(the “Company,” “we,” “us” or “our”) is filing this Amendment No. 1 on Form 10-K/A (this “Amendment No. 1”) to amend its Annual Report on Form 10-K for the fiscal year ended December 31, 2025, originally filed with the Securities and Exchange Commission (“SEC”) on March 31, 2026 (the “Original Filing”). Capitalized terms not otherwise defined in this Amendment No. 1 shall have the same meanings assigned to such terms in the Original Filing. We are filing this Amendment No. 1 in response to a comment letter from the SEC, dated June 9, 2026, in connection with its review of the Original Filing. The sole purpose of this Amendment No. 1 is to amend and restate in its entirety the disclosure in Part I, Item 2, “Properties,” to revise the disclosure regarding our mineral exploration projects to (a) clearly distinguish between material and non-material properties and provide the information required by Items 1303 and 1304 of Regulation S-K and (b) include disclosure regarding our exploration program internal controls as required by Item 1305 of Regulation S-K. As required by Rule 12b-15 under the Exchange Act, a new certification by the Company’s principal executive officer and principal financial officer are filed herewith as Exhibit 31.2 to this Amendment No. 1 pursuant to Rule 13a-14(a) or 15d-14(a) of the Exchange Act. As no financial statements have been included in this Amendment No. 1 and this Amendment No. 1 does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4, and 5 of the certifications have been omitted. Additionally, because this Amendment No. 1 does not include financial statements, the Company is not including certifications pursuant to Section 906 of the Sarbanes-Oxley Act of 2002. Except as described above, this Amendment No. 1 does not modify or update disclosure in, or exhibits to, the Original Filing. Furthermore, this Amendment No. 1 does not change any previously reported financial results, nor does it reflect events occurring after the date of the Original Filing. As such, information not affected by this Amendment No. 1 remains unchanged and reflects the disclosures made at the time the Original Filing was filed. Accordingly, this Amendment No. 1 should be read in conjunction with the Original Filing and other filings of the Company with the Securities and Exchange Commission.
