Show full summary
- Miners and operators can include as many mill sites as are "reasonably necessary" inside an approved plan. Each site is limited to 5 acres, conveys no mineral rights, and cannot be patented.
- Current claimants keep their entry, use, and occupancy rights and some pre-withdrawal rights can be restored. The bill also harmonizes legal definitions and references across mining laws to reduce confusion about claims and fees.
- Creates a separate Abandoned Hardrock Mine Fund in the Treasury to hold mill-site fee deposits. The Interior Secretary may use that money without further appropriation to carry out mine cleanup activities under the Infrastructure Investment and Jobs Act.

Bill Overview
Analyzed Economic Effects
2 provisions identified: 2 benefits, 0 costs, 0 mixed.
More mill sites for mining claims
If enacted, a mining claim owner would be able to include as many mill site claims as are reasonably necessary. Those mill sites would have to be part of a plan of operations approved by the Department of the Interior or the Department of Agriculture under existing rules. Each mill site would be limited to no more than 5 acres. Mill sites would be public land used for waste rock, tailings, or other operations tied to the claim, but they would not give mineral rights or make the land patentable. The bill would not affect the validity of existing lode or placer claims and would preserve existing claimant rights while keeping federal mining regulations and prior withdrawals in place.
New fund for abandoned mine cleanup
This bill would create an Abandoned Hardrock Mine Fund in the Treasury. Money from the claim maintenance fee on mill sites located under the bill would go into the fund. The Secretary of the Interior would be able to spend the money without another appropriation. Funds could only be used to carry out section 40704 of the Infrastructure Investment and Jobs Act, and allocations and transfers would follow that law's rules.
