Company Description
Mesabi Trust (NYSE: MSB) is a royalty trust that reports in the Finance and Insurance sector under trusts, estates, and agency accounts. According to available disclosures, the trust’s principal economic interest is tied to iron ore mining activities on leased lands associated with the Peter Mitchell Mine, an iron mine located near Babbitt, Minnesota at the eastern end of the Mesabi Iron Range in the United States. Mesabi Trust does not operate the mine itself; instead, it receives royalty payments based on iron ore production and shipments from these lands.
The Polygon description and Mesabi Trust’s own filings indicate that the trust is involved in the conservation and protection of its assets and that its main wholly owned economic segment is the iron ore mining segment. Income is generated through royalty agreements under which Cleveland-Cliffs Inc. ("Cliffs"), through its subsidiary Northshore Mining Company ("Northshore"), is the lessee and operator of the leased lands. Royalty payments to Mesabi Trust are based on the volume of iron ore pellets and other iron ore products produced or shipped from Mesabi Trust lands, the pricing of iron ore product sales, and the proportion of production and shipments attributable to Mesabi Trust lands rather than non-Trust lands, as described in multiple Form 8-K filings.
Mesabi Trust’s public reports explain that the volume of iron ore pellets and other products produced or shipped by Northshore varies from quarter to quarter and year to year. Factors cited in the trust’s filings and press releases include decisions by Cliffs to idle or restart Northshore operations, requested delivery schedules of customers (including affiliates), general economic conditions in the iron ore and steel industries, production schedules, and weather conditions on the Great Lakes. These factors can cause significant variation in royalties received by Mesabi Trust and, in turn, in the funds available for distribution to unitholders.
The trust’s disclosures emphasize that royalties and distributions in any particular quarter are not necessarily indicative of royalties or distributions in subsequent periods. For example, filings and press releases note that Northshore’s operations were idled from May 2022 until April 2023, resulting in periods with no royalties, and that subsequent restarts and shipment levels affected later royalty payments. Mesabi Trust has also highlighted uncertainties related to Cliffs’ vertical supply chain planning, including its prior announcements about increasing the use of scrap iron, as well as broader volatility in the iron ore and steel industries, national and global economic uncertainties, potential changes in trade laws, the volume of unfairly traded imports, and the imposition or termination of duties or tariffs.
In addition to ongoing royalty income, Mesabi Trust has been involved in arbitration proceedings related to royalty calculations. Public press releases and Form 8-K filings describe an arbitration initiated in October 2022 against Northshore and Cliffs concerning underpayment of royalties in specific historical periods and the methodology used to price certain pellet shipments. In September 2024, the trust reported that an American Arbitration Association tribunal issued a final award in favor of Mesabi Trust for underpaid royalties in 2020, 2021, and the first four months of 2022, plus pre-award interest, and that Northshore and Cliffs paid the awarded amounts. Later, in September 2025, Mesabi Trust commenced a new arbitration seeking damages and declaratory relief relating to the idling of Northshore’s operations from May 2022 to April 2023 and alleged underpayment of royalties on intercompany shipments from 2023 onward.
Mesabi Trust’s trustees periodically declare distributions per Unit of Beneficial Interest, as described in multiple press releases and related Form 8-K filings. These announcements explain that distribution decisions take into account the total royalty payments received in prior quarters, the level of reserves the trustees determine is appropriate to meet current and future expenses and liabilities (whether fixed or contingent), and the various operational and market uncertainties noted above. The trust’s communications repeatedly state that the trustees have received no specific updates on Cliffs’ plans for Northshore’s iron ore operations or expected production, sales, or shipments for future periods.
The trust files annual reports on Form 10-K that include audited financial statements and additional detail on its royalty arrangements and financial condition. Recent press releases note that these reports are filed with the Securities and Exchange Commission and that unitholders can obtain copies of the audited financial statements referenced in those filings. Mesabi Trust also furnishes current reports on Form 8-K to summarize quarterly royalty reports and royalty payments received from Cliffs, including base and bonus royalty amounts, tons of iron ore credited as shipped in each quarter, and any adjustments related to prior periods.
Overall, Mesabi Trust functions as a royalty trust whose performance is closely linked to iron ore production and shipment activity from Mesabi Trust lands operated by Northshore and its parent Cliffs. Its public disclosures focus on royalty calculations, variability in iron ore shipments and pricing, distribution decisions, and legal proceedings related to royalty entitlements.
Business model and revenue sources
According to Mesabi Trust’s Form 8-K filings and press releases, the trust’s revenue is derived from royalty payments calculated on shipments of iron ore products by Northshore from Mesabi Trust lands. The filings describe two main royalty components: a base royalty and a bonus royalty, both determined by the volume of iron ore pellets and other products produced or shipped during the quarter and year to date, and by the pricing of iron ore product sales. The percentage of production and shipments sourced from Mesabi Trust lands versus non-Trust lands is also a key factor in determining the royalty amounts.
Royalty reports received from Cliffs detail tons of iron ore shipped in each quarter and the corresponding base and bonus royalty credits to Mesabi Trust, as well as any adjustments related to prior quarters and amounts paid to the Mesabi Land Trust. These reports form the basis for the total royalty payments Mesabi Trust receives and subsequently discloses in its SEC filings.
Operational dependencies and risk factors as disclosed
Mesabi Trust’s disclosures emphasize that its financial results depend on operational decisions made by Cliffs and Northshore, which control the level of iron ore production and shipments from the leased lands. The trust has publicly reported that Cliffs’ decisions to idle Northshore operations, such as the idling from May 2022 until April 2023, directly affect the royalties received. The trust also notes that requested delivery schedules of customers (including affiliates), general economic conditions in the iron ore industry, and production schedules and weather conditions on the Great Lakes influence shipment volumes and, therefore, royalty income.
Press releases and Form 8-K filings further highlight broader uncertainties, including volatility in the iron ore and steel industries, national and global economic conditions, potential changes in trade laws, the volume of unfairly traded imports, and changes in international duties or tariffs. The trust references Cliffs’ prior public announcements about its vertical supply chain planning and increased use of scrap iron as additional sources of uncertainty for future iron ore production and shipments from Northshore.
Legal and arbitration matters
Mesabi Trust has disclosed arbitration proceedings with Northshore and Cliffs relating to royalty calculations and operational decisions. In October 2022, the trust initiated arbitration through the American Arbitration Association, alleging underpayment of royalties in 2020, 2021, and early 2022 due to the failure to use the highest priced arm’s-length iron ore pellet sale from the preceding four quarters in pricing certain pellet shipments. The trust also sought declaratory relief regarding its entitlement to documentation and the timing of royalty obligations. In September 2024, Mesabi Trust reported that the arbitration tribunal issued a final award granting damages and pre-award interest, and that Northshore and Cliffs paid the awarded amounts the following month.
In September 2025, Mesabi Trust commenced a new arbitration against Northshore and Cliffs, seeking damages and declaratory relief related to the idling of Northshore’s operations from May 2022 to April 2023 and alleged underpayment of royalties on intercompany shipments from 2023 onward. These proceedings, as described in Form 8-K and press releases, illustrate the trust’s efforts to enforce its royalty rights under existing agreements.
Regulatory reporting and governance structure
Mesabi Trust is organized under the laws of New York, as indicated in its Form 8-K cover pages, and reports under Commission File Number 1-4488.
