Key points
  • Lets a claim holder locate as many mill sites as are reasonably necessary for operations tied to a lode or placer claim within an approved plan of operations, with each site capped at 5 acres
  • Provides that a mill site conveys no mineral rights, does not affect existing claims, and cannot be patented
  • Creates the Abandoned Hardrock Mine Fund in the Treasury, funded by claim maintenance fees on these mill sites and spent only to carry out section 40704 of the Infrastructure Investment and Jobs Act
  • Amends the Omnibus Budget Reconciliation Act of 1993 to replace references to the Mining Law of 1872 with sections 2319 through 2344 of the Revised Statutes
