Show full summary
- Claimants and miners: Would let a lode or placer claimant locate and include as many mill sites as reasonably necessary within an approved plan of operations. A single mill site would be limited to 5 acres and would not convey mineral rights.
- Land managers and agencies: Would authorize the Secretary of the Interior or the Secretary of Agriculture to permit mill sites on land open to location under the general mining laws while preserving existing federal authorities, withdrawals, and environmental protections.
- Cleanup and funding: Would create a separate Abandoned Hardrock Mine Fund in the Treasury funded by claim maintenance fees on mill sites. Deposits would be allocated for work under section 40704 of the Infrastructure Investment and Jobs Act and may be spent without further appropriations.

Bill Overview
Analyzed Economic Effects
2 provisions identified: 1 benefits, 0 costs, 1 mixed.
Cleanup fund for abandoned mines
If enacted, this would create the Abandoned Hardrock Mine Fund in the Treasury. Claim maintenance fees from mill sites would be deposited into the Fund. The Interior Secretary would spend the money only for cleanup projects under section 40704 of the Infrastructure Investment and Jobs Act. Money would be split and transferred as that law directs. The bill would not set a total dollar amount.
New rules for mining mill sites
If enacted, this would set clear rules for placing mining mill sites on public land. Operators would need an approved plan from Interior or Agriculture before starting. You could include as many mill site claims as reasonably needed, but each would be limited to 5 acres. Mill sites would give no mineral rights, could not be patented, and would not change any existing claim’s validity. Sites would have to be on land open to location, and federal oversight would remain.
