26 U.S.C. § 614
Definition of property
For the purpose of computing the depletion allowance in the case of mines, wells, and other natural deposits, the term “property” means each separate interest owned by the taxpayer in each mineral deposit in each separate tract or parcel of land.
Any election provided in paragraph (2) shall be made for each operating mineral interest, in the manner prescribed by the Secretary by regulations, not later than the time prescribed by law for filing the return (including extensions thereof) for the first taxable year in which any expenditure for development or operation in respect of such operating mineral interest is made by the taxpayer after the acquisition of such interest.
Any election under paragraph (2) shall be for all purposes of this subtitle and shall be binding on the taxpayer for all subsequent taxable years.
Except in the case of oil and gas wells and geothermal deposits, if a single tract or parcel of land contains a mineral deposit which is being extracted, or will be extracted, by means of two or more mines for which expenditures for development or operation have been made by the taxpayer, then the taxpayer may elect to allocate to such mines, under regulations prescribed by the Secretary, all of the tract or parcel of land and of the mineral deposit contained therein, and to treat as a separate property that portion of the tract or parcel of land and of the mineral deposit so allocated to each mine. A separate property formed pursuant to an election under this paragraph shall be treated as a separate property for all purposes of this subtitle (including this paragraph). A separate property so formed may, under regulations prescribed by the Secretary, be included as a part of an aggregation in accordance with paragraphs (1) and (3). The election provided by this paragraph may not be made with respect to any property which is a part of an aggregation formed by the taxpayer under paragraph (1) except with the consent of the Secretary.
For purposes of this section, the term “operating mineral interest” includes only an interest in respect of which the costs of production of the mineral are required to be taken into account by the taxpayer for purposes of computing the taxable income limitation provided for in section 613, or would be so required if the mine, well, or other natural deposit were in the production stage.
If a taxpayer owns two or more separate nonoperating mineral interests in a single tract or parcel of land or in two or more adjacent tracts or parcels of land, the Secretary shall, on showing by the taxpayer that a principal purpose is not the avoidance of tax, permit the taxpayer to treat (for all purposes of this subtitle) all such mineral interests in each separate kind of mineral deposit as one property. If such permission is granted for any taxable year, the taxpayer shall treat such interests as one property for all subsequent taxable years unless the Secretary consents to a different treatment.
For purposes of this subsection, the term “nonoperating mineral interests” includes only interests which are not operating mineral interests.
