				  812.11(15) (c).
(3) "Department" means the department of
				  natural resources.
(4) "Driller"
				  means a person who performs core, rotary, percussion, or other drilling
				  involved in exploration for nonferrous metallic minerals.

(6) "Drilling site"
				  means the area disturbed by exploration including the drillhole, drill pad,

(8) "Exploration"
				  means the on-site geologic examination from the surface of an area by core,
				  rotary, percussion, or other drilling, where the diameter of the hole does not
				  exceed 18 inches, for the purpose of searching for nonferrous metallic minerals
				  or establishing the nature of a known nonferrous metallic mineral deposit and
				  includes associated activities such as clearing and preparing drilling sites
				  and constructing access roads. For the purposes of the definition of
				  exploration, geologic examination does not include drillholes constructed for
				  the purpose of collecting soil samples, conducting geophysical surveys or
				  groundwater investigations, or determining radioactivity by means of placement
				  of radiation-sensitive devices.

				  " Exploration license" means the license required under s.
				  293.21(2),
				  Stats., as a condition of engaging in exploration.
(10) "Flowing drillhole" means a drillhole

(11) "License year" means the period
				  commencing on July 1 of any year and ending on the following June 30.
(11m) "Metallic sulfide-bearing rock" means
				  native rock formations that contain an average metallic sulfide content of 3
				  percent or greater, by volume, for the purposes of management and disposal of
				  drilling mud and cuttings under this subchapter.
(12) "Neat cement grout" means a mixture of
				  cement and water meeting the material specifications of s.
				  NR
				  812.11(15) (b). Powdered bentonite
				  may be added up to a ratio of 5 pounds per 94-pound bag of cement.
(12m) "Nonferrous metallic mineral" has the
				  meaning given in s.
				  293.01(12m),
				  Stats.
(13) "Parcel" means an
				  identified section, fractional section, or government lot.
(14) "Permanent abandonment" means filling an
