Technical Disclosure

The Technical Report was led by Ausenco, with contributions from Global Mineral Resource Services, Mining Plus and F. Wright Consulting.

The reader is advised that the PEA summarized in this press release is preliminary in nature and is intended to provide an initial, high-level review of the project's economic potential and design options. The PEA replaces and supersedes the Company's previous 2017 Feasibility Study on the project. The PEA mine plan and economic model includes numerous assumptions and the use of Inferred Resources. Inferred Resources are considered to be 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. Mineral Resources that are not mineral reserves do not have demonstrated economic viability. 

Independent Qualified Person

The PEA was prepared for NorZinc by Ausenco Pty Ltd ("Ausenco") and other industry consultants, all defined as Qualified Person ("QP") under National Instrument 43-101. The QPs that have reviewed and approved the content of this press release are:

• Kevin Murray, P.Eng, Manager, Process Engineering, Ausenco
• Greg Mosher, P.Geo, Global Mineral Resource Services
