Cautionary Note Regarding Forward-Looking Statements

It should be noted that Luca declared commercial production at Campo Morado prior to completing a

feasibility study of mineral reserves demonstrating economic and technical viability. Accordingly, readers

should be cautioned that Luca's production decision has been made without a comprehensive feasibility

study of established reserves such that there is greater risk and uncertainty as to future economic results

from the Campo Morado mine and a higher technical risk of failure than would be the case if a feasibility

study were completed and relied upon to make a production decision. Luca has completed a preliminary

economic assessment ("PEA") mining study on the Campo Morado mine that provides a conceptual life of

mine plan and a preliminary economic analysis based on the previously identified mineral resources (see

news releases dated November 8, 2017, and April 4, 2018).

Project and Campo Morado will continue to provide information to guide exploration program plans; the
