Mesabi Trust engages in the business of collecting income, paying expenses and liabilities, distributing net income to the holders of Trust certificates after the payment of, or provision for, such expenses and liabilities, and protecting and conserving the assets held. The company is headquartered in New York City, New York and currently employs 0 full-time employees. The Trust is a pass-through entity. The company operates in one segment, which is iron ore mining. The mine is operated by Northshore Mining Company (Northshore), a subsidiary of Cleveland-Cliffs Inc. (CCI). Northshore mines the ore, which is in the form of taconite, a hard rock containing approximately 21% recoverable iron, crushes it, separates the iron particles from the non-metallic, and forms the resulting concentrate into pellets which are shipped for use in steel-producing blast furnaces of customers of CCI. Northshore pays royalties to the Trust primarily based on the selling price of pellets shipped from Northshore’s pellet plant at Silver Bay, Minnesota, on Lake Superior approximately 45 miles from the mine, plus a significantly smaller royalty based on tons of ore extracted at the mine.
