News Release

Draft Environmental Impact Statement and Environmental and

Economic Analysis filed for the Ambler Road

August 26, 2019 - Vancouver, British Columbia – Trilogy Metals Inc. (TSX/NYSE

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

release of the Draft Environmental Impact Statement by the United States Bureau of Land

Management (“BLM”) for the Ambler Mining District Industrial Access Project or AMDIAP

(Ambler Access Road) and the Environmental and Economic Analysis by the United States

National Park Service (“NPS”) for that portion of AMDIAP that traverses the Gates of the Arctic

National Park and Preserve.

Ambler Mining District Industrial Access Project (“AMDIAP”)

On August 23, 2019 the BLM, the lead agency for the permitting of the Ambler Mining District

Industrial Access Project (“AMDIAP”), completed the Draft Environmental Impact Statement

(“EIS”) which has been posted on the BLM website (see below). Also, the NPS, which is a

cooperating agency, has completed and posted the Environmental and Economic Analysis

(“EEA”) on the National Park Service website. The EEA will evaluate the two alternative routes

for the AMDIAP – the shortest overall AMDIAP route and the shortest route across the NPS

Preserve lands.

The next step is a public comment period which will be held over 45 days. Comments on the

Draft EIS will be accepted through Oct ober 15, 2019 with meetings scheduled to commence

on September 10, 2019 in Alaska.

For more information on the Draft EIS please visit the BLM website at

https://www.blm.gov/alaska. Information on the EEA can be found at

https://www.nps.gov/gaar/learn/management/ambler-row.htm.

Rick Van Nieuwenhuyse, President and CEO of Trilogy Metals commented, “The release of the

draft EIS by the BLM and the EEA is a critical milestone for the permitting of the AMDIAP which

would allow the exploration and development of the Ambler Mining District and our Upper

Kobuk Mineral Projects specifically. I am also pleased that the NPS has completed the EEA.

The EEA is also a critical document in that it examines the two proposed routes that will

traverse the Gates of the North Preserve. Trilogy looks forward to engaging in this process

which will give all stakeholders an opportunity to have a voice in the permitting of the AMDIAP.”

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 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 h ectares. 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 Ambler mining district in cooperation with local

communities. Our vision is to develop the Ambler mining district into a premier North American

copper producer.

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,

as amended (“CIM Definition Standards”). C anadian 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 m ade that the

mineralization could be economically and legally produced or extracted at the time the reserve determination is made.

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.
