(a) The provisions of the Wilderness Act do not prevent any activity, including prospecting, within National Forest Wilderness for the purpose of gathering information about mineral or other resources if such activity is conducted in a manner compatible with the preservation of the wilderness environment. While information gathered by prospecting concerning mineral resources within National Forest Wilderness may be utilized in connection with the location of valuable mineral deposits which may be discovered through such activity and which may be open to such location, attention is directed to the fact that no claim may be located after midnight, December 31, 1983, and no valid discovery may be made after that time on any location purportedly made before that time.

(b) All persons wishing to carry on any activity, including prospecting, for the purpose of gathering information about mineral or other resources on lands within National Forest Wilderness should make inquiry of the officer in charge of the National Forest in which the lands are located concerning the regulations of the Secretary of Agriculture governing surface use of the lands for such activity.
