BREAKING: Trump Administration to Open New Mexico’s Most Protected River to Foreign Mining Company

Key Takeaways

• Trump admin cancels 20‑year mining ban on Upper Pecos watershed.
• 163,483 acres now open to hard‑rock mining under 1872 law.
• Foreign‑owned Comexico seeks claims; no royalties paid to U.S.
• 1991 contamination killed 90,000 trout, prompting Superfund cleanup.
• State protections stay; Congress considering permanent withdrawal legislation.

Pulse Analysis

The Upper Pecos River watershed has long been a showcase of how federal land policy can safeguard critical water resources. Under the 1872 Mining Law, mineral rights on public lands can be claimed without royalty payments, a loophole that has attracted foreign investors seeking low‑cost extraction. By rescinding the 20‑year withdrawal, the Trump administration effectively re‑opened more than 160,000 acres to claim filings, giving Comexico LLC—now a subsidiary of Central Asia Metals, a London‑listed firm valued at roughly $152 million USD—unrestricted access to lead, zinc, copper, silver and gold deposits. This regulatory shift underscores the tension between historic mining statutes and contemporary environmental priorities.

Environmental stakes are high. The Upper Pecos watershed, recognized as Outstanding National Resource Waters, supports the Rio Grande cutthroat trout, acequia irrigation systems dating back centuries, and sacred sites for the Jemez and Tesuque Pueblos. A 1991 spill from the abandoned Terrero Mine released sulfuric acid and heavy metals, killing over 90,000 trout and prompting a costly Superfund‑type cleanup that still requires monitoring. Communities that organized a successful state‑level protection now face the prospect of renewed mining activity that could repeat past contamination, jeopardizing water quality for downstream users in New Mexico and Texas.

Policy implications extend beyond New Mexico. The rapid reversal—accomplished with a single‑page notice—highlights the vulnerability of executive withdrawals, which can be undone without public comment. Lawmakers are responding with the Pecos Watershed Protection Act, aiming to cement a permanent federal withdrawal and add additional wilderness acreage. The episode mirrors similar rollbacks in Nevada’s Ruby Mountains and the Boundary Waters, signaling a broader pattern of prioritizing short‑term resource extraction over long‑term ecological and cultural stewardship. Stakeholders, from local farmers to investors, must monitor legislative developments, as congressional action may become the decisive factor in preserving the Upper Pecos for future generations.
