                                     PART I

ITEM 1.    BUSINESS.

           (a)  GENERAL DEVELOPMENT OF BUSINESS.

           The information under the headings "Mesabi Trust," "The Trust
Estate," "Leasehold Royalties" and "Land Trust and Fee Royalties" set forth on
pages 9 through 13 of the Annual Report of the Trustees of Mesabi Trust for the
fiscal year ended January 31, 2001 (the "Annual Report") is incorporated herein
by reference. Certain capitalized terms used below in this Part I are defined in
the Annual Report.

           Mesabi Trust ("Mesabi Trust" or the "Trust"), formed pursuant to an
Agreement of Trust dated July 18, 1961 (the "Agreement of Trust"), is a trust
organized under the laws of the State of New York. Mesabi Trust holds all of the
interests formerly owned by Mesabi Iron Company, including all right, title and
interest in the Amended Assignment of Peters Lease, the Amended Assignment of
Cloquet Lease, the beneficial interest in the Mesabi Land Trust and all other
assets and property identified in the Agreement of Trust. The Amended Assignment
of Peters Lease relates to an Indenture made as of April 30, 1915 among East
Mesaba Iron Company, Dunka River Iron Company and Claude W. Peters (the "Peters
Lease") and the Amended Assignment of Cloquet Lease relates to an Indenture made
May 1, 1916 between Cloquet Lumber Company and Claude W. Peters (the "Cloquet
Lease").

           The Trust will terminate twenty-one (21) years after the death of the
survivor of twenty-five (25) persons named in an exhibit to the Agreement of
Trust. The youngest person on this exhibit is now 40 years old.

           (b)  FINANCIAL INFORMATION ABOUT INDUSTRY SEGMENTS.

           Substantially all of the Trust's revenue, operating profits and
assets relate to one business segment--iron ore mining.

           (c)  NARRATIVE DESCRIPTION OF BUSINESS.

           The Agreement of Trust specifically prohibits the Trustees from
entering into or engaging in any business. This prohibition applies even to
business activities the Trustees deem necessary or proper for the conservation
and protection of the Trust Estate. Accordingly, the Trustees' activities in
connection with the administration of Trust assets are limited to collecting
income, paying expenses and liabilities, distributing net income and protecting
and conserving the assets held.

           Pursuant to a ruling from the Internal Revenue Service, which ruling
was based on the terms of the Agreement of Trust including the prohibition
against entering into any business, the Trust is not taxable as a corporation
for Federal income tax purposes. Instead, the holders of the Units of Beneficial
Interest (the "Unitholders") are considered as "owners" of the Trust and the
Trust's income is taxable directly to the Unitholders.

           Leasehold royalty income constitutes the principal source of the
Trust's revenue. Royalty rates are determined in accordance with the terms of
Mesabi Trust's leases and assignments of leases. Until August 17, 1989, the
overriding royalty was based on the quantity and iron content of pellets shipped
by Reserve Mining Company ("Reserve") from Mesabi Trust lands, although Mesabi
Trust did not receive any royalty income from May 1986 until July 1990 because
Reserve filed a Chapter 11 bankruptcy petition and suspended its operations. On
August 17, 1989, Cyprus Northshore Mining Corporation ("Cyprus NMC") purchased
substantially all of Reserve's assets, including Reserve's interest in the
Mesabi Trust lands. At the same time, Mesabi Trust entered into certain
agreements with Reserve's


                                       2
<PAGE>

Chapter 11 Trustee and Cyprus NMC (the "Amended Assignment Agreements"). The
Amended Assignment Agreements modified the method of calculating overriding
royalties payable to Mesabi Trust and transferred Reserve's interest in the
Mesabi Trust lands to Cyprus NMC. Pursuant to the Amended Assignment Agreements,
overriding royalties are determined by both the volume and selling price of iron
ore products shipped. In 1994, Cyprus NMC was sold by its parent corporation to
Cleveland-Cliffs Inc. ("CCI") and renamed Northshore Mining Corporation
("Northshore"). CCI now operates Northshore as a wholly-owned subsidiary.

           In its Annual Report for the year ended December 31, 1999 ("CCI's
Annual Report"), CCI, parent company of Northshore, the lessee/operator of
Mesabi Trust iron ore interests, stated that it was continuing to evaluate
whether to build a facility to produce pig iron at CCI's Northshore Mine in
Minnesota that would produce premium grade pig iron. CCI's Annual Report stated
that while progress has been made in a number of areas on the project, a
decision relative to proceeding with this project has been delayed by
uncertainty about market conditions and timing of state environmental
permitting. Except for its May 2000 announcement regarding environmental
permitting for the facility (see below), CCI has made no public disclosure
regarding the pig iron facility project since CCI's Annual Report. (CCI made no
reference to the project in its Annual Report for the year ended December 31,
2000.) Because of the preliminary nature of this information, the Mesabi
Trustees are unable to determine at this time how the addition of a pig iron
facility (if the project proceeds) would impact overall revenues of Mesabi
Trust. As indicated elsewhere in this report, the Trust's revenues are currently
derived almost entirely from iron ore pellet production and sales.

           Following LTV Steel's decision to close the LTV Steel Mining
Company's plant at Hoyt Lakes, Minnesota this year, CCI announced in May 2000
that it has asked the Minnesota Pollution Control Agency to delay a decision on
environmental permitting for the possible pig iron facility at CCI's Northshore
Mine in order to evaluate whether its iron ore pellet production should be
increased to meet CCI's future sales requirements. CCI stated that the requested
delay should not be interpreted to mean that CCI has abandoned plans for a
possible pig iron facility. CCI reported that it will be supplying LTV with a
majority of its iron ore pellets over the next 10 years with most of the pellets
expected to come from Minnesota sources that are owned or managed by CCI.
Besides potential expansion at CCI's Northshore Mine, CCI announced that it is
reviewing ways to increase production levels at other CCI-managed mines.

           Additionally, in a press release dated January 9, 2001, CCI announced
that it intends to reduce iron ore pellet production at the Northshore Mine by
approximately 700,000 tons in 2001. CCI stated that one of the pellet production
furnaces at the Northshore Mine would be shut down for an estimated nine month
period beginning in January. CCI cited the impact on its customers of perceived
unfairly traded imports and the general deterioration in overall steel demand in
North America as reasons for the production cutback. No forecast of the volume
of shipments of iron ore pellets for 2001 was provided.

           Mesabi Trust has no employees, but it engages independent consultants
to assist the Trustees in monitoring, among other things, the amount and sales
prices of minerals shipped by Northshore from Silver Bay, Minnesota. As noted
above, the information regarding amounts and sales prices of shipped minerals is
used to compute the royalties payable to Mesabi Trust by Northshore. Bankers
Trust Company, one of the Trustees, also performs certain administrative
functions for Mesabi Trust.

ITEM 2.    PROPERTIES.

           The information under the heading "The Trust Estate" set forth on
page 9 of the Annual Report of the Trustees of Mesabi Trust for the fiscal year
ended January 31, 2001 is incorporated herein by reference.


                                       3

           The Peters Lease provides that each leasehold estate will continue
until the reserves of iron ore, taconite and other minerals or materials on the
land subject to the Peters Lease are exhausted. The Mesabi Lease terminates when
the Peters Lease terminates. The Cloquet Lease, executed in 1916, terminates in
the year 2040. If Northshore decides to terminate or surrender one or more of
these leases, it must first give Mesabi Trust at least six months' notice of its
intention to do so and, at Mesabi Trust's request, reassign all of such leases
to Mesabi Trust. If any such reassignment occurs, Northshore must transfer the
lease interests to Mesabi Trust free and clear of liens, except public highways.
In return, Mesabi Trust must assume Northshore's future obligations as lessee
under the reassigned leases.

           The Trustees have neither made nor caused to be made any surveys or
test drillings to ascertain the iron ore reserves on any land subject to the
Peters Lease or the Cloquet Lease. However, initial surveys and test drillings
made by Mesabi Iron Company many years ago indicated that these lands contained
accessible reserves of at least 1-1/2 billion tons of mineable raw material,
capable of yielding approximately 500 million tons of concentrated product. In
CCI's 2000 Annual Report, CCI estimated that there currently remains enough ore
reserve in the Peters and Cloquet Lease Lands to produce concentrated product
for 81 years of mining at the then current extraction rates. Little or no
commercial ore deposits exist in the Mesabi Lease Lands.

                                    PART III

ITEM 10.   DIRECTORS AND EXECUTIVE OFFICERS OF THE REGISTRANT.

           There are no directors or executive officers of the registrant. The
Agreement of Trust provides for a Corporate Trustee and four Individual Trustees
(collectively, the "Trustees"). Generally, Trustees continue in office until
their resignation or removal. Any Trustee may be removed at any time, with or
without cause, by the holders of two-thirds in interest of the Trust
Certificates then outstanding. In the case of an Individual Trustee, a successor
is also 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 also 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.

           The present Trustees of Mesabi Trust and their respective ages, terms
in office as Trustees, and business experience during the past five years are

ITEM 11.   TRUSTEES' COMPENSATION.

           The Agreement of Trust was amended October 25, 1982 (the
"Amendment"). 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. 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.

           Also pursuant to the Amendment, Bankers Trust Company, as 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 Trust Agreement),
received by the Trustees and distributed to Trust Certificate Holders.

           Additionally, each year the Corporate Trustee receives $62,500 (or
more, if unanimously approved by the Individual Trustees) to cover clerical and
administrative services to Mesabi Trust other than services customarily
performed by a registrar or transfer agent.

           The following table sets forth the cash compensation paid to the
Trustees through January 31, 2001, for services in all capacities as Trustees to
Mesabi Trust during the fiscal year ended January 31, 2001.
