Read twice and referred to the Committee on Energy and Natural Resources.

What it does
This bill would withdraw federal land within the Rio Chama Watershed area of New Mexico from all forms of mineral entry, location, and patent under federal mining laws — meaning no new mining claims could be staked on that federal land. The withdrawal applies only to federally owned minerals and would not affect mineral rights held by, or in trust for, Indian Tribes or qualified land grant-merced communities. The bill also explicitly preserves the traditional, customary, and personal gathering of common materials (such as sand, gravel, clay, and adobe) by members of land grant-merced and acequia communities for domestic, cultural, religious, or noncommercial purposes.
Who benefits
Residents and communities downstream of the Rio Chama who rely on the watershed for drinking water, agriculture, and recreation. Tribal nations with recognized mineral rights or traditional uses in the area, whose existing interests are explicitly protected. Members of historic land grant-merced and acequia communities, whose customary gathering rights are preserved. Outdoor recreation businesses (fishing, rafting, hiking) that depend on a healthy watershed. Environmental and conservation organizations seeking to protect the area from mining-related water quality impacts.
Who is hurt
Mining companies and prospectors who would be barred from staking new claims on the affected federal land. Mineral exploration and extraction industries that may have had commercial interest in the area's subsurface resources. Workers in the mining sector who might otherwise have been employed on projects in the region. Local and state governments that could have received royalty revenues from mineral extraction on federal land. The federal government would forgo any future royalty income from mining activity on the withdrawn land.
Supporters argue
Supporters argue that the Rio Chama Watershed is a critical source of drinking water and agricultural irrigation for communities in northern New Mexico, and that mining activity poses documented risks of acid mine drainage and heavy metal contamination to surface and groundwater. They contend the bill respects the rights of Indigenous and historic land grant communities by explicitly carving out their mineral interests and traditional gathering practices — a model of equitable conservation. They further argue that Congress has clear, well-established authority to withdraw federal lands from mining entry under the Federal Land Policy and Management Act, making this a legally straightforward exercise of congressional power.
Opponents argue
Opponents argue that withdrawing federal land from mineral entry forecloses economically valuable resource development without a full assessment of what minerals may exist in the area or what their extraction could contribute to local employment and federal revenues. They contend that blanket withdrawals reduce domestic mineral production at a time when the U.S. is seeking to expand supply chains for critical minerals, and that site-specific environmental review under existing law — such as NEPA — already provides adequate protection against harmful mining projects without a permanent legislative ban. They also argue that the boundary area is defined by a map not included in the bill text, creating ambiguity about the precise scope of the withdrawal.
