The Company would like to clarify that the mine plan (process plant feed) includes approximately 77% Indicated Mineral Resources and 23% Inferred Mineral Resources. The PEA is preliminary in nature, and it includes Inferred Mineral Resources that are considered too speculative geologically to have the economic considerations applied that would enable them to be classified as Mineral Reserves, and there is no certainty that the PEA will be realized. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.
