What is the scope of these regulations?

These regulations govern locating, recording, and maintaining mining claims, mill sites, and tunnel sites on all Federal lands. These regulations do not authorize locating any new mining claims on Federal lands closed to mineral entry, including units of the National Park Service. (a) You must follow the recording and maintenance requirements in this part even if BLM has actual knowledge of the existence of your mining claims or sites through other means. (b) Part 3838 of this chapter describes supplemental procedures for locating mining claims or sites on land subject to the Stockraising Homestead Act, 43 U.S.C. 291-299. (c) BLM is not the official recording office for ancillary documents concerning mining claims or sites, including but not limited to, leases, wills, judgments, liens, option agreements, and grubstake contracts.
