Official summary
Version 07 · Reported to House · Oct 31, 2025
This bill specifies that all federally acquired lands are eligible to be considered for hardrock mineral leasing under the Mineral Leasing Act for Acquired Lands (MLAAL). The bill defines the term hardrock mineral to (1) include deposits of minerals found in sedimentary or other rocks, base metals, precious metals, industrial minerals, and precious and semi-precious gemstones; and (2) exclude deposits of coal, oil, oil shale, gas, sodium, potassium, sulfur, or mineral materials subject to disposition under the Materials Act of 1947.
By way of background, hardrock minerals are not currently listed under the MLAAL as deposits subject to a lease, while mineral resources such as coal, phosphate, oil, gas, gilsonite, and sulfur are listed. As a result, federal lands may be leased for mining hardrock minerals only if the federal lands were acquired under a statute, such as the Weeks Act, that specifically authorizes the land to be used for hardrock mineral leasing.
No related bills are listed in this snapshot. This does not establish whether the proposal has appeared in earlier Congresses.
