ITEM 9A.                                            CONTROLS AND PROCEDURES.

Evaluation of Disclosure Controls and Procedures.  The Trust maintains a system of  disclosure controls and procedures designed to ensure that information required to be disclosed by Mesabi Trust in the reports that it furnishes or files under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the rules and regulations of the Securities and Exchange Commission.  Due to the pass-through nature of the Trust, the Trust’s disclosure controls and procedures include controls and procedures designed to ensure that information required to be disclosed by Mesabi Trust is received from Cliffs Natural Resources Inc. (“Cliffs”) and its wholly-owned subsidiary,

3

Northshore Mining Company (“Northshore”).  In order to help ensure the accuracy and completeness of the information required to be disclosed in the Trust’s periodic and annual reports, the Trust employs certified public accountants, geological consultants, and attorneys.  These outside professionals advise the Trust in its review and compilation of the information in this Form 10-K and the other periodic reports filed by the Trust with the SEC.

As part of their evaluation of Mesabi Trust’s disclosure controls and procedures, the Trustees rely on quarterly shipment and royalty calculations provided by Northshore and Cliffs.  Because Northshore has declined to provide a written certification attesting to whether Northshore has established disclosure controls and procedures and internal controls sufficient to enable it to verify that the information furnished to the Trustees is accurate and complete, the Trustees also rely on (a) an annual certification from Northshore and Northshore’s parent, Cliffs Natural Resources Inc. (“Cliffs”), certifying as to the accuracy of the royalty calculations, and (b) the related due diligence review performed by the Trust’s accountants.  In addition, Mesabi Trust’s consultants review the schedule of leasehold royalties payable and shipping and sales reports provided by Northshore against production and shipment reports prepared by Eveleth Fee Office, Inc., an independent consultant to Mesabi Trust (“Eveleth Fee Office”). Eveleth Fee Office performs inspections of the Northshore mine and its pelletizing operations, observes production and shipping activities, gathers production and shipping information from Northshore and prepares monthly production and shipment reports for the Trustees. Furthermore, as part of its engagement by Mesabi Trust, Eveleth Fee Office also attends Northshore’s calibration and testing of its crude ore scales and boat loader scales which are conducted on a periodic basis.

As of the end of the period covered by this report, the Trustees carried out an evaluation of Mesabi Trust’s disclosure controls and procedures.  The Trustees have concluded that such disclosure controls and procedures are effective.

Trustees’ Report on Internal Control over Financial Reporting.  The Trustees’ Report on Internal Control over Financial Reporting is set forth on page F-2 of the Annual Report.  The attestation report of the Trust’s independent registered public accounting firm on their assessment of the Trust’s internal control over financial reporting is set forth on pages F-3 of the Annual Report.

Changes in Internal Control over Financial Reporting.  To the knowledge of the Trustees, there has been no change in the Trust’s internal control over financial reporting that occurred during the Trust’s last fiscal quarter that has materially affected, or is likely to materially affect, the Trust’s internal control over financial reporting.  The Trustees note for purposes of clarification that they have no authority over, and make no statement concerning, the internal controls of Northshore.

ITEM 9B.                                            OTHER INFORMATION.

None.

PART III

ITEM 10.                                              DIRECTORS, EXECUTIVE OFFICERS AND CORPORATE GOVERNANCE.

The Agreement of Trust dated July 18, 1961 (the “Agreement of Trust”) provides for a Corporate Trustee and four Individual Trustees (collectively, the “Trustees”).  The Trust does not have, nor does the Agreement of Trust provide for officers, a board of directors or an audit committee.  Generally, the Trustees continue in office until their resignation or removal.  Any Trustee may be removed at any time, with or without

4

cause, by the holders of two-thirds in interest of the Certificates of Beneficial Interest in the Trust (the “Trust Certificates”) then outstanding.  In the case of an Individual Trustee, a successor is appointed if the Individual Trustee dies, becomes incapable of acting or is adjudged bankrupt or insolvent.  In the case of the Corporate Trustee, a successor is appointed if a receiver of the Corporate Trustee or of its property is appointed, or if any public officer takes charge or control of the Corporate Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation.  Successor Trustees can only be appointed by the holders of a majority in interest of the Trust Certificates then outstanding.  Because such appointments are not made on a regular or periodic basis, the Trust does not have a standing nominating committee or a policy in place for the recommendation and nomination of successor Trustees.

The Trust’s activities are limited to collecting income, paying expenses and liabilities, distributing net income to the holders of Trust Certificates (the “Unitholders”) after the payment of, or provision for, such expenses and liabilities, and protecting and conserving the assets held.  Although the Trust is not required to designate an audit committee because of an exemption from Rule 10A-3 of the Securities Exchange Act of 1934, as amended, and the rules promulgated thereunder, the Trustees believe that they collectively perform the functions of an audit committee.  The Trustees have not designated an “audit committee financial expert.”  The Trustees have adopted a Code of Ethics that applies to the Trustees.  A copy of the Code of Ethics is incorporated by reference in Exhibit 14 of this Form 10-K.

To carry out the Trustees’ duties under the Agreement of Trust, the Trustees meet on a quarterly basis to discuss information and circumstances relevant to the Trust.  The Trustees also conduct telephone conferences from time to time between the quarterly meetings to address developments that require more timely attention.  The Trust held twelve meetings either in person or via teleconference in fiscal 2011.  All of the Trustees were present at all of the meetings held in fiscal 2011.

In the third quarter of each year, the Trustees’ meeting is typically conducted in connection with the Trustees’ annual inspection trip in which they personally visit and tour Northshore’s mining operations and plant facilities located near Babbitt and in Silver Bay, Minnesota, respectively.  During the inspection trip, the Trustees meet with and interview Northshore personnel with respect to Northshore’s current operations, changes in operations, mining plans, capital equipment and facilities.

Because Mesabi Trustees are appointed until they resign or are removed, at the time of nomination the Trustees believe that it is necessary for each Trustee to possess many qualities and skills. The present Trustees of Mesabi Trust principal occupations and directorships held with other public corporations during the past five years, or longer as material, their ages and the year first elected as a Trustee, are set forth below.

Norman F. Sprague III, M.D.

Age: 64

Year Appointed as Individual Trustee: 1981

Orthopedic Surgeon

Dr. Sprague, appointed as a Mesabi Trustee in 1981, is the longest serving member of the Mesabi Trustees.  Dr. Sprague received a B.S. in Geology from the University of California, Santa Barbara and a M.D. from UCLA.  Dr. Sprague also has investment experience as a general partner in two private investment partnerships.  Dr. Sprague’s thirty years experience as a Trustee makes him an important part of the institutional memory of the Mesabi Trust.

The Trust believes that each of the Individual Trustees has a diversified background and extensive financial, business and industry specific expertise that make him an important resource in the oversight of the Trust’s affairs.  There are no family relationships among any of the Individual Trustees.

ITEM 11.                                              EXECUTIVE COMPENSATION.

Compensation Discussion and Analysis

The Trust does not have a board of directors, executive officers or any employees.  The compensation paid to the Trustees is governed by the Amendment to the Agreement of Trust dated October 25, 1982, as amended (the “Amendment”).  The Trust does not use any compensation consultants.

The Amendment does not provide for any stock awards, option awards, non-equity incentive plan compensation, change in pension value, nonqualified deferred compensation earnings or any other

6

compensation.  The Trust does not have severance agreements nor does it provide post-retirement benefits to the Trustees.  Accordingly, all such tables have been omitted from this Annual Report on Form 10-K.

Pursuant to the Amendment, each Individual Trustee receives at least $20,000 in annual compensation for services as Trustee.  Each year, annual Trustee compensation is adjusted up or down (but not below $20,000) in accordance with changes from the November 1981 level of 295.5 (the “1981 Escalation Level”) in the All Commodities Producer Price Index (with 1967 = 100 as a base).  The All Commodities Producer Price Index is published by the U.S. Department of Labor, Bureau of Labor Statistics.  The adjustment is made at the end of each fiscal year and is calculated on the basis of the proportion between (a) the level of such index for the November preceding the end of such fiscal year, and (b) the 1981 Escalation Level.  Any action to modify or otherwise vary the compensation of the Individual Trustees as provided by the Amendment must be approved by the affirmative vote of 66 2/3% of the outstanding units of beneficial interest.  The Individual Trustees each received total compensation of $38,082 during fiscal 2011.

Under the Amendment, the Corporate Trustee receives annual compensation in an amount equal to the greater of (i) $20,000, or such other amount determined in accordance with the adjustments described in the preceding paragraph, or (ii) one quarter of one percent (1/4 of 1%) of the trust moneys, exclusive of proceeds of sale of any part of the Trust Estate (as such terms are defined in the Agreement of Trust), received by the Trustees and distributed to Unitholders.

Additionally, each year the Corporate Trustee receives $62,500 to cover clerical and administrative services to Mesabi Trust, other than services customarily performed by a registrar or transfer agent for which the Corporate Trustee is paid additional service fees.  The Corporate Trustee earned $133,983 in cash compensation for the fiscal year ended January 31, 2011. The Corporate Trustee also received $11,798 for its services as registrar and transfer agent for the year ended January 31, 2011.  The Corporate Trustee earned $145,781 in total compensation for the fiscal year ended January 31, 2011.

Under the Amendment, the Individual Trustees may, in extraordinary circumstances, pay additional compensation to the Corporate Trustee.  The decision to pay such compensation must be unanimously approved by the Individual Trustees.  The Corporate Trustee did not receive any compensation for extraordinary services with respect to the year ended January 31, 2011.

Trustees’ Compensation Report

The Trustees have not designated a compensation committee and are not required to do so by applicable law or regulation.  The Trustees, as a group, have reviewed and discussed the Compensation Discussion and Analysis (“CD&A”) and based on such review and discussion have recommended that the CD&A be included in this Annual Report on Form 10-K.

ITEM 12.                                              SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND TRUSTEES.

Based on information that has been obtained from Mesabi Trust’s records and a review of statements of beneficial ownership filed with Mesabi Trust pursuant to Rule 13d-102 under the Securities Exchange Act of 1934, as amended, no person known to Mesabi Trust beneficially owns more than 5% of the Trust’s Units outstanding as of April 1, 2011

The table below sets forth information as to the Units of Beneficial Interest in Mesabi Trust beneficially owned as of April 1, 2011 by the Trustees individually and as a group. Except as otherwise indicated and subject to applicable community property laws, each Trustee has sole voting and investment powers with respect to the securities listed. There were no Certificates of Beneficial Interest of Mesabi Trust owned or pledged by the Trustees as of January 31, 2011.

ITEM 13.                                              CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR INDEPENDENCE.

Mr. Richard G. Lareau, who became a Trustee on March 7, 1990, is a senior partner in the law firm of Oppenheimer Wolff & Donnelly LLP, of Minneapolis, Minnesota.  That firm has been retained by Mesabi Trust since 1961 to act with respect to matters of Minnesota law, and was retained in 1991 by the Trustees other than Mr. Lareau to act as general legal counsel.  Mesabi Trust paid Oppenheimer Wolff & Donnelly LLP (“Oppenheimer”) fees totaling $238,023 for legal services provided to the Trust during the fiscal year ended January 31, 2011 compared with fees totaling $224,796 for legal services provided to the Trust during fiscal year ended January 31, 2010.  Please see the disclosure under the heading “Trust Expenses” beginning on page 32 of the Annual Report for additional information regarding the fees paid to Oppenheimer for the Trust’s legal expenses.

Related Person Transaction Policy

During the fiscal year ended January 31, 2011, the Trustees met on a quarterly basis and reviewed and approved or ratified certain transactions that occurred during the prior fiscal quarter.  In connection with their review of the Trust’s transactions, the Trustees consider whether there have been any related person transactions.  In determining whether to approve a related person transaction, the Trustees consider the following factors, in addition to any other factors they deem necessary or appropriate:

·                  whether the transaction is expressly permitted by the Trust indenture;

·                  whether the terms are fair to the Trust;

·                  whether the transaction is material to the Trust;

·                  the role of the related person in arranging the related person transaction;

·                  the structure of the related person transaction; and

·                  the interests of all related persons in the related person transaction.

The Trust maintains a written related person transaction approval policy, which sets forth the Trust’s policies and procedures for the review, approval or ratification of any transaction required to be reported in Mesabi Trust’s filings with the Securities and Exchange Commission.  The policy applies to any financial transaction, arrangement or relationship or any series of similar transactions, arrangements or relationships in which Mesabi Trust is a participant and in which a related person has a direct or indirect interest.

Certain types of transactions, which would otherwise require review, are pre-approved by the Trustees in accordance with the policy. These types of transactions include, for example, (i) transactions, which when aggregated with the amount of all other transactions between the related person and the Trust, involve less than $120,000 in a fiscal year; (ii) transactions where the interest of the related person arises only by way of a directorship or minority stake in another organization that is a party to the transaction; (iii) transactions with a related person involving services as a bank depositary of funds, transfer agent, registrar, trustee under a trust indenture, or similar services; and (iv) a transaction that is specifically contemplated by provisions of the Trust’s indenture.

Based on their review of the Trust’s transactions during the fiscal year ended January 31, 2011, the Trustees concluded that there were no related person transactions required to be disclosed in this Annual Report on Form 10-K.

Pass-Through Royalty Trust Exemptions

Because of its legal structure and character as a pass-through royalty trust, the Trust is exempt from Rule 10A-3 of the Securities Exchange Act and the Corporate Governance Standards set forth in Section 303A of the New York Stock Exchange’s Listed Company Manual.
