Exhibit 99.1

Draft Environmental Impact Statement and Environmental and Economic Analysis filed for the Ambler Road

VANCOUVER, Aug. 26, 2019 /CNW/ - 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 October 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."

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 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 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"). 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 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.
