Trilogy Metals to Complete Pre-feasibility Study on High-Grade Arctic Deposit







VANCOUVER, March 20, 2017 /CNW/ – Trilogy Metals Inc. (TSX, NYSE-MKT: TMQ) (“Trilogy Metals” or “the Company”) is pleased to announce that it intends to undertake a pre-feasibility study (“PFS”) on the high-grade Arctic deposit located in northwest Alaska.  The PFS will be supported by information collected during the 2015 and 2016 field seasons as well as additional information to be collected during the 2017 summer field program.  A budget totaling $7.1 million for fiscal 2017 has received board approval, and will focus mainly on the Arctic Project PFS with an anticipated completion date of Q1 2018.  The Arctic Project is a very high-grade polymetallic volcanogenic massive sulphide (“VMS”) deposit, hosting copper-zinc-lead-gold-silver mineralization with an average grade of 6% copper equivalent which has the potential to be mined in an open-pit.

The PFS will incorporate all of the information collected over the past two years of in-fill drilling and related studies, including: an updated resource model; geotechnical pit-slope stability studies; hydrology; waste rock characterization and metallurgy (all of which are now completed, or will be shortly).  The remaining field work to be completed during this field season will cover studies related to determining the placement of all site facilities, including: the ore processing facility (crushing and milling); the waste rock and tailings disposal area(s); water storage ponds and supporting road infrastructure.  In addition, on-going environmental data collection will continue – sufficient to be used to support a PFS level of study.  Site work will include geotechnical drilling, hydrology installations, and test pits for site facility locations and mine design, and geophysical ground surveys to evaluate ground conditions.  A…
