News Release

Permitting Advances on Ambler Access Road

March 6, 2017 - Vancouver, British Columbia – Trilogy Metals Inc. (TSX, NYSE-MKT:

TMQ) ("Trilogy Metals” or "the Company”) is pleased to announce that the permitting process

is advancing on the Ambler Mining District Industrial Access Project (“AMDIAP”). The Notice of

Intent (“NOI”) initiating the permitting process under the National Environmental Policy Act

(“NEPA”) for the preparation of an Environmental Impact Statement (“EIS”) on the AMDIAP

was published on February 28, 2017 by the Bureau of Land Management (“BLM”) in the U.S.

Federal Register. The BLM is the lead Federal agency for the EIS. This notice initiates the public

scoping process for the EIS with comments due by May 30, 2017.

The Notice of Intent states that the various federal and state agencies intend to prepare an EIS

for Federal authorization to construct and operate an approximately 211-mile long industrial

access road in the southern Brooks Range foothills of Alaska, originating at the Dalton Highway

and ending at the Ambler River and providing access to the Ambler Mining District. The BLM

has announced the beginning of the EIS scoping process to solicit public comments and

identify issues. The BLM intends to coordinate the development of the EIS with the National

Park Service (“NPS”), which is in accordance with the Alaska National Interest Lands

Conservation Act (“ANILCA”). The NPS is developing a separate environmental and economic

analysis (“EEA”) solely for the purpose of determining the most desirable route for that portion

of the proposed road right-of-way that would cross the Gates of the Arctic National Preserve.

The AMDIAP is anticipated to provide surface access to the Ambler Mining District, long known

to contain significant deposits of copper, lead, zinc, gold and silver and specifically including

the Company’s Upper Kobuk Mineral Projects – Arctic and Bornite. Through an Exploration and

Option to Lease Agreement with NANA Regional Corporation, Inc. (“NANA”), Trilogy has the

exclusive rights to enter and explore their Bornite Lands and ANSCA Lands. Further NANA and

Trilogy have agreed to certain matters relating to the exploration and possible development,

construction and operation of a mine on the Bornite Lands, the ANCSA Lands and the Ambler

Lands contributed by the Company. In exchange for these rights, NANA receives a net smelter

royalty, a net profits share, and the option to participate as an equity owner in a mining

operation. This partnership also provides, among other things, scholarship funding,

contracting preferences for NANA companies and a focus on local workforce development.

Through a Memorandum of Understanding (“MOU”) the Company has been working with the

Alaska Industrial Development Export Authority ("AIDEA”) over the past several years to

identify and select a preferred access route into the Ambler Mining District and support

engineering and environmental studies as well as community outreach for the AMDIAP. Now

that AMDIAP is in the permitting phase, the Company intends to sign a new MOU with AIDEA

that sets the foundation to work together during this next permitting phase.

The AMDIAP is modeled on AIDEA’s successful DeLong Mountain Transportation System

(“DMTS”), which includes an industrial access road from the Red Dog Mine to the DMTS port.

AIDEA worked with private investors to finance construction of the DMTS industrial access

road, and the costs of road construction were paid back through tolls paid by the mine for use

of the road. No State of Alaska general funds were used to construct the DMTS and that is

exactly what is anticipated for the AMDIAP.

Rick Van Nieuwenhuyse, President and CEO of Trilogy Metals commented, “Having the BLM

initiate the permitting process is a major accomplishment and milestone for developing the

Ambler Mining District. Permitting in the United States under NEPA is a prescribed process

involving five recognized stages: Public Scoping to identify concerns; Preliminary Draft EIS

(draft permitting document); Draft EIS and Public Comment; Final EIS and Public Notice; and

finally a Record of Decision (“ROD”). This process has typically taken two to three years to

complete. However, with the issuance of Executive Order # 13766 (entitled: “Expediting

Environmental Reviews and Approvals for High Priority Infrastructure Projects”) under the new

Trump Administration which directs the federal agencies to coordinate an effort to streamline

the permitting process, particularly with respect to important infrastructure projects, we are

hopeful that the permitting timeline could be shortened. The Company plans to work closely

with AIDEA to accomplish this important objective.”

About Trilogy Metals

Trilogy Metals Inc., formerly NovaCopper Inc., is a metals exploration 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 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

The Arctic Preliminary Economic Assessment and the Bornite Technical Report have 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 National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101”) and the

Canadian Institute of Mining, Metallurgy, and Petroleum Definition Standards on Mineral Resources and Mineral

Reserves. 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 therein 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 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 filed with the SEC. Investors are cautioned not to assume that

any part or all of mineral deposits in these categories will ever be converted into reserves. U.S. 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. It cannot be assumed that all or any part of an "inferred mineral

resource” will ever be upgraded to a higher category. Under Canadian rules, estimated "inferred mineral resources”

may not form the basis of feasibility or pre-feasibility studies except in rare cases. Investors are cautioned not to

assume that all or any part of an "inferred mineral resource” exists or is economically or legally mineable. 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 the Company in compliance with NI 43-101 may not

qualify as "reserves” under SEC standards. Accordingly, information concerning mineral deposits set forth in this press

release or the Bornite Technical Report may not be comparable with information made public by companies that report

in accordance with U.S. standards.
