October 5, 2018 - Vancouver, British Columbia – Trilogy Metals Inc. (TSX / NYSE American: TMQ) (“Trilogy”, "Trilogy Metals” or "the Company”) is pleased to report its third quarter results for the period ended August 31, 2018. Details of the Company's financial results are contained in the unaudited interim consolidated financial statements and Management's Discussion and Analysis which will be available on the Company's website at www.trilogymetals.com, on SEDAR at www.sedar.com and on EDGAR at www.sec.gov. All amounts are in United States dollars unless otherwise stated.

Third Quarter 2018 Highlights:

• Strong cash position of $30.5 million and working capital of $27.2 million.
• On June 5, 2018 the Company announced a maiden cobalt resource of 182.4 million tonnes grading 0.019% Co for 77 million pounds of inferred resources (see Table 1 for details).
• On July 20, 2018 the Company announced the filing of an updated technical report for the Bornite Project incorporating the cobalt resource and updates from the 2017 drill program at the Bornite Project.
• On August 23, 2018 the Company announced an expansion of the Bornite drilling program, with its partner, South32 Limited (ASX, LSE, JSE: S32; ADR: SOUHY) (“South32”), funding an additional $800,000 for the Company to add two drill rigs, which have subsequently completely four holes totaling approximately 2,170 meters.

The 2018 program and budget at the Bornite Project which was originally $10 million, includes in-fill and off-set drilling to better define and expand the high-grade copper resources at Bornite, was increased during the quarter to $10.8 million with a focus on adding additional drilling towards the end of the field program.Camp opened during mid-May and a seismic program was completed in early June.Results from the seismic program have now been received and the technical teams at the Company and South32 intend to meet later this year to review and analyze the information collected.

Three drill rigs started up in June to complete a planned field program of approximately 8,000 meters of drilling.Two drill rigs were added towards the end of the field season for an additional 2,170 meters of drilling.Initial assay results from hole RC18-0247 were released in a press release dated August 23, 2018 with results from the remainder of the drilling program anticipated to be released throughout the fall.Drilling at the Bornite Project completed on September 19, 2018.

The 2018 program and budget at the Arctic Project of $6.7 million includes the work performed to date on the Arctic PFS and work to advance the Arctic Project towards feasibility and permitting.In May 2018, the Company completed an ore sorting test at the Steinert facility in Walton, Kentucky and a summary report has been received from Steinert.The Company and Ausenco are reviewing operating and capital cost implications of incorporating ore sorting into the overall design to decide if ore sorting will be included into the final feasibility design or not.Results from this review are expected by the end of the year.One drill started up in June at Arctic to collect feasibility level geotechnical and hydrological data for the tailings dam and waste storage facility sites identified in the Arctic PFS.Approximately 695 meters of geotechnical and hydrological drilling was completed.Engineering studies are planned to include additional metallurgical, tailings and waste dump design, water treatment and water balance studies to support permitting and the feasibility study.In addition, we continue to collect baseline environmental data on hydrology, meteorology and archeology.We are preparing for the submission of permits for the Arctic mine in 2019.

We will be continuing to work closely with The Alaska Industrial Development and Export Authority (“AIDEA”) (the proponent for the Ambler Mining District Industrial Access Project (“AMDIAP”)) to advance the permitting process on the AMDIAP throughout 2018.On April 30, 2018 the Bureau of Land Management (“BLM”) released the Ambler Road Environmental Impact Statement Scoping Summary Report.Permitting of the AMDIAP under the National Environmental Policy Act’s Environmental Impact Statement (“EIS”) process has now concluded the “Scoping Phase” of permitting and has moved to the “Draft EIS Phase”.Per the BLM’s website, the Draft EIS is scheduled to be released for public comment by the end of March 2019.

Selected Results

The following selected financial information is prepared in accordance with U.S. GAAP.

in thousands of dollars,
except for per share amounts

For the three months ended August 31, 2018, Trilogy reported a net loss of $9.9 million (or $0.08 basic and diluted loss per common share) compared to a net loss of $9.0 million for the corresponding period in 2017 (or $0.09 basic and diluted loss per common share).This variance was primarily due to the difference in mineral properties expense due to the size and timing of the field programs. An increase of $0.6 million of mineral property expenses occurred during the three months ended August 31, 2018 compared to the three months ended August 31, 2017.

Other differences noted for the comparable periods were i) an increase in general and administrative expenses to support the increased field program at the UKMP; ii) a slight decrease in professional fees as legal fees associated with an equity financing in the second quarter have all been capitalized under share issue costs; iii) an increase in salaries and stock-based compensation due to new hires in the quarter as well as the granting of additional stock options; and iv) a decrease in investor relations expenses as costs associated with the analyst tours of the projects have been captured under general and administrative expenses.

The basic and diluted loss per common share of $0.08 for the three months ended August 31, 2018 has decreased from the basic and diluted loss per common share of $0.09 for the three months ended August 31, 2017 due primarily by the activities affecting the loss for the period as described above, offset by an increase in the weighted average number of shares outstanding for the three months ended August 31, 2018.

For the nine months ended August 31, 2018, Trilogy reported a net loss of $16.5 million (or $0.14 basic and diluted loss per common share) compared to a net loss of $14.4 million for the corresponding period in 2017 (or $0.14 basic and diluted loss per common share).This variance was primarily due to the increased activity level at our projects which are recorded as mineral properties expense.An increase of $2.3 million of mineral property expenses occurred during the nine months ended August 31, 2018 compared to the nine months ended August 31, 2017 due to the work performed for the Arctic PFS in 2018 with no comparable activity in 2017.Similar to the activity levels for the three months ended August 31, 2018, other differences noted relate to i) a small increase in general and administrative expenses; ii) a decrease in professional fees as legal costs related to the financing completed on April 20, 2018 are recorded as issuance costs in shareholders equity; iii) and a slight increase in salaries due to new hires as well as a significant increase in stock based compensation due to the accelerated amortization of new options that were granted during the nine month period ended August 31, 2018.

The basic and diluted loss per common share of $0.14 for the nine months ended August 31, 2018 is consistent with the basic and diluted loss per common share of $0.14 for the nine months ended August 31, 2017. The operating activities increasing the loss as described above have been offset by the dilutive effect of an increase in the weighted average number of shares outstanding for the nine months ended August 31, 2018.

Bornite Project

On June 5, 2018 the Company announced a maiden cobalt resource with the following highlights:

• At a base case 0.50% copper cut-off grade, and within the combined Indicated and Inferred Cu resource pit shell, the Bornite Project is estimated to contain in-pit Inferred Resources of 124.6 million tonnes grading 0.017% Co for 45 million pounds of contained cobalt (see Table 1 for details).
• Below the resource limiting pit shell and at a base case cut-off grade of 1.5% copper, the Bornite Project is estimated to contain additional Inferred Resources of 57.8 million tonnes grading 0.025% Co for 32 million pounds of contained cobalt.
• Total Inferred Resources (in-pit and below-pit) of 182.4 million tonnes grading 0.019% Co for 77 million pounds of contained cobalt (see Table 1 for details).

Table 1: Estimate of Cobalt Mineral Resources for the Bornite Deposit

1. Resources stated as contained within a pit shell developed using a metal price of US$3.00/lb Cu, mining costs of US$2.00/tonne, milling costs of US$11/tonne, G&A cost of US$5.00/tonne, 87% metallurgical recoveries and an average pit slope of 43 degrees.
2. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. There is no certainty that all or any part of the Mineral Resources will be converted into Mineral Reserves.
3. It is reasonably expected that the majority of Inferred mineral resources could be upgraded to Indicated mineral resources with additional exploration.
4. See “Cautionary Note to United States Investors”.

Non-GAAP Performance Measures
Some of the financial measures referenced in this press release are non-GAAP performance measures.We have not reconciled forward-looking full year non-GAAP performance measures contained in this news release to their most directly comparable GAAP measures, as permitted by Item 10(e)(1)(i)(B) of Regulation S-K. Such reconciliations would require unreasonable efforts at this time to estimate and quantify with a reasonable degree of certainty various necessary GAAP components, including for example those related to future production costs, realized sales prices and the timing of such sales, timing and amounts of capital expenditures, metal recoveries, and corporate general and administrative amounts and timing, or others that may arise during the year. These components and other factors could materially impact the amount of the future directly comparable GAAP measures, which may differ significantly from their non-GAAP counterparts.

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”). 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 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.Guide 7 does not define and 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. U.S. investors should also understand that “inferred mineral resources” have a great amount of uncertainty as to their economic and legal feasibility. Under Canadian rules, subject to certain exceptions, estimated “inferred mineral resources” may not form the basis of feasibility or pre-feasibility studies. 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 any reserves reported by us in the future in compliance with NI 43-101 may not qualify as “reserves” under SEC standards. Accordingly, information concerning mineral deposits set forth herein may not be comparable to information made public by companies that report in accordance with United States standards. Accordingly, information concerning mineral deposits set forth herein may not be to similar information made public by United States companies subject to reporting and disclosure requirements under United States federal securities laws and the rules and regulations thereunder.
