Mesabi Trust (MSB) is a royalty trust that holds leasehold and fee interests in iron ore properties on the Mesabi Iron Range in Minnesota. It makes money by collecting royalties tied to iron ore production from those properties, passing substantially all revenue through to certificate holders as distributions. The trust is administered by Deutsche Bank Trust Company Americas as Corporate Trustee, with individual trustees receiving compensation adjusted annually via the All Commodities Producer Price Index. Substantially all revenue, as noted in the 10-K filed 2026-04-22 for the fiscal year ended January 31, 2026, derives from these royalty streams, with no operating segments beyond the trust estate itself. The trust structure means there is no active management of mining operations; income depends entirely on the volume and pricing of iron ore extracted by the lessee.
