Trilogy Metals Announces the 2022 Program and Budget for the Upper Kobuk Mineral Projects and Provides Update on Arctic Permitting

Highlights of the Approved 2022 Program

• Approximately $28.5 million budget fully funded by Ambler Metals
• Up to 10,000 meters to be allocated between resource development drilling at the Arctic Project and priority drill-ready exploration targets in the district
• Engineering studies advancing the Arctic Project
• Submission of the Federal 404 permit application in early 2022

Proposed 2022 Arctic and UKMP Drilling Program

A two-day technical review of the 2021 exploration program, involving geologists from Trilogy, South32 and Ambler Metals, was held in Fairbanks, Alaska on December 8 and 9, 2021. Ambler Metals presented technical results received to date and a preliminary outline of the 2022 exploration program. A full technical review of the 2021 exploration results and ranking of drill targets and target areas for the 2022 field season will be held in early 2022 once all assay results have been received, compiled, and interpreted.

The 2022 budget for Ambler Metals, approved by the owners, Trilogy and South32, will cover up to 10,000 meters of helicopter-supported diamond drilling that is expected to commence in early June. The meterage will be divided between resource development drilling at Arctic and scout drilling of both Volcanogenic Massive Sulphide ("VMS") targets in the Ambler Belt, with a focus on targets near Arctic, and Carbonate-Hosted Copper targets around Bornite and the Cosmos Hills. A greater effort on the ground to identify and evaluate new targets for drilling, including the use of ground and down-hole electro-magnetic (EM) surveys, is planned.

Arctic Permitting

An independent consulting company has completed a preparedness review of the draft permitting package for the Arctic Project and presented the results of this review to the technical teams of South32 and Trilogy. The review concluded that the Ambler Metals permitting strategy is sound and the permitting package can proceed with minor changes. Ambler Metals is now making the recommended changes to the permitting package and expects to file the permitting application, which will start the formal permitting process for the Arctic Project, with the United States Army Corps. of Engineers ("USACE") in early 2022.

Given that the Arctic Project is located on state and private land, the key federal permit will be the 404 Dredge or Fill Permit that is issued by the USACE, the lead agency during the federal permitting process. The permitting process will be carried out in accordance with the National Environmental Policy Act. In parallel with the federal permitting process, the State of Alaska, specifically the Alaska Department of Environmental Conservation, Alaska Department of Natural Resources and Alaska Department of Fish and Game, will be the state agencies responsible for issuing the state permits which include the Mine Operating Permit, the Air Quality Permit, the Dam Construction and Operating Permits, and the Water Discharge Permit. There will also be other permits issued by the Northwest Arctic Borough. The Company expects to file the permit application during the first quarter of 2022, and for the overall permitting process to take 24 to 30 months to be completed.

More details on the proposed 2022 program and Arctic permitting timeline will be made public in early 2022.

Tony Giardini, President and CEO of Trilogy, commented, "We are pleased that we are continuing to make progress on de-risking the Arctic Project and that we are now very close to commencing the formal permitting activities. Senior management at Trilogy Metals is working very closely with representatives from South32 and Ambler Metals in devising a 2022 program that will greatly assist in moving the Arctic Project forward and to continue to add value through the drill bit. We believe that 2022 will be another significant year for the Company."

About Trilogy Metals

Trilogy Metals Inc. is a metal exploration and development company which holds a 50 percent interest in Ambler Metals LLC which has a 100 percent interest in the Upper Kobuk Mineral Projects ("UKMP") 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 which 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 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.
