van Nieuwenhuyse, President and CEO of Trilogy Metals commented , “Out of the two
dozen holes that reached target depth that we drilled during the 2017 and 2018 programs,
only one - hole RC18-0250, didn’t hit significant mineralization. All the other holes intersected
good grades over potentially mineable widths. In addition, we continue to see a significant
cobalt component to the mineralization. We are still exploring for the edges of this Mount
Isa/Central African Copper belt look-alike system.”
“Furthermore, I would also like to congratulate Governor -elect Michael Dunleavy. The
Governor-elect held his first press conference at the Alaska Miners Annual Convention where
he emphasized that ‘Alaska was open for business’ and that he ‘Wants to see more mines in
Alaska’. We look forward to working with Governor-elect Dunleavy, and his administration, to
permit and finance the Ambler Mining District Industrial Access Road and to advance the Arctic
and Bornite Projects towards production.”

This year’s program was comprised of 12 drill holes totaling approximately 10, 123 meters
through a combination of infill and expansion drill holes in and around the known deposit. The
original drilling campaign was budge ted to be 8,000 meters but was subsequently expanded
to 10,000 meters with the addition of two more drill rigs. The 2018 program followed up on
drilling completed during the 2017 exploration program, which was one of the larger programs
in the history of drilling at the Bornite Project. During 2017, the Company drilled nine diamond
drill holes comprising 8,437 meters to test the extension of the of the currently defined
resource†.
Additional drill results are anticipated to be released within the next few weeks as they become
available. The objective of the 2018 drill campaign is to infill and expand the currently defined
open pit and underground mineral resources.
Results are presented in Table 1 at a cutoff grade of 0.5% copper to be comparable with
previous drill results released by the Company. All the intersected widths are normal to
stratigraphy and therefore can be considered to be true widths. Results at a more selective
higher-grade cutoff of 1.5% copper are also presented in Table 2 to show locally higher-grade
intervals. Table 3 shows drill hole locations. Figure 1 shows the location of the drill holes
on a plan map and Figure 2 shows a cross-section through drill hole RC18-0248 and Figure
3 shows a cross-section through drill holes RC18-0249.

Mineralization within the Bornite deposit occurs as a series of “Reefs” hosted by both the Upper
and Lower Bornite Carbonate sequences separated by generally unmineralized phyllite unit s.
The Cu-Co mineralization at Bornite occurs in three distinct carbona te zones, the Upper Reef,
the Lower Reef, and the South Reef. All three zones were drill tested this year.
Mineralization is typically observed as breccia matrix replacement and is generally dominated
by chalcopyrite and sometimes by bornite with chalc ocite – particularly in the higher -grade
zones. Mineralization can also be observed as vein and replacement zones containing
chalcopyrite and calcite/dolomite gangue. These styles of mineralization were observed in all
holes mentioned in this press release with chalcopyrite, bornite, and chalcocite mineralization
observed in RC18 -0248 and RC18-0249. Drill hole RC18 -0250 contained very minor
chalcopyrite mineralization. Of particular interest, are two narrow but high grade intervals in
RC18-0248 (0.69m grading 21.08% Cu and 0.04% Co) and RC18 -0249 ( 0.13m grading
31.6%Cu, and 0.01% Co). These narrow high grade intervals are not vein style mineralization
but represent replacement style mineralization along bedding.
Bornite Resource
The resource estimate utilized assay data from drill holes completed by the Company between
2011 and 2013 and re-sampled historic holes Kennecott drilled in the 1960s and 1970s. Assays
from historic Ken necott holes that were not re -sampled were also used in the resource
estimation. On June 5th, 2018 the Company announced an updated resource estim ate for the
Bornite project of 5.5 billion pounds of copper inferred resource at a grade of 1.74% Cu and
7
Trust | Respect | Integrity
913 million pounds of copper indicated resource at a grade of 1.02% Cu and total inferred
cobalt resources (in-pit and below-pit) of 182.4 million tonnes grading 0.019% Co for 77 million
pounds of contained cobalt. Trilogy Metals filed a National Instrument 43-101 technical report
in July 2018. See the Bornite Technical Report as well as the Company’s press releases dated
June 5, 2018 (https://Trilogy PR June 5 2018) and the Company’s press release on the filing
of the updated NI43-101 Technical Report for Bornite on July 20, 2018 (https://Trilogy PR July
20 2018).
QA/QC Program
The drill program, sampling protocol and data verification were managed by qualified persons
employed by the Company. Diamond drill holes were typically collared at PQ or HQ diameter
drill core and reduced to HQ and NQ diameter during the drilling process. Samples were
collected using a 0.2 -meter minimum length, 2.5 -meter maximum length and 1. 9-meter
average sample length. Drill core recovery averaged 93% overall and 95% within the
prospective lithologies. 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 half 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 a
facility certified as ISO 9001:2008 and accredited to ISO / IEC 17025:2005 from the Standards
Council of Canada. The Company will submit 5% of the assay intervals from prospective
lithologies to an independent check assay lab.

About Trilogy Metals
Trilogy Metals Inc. is a metals exploration and development 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 volcanogenic massive sulphide
(“VMS”) deposits that contain copper, zinc, lead, gold and silver, and carbonate replacement
deposits which have been found to host high -grade copper and cobalt 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 Amble r mining
district in cooperation with local communities. Our vision is to develop the Ambler mining
district into a premier North American copper producer.
