Although the Mesabi Trustees believe that any such forward-looking statements are based on reasonable assumptions, such statements are subject to risks and uncertainties, which could cause actual results to differ materially. &#160;Additional information concerning these and other risks and uncertainties is contained in the Trust&#8217;s filings with the Securities and Exchange Commission, including its Annual Report on Form 10-K for the fiscal year ended January 31, 2023 (filed April 24, 2023). &#160;Mesabi Trust undertakes no obligation to publicly update or revise any of the forward-looking statements made herein to reflect events or circumstances after the date hereof.</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:11pt;margin:0pt;"><span style="font-size:12pt;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:12pt;text-align:justify;background:#ffffff;margin:0pt;">In accordance with general instruction B.2 to Form 8-K, the information in this Form 8-K shall not be deemed to be &#8220;filed&#8221; for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that section.</p><p style="font-family:'Times New Roman','Times','serif';font-size:11pt;line-height:12.45pt;margin:0pt;"><span style="font-size:12.45pt;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:11pt;margin:0pt;"><span style="font-size:10pt;visibility:hidden;">&#8203;</span></p></div><div style="clear:both;display:table;margin-bottom:28.8pt;min-height:43.2pt;width:100%;"><div style="display:table-cell;vertical-align:bottom;width:100%;"><p style="font-family:'Times New Roman','Times','serif';font-size:11pt;text-align:center;margin:0pt;">1</p><p style="font-family:'Times New Roman','Times','serif';font-size:11pt;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p></div></div></div>
