EXPLANATORY NOTE

This Amendment No. 1 (the “Amendment”) on Form 40-F/A to the Annual Report on Form 40-F of Titan Mining Corporation (the “Registrant”) for the year ended December 31, 2025 amends the Registrant’s original Annual Report on Form 40-F (the “Original Form 40-F”) that was initially filed with the U.S. Securities and Exchange Commission (the “SEC”) on March 19, 2026. This Amendment is being filed to file consents from certain qualified persons, which were inadvertently omitted in the Original Form 40-F.

In addition, as required by Rule 12b-15 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), new certifications by the Registrant’s Principal Executive Officer and Principal Financial Officer are filed herewith as exhibits to this Amendment, in the Exhibit List attached hereto, pursuant to Rule 13a-14(a) or 15d-14(a) of the Exchange Act. Because no financial statements have been included in this Amendment and this Amendment does not contain or amend any disclosure with respect to the Registrant’s disclosure controls and procedures as defined in Rule 13a-15(e) or 15d-15(e) of the Exchange Act or the Registrant’s internal control over financial reporting as defined in Rule 13a-15(f) or 15d-15(f) of the Exchange Act, paragraphs 3, 4 and 5 of the certifications have been omitted. The Registrant is also not including new certifications under Section 1350 of Chapter 63 of Title 18 of the United States Code (18 U.S.C. 1350) (Section 906 of the Sarbanes-Oxley Act of 2002), as no financial statements are being filed with this Amendment.

Other than as expressly set forth herein, this Amendment does not, and does not purport to, amend, update or restate the information in the Original Form 40-F or reflect any events that have occurred after the Original Form 40-F was made. Information not affected by this Amendment remains unchanged and reflects the disclosures made at the time at which the Original Form 40-F was made. No changes have been made to the financial statements of the Registrant as contained in the Original Form 40-F. Accordingly, this Amendment should be read together with the Original Form 40-F and the Registrant’s other filings with the SEC.
