ITEM 2.      TRUSTEES' DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
             RESULTS OF OPERATIONS.

FORWARD-LOOKING INFORMATION

           Certain statements contained in this document are forward-looking,
including specifically those statements estimating calendar year 2000 production
or shipments. All such forward-looking statements are based on input from the
lessee/operator. The Trust has no control over the operations and activities of
the lessee/operator except within the framework of current agreements. Actual
results could differ materially from those indicated in such statements.
Important factors that could cause actual results to differ materially include
those listed in "Important Factors Affecting Mesabi Trust" below.

BACKGROUND

           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. Three types of royalties
comprise the Trust's leasehold royalty income:

              -   Overriding royalties, which constitute the majority of Mesabi
                  Trust's royalty income, are determined by both the volume and
                  selling price of iron ore products shipped.

              -   Fee royalties, historically a smaller component of the Trust's
                  royalty income, are payable to Mesabi Land Trust, a Minnesota
                  land trust of which Mesabi Trust is the sole beneficiary
                  ("Mesabi Land Trust"), and are based on the amount of crude
                  ore mined. Currently, the fee royalty on crude ore is based on
                  an agreed price per ton, subject to certain indexing. Crude
                  ore is used to produce iron ore pellets and other products.

              -   Minimum advance royalties, the third type of royalty, are
                  discussed below.

           With respect to the volume component of royalty calculation,
Northshore Mining Company ("Northshore") is obligated to pay Mesabi Trust base
overriding royalties in varying amounts. The volume component of overriding
royalties constitutes a percentage of the gross proceeds of iron ore products
produced at Mesabi Trust lands (and to a limited extent other lands) and shipped
from Silver Bay, Minnesota. The percentage ranges from 2-1/2% of the gross
proceeds for the first one million tons of iron ore products so shipped annually
to 6% of the gross proceeds for all iron ore products in excess of 4 million
tons so shipped annually.

           With respect to the selling price component of overriding royalty
calculation, Northshore is obligated to pay to Mesabi Trust royalty bonuses. The
royalty bonus is a percentage of the gross proceeds of product shipped from
Silver Bay and sold at prices above a threshold price. The threshold price is
adjusted on an annual basis for inflation and deflation (but not below $30). The
threshold price was $37.29 for calendar year 1997, was $38.21 for calendar year
1998, was $38.22 for calendar year 1999 and is $38.82 for calendar year 2000.
The royalty bonus percentage ranges from 1/2 of 1% of the gross proceeds (on all
tonnage shipped for sale at prices between the threshold price and $2.00 above
the threshold price) to 3% of the gross proceeds on all tonnage shipped for sale
at prices $10.00 or more above the threshold price. No royalty bonus has been
paid to date.

           Generally, Northshore's obligation to pay base overriding royalties
and royalty bonuses with respect to the sale of iron ore products accrues upon
the shipment of those products from Silver Bay. However, regardless of whether
any shipment has occurred, Northshore is obligated to pay to Mesabi Trust a
minimum advance royalty. Each year, the amount of the minimum advance royalty is
adjusted for


                                       6
<PAGE>

inflation and deflation (but not below $500,000 per annum). Advance royalties
payable were $621,606 for calendar year 1997, were $636,935 for calendar year
1998, were $637,044 for calendar year 1999 and are $647,282 for calendar year
2000. Until overriding royalties (and royalty bonuses, if any) for a particular
year equal or exceed the minimum advance royalty for the year, Northshore must
make quarterly payments of up to 25% of the minimum advance royalty for the
year. Because advance minimum royalties are essentially prepayments of base
overriding and bonus royalties earned each year, any advance minimum royalties
paid in a fiscal quarter are recouped by credits against base overriding and
bonus royalties earned in later fiscal quarters during the year. Historically,
advance minimum royalties have been paid in the first fiscal quarter and
recouped in the second fiscal quarter.

           Northshore is obligated to make quarterly royalty payments in
January, April, July and October of each year. In the case of base overriding
royalties and royalty bonuses, these quarterly royalty payments are to be made
whether or not the related proceeds of sale have been received by Northshore by
the time such payments become due.

           Under the relevant documents, Northshore may mine and ship iron ore
products from lands other than Mesabi Trust lands. To encourage the use of iron
ore products from Mesabi Trust lands, Mesabi Trust receives royalties on stated
percentages of iron ore shipped from Silver Bay, whether or not the iron ore
products are from Mesabi Trust lands. Mesabi Trust receives royalties at the
greater of (i) the aggregate quantity of iron ore products shipped that were
from Mesabi Trust lands, and (ii) a portion of the aggregate quantity of all
iron ore products shipped that were from any lands, such portion being 90% of
the first four million tons shipped during such year, 85% of the next two
million tons shipped during such year, and 25% of all tonnage shipped during
such year in excess of six million tons.

           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 stated in the Report
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. Such statements were previously included in CCI's Annual Report for
the year ended December 31, 1998. 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 recently announced decision to close the LTV
Steel Mining Company's plant at Hoyt Lakes, Minnesota next year, CCI recently
announced 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.

           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 iron ore products shipped by Northshore from Silver Bay, Minnesota. As
noted above, the information regarding amounts and sales prices of shipped iron
ore products is used to compute the royalties payable to Mesabi Trust by
Northshore.

Bankers Trust Company, the Corporate Trustee, also performs certain
administrative functions for Mesabi Trust.

IMPORTANT FACTORS AFFECTING MESABI TRUST

           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 preservation
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.

           Accordingly, the income of the Trust is highly dependent upon the
activities and operations of Northshore, and the terms and conditions of the
Amended Assignment Agreements. The Trust and the Trustees have no control over
the operations and activities of Northshore, except within the framework of the
Amended Assignment Agreements.

           Due to winter weather, and the increasing royalty percentages based
on tonnage shipped in a calendar year, results for a particular calendar quarter
are typically not indicative of results for future quarters or the year as a
whole. Factors which can impact the results of the Trust in any quarter or year
include:

1.      SHIPPING CONDITIONS IN THE GREAT LAKES. Shipping activity by Northshore
        is dependent upon when the Great Lakes shipping lanes freeze for the
        winter months (typically in January) and when they re-open in the spring
        (typically late-March or April). Base overriding royalties to Mesabi
        Trust are based on shipments made in a calendar quarter. Because there
        typically is little or no shipping activity in the first calendar
        quarter, the Trust typically receives only the minimum royalty for that
        period.

2.      OPERATIONS OF NORTHSHORE. Because the primary portion of the Trust's
        revenues derive from iron ore product shipped by Northshore from Silver
        Bay, Northshore's processing and shipping activities directly impact the
        Trust's revenues in each quarter and for each year. In turn, a myriad of
        factors affect Northshore shipment volume. These factors include
        economic conditions in the iron ore industry, pricing by competitors,
        long-term customer contracts or arrangements by Northshore or its
        competitors, availability of ore boats, production at Northshore's
        mining operations, and production at the pelletizing/processing
        facility. If any pelletizing line becomes idle for any reason,
        production and shipments (and, consequently, Trust income) could be
        adversely impacted. For further information regarding operations of
        Northshore, see "Recent Developments" on page 9.

3.      INCREASING ROYALTIES. As described elsewhere in this Report, the royalty
        percentage paid to the Trust increases as the aggregate tonnage of iron
        ore products shipped, attributable to the Trust, in any calendar year
        increases. Assuming a consistent sales price per ton throughout a
        calendar year, shipments of iron ore product attributable to the Trust
        later in the year generate a higher royalty to the Trust.

4.      PERCENTAGE OF MESABI TRUST ORE. As described elsewhere in this Report,
        Northshore has the ability to process and ship iron ore product from
        lands other than Mesabi Trust lands. In certain circumstances, the Trust
        may be entitled to royalties on those other shipments, but not in all
        cases. In general, the Trust will receive higher royalties (assuming all
        other factors are equal) if a higher percentage of shipments are from
        Mesabi Trust lands. The percentages of shipments that came


                                       8
<PAGE>

        from Mesabi Trust lands were 98.9%, 99.3%, 98.3%, 98.4% and 90.6% in
        calendar years 1999, 1998, 1997, 1996 and 1995, respectively.

COMPARISON OF THREE MONTHS ENDED APRIL 30, 2000 AND APRIL 30, 1999

           Mesabi Trust's net income decreased to $352,210 for the fiscal
quarter ended April 30, 2000, as compared to net income of $370,043 for the
fiscal quarter ended April 30, 1999. Mesabi Trust's gross income for the fiscal
quarter ended April 30, 2000 was $443,829, consisting of $352,649 in minimum
advance royalty income, $0 in overriding royalty income, $80,822 in fee royalty
income and $10,358 in interest income, as compared to gross income of $455,960
consisting of $354,467 in minimum advance royalty income, $0 in overriding
royalty income, $89,464 in fee royalty income and $12,029 in interest income,
for the fiscal quarter ended April 30, 1999. The decrease in royalty income was
primarily due to decreased pellet shipments as compared to the comparable prior
period. Mesabi Trust's expenses for the fiscal quarter ended April 30, 2000 were
$91,619, compared to expenses of $85,917 for the fiscal quarter ended April 30,
1999.

           Mesabi Trust's Unallocated Reserve aggregated $1,115,587 at April 30,
2000, as compared with an Unallocated Reserve of $1,082,995 at April 30, 1999.
The increase of $32,592 was due to the net effect of: (a) the decrease in net
income of $17,833 during the three months ended April 30, 2000 as compared with
the three months ended April 30, 1999 and (b) the January 31, 2000 unallocated
reserve balance of $763,377 was $50,425 higher than the January 31, 1999
unallocated reserve balance of $712,952. The Trustees anticipate that the amount
of Unallocated Reserve will fluctuate from time to time, depending upon a number
of factors, including but not limited to the income for a particular period, the
amount and timing of distributions, uncertainty about future royalty income and
the uncertainty of future expenses.

RECENT DEVELOPMENTS

           The Trustees of Mesabi Trust have learned through a public
announcement by CCI, the corporate parent of Northshore, that CCI 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. CCI
announced that it made this request in order to evaluate whether its iron ore
pellet production should be increased to meet CCI's future sales requirements
following LTV Steel's decision announced in May 2000 to close the LTV Steel
Mining Company's plant at Hoyt Lakes, Minnesota next year. CCI reported


                                       9
<PAGE>

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 and that the requested delay in environmental
permitting should not be interpreted to mean that CCI has abandoned plans for a
possible pig iron facility. Increasing production levels at the Northshore
plant, however, would presumably require additional capital investment to
increase plant capacity, about which the Trustees have no information. Based on
this public announcement by CCI, the Mesabi Trustees anticipate that if this
potential plant expansion is achieved, production levels of iron ore pellets
could, over time, increase at the Northshore plant. If such an increase in iron
ore pellet production levels results in increased shipments of iron ore pellets,
overall revenues of Mesabi Trust would be positively impacted.
