I'm speaking of the 1988 Caving Act:
TITLE 16 - CONSERVATION
CHAPTER 63 - FEDERAL CAVE RESOURCES PROTECTION
Sec. 4308. Miscellaneous provisions
(d) Existing rights
Nothing in this chapter shall be deemed to affect the full
operation of the mining and mineral leasing laws of the United
States, or otherwise affect valid existing rights.
-SOURCE-
(Pub. L. 100-691, Sec. 9, Nov. 18, 1988, 102 Stat. 4550.)
