Cautionary note to U.S. Investors concerning estimates of mineral reserves and mineral resources

Skeena’s mineral reserves and mineral resources included or incorporated by reference herein have been estimated in

accordance with National Instrument 43 -101 – Standards of Disclosure for Mineral Projects (“NI 43-101”) as required by

Canadian securities regulatory authorities, which differ from the requirements o f U.S. securities laws. The terms “mineral

reserve”, “proven mineral reserve”, “probable mineral reserve”, “mineral resource”, “measured mineral resource”,

“indicated mineral resource” and “inferred mineral resource” are Canadian mining terms as defined in accordance with NI

43-101 and the Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) “CIM Definition Standards – For Mineral

Resources and Mineral Reserves” adopted by the CIM Council (as amended, the “CIM Definition Standards”). These

standards differ significantly from the mineral property disclosure requirements of the U.S. Securities and Exchange

Commission in Regulation S-K Subpart 1300 (the “SEC Modernization Rules”). Skeena is not currently subject to the SEC

Modernization Rules. Accordi ngly, Skeena’s disclosure of mineralization and other technical information may differ

significantly from the information that would be disclosed had Skeena prepared the information under the standards

adopted under the SEC Modernization Rules.

In addition, investors are cautioned not to assume that any part or all of Skeena’s mineral resources constitute or will be

converted into reserves. These terms have a great amount of uncertainty as to their economic and legal feasibility.

Accordingly, investors are cautioned not to assume that any “measured”, “indicated”, or “inferred” mineral resources that

Skeena reports are or will be economically or legally mineable. Further, “inferred mineral resources” have a great amount

of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed

that all or any part of an “inferred mineral resource” will ever be upgraded to a higher category. Under Canadian securities

laws, estimates of “inferred mineral resources” may not form the basis of feasibility or prefeasibility studies, except in rare

cases where permitted under NI 43-101.

For these reasons, the mineral reserve and mineral resource estimates and related information presented herein may not

be comparable to similar information made public by U.S. companies subject to the reporting and disclosure requirements

under the U.S. federal securities laws and the rules and regulations thereunder.
