VANCOUVER, BC, March 17, 2022 /PRNewswire/ - Trilogy Metals Inc. (TSX: TMQ) (NYSE: TMQ) ("Trilogy" or the "Company") is pleased to announce the fourth set of drilling results from the 2021 summer field season at the Arctic Project, part of the Upper Kobuk Mineral Projects ("UKMP") located in Northwestern Alaska managed by Ambler Metals LLC ("Ambler Metals"), the joint venture operating company equally owned by wholly owned subsidiaries of Trilogy and South32 Limited (ASX: S32) (LSE: S32) (JSE: S32) (ADR: SOUHY) ("South32").
The 2021 Arctic drill program included 4,131 meters of diamond drilling, comprising 18 holes, that were designed to convert part of the resources from the Indicated category to the Measured category, and provide material for metallurgical testing and geotechnical information. The assay results detailed here are for additional infill/metallurgical drill holes from the 2021 summer field season.
Highlights from the latest metallurgical/infill drill holes from the 2021 drill program
Based on a cut-off grade of 0.5% copper equivalent, significant zones of high-grade copper, zinc, lead, gold, and silver mineralization were intersected, including:
The Company is also providing an update in the progress of the Ambler Access Project ("AAP"). On February 22, 2022, the United States Department of the Interior ("DOI") filed a motion to remand the Final Environmental Impact Statement ("FEIS") and suspend the right-of-way permits issued to the Alaska Industrial Development and Export Authority ("AIDEA") for the AAP. The DOI has stated that the suspension of the road permits will allow it to carry out additional supplemental work on the FEIS. Please see Trilogy's press release dated February 23, 2022 for more information.
Last week, Ambler Metals, jointly with NANA Regional Corporation ("NANA"), filed a motion with the court requesting a two-week extension of time to file its responses to the DOI's motion for voluntary remand. This filing will allow Ambler Metals, NANA, the State of Alaska and AIDEA, as intervening defendants, time to confer with the DOI and work toward finding a workable arrangement to manage the remand process. The Company intends to provide an update on the AAP permitting situation when it has more clarity on the scope and timing of the proposed supplemental work.
Tony Giardini, President and CEO of Trilogy, commented, "These drilling results continue to confirm that the Arctic Project has some of the most compelling copper grades in the mining industry. The planned 2022 summer field season at the UKMP currently includes a 10,000-meter drilling campaign focused on further infill drilling at Arctic and on exploring priority prospects and other targets within our expansive land package. I also want to reaffirm our commitment with South32 to advance the UKMP while balancing the timeline for the State of Alaska to provide infrastructure access to the Ambler Mining District."
Richard Gosse, Trilogy's Vice President, Exploration stated, "Again, as with some of the previously announced infill holes, the drill core gives us a glimpse of the scale of this remarkable world-class volcanogenic massive sulphide ("VMS") deposit. Hole AR21-0181, with polymetallic massive sulphides grading 3% to 8% copper equivalent in six intervals with an accumulated true thickness of about 78 metres (255 feet) over a core length of 110 metres (360 feet), is outstanding but not unexpected. Along strike from Arctic, VMS-like prospects, airborne EM targets and geochemical anomalies occur for over the 97-kilometre (60-mile) Ambler Belt, most of which is held by Ambler Metals. We look forward to announcing the results of last year's exploration activities in the belt as well as the remaining drill results from Arctic in the coming weeks."
On November 22, 2021, the Company released the assay results for two geotechnical drill holes AR21-0173 and AR21-0175 that intersected high-grade mineralization beyond the currently designed pit at Arctic. Subsequently on November 29, 2021, the Company released additional drilling results from two infill/metallurgical holes drilled early in the 2021 field season. Of note is drill hole AR21-0176 which intersected 19.91 meters of almost 12% copper equivalent. On January 25, 2022, the Company released the results for two additional metallurgical/infill drill holes from Arctic. For more information on these drilling results, please visit the Company's website at https://trilogymetals.com/news-and-media/news/.
The results of the remaining eight holes are expected to be announced over the next few weeks.
These latest drilling results from the 2021 program contain mineralized intervals consistent with previous drilling conducted within the resource area on the property. Significant mineralized intervals of high-grade mineralization at a cut-off of 0.5% copper equivalent are reported in Table 1. The locations of the holes are shown in Figure 1 and Table 2.
Of the 18 holes drilled at Arctic last summer, eight holes were for the geotechnical program. The 10 remaining drill holes were part of the infill/metallurgical program, with three of the 10 drill holes also being used for the hydrology program.
