Upper Kobuk Mineral Projects Has Completed Second Round Of Drilling

VANCOUVER - Trilogy Metals Inc. reported second set of drilling results from the 2022 summer field season at the Upper Kobuk Mineral Projects (UKMP) located in northwestern Alaska. In addition, the Company is providing an update on the Ambler Access Project – the proposed 211-mile, industrial-use-only road from the UKMP to the Dalton Highway that will enable advancing exploration and development at the Ambler Mining District.

The UKMP includes the Arctic (volcanogenic massive sulphide, or "VMS") deposit (Arctic), the Bornite (carbonate-hosted copper, or "CHC") deposit (Bornite), and prospective mining claims in the surrounding area. The drill program was completed by Ambler Metals LLC (Ambler Metals), the joint venture operating company.

The 2022 field program included 10,738 meters of diamond drilling, of which 8,376 meters was drilled at Arctic, the most ever drilled at Arctic in a single field season, while the remainder of the meterage was used on regional targets in the Ambler VMS Belt and near Bornite. The 2022 field program prioritized advancing Arctic with additional infill drilling to further improve the confidence in the mineral resource and for geotechnical studies to further de-risk the project.

An additional 10 holes comprising eight infill and two geotechnical were completed for the second set. The infill holes are from two areas of the Arctic deposit – three holes from the northern edge of the Arctic deposit and five holes from the eastern part of the deposit. Significant intersections of high-grade copper, zinc, lead, gold, and silver mineralization include: Hole AR22-0201: 6.72 meters of 3.40% copper, 3.26% zinc, 0.48% lead, 0.358 g/t gold and 32.66 g/t silver for a copper equivalent grade of 5.27%; Hole AR22-0204: 5.03 meters of 3.57% copper, 4.46% zinc, 0.69% lead, 0.351 g/t gold and 33.05 g/t silver for a copper equivalent grade of 5.96%; Hole AR22-0213: 4.66 meters of 3.22% copper, 3.22% zinc, 0.28% lead, 0.194 g/t gold and 28.90 g/t silver for a copper equivalent grade of 4.87%; Hole AR22-0215: 8.24 meters of 3.19% copper, 10.04% zinc, 2.50% lead, 0.705 g/t gold and 72.35 g/t silver for a copper equivalent grade of 8.81%, and 19.87 meters of 2.67% copper, 1.72% zinc, 0.22% lead, 0.427 g/t gold and 38.34 g/t silver for a copper equivalent grade of 3.99%; Hole AR22-0232: 3.03 meters of 4.70% copper, 5.47% zinc, 1.35% lead, 0.636 g/t gold and 56.67 g/t silver for a copper equivalent grade of 8.07%; and Hole AR22-0237: 10.00 meters of 3.73% copper, 2.54% zinc, 0.42% lead, 0.067 g/t gold and 47.95 g/t silver for a copper equivalent grade of 5.66%.

Tony Giardini, President and CEO, said, "As expected, the 2022 infill drill program continues to yield high grades of copper, zinc and precious metals, demonstrating the continuity of the high-grade zones of these metals at Arctic. The assay lab is going full steam ahead as we anticipate an ongoing flow of results in the near future, not only from Arctic but also from the nearby Ambler Belt and Cosmos Hills areas."
