The 2019 drill program at Arctic included 10 holes aimed at collecting information for a feasibility study for developing a mine at this high-grade copper-zinc-lead-gold-silver deposit in Alaska's Ambler Mining District.

Trilogy Metals Inc. Jan. 16 reported that its geotechnical and hydrological drill program at the Arctic mine project continued to show the consistency and high grades of the copper-zinc-lead-gold-silver mineralization within this volcanogenic massive sulfide (VMS) deposit in Northwest Alaska.

The 2019 field program at Arctic involved advanced engineering and environmental work in support of Trilogy Metals' feasibility study for the Arctic Project and permitting.

In December, South32 exercised its option to acquire a 50 percent interest in a joint venture company that will own the Upper Kobuk Mineral Projects (UKMP), which includes Arctic.

More information on this joint venture and UKMP can be read at South32 agrees to landmark JV in Alaska in the Dec. 20 edition of North of 60 Mining News.

Following its formation, the UKMP joint venture intends to undertake further work programs and studies for Arctic and the feasibility study for developing a mine there is slated for completion in the first half of 2020.

The 2019 program at Arctic involved 2,422 meters of drilling in ten holes. Highlights from this drilling include:

• AR19-164 cut two mineralized intervals – 5.8 meters averaging 1.45 percent copper, 6.24 percent zinc, 0.83 percent lead, 0.28 grams per metric ton gold and 32.2 g/t silver; and 16.4 meters averaging 5.09 percent copper, 4.82 percent zinc, 0.53 percent lead, 0.47 g/t gold and 47.09 g/t silver.

• AR19-166 cut five mineralized intervals – 5.1 meters averaging 2.95 percent copper, 6.22 percent zinc, 1.47 percent lead, 0.75 g/t gold and 51.07 g/t silver; 9.5 meters averaging 4.12 percent copper, 4.78 percent zinc, 0.46 percent lead, 0.48 g/t gold and 40.61 g/t silver; 1.6 meters averaging 2.71 percent copper, 10.13 percent zinc, 2.02 percent lead, 0.25 g/t gold and 56.36 g/t silver; 6.5 meters averaging 1.68 percent copper, 2.12 percent zinc, 0.41 percent lead, 0.47 g/t gold and 35.65 g/t silver; and 8.6 meters averaging 3.62 percent copper, 6.81 percent zinc, 0.84 percent lead, 0.87 g/t gold and 56 g/t silver.

• AR19-170 cut two mineralized intervals – 13.7 meters averaging 3.36 percent copper, 5.52 percent zinc, 0.74 percent lead, 0.33 g/t gold and 39.19 g/t silver; and 7.1 meters averaging 5.27 percent copper, 2.57 percent zinc, 0.02 percent lead, 0.91 g/t gold and 38.75 g/t silver.

• AR19-171 cut one mineralized interval – 16.6 meters averaging 3.69 percent copper, 4.24 percent zinc, 0.85 percent lead, 0.45 g/t gold and 51.14 g/t silver.

"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," said James Gowans, interim president and CEO, Trilogy Metals. "We believe there is the possibility of other 'Arctic-like' deposits being discovered within the 100-kilometer- (62 miles) long Ambler Mining District. Further drilling by the joint venture is intended to test targets across the UKMP."
