Forward-Looking Information

Investors should be aware that the U.S. EXIM Letter of Interest ("LOI") is non-binding and conditional, and does not represent a financing commitment. A funding commitment, if any, is conditional upon successfully completing the due diligence and underwriting process, which may not be completed on the expected timeline, or at all. If the Company's application is approved, there can be no assurance that the U.S. EXIM financing will be for the full amount indicated in the LOI or the increased amount requested in the application, or that the approved U.S. EXIM financing will be sufficient for the Company to commence construction of the Project. Further, release of funding under any such commitment would be subject to the satisfaction of certain conditions and covenants by the Company. 

Investors should be aware that the Company has not entered into any definitive agreement with respect to a royalty, streaming or guarantee and may not be able to enter into such agreement on the anticipated terms and timeline, or at all. In addition, the outcomes from such agreement, when entered into, may not be sufficient to satisfy the aggregate obligations of the Company to provide construction phase financial assurance under applicable federal and state law prior to commencing construction. Securing the financial assurance does not guarantee the Company will receive the U.S. Forest Service ("USFS") notice to proceed under the approved plan of operation and consummating the royalty financing may not satisfy the financial assurance conditions of various federal and state permits required to commence construction. 

Investors should be aware that state regulators are not bound by permitting schedules and anticipated timelines may be delayed materially or not be satisfied.
