About Trilogy Metals Inc.

Trilogy Metals is a metal exploration company focused on exploring and developing the Ambler mining district, located in northwestern Alaska. It is one of the richest and most prospective known copper-dominant districts, located in one of the safest geopolitical jurisdictions in the world. It hosts world-class polymetallic VMS (volcanogenic massive sulphide) deposits that contain copper, zinc, lead, gold and silver, and carbonate replacement deposits, which have been found to host high-grade copper mineralization. Exploration efforts have been focused on two deposits in the Ambler mining district: the Arctic VMS deposit and the Bornite carbonate replacement deposit.
