Notes:

The 2017 PEA supersedes all previous NI 43-101 Technical Reports for the Carmacks Project. The PEA was prepared in accordance with the requirements of NI 43-101 by JDS Energy & Mining, Inc. of Vancouver, British Columbia, with geology and mineral resource estimation by Arseneau Consulting Services Inc. of Vancouver, British Columbia, metallurgy by Dreisinger Consulting Inc. of Vancouver, British Columbia, and mining method by Independent Mining Consultants Inc. of Tucson, Arizona. Geotechnical, water management and water quality studies were conducted by Golder Associates Ltd. of Vancouver, British Columbia. Environmental data were collected by Access Consulting Group of Whitehorse, Yukon.

The 2017 PEA is preliminary in nature and includes inferred mineral resources that are considered too speculative geologically to have 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. Refer to the 2017 PEA, filed on www.sedar.com under the Company's profile on 9 February 2017, for a discussion of the applicable qualifications and assumptions and the impact of the results of the previous studies on the Carmacks Project.
