“Pecos Mine Site Reclamation Project. No Trespassing,” the sign on the fence reads. As Ralph Vigil takes in the warning, he once again has a sinking feeling that the past is about to repeat itself.
Nearly 100 years ago, the old Tererro mine tore up this area, causing decades of harm to the forests, waterways and aquatic life. Standing amidst a landscape that has never fully healed, Vigil and other locals now turn their attention to the future. Eight miles from where they stand, a multinational corporation is hoping to mine untold tons of ore, threatening the fragile ecosystem once again. The name of the new venture: Tererro VMS Project.
“We gotta fight this,” Vigil says. “Our fight is for madre tierra.”
In June 2019, news of the proposal hit like a blow: Comexico, an American subsidiary of the Australian company New World Resources, sought to drill exploratory cores in the southern end of the Sangre de Cristo Mountains, a remote and dense tangle of Ponderosa pines, douglas fir and rambling creeks about 15 miles north of Pecos. The landscape holds legendary trout streams and picture-postcard vistas. It also holds an estimated 5.7 million metric tons of gold, silver, zinc, copper and lead.
Exploration would start as a relatively small operation in the Santa Fe National Forest — spanning less than 10 acres — but a full-scale mine could eventually sprawl across hundreds or thousands more acres and overwhelm the winding two-lane highway with trucks and machinery commuting up and down the mountain.
Within a week of hearing about Comexico, Vigil — a Pecos resident, organic farmer and chairman of the New Mexico Acequia Commission — was sitting down with community members and environmentalists, sketching out a plan of resistance. The coalition that emerged was historic, in his words. Groups that didn’t normally see eye to eye — acequia advocates, Indigenous leaders, environmentalists, outdoorsmen and women and government officials — all joined together under one banner: Stop Tererro Mine.
The past, they believed, was a harbinger of what was to come. The old mine operated a mere 13 years before it was shuttered in 1939, but the damage it exacted endured for generations. Willow Creek, at the foot of Elk Mountain, ran the color of rust for decades owing to the unusable ore — or waste rock — that was left to languish along its banks. Periodic rains and spring thaws sent acidic runoff into nearby waterways, polluting them with heavy metals.
The most devastating day came in the spring of 1991, when the toxic runoff rushed into the Pecos River, the lifeblood of the region. Sulfuric acid, aluminum and zinc wiped out 90,000 Rio Grande cutthroat trout at the Lisboa Springs Fish Hatchery downstream and another 10,000 in the river. The disaster almost wiped out an entire local economy built around angling, hunting and camping.
Cleanup of that site, and of El Molino, a mill on the outskirts of Pecos, followed. The area was contaminated enough to be designated a federal Superfund site, but residents, public officials and others believed the cleanup could be done better — and without the stigma of a Superfund designation — if it was undertaken differently.
As a result, the New Mexico Environment Department (NMED), several other state agencies and Freeport-McMoRan, the company held responsible, agreed to a cleanup through a consent order. The remediation has cost New Mexico taxpayers at least $8 million, Gov. Michelle Lujan Grisham has estimated: “Money is spent annually on studies and sampling with no end in sight,” she added. Much has been restored in the past 30 years, but the process is still not complete.
Questions about the old mine have lingered ever since, including whether the contaminated water could have caused illness or death in downstream communities, like Pecos. But no health studies were ever conducted as part of the legal agreement, making it almost impossible to find out.
“Whether we’re Hispano, Pueblo, or just people who love to hunt and fish and hike, that’s what unites all of us around this thing: We all want to turn on the tap and not have poison water,” said Garrett Vene Klasen, a Stop Tererro Mine coalition member and conservation director for NM Wild, a nonprofit dedicated to protecting the state’s wilderness.
Hiking along a rough Forest Service road by Indian Creek — one of several waterways near the proposed exploration site — coalition member Stephen Nelson recalls how the water ran yellow in the late 1970s, during Conoco’s exploration of the so-called Jones Hill Deposit, named for 19th-century prospector Johnie Jones.
Conoco ended up abandoning the project. But its explorations rendered much of the data that Comexico is now using to direct its own venture, which involves drilling an estimated 30 boreholes — up to 4,000 feet deep — into Jones Hill in the first phase. The long-term goal is to exploit all of the region’s many riches.
Comexico declined to answer specific questions from Searchlight New Mexico; the company will address public comments at a hearing in the future, exploration manager Pat Siglin stated by email.
But according to Comexico’s website, “the company’s ultimate objective” is to develop a “centrally located processing facility that is fed by ore from multiple deposits” and to lay the foundations of a “significant” new camp. To put it into perspective, Comexico intends to extract more than double the amount of ore that was processed at Tererro all those years ago.
The area holds undeniable promise. According to Dennis McQuillan, a retired geologist who worked at NMED and participated in Tererro’s long-term remediation, the “gold-rich Jones Hill ore body is part of a cluster of volcanic massive-sulfide (VMS) ore bodies in the region that are collectively the largest of their kind in New Mexico.”
Besides gold, the area holds deposits of copper, zinc, lead and silver, all forged by ancient volcanoes over millennia. And all are in demand. The United States Geological Survey includes zinc — used in building materials like gutters and galvanized nails — in its 2022 list of critical minerals. (The Biden administration recently recommended expanding domestic mining of these minerals to combat the “over-reliance on foreign sources.”)
Traditional Pueblo cultural sites, acequias, a vibrant recreation industry, habitats that support at-risk and endangered species — all would be imperiled if the project moves forward, coalition members argue. They cite the old Tererro Mine as a cautionary tale.
“Mining would benefit a rich corporation and a few people that are gonna make money on it, but not the community and not our heirs in our future,” said Janice Varela, a local watchdog and San Miguel County commissioner. “Our livelihoods are at stake.”
The coalition’s battle isn’t just against Comexico, though. It’s also against the General Mining Act of 1872, which grants the right to prospect and mine on federal lands. The majority of the company’s mining claims are within such federal property — the Santa Fe National Forest.
“That mining law is what needs to be changed because no tribes were invited to the table when it was made,” said Michael Martinez, a member of Ohkay Owingeh Pueblo and the Reserved Treaty Rights Lands Coordinator for Tesuque Pueblo. “They would’ve all said no.”
Lands stretching all the way to Lake Katherine in the Pecos Wilderness make up a broader “Pueblo world,” said Joseph “Brophy” Toledo, a spiritual leader at Jemez Pueblo who also has roots in Tesuque Pueblo and the historic Pecos Pueblo. Ceremonies are still performed there, Toledo, an herbalist, added. “That is a very sacred place to my people.”
“Our anatomy is the same as Mother Earth’s. And when you look at yourself as an Earth person, everything that is on Mother Earth is part of you. When mining companies come in and they start drilling, it’s like them drilling through you…They’re going through all your veins, your arteries, and they’re going through the heart.”
Signed by Ulysses S. Grant to encourage westward expansion, the 1872 law is widely reviled and has been characterized as a “sustained, systemic swindle.” But it’s been baked into the system for so long that it’s almost impervious to revisions. In 2020, the All Pueblo Council of Governors passed a resolution supporting “federal legislation to reform the 1872 Mining Act to protect Pueblo lands, sacred sites and water resources.” But the U.S. House bill they were backing failed to make it out of committee.
“The law really needs to be improved so that mining rights and claims can be denied when the environmental consequences are so high,” said Sally Paez, staff attorney at NM Wild.
