Economics

Carmacks Project Economics are based on the 2017 Preliminary Economic Assessment filed on www.sedar.com on 9 February 2017. The new technical report in progress is based on an agitated tank leach process plan and is substantially different than the previous heap leach plan. The new mine and leach plan includes the recovery of both copper and gold and silver.

Financial Analysis

The 2017 Preliminary Economic Assessment is based on a copper price of US$2.50/lb, US$1300/z gold and US$17.50/oz silver.

Notes: The 2017 Preliminary Economic Assessment (PEA) changes the leach plan for oxide copper mineralization and provides for gold and silver leach following completion of the copper leach in agitated tank leach. The PEA evaluation does not include sulphide mineral resources. The PEA was prepared by JDS Energy and Mining In.c with Independent Qualified Persons; Giles Arseneau for Mineral Resource estimation, Golder Associates Ltd. for geotechnical, Independent Mining Consultants for mining plan and Dr. David Dreisinger for metallurgical and processing. The new PEA is based on the mineral resources for zones 1,4 and 7 and do not include the new mineral resources filed March 10, 2016. The oxide mineral resource forming the basis of the economic assessment includes Inferred 90,000 tonnes comprising approximately 0.75% of all mineral resources. There is no certainty that additional drilling will confirm the conversion of Inferred resources to Measured and Indicated categories.

Notes: The technical report entitled "Preliminary Economic Assessment of Copper, Gold, and Silver Recovery" (filed on www.sedar.com on 9 February 2017) is preliminary in nature and includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves and there is no certainty that the PEA will be realized.
