Briefly, a mineral interest is part of the ownership rights related to owning real property. The owner of a mineral interest owns all or part of the mineral estate. The owner of the mineral estate typically holds the right to search for, develop and produce minerals from the property. A mineral interest can be severed from the surface rights and can be sold or leased separately from the surface once it is severed from the surface. Usually, the owner of the mineral estate holds the right to use the surface to the extent that is reasonably necessary to extract the minerals (implied easement). Just as one may have multiple owners of the surface, there may be multiple owners of the mineral interests. Each mineral interest holder may have different rights. The holders of the mineral interests together own the mineral estate.
