Trilogy Metals Reports Drilling Results from the Bornite Project

October 9, 201 8 - Vancouver, British Columbia – Trilogy Metals Inc. (TSX/NYSE

American: TMQ) ("Trilogy Metals” or the “Company”) is pleased to announce the first set of

high-grade copper and cobalt assay results from this summer’s exploration diamond drilling

program at the Bornite Project, a part of the Company’s Upper Kobuk Mineral Project s

(“UKMP”) located in the Ambler mining district of Northwest Alaska. Sample results from these

four holes comprise approximately 3,871 meters from the recently completed 10,123 meter

drill campaign. All four drill holes contain copper mineralization and were designed as infill

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:

• RC18-246 intersected three mineralized intervals of:

o 19.6 metres averaging 2.06% copper;

o 6.1 metres averaging 2.36% copper; and

o 7.6 metres averaging 1.04% copper.

• RC18-243 intersected one mineralized interval of:

o 2.0 metres averaging 2.23% copper.

• RC18-244 intersected one mineralized interval of:

o 20.4 metres averaging 0.83% copper.

• RC18-247 intersected two mineralized intervals of:

o 20.1 metres averaging 4.55% copper, including 16.4 meters grading 5.34%

Copper and 0.21% Cobalt (The results of this mineraliz ed interval were

disclosed in the Company’s press release dated August 23, 2018); and

o 33.4 metres averaging 0.82% copper.

Rick Van Nieuwenhuyse, President and CEO of Trilogy Metals commented, “We continue to see

narrow zones of high -grade copper and cobalt mineralization overlain by broader zones of

lower grade mineralization at Bornite. The continuity of the mineralized envelop continues to

impress. With another eight holes of results due to come out over the next several weeks, we

will continue to release results as they become available. After all results are in, we expect to

complete an updated resource estimate at Bornite in the first half of next year.”

The 2018 drilling budget of $10 million for Bornite this year was funded entirely by Sout h32

Limited (ASX, LSE, JSE: S32; ADR: SOUHY) (“South32”) and represents the second $10 million

payment under the Option Agreement with South32 and maintains the Option Agreement in

good standing. In August 2018, South32 agreed to increase its contribution to this year’s

Bornite drilling program by funding an additional $800,000 to the Company for an increased

budget at Bornite totaling $10.8 million, which allowed the Company to expand drilling from

8,000 meters to 10,000 meters this summer. The additiona l funding will reduce South32’s

2019 minimum exploration budget commitment of $10 million to $9.2 million. For more

information on the Option Agreement see the Company’s press release on April 10, 2017

(https://Trilogy PR April 10 2017).

This year’s program was comprised of 12 d rill 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 budgeted to be 8,000 metres but was subsequently expanded

to 10,000 metres with th e 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 metres to test the extension of the of the currently defined

resource†.

Trilogy Metals has recently completed its summer exploration drilling program at Bornite and

geotechnical activities at its Arctic Project. Additional drill results are anticipated to be released

regularly over the next couple of months 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 selec tive

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 RC18-0246.

Figure 2 – Cross Section of Bornite Drilling Showing RC18-246 Results

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 carbonate 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 g enerally dominated

by chalcopyrite and sometimes by bornite with chalcocite – 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 bornite, chalcocite mineralization observed in RC18-

0247, RC18-0246, and minorly within RC18-0244; and chalcopyrite dominating mineralization

observed in RC18-0243.

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 . 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 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 cobal t. 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 release s 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 -metre minimum length, 2.5 -metre maximum length and 1. 8-metre

average sample length. Drill core recovery averaged 87% overall and 9 4% 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.

Cautionary Note to United States Investors

This press release has been prepared in accordance with the requirements of the securities laws in effect in Canada,

which differ from the requirements of U.S. securities laws. Unle ss otherwise indicated, all resource and reserve

estimates included in this press release have been prepared in accordance with Canadian National Instrument 43-101

Standards of Disclosure for Mineral Projects (“NI 43 -101”) and the Canadian Institute of Min ing, Metallurgy and

Petroleum (CIM)—CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council,

as amended (“CIM Definition Standards”). NI 43 -101 is a rule developed by the Canadian Securities Administrators

which establishes standards for all public disclosure an issuer makes of scientific and technical information concerning

mineral projects. Canadian standards, including NI 43 -101, differ significantly from the requirements of the United

States Securities and Exchange Commission (SEC), and resource and reserve information contained herein may not

be comparable to similar information disclosed by U.S. companies. In particular, and without limiting the generality of

the foregoing, the term "resource” does not equate to the term "reserves”. Under U.S. standards, mineralization may

not be classified as a "reserve” unless the determination has been made that the mineralization could be economically

and legally produced or extracted at the time the reserve determination is ma de. The SEC's disclosure standards

normally do not permit the inclusion of information concerning "measured mineral resources”, "indicated mineral

resources” or "inferred mineral resources” or other descriptions of the amount of mineralization in mineral d eposits

that do not constitute "reserves” by U.S. standards in documents filed with the SEC. Investors are cautioned not to

assume that all or any part of “measured” or “indicated resources” will ever be converted into “reserves”. Investors

should also understand that "inferred mineral resources” have a great amount of uncertainty as to their existence and

great uncertainty as to their economic and legal feasibility. Under Canadian rules, estimated "inferred mineral

resources” may not form the basis of feasibility or pre-feasibility studies except in rare cases. Disclosure of "contained

ounces” in a resource is permitted disclosure under Canadian regulations; however, the SEC normally only permits

issuers to report mineralization that does not constitute "reserves” by SEC standards as in-place tonnage and grade

without reference to unit measures. The requirements of NI 43 -101 for identification of "reserves” are also not the

same as those of the SEC, and reserves reported by Trilogy Metals in compliance with NI 43-101 may not qualify as

"reserves” under SEC standards. Arctic does not have known reserves, as defined under SEC Industry Guide 7.

Accordingly, information concerning mineral deposits set forth herein may not be comparable with information made

public by companies that report in accordance with U.S. standards.
