Cautionary Note Regarding Forward-Looking Statements.

Except for historical information contained in this Current Report on Form 8-K (including Exhibits 96.1, 96.2, and 99.1) this report contains forward-looking statements which involve certain risks and uncertainties that could cause actual results to differ materially from those expressed or implied. Please refer to the cautionary statements included in the TRS, filed as Exhibit 96.1, the Initial Assessment, filed as Exhibit 96.2, and the Press Release, furnished as Exhibit 99.1 to this Current Report on Form 8-K, respectively.

Cautionary Statements Regarding the TRS and the Initial Assessment

The Technical Reports included as Exhibits 96.1 and 96.2 to this Current Report on Form 8-K contain forward-looking information derived from preliminary economic assessments and conceptual development scenarios that are subject to significant uncertainty. The TRS does not represent a feasibility study and does not support a development decision. Similarly, the Initial Assessment contract areas is not a declaration of mineral reserves and is not sufficient to determine the economic viability of a mining project. In addition, such Initial Assessment reports inferred mineral resources, which have a high degree of uncertainty as to their existence and to whether they can be economically or legally commercialized, under the Securities and Exchange Commission rules may not form the basis of an economic analysis and for which you cannot assume any part thereof will ever be upgraded to a higher category. Until mineral deposits are actually mined and processed, mineral resources and mineral reserves must be considered as estimates only. The estimates, projections, and analyses contained in the Technical Reports are based on numerous assumptions, including those related to recovery methods, costs, infrastructure, financing, regulatory approvals, and market conditions, many of which are beyond the Company’s control. Actual results may differ materially from those presented. Investors are cautioned not to place undue reliance on these Technical Reports and are encouraged to review the full summaries and underlying assumptions, which are filed as Exhibits 96.1 and 96.2 to this Current Report on Form 8-K.
