The Bureau of Land Management is seeking public comments for additional analysis of a processing facility related to the approved American Magnesium Foothill Dolomite mine near Deming in Luna County.

The BLM’s 2020 approval of the mine was challenged in U.S. District Court. The court directed BLM to analyze the impacts on water quality that could result at an associated processing facility proposed on private surface acres. The court did not reverse BLM’s decision to approve the plan of operations, and the approved plan remains in effect.

The BLM is now seeking public comments on a supplemental analysis of potential impacts to water quality from the proposed processing plant on private lands, based on a conceptual industry standard design.

Additional information is available at the BLM National NEPA Register, where comments may be submitted by selecting the “Participate Now” option. The comment period will close March 2, 2026. For more information, please contact BLM Las Cruces Minerals Program Lead Corey Durr at 575-525-4345 or [email protected].
