(a) The owner or operator of a producing mine may request permission to state an average figure for the items required by paragraphs (d) to (i) of subsection (1) of this section based on any three-year, five-year, or ten-year period immediately preceding January 1 of the year in which the statement must be filed. The same reporting method shall be used for all annual statements filed in a single year pertaining to a particular mine.

(b)

(I) The owner or operator may make an initial request pursuant to this subsection (1.4) by filing the request with the board of county commissioners of each county in which the mine is located at least forty-five days prior to the reporting date specified in the introductory portion to subsection (1) of this section and attaching a copy of the request to the annual statement filed pursuant to subsection (1) of this section with the county assessor of each county in which the mine is located.

(II) The owner or operator may make subsequent changes in the reporting method pursuant to this subsection (1.4) by filing a request for a change in the reporting method with the board of county commissioners and the county assessor of every county in which the mine is located at least forty-five days prior to the reporting date specified in the introductory portion to subsection (1) of this section.

(d) The fact that authorization to alter the reporting method has not been received from all or any of the boards of county commissioners for the counties in which the mine is located shall not relieve the owner or operator from the obligation to file the annual statement pursuant to subsection (1) of this section with all counties in which the mine is located.

(3) If any mining claim or other land is owned by the same person operating a producing mine which is contiguous to said claim and if, during the preceding calendar year, ore was actually extracted from said claim or other land or transported through such claim or other land by cut or tunnel or if any phase of the operation of said producing mines was conducted on such claim or other land, then such claim or other land shall be deemed to be a part of such producing mine and assessed therewith. All other claims or other land under the same ownership shall be valued in the same manner as other real property, on an acreage basis, regardless of surface contiguity.

(4) If any mining claim comprising part of the mining property of a producing mine is not patented or entered for patent, then the possessory interest therein shall be the subject of taxation.
