Cautionary Note Regarding Production Decisions and 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 fea sibility 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).

Furthermore, Luca intends to declare commercial production at t he Tahuehueto gold, silver mine

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

technical risk of failure than would be the case if a feasibility study were completed and relied upon

silver mine (see news releases dated April 26, 2022).
