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 inclu des 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.
