Summary

What This Bill Does
This bill allows hardrock mining operators to locate multiple mill sites (up to 5 acres each) on public land for waste rock and tailings disposal. It also establishes an Abandoned Hardrock Mine Fund to remediate abandoned mines, funded by claim maintenance fees on new mill sites.

Who Benefits and How
Hardrock mining companies benefit from regulatory clarity allowing them to claim as many mill sites as "reasonably necessary" for their operations. This removes uncertainty about the number of sites that could previously be claimed. Mining equipment and services companies benefit from expanded mining operations.

Who Bears the Burden and How
Mining operators pay claim maintenance fees on new mill sites, which fund abandoned mine cleanup. Environmental groups may view expanded mill site permissions as increasing land use impacts, though savings clauses preserve existing environmental laws (Endangered Species Act, Wilderness Act, etc.).

Key Provisions
- Allows proprietors of lode/placer claims to locate as many mill sites as reasonably necessary for operations
- Each mill site limited to 5 acres, requires approved plan of operations
- Establishes Abandoned Hardrock Mine Fund funded by mill site claim fees
- Fund supports abandoned mine remediation under Infrastructure Investment and Jobs Act
- Savings clauses preserve all existing environmental protections and land withdrawals
- Mill sites cannot be patented and do not convey mineral rights
