The reader is advised that the preliminary economic assessment summarized in this press release is only intended to provide an initial, high-level review of the project. The PEA mine plan and economic model include the use of inferred mineral resources which 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 preliminary economic assessment will be realized.

The PEA mine plan and economic model include the use of inferred resources which are considered to be too speculative to be used in an economic analysis except as permitted by NI 43-101 for use in PEA's. There is no guarantee that inferred resources can be converted to indicated or measured resources and, as such, there is no guarantee that the project economics described herein will be achieved. Mineral resources that are not mineral reserves do not have demonstrated economic viability.
