Mining Regulatory Clarity Act

This bill would allow mining operators to use federal lands for support activities, such as waste disposal, without first proving that those specific lands contain valuable mineral deposits. It proposes to clarify that operators may include necessary mill site claims within their plans of operations and establishes the Abandoned Hardrock Mine Fund to receive fees from these claims. The Department of the Interior would be required to use these funds for the reclamation of abandoned hardrock mines.

This bill affects mining operators by allowing them to use federal lands for ancillary activities, such as waste disposal, without first establishing the presence of valuable mineral deposits. The Department of the Interior is also affected, as it is required to manage the newly established Abandoned Hardrock Mine Fund for reclamation activities. Additionally, the legislation impacts entities involved in abandoned hardrock mine reclamation who may benefit from the fund's resources.

• Authorization of ancillary mining activities on federal lands. The bill allows mining operators to use federal lands for activities such as waste disposal regardless of whether those lands contain valuable mineral deposits. This provision addresses a 2022 court decision regarding the Rosemont Copper Mine that required mineral validity to be established for such claims.
• Expansion of mill site claims. Mining operators are permitted to locate and include as many mill site claims within their plan of operations as are reasonably necessary for their activities. This includes areas designated for waste rock disposal and other uses necessary to support mining operations.
• Establishment of the Abandoned Hardrock Mine Fund. The bill creates a dedicated fund for the reclamation of abandoned hardrock mines. Revenue generated from mill site claim fees must be deposited into this fund for use by the Department of the Interior.
• Land use under approved plans of operations. The legislation authorizes mining operators to use or occupy public land for mining-related purposes provided the activities are conducted in accordance with an approved plan of operations.

This bill modifies the application of the Mining Act by clarifying the use of mill site claims for mining waste disposal, directly addressing a 2022 U.S. Court of Appeals decision regarding mineral validity requirements. It also establishes the Abandoned Hardrock Mine Fund to manage revenue generated from these claims for reclamation activities.

The bill seeks to clarify federal land use regulations for mining by allowing operators to use public lands for ancillary activities, such as waste disposal, without first proving the land contains valuable mineral deposits. It aims to address legal precedents regarding mining claim validity while establishing a dedicated fund for reclaiming abandoned hardrock mines.
