Note on Assumptions

The PEA results are based on important assumptions made by the Qualified Persons who prepared the PEA. These assumptions, including those mentioned above, and the justifications for them, are described in the PEA.

The PEA is preliminary in nature and includes inferred mineral resources that 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 PEA will be realized.
