Trilogy Metals Provides Update on Project Activities

March 19, 2019 - Vancouver, British Columbia – Trilogy Metals Inc. (TSX/NYSE

American: TMQ) (" Trilogy Metals ”, “Trilogy” or the “Company”) is pleased to provide an

update on its project activities. Preparations are already underway to prepare the Bornite camp

to accommodate the 2019 field programs on the Company’s 100%-owned Upper Kobuk Mineral

Projects located in Northwest Alaska. All amounts are in US dollars.

Bornite Project

Following the Company’s announcement on March 5, 2019 of the results from the metallurgical

program at the Bornite Project, the Company has now completed an analysis on the copper

and cobalt resource incorporating the updated copper and cobalt metallurgical results and the

drill results from the 2017 and 2018 drill campaigns. Results for the Bornite resource estimate

show that at an open pit cut -off grade of 0.5% copper and a below pit cut -off grade of 1.5%

copper, there is no significant change in the size and grade of the current resource estimate

at Bornite. These results also show that at a below pit cut-off grade of 0.5% copper, there is

the potential for a significant increase in lower grade copper mineralization. The 2017 and

2018 drilling campaigns at Bornite were focused on the expansions of the known deposit and

many of the drill holes are still too widely spaced apart to be included in an updated resource

estimate. See Table 1 and 2 for the Company’s current estimate of the copper and cobalt

mineral resources and the technical report titled “NI 43 -101 Technical Report on the Bornite

Project, Northwest Alaska, USA” with an effective date of June 5, 2018, released on July 20,

2018.

The 2019 program and budget of $9.2 million for Bornite will be mainly directed at i)

approximately 10,000 meters or 12 holes of infill and expansion drilling in the deposit; ii)

additional metallurgical work to optimize copper recoveries and the determination of next steps

for the recovery of cobalt; and iii) initial engineering studies to prepare Bornite for a preliminary

economic assessment once the work from the 2019 work programs are completed , including

drill results, metallurgical program updates, a resource update and ongoing environmental

baseline data collection.

Arctic Project

The Company has commenced preparations for the summer field season at the Arctic Project.

Specifically, the Company will continue to advance engineering and environmental work in

2019 in support of completing a feasibility study and preparing the Arctic Project for permitting.

The total budgeted amount for the se activities is estimated to be $7.0 million. The Company

will undertake additional hydrological and geotechnical work at the site along with water

management, tailings facility and waste rock containment analysis and design. Additional

metallurgical test work to verify ore hardness and grinding characteristics is currently on-going

with materials from the project. The Company expects to complete the feasibility study in the

first half of 2020.

Ambler District Exploration Program

The Company will complete a $2 Million exploration program along the 100-kilometer Ambler

volcanogenic massive sulphide (“VMS”) Belt funded equally by Trilogy and South32. Th is

program will include a district-wide VTEM and ZTEM geophysical surveys flown on 200 and 400

meter line spacing over both the Cosmos Hills and the Amble r Belt . Both surveys are

electromagnetic surveys that have proven to be successful in identifying targets and

mineralization in VMS districts. This survey is expected to start in mid-April and be completed

by the beginning of May. The data will then be processed to identify and prioritize drill targets

for follow up geologic mapping, soil geochemistry and drilling – including on known historic

resources previously identified along the 100-kilometer long belt (Figure 1).

Ambler Mining District Industrial Access Project

Over the last few months, the Company has been in contact with the various agencies involved

in the permitting of the Ambler Mining District Industrial Access Project (“AMDIAP”). According

to the Bureau of Land Management (“BLM”), which is the lead agency, the permitting of the

AMDIAP is moving along on schedule. The Preliminary Draft Environmental Impact Statement

(“EIS”) is expected to be made available to all the cooperating age ncies by the end of April

2019, including: the Bureau of Land Management, the US Army Corp of Engineers, the US Park

Service, the US Department of Transportation, the US Coast Guard and the US Fish and Wildlife

Service; State agencies – the Department of N atural Resources and the Department of

Environmental Conservation; the Northwest Arctic Borough; and several participating Tribal

entities. According to the BLM, the draft EIS is expected to go out for public comment during

the summer and be completed in the late summer/early fall 2019 with the final EIS expected

by the end of 2019. Shortly after the final EIS has been issued, the Company expects the BLM

to issue the Record of Decision for the Right -of-Way across federal BLM managed lands and

the Army Corp. of Engineers to issue the 404 Wetlands Dredge and Fill Permit as per the Clean

Water Act.

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. Unless 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 Mining, Metallurgy and

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

6

Trust | Respect | Integrity

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 ma y 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 made. 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 deposits

that do not constitute "reserves” by U.S. standards in documents fi led 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 no t 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.
