Cautionary Statement

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 mine plan and economic model includes numerous assumptions and the use of

Inferred Resources. Inferred Resources are considered to be too speculative geol ogically 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.

Certain statements contained in this press release constitute forward -looking information under the

provisions of Canadian securities laws . Such statements are necessarily based upon a number of

beliefs, assumptions, and opinions of management on the date the statements are made and are

subject to numerous risks and uncertainties that could cause actual results and future events to differ

materially from those anticipated or projected. The Company undertakes no obligation to update

these forward-looking statements in the event that management's beliefs, estimates or opinions, or

other factors should change, except as required by law.

Neither the TSX Venture Exchange nor its Regulation Services Provider (as that term is defined in the
