2015 La Sabilia Technical Report

Cautionary Note to Investors Regarding Estimates of Indicated Resources

This Technical Report uses the term "Indicated Resources”. We advise investors that this term is not recognized by the United States Securities and Exchange Commission (the "SEC"). The estimation of Indicated Resources involves greater uncertainty as to their existence and economic feasibility than the estimation of proven and probable reserves. Mineral resources are not mineral reserves, and investors are cautioned not to assume that indicated mineral resources will be converted into reserves. Investors are urged to consider closely the disclosures in our Form 10-K and other SEC filings.
