Mineral Rights

Also known as: subsurface rights, mining rights, oil and gas rights, mineral estate

Ownership rights to subsurface resources — oil, gas, metals, and other minerals — beneath a parcel of land, which can be legally separated from surface ownership and transferred independently.

Mineral rights represent the legal ownership of subsurface resources — oil, natural gas, coal, metals, and other minerals — beneath a parcel of land. In the United States, mineral rights can be severed from surface rights, meaning one party can own the land and structures above ground while a different party owns the resources below. Once severed, mineral rights are bought, sold, and leased independently of the surface estate, and the separation is recorded in the property's title history.

For mortgage note investors, mineral rights matter primarily in regions with active extraction industries — parts of Texas, Oklahoma, Pennsylvania, North Dakota, and Appalachia, among others. When mineral rights have been severed from the surface estate, the property securing the mortgage may be worth less than comparable properties that retain their mineral rights, because a portion of the land's total value has been stripped away. Additionally, active mineral leases can grant third parties the right to access the surface for drilling or mining operations, which can affect property usability and marketability. A thorough title search will reveal whether mineral rights have been severed, and this information should be factored into the collateral valuation during due diligence.
