Item 8.01 Other Events.

On November 19, 2012, Cliffs Natural Resources Inc. ("Cliffs") announced that, effective January 5, 2013, it will idle two of the four production lines at its wholly-owned subsidiary, Northshore Mining Company ("Northshore"). Cliffs explained that it is adjusting its 2013 operating plans for its North American iron ore businesses to align with expected sales volumes. Cliffs noted that the "production decreases are driven by increased iron ore pricing volatility and lower North American steelmaking utilization rates." Cliffs did not announce how much total production or shipments at Northshore will be impacted in 2012 or 2013, stating only that "full-year 2013 expected sales volumes for U.S. Iron Ore remain unchanged at 19 to 20 million tons as previously disclosed by Cliffs." Cliffs also announced that the production curtailments at Northshore will impact approximately 125 employees at Northshore.

Mesabi Trust receives royalties based on the volume of shipments and the selling prices of iron ore products shipped by Northshore, the lessee/operator of the Mesabi Trust lands. The Trustees of Mesabi Trust have not received any information regarding the estimated volume of shipments from Northshore during the remainder of 2012 or 2013. Therefore, the Trust cannot predict what impact the recently announced production curtailment will have on the Trust's future royalties to be received from Northshore.

Safe Harbor Statement under the Private Securities Litigation Reform Act of 1995

This Current Report on Form 8-K contains certain forward-looking statements with respect to iron ore pellet production, iron ore pricing, shipments by Northshore in 2013, royalty amounts, which statements are intended to be made under the safe harbor protections of the Private Securities Litigation Reform Act of 1995, as amended. Actual production, prices and shipments of iron ore pellets, as well as actual royalty levels (including bonus royalties) could differ materially from current expectations due to inherent risks such as general and industry economic trends, uncertainties arising from war, terrorist events and other global events, higher or lower customer demand for steel and iron ore, environmental compliance uncertainties, higher imports of steel and iron ore substitutes, processing difficulties, consolidation and restructuring in the domestic steel market, indexing features in Cliffs customer agreements resulting in adjustments to royalties payable to the Trust and other factors. Further, substantial portions of royalties earned by Mesabi Trust are based on estimated prices that are subject to interim and final adjustments, which can be positive or negative, and are dependent in part on multiple price and inflation index factors under Cliffs customer agreements to which the Trust is not a party and that are not known until after the end of a contract year. It is possible that future negative price adjustments could offset, or even eliminate, royalties or royalty income that would otherwise be payable to the Trust in any particular quarter, or at year end, thereby potentially reducing cash available for distribution to the Trust's Unitholders in future quarters. 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.
