Vista Gold Corp. Qualified Person: All scientific and technical information contained herein has been prepared by, or under the supervision of, John Rozelle, Vista’s Senior Vice President, a Qualified Person as defined by subpart 1300 of Regulation S-K (“SK 1300”) and Canadian National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”).
Cautionary Note Concerning Estimates of Proven and Probable Mineral Reserves and Measured, Indicated and Inferred Resources: The estimates of mineral reserves shown in this website have been prepared in accordance with the definition standards on mineral reserves of SK 1300 and NI 43-101 and the Canadian Institute of Mining, Metallurgy and Petroleum referred to in NI 43-101. Both sets of reporting standards have similar goals in terms of conveying an appropriate level of confidence in the disclosures being reported, but the standards embody slightly different approaches and definitions. In our public filings in the U.S. and Canada and in certain other announcements not filed with the SEC, we disclose proven and probable reserves and measured, indicated and inferred resources, each as defined in S-K 1300 and NI 43-101. As currently reported, there are no material differences in our disclosed proven and probable reserves and measured, indicated and inferred resource under each of S-K 1300 and NI 43-101. The estimation of measured resources and indicated resources involve greater uncertainty as to their existence and economic feasibility than the estimation of proven and probable reserves, and therefore investors are cautioned not to assume that all or any part of measured or indicated resources will ever be converted into S-K 1300-compliant or NI 43-101-compliant reserves. The estimation of inferred resources involves far greater uncertainty as to their existence and economic viability than the estimation of other categories of resources, and therefore it cannot be assumed that all or any part of inferred resources will ever be upgraded to a higher category. Therefore, investors are cautioned not to assume that all or any part of inferred resources exist, or that they can be mined legally or economically.
