Cautionary and Forward-Looking Statements

Readers are cautioned that the Barry Open Pit PEA is preliminary in nature and includes inferred mineral resources that are too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves. There is no certainty that the results, assumptions or estimates in the Barry Open Pit PEA will be realized. Mineral resources are not mineral reserves and do not have demonstrated economic viability.
