Trilogy Metals Provides Update on the Ambler Access Road Project's Supplemental Environmental Impact Statement

November 23, 2022 – Vancouver, British Columbia – Trilogy Metals Inc. (TSX/NYSE American: TMQ) ("Trilogy" or the "Company") is providing an update on the Ambler Access Project ("AAP") – the proposed 211-mile, industrial-use-only road from the Upper Kobuk Mineral Projects ("UKMP") to the Dalton Highway that will enable advancing exploration and development at the Ambler Mining District, home to some of the world's richest known copper-dominant polymetallic deposits.

On November 15, 2022, the United States Bureau of Land Management ("USBLM") submitted a status report in accordance with the Voluntary Remand dated May 17, 2022. The comment period ended on November 4, 2022 for the scoping process of the Supplemental Environmental Impact Statement ("SEIS"). The purpose of the SEIS is to further evaluate subsistence impacts to fish and caribou habitat and address the desire for additional tribal consultation. The USBLM is now evaluating the scoping comments and determining whether additional impacts, if any, should be more thoroughly assessed. A compilation of the substantive comments received will be assembled into a summary public scoping report and available on the USBLM website for public review.

The USBLM currently anticipates publishing a draft SEIS during the second quarter of calendar year 2023, which will be open for public comment upon publication. The USBLM also anticipates publishing a final SEIS, conducting final pre-decision consultation with Alaska Native Tribes and Corporations, and issuing a Record of Decision, all within the fourth quarter of calendar year 2023.

About Trilogy Metals

Trilogy Metals Inc. is a metal exploration and development company that holds a 50 percent interest in Ambler Metals LLC which has a 100 percent interest in the Upper Kobuk Mineral Projects in Northwestern Alaska. On December 19, 2019, South32, a globally diversified mining and metals company, exercised its option to form a 50/50 joint venture with Trilogy. The UKMP is located within the Ambler Mining District, one of the richest and most-prospective known copper-dominant districts 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 that 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 a land package that spans approximately 181,387 hectares. Ambler Metals has an agreement with NANA Regional Corporation, Inc., an Alaska Native Corporation that provides a framework for the exploration and potential development of the Ambler Mining District in cooperation with local communities. Trilogy's vision is to develop the Ambler Mining District into a premier North American copper producer while protecting and respecting subsistence livelihoods.
