Trilogy Metals announces additional Arctic Project drill results

The 2021 Arctic drill programme included 4131 m of diamond drilling, comprising 18 holes, that were designed to convert a portion of the resources from the indicated category to the measured category, and provide material for metallurgical testing and geotechnical information. The results contained in this news release are from the first two infill holes that were drilled early in the 2021 field season.

On 22 November 2021, the company released the assay results for holes AR21-0173 and AR21-0175, two geotechnical drill holes that intersected high-grade mineralisation beyond the currently designed pit at Arctic.

The results of the remaining 14 holes are expected to come in over the next couple of months.

Based on a cut-off grade of 0.5% copper equivalent (CuEq), significant zones of high-grade copper (Cu), zinc (Zn), lead (Pb), gold (Au), and silver (Ag) mineralisation were intersected, including:

• AR21-0176 intersected three mineralised intervals, including:
  • 19.91 m of 6.75% Cu, 7.59% Zn, 1.68% Pb, 1.26 g/t Au and 97.13 g/t Ag for a CuEq grade of 11.76%.
  • 6.76 m of 1.55% Cu, 6.61% Zn, 1.58% Pb, 0.12 g/t Au and 20.68 g/t Ag for a CuEq grade of 4.77%.
• AR21-0174 intersected one mineralised interval of 10.12 m of 3.21% Cu, 6.14% Zn, 1.46% Pb, 0.69 g/t Au and 49.74 g/t Ag for a CuEq grade of 6.84%.

All reported intervals are thought to be close to the true width and therefore represent the actual thickness of mineralisation.

Drill hole AR21-0176, which contained 19.91 m of 11.76% CuEq (a grade thickness of 234.09% m), represents the third highest ever grade-thickness intersect out of 178 holes drilled at the Arctic Project to date.

Tony Giardini, President and CEO of Trilogy, commented: “The 2021 drilling campaign confirms that the Arctic Project has some of the highest grades of polymetallic mineralisation in the world with copper-equivalent grades frequently in the double digits. The copper-equivalent grades at Arctic rival some of the high-grade copper projects in Africa, while being in one of the most stable mining jurisdictions in the world.”

Richard Gosse, Vice President, Exploration at Trilogy, added: “These assays from the 2021 drill programme are an exciting start to the infill drill program at Arctic. Grades of almost 12% CuEq over 20 m, considered close to true width, is one of the best intervals at Arctic since the first hole was drilled in 1967. We are looking forward to seeing the results of the other 14 drill holes at Arctic as well as from the regional drill programme.”
