Insights
Trilogy advances Arctic permitting and funds 2026 drilling, with sizable modeled regional economic benefits.
Trilogy Metals, through Ambler Metals, has moved the Arctic Project into formal U.S. federal permitting by filing a Clean Water Act Section 404 application. Potential FAST-41 coverage could coordinate agency reviews on a defined timetable, which may help organize the long lead-time steps toward mine construction.
The 2026 field season is fully funded within a $35 million budget and targets 40–45 drill holes totaling about 5,650 meters, aimed at final engineering for Arctic and preparing the Bornite camp and regional targets. This keeps technical work progressing ahead of any future construction decision.
An independent study cited in the disclosure estimates Arctic construction and operations could support up to 870 jobs, over $31 million in annual state taxes and fees, and up to $3.4 million per year in reduced transportation costs for remote villages. These figures are based on feasibility assumptions and will ultimately depend on permitting outcomes, investment decisions, and realized metals prices.

Exhibit 99.1
Trilogy Metals Announces Commencement of Permitting for High-Grade Arctic Copper-Zinc-Lead-Gold-Silver Project in Alaska
Fully Funded Exploration and Development Field Program by Ambler Metals Anticipated to Commence in May
Independent Economic Impact Study Highlights Arctic's Substantial Benefits to Alaska and the Northwest Arctic Region
All amounts are in United States dollars unless otherwise stated.
VANCOUVER, BC, April 21, 2026 /CNW/ - Trilogy Metals Inc. (NYSE American: TMQ) (TSX: TMQ) ("Trilogy Metals", "Trilogy" or the "Company") announced today that Ambler Metals LLC ("Ambler Metals"), its 50/50 joint venture with South32 Limited ("South32"), has commenced the permitting process for the Arctic Project (the "Arctic Project" or "Arctic"), part of the Upper Kobuk Mineral Projects ("UKMP") in northwestern Alaska's Ambler Mining District. Arctic is one of the highest-grade, undeveloped open-pittable copper deposits in the world, with an estimated average grade of approximately 5% copper equivalent1,2, bolstered by material precious metals by-product credits.
Ambler Metals has submitted an application for a Clean Water Act Section 404 permit with the U.S. Army Corps of Engineers ("USACE"), thereby initiating federal permitting for mine development and operations at Arctic. In addition to this application submission, Ambler Metals plans to request an eligibility review for coverage under the Title 41 of the Fixing America's Surface Transportation Act program ("FAST-41"), administered by the Federal Permitting Improvement Steering Council. FAST-41 coverage would provide a comprehensive, integrated permitting timetable and bring greater transparency to the project through the federal Permitting Dashboard.
Tony Giardini, President and CEO of Trilogy, commented: "Requiring a Section 404 permit from the USACE under the Clean Water Act streamlines the Arctic Project's federal permitting pathway. All other significant permits are issued at the state and local levels, concentrating federal review into a single, well-defined process while maintaining rigorous environmental oversight.
"By potentially leveraging the FAST-41 program, the Arctic Project benefits from a level of inter-agency coordination and timeline accountability that was historically unavailable to large-scale resource developments. This process transforms often fragmented federal reviews into a synchronized, transparent schedule, providing our stakeholders with a clear window into the permitting roadmap. For Trilogy, FAST-41 coverage means that achieving regulatory milestones is supported by a predictable and transparent path toward project financing and construction.
"An independent economic impact analysis prepared by McKinley Research Group ("MRG")3 confirms what we have long believed - the Arctic Project is a generational economic opportunity for Alaska and particularly for Northwest Arctic communities. The study estimates that Arctic mine construction and operations will support up to 870 jobs statewide, generate more than $31 million in annual state taxes and fees, and deliver meaningful revenue to NANA Regional Corporation through royalties and preferential shareholder employment. Perhaps most importantly, the Ambler Access Project road has the potential to reduce transportation costs for remote Alaska Native villages by up to $3.4 million per year, cutting heating fuel transportation costs by as much as 70% and reducing the cost of building a home in the Upper Kobuk region by nearly 40%. These are tangible, life-changing benefits for communities that face some of the highest costs of living in the United States.
"We are also excited to kick off the 2026 summer field season next month to conduct geotechnical and exploration drilling, along with general camp maintenance and capital improvements to support future programs. This field season is particularly important as it will allow Ambler Metals to carry out engineering, environmental, and technical work required to support a final investment decision to advance this critical minerals asset toward production.
"It's important to note that Arctic is just the first phase for this multi-generational American mining district. There are currently 30 known volcanogenic massive sulfide ("VMS") occurrences across this highly prospective and under-explored mineral belt. Arctic's strong cash-flow potential at spot metal prices will be the key to unlocking the district, and we fully expect exploration and development efforts to ramp up in the coming years across the UKMP, including at the high-grade Bornite copper-cobalt project ("Bornite"). The future looks extremely promising for one of the most strategic and mineral-rich districts in the United States."
Fully Financed Ambler Metals Field Program to Commence in May; Expected to Advance Arctic Towards Construction Decision and Prepare for Accelerated District-Wide Exploration in 2027
Ambler Metals is finalizing plans for the 2026 field season, and camp and drill mobilization by the end of May. The fully financed field campaign, part of Ambler Metals' $35-million 2026 budget, is expected to include 40 to 45 drill holes aimed at advancing final engineering plans for Arctic mine development. The program will also focus on re-establishing the exploration camp at the Bornite deposit, with the intention of ramping up exploration and development activities at the site in 2027, as well as commencing district-wide drill target assessments that will underpin future regional exploration programs across the mineral belt.
The drill campaign at Arctic is targeting at least 5,650 meters, with a focus on geotechnical and hydrogeological sites to underpin mine design and support permitting. Some of these drill holes will be extended to test deeper exploration targets that are located along the favourable Arctic mineral horizon. These exploration targets are within 3 to 4 kilometers (2 to 2.5 miles) of the Arctic deposit and include airborne electromagnetic (VTEM and ZTEM) anomalies that are potentially related to VMS mineralization.
Field work at the Bornite camp will mainly focus on preparing the site for accelerated exploration and development activities in the coming years. Bornite is a carbonate-hosted copper-cobalt deposit approximately 25 kilometers (15 miles) southwest of the Arctic Project (see Figure 1), which is forecasted to produce 1.9 billion pounds of copper over a 17-year mine life4,5 and has the potential to extend copper mining activities to over 30 years. Bornite has characteristics similar to a series of districts and deposits, including the Mount Isa district in Australia, the Tynagh deposit in Ireland, the Kipushi deposit in the Democratic Republic of the Congo, and the Tsumeb deposit in Namibia.
Finally, the field program will include regional exploration work to advance known mineral occurrences and targets along the broader UKMP, with the intention of preparing targets for potential drilling in 2027. The mineral belt hosts numerous historic VMS mineral occurrences and electromagnetic anomalies that demonstrate high prospectivity for future discovery, which will be the focus of future regional exploration campaigns across the 100-kilometer-long (60-mile-long) VMS belt.

Independent Economic Impact Study Highlights Arctic's Substantial Benefits to Alaska and the Northwest Arctic Region
An independent economic impact analysis prepared by MRG for Ambler Metals quantifies the broad economic contributions of developing the Arctic Project and establishing surface transportation access to the Ambler Mining District. The study draws on the Arctic Feasibility Study, regional socioeconomic data, and peer benchmarking against Teck Resources Limited's Red Dog Mine, which has operated on NANA lands in Northwest Alaska since 1989.
Key findings from the MRG study include:
| • | Construction-phase employment and wages: Arctic mine construction is expected to directly support an annual average of 500 workers over a three-year period, with a peak workforce of approximately 650, and cumulative direct wages of approximately $160 million. Including indirect and induced multiplier effects, construction activity is estimated to support an average of 750 jobs annually and cumulative wages of approximately $220 million across Alaska. |
| • | Operations-phase employment and wages: Over the 13-year mine life as contemplated in the Arctic Feasibility Study, operations are expected to directly create approximately 430 jobs paying approximately $60.2 million in annual wages, and to support approximately 870 total jobs and approximately $89.8 million in annual wages statewide when indirect and induced effects are included. |
| • | NANA shareholder hires and royalties: Consistent with Red Dog Mine benchmarks, the Arctic mine is expected to employ approximately 230 NANA shareholders annually under a preferential hiring framework. Under the existing Exploration Agreement and Option to Lease, NANA is entitled to a 1% net smelter royalty, expected to total approximately $85.7 million over the mine life using Feasibility Study metal price assumptions. NANA also retains the option to acquire a 16% to 25% direct interest in Arctic, or alternatively to receive a 15% net proceeds royalty estimated at approximately $400 million to $570 million cumulatively over the mine's operating life. |
| • | Regional economic impacts: Within the Northwest Arctic Borough ("NWAB"), Arctic mine construction is expected to support an average of approximately 160 regional jobs and cumulative wages of approximately $50 million, and mine operations are expected to support approximately 160 regional jobs and approximately $20 million in annual wages across the 13-year mine life. |
| • | State and local government revenue: Arctic production is expected to generate approximately $31.3 million in annual Alaska state taxes and fees, including Alaska Mining License Tax and Alaska Corporate Net Income Tax. Ambler Metals expects to negotiate a payment-in-lieu-of-tax agreement with the NWAB, consistent with the existing Red Dog Mine framework, which currently provides approximately 80% of total Borough revenue. |
| • | Cost-of-living benefits for Alaska Native communities: Construction of the Ambler Access Project road, together with spur road connections, is estimated to deliver annual transportation cost savings of up to approximately $3.4 million across the Upper Kobuk and Koyukuk River communities of Ambler, Kobuk, Shungnak, Alatna, and Allakaket under a year-round gravel spur scenario. The MRG study estimates that surface access could reduce heating fuel transportation costs by approximately 70% per gallon and reduce material transportation costs on a typical single-family home in the Upper Kobuk region by approximately $287,000, a reduction of nearly 40% in total construction costs. |
