Positive Feasibility Study Results Alaska Arctic Project

VANCOUVER - Trilogy Metals Inc. reported positive results of its Feasibility Study (FS) for the Arctic Copper-Zinc-Lead-Silver-Gold Project in the Ambler mining district of Northwestern Alaska.  The Arctic Project is held by Ambler Metals LLC, the joint venture operating company equally owned by Trilogy and South32 Limited.  

The FS describes the technical and economic viability of establishing a conventional open-pit copper-zinc-lead-silver-gold mine-and-mill complex for a 10,000 tonne-per-day operation for a minimum 12-year mine life.

Tony Giardini, President and Chief Executive Officer, said, "Arctic is a special project due to its unique high-grade polymetallic nature.  The only other time that I've seen a project of this quality where the grades were similar was in an underground mining scenario.  However, Arctic is  mineable in an open pit scenario. I also want to highlight that Arctic contains a significant amount of gold and silver. At current spot metal prices, the precious metals output represents almost 20% of its revenue. The annual gold equivalent (gold and silver) payable output is about 80,000 ounces per year."

Jim Gowans, Director, said, "Arctic is located in the extremely prospective Ambler Mining District, in a mining friendly jurisdiction, in Alaska, where solid environmental regulations and a balanced permitting process is established. I am also very pleased that we are working with NANA Regional Corporation, Inc., who understand mining and have an established record of working at the Red Dog Mine."

The FS forecasts an average annual payable production to be more than 155 million pounds of copper, 192 million pounds of zinc, 32 million pounds of lead, 32,165 ounces of gold and 3.4 million ounces of silver. Total life of mine 12-year production is projected at 1.9 billion pounds of copper, 2.3 billion pounds of zinc, 388 million pounds of lead, 386 thousand ounces of gold and 40.6 million ounces of silver.
