Drilling Highlights – Arctic Project

The Company is also pleased to announce final assay results from the geotechnical and hydrological drill program completed at the Arctic poly-metallic volcanogenic massive sulphide (“VMS”) deposit (the “Arctic Project”), part of the UKMP located in the Ambler Mining District of Northwest Alaska.

The 2019 Arctic field season was comprised of advanced engineering and environmental work in support of Trilogy Metals’ feasibility study for the Arctic Project and permitting. These results will be incorporated into the study which is expected to be completed in the first half of 2020. Following its formation, the Joint Venture intends to undertake further work programs and studies for the Arctic Project.

Geochemical assay results from the geotechnical and hydrological drill program are shown below.

At a cutoff grade of 0.5% copper equivalent* the results from the new assay results at the Arctic Project are as follows:

  • AR19-164 intersected two mineralized intervals of:
    • 5.8 metres with a copper equivalent grade of 4.54% (1.45% copper, 6.24% zinc, 0.83% lead, 0.28 g/t gold and 32.20 g/t silver); and
    • 16.4 metres with a copper equivalent grade of 7.80% (5.09% copper, 4.82% zinc, 0.53% lead, 0.47 g/t gold and 47.09 g/t silver).
  • AR19-165A intersected one mineralized interval of:
    • 1.8 metres with a copper equivalent grade of 2.97% (1.66% copper, 1.87% zinc, 0.34% lead, 0.52 g/t gold and 18.87 g/t silver).
  • AR19-166 intersected five mineralized intervals of:
    • 5.1 metres with a copper equivalent grade of 6.70% (2.95% copper, 6.22% zinc, 1.47% lead, 0.75 g/t gold and 51.07 g/t silver);
    • 9.5 metres with a copper equivalent grade of 6.74% (4.12% copper, 4.78% zinc, 0.46% lead, 0.48 g/t gold and 40.61 g/t silver);
    • 1.6 metres with a copper equivalent grade of 7.84% (2.71% copper, 10.13% zinc, 2.02% lead, 0.25 g/t gold and 56.36 g/t silver);
    • 6.5 metres with a copper equivalent grade of 3.22% (1.68% copper, 2.12% zinc, 0.41% lead, 0.47 g/t gold and 35.65 g/t silver); and
    • 8.6 metres with a copper equivalent grade of 7.51% (3.62% copper, 6.81% zinc, 0.84% lead, 0.87 g/t gold and 56.00 g/t silver).
  • AR19-167 intersected one mineralized interval of:
    • 3.0 metres with a copper equivalent grade of 3.63% (2.40% copper, 2.60% zinc, 0.10% lead, 0.10 g/t gold and 16.92 g/t silver).
  • AR19-169 intersected one mineralized interval of:
    • 14.4 metres with a copper equivalent grade of 3.70% (2.20% copper, 2.61% zinc, 0.33% lead, 0.30 g/t gold and 24.20 g/t silver).
  • AR19-170 intersected two mineralized intervals of:
    • 13.7 metres with a copper equivalent grade of 6.24% (3.36% copper, 5.52% zinc, 0.74% lead, 0.33 g/t gold and 39.19 g/t silver); and
    • 7.1 metres with a copper equivalent grade of 7.17% (5.27% copper, 2.57% zinc, 0.02% lead, 0.91 g/t gold and 38.75 g/t silver).
  • AR19-171 intersected one mineralized interval of:
    • 16.6 metres with a copper equivalent grade of 6.30% (3.69% copper, 4.24% zinc, 0.85% lead, 0.45 g/t gold and 51.14 g/t silver).
  • AR19-172 intersected one mineralized interval of:
    • 16.1 metres with a copper equivalent grade of 1.71% (1.07% copper, 1.15% zinc, 0.18% lead, 0.10 g/t gold and 9.08 g/t silver).

* Assumptions used for the copper equivalent calculation were metal prices in USD of $2.90/lb copper, $1.10/lb zinc, $0.90/lb lead, $1,250/oz gold, and $18/oz silver. The following equation was used to calculate copper equivalence: CuEq = Copper (%) + (Zinc (%) x 0.379) +(Lead (%) x 0.310) + (Gold (g/t) x 0.629) + (Silver (g/t) x 0.009).

James Gowans, Interim President and CEO of Trilogy Metals commented, “The latest drilling results continue to demonstrate that not only is the Arctic Project one of the highest grade known polymetallic base metal projects in the world, but it is also incredibly consistent along strike and dip regardless of where you drill at the project. We believe there is the possibility of other “Arctic like” deposits being discovered within the 100-kilometer long Ambler Mining District. Further drilling by the Joint Venture is intended to test targets across the UKMP.”

At the Arctic Project and as described above, the Company drilled ten holes comprising 2,422 meters of which eight holes were sampled and sent off for assay analysis. Hole AR19-165 was lost due to technical drilling issues and hole AR19-0168 did not intersect base metal mineralization as it tested the south highwall and did not target the mineralized zones. Drilling at Arctic during the 2019 field season was carried out to support mine design and the collection of further geotechnical and hydrological information.The material will be used for additional metallurgical test work in the future.

The VMS-style mineralization at Arctic was discovered by Bear Creek Mining Company in 1965 and is exposed on the east side of the north trending Arctic Ridge. The rock units exposed are typical of the Ambler Schist sequence and include quartz +/- feldspar and chlorite +/- talc schist, graphitic and graphitic quartz schist, and aphanitic and porphyritic meta-rhyolite units.Massive and semi-massive sulphide mineralization, consisting of chalcopyrite, sphalerite, galena, and tetrahedrite/tennantite, occurs in 0.1 metre to 26-metre bands generally at a contact between graphitic and quartz-chlorite +/- talc schist.

Results for the 2019 drill program at Arctic are presented in Table 1 at a cutoff grade of 0.5% copper equivalent.All the intersected widths are close to normal to stratigraphy and therefore can be considered to be true widths.Table 2 shows the drill hole locations.Figure 1 shows the location of the drill holes on a plan map and Figure 2 shows a cross-section through drill holes AR19-0164, and AR19-0166. Figure 3 shows a cross-section through drill holes AR19-0169, AR19-0170 and AR19-0171.

* Assumptions used in USD for the copper equivalent calculation were metal prices of $2.90/lb copper, $1.10/lb zinc, $0.90/lb lead, $1,250/oz gold, and $18/oz silver. The following equation was used to calculate copper equivalence: CuEq = Copper (%) + (Zinc (%) x 0.379) +(Lead (%) x 0.310) + (Gold (g/t) x 0.629) + (Silver (g/t) x 0.009).

QA/QC Program

The drill program, sampling protocol, and data verification were managed by qualified persons employed by the Company. Diamond drill holes were typically collared and drilled to depth HQ for the Arctic holes, except for holes AR19-0166 and AR19-170, which were collared PQ. Samples were collected using a 0.13-metre minimum length, a 2.5-metre maximum length and a 1.36-metre average sample length. Drill core recovery averaged 97% for Arctic core. Three quality control samples (one blank, one standard and one duplicate) were inserted into each batch of 20 samples. The drill core was sawn, with half sent to ALS Minerals in Fairbanks for sample preparation and the sample pulps forwarded to ALS's North Vancouver facility for analysis. ALS Minerals is an independent facility certified as ISO 9001:2008 and accredited to ISO / IEC 17025:2005 from the Standards Council of Canada. The assay and QA/QC results were reviewed by a third-party consultant, GeoSpark Consulting Inc. of Nanaimo, British Columbia, and in their opinion shows overall good quality for silver, copper, lead, and gold analyses. The Company submitted 5% of the mineralized assay intervals to an independent check assay lab.

Arctic Feasibility Study

Trilogy Metals continues to progress its Arctic feasibility study which is being prepared by Ausenco Engineering Canada Inc. and John Wood Group PLC based on drill results and studies completed prior to formation of the Joint Venture. Trilogy Metals expects to release its Arctic feasibility study by the end of first half 2020, in advance of further work programs and studies planned to be completed by the Joint Venture.

Ambler Mining District Industrial Access Project (“AMDIAP”)

On October 29, 2019 the comment period closed for the AMDIAP Draft Environmental Impact

Statement (“EIS”). The Bureau of Land Management (“BLM”), which is the lead agency, is now incorporating the comments into the final EIS.
